Hi All,

I am facing a little problem where I have a third party DLL which has exposed a dialog box Window. I want my form to have this dialog as one of its tab and not as a popup.
The problem is that the Dialog is inherited from

public class CThirdPartyDialog : Window, IComponentConnector

and my Own application is a simple Form application inherited from

public class PersistingForm : System.Windows.Forms.Form

. And Some how I am not able to figure out the way I can have the dialog box added as a control in my form class object.

Thanks for you help.

Can you access the source code of the 3rd. party Dialog ? Is the class sealed, or can you sub-class it ?

Depends.. If needed I can but if possible I want to access it as it is. But, if you know the solution of how to go about editing the source code then kindly give me some pointers on it ... I think its sealed ..

If the class is 'sealed' then you can't sub-class it. The problem here, I think, is that the dialog must, after all, serve some purpose in the 3rd. party control, and you will need to duplicate not only the UI to make it a UserControl or whatever, but also its functionality in the 3rd. party control. Unless the dialog's purpose is very simple, and its functionality easy to simulate, then you need access to the source of the complete 3rd. party control ?

You are right. Also, you could note that the 3-rd party dialog is written for WPF while the host application is in System.Windows.Forms. This is more difficult problem. Such interoperation is possible, but with modal dialog...

Excellent point SA !

Very well said SA. I have already implemented the functionality by having it as modal Dialog ... but now I was looking for ways to make UI look even more consistent and the best way I could think was to make it as a part of a dockable panel in my own application ..But, now I think that is a far fetched idea. I think we will have to live with that implementation for now.
Thanks for the help anyways.
