And what about "double-click"? not entirely sure (and no help on this pc) from the sounds of it, setting "Break in class module" would be the best idea (or F8 to see it in action

You can include a Resume statement within an error-handling routine if you want execution to continue at a particular point in a procedure. If no error handler exists in Procedure B, or if it fails to correct for the error and regenerates it again, then execution passes to the error handler in Procedure A, See ASP.NET Ajax CDN Terms of Use – http://www.asp.net/ajaxlibrary/CDN.ashx. ]]> current community chat Stack Overflow Meta Stack Overflow your For example, the following statement displays the error number and a description: Figure 12-6 shows an example of this.

Where the error occurrs in a called procedure, control is returned to the next statement which follows the last calling statement in the procedure containing the error handler.   Resume line: The specified line must be in the same procedure as the On Error statement, or a compile-time error will occur.GoTo 0Disables enabled error handler in the current procedure and resets it The DAO Error object and Errors collection.

There could be an error in your programming due to incorrect logic used in your code that prevents it from doing what you intended and may stop code execution, for example, The Err object maintains information about only one error at a time.

The statement must appear before the code that might cause a run-time error, and it has the following syntax, in which label is a name that identifies an error-handling section elsewhere Now when the user runs the macro after selecting a chart object, the user sees a polite message box instead of a rude run-time error message. If an On Error statement isn't working as advertised, you need to change one of your settings. 1. Identifying specific errors All errors are not created equal.
