Re: 8002801d: Library not registered.

If you used OLE View to view the typelibrary then it sounds like it should
be registered correctly. I don't know if jawin itself tries to load the
typelib too. Is there a stack trace to go with that exception?

Thanks,
Robert

Thanks for your response Robert,

Unfortunately I don't have access to the source for the dll, however, the
documentation for the component states:

"ICaptureServer2 is a COM component that implements a "dual
interface". It includes eight methods.
The original ICaptureServer interface and the ICaptureServer1
interface still exist and components created with previous versions of
the SDK will continue to work. ICaptureServer2 contains all the
methods of the earlier interfaces plus the GetBinaryScriptInfo.()
methods."

is there any way to verify that it is a dual interface without access to the
source?

I have used OLE View to view the interface... it looks like this:
**********************
Interface=
...
...
TypeLib=
l...{7398F007-2E17-46B5-A1AA-7FDF87EDB818}
l...5.0[PrimaryInteropAssemblyName] = IDWorks.CaptureServer.Interop,
Version=5.0.0.0 <http://5.0.0.0>, Culture=neutral....
l...5.0[PrimaryInteropAssemblyCodeBase]
=file:///C:/ProgramFiles/Datacard/ID
Works/BIN/IDWorks.CaptureServer.Interop.DLL
l..5.0[<no name>]=IDWorks Capture Server
l...0
l l...win32=C:\Program Files\Datacard\ID Works\bin\dccapturesvr.dll
l...Flags=0
l...HELPDIR=C:\Program Files\Datacard\ID Works\bin\

*******************************

the HKEY_CLASSES_ROOT\TypeLib\{7398F007-2E17-46B5-A1AA-7FDF87EDB818} key is
in the registry.

I had generated the code from the dccapturesvr.dll

and used:
ICaptureServer2 capSvr = new ICaptureServer2("DCCaptureSvr.CaptureServer");
to instantiate the class.

Using OLE View i have saved the type information as a .idl file I am
currently trying to find a way to compile this to a .tlb and register it
(just incase *shrug*)

Thanks again for the help
Kind Regards
Gordon
