I coded my first asp form and attempted to display a text message from a component. The static text "Our component
says:" shows on the aspx page, but the text line from the component does not show. No errors are produced.

Can someone get me started down the right path with aspnet?

The two modules are shown below. The solution, less the .dll and .pdb files, can ge grabed at
http://psiprograms.com/Programs/HelloWorld.zip (about 16 Kb).

Thanks, Jim Holloman

Hi,
Putting the code within the "form" creates a server error >indicating
Click to expand...
that Page_Load()

You have two ways that you can write your server code : using code
behind (personally, i prefer it) or embedding the code in the ASPX file
(as you do) but you cant do them both.

Remove the code that attach the page load event (this.Load +=
EventHandler(Page_load)) and you wont get the above error. Or write
server side code in the code behind.
