VC++ COM DLL raising error 429 in Visual Basic 6.0

[huntjr]

I have created an MFC DLL in VC++ 6.0 with automation enabled and am able to compile it. The front end, Visual Basic 6.0, sees the COM info exported from the DLL (i.e., IntelliSense works). However, when I run code to create a new instance of a class in the DLL, it kicks back error 429 'ActiveX comoponent can't create object'. I did a little research and it seems to kick back that error when AppName.ClassName cannot be found under HKEY_CLASSES_ROOT. I did try registering the DLL using regsvr32.exe, and it succeeded.

I have not used VC++ before to create ActiveX DLLs. Any ideas?? Any help would be greatly appreciated!

1. If your dll depends on other COM DLLs make sure they are also registered with regsvr32.

2. To make sure that regsvr32 work fine just put the executable name regsvr32 in debug dsession and a breakpoint in DllRegisterServer and follow what he is doing.

3. You might have also some security problems, depending on what your ActiveX object is doing in constructor.
