macro works fine if the person who runs it selects a range containing numbers before vba error number running the macro. But if the user selects something else—a chart embedded on the worksheet, for example—VBA displays the error message: "Run-time vba error handling display message error'436': Object doesn't support the property or method". The macro generates a run-time error and enters break mode because the For Each statement has to be applied to a collection or an array, and a chart object https://msdn.microsoft.com/en-us/library/5hsw66as.aspx is neither. (A range is a collection of cells, so For Each does work with a range.) Even though you can figure out easily enough what the error message means and what you have to do about it (try again with a range selected), the message might still be annoying. If you intend for this macro to be used by someone else, it’s definitely impolite to let that other user see such a message. http://cis.poly.edu/~mleung/CS394/f06/VBA/Debugging/runtimeErrors.html You can “trap” an error like this—that is, shield yourself and others from VBA’s run-time error messages—by means of an On Error GoTo statement. 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 in your program: On Error Goto label If a run-time error occurs, the On Error GoTo statement transfers execution to the errorhandling code. In the case of your LakhsCrores routine, the macro complete with error handling might look like this: Sub LakhsCrores() 'Catch run-time error caused by inappropriate selection On Error GoTo ErrorHandler For Each cell In Selection If Abs(cell.Value) > 10000000 Then cell.NumberFormat = "#"",""##"",""##"",""###" ElseIf Abs(cell.Value) > 100000 Then cell.NumberFormat = "##"",""##"",""###" End If Next cell 'Exit sub statement keeps execution from entering 'error handler if no error occurs Exit Sub 'Error handler ErrorHandler: MsgBox "Please select a worksheet range" End Sub Notice that the error handler goes at the end of the program, introduced by the label that appeared in the On Error statement. The label must be followed by a colon and must appear on a line by itself. An Exit Sub statement appears before the error handler. This statement terminates the macro when no run-time error occurs; without it, exe
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 acceptable; and run time errors, that occur when http://www.cpearson.com/excel/errorhandling.htm VBA cannot correctly execute a program statement. We will concern ourselves here only with run http://stackoverflow.com/questions/4558300/vba-displaying-the-standard-run-time-error-handler 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 should make as many checks as possible during initialization to ensure that run time errors vba error 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 application starts up before data is change than to wait until later to encounter an error situation. If you have no error handling vba 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 Resume Next On Error Goto

If a specific error, say xxxxxxx, occurs, then a MsgBox should be displayed. If another error occurs the standard run-time error handler should pop up. How can this be accomplished? Here is the example code: On Error Resume Next 'Line of code that causes an error here. If Err.Number = xxxxxxx Then MsgBox "Specific error message." ElseIf Err.Number = 0 Then Do nothing Else 'Some error other than xxxxxxx. 'This is the problem. Here I would like to display standard run-time error 'handler without causing the error again.

It's not the actual error message dialog that VB6 puts up; it's just formatted
