Splash form stays open

I have a winforms app written in Vs2005 Vb.Net, The setiings are to Enable
the application Framework and I defined a splashform. Works fine if no
errors occur. I do a checking on the mainform load event to make sure that
my database connectivity works OK. If it does not, I give the user a warning
message, but he can end up getting an unhandled exception that closes down
the app, which is what I want in that case. However when the app shuts down,
the splash screen remains visible. I think that it is running in its own
thread and it does not necessarely close down when the app closes.
I think best thing to do is to use the application events, see if the
splashscreen is still open and if it is, close it down. However I'm at a
loss on how to code this, and maybe there is another better way, I was
looking also for a property somewhere where you could set the max time the
splash screen would remain loaded whatever the case. But I could not find
it.

Any help would be appreciated

What class are you using as your SplashForm? Can you post the namespace
and dll if you know it
 
Bob, I had a very similar problem and based on feedback I got from Microsoft
in the MSDN forums, it looks like you may be experiencing an confirmed bug
in the Application Framework. See here for details...

Basically, what I theorize is going on is that the Application Framework
will close the splash screen after it's done initializing the main startup
form. But if you cancel the creation of the startup form (say, because you
encountered a database error and want to shut down the application), the
startup form never completes its initialization. The Application Framework
is happily sitting there checking to see if the startup form is initialized,
finding that it's not, and happily waiting some more. Ad infinitum.

My solution? Unfortunately, because of this issue, I ended up not using the
Application Framework splash screen feature and managed the creation and
closing of my splash screen myself.

Yeah, you're right thats exactly what is happening.
You got a code snippet for managing the splash form yourself?
I would grately appreciate it.

And yeah I saw what they suggest as solution in the linkyou gave me, I'll
give that a shot also. THANKS.

With "Use SplashFrom" enabled, the SplashForm is the first object that
loads. If I want to check prerequisites (like OS) and do not want the
app to run if a condition is not met, I put that code in the
SpashForm:

Public Sub New()
If some condition is not valid then
MessageBox.Show("Condition not met")
End
End If
' This call is required by the Windows Form Designer.
InitializeComponent()
End Sub


In the above, the SplashForm and app never load if the condition is
not met.


If I want to test for a condition (like Internet connectivity), warn
the user, but not prevent the app from running, I do that in the
MainForm's Shown Event.

*scratches his head* Ugh! you're kidding right? *stomache churns* Glad I'm
finding this out NOW rather than later. I've just gotten done adding some
setup code in the initializing of my main form. It detects if the app has
been run before or not, and if not, runs the setup wizard... so... it sounds
like I need to shut off the application framework and do it the old-fashioned
way.

They way I'd like to see it run: splash happens. Main form loads and
displays, splash goes away, setup wizard appears. ... On the other hand, it
makes sense....
