>>>It is IMO bad practise to run from the network. If the workstation goes to sleep/hibernate, wake up, it will have lost the networkconnection and you'll have exactly this problem. It might not have to do with any DBF, but running a function or form or even displaying an image could cause this.

And that is what I said, the tables are most likely be a networked resource, so unless you are using a multi-tier approach (and I agree with you that it is a better approach but I doubt it is the most common approach used for FoxPro applications) where you do not have any tables open you already have the problem regardless of where your executable resides.


> Also you could try to toughen up your code by checking network connection before attempting to read/write - while not 100% proof, you might catch all lost connections up to this I/O point and only fail when loosing connection DURING I/O operation. Less chances of failure if net failure is not correlated with actual operation but caused by faulty wiring or flaky WLAN.

Same as before, if you are not using a multi-tier approach you most likely have the tables open all the time, for example you have a grid in your form and your tables are open as long as your form is open, so a network error will kill the application regardless of where your executable resides.
