Deliverables All files are located in the subdirectory of the website. The website should function as follows: You should have a page that, when run, displays a page showing the text "Greetings and Salutations. I will master ASP.NET in this course." You should also have a second page that is the annual salary calculator that properly calculates the annual salary, given an hourly rate and the number of hours projected to be worked in a year. Once you have verified that both pages work, save your website, zip up all files, and submit in the Dropbox. Please watch the tutorial before beginning the iLab. Table of Contents Tutorial Part 1 Tutorial Part 2 Tutorial Part 3 Tutorial Part 4 Play00:00MuteFullscreen Transcript iLab Steps NOTE Submit your assignment to the Dropbox, located at the top of this page. For instructions on how to use the Dropbox, read these step-by-step instructions. (See the Syllabus section "Due Dates for Assignments & Exams" for due dates.) In this iLab, you will create an Annual Salary Calculator ASP.NET Web application using Visual Studio.NET. For the iLabs, you will use the Microsoft Visual Studio software application. You have two options for using this application: You may use a copy of Visual Studio that is installed on your local PC. If you do not already have this software, there is a link in the Syllabus (in the Textbook and Required Materials section) that you can follow to obtain a copy at low or no cost through the DeVry Student Software Fulfillment Center. or You may run Visual Studio over the Web from the DeVry iLab (Citrix) server. Instructions for using the iLab (Citrix) server are on the iLab page under Course Home. Throughout this course, you will be creating a Web application for a fictitious company called ACIT (Academy of Computing and Information Technology). To get familiar with the development environment, follow the Lab Steps to create a simple Annual Salary Calculator ASP.NET Web application. You will be adding to this application each week. Overview of Fictitious Company Image of Academy of Computing and Innovation Technology The Academy of Computing and Information Technology is a mid-size indie (independent) film studio that is in need of a payroll system. We have outgrown our current system, a simple spreadsheet, to the extent that it takes three people over one week to pay everyone on a timely basis. Overview of Our Company We have over 2,000 full-time and part-time employees. We produce comedy, fiction, and science fiction films with budgets of $250K–$20 million. We have produced over 50 films since we first began 20 years ago. We are very profitable and have strong links to many of the industry's most powerful people. Current Payroll System Our current system consists of mostly manual processing using an MS Excel spreadsheet to control who gets paid. The system consists of the three payroll staff members reviewing each of the full-time staff members' wages, calculating how many hours they worked based on their hourly rate, and paying them by issuing a check. The check needs to be entered in another worksheet for each of the people who were paid so that we can tell when it went out, how much it was for, and if it was cashed or not. If a [Date_Cashed] is entered, we deduct that amount from our working payroll capital account to track how much money we have for payroll. This process is then repeated for all part-time staff and independent contractors. Our Needs We need a more automated way to pay our staff. We need to use the same logical flow as a basis, yet improve on it by having a way to easily calculate the projected annual salary based on rate and number of hours; search, enter, update, and delete staff and independent employee information in one place; search, enter, update, and delete payroll automation information for the employee to set up recurring payments or one-time payments; produce reports to show the following: (a) summary of who got paid per week, (b) summary of all payments per week, (c) details of any employee to-date (allow entry of a specific employee ID); allow transactions to be rolled back in case we pay someone too much; make use of transaction processing in case the system unexpectedly shuts down; ensure the system is secure (logins required); allow only authorized payroll personnel to control all aspects of the system; allow only authorized payroll personnel to view transactions and user activity; allow only authorized payroll personnel to e-mail reports to users using the e-mail on file; and incorporate error handling into all processes in the system and e-mail any errors to the technical support people. Required Software Microsoft Visual Studio.Net Access the software at https://lab.devry.edu. Steps: 1, 2, and 3 STEPs 1–3: Create Website and Home Page Please watch this video for a similar example to the one we are doing. It introduces event handlers, getting data from textboxes, performing basic calculations, and formatting the output to be displayed: In this iLab, we will learn how to create a simple ASP.NET Web application using Microsoft Visual Studio.NET. The application will display the text "Hello, World" on the home page. 1. Open Microsoft Visual Studio. Image of main screen 2. Create a new ASP.NET website called "PayrollSystem." To do this, select File -> New -> Web Site Image of navigation to new website option You will get the following screen which shows Visual Basic.

