To code this app using Visual Studio .NET ...
Start Visual Studio .NET and select the "ASP.NET Web Application" Template. I recommend testing it on your localhost IIS server. I typed over the "WebApplication1" part of the name to give it a more meaningful name. You can see how the bottom part of the "New Project" dialog screen from Visual Studio .NET should look in the illustration. You might see a window flash on your monitor that tells you that your application is establishing a connection with IIS.
Visual Studio will open and display a blank web page in "grid layout mode". Make sure the toolbox is displayed and double-click or drag and drop a Label, Textbox, and Button control onto your form. I changed the Text property of the Button to make it more appropriate. Then double click the Button control to open the code window with the initial code for the Button already entered. Then enter the one line of code you need to transfer a the value from the Textbox to the Label.
Label1.Text = TextBox1.Text
It's almost exactly like regular VB.NET coding so far!
Finally, simply click the run icon, select "Start" from the Debug menu, or press F5 to run your app. Your default browser should open at this point with the form you just designed displayed. When you enter something in the textbox and click the button, the same text should display in the label control.
If everything worked great, we're ready to tackle something a lot more real, the CalcPad Web User Control!
