Hi, I try to access the QuickTime COM/ActiveX DLL file, QTOControl.dll
in my VC++ codes as follows:
HINSTANCE OTOControlLib = LoadLibrary("QT OControl.dll");
But how do I access the methods in the dll file?? The problem lies in
that QuickTime did not provide the .h or .lib file for the DLL file??
Any solution??
Thanks alot

Hi
GetProcAddress( OTOControlLib , "FunctionNa me" ) will return the
address of the function named "FunctionNa me" inside the DLL if it has
been exported by the DLL. But you must know the prototype of function
"FuncionNam e" in order to store and/or use the pointer returned by
GetProcAddress.
You can see the functions exported by a DLL using dependancy walker

Thanks for the reply.
I tried the GetProcAddress but what if the function name is input
parameter?? then how do I go about doing it?
Anyway I thought this is c++ programming.. m I wrong?? Cos I just
started programming in C++ and thought that LoadLibrary, GetProcAddress
etc are C++ programming syntax.
Sorry

It a C++ language group, we discuss the core language as defined by the
standard. Anything platform specific (DLLs for example) is of topic and
you'll get better advice on a platform specific group.

No, they're Windows API functions, accesible from any language that
supports them.
Try [comp.os.ms-windows.program mer.win32].

1. Are they only/mostly syntactic sugar (important as that can be)?
