Usage of Proxy / Stub dll

I am new to COM technology..
I am accessing a function in VC++ COM EXE from VB...by passing the Arguements as Variants (out parameters).I am creating the Safearrays and assigning that to Variants And all Went fine..SOme times i am Getting the Values in my VB Client and some times i am not getting the values....Its showing Empty...
I have not Generated any Proxy Stub Dlls...
Is there anything to do with Proxy/Stub dll...If yes How its affecting the client program?

COM Automation data types (including VARIANT and safe arrays) never require for custom proxy/stub dll, because universal marshaling mechanism takes care of them. So your problem is something or somewhere else.
