Running an application and keeping it inside my window

Hi

I need to create an MDI application that can run other applications like MSWord, MSOutlook, etc (the end user will define the applications, so I dont know the list of applications my program will run). The problem is that the applications do not have to show in the taskbar but they must be inside my MDI Form.

I downloaded an example that uses the API function SetParent, but I have some problems when I run applications like Mozilla Firefox. The documentation states that the SetParent function should be used only with windows of the same application.

Can I use another function to complete that task?

Thanks.
