Comments

This function is the first step of a double buffering process. Call LDoubleBuffer::CreateHandle. If successful, your object will contain a double buffering handle that will be used throughout the double buffering process. When you are finished with the object, you must call LDoubleBuffer::DestroyHandle.

You may decide to call this function only one time for your application. If your application is MDI, and you want to double buffer several windows simultaneously, you may want to call this function once for each child window.
