I haven't quite kept up with this Win32 feature.
Using RB2006, is there a built-in way to stop multiple application
invocation ...
Sure is...
In App.Open:
// appmutex As Mutex is a property of App
appmutex = new Mutex( "YOUR APP'S UNIQUE IDENTIFIER STRING" )
if NOT appmutex.TryEnter then
// Already running...
Quit
end if
In App.Close:
if appmutex <> Nil then appmutex.Leave
I also set a flag if TryEnter fails, and return immediately from
App.OpenDocument if that flag is set. I'm not sure that's actually
needed but at some point I guess I decided it was. I used to use
declares for this so the way I go about it may just be a remnant of
that old code - testing the Mutex again in OpenDocument should do
just as well.
