After posting my previous message I gave a thought to this point, you
are right I was linking to the Mozilla build XPCOM.LIB, hence it was

How and where do I get these Netscape files?

Do you mean I can avoid the nsCOMPtr? 
I have found that there exist a entry point for "XPTC_InvokeByIndex"
function, but I am unable to use this, can you please give me a sample
for this, I possible as I am really new for COM.

Thanx,
