970/*
971When I started programming with Visual C++ v4.0, I missed one of my favorite
972tools -- DBWIN. Finding the code for a simple debug trace utility, DBMON,
973on MSDN was a step in the right direction, but it is a console application
974and thus has limited features and extensibility. DBWIN32 is my creation
975to solve this problem.
976
b07135ba 977The code is essentially a merging of a stripped down version of the DBWIN code
a0a302dc
JS
978from VC 1.5 and DBMON.C with a few 32 bit changes.
979
b07135ba 980As of version 1.2B, DBWIN32 supports both Win95 and NT. The NT support is
a0a302dc
JS
981built into the operating system and works just by running DBWIN32. The Win95
982team decided not to support this hook, so I have provided code that will do
983this for you. See the file WIN95.TXT for instructions on installing this.
984
985If you have questions, problems or suggestions about DBWIN32, I welcome your
986feedback and plan to actively maintain the code.
