Indeed, I forgot you could do that too instead of talking to the dispatch
interface yourself
Most C++ environments for Windows (say Borland C++) should have some utility
to read the control's type info (usually from type information embedded in
the control's OCX [DLL] or from a TLB file you provide externally),
similarly for anyother COM DLLs provided with Apple utility code for the
control, and generate wrappers that do the late binding stuff for you based
on that typeinfo.
So after that you should be able to use the code using pseudo-early binding
(have IntelliSense that is and some compiler checking, but binding to the
code at runtime and calling it as if it was scripting code).
If the control supports dual interfaces VC++ will make use of those for
early binding. Dual interfaces are IDispatch interface descendents that add
the same properties/methods as the dispinterface, but in COM way
(dispinterfaces are older, VB-era beast, IDispatch is a COM interface that
wraps their logic and one can extend from it their own interfaces to make
them dual, that is have both early - talking to the custom interface
entrypoints - and late binding - talking to the ancestor IDispatch interface
resolve/call by name standard entrypoint - support).
Try searching the QT-API list archive for "#import" (it's a special keyword
added at VC++6.x to support COM typeinfo so that you don't need to generate
wrappers). There should be a VC++ example for using the QT control posted to
the list by John Chromie now that I think of it
Cheers,
