regsvr32 question

[Alain Dekker]

I would like to create my application on a CD for distribution. One problem
I have is that a DLL must be registered on the system before the application
will run. I would like to determine if that DLL is registered before
running:

regsvr32 MyDLL

Is there any way to determine if the DLL is already registered and if so NOT
register the DLL?

Thanks,
Alain

Two obvious choices. During install, instantiate the control and it that
fails... or check registry keys set during install.

AFAIK, there is no harm in registering multiple times if all you're doing in
your DllRegister() function is adding registry keys. Adding keys/values that
already exist is harmless. Hence, there's really no reason to check.
