[QUOTE="ziphnor, post: 78258, member: 14215"] In relation to the Auto zoom/crop discussed in this i need to be able to have MediaPortal call methods on the AutoCrop DirectShow filter(to set properties etc) through a custom interface. I dont really have any experience with COM and only a bit with C# Interop so im having a few difficulties. My DirectShow filter called AutoCrop already exposes an interface called IAutopCrop(this was autogenerated by the wizard that set it up). I have added a test method to this interface which i want to call from a test C# program. The interface (and related stuff) is declared like this(i simplified it for testing purposes the actual interface has more methods): On the C# side i have declared the following(based on how things are done in the MediaPortal DirectShowLib source): I can see in the MediaPortal source code that Marshal.BindMoniker is used to obtain IBaseFilter instances(which should be no different from what i am doing), but im a bit unsure as to what a 'moniker' is. I have the CLSID and IID GUID's (as seen above) but what am i supposed to do with them ? :) A little help, or a link to something that explains this clearly would be greatly appreciated. [/QUOTE]
