And all the resources on google mention only this property
Since you know it all, - provide some examples re the activeX web browser control which show the use of a controlsource property. As far as links are concerned, I've already suggested you google more about the control. I'm not about to start doing your work for you.
And I did read the thread - the reference to the activeX control was one sentence
'There is another Active X browser control. One of the very few I use. It's that one you should look at'
I really don't care why two controls use the same dll. I'm quite sure other dll's get used by more than one control
I strongly recommend you do not bother answering this post, I really wouldn't want to waste any more of your time
