ImplicitContainingWorkbookReference

Locates unqualified Workbook.Worksheets/Sheets/Names member calls inside workbook document modules that implicitly refer to the containing workbook.

New This feature is currently only available in pre-release builds (or the xmldoc asset doesn’t yet exist on main!).

Inspection type: CodeQualityIssues

Default severity: Warning

Reasoning

Implicit references inside a workbook document module can be mistakes for implicit references to the active workbook, which is the behavior in all other modules By explicitly qualifying these member calls with Me, the ambiguity can be resolved.

This inspection will only run if the Excel library is referenced.

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.
  • 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.
  • QualifyWithMe: Qualifies an implicit reference with 'Me'.

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 trigger this inspection:

ThisWorkbook

Private Sub Example()
    Dim summarySheet As Worksheet
    Set summarySheet = Worksheets("Summary") ' unqualified Worksheets is implicitly querying the containing workbook's Worksheets collection.
End Sub
