- no Windows message "asking" for the current value of the integer - I don't
want to add this check and response to a number of apps
- not to the registry
- not to a file
- must be something I can implement not only in C++, but in VB as well

I'm already using a semaphore to determine which app is launched first
without any of the others running (and hence happens to set this value) and
that other apps subsequenly check the count of to see that they are not
first and in turn grab that value. I wish that there was a function where
you could easily create a global variable across apps and grab it via a
string label or something. I read up a bit on ATOMS and got e{*filter*}d at
first, then disappointed when I realized they weren't what I wanted.

Any thoughts?

Have a look at:
CreateFileMapping
MapViewOfFile
OpenFileMapping
UnmapViewOfFile

If you exclude this too, then nothing else is left ;-)

Create an out of process COM server that only allows one instance. In it
have your *global* variable. Just add the methods you need and away you go.

Actually, that ought to be very simple indeed. A mere 'follow the wizard'
exercise in VC and maybe even simpler in VB.

Any more...?

Oh, what about shared memory segment in a DLL that the apps load using load
library. The DLL would expose the methods for setting and getting the
integer value.

Nope, can't think of any more ;)
