We're going to create a very simple ASP.NET web page and then introduce a more complex one. The simple one will be just to make sure that you have the basics down before we dive into something real. It's easy to be confused about whether a specific program is giving you fits or whether you don't have the process of programming an ASP.NET application working at all. But once we get this one done, we're going to program the same CalcPad application featured in the article, Need A Four Function Calculator For Your VB.NET Project?, and not only that, but we're going to duplicate the ENTIRE thing by making it a Web User Control just like the original is a component user control so you can add it to a project with drag and drop efficiency just like the original!
But first, let's make sure everything works with a "very simple" application. The "FirstAboutVBApp" is actually the same textbox and button that we saw in part two of the tutorial, but let's extend it just a bit to actually "do something" ... we'll code it so it updates a value in a label with the same value typed into a textbox. Your finished application should look something like the illustration shown below.
