mutex

[Aleks Kleyn]

I designed vb application which I expected to run all time. to make sure
that application restarts when OS (assume win2000) reboots, I put this app
to statup folder. However I put attention that 2 or 3 copies of this app may
run at the time. To make sure that only one copy of app runs at the time I
added mutex class to block start of extra copy. However it does not help.
Probably different users during logon starts one more copy and mutex cannot
catch it. how I can prevent start of second copy?

Thank you, Aleks

Re: mutex

Anyway, your project properties has an item in "Applicatio n", called "Make
single instance application".

Yep. That can happen... Mutex's are per user session by default. Try
starting your mutex name with:

Global\

That should tell the mutex to be available in all sessions.

Re: mutex

I put this property. However different user making logon to the system can
start this application.
