Doesn't work?
At all?
Problems with colours?
Error message?
Give us a clue....
Using SetStretchBltMode with HALFTONE mode? If so:
Quote:
HALFTONE
Maps pixels from the source rectangle into blocks of pixels in the destination rectangle. The average color over the destination block of pixels approximates the color of the source pixels.
After setting the HALFTONE stretching mode, an application must call the SetBrushOrgEx function to set the brush origin. If it fails to do so, brush misalignment occurs.
This option is not supported on Windows 95/98/Me.
Stretchblt does not work at all. only the blank background of the second picture box remains after the stretchblt operation.
i have set the autoredraw property to TRUE. is it right?
i am not using HALFTONE.
i am using the last parameter as VBSRCCOPY. Tried VBSRCAND and VBSRCPAINT. Nothing worked. only got a blank screen.
Please help.
