message just like the standard error message which has a “Debug” button? up vote 12 down vote favorite 5 As usual, I create an error-handler using On Error Goto statement, there I put a few lines of cleaning codes and display the error message, but now I don't want to lose the comfortableness of the default handler which also point me to the exact line where

This code does what you want (please note the "line numbers") Sub a() 10: On Error GoTo ErrorHandler 20: DivisionByZero = 1 / 0 30: Exit Sub ErrorHandler: 41: If Err.Number <> 0 Then 42: Msg = "Error # " & Str(Err.Number) & " was generated by " _ & Err.Source & Chr(13) & "Error Line: " & Erl & Chr(13) & Err.Description 43: MsgBox Msg, , "Error", Err.HelpFile, Err.HelpContext 44: End If 50: Resume Next 60: End Sub When it runs, the expected MsgBox is shown: And now the bad news: Line numbers are a residue of old versions of Basic. The programming environment usually took charge of inserting and updating them. In VBA and other "modern" versions, this functionality is lost. However, Here there are several alternatives
with a predefined message. It returns an integer value based on the button clicked by the user, this helps to keep a track of the option selected by vba error message dialog box the user. VBA Msgbox can be mainly used for the below three reasons:

1. For displaying a message to the End user. 2. For graceful termination of a program in case of any unexpected vba clear error exception. 3. For deciding the program flow based on the user selection. Syntax of MsgBox function in VBA: The syntax of VBA Msgbox is as follows: MsgBox (Text_String [, buttons] [, title] [, helpfile, http://stackoverflow.com/questions/3911973/vba-how-to-display-an-error-message-just-like-the-standard-error-message-which context]) Here ‘Text_String’ is the message that you want the msgbox to display. The maximum length of ‘Text_String’ is 1024 characters. ‘buttons’ parameter specifies the type of buttons and icon that you want to be shown on the message box. It is an optional parameter. If you omit it then msgbox shows the default ‘vbOKOnly’ button. ‘title’ refers to the text displayed in the title bar of message box. http://www.exceltrick.com/formulas_macros/vba-msgbox/ This is an optional parameter. ‘helpfile’ is a string parameter that specifies the help file to be used for the dialog box. It is also an optional parameter but it becomes mandatory if ‘context’ parameter is to be used. ‘context’ is a numeric parameter that specifies the number assigned to the appropriate Help topic. It is an optional parameter but it becomes mandatory if ‘helpfile’ parameter is used. Different values of ‘buttons’ parameter in Msgbox: In VBA message box, ‘buttons’ parameter can have following values: Constant Description vbOKOnly It displays a single OK button vbOKCancel It displays two buttons OK and Cancel. vbAbortRetryIgnore It displays three buttons Abort, Retry, and Ignore. vbYesNoCancel It displays three buttons Yes, No, and Cancel. vbYesNo It displays two buttons Yes and No. vbRetryCancel It displays two buttons Retry and Cancel. vbCritical It displays a Critical Message icon. vbQuestion It displays a Query icon. vbExclamation It displays a Warning Message icon. vbInformation It displays an Information Message icon. vbDefaultButton1 First button is treated as default. vbDefaultButton2 Second button is treated as default. vbDefaultButton3 Third button is treated as default. vbDefaultButton4 Fourth button is treated as default. vbApplicationModal This suspends the current application till the user responds to the message b
the wrong time. The application may crash. A calculation may produce unexpected results, etc. You can predict some of these effects and http://www.functionx.com/vbaexcel/Lesson26.htm take appropriate actions. Some other problems are not under your control. Fortunately, both Microsoft Excel and the VBA language provide various tools or means of dealing with errors.

One way you can do this is to prepare your code for errors. When an error occurs, you would present a message to the vba error message user to make him/her aware of the issue (the error). To prepare a message, you create a section of code in the procedure where the error would occur. To start that section, you create a label. Here is an example: Private Sub cmdCalculate_Click() ThereWasBadCalculation: End Sub After (under) the label, you can specify your message. Most of the time, you formulate the message using a message box. Here is an example: Private Sub cmdCalculate_Click() ThereWasBadCalculation: MsgBox "There was a problem when performing the calculation" End Sub If you simply create a label and its message like this, its section would always execute: Private Sub cmdCalculate_Click() Dim HourlySalary As Double, WeeklyTime As Double Dim WeeklySalary As Double ' One of these two lines could produce an error, such as ' if the user types an invalid number HourlySalary = CDbl(txtHourlySalary) WeeklyTime = CDbl(txtWeeklyTime) ' If there was an error, the flow would jump to the label WeeklySalary = HourlySalary * WeeklyTime txtWeeklySalary = FormatNumber(WeeklySalary) ThereWasBadCalculation: MsgBox "There was a problem when performing the calculation" End Sub To avoid this, you should find a way to inte
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 VBA cannot correctly execute a program 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 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 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.

The term end statement should be taken to mean End Sub , End Function, End Property, or just End. The On Erro
