If the next line raises an error, execution just skips that line, too.

If an error is raised, execution simply skips that line of code and goes to the next one. If you replace GoTo with Resume Next, you can defer error handling.

On Error GoTo fi圎rrors 'turns on fi圎rrors handler On Error Resume Next 'Defers error handling 'code that might error You can defer handling errors by using On Error Resume Next, like in this snippet: We’re going to talk about each of these roles in the next two sections. to return execution flow to the main body of the code after a custom handler completes.as a stand-in for a custom error handler that is marked by a label.This reduces the prevalence of runtime errors before they can even arise. It’s wise to check inputs for the correct data types, formatting, and common issues like a divisor of zero. Alternatively, exit the subroutine using Exit Sub, which automatically turns off the handler.Ĭalling another subroutine does not exit the current subroutine so any active handlers will be stacked in the new subroutine!Įrror handling code must be placed before the End Sub statement, so in order to avoid it running with the regular code, it should come after an Exit Sub statement. Doing so will close off the code block that uses that handler. To shut off (disable) the active handler, use On Error GoTo 0. The first line in the snippet turns on (enables) the fi圎rrors handler, and if an error occurs in that section, execution flow moves to the part of the code with the label fi圎rrors. On Error GoTo fi圎rrors 'some code that might trigger an error 'On Error GoTo 0 'uncomment to disable fi圎rrors and enclose the section Exit Sub fi圎rrors : 'code to fix the error 'Resume Next 'uncomment this to return to original code End Sub If you want to explicitly handle errors, label a section of code and direct the execution flow to that section: Of course, these things need a bit more explanation, otherwise we wouldn’t have written an entire tutorial about them!įor a more thorough exploration of basic error handling techniques, read our article dedicated to the On Error GoTo statement.Įrror handling in VBA is disabled by default, so it must be turned on with the On Error statement. In brief, Resume Next goes to the next executable line, GoTo 0 turns off the currently enabled error handler, and GoTo -1 turns off the current exception. These critical components add structure to the VBA On Error statement and any explicit handlers using GoTo. This tutorial focuses on the meaning and implementation of Resume Next, GoTo 0, and GoTo -1.
