901 | /* | |
902 | When I started programming with Visual C++ v4.0, I missed one of my favorite | |
903 | tools -- DBWIN. Finding the code for a simple debug trace utility, DBMON, | |
904 | on MSDN was a step in the right direction, but it is a console application | |
905 | and thus has limited features and extensibility. DBWIN32 is my creation | |
906 | to solve this problem. | |
907 | ||
908 | The code is essentially a merging of a stripped down version of the DBWIN code | |
909 | from VC 1.5 and DBMON.C with a few 32 bit changes. | |
910 | ||
911 | As of version 1.2B, DBWIN32 supports both Win95 and NT. The NT support is | |
912 | built into the operating system and works just by running DBWIN32. The Win95 | |
913 | team decided not to support this hook, so I have provided code that will do | |
914 | this for you. See the file WIN95.TXT for instructions on installing this. | |
915 | ||
916 | If you have questions, problems or suggestions about DBWIN32, I welcome your | |
917 | feedback and plan to actively maintain the code. | |
