Hi : i have a set of dll that comes with the type lib. yes i can register them. however i have also do an object view on all the dll none of them contain the coclass referencing to the tlb no i can't create any object using VBA any other clue thanks

Hi i have actually posted this question in ATL section I have recieve a few tlb from a vendor . in these tlb there is only interfaces with no coclass at all. Can any body teach me how to use this interface or point me to a sample thanks PS: sorry for double posting, need it urgently

You can use this window api FindFirstChangeNotification it is easy to use, fast and low cpu consumption

If i were you , i did better choose to use VARIANT type in the parameter passing and cast it to safe array later This will make the COM more compatible with other languages

Hi all experts I have a few COM type libraries from a vendor . In the type libraries, there is only interfaces without coclass I am using visual c++, can any body show me a sample or teach me how to use the interfaces thanks
