Ambiguity in .dll file of activex project in registry

Question

0.00/5 (No votes)

See more:

I am working on a large piece of c++ code related to COM and ActiveX controls. In this I have one project compiling into .DLL file, and another project compiling to an .OCX file.
Now, when I look into all registered Automation objects on my machine, it shows that .DLL file registered as .OCX 32 bit file. and The project which was copiled to .ocx file is not there in list of registered Automation objects. I am unable to figure it out why its happening. Please let me know whether this behavior is correct. I am relatively new in working with COM objects.

What I have tried:

Tried to unregister and then register the dll file again with regsvr32 command. but still it is showing as .OCX 32 in list of registered Automation objects.

The registration is done by some reg-files which the IDL-compiler is creating. So must look into your project and modify them. By the way: an ocx file is a dll.

Change the GUID in the idl-file at all occurances!!!
