Bring up a project, and this time let's build a simple interface with two text boxes, a button and a label. Go to View | Toolbox. Type tex in the Search Toolbox field, and drag two TextBox controls into the page. You will read a couple of values from the boxes, and then you'll just check whether they're empty or not.
Now, you will need to place a Button control that someone can click on. So again, in the Search& Toolbox field, type but and drag the Button control into the page. After that, place a Label control so that you have a place to display content, and add it into the page. Now you have a very simple interface. Your initial screen for this project should now look like the one shown in the following screenshot:
