thanks for your help. I found the doc files you mentioned, and hiding my
program from taskbar works well.

I could't download the mentioned unit for ShellNotifyIcon ("unknown
server"), but finally decided I do need a program window, anyway ;-)
(although one in "toolwindow" style)

...which leads to my next question:

- I can extract a program's icon by using the ExtractIcon() function.
- I can paint this icon by using DrawIcon() function - but then it's
  drawn in the icon's original size (16x16 or 32x32).

How can I scale this icon and draw it in 8x8 pixels?

Currently I'm doing the following in the wm_paint section of function
(ps is a paintstruct, r a rect)

	dc:=BeginPaint(hWindow, at ps);
	GetClientRect(hWindow, at r);

Sorry, I'm a complete newbie to Win32 gui programming...

Thanks for your help!
