rtn=GetDeviceCaps(prt_DC, RASTERCAPS)
IF rtn<>0 THEN
bitmapdc=GetDC(bitmap.Handle) ' THIS FAILS !!!
IF bitmapdc<>0 THEN
' Do a straight copy.
'Blit_BitMap(0, 0, 300, 200, bm_DC, 0, 0, SRCCOPY)
' Stretch the bitmap.
'Stretch_BitMap(0, 0, 400, 400, bm_DC, 0, 0, 200, 200, SRCCOPY)
rtn=ReleaseDC(bitmap.Handle, bitmapdc)
IF rtn<>0 THEN
ELSE
showmessage("ReleaseDC failed")
END IF
ELSE
showmessage("GetDC failed")
END IF
ELSE
showmessage("GetDeviceCaps failed")
END IF
I implore the powers of our lord Guidance for help & pity !!!!!!!!!
