There is no like shooting fish in a barrel fashion. You would take to search the registry for it in HKEY_CLASSES_ROOT. Rather than checking, yous tin can just re-register the DLL everytime using regsvr32. Re-registering doesn't harm anything.

You can search for the filename under HKEY_CLASSES_ROOT in the registry. That's not a guarantee that the DLL will work, simply it's meliorate than zero.

If you know the course name for the COM object contained within the DLL, you tin instantiate it using a tool similar Oleview (arranged with Visual Studio if y'all have that installed). Instantiating the object is a better test than searching the registry.

If you lot know the class proper name for the COM object contained within the DLL, y'all can instantiate it using a tool like Oleview (bundled with Visual Studio if you accept that installed). Instantiating the object is a improve test than searching the registry.

Sweet, thank you guys. I figured this was the only way.
