ActiveX instead of DDE?

[ROOKIE]

How would you use ActiveX in place of the old DDE? I need to be able to access data dynamically(No passing data using files) with multiple applications. Someone suggested using a dll with global memory. Is this feasible?

DDE was an inter-process communications mechanism using the Windows message queue to exchange messages and data via global memory - ActiveX is a DLL interface - im not sure it makes sense to convert one to another architecturally. Why not stick with the message exchange architecture using WM_COPYDATA for the data - it may be difficult at best to "port" the asynchronous behavior of the DDE app using ActiveX or COM technology. Depends on the details i guess.
