UnassignedVariableUsageInspection

(disabled)

Description: Use of unassigned variable

Type: CodeInspectionType.CodeQualityIssues

Default severity: CodeInspectionSeverity.Error

This inspection finds all usages of unassigned variables.

Example:

Field foo is referenced, but it's never assigned.

Dim foo As Integer
Public Sub DoSomething()
    Dim bar
    bar = foo
End Sub

When a variable is used, but never assigned, it's unlikely that the code is doing what it should be doing. Note that this inspection will not catch whether a variable is actually assigned before it is used.

QuickFixes

QuickFix: Remove usage (breaks code)

Dim foo As Integer
Public Sub DoSomething()
    Dim bar
    bar = TODO
End Sub

This quickfix replaces the unassigned reference with a TODO placeholder that is meant to break the code - if there's actually a declared variable in-scope that's called TODO, then this may be a problem. Otherwise, the idea is to put the code in a state that clearly needs to be addressed, as opposed to a state that merely compiles, but doesn't work as intended.
