Error Handler for "Switch, Retry, Cancel"

[brandewie7]

I am looking for suggestions on how to handle the error above. In my application, my code loops while the oia.xstatus <>0, and then waits for a specific string (waitforstring method). Occassionally the string never shows up (an unexpected error). After waiting for a while, an error shows up stating that the system is not responding(something like Switch, Retry, Cancel ?). The only way that I know how to exit the application is to CTL+ALT+DEL. Is there a err number for this? Or does anybody have any work arounds? Thanks for your help in advance.

I add a loop to a situation like that that waits only so long for the string. I use a do...loop where I get string up to 5 times. If I never get the string I expect after 5 iterations I have it stop. That way I have an out.

I use this code:

Do While .OIA.Xstatus <> 0
DoEvents
Loop

The "DoEvents" statement allows windows to execute the events that are in line. This keeps your system from "locking up" while in the loop.

I also then look to see if the screen changed in a successful query or an unsuccessful event. I then direct the code to the right place.
