Personal Macro Workbook – you will be able to see this macro in all workbooks you openĢ. Next choose where to store the macro in one of the 3:ġ. Pressing all of the shortcut keys at once will automatically cause the macro to run, assuming that workbook is open. Note that it will default to Ctrl + (your input), but if you use a capitol letter then it will look as above. The shortcut key can be specified as a keyboard shortcut not already used. Macros have restrictions on their names, but mostly be sure to use an underscore (_) between words. The macro name will default to Macro1 (or whatever number of macro you are making). This method is more suitable for exiting the program gracefully if any fatal error occurs during the execution.īelow is a self-explanatory example of ‘On Error Goto:’ where I have used the label name as ‘Error_handler’.This box will pop up on the screen. In such cases, all the statements between the exception line and the label will not be executed. This statement tells the VBA to transfer the program control to the line followed by the label, in case any runtime errors are encountered. This is the third form in which VBA On Error statement can be used.

And hence we have set ‘N’ to its minimum value so that there are no side effects in the code due to uninitialized variables. Number property, if it is not equal to zero that means there is some exception in the code.

Now, here in this code, we are checking the Err. N = 2 ' Some minimum value of N if there is some exception in the code. N = 1 / 0 ' Line causing divide by zero exception When an exception occurs, the Err object is updated to include information about that exception.įor example, I have a simple macro as follows: The Err object preserves information about one exception at a time. Err object in VBA comes into the picture whenever any runtime error occurs. This can be ensured by using the VBA Err object. However, it is the sole responsibility of the programmer to make sure that any handled error should not have any side effects (like uninitialized variables or null objects) on the program execution. 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. This statement tells the VBA program to ignore the error and resume the execution with the next line of code. It is the second form of the On Error statement. Help: This button will open Microsoft MSDN help pages for that exception. Debug: This option will bring the program control back to the statement from where the exception has occurred. Continue: This will ignore the exception and continue the code, only if it is possible to do so.Ĭ. This message box will give you four options:Ī. Here we are instructing the program to display the standard runtime message box with ‘Continue’, ‘End’, ‘Debug’, and ‘Help’ buttons. When On Error Goto 0 is in effect, it is the same as having no error handler in the code. This is also called VBA default exception handling. Syntax of On Error Statement:īasically, there are three types of On Error statement: On Error statement instructs VBA Compiler, what to do in case any runtime exception is thrown.
