VBA: Why would the Not operator stop working? [duplicate]

Answer 1

It's because of the internal Long value coming from this property, as explained by Cindy Meister. We should always use CInt to avoid this.

Sub testChangeBoolean2()
  Dim X As Boolean                     ' again, default is False
  X = CInt(Selection.Cells(1).FitText) ' [Fixed] does set X to True
  X = Not X                            ' X is False!
End Sub
