Here is how you fix that: Look for the definition of CopyBits. See that first
parameter? See its type? Determine what that type is, exactly, then make sure
you pass that type in to CopyBits.

For example, if CopyBits wants a pointer to a BitMap or PixMap, then what you
have looks like it might work, if it wants a handle to one of those you will
have to remove the * from your first argument.

When in doubt, look at the definition. Once you learn that, you are on the
road to learning to help yourself. There is no magic here.
