Any way to get the address of a memory DC?

[fabiosa]

I have looked, but I cannot find if there is any way to get the address of the memory set aside for a newly created memory Device Context (with a bitmap in it).

I need to copy the memory into a local array to allow me to change pixel values manually and the copy it back into the original Device Context memory space. I have found that even SetPixelV is far too slow to carry out the operations at any decent speed.

Any help would be great

You could look to get the bitmap bits with GetObject API call and once modified call SelectObject to select it back into the device context.
