hi , all
This is driving me crazy , I use msgbox method in .net 2.0 environment and
it is running fine on my IIS (Windows 2000) until today. The error is like
"Showing a modal dialog box or form when the application is not running in
UserInteractive mode is not a valid operation".
I just do not know what I did wrong to cause the problem , maybe
installing some 3rd party aspx control ? I search for the answers on
Microsoft.com but no one has clue about how it happen and how to fix. On
local machine using Virual Web Developer 2005 , the msgbox method is running
fine , but it get error after moving into IIS server.
Someone pleaes help
Thanks,
Henry
 
You can't use MessageBox in ASP.NET. You don't have any graphical user
interface, so there is nowhere that you can display the messagebox.

If you were allowed to use a messagebox in ASP.NET, it would pop up on
the web server where noone would see it, and IIS would hang indefinitely
waiting for someone to click it.
