ICallFactory Interface doesn't exist

[ahsaputro]

I'm currently developing an Object using an Asynchronous interface, which needs an ICallFactory interface in order to do so.
ICallFactory is an Interface which needed to get an Asynchronous version of interface from an object.
But when I create code for ICallFactory interface, both ICallFactory and IID_ICallFactory are remark as an Undeclare Statement.
Did I miss something when I install my Win2000 advance server. If I did, can someone give me a hence ?
Thx

Check Objidl.h file in the include folder, for it's version.
You will see this comment, "File created by MIDL compiler version 3.03.0110".
If version is 3.03.0110, then ICallFactory is not supported.
Updated Objidl.h file, that contains ICallFactory, version is 6.00.0334.
Search for SDK that supports, Async calls, Or use Studio.NET,
that includes this Updated Objidl.h.
