Hello:
I have seen discussions about this at various times, but I have
not ever seen details.
You have an app which might be updated and want to have that
happen automatically.
In my case, it is a VFP .exe, and I wrote a program to handle
that years ago.
What about if the startup program needs to be updated? Since
there is a change (the first since) in that, I wanted to write a
version that would update the update program, too. Somehow, it did
not work. And since there is less debugging information available
when debugging a .exe, I ended up giving up on it after some trouble.
My thought was to have two programs:
cbs2run.exe would check cbs2run2.exe if it needed updating (and maybe
update), check cbs2.exe (the app) if it needed updating (and maybe
update), then run cbs2run2.exe.
cbs2run2.exe would check cbs2run.exe if it needed updating (and maybe
update), then run cbs2.exe.
The reason that I had two programs is so that cbs2run.exe would
quit running and be overwritable. Even inserting a 5-second pause
before trying to overwrite cbs2run.exe in cbs2run2.exe did not
work. I got some very inconsistent and confusing results.
Was I overlooking something? If so, what?
Sincerely,
Gene Wirchenko
