Bring anothe app to the front and an "Inside Application.Run" question

I tried the code at the end of this note although

I didn't think it would work since

without and "Application.Run.."

I'm thinking there is no message loop

as I had found this on the internet:

This is a Win32 message (or wait loop)

while (GetMessage(&msg, NULL, 0, 0))

{

TranslateMessage(&msg);

DispatchMessage(&msg);

}

but in .NET, Application.Run is used instead,

it calls those same functions internally.

Some explanation of what is going on would be appreciated!

========================

What I need to know for my code is:

How to make another process come to the front.

I'd ask in the message box if I should bring the other app to the front.

If I can't bring it to the front can I flash it's title bar?

========================

THANKS



///

Using mutx As New Mutex(True, "App", mutexWasCreated)

If Not mutexWasCreated Then

MessageBox.Show("Can Not Start App", "App is already running",
MessageBoxButtons.OK, MessageBoxIcon.Exclamation)

Return 1

End If

Internally, the API function MessageBox is called. It is a modal dialog box:

Read the 6th paragraph, stating that the system starts its own message loop.

I'd need another way to find the handle of the other process since I change
the MainWindowTitle depending on what the user is doing.



Thanks
 
That was interesting.
Especially the comments about dialog box owners.
I don't think I've been specifying the owner.

thanks
