Hi All,
I am using Montivision 3.1.5.0 with VS 2005 C#. I want to create a DLL application with Montivision Filters. But i am not able to load the filter using MVStmartControl. It is giving me an error "Object Reference not set to an instance of an Object".

How do i create a new instance of MVSmartControl.IMVSCFilterGraph.

Please help as i am new to Montivision

Thanks
Fairozkhan

The MontiVision Smart Control needs a window in order to be able to create an instance of the actual control object. It can be done by creating a window in the DLL and setting it to invisible.
