i m making Paint..i need memory device context i did it but it doesnt work did like daT static int i=0; if(i==0) { memDC.CreateCompatibleDC(pDC); i++; } pDC->BitBlt(20,10,436,364,&memDC,0,0,SRCCOPY); if i draw line i call invalidate it repaints so wht i draw in my device context i also draw in mem dc but it doesnt work???

you need to select the bitmap into your mem DC by SelectObject(...) function.

i tried but it gives assertion failure

there are million of samples in VC disk. try to search the function you used inside these samples. VC samples are first place to go for learning something new. when you test your functions (calling process), be careful to find which function doesn't work.
