Other Application Inside Own Application

Hi Peeps! To all gurus out there and newbies like me, this is for you. I just want to know how can I put other application inside my own application. Let's say the calculator. I want to call this piece of application and place it inside my own MDI form. I certainly have no idea of how to do this but I need to since it is being asked.

Thanks!

You have to use the SetParent api function. Take a look at this thread to find out how.
