Zitat von DeddyH:

Und nicht vergessen, die Region nach Gebrauch mit DeleteObject wieder zu entsorgen

Leider falsch!!!!!!!

Zitat:

After a successful call to SetWindowRgn, the system owns the region specified by the region handle hRgn. The system does not make a copy of the region. Thus, you should not make any further function calls with this region handle. In particular, do not delete this region handle. The system deletes the region handle when it no longer needed.
