Hi All,

I have downloaded George's routine 'is_run32'. I have used it with no problems in programs that are running. Now I am trying to use it to block multiple instances of the calling program. In my main.prg I put this block long before I open any forms:

* This is a call to a function to check and see if this program is already running
exe_running = is_run32("Remote Process")

* If the Function found that this program was already running
* Block any multiple instances.
IF exe_running > 0
QUIT
ENDIF

"exe_running" always == 0. If I add a messagebox('anything') before that block. I always get the handle of the other instance.

My question is, must my '.exe' have some prior interaction with windows for the function to work? If so, is there a way to do it without user involvement? Or will this only work once the form has been loaded?

TIA
Mike
