DebugInfo - Version 1.0 This is a debug monitoring program. It will monitor all strings generated by OutputDebugStream and show them catagorized according to the process ID of the process that generated the string. In addition, you can attach to a process and get all the other debug events (like thread attach/detach and DLL load/unload). You can save all the information to a file to load again at a later date. The complete source code (written as an example of using WTL) and an article explaining it is available.
