Hi Virusim,

It seems to me that you want to find out whether Table1 is opened somewhere
on the Net or not. So you can exclusively open it.
There is no direct way to do it. but you can make your own function

FUNCTION isopen(tctable)
LOCAL lcerror
PRIVATE liserror
lcerror = ON('Error')
ON ERROR DO myerrtrap
USE tctable EXCL
ON ERROR &lcerror
RELEASE liserror
RETURN NOT liserror
ENDFUNC

FUNCTION myerrtrap()
IF ERROR() = error number of file access denied (Sorry find it out)
liserror = .T.
ENDIF
ENDFUNC


Hope will help

Bye
Jayesh
