Problem with COM+ component

I am writing my first COM+ component, to provide authentication on our intranet. The following code produces an "Automation error - library not registered":

Public Function IsAuthenticated() As Boolean

   Dim objContext As ObjectContext
   Dim objRequest As Request

   Set objContext = GetObjectContext()
   Set objRequest = objContext.Item("Request")

   ...

   objContext.SetComplete
End Function

at the "Set objRequest" line. I've included the COM+ Services Type Library and the Active Server Pages Object Library in the Project|References...

Any idea what's wrong?

Not 100% sure but I have a feeling that it may be related to the binding.

At present you using early binding which may mean that your types are not recognised.

Try using late binding and see if you get the same error..

If you need examples let me know and I'll try and knock something up..

Are you running this in the VB IDE? Unless you configure it very carefully, VB will return nothing for GetObjectContext because it is not running in COM+ so has no context. If you are developping on a Windows 2000 machine, it is possible to debug a component under COM+, and so get the context, but I don't remember where I found the article that explained this. Anyways, try placing a msgbox before and after that line, compiling it, and then running it under com+.

>Beeblebrox - yup it's running in the IDE. I added in a MsgBox before the problem line, and that pops up no problem. It still goes on then to fail at the usual place with the same error as before.

The annoying bit is I'm following the code samples in an O'Reilly book (Developing ASP Components) and it *still* doesn't work.

I feel an increase in points awarded coming on...

OK, solution found here

The short version is that the component was registered with Component Services, which conflicts with the VB IDE. Unregistering the component fixed the problem.
