'This function returns the string equivalent of a column index
Public Function GetCol(ByVal idx As Integer) As String
Dim j As Integer, s As String
If idx > 0 And idx <= 256 Then 'Check limits
idx = idx - 1 'Shift it to 0's scale
j = idx Mod 26
s = Chr$(65 + j)
idx = Int(idx - j) / 26
If idx > 0 Then s = Chr$(64 + idx) & s
GetCol = s
End If
End Function
'This function returns the integer equivalent of a column index in string
Public Function GetIdx(ByVal col As String) As Integer
Dim j As Integer, i As Integer, c As String
col = UCase$(Trim$(col))
j = Len(col)
If j > 0 And j <= 2 Then 'Check limits
c = Right$(col, 1)
i = Asc(c) - 64
If j = 2 Then
c = Left$(col, 1)
i = i + (Asc(c) - 64) * 26
End If
GetIdx = i
End If
End Function
