>VFP 3.0
>I'm using VFP as a wrapper aroung a DOS app. There are 2 users that will be able to access this program in a network. Prior to running the app, I alter the configuration file and change the printer type based on the user. Unfortunately there is a considerable time lag between the time the CFG file is altered and when the app actually loads the file. What is the best way to prevent the other user from altering that file in that interim?
