I add tow Com libraries to my project, I can see their content with
intellisense, but when I instantiate a class contained in the library:

PDDirectLib.PDDatabaseQuery pDbQuery = new PDDirectLib.PDDatabaseQuery();

It raises an unhandled exception "Class not registered"



any idea???

The underlying COM object that the generated RCW (which is what you are
programming to when you add a COM Reference) must be registered in the
Registry through regsvr32 as it always has been. COM is COM and requires the
Registry. For a thorough explanation of all this please see my MSDN article

Yikes, well that's not a very intuitive error message now is it? -) Can you
say more about what kind of COM component it is? I could steer you down the
path of using the .NET Framework Interop command line tools like tlbimp.exe
rather than using the IDE (my preferred approach) but I am not sure you want
to go down that path.
