Is there a way to access the version number I have given my app
in the Project Options ->Version Info page? What I'd like to
do is have the app automatically change the version number on my
"About" form so I don't have to remember to do it manually.
Thanks much,
-Terry

VFSCopyrightLabel->Caption=copyrightStr;

KillAry( versionInfo );
}
KillAry() is a template that calls delete[]
(but often don't). Presumbably there is a way to set this information
but I can't find it.

Many thanks! I massaged the code you posted to fit what I'm
doing, and it works perfectly.
I only needed to automatically update a few TLabels on my About
form when I change things in Options->Version Info.
Great stuff!