To do this, if necessary, click the Design button below the editing window to switch to Design view, then click in the editing window and type " Greetings and Salutations. I will master ASP.NET in this course." (without the quotes) to get the following screen. Image of Design View screeen with test Click the Save button on the toolbar to save the changes to Default.aspx. STEPs 4–5: Start Debugging; NOTE: Citrix users have different steps! 3. To ensure that everything is working properly, click the Start Debugging button on the toolbar, or press the F5 key on the keyboard, or pull down the Debug menu and select Start Debugging. Image of debugging screen Save and run by Right-Click-> Run from Browser. Image of menu option for debugging Press Yes. Image of message to save file Click the Start Debugging button on the toolbar, or press the F5 key on the keyboard, or pull down the Debug menu and select "Start Debugging." Image of blank debugging screen Image of start debugging option selected Image of debugging not enabled message Notice that this time the project build and website validation started. If the Debugging Not Enabled dialog box appears, select the option to add or modify the Web.config file to enable debugging and click OK. You should only have to do this the first time you debug the site. You will get a clean run just as you did previously. Your output screen looks like the screen below. Image of output screen NOTE: To execute the application, you have these options: If you are using Citrix, press CTRL + F5 to Start Without Debugging. You will not be deducted points for this part. If you are using a standalone version, press F5 to Start with Debugging, or you can press CTRL + F5 to Start Without Debugging. Create the Salary Calculator Form 1. Right click on the Project name. Choose Add, then Select Web Form to get the screen below. Image of Add Web Form menu And you get the Add New Item screen, shown below. Image of result Add new item screen 2. Select the name of the form you will add frmSalaryCalculator.aspx. Make sure "Place code in separate file" is checked and "Select master page" is unchecked. You will create a Web-based salary calculator on this new page. Click the Design view. Add the Tools Window using View-> Toolbox. Image of Toolbox option selected Image of toolbox menu 3. You can choose to adjust the ToolBox to tab with Solution Explorer to look like the following screen. Image of blank screen when toolbox to tab is adjusted You will create a Web-based salary calculator on this new page. To do this, open the aspx page in Design view and, from the Toolbox, drag a label into the form, click after the label and add about 5 spaces, then drag a textbox control after the label. Press Enter after the textbox to put the cursor on the next line. Add another label and textbox below the first set and press Enter. Then add a button control. Finally, on the last line, add another label. Your form should look like the screen displayed below. Image of calculator screen with labels and button 4. If necessary, add the Property Window as shown in the screen below, using View->Properties Window. Image of Property Window 5. Now we will modify the page to add proper labels and give the textboxes names. Change the text displayed in each label so that the first label displays Annual Hours; the second label should display Rate; and the third label should display $. To change the text displayed, click on the label control. This causes the property window to show all properties of the label, then change the Text property of the control in the Properties window. Set the ID property of the top textbox to txtAnnualHours. Set the ID property of the second textbox to txtPayRate. Set the ID of the bottom label (the one we set the text property to "$") to lblAnnualSalary. (Note: We set these IDs as we will be accessing the control values from the C# code. You can set the button ID and the other two labels' ID properties as well, but we won't be accessing them from our code.) Change the button text to display Calculate Salary. (Hint: To change the text displayed as the button label, change the Text property of the button.) The ID of the button should be btnCalculateSalary.Your form should now look like the screen displayed below. Image of calculator screen with blank values This code will be called each time the user presses the button. It is important to remember that code in the code behind page executes on the server, not on the user's browser. This means that when the button is pressed, the page is submitted back to the Web server and is processed by the ASP.Net application server on the Web server. It is this code (between the { and } in this method) that will execute on the server. Once it is done executing, the page will be sent back to the browser. Any changes we make to the page or controls on the page will be shown to the user in the updated page. In this method, add code that will get the text in the txtAnnualHours text box, convert it to a Double, and store it in a double variable. Add code that will get the text from the txtPayRate text box, convert it to a Double, and store it in