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
