pre build event

[Dirtydevil]

My problem is with pre-build events. I have a custom resource compiler that receives as input a directory name, then it compiles all custom resource files in that directory and generate a header (if different from the previous version). So I want my visual studio to ALWAYS run that command line, don't matter if it thinks the project is up to date... I've tried several things, but nothing works properly. The pre-build event never works right because it thinks the project is up-to-date and don't execute the pre-build.

Any help would be great on that