another variable. Create a third variable of type Double and set its value to the annual hours variable value multiplied by the rate double variable value. Take this resulting value and convert it to a string (text), and update the lblAnnualSalary Text property with this new string. Let's look at a similar example. After reviewing this example, write the code needed to calculate the annual salary. CostOfRoom Calculator is the alternate example, which demonstrates the skills you need to complete this assignment. See video at the top of this lab document and screenshots below. What follows is an example of code-behind the Calculate button for the CostOfRoom Calculator: Code-behind the calculate button A control's property can be accessed by simply using the control ID followed by a . followed by the name of the property. For example, the value stored in the Text property of the txtAnnualHours control can be accessed by using this: txtAnnualHours.Text. Text properties on controls are of type string. The output of the CostOfRoom calculator is shown in the screen below with Length, Width, Cost Per Square Unit labels and input boxes, and the Calculations button. Image of output CostOfRoom Calculator with length, width, cost per square unit values and calculations. Use small values for length and width. Use large values for length and width and see the formatting of the output. Image of CostOfRoom calculator with revised values for length, width, cost per square unit and calculations. To convert a string to a Double you can use the Convert class. If we had a string variable called str1 and a double variable called myNumber, the C# code to convert this would be as follows: When converting from one type to another, we are assuming that the value stored in the type being converted is compatible with the type with which we are converting. In the example above, if the value stored in str1 was not a type compatible with a Double (for example, tiger), an error would be raised. All of the base types in C# (double, int etc) have a ToString() method that you can call. If you had a double variable that you wanted to convert to a string and set that string to my label's text, you would do the following: This would take whatever value was stored in the myNumber Double and convert it to a string. Set your new form as the start page by clicking once on the form name in the Solution Explorer and then right-clicking on the form name and selecting Set as Start Page. You can now test your application and make sure it works correctly as you did with the Hello World form above. You can switch back and forth between which form runs when you run your application by setting the different forms as the start page. The final result should look something like the screen below with the Annual Hours, Pay Rate, Calculate Salary button, and result. Image of result screen Annual Hours, Pay Rate, Calculate Salary button, and result. Once you have verified that your project works, save your project, zip all files, and submit in the Dropbox. NOTE: Please download and review the Doc Sharing files Web Lab and Citrix.zip, which contain information on how to FTP to the DeVry University website and how to use Citrix for the assignments.

ilab 2

iLab 2 of 7: User Input Pages In this lab, we will demonstrate how to create an ASP.NET Web application having a single form with five text boxes and a Submit button. We will use the form to send information to a second form where data from the first form will be displayed. We will also add a main navigation page with two different ways of linking to other pages. Please watch the tutorial before beginning the iLab. Table of Contents Tutorial: Part 1 Tutorial: Part 2 Tutorial: Part 3 Tutorial: Part 4 Tutorial: Part 5 Tutorial: Part 6 Tutorial: Part 7 Tutorial: Part 8 Play00:00MuteFullscreen Transcript Deliverables NOTE Submit your assignment to the Dropbox, located at the top of this page. For instructions on how to use the Dropbox, read these step-by-step instructions. (See the Syllabus section "Due Dates for Assignments & Exams" for due dates.) All files are located in the subdirectory of the website. The website should function as follows: When you run the website, you will be presented with a page (frmMain) that allows you to go to the different parts of the website that you are developing. You will be able to go to the Annual Salary Calculator that we added last week and to the data entry form for personnel this week. When you go to the personnel data entry page, you should be able to enter data in the frmPersonnel form and have it displayed in the frmPersonnelVerified form. Your salary calculator will also be available from the main page and will calculate properly when you enter data. Each page should link back to the main page via the ACIT logo hyperlink. Once you have verified that it works, save your website, zip up all files, and submit in the Dropbox. Each page (except frmMain) will include the ACIT logo that is hyperlinked back to frmMain. Required Software Microsoft Visual Studio.Net Access the software at https://lab.devry.edu. Steps: 1, 2, and 3 Lab Steps STEP 1: Create Web Forms Open the payroll system website from Lab 1. 