GetDC error with workaround
lazarus / 34-Windows

GetDC fails with SIGSEGV on Window-handles belonging to Lazarus on
64-bit Windows 7 (and so might also fail on other Window-handles):

hdcSrc := GetDC(hWnd);

This error does not occur on 32-bit Windows XP. You can use GetDCEx as
a workaround:

hdcSrc := GetDCEx(hWnd, 0, 0);
