Word control focus issue

[Klein]

I have an application which can load ms word documents and save them. The
application has a main form with a file menu, an edit menu and a tool bar. I
have a DocumentControl(usercontrol) defined which handles loading the word
document into itself. The flow of events are as follows:

Main Form -> New -> Creates an instance of DocumentControl -> Loads Word
document into DocumentControl (by passing itself as a window handle).

The new document loads into the DocumentControl and I am able to see the
word document and play with it. The issue is that when I click on the
DocumentControl window, I lose focus on the main form. This is a problem
because when I select some text in the word document, and I go to Edit Menu
to do some operation, I lose focus on the DocumentControl window (and so the
text gets dehighlighted). This looks very ugly to the user as he would think
the text was not selected.

So, can anyone please let me know how to load the document in a new window
but not lose focus from the main form?

Thanks a lot.
