And thank you for the Resume

When writing new code, use the Err and Error objects, the AccessError function, and the Error event for getting information about an error. We appreciate your feedback. This is one example of code I use to check if the Microsoft ActiveX Data Objects 2.8 Library is added and if not add or use an earlier version if 2.8 Thanks to all!

The Immediate window is an object you can use to test functions and expressions. He is tech Geek who loves to sit in front of his square headed girlfriend (his PC) all day long. :D. Case 6 ' Divide by zero error MsgBox("You attempted to divide by zero!") ' Insert code to handle this error Case Else ' Insert code to handle other situations here... If a run-time error occurs, control branches to the specified line, making the error handler active.

You should do this only when you’re sure you’ve thought of everything that could possibly go awry—and the best way to arrive at that serene certainty is to test, test again, If this is your first visit, be sure to check out the FAQ by clicking the link above. That's a good idea to check for the references. 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.

For more information, see Try...Catch...Finally Statement (Visual Basic).Note The Error keyword is also used in the Error Statement, which is supported for backward compatibility.Syntax Copy On Error { GoTo [ line You can ask the compiler to let you deal with the error one way or another. Use this form rather than On Error GoTo when accessing objects.RemarksNote We recommend that you use structured exception handling in your code whenever possible, rather than using unstructured exception handling and If not, execution halts and an error message is displayed.

In reality, a program can face various categories of bad occurrences. On Error Resume Next statement doesn’t fix the runtime errors but it simply means that program execution will continue from the line following the line that caused the error. The On Error GoTo label statement enables an error-handling routine, beginning with the line on which the statement is found. The code works fine when the selected worksheet range includes numbers, text, or blank cells.

Any error will cause VBA to display its standard error message box. If you’re sure you’ve anticipated all the kinds of run-time errors that might occur with your program, On Error Resume Next can often be the simplest and most effective way to Notice that here I have used ‘Exit Sub' just before the ‘Error_handler:' label, this is done to ensure that the Error handler block of code doesn't execute if there is no error. First, some condition at the time the application is running makes otherwise valid code fail.

If you have not implemented error handling, Visual Basic halts execution and displays an error message when an error occurs in your code. Last edited by allankevin; Aug 7th, 2008 at 07:47 AM.

Reply With Quote Aug 7th, 2008,11:16 AM Some other errors depend on the platform that is running the application (the operating system, the processor, the version of the application, the (available) memory, etc).

To display the Immediate window, on the main menu of Microsoft Visual Basic, you can click View -> Immediate Window. To do this, you can use an If...Then conditional statement to check the number. 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. Note that Err.Clear is used to clear the Err object's properties after the error is handled.

For example, if you prompt the user for the name of a table to open, and the user enters the name of a table that does not exist, you can prompt d. This allows you to skip a section of code if an error occurs. But the next statement is a loop which is depended on the value of ‘N’, and at this step ‘N’ is uninitialized so this will have a side effect on the

Here is an example that tests the result of 275.85 + 88.26: One of the most basic actions you can perform in the Immediate window consists of testing a built-in function. Then clear the Err object.

It doesn't specify line 0 as the start of the error-handling code, even if the procedure contains a line numbered 0. Without an On Error GoTo -1 statement, an exception is automatically disabled when a procedure is exited.To prevent error-handling code from running when no error has occurred, place an Exit Sub, Where else than after presenting the error message to the user? 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
