1. The document discusses the design of DM and different approaches to message handling, including an Old Msg Selector, DLL Factory, and Object Message Factory.
2. Issues with the Old Msg Selector approach include difficulty in debugging, duplicative code across messages, and inability to reuse logic.
3. The DLL Factory approach separates message implementation from the server base but makes debugging harder.
4. The Object Message Factory approach uses a MessageProcessorFactory and base MessageProcessor class to better separate and reuse message handling logic.
The document discusses font settings for different windows in Visual C++ 6. It specifies font faces like Monaco, Verdana, and Fixedsys for calls window, output window, source window, and others.

This document discusses methods for finding and extracting substrings from a CString object in C++. It covers the Find() function, which searches for a substring within the CString and returns its index or -1 if not found. Using Find(), it demonstrates how to retrieve the substring to the left, right, or between two search terms. It also notes some considerations for Find(), such as it returning 0 when searching for an empty string.
