UnhandledException question

S-Soft 666

Hi
My test app will email me any unhandled exception and I got this:

Showing a modal dialog box or form when the application is not running in UserInteractive mode is not a valid operation. Specify the ServiceNotification or DefaultDesktopOnly style to display a notification from a service application.

at System.Windows.Forms.Form.ShowDialog(IWin32Window owner)
at DevComponents.DotNetBar.MessageBoxEx
and many more lines...

Any idea where might be the problem? Any help is greatly appreciated :)

Probably you are trying to run the test program as a service or Web application, where the dialogs are not available.

Hi, thanks so much, I even don't know how to make/run a service or Web application (using php), never did that!
But I'm using Visual Studio .NET 2013 Pro and downgraded the project from .NET 4.5 to .NET 4.0 (maybe this downgrade caused something) :(
