Finds instances of 'On Error Resume Next' that don't have a corresponding 'On Error GoTo 0' to restore error handling.

Inspection type: CodeQualityIssues

Default severity: Warning


'On Error Resume Next' should be constrained to a limited number of instructions, otherwise it supresses error handling for the rest of the procedure; 'On Error GoTo 0' reinstates error handling. This inspection helps treating 'Resume Next' and 'GoTo 0' as a code block (similar to 'With...End With'), essentially


The following quick-fixes are available for this inspection:

  • IgnoreOnce: Adds an '@Ignore annotation to ignore a specific inspection result. Applicable to all inspections whose results can be annotated in a module.
  • IgnoreInModule: Adds an '@IgnoreModule annotation to ignore a inspection results for a specific inspection inside a whole module. Applicable to all inspections whose results can be annotated in a module.
  • RestoreErrorHandling: Introduces an error-handling subroutine to ensure error state is properly handled on scope exit.


Each example is a self-contained MCVE showing the feature in a single specific scenario.

Standard Module
Named Module1 by default, these are general-purpose standard procedural modules.
Class Module
Named Class1 by default, these modules define the default interface for an object of that type.
Predeclared Class
A class module with its VB_PredeclaredId attribute set to True (with or without a @PredeclaredId annotation).
Interface Module
Abstract interfaces are class modules (with or without an @Interface annotation) whose default interface is not a class type intended to be instantiated.
UserForm Module
A predeclared class with a design-time visual designer using the MSForms UI framework.
Document Module
Owned by the host application, these class modules belong to the host document and may handle various events fired by the host application.

The following code should trigger this inspection:


Public Sub DoSomething()
    On Error Resume Next ' error handling is never restored in this scope.
    ' ...
End Sub
