Effect Change in Dll during Application running/execution.?

Vishal_K89 asked:

Hi All,

In my Application, comprising many COM-Dll's, I had added new class/interface/method, obviously, since, IID-CLSID changes, we need to register the Dll "abc.dll" using RegSvr32.exe "abc.dll", by closing the instance of Application.(pre-requisite) and replacing the newly registered dll's with the old one.

But my query, is it possible to effect the above scenario when Application is running(without the application been closed). ?

my understanding is, the Dll (Com-dll) is loaded at predefined base address in process address space, and when it is subjected to addition of interfaces/method, such dll needs to be un-loaded and re-loaded again to effect the modified change.

Is it feasible to add interface/method to COM-Dll for running instance of Application ?

Details:

VS 2008 IDE, Windows 7 o/s.

Thanks in Advance,

Regards,

VishaK_90
