I've got a job that involves loading a spreadsheet with data from SQL Server. I don't have a problem with retrieving the data via ADO and a stored procedure, but I have found it very messy when working with ranges in VBA when you have to set a range based on an area of non-blank cells that can expand/contract and could be empty.

So came up with these routines that I hope to use elsewhere, not fully tested I hasten to add...

I chose to work only with row/column index values, if you use A1 notation you have to keep building strings that seems more messy. Don't know if this the best approach.

For module:

Code:

```
'***Change for version of Excel***
Private Const ExcelMaxRow = 1048576
Private Const ExcelMaxCol = 16384
Public Function GetRngArea(ThisSheet As Worksheet, StartRow As Long, StartCol As Long, _
Optional EndRow As Long = -1, Optional EndCol As Long = -1, _
Optional SearchColForEndRow As Long = -1, Optional SearchRowForEndCol As Long = -1) As Range

End If
'check for defined area

End If
'return - OK if here

End If

End Function
Public Function GetLastRow(ThisSheet As Worksheet, SearchCol As Long) As Long
'Find last row based on search column, going up from cell in column at bottom edge of sheet to first non-blank cell
Dim MaxRow As Long
MaxRow = ExcelMaxRow
GetLastRow = ThisSheet.Range(Cells(MaxRow, SearchCol), Cells(MaxRow, SearchCol)).End(xlUp).Row
End Function
Public Function GetLastCol(ThisSheet As Worksheet, SearchRow As Long) As Long

Dim MaxCol As Long
MaxCol = ExcelMaxCol
GetLastCol = ThisSheet.Range(Cells(SearchRow, MaxCol), Cells(SearchRow, MaxCol)).End(xlToLeft).Column
End Function
```

And for testing:

Code:

```
Private Sub CommandButton1_Click()
Dim ThisWorkbook As Workbook
Dim ThisSheet As Worksheet
Dim ThisRange As Range
Set ThisWorkbook = Application.ActiveWorkbook
Set ThisSheet = ThisWorkbook.ActiveSheet
ThisSheet.Range("A1") = ""
Set ThisRange = GetRngArea(ThisSheet, 2, 3, 7, 8)
If ThisRange Is Nothing Then
ThisSheet.Range("A1") = "Nothing"
Else
ThisRange.Select
End If
End Sub
```

Thanks in advance for any suggestions.