2. Create a new form called frmPersonnel. To do this, pull down the website menu, select Add New Item, then type frmPersonnel.aspx for the name. And you will get the following screen: Change Default.aspx to frmPersonnel.aspx. And get the following Screen: 3. Go to the Design mode of the form by clicking the Design tab (as opposed to the Source tab). 4. From the ToolBox, drag and drop an Image control. 5. Next, right click on the Project folder name in the Solution folder. Click Add-> New Folder and name the folder Images. 6. Right click on the Images folder and choose Add->Existing item. We will add our logo to our Images folder. Be sure to choose All Files from the Files of Type and navigate to where you saved the image. The logo image is located in Doc Sharing in our course for you to download to your own machine or upload to Citrix. 7. After you have loaded the logo to the project, select the image control on your page. 8. On the Properties window, choose the ImageURL property and the ellipse to the right of this property to open a Browse dialog box and add the ACITLogo to the page. 9. The Logo should appear on your page as shown. 10. From the ToolBox, drag-and-drop a Panel control underneath the logo image. 11. Click the A/Z button in the Properties dialog so that all of the properties are sorted alphabetically. 12. Change the height property of the Panel to 250px and the width to 300px. To do this, select the Panel, then go to the Properties pane (usually in the lower right corner of the Visual Studio.NET Design view; if you don't see it, click the View Properties window OR press the F4 key). Scroll down the list, then type the value in for each property. 13. Change the panel's HorizontalAlign property to left. 14. Save your work! 15. From the ToolBox, drag-and-drop five Labels and five TextBoxes onto the Panel. To make each Label/TextBox pair appear on a separate line, put the cursor after each TextBox, then press the [ENTER] key (much like you would a with a word processing program). Rename the Label's properties as defined below. You can do this by selecting each Label, scrolling to the property, and then typing in the value. Property Value Label1 – Text First Name: Label2 – Text Last Name: Label3 – Text Pay Rate: Label4 – Text Start Date: Label5 – Text End Date: Rename each TextBox's property as defined below. You can do this by selecting each TextBox, scrolling to the property, and then typing in the value. Property Value TextBox1 – (ID) txtFirstName TextBox2 – (ID) txtLastName TextBox3 – (ID) txtPayRate TextBox4 – (ID) txtStartDate TextBox5 – (ID) txtEndDate Change each button's ID and Text properties as defined below. You can do this by selecting each button, scrolling to the property, and then typing in the value. Property Value Button1 – (ID) btnSubmit Button1 – Text Submit Button2 – (ID) btnCancel Button2 – Text Cancel Save your work! 16. If you would like, you can make the labels the same size by selecting the first label, pressing and holding Control, and selecting the rest of the labels. Then, choose Format-> Make Same Size ->Width as shown below: 17. When we click the Submit button, we want the contents of the form to be passed to another form. In the Solution Explorer, right click on the project name and choose Add-> Add New Item. Choose Web Form and name the form frmPersonnelVerified.aspx. 18. On this form, we will add an image and panel like the previous form. Within the panel, add a label and a textbox. The width of the panel should be 650 and the height 250. The label should say Information to Submit. The textbox ID should be txtVerifiedInfo. Also, change the TextMode Property of the textbox to MultiLine, the height to 80, and the width to 400. Click the Design tab for the frmPersonalVerified.aspx, and add a Label and a TextBox. Set the properties as follows: Property Value Label – Text Information to submit Textbox – (ID) txtVerifiedInfo Textbox – Height 80px Textbox – Width 400px Textbox – TextMode Multiline 19. Next, we will write the code that will load the information from the frmPersonnel page to the frmPersonnelVerified page. Be sure that your cursor is not selecting the panel. Double click on the blank part of the page to open the page_load event handler and add the following code. 20. Return to the frmPersonnel Web page, click the btnSubmit button, go to the PostBackUrL property and set it to frmPersonalVerified.aspx by clicking the ellipse to the right of the property to open a Browse dialog, and click frmPersonalVerified.aspx there. This will insert the correct path to the PostBackUrl Property. 21. Test your Web page. On the frmPersonnel.aspx page, right click and choose View in Browser. Test the application with test data and press Submit. You should see your test data appear in the frmPersonnelVerified page. STEP 2: Adding Navigation 22. Add a new Web form called frmMain.aspx Add the ACIT Logo to the top of the form and a panel below the image with height = 350 and width = 500. Add an ImageButton control, then, space over, and next, add a LinkButton. 