This documentation is archived and is not being maintained. Handling Run-Time Errors Visual Studio .NET 2003 Run-time errors occur after the application starts to execute. Actions that would generate run-time errors include: writing to a file that doesn't exist, attempting to open a table that is already open, trying to select a table that has been closed, encountering a data conflict, dividing a value by zero, and so on. At times, errors occur when users run your application. You can call your own error-handling routine by including ON ERROR. Typically, ON ERROR uses a DO command to run a routine that handles the error, as in: Copy ON ERROR DO My_Error If your application contains no error-handling routines when an error occurs, the application pauses and Visual FoxPro displays an error message with the following options: Cancel If a user chooses Cancel, Visual FoxPro immediately stops running the application and returns control to the system. Ignore If a user chooses Ignore, Visual FoxPro ignores the line that caused the error and continues to the next line in the program. For a complete list and explanation of Visual FoxPro error messages, see Error Messages. Tip Be sure to provide documentation to your users that describes the errors that they might see, and suggests ways in which they can correct errors. The following commands and functions are useful when anticipating and managing run-time errors. To Use Fill an array with error information AERROR

If I close that from, the talk is then visible on the next form.Is there a way to stop this and reset the talk option? RE: Advice on error handling MikeLewis (Programmer) 11 Apr 11 04:51 Are you saying you want TALK to be active, or that you don't want it?I assume you know that SET TALK ON or OFF controls the setting. And, also, that is it is scoped to the data session.
