Identifies the use of indexed default member accesses that require a recursive default member resolution.

Inspection type: CodeQualityIssues

Default severity: Warning


Default member accesses hide away the actually called member. This is especially misleading if there is no indication in the expression that such a call is made and the final default member is not on the interface of the object itself. In particular, this can cause errors in which a member was forgotten to be called to go unnoticed


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.
  • ExpandDefaultMember: Makes default member calls explicit.
  • 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.


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 Function Foo() As Class2
    Attibute Foo.VB_UserMemId = 0
    Set Foo = New Class2
End Function


Public Function Bar() As Long
    Attibute Bar.VB_UserMemId = 0
    Foo = 42
End Function


Public Sub DoSomething(ByVal arg As Class1)
    Dim bar As Variant
    bar = arg
End Sub