23. For the Image button, you will need to download an image from the Internet or create an image yourself. Right click on the Images folder and choose Add->Existing item and browse to add the image that you want to use as part of your project. 24. Click on the ImageButton and the ImageUrl property. Then, select the image that you added to the project. Modify the text of the LinkButton to Annual Salary Calculator. 25. Set the PostBackURL property for the image and the link to the frmSalaryCalculator.aspx from last week. 26. Right click on the frmMain.aspx and choose Set As Start Page. 27. Test your Web page. Press F5, or click the Start Debugging (Citrix users, press Start Without Debugging) button on the toolbar, or pull down the Debug menu and select Start Debugging. Test your link. Does it take you to the Annual Salary Calculator page? NOTE: To execute the application, you have these options: If you are using Citrix, press CTRL + F5 to Start Without Debugging. You will not be deducted points for this part If you are using a standalone version, press F5 to Start with Debugging, or you can press CTRL + F5 to Start Without Debugging. On your own: Repeat this process to create an image and link for the frmPersonnel.aspx page. Remember to set the PostbackURL properties. On the frmPersonnel page, make the ACIT logo be a link that will take the user to the frmMain page. Use an ASP.Net Hyperlink control to do this task. Update the frmPersonnel, frmPersonnelVerified, and frmSalaryCalculator to include the ACIT logo at the top of each page with the logo set as a hyperlink that will return to the frmMain page. On the frmPersonnel page, make it so that if the user presses the Cancel button, then that user is taken back to the frmMain. STEP 3: Verify and Submit 28. Save your work and run the project. You should be able to go to both areas of your site and enter the information in the pages. Your calculator should properly calculate without errors, and then on the frmPersonel Web page, you can click the Submit button and have it display in the frmPersonalVerified Web page. Once you have verified that it works, save your project, zip up all files, and submit in the Dropbox. NOTE: Make sure that you include comments in the C# code where specified (where the "//Your comments here" is mentioned), or else a 5-point deduction per item (form, class, function) will be made. This includes code that you will be creating in the coming weeks. To comment on the code, you basically put two forward slashes to start the comment; anything after the slashes on that line is disregarded by the compiler. Then, type a brief statement on what is happening in the line under it. Comments show professionalism and are a must in systems. As a professional developer, comments will set you apart from others and make your life much easier if maintenance and debugging are needed.

ilab 3

iLab 3 of 7: User Activity Monitoring (30 points) In this lab, we will demonstrate how to save user activity data in a database. We will be creating a new form to display the user activity data, a new dataset to contain the data, a data access class to structure the code, and a function within the data access class to save users' activity data when users visit the Personnel form page (frmPersonnel.aspx). We will also be adding server side validation to the frmPersonnel form you added in the previous lab and update the main menu for the new functionality. Please watch the tutorial before beginning the iLab. Table of Contents Tutorial: Part 1 Tutorial: Part 2 Tutorial: Part 3 Tutorial: Part 4 Play00:00MuteFullscreen Transcript Deliverables NOTE Submit your assignment to the Dropbox, located at the top of this page. For instructions on how to use the Dropbox, read these step-by-step instructions. (See the Syllabus section "Due Dates for Assignments & Exams" for due dates.) All files are located in the subdirectory of the project. The project should function as specified: When you visit the Personnel form page (frmPersonnel.aspx), a record should be saved in the tblUserActivity table with the IP address, form name accessed (frmPersonnel), and the date accessed. When you click the View Activity button, you should see at least one record with this information. When the user goes to the frmPersonnel web form and enters data, the following business rules are to be enforced. Fields may not be empty or filled with spaces. If any field is empty, turn that field background color to yellow and add to/create an error message to be shown in the error label. The end date must be greater than the start date. If the end date is less than the start date turn both date fields yellow and add to/create an error message to be shown in the error label. If all fields validate properly, then the session state items should be set properly and the user should see the frmPersonnelVerified form with all the values displayed. You will also add a new item to frmMain that will take the user to the new frmUserActivity form you added. Add the proper link and a hyperlinked image to allow the user to select this new option. Once you have verified that everything works, save your website, zip up all files, and submit