Two Private Subs in One Worksheet [duplicate] - excel

Question

I am looking to limit my workbook users to 1000 characters over a range of cells (Example: A5:A30).
In other words limit the total characters in the range A5:A30 to 1000 characters.
When a user fills in a cell that sends the range over the 1000 character limit, it will call Application.undo which should just remove the last text that they added.
However since I have another Private Sub Worksheet_Change(ByVal Targe As Range) on the worksheet, it causes a bug.
Below is both Worksheet_Change subs. Both use the same cells.
Private Sub Worksheet_Change(ByVal Target As Range)
Dim charCount As Long
If Not Intersect(Target, Range("E6,E11,E16")) Is Nothing Then
Dim arrValues As Variant
arrValues = Range("E6,E11,E16").Value2
Dim i As Long
Dim tempSplit As Variant
Dim j As Long
For i = LBound(arrValues) To UBound(arrValues)
tempSplit = Split(arrValues(i, 1), " ")
For j = LBound(tempSplit) To UBound(tempSplit)
charCount = charCount + Len(tempSplit(j))
Next j
Next i
End If
If charCount > 1000 Then
Application.Undo
MsgBox "Adding this exceeds the 1000 character limit"
End If
If Not Intersect(Target, Range("D6")) Is Nothing Then
If Target.Value2 = "Material" Then
'assumes the comment cell is one column to the right
Target.Offset(0, 1) = "**"
End If
End If
If Not Intersect(Target, Range("D7")) Is Nothing Then
If Target.Value2 = "Material" Then
'assumes the comment cell is one column to the right
Target.Offset(-1, 1) = "**"
End If
End If
If Not Intersect(Target, Range("D8")) Is Nothing Then
If Target.Value2 = "Material" Then
Target.Offset(-2, 1) = "**"
End If
End If
End Sub
Is there a way around this so I can have two Worksheet_Change on the same worksheet?

Answer 1

You cannot have two Worksheeet_Change events in one sheet. But, one is quite enough:
Private Sub Worksheet_Change(ByVal Target As Range)
Select Case True
Case Not Intersect(ActiveCell, Range("A5:A30")) Is Nothing
DoThingOne
Case Not Intersect(ActiveCell, Range("B5:B30")) Is Nothing
DoThingTwo
End Select
End Sub
Private Sub DoThingOne()
Debug.Print "THING ONE"
End Sub
Private Sub DoThingTwo()
Debug.Print "THING TWO"
End Sub

How about this revision using Vityata's idea?
Private Sub Worksheet_Change(ByVal Target As Range)
Select Case True
Case Not Intersect(Target, Range("E6,E11,E16")) Is Nothing
Dim charCount As Long
Dim arrValues As Variant
arrValues = Range("E6,E11,E16").Value2
Dim i As Long
Dim tempSplit As Variant
Dim j As Long
For i = LBound(arrValues) To UBound(arrValues)
tempSplit = Split(arrValues(i, 1), " ")
For j = LBound(tempSplit) To UBound(tempSplit)
charCount = charCount + Len(tempSplit(j))
Next j
Next i
If charCount > 1000 Then
With Application
.EnableEvents = False
.Undo
.EnableEvents = True
End With
MsgBox "Adding this exceeds the 1000 character limit"
End If
Case Not Intersect(Target, Range("D6")) Is Nothing
If Target.Value2 = "Material" Then
'assumes the comment cell is one column to the right
Target.Offset(0, 1) = "**"
End If
Case Not Intersect(Target, Range("D7")) Is Nothing
If Target.Value2 = "Material" Then
'assumes the comment cell is one column to the right
Target.Offset(-1, 1) = "**"
End If
Case Not Intersect(Target, Range("D8")) Is Nothing
If Target.Value2 = "Material" Then
Target.Offset(-2, 1) = "**"
End If
End Select
End Sub
