I get nice results by using SendMessage with WM_GETICON. If that is invalid there is always GetClassLong with an index of GCL_HICON. HICON icon; icon = (HICON) ::SendMessage(hwnd, WM_GETICON, ICON_SMALL, 0); icon = (HICON) ::GetClassLong(hwnd, GCL_HICON);

thats it! thanks a lot! :o) hIcon = (HICON)::SendMessage(hwnd, WM_GETICON, ICON_BIG, 0); if(hIcon == NULL) hIcon = (HICON)::GetClassLong(hwnd, GCL_HICON); if(hIcon == NULL) hIcon = (HICON)::GetClassLong(::GetParent(hwnd), GCL_HICON); works - no just looking when hIcon is still NULL, if there is a ICON_SMALL :o) cheers and thanx vertex_x