it to the Dropbox. Required Software Microsoft Visual Studio.Net Access the software at https://lab.devry.edu. Steps: 1, 2, and 3 Lab Steps STEP 1: Step Title 1. Open Microsoft Visual Studio.NET. 2. Open the PayrollSystem website by clicking on it in the Recent Projects list, or by pulling down the File menu, selecting Open Website, navigating to the folder where you previously saved the PayrollSystem, and clicking Open. 3. Download the PayrollSystem_DB.accdb file from Doc Sharing and save it on your local computer. (Note: your operating system may lock or block the file. Once you have copied it locally, right click on the file and select Properties and then Unblock if available). Then add it to the PayrollSystem website as follows: In Visual Studio, in the Solution Explorer click Website, Add Existing Item, then navigate to the PayrollSystem_DB.accdb file you downloaded, and click the Add button. Make sure you select file types, which include *.accdb, *.accdb, etc. Otherwise, you will not be able to see the database file to select. 4. Now we need to create a new connection to the PayrollSystem_DB.accdb. To begin, click View Server Explorer. 5. When the Server Explorer toolbox appears, click the Connect to Database button. 6. When the Add Connection dialog appears, click the Change button. In the Change Data Source dialog, select MS Access Database File; Uncheck Always use this Selection; then click OK. Press Continue to get the following screen. 7. Click the Browse button to navigate to the PayrollSystem_DB.accdb file in your website folder, then click Open. (NOTE: Be sure you select the PayrollSystem_DB.accdb file in your PayrollSystem website folder, not the one you originally downloaded from Doc Sharing!) Click Test Connection. You should receive a message that the test connection succeeded. Click OK to acknowledge the message, then click OK again to close the Add Connection dialog. 8. The PayrollSystemDB.accdb should be added to the Server Explorer. Expand the database, then expand the Tables entry under the database until you see tblUserActivity. Leave the Server Explorer window open for now as you will be returning to it in a moment. 9. Create a new dataset by selecting Website-> Add New Item. Under Templates, select the Dataset item. Enter dsUserActivity.xsd for the name. Click Add. 10. If the following message appears, select Yes. You want to make this dataset available to your entire website. 11. If the TableAdapter Configuration Wizard dialog appears, click Cancel. (We will be configuring a Data Adapter for this dataset later in C# code, so we do not need to run this wizard.) 12. Drag-and-drop the tblUserActivity table from the Server Explorer window into the dsUserActivity dataset in the editor window. NOTE: If you see a message that says your connection uses a local data file that is not in the current project, that indicates you did not select the correct PayrollSystem_DB.accdb file when you created your data connection. To fix this problem, click No, then right-click on PayrollSystemDB.accdb in the Server Explorer window and choose Modify Connection. Click the Browse button, navigate to the PayrollSystemDB.accdb file that is in your PayrollSystem website folder, and click Open. Test the connection, then click OK. Click the Save icon on the toolbar to save the dsUserActivity.xsd dataset. (You can now close the Server Explorer window if you wish.) 13. Create a new class to contain the C# code that will access this dataset. To do so, click Website, Add New Item. In the Add New Item dialog, select the Class template, and enter clsDataLayer for the name. Make sure the Language is set to Visual C#. Click Add. 14. If the following message appears, select Yes. You want to make this class available to everything in your solution. 15. Add the following to the top of your class, below any other using statements created for you by Visual Studio. Add to top of class // Add your comments here using System.Data.OleDb; using System.Net; using System.Data; 16. Add the following three functions inside the squiggly braces for the public class clsDataLayer class, above the beginning of the public clsDataLayer() constructor and save the class. Class // This function gets the user activity from the tblUserActivity public static dsUserActivity GetUserActivity(string Database) { // Add your comments here dsUserActivity DS; OleDbConnection sqlConn; OleDbDataAdapter sqlDA; // Add your comments here sqlConn = new OleDbConnection("PROVIDER=Microsoft.ACE.OLEDB.12.0;" + "Data Source=" + Database); // Add your comments here sqlDA = new OleDbDataAdapter("select * from tblUserActivity", sqlConn); // Add your comments here DS = new dsUserActivity(); // Add your comments here sqlDA.Fill(DS.tblUserActivity); // Add your comments here return DS; } // This function saves the user activity public static void SaveUserActivity(string Database, string FormAccessed) { // Add your comments here OleDbConnection conn = new OleDbConnection("PROVIDER=Microsoft.ACE.OLEDB.12.0;" + "Data Source=" + Database); conn.Open(); OleDbCommand command = conn.CreateCommand(); string strSQL; strSQL = "Insert into tblUserActivity (UserIP, FormAccessed) values ('" + GetIP4Address() + "', '" + FormAccessed + "')"; command.CommandType = CommandType.Text; command.CommandText = strSQL; command.ExecuteNonQuery(); conn.Close(); } // This function gets the IP Address public static string GetIP4Address() { string IP4Address = string.Empty ; foreach (IPAddress IPA in Dns.GetHostAddresses(HttpContext.Current.Request.UserHostAddress)) { if (IPA.AddressFamily.ToString() == "InterNetwork") { IP4Address = IPA.ToString(); break; } } if (IP4Address != string.Empty) { return IP4Address; } foreach (IPAddress IPA in Dns.GetHostAddresses(Dns.GetHostName())) { if (IPA.AddressFamily.ToString() == "InterNetwork") { IP4Address = IPA.ToString(); break; } } return IP4Address; } STEP 2: frmUserActivity, frmPersonnel, frmMain 17. Create a new web form called frmUserActivity. Switch to Design Mode and add the ACIT logo to the page as an ImageButton and link it back to frmMain. Below the image button add a panel. To the panel, add a Label and GridView (found under the Toolbox, Data tab) having the following properties. Property Value Label – Text User Activity GridView – (ID) grdUserActivity 18. Go to the Page_Load method by double clicking an empty space on the page and add the following code. Page_Load method for frmUserActivity.aspx if (!Page.IsPostBack) { // Declares the DataSet dsUserActivity myDataSet = new dsUserActivity(); // Fill the dataset with what is returned from the function myDataSet = clsDataLayer.GetUserActivity(Server.MapPath("PayrollSystem_DB.accdb")); // Sets the DataGrid to the DataSource based on the table grdUserActivity.DataSource = myDataSet.Tables["tblUserActivity"]; // Binds the DataGrid grdUserActivity.DataBind(); } 19. Open the frmMain form, add a new link button and image button to point to the new frmUserActivity. Find an image to use for the image button and add the new option as View User Activity. 20. Go to the frmMain Page_Load and add the following code. frmMain.aspx Page_Load code // Add your comments here clsDataLayer.SaveUserActivity(Server.MapPath("PayrollSystem_DB.accdb"), "frmPersonnel"); 21. In the Solution Explorer, right click on the frmMain.aspx form and select Set As Start Page. Run your project. When you open the project, a record should be saved in the tblUserActivity table with the IP address, form name accessed (frmPersonnel), and the date accessed. When you click the View Activity button, you should see at least one record with this information. 23. You will now add server side validation code to the frmPersonnel page. Currently, when the Submit button is pressed, the frmPersonnelVerified page is displayed. This is because the frmPersonnelVerified page is set as the Submit button's PostBackUrl property. Instead of having the page go directly to the frmPersonnelVerified page when the Submit button is pressed, we want to do some server side validation. If any of the validation rules fail, we will redisplay the frmPersonnel page with the fields in question highlighted in yellow with an error message displayed. First, it is important to understand what is currently happening when the submit button is pressed. This is causing a postback of the form to the frmPersonnelVerified form. When this postback happens, all of the data in the fields on the frmPersonnel form are sent to the frmPersonnelVerified form as name value pairs. In the Page_Load code of frmPersonnelVerified these values are picked up from the Request object and displayed. Each name value pair will be in the Request object as the ID of the control containing the value and the value itself. We can pass data between pages by using Session state instead. In order to do validation on the values but still have the values visible on the frmPersonnelVerified page, we will need to change not only the PostBack URL of the frmPersonnel page but also how the frmPersonnelVerified form is getting the data—it will need to get it from Session state rather than from the Request object. In order to do this, we will make the following changes. Clear the Submit button PostBackURL Property on the frmPersonnel form. Remove the value in the PostBackUrl that is highlighted. In the btnSubmit_Click event handler get each value from the data entry fields and set Session state items for each. (instructions below) Change the frmPersonnelVerified code behind to get the values from the Session state items you created in the previous step. (instructions below) When you are done with these steps, you should be able to enter data on the frmPersonnel data entry form and then click the Submit button. The frmPersonnelVerified page should then be displayed with the values that were in the data entry fields on frmPersonnel. 23. Add a label to the frmPersonnel form with an ID of lblError. Do not place the label to the right or left of any of the controls on the form. Add it below the controls or above the controls. The text property of this label should be set to an empty string. 