ModuleScopeDimKeyword

Warns about module-level declarations made using the 'Dim' keyword.


Inspection type: LanguageOpportunities

Default severity: Suggestion

Reasoning

Private module variables should be declared using the 'Private' keyword. While 'Dim' is also legal, it should preferably be restricted to declarations of procedure-scoped local variables, for consistency, since public module variables are declared with the 'Public' keyword

Quick-Fixes

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.
  • ChangeDimToPrivate: Replaces the Dim keyword with Private in a module-scoped declaration.
  • 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.

Examples

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 NOT trigger this inspection:

MyModule

Option Explicit
Private foo As Long
