Morning All
I need to write a DLL that can be called from an
asp page. From reading I understand that this DLL/class has to be registered on
the server. I am under the impression that it has to be a COM object in the DLL.
I have not done anything with COM before and am in need of a starting point.
There is a lot of functions in the MSDN for COM but I have found very little in
the line of what sequence they need to be used. A lot of examples that I have
found appear only to use a COM object but not many appear to create a COM
object.
I have seen CoCreateInstance called in some
samples. Is it called when creating a COM object as well as when using one?
If called when creating one, what is the value of REFCLSID rclsid (First
Parameter).
Secondly what is the easiest way to start this
project. Do I use ATL (another new one for me) or is it possible to do this
without ATL.. I would prefer not to use MFC in this project.
Waffle aside, what I am looking for is a place to
start to be able to take hold of this task and get started. Once going I am sure
it will be an interesting learning curve.
