Frank,

If it registered correctly you'll see an entry like dllfilename.classname right in the HKEY_CLASSES_ROOT folder.

>Dave - Yes. I did a build for Multithreaded. But, I'm unfamiliar with REGEDIT didn't see anything in the Registry - but on my machine the ole Registry is pretty extensive. Shouldn't I see something there and under what heading? I wonder what might inhibit the registration process that occurs (theoretically) during the build... Frank
