Thanks for the very helpful reply. This confirms what I had surmised. I'll check out the book too; I've run into many problems along the way that has been quite frustrating. I'm considering a re-write of the server side in Java for it's cross platform compatibility and so I'd like as much information up front during the design phase.
Thanks again.

The base class for the message map architecture is CCmdTarget .
And CWnd is derived from CCmdTarget .

So.......... When Include one these macros DECLARE_DYNCREATE and IMPLEMENT_DYNCREATE macros

No, those macros have nothing to do with a class' hierarchy. They are used for serialization, runtime information, and dynamic creation.

As David said, it has nothing to do with the message map.
These macros are the functionality implemented by the CObject class.

Sorry about responding so late as I am Sabbath Observant ??
I read the article that David pointed me to
When I saw the ON_THREAD_MESSAGE and the I noticed PostThreadMessage
I got the IDEA that an app does not need GUI objects to have a message
pump
BTW cann't seemd to find the TCP/IP notification message
for e.g. onSend... would it be WM_SEND I'll look around...

In terms of spelling or grammar?

Hi all...
I'm new to mfc programming, and have a question... hope you can help me
I have a program that make some calculation, the user input some numbers and press a button to start.
When he press the button, the program start the calculations, and shows the results in a Clistbox as it arrives.
The problem is that when I use clistbox.addstring, the results are not automatically show in the clistbox, instead the user have to wait for all calculations to finish to see the results.
What can I do to show the results as soon as it arrives in the clistbox, and continues to do the calculations in the background??
Thx...

Your UI looks frozen because the message pump is blocked doing calculations. You must do your calculation in a separate thread[^] and post a User defined message[^] to the main window and handle the message to update your list box.

Just an interesting aside - I ran into this a couple of days ago. Rather than define a custom user message for each individual action that must occur on the UI thread, I tried to do it the .NET way - define a single message, say WM_INVOKE, and pass a pointer to a member function as LPARAM when posting the message (like Control.Invoke). Unfortunately, C++ doesn't allow you to take a pointer to a member function of an instance object directly - you can get a pointer to a member function, but you'll have to track the instance yourself and then when calling, use the esoteric .* operator to invoke it.
I couldn't be bothered to write a separate struct to hold the instance pointer and the function pointer, so I ended up writing multiple user defined messages instead

After you do your addstring, call UpdateWindow:
clistbox.addstring(xxxxx);
clistbox.UpdateWindow();
Good luck.
