It sounds like you're having trouble locating the IVsOutputWindow
interface. If so here is the information on that type
- Namespace:
Microsoft.VisualStudio.Shell.Interop
- DLL: Microsoft.VisualStudio.Shell.Interop
If the SDK is install on your machine the DLL will be located in the following directory
C:\Program Files (x86)\Microsoft Visual Studio 2010 SDK\VisualStudioIntegration\Common\Assemblies\v2.0\Microsoft.VisualStudio.Shell.Interop.dll
The top 2 directories may change though based on the operating system and version of the SDK you are using. If this doesn't work please let me know the SDK version you are using and I'll try and point you to the correct path.
