>>>I have a Visual FoxPro robot program which is affecting by something. In some situation, I have a temporary file which become corrupted. When that happen, a dialog message appears on the desktop about the file being corrupted. However, my Visual FoxPro robot program continues to run and this is where the problem begins. While having this message on the desktop, the program can't execute certain things like being able to establish a SMTP connection. When I have this message, I really want my program to stop working.

If that dialog window has a fixed title different from any of the other windows on the desktop, use a timer in your robot program to monitor (with FindWindow API) that dialog window. Do whatever you want when you find the dialog window.
