I have two questions conerning ActiveX programming. . .

1. I need an "=" operator for my control. How do I implement this?

2. I need to have an AddObject method in my control. How can I implement it to allow me to pass something like a CBitmap?

Thanks.

1. You cannot write an = operator for a control. COM does not allow operator overloading. In fact, COM does not have any operators.

2. CBitmap is not a COM object, which means you cannot easily pass it to COM. However, you can create a COM object whose purpose is to maintain a pointer to a CBitmap and whose job is to wrap around the CBitmap. I do not recommend you do this because there already is an interface that does something you want and it is called IPicture.
