I used the original code and it worked from me.

-See the above post and try it with the case
and put the exist sub instead of the write line.

Hi Seth,

Thanks for helping me out here.

If I minimize all forms using the "Show Dekstop" button (in the quick
menu/quick start ... dunno what it's called in the english version of XP ..
it's right next to the start button in the lower left of the XP desktop
screen), the code doesn't work. It only works if I minimize the form itself.

Hope you get what I mean. :o)

Thanks!!!

Hi Seth,

I googled around and found out, that clicking the "Show Desktop" button,
doesn't minimize all windows, it just puts the "Desktop" infront of all other
running apps.

So now I have to figure out how to trap, when desktop is brought to the
foreground.

Any idea???

:o)

Thanks!

Yeah, I just tried out the full code too, and it doesn't even seem to
call the wndproc method. The shell command it is using is called
ToggleDesktop if that helps, but I'm not sure how to disable it. I'll
keep looking...

Maybe registering the sidebar as an app bar will solve the problem:
