Source Code
COM Chat Compilable versions of the source code in Appendix B of the book.
YACL Yet another COM library. Contains the various macros and C++ classes described in the book.
IGlobalInterfaceTable Wrapper/Sample A simplification of apartment-independent pointer use.
HostHook A custom channel hook that allows you to find out the caller's and callee's network address.
APTSUR A custom surrogate that spawns distinct STA threads for each activation request.
Custom Moniker Stuff I worked with some friends on a custom moniker framework. Here is some of the 1st bits and pieces.
Yet Another COM Library (YACL) – Preview
This is my first drop. It contains a family of preprocessor macros that automate the boilerplate activities used in COM programming.
Please send comments and bug reports to [email protected]
The freshest drop is always available at http://www.develop.com/dbox/yacl.zip
Easily used without Wizard support
Easily kept in one's head
