Log in to the Citrix iLab site as you did in the previous week's iLab. The Microsoft Visual Studio 2012 icon should
already be displayed on your Citrix main menu page. Click the Microsoft Visual Studio 2012 icon to launch Visual
Studio.
You should see a screen similar to the following.
STEP 2: Create Project

(a) Pull down the File menu and select New Project . . . .
(b) In the New Project dialog, ensure that in the left column, under Templates, Visual Basic is selected; and that in the
center column, Windows Form Application is selected. In the Name field at the bottom of the dialog, enter
PaymentCalculator. Click OK.
(c) A project with a blank form should be displayed, as shown below.
STEP 3: Rename Form

(a) In the Solution Explorer pane on the right side of the screen, right-click on Form1.vb, select Rename, and change
the name to PaymentCalculator.vb. Press Enter after entering the new form name.
(b) Click on the form in the center Design pane to select it. In the Properties pane at the bottom right of the screen,
change the Text property of the form to Lab 2 Your Name where Your Name = your full name. Remember, you may

(a) Check that the Toolbox is displayed at the left side of the screen. If it is not, click the Toolbox tab at the center left
edge of the screen to expand the Toolbox, and click the pushpin symbol at the right side of the Toolbox title bar to pin
it open.
(b) If necessary, click the Common Controls heading in the Toolbox to expand it. Drag four Label controls, three TextBox
controls, and one Button control from the Common Controls area of the Toolbox onto the form, and arrange them on
the form as shown below.
(c) If you received an error message, or if your application did not work correctly, apply the methods for finding and
fixing programming errors described in the reading assignment to debug your application. Post in the Q & A Forum or
contact your professor for assistance if needed.
(d) When your application runs and works correctly, capture a screenshot of the form showing the input and output
values given above. Remember, use Ctrl+Alt+PrintScreen to capture a screenshot. Paste your screenshot image into
a Word document. Select and copy your code for the button-click event and also paste this into the Word document.
Save the Word document as Lab2YourFirstLastName.docx (where YourFirstLastName = your first and last name; e.g.,
JohnSmith) and submit it to the appropriate Dropbox
