I don't know. You should possibly post your calling code.BTW, what was the
CoCreateInstanceExreturn value? :)If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler. -- Alfonso the Wise, 13th Century King of Castile.

Fine. Is your server machine name
"servername"(or simply is the name in your real code correct? What about thehr(theCoCreateinstanceExreturn value)? And what aboutqi.hrvalue? :)If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler. -- Alfonso the Wise, 13th Century King of Castile.

Hi...I have another doubt..In case of testing both client and server on the local machine I have used this include statement... #import "..\FileServer\FileServer.tlb" using namespace FILESERVERLib; But, When testing the server on the remote machine what kind of import statement Should I give..? Thank u...

The import statement is used, on the client side, to build the client itself. It has nothing to with the testing phase (i.e. use always such statement to build the client and then forget about it...) :)

Hi.. I tried the code.. When I'm trying to create an instance on the remote machine I get ACCESS DENIED error.. I have the security permissions for the DCOM though.. Thank U...:confused:
