alternatives to SetPixel()

[peterworth]

i want to create an array of rgb values and then draw them with a CDC. i assume the best way to do this is with BitBlt, but this requires a CDC to copy from in the first place. how do i create a CDC with the values in my (2D) array?

I believe you could create a bitmap from your raw data and simply select it with a DC, but I've never done that myself.

why do you need an alternative for SetPixel?
i think setpixel will do the job...

because its very very slow (1024 x 800 = a lot of function calls)
