Re: Problems with "LastChangedRevision" keyword

Use svnversion.exe (part of the standard Subversion set of tools) or
SubWCRev.exe (from http://tortoisesvn.tigris.org/download.html). Use
either these tools as part of your build process to change a value in a
source file to the current revision number of your repository.

Info on SubWCRev is at
http://svn.collab.net/repos/tortoisesvn/trunk/doc/source/en/SubWCRev.txt
