  • This isn't standard practice in VBA. If you are trying to make your code portable, I'd suggest either Gary's answer on assigning to a button or my answer on using onchange event.
  • Thanks Gary. Great help!
  • That isn't proper VBA syntax.
  • Fairly certain this isn't valid code in any language. Looks like you've mixed together VBA and C#. And even if the syntax was correct, this does not do what the question asks.
  • If (Range("A1").Value = Range("B1").Value) Then MsgBox ("Equals") Else MsgBox ("Not Equals") End If
  • Syntax works, but still doesn't answer the original Q.
  • If (Range("A1").Value = Range("B1").Value) Then Range("C1").Value = "Yes" Else Range("C1").Value = "No" End If
