excel 2010 vba exit on error Chester Gap, Virginia

The Raise method generates a specific error and populates the properties of the Err object with information about that error. If an error occurs, then execution passes to the exit routine after the code in the error-handling routine has run. For Error Handling to work properly in VBA, you need a Resume statement to clear the Error Handler. To determine the descriptive string associated with an Access error, an ADO error, or a DAO error that has not actually occurred, use the AccessError method.

For instance: For example I have a simple macro as follows: Sub GetErr() On Error Resume Next N = 1 / 0    ' Line causing divide by zero exception For i Do Until x > InsertRange.Row 'Line 8 'If structure to determine if the value in the cell 'being evaluated is a number, and is not zero. 'Note, "IsNumeric" is used instead Why are so many metros underground? Whenever an error occurs, code execution immediately goes to the line following the line label.

Add the following code line to the loop. Please share this page on Google+ 3/6 Completed! Because errors can occur in different parts of your application, you need to determine which element to use in your code based on what errors you expect. The values of the ADO Number or DAO Number properties and the ADO Description or DAO Description properties of the first Error object in the Errors collection should match the values

If you don't already have a constants module, create one that will contain an ENUM of your custom errors. (NOTE: Office '97 does NOT support ENUMS.). Call the raiseCustomError Sub in the routine you may see the custom error ' 4. To set Err.Number for your custom error, add the number you select as an error code to the vbObjectError constant (-2147221504) to ensure your custom error number is not in conflict And thank you for the Resume

x = 1 'Line 7 'Define the loop to instruct Excel to stop looking at cells 'past the row where the original range's last value will be. The Error Event You can use the Error event to trap errors that occur on an Access form or report. Going to be away for 4 months, should we turn off the refrigerator or leave it on with water inside? The following code attempts to activate a worksheet that does not exist.

Second, your code may contain improper logic that prevents it from doing what you intended. I have a list of cells with numbers and what the macro does is insert "x" number of rows based on whatever the number is in the row (above) the active First, some condition at the time the application is running makes otherwise valid code fail. If an error-handling routine is enabled, execution passes to the error-handling routine when an error occurs.

We will concern ourselves here only with run time errors. You must immediately set another On Error statement to avoid problems as the previous error handler will "resume". MarksPercent = Marks / TotalMarks * 100 MarksPercent = Round(MarksPercent, 2) End Function       If an error occurs in a called procedure within an active error handler which does The second form, On Error Resume Next , is the most commonly used and misused form.

It does not specify line 0 as the start of the error-handling code, even if the procedure contains a line numbered 0. The following code causes an error (11 - Division By Zero) when attempting to set the value of N. Exit_MayCauseAnError: Exit Function Error_MayCauseAnError: . ' Include code to handle error. . . ' Resume execution with exit routine to exit function. Dim intErrNum As Integer intErrNum = Err Err.Clear Err.Raise intErrNum End If ' Resume execution with exit routine to exit function.

Const conTypeMismatch As Integer = 13 On Error GoTo Error_MayCauseAnError . ' Include code here that may generate error. . .

Description property) to zero-length strings ("").

That could cause the error to repeat and enter an infinite loop. For example, the following procedure specifies that if an error occurs, execution passes to the line labeled : Copy Function MayCauseAnError() ' Enable error handler. The Err Object The Err object is provided by Visual Basic. Error_MayCauseAnError: . ' Include code here to handle error. . .

An 'enabled' error handler is the one which is enabled by the On Error Statement; an 'active' error handler is the 'enabled' error handler which is in the process of handling Yes No Additional feedback? 1500 characters remaining Submit Skip this Thank you!
