I am taking advantage of the recent FileVersionInfo to pull up the Version Number of the Executable at Run Time and display it for the User (who can then call me and say "Version 126.96.36.19934 crashed", and I can figure out which source this was). I take advantage of the Pre-Build Action to create the Version Number, taking the "Build" part from the Revision Number of the Project itself (since the Pre-Build Action gives me the path to the Project, this is fairly straight-forward).
However, in order to get the correct Build to appear in my Executable, I must build twice. The reason for this is that LabVIEW apparently reads the Version information before executing the Pre-Build Action, so my attempt to set it to the "correct" value is ignored until the subsequent Build.
Personally, I think it is illogical to have a "build Action" that silently takes place before the user-specified "Pre-Build Action", though there may well be a hidden "good reason" for this. I would like to request, therefore, that LabVIEW include a "Feature" that specifically allows the Pre-Build Action to include not only setting the Version Information (which it currently does) but allowing this updated Version Information to be used in the current Build. True, the work-around of "Build Twice, Use Once" works for me, but why should we need to jump through this particular (unpublished and unexpected) hoop?
