Placing a .NET Form/UserControl inside a VB Form

I'm trying to place my own windows form or user control inside a VB Form.

My first attempt used the IOleWindow::GetWindow of the VB Form in order to get its handle. I then used Win32 API SetParent to place my .NET Form inside the VB Form.

Now the problem is that neither tab stops or accelerator keys work using this approach :/

Does anyone have a solution to this problem, or alternative ways of placing my .NET Forms inside the VB Form???

For reference, the VB Form implements the following interfaces that could provide a solution:
