I don't see the need for another thread. Your main thread can just open a window which shows the splash screen, then close it using either a timer, or at a specific point during initialisation ( i.e. just before the main app is ready to show itself ).

But if I show the splash using Application.Run(Splash); the function will return when the splash is closed, am I right? If it's that way, then I'm in a deadlock. That's why I resort the threads.

Why would you do this ? I'm talking about a modeless form being shown by your application, during startup. Sure, you can use a thread, it just seems like overkill to me.

Because using the same message pump for both the splash screen and the main application window might cause the splash screen to freeze if there is some heavy duty initialization involved.

How does a splash screen 'freeze' ? I guess if you move something in front of it ?

Yes. And if you intend to show some dynamic text in the splash screen window.

You could do all your initializing in the Main() function.
Something like as follows:
static void Main()
{
// Create splash
fclsSpash splash = new fclsSplash();
splash.Show();
// Create main form
fclsMain main = new fclsMain();
// Initialize this
splash.SetMessage("Initializing this.");
main.InitializeThis();
// Initialize that
splash.SetMessage("Initializing that.");
main.InitializeThat();
// Close splash
splash.Dispose();
// Show main
main.Show();
// Start application
Application.Run();
}

Hello,
I did solve my problem with the initial structure. So this is what I'm doing in Main():
1. Create Splash thread
2. Start Splash thread
3. Create Main Window Thread
4. Start Main Window Thread
5. Hide Main Window
The thing which I'm working now is to implement an event which will signalize the splash screen that main is ready and it should close itself and Main form should appear.

How do I check id MDI Form is activate?
|
|
|
|
|
//
// code in your MDI parent form (not tested)
//
public MDIParent() {
...
mdi = new Form()
mdi.OnActivated += new EventHandler(MdiOnActivated);
// ...or similar name of this event, I'm not sure
}
void MdiOnActivated(object o, EventArgs e) {
Form activeMdi = (Form)this.ActiveMdiChild;
...
}
|
|
|
|
|
oh - and if you want to check if MDI is active, just compare:
if (mdi == this.ActiveMdiChild)
// mdi is active
else
// mdi is inactive

Maybe it is printing outside the margins of the page.
Try: e.Graphics.DrawString(txtText.Text, fnt, Brushes.Black, e.MarginBounds.Location);

No joy. Tried it and get the same behavior. Thank you for the suggestion.

In working on a small C#.net program that starts another program via rundll32. This program performs an operation and then opens a IE page showing some results. I would like to be able to close this IE process after the WaitForExit() call.
Process proc = new Process();<br />
ProcessStartInfo processInfo = new ProcessStartInfo("rundll32.exe");<br />
processInfo.Arguments = Config.DLL_ARGUMENTS;<br />
proc.StartInfo = processInfo;<br />
proc.Start();<br />
proc.WaitForExit();<br />
I know how to get a list of processes running, but how do I know which was the IE started by my other proc. call??
Thanks for any help!

You'll have to get the list of processes, launch your .DLL thing and wait for it to terminate. Then enumerate the processes again, comparing the list to the one you have stored. You'll be able to find the IE instance that was launched then.

In addition to, or instead of this, you could have the page that's created and displayed have a particular title. The new IE window with the "[title] - Microsoft Internet Explorer" title will be the one you're looking for.

He can't change the title, since it's a seperate .DLL he's running using rundll32 that's launching the IE window, not his application.

How do you know its not a separate .DLL that he or someone he works with wrote? Anyway, the same idea applies if the title of the page is fairly consistent, whether or not he has any influence over exactly what it is. It's just a little extra insurance in case where two or more instances of IE appear in that same timeframe.
By the way, you might also have trouble in the case where an existing instance of IE picks up the page, instead of a new instance of IE being launched; this depends upon how the DLL is launching the page.
