We need to use a previously developed .NET application with a existing
VC++/MFC application. Idea is to convert the .NET application to an ActiveX
control which can be inserted in the ActiveX Container Application. However
there seems to be no way to do this.
A .NET component without a GUI can be used by COM application, but there is
no mention of the control with a GUI. Anyone has any idea how to do this?

the supported mechanism is to host the control inside IE and then host IE in
your app
for the unsupported way see adam nathan com interop book p 471

Hello Ramchandra,

There is some code and an example at:
http://msdn.microsoft.com/msdnmag/issues/03/03/windowsforms/
"Managed Controls in Unmanaged Hosts"

the drawbacks are:
- the host has to be compiled as managed code
- this works with VC++ 2003 or newer
- it has to use MFC

But it seems to work. I could reproduce the example with my own C#
windows forms control.
