MessageBox in C# - errors

[Zeba]

Hi guys,

I gave the following code in the page load function of one of my
codebehind pages :

if (!string.IsNull OrEmpty(keyword ))
{
System.Windows. Forms.MessageBo x.Show("Got your keyword!!");
SearchByKeyword ();
}

I also included the reference for System.Windows. Forms, but I when I
try to view the page I get the error :

System.InvalidO perationExcepti on: Showing a modal dialog box or form
when the application is not running in UserInteractive mode is not a
valid operation. Specify the ServiceNotifica tion or DefaultDesktopO nly
style to display a notification from a service application.
What does this mean ?

Thanks!

you can't show messagebox in a web page. use Response.Write( "bla bla");
instead.

So then in what context would you use

System.Windows. Forms.MessageBo x.Show("sometex t");

Thanks!

Zeba,

Also, you don't have to write on the page if you don't want to. You can
insert text into the page which will call the Javascript function alert (on
the inherent window object exposed by the browser) in order to show a
messagebox on the client.

Hope this helps.