24. Add code to perform server side validation in response to the submit button being clicked. Here are the business rules we want to enforce (remember this will be server C# code in the frmPersonnel code behind): Fields may not be empty or filled with spaces. If any field is empty, turn that field background color to yellow and add to/create an error message to be shown in the error label. The end date must be greater than the start date. If the end date is less than the start date, turn both date fields yellow and add to/create an error message to be shown in the error label. If all fields validate properly then the session state items should be set properly and the user should see the frmPersonnelVerified form with all the values displayed. frmPersonnel.aspx Lab Hints 1. The server side validation should be in the Submit button's event handler. There is a Trim method on the string object that will automatically remove spaces from the beginning and end of a string. To test if txtFirstName is empty or filled with spaces, use the following code. if (Request["txtFirstName"].ToString().Trim() == "") 2. To set the background color of the txtFirstName field, use the following code. txtFirstName.BackColor = System.Drawing.Color.Yellow; 3. To set a value in session state and redirect the response to the frmPersonnelVerified.aspx do the following. txtFirstName is the key and txtFirstName.Text is the value. Session["txtFirstName"] = txtFirstName.Text; //Need to set session variables for all text boxes Response.Redirect("frmPersonnelVerified.aspx"); 4. You may want to create variables to work with for validation rather than using the Request item objects directly. To turn a string into a DateTime object you can use the DateTime method Parse. If you had a date value stored in a string called strDate, you could turn it into a DateTime object like this. DateTime myDateTimeObject = DateTime.Parse(strDate); You can compare two DateTime objects by using the DateTime.Compare method. If you had two DateTime objects called dt1 and dt2 you can check to see if dt1 is greater than dt2 by doing this. if (DateTime.Compare(dt1,dt2) > 0) DateTime.Compare will return a 0 if the two dates are equal, a 1 if dt1 is greater than dt2, and a -1 if dt1 is less than dt2. If you put in an invalid date for either of the date fields, you will get an exception/server error when trying to parse the values. We will address this in a later lab—for now make sure you enter valid dates (valid meaning a date in the form of mm/dd/yyyy). 5. An example of the code you might want to use to test if the end date is after the start date follows. DateTime startDate = DateTime.Parse(Request["txtStartDate"]); DateTime endDate = DateTime.Parse(Request["txtEndDate"]); if (DateTime.Compare(startDate, endDate) > 0) { txtStartDate.BackColor = System.Drawing.Color.Yellow; txtEndDate.BackColor = System.Drawing.Color.Yellow; Msg = Msg + "The end date must be a later date than the start date."; //The Msg text will be displayed in lblError.Text after all the error messages are concatenated validatedState= false; //Boolean value - test each textbox to see if the data entered is valid, if not set validState=false. //If after testing each validation rule, the validatedState value is true, then submit to frmPersonnelVerified.aspx, if not, then display error message } else { txtStartDate.BackColor = System.Drawing.Color.White; txtEndDate.BackColor = System.Drawing.Color.White; } Remember to clear the PostBackURL property of the Submit button! frmPersonnelVerified.aspx Lab Hints When using the Session state in frmPersonnel.aspx for txtFirstName, you used the following code: Session["txtFirstName"] = txtFirstName.Text; To get this same value back from the session we use the key and the Session object in the Page_Load of frmPersonnellVerified.aspx (instead of using Request, use Session) as follows. Session["txtLastName"].ToString() STEP 3: Verify and Submit 23. View the video above on what functions your lab should have so far. 24. Run your project. When you open the project and go to the main menu form a record should be saved in the tblUserActivity table with the IP address, form name accessed (frmPersonnel), and the date accessed. When you click the View Activity button you should see at least one record with this information. The validation and error display should work for entering data. All navigation and hyperlinks should work. Once you have verified that it works, save your project, zip up all files, and submit in the Dropbox. image showing computer screen: Please enter first name image showing computer screen: Please enter last name image showing computer screen: end date must be greater than start date NOTE: Make sure you include comments in the code provided where specified (where the " //Your comments here" is mentioned) and for any code you write, or else a five-point deduction per item (form, class, function) will be made. You basically put two forward slashes, which start the comment; anything after the // on that line is disregarded by the compiler. Then type a brief statement describing what is happening in the following code. Comments show professionalism and are a must in systems. As a professional developer, comments will set you apart from others and make your life much easier if maintenance and debugging are needed.
