How could you copy the contents of an HDC to a bitmap?

There is a good piece of sample code here that does just that (amongst other things).
I've used a similar technique before (many moons ago), but do not have the code to hand.

Off the top of my head I think you need to:
- Create a new DC compatible with the source DC. Call this the memory DC.
- Create a new bitmap of the correct size.
- Select the bitmap into the memory DC.
- BitBlt the source DC into the memory DC.
- The bitmap should now contain a copy of the source DC.
I'm at home so can't give you any code, so I hope this is enough to get you started. There is a good GDI section on Code Project.
