could not get what your idea or requirement. plz elaborate with some example.

from the main form I want to be able to have an external program run inside that form.

eg,
I have a web camera program that I would like to be able to look like it is part of my main program.

So you click a button on the form and it loads the program inside the main program

I want to do it this way so that I can update the external program with out diving into the main program

After a lot of googling I think what i need is the OLE container.
am I right in thinking this
