I would like to put the date the application was built somewhere in the application. Say the about box. Any ideas how this can be done? I need to do this for C# but I am als
You should be using version control - Subversion is free. Then you could include a number from the version control system that would unambiguously identify the source code used to build the app. A date won't do that. There are other advantages too.
EDIT: Nikhil is already doing all this. But for some incomprehensible reason he has been told to include the date as well. I'm going to leave this answer here anyway, for future readers of this question.
