Hi All:

I am running 2 instances of VFP to simulate a file sharing problem. When instance 1 says:
USE foo EXCL
This works in instance 2:
	TRY
		USE foo SHARED
	CATCH TO ww
		MESSAGEBOX('Problem!  You got error # ' + ALLTRIM(STR(ww.errorno)))
	ENDTRY
HOWEVER when instance 1 says:
USE foo
flock()
the 2nd instance just hangs with the following message in the status bar:
Attempting to lock... Press <esc> to cancel
How can I handle that situation gracefully with TRY..CATCH? I need this since the other system seems to be doing something like flock() and there's no way I can get the user to change the program.

Thanks,

Yossi
