Activating Applications

I'm trying to get my application to activate itself, to produce the same effect as clicking on its button in the taskbar.

However, I've tried all of the following APIs, and none of them seem to achieve this effect:

SetActiveWindow
SetForegroundWindow
SetWindowPos
BringWindowToTop
SetFocus

How is this supposed to be done?

Did you try

::ShowWindow( hWnd, SW_RESTORE );
::SetForegroundWindow( hWnd );

? This probably won't work on win2k for security reasons. The call to SetForegroundWindow will be replaced by the sequence SetActiveWindow/FlashWindowEx. I haven't tried it myself, but the MSDN states a long list of conditions that need to be met in order for SetForegroundWindow to work as expected.

Hi fl0yd,

Thanks for the comment and the pointer to the msdn article, it explained everything.  You were right, when I used SetForegroundWindow I was just getting a taskbar flash (using XP).

I was actually trying to activate the app in response to a call from its Help File via a custom DLL.  So, now I get the DLL (under the foreground thread from the Help File) to activate it before I send the notification message.

Easy!  Thanks again.
