strange error

[wessamzeidan]

Hi, I have an application with 3 forms. One is used as a splash screen, another as the main form and the third as a dialog form. I'm using the main procedure to launch my program. The program was working fine when I had no splash form, but when I added the splash form, I got a strange error.

 

The error occurs when I close the dialog form, I have a button on the form that closes it, it has this line of code

 

me.dispose()

 

When I click this button I get this error

 

'An unhandled exception of type 'System.Runtime.InteropServices.SEHException' occurred in system.windows.forms.dll

 

Additional information: External component has thrown an exception.'

 

and the program stops at this line

 

Application.Run(new splash)

 

Any one has an idea from where does this error come from????

Any imported (referenced) objects on the splash screen ?

No, the only thing I have on the form is a background image...

What happens if you change the "Me.Dispose()" to "Me.Close()"?

The same thing........

First, you don't want to use Application.Run(splash) - your app will close as soon as the splash form goes away. When you use Application.Run this way it means "run my app until the form specified is closed".

 

Search the forums for "splash" and you'll get a couple of good hints. The basic idea is to use Application.Run(frmMain) and from within frmMain show frmSplash. There are other methods to do what you want, I'd search the forums and read the help on Application.Run.

Thanks alot for the help. What I do is I show the splash form for 3 seconds, hide it and then show the main form. I use the closing event of the main form to call Application.Exit() to quit the program, I don't know if this is a good way of doing it.....

There was a sample around, where a splash screen was shown until the Application.Idle event was raised.

[Joe Mamma]

you can define a constructor for your main form that takes a form as an argument, in the Idle event of your main form destroy the splash

 

SplashScreen splash = new SplashScreen();
splash.Visible = true;
Application.Run(new MainForm(splash));
