problem with the CSingleDocTemplate class.. HELP

hi !
i have a problem with the CSingleDocTemplate class..
in the InitInstance() function, after ProcessShellCommand(...) i do some more processing, but i want to hide the window created after i call ProcessShellCommand(...)
the problem is that i cannot hide the window (even if i hide it after i call ProcessShellCommand(...) it is still making a flash).i want to hide it, because i need to create it, but after i create i do some more processing that takes some time, and i don't want to see that nasty looking window in background...
i think that is something in PreCreateWindow, but i'm not sure what style to use, and if that is a solution.
thanx !

Is it nasty looking because you do processing?

If yes the best guess is that this processing does not allow for window update while idle, since you are in some kind of a loop.

If you allow idle processing your application will have time to repaint. It is undesirable to hide window since user may think application never started.

You can use workers thread to process data or use local message loop.

Search this forum for many examples how to allow idle processing.

thanx but i already solved the problem...
i had a splash screen as topmost and in back i have the window exactly the same size as the image
thanx again !
