Visual Basic Concepts Visual Studio 6.0 Turning Off Error Handling If an error trap has been enabled in a procedure, it is automatically disabled when the procedure finishes executing. However, you may want to turn off an error trap in a procedure while the code in that procedure is still executing. To turn off an enabled error trap, use the On Error GoTo 0 statement. Once Visual Basic executes this statement, errors are detected but not trapped within the procedure. You can use On Error GoTo 0 to turn off error handling anywhere in a procedure — even within an error-handling routine itself. For example, try single stepping, using Step Into, through a procedure such as this: Sub ErrDemoSub () On Error GoTo SubHandler ' Error trapping is ' enabled. ' Errors need to be caught and corrected here. ' The Kill function is used to delete a file. Kill "Oldfile.xyz" On Error GoTo 0 ' Error trapping is turned off ' here. Kill "Oldfile.xyz" On Error GoTo SubHandler ' Error trapping is ' enabled again. Kill "Oldfile.xyz" Exit Sub SubHandler: ' Error-handling routine goes here. MsgBox "Caught error." Resume Next End Sub For More Information To learn how to use the Step Into feature, see "Running Selected Portions of Y

I was getting an overflow error (read from the Err variable) in a routine that doesn't have an error trap but is called by a routine that does. I always thought error traps were only valid in the routine they were declared, http://stackoverflow.com/questions/736434/how-to-re-enable-the-default-error-handling-in-vb6 but it looks like an error in a subroutine can cause it to go to the calling function's error trap. So I turned off the calling function's error trap and found my overflow and all is well. But before I did that, I spent some time trying to find a programatic way to get VB to return to its default error handling inside that routine (so I wouldn't have to modify outside code to debug), but I couldn't. The only error commands I could find: On Error GoTo [label] On Error Resume Next On Error Goto 0 On Error GoTo -1 all turn on the manual error handling - is there a way to turn it off (back to the VB6 default)? vb6 error-handling share|improve this question edited Nov 10 '11 at 5:16 Yarik 1,56521729 asked Apr 10 '09 at 1:15 Fred Hamilton 3921621 add a comment| 8 Answers 8 active oldest votes up vote 9 down vote accepted This is explained thoroughly in the VB6 manual under Error Handling Hierarchy. On Error Goto 0 disables the error handler in the current procedure, not in the procedures that called it. If an error occurs in a procedure and this procedure doesn't have an enabl
three flavors: compiler errors such as undeclared variables that prevent your code from compiling; user data entry error such as a user entering a negative value where only a positive number is http://www.cpearson.com/excel/errorhandling.htm acceptable; and run time errors, that occur when VBA cannot correctly execute a program http://www.yiiframework.com/doc-2.0/guide-runtime-handling-errors.html statement. We will concern ourselves here only with run time errors. Typical run time errors include attempting to access a non-existent worksheet or workbook, or attempting to divide by zero. The example code in this article will use the division by zero error (Error 11) when we want to deliberately raise an error. Your application on error should make as many checks as possible during initialization to ensure that run time errors do not occur later. In Excel, this includes ensuring that required workbooks and worksheets are present and that required names are defined. The more checking you do before the real work of your application begins, the more stable your application will be. It is far better to detect potential error situations when your vba on error application starts up before data is change than to wait until later to encounter an error situation. If you have no error handling code and a run time error occurs, VBA will display its standard run time error dialog box. While this may be acceptable, even desirable, in a development environment, it is not acceptable to the end user in a production environment. The goal of well designed error handling code is to anticipate potential errors, and correct them at run time or to terminate code execution in a controlled, graceful method. Your goal should be to prevent unhandled errors from arising. A note on terminology: Throughout this article, the term procedure should be taken to mean a Sub, Function, or Property procedure, and the term exit statement should be taken to mean Exit Sub, Exit Function, or Exit Property. The term end statement should be taken to mean End Sub , End Function, End Property, or just End. The On Error Statement The heart of error handling in VBA is the On Error statement. This statement instructs VBA what to do when an run time error is encountered. The On Error statement takes three forms. On Error Goto 0 On Error Res
