#323 Getting TargetInvocationException with ActiveX control

[Alex Brunner]

We are using NUnit 2.2.0:

I am trying to test a form with an ActiveX control on it.
I use the MS Browser control.

When running a test which creates an instance of this
form I get an exception from the NUnit GUI with the
following message:

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** Exception Text **************
System.Reflection.TargetInvocationException: Unable to
get the window handle for the 'AxWebBrowser' control.
Windowless ActiveX controls are not supported. --->
System.NullReferenceException: Object reference not
set to an instance of an object.
