Hi Gene,

normally your Starter programm just runs the main program, after checking

for updates, and then quits itself. The starter cannot update himself, thus

another program / task has to do this. The easiest way would be to first

install a new main program, which checks the starter for version, and

optionally does the update for the starter program. Thus the two can update

each other :)

Betreff: VFP App Startup Program

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
