i am using DrawDIBDraw function to draw a large bitmap. As a result, the Bitmap is drawn for the fraction of a second and then it disappears. I am using following code .....
HDRAWDIB hdd = DrawDibOpen();
DrawDibDraw(hdd, hPaintDC,0,0,BITMAP_WIDTH,BITMAP_HEIGHT,& m_BitmapInfo,m_pBits,0,0,BITMAP_WIDTH,BITMAP_HEIGH
how can i solve the problem . why it disappears.
