Test for a range that evaluates to nothing

Hi

I am using excel in office 2013.   The following code fails when there are no constants in the selected range.  It works fine if the range does not evaluate to nothing.

I need the following logic

If rStoreConstants  <> nothing then do something


Dim RStoreConstants As Range
Set RStoreConstants = TheWorkSheet.Range(Cells(FirstRow, 1), Cells(Lastrow, LastColumn)).SpecialCells(xlCellTypeConstants)

Hi,

You will need to ignore errors (with an On Error Resume Next statement above your existing code), but you may use this:

If Not (RStoreConstants Is Nothing) Then
rem Do Something here
End If

I've used this code.  A pop up comes up saying "No cells were found."

If Not TheWorkSheet.Range(Cells(FirstRow, 1), Cells(Lastrow, LastColumn)).SpecialCells(xlCellTypeConstants) Is Nothing Then
        Set RStoreConstants = TheWorkSheet.Range(Cells(FirstRow, 1), Cells(Lastrow, LastColumn)).SpecialCells(xlCellTypeConstants)
End If

Are the cell values in the range the result of formulas?

mixed.   There are always formulas in the selected range.   There may be constants.

This code performs as you expected (because of the On Error Resume Next statement, as I mentioned above):

  Dim LastColumn                                        As Integer
  Dim FirstRow                                          As Long
  Dim LastRow                                           As Long
  Dim RStoreConstants                                   As Range
  Dim TheWorkSheet                                      As Worksheet
  
  LastColumn = 20
  FirstRow = 1&
  LastRow = 10&
  
  Set TheWorkSheet = ActiveSheet
  Set RStoreConstants = Nothing
  
  On Error Resume Next
  Set RStoreConstants = TheWorkSheet.Range(Cells(FirstRow, 1), Cells(LastRow, LastColumn)).SpecialCells(xlCellTypeConstants)
  On Error GoTo 0
  
  If Not (RStoreConstants Is Nothing) Then
     Rem Do Something
  End If
