I have to agree with Robert on this. If the exe is going to wander, I like
to tag it in version control, get the tagged version to a clean folder and
build the whole thing. Otherwise, what does the date and time really tell
you?

We're building a project in Microsoft eMbedded Visual C++ 4.0. In one

actual compile data and time of this version. I hope to be able to
tell exactly when an exe was made as different versions float around.
Problem is that the date and time in the executable only change if
that .cpp file was changed (as we usually use the Build Option instead
of the Rebuild All). I'm looking for a way to force the compiler to
always recompile this 1 file, even if it hasn't changed.
You can delete the .obj file, or even just change its modification
date (using a "touch" utility). I'm not sure how to automate either of
these; perhaps something in the Custom Build tab.
I try very hard to do a complete build for any executable that might
wander. That way I'm sure all changes have been incorporated and flags
such as __DATE__ are used.
