Hi Andre -

I'm not a real expert on interop stuff, but I'd suggest running
aximp.exe or tlbimp.exe to generate a wrapper assembly from the
dll that implements the WebBrowser control. The wrapper assembly
should expose everything in a way that Python will be able to use
it.

Then you should be able to instantiate the control via the wrapper
assembly from Python (or from C# for that matter), set it as your
control property and drive it from Python.

I'm guessing that VStudio.NET is using some kind of shortcut
involving a RCW or something when you drop a control onto a form
in the gui.

Hope this helps!
