An Automatic Build Incrementer for VC6

Environment: Visual C++ 6.0

Visual Basic programmers have long had the ability to
automatically increment the build number each time the program was compiled. Visual
C++ programmers haven’t.

Several weeks ago, I started trying to find a way to do automatically increment
build numbers on each compile. I found several articles on the subject and some
source code but none of it did exactly what I wanted it to do, so I decided to write
my own incrementer.

Add the code to an existing macro
file or, if you don’t have an existing macro file, create one and add one dummy
macro so you can access the code snippet. Application_BeforeBuildStart() is a
Visual Studio defined event handler and although the code is in a macro file,
when you select the Tools|Macro menu item, you won’t see it, so you need at
least a dummy macro in the file to access the source code.

Note that these code snippets have been subjected to limited testing and
that you use them at your own risk. They work correctly in the test environment,
but you assume all risk for their use. I will not assume any
liability whatsoever for their failure to work correctly in your environment.

Please e-mail any comments, suggestions for improvement, problems, etc. to me.
