VBA - Using InStr to find substring and cut characters into offset cell

[spidaman]

Can anyone help with an error I am getting when using the InStr function please?

I want the code to identify the column with header 'To' which can occur in variable position, then search the 'To' column for a specific substring. For each cell containing the substring I need the Offset.(0, -1) cell value to equal the substring plus all characters to the right of the substring (this will never be more than 20 characters).

To make it clear titRng is my title range, ToRng is my 'To' column range and MyString1 is the substring I want to find.

I have tried this using .Find function but also struggled with that option so am trying to make it work with InStr method.

Sub Action_MyCel_v1()


Dim Mycel As Range, foundCell1 As Range, titRng As Range, ToRng As Range
Dim wb1 As Workbook
Dim ws1 As Worksheet, origTAB1 As Worksheet
Dim MyPos1 As Integer
Dim TargetStr1 As String, MyString1 As String


Set wb1 = ActiveWorkbook
Set ws1 = wb1.Sheets("Messages")


    ws1.Copy After:=Sheets(Sheets.Count)
    Set origTAB1 = ActiveSheet
    origTAB1.Name = "Original Messages"
    
    ws1.Activate
    
    TargetStr1 = "To"
    Set titRng = ws1.Rows(1)


    Set foundCell1 = titRng.Find(What:=TargetStr1, LookIn:=xlValues, _
    LookAt:=xlWhole, SearchOrder:=xlByRows, SearchDirection:=xlPrevious, _
    MatchCase:=True, SearchFormat:=False)
    
    Set ToRng = foundCell1.EntireColumn
    
    MyString1 = "Name:"
    
    For Each Mycel In ToRng
    
        ' Error thrown on next row
        If InStr(1, Mycel.Value, MyString1) > 0 Then


            MyPos1 = InStr(Mycel, MyString1, 1)
            Mycel.Offset(0, 1).Value = Mid(MyString1, MyPos1, 20)
        
        End If
        
    Next Mycel


End Sub

I assume I can't use MyString1 within the InStr function but if not then how else can I make it work? Also I'd like to actually cut the characters out of the cell rather than just copy them.

Any suggestions welcome and thanks in advance for taking a look.

Try changing your 'LookAt:=xlWhole' to 'LookAt:=xlPart'. But if any of your other header before the target header has 'To'' in it, it will give you that cell for a return value.

If you could post and example of the headers you are searching, it would help determine the best approach.

Hi JLGWhiz thanks for your reply.

Typical column headers here:

[TABLE="width: 674"]
<tbody>[TR]
[TD="class: xl63, width: 75, align: left"]Application[/TD]
[TD="class: xl63, width: 64, align: left"]Direct[/TD]
[TD="class: xl63, width: 64, align: left"]Time[/TD]
[TD="class: xl63, width: 64, align: left"]Thread ID[/TD]
[TD="class: xl63, width: 64, align: left"]To[/TD]
[TD="class: xl63, width: 64, align: left"]Created[/TD]
[TD="class: xl63, width: 64, align: left"]Type[/TD]
[TD="class: xl63, width: 151, align: left"]Related ID[/TD]
[TD="class: xl63, width: 64, align: left"]From
[/TD]
[/TR]
</tbody>[/TABLE]


I hadn't thought of an error in finding 'foundCell1' in 'TitRng' tbh.

Have tried changing to xlPart but still raising an error.

Thanks

Try just this for the find statement.

Set foundCell1 = titRng.Find(TargetStr1, xlValues, xlWhole)

One problem was you were searching by rows, so it probably only checked the first cell.

I think the problem is you set ToRng as an entire column

Set ToRng = foundCell1.EntireColumn

You should limit the range within the last row with data, something like this:

Dim x As Long
    x = foundCell1.Column
    Set ToRng = Range(Cells(2, x), Cells(Rows.count, x).End(xlUp))

I think it was too late last night when I was looking at this. I re-read the OP and think maybe this version will work.

Sub Action_MyCel_v2()
Dim Mycel As Range, foundCell1 As Range, titRng As Range, ToRng As Range
Dim wb1 As Workbook
Dim ws1 As Worksheet, origTAB1 As Worksheet
Dim MyPos1 As Integer
Dim TargetStr1 As String, MyString1 As String
Set wb1 = ActiveWorkbook
Set ws1 = wb1.Sheets("Messages")
    ws1.Copy After:=Sheets(Sheets.Count)
    Set origTAB1 = ActiveSheet
    origTAB1.Name = "Original Messages"
    ws1.Activate
    TargetStr1 = "To"
    Set titRng = ws1.Rows(1)
    Set foundCell1 = titRng.Find(What:=TargetStr1, LookIn:=xlValues, _
    LookAt:=xlWhole, SearchOrder:=xlByRows, SearchDirection:=xlPrevious, _
    MatchCase:=True, SearchFormat:=False)
    Set ToRng = Intersect(foundCell1.EntireColumn, ws1.UsedRange)
    MyString1 = "Name:"
    For Each Mycel In ToRng
        ' Error thrown on next row
        If InStr(Mycel.Value, MyString1) > 0 Then
            MyPos1 = InStr(Mycel, MyString1)
            Mycel.Offset(0, 1).Value = Mid(Mycel.Value, MyPos1, 20)
        End If
    Next Mycel
End Sub

        End If
    Next Mycel
End Sub

Except for creating the "Original Messages" worksheet (not sure I see a reason to do that) and if I am not mistaken, I believe the following code should do the same thing as your above code does...

[table="width: 500"]
[tr]
	[td]Sub Action_MyCel_v3()
  Dim Col As Long, MyString1 As String
  MyString1 = "Name:"
  Col = Rows(1).Find("To", , xlValues, xlWhole, , , True, , False).Column
  With Range(Cells(2, Col), Cells(Rows.Count, Col).End(xlUp)).Offset(, 1)
    .Offset(, -1).Copy .Cells
    .Value = Evaluate(Replace(Replace("IF(@="""","""",REPLACE(@,1,SEARCH(""#"",@&""#"")-1,""""))", "@", .Address), "#", MyString1))
  End With
End Sub[/td]
[/tr]
[/table]

 

[JLGWhiz]

In case the OP can't unscramble the condensed code.

Sub Action_MyCel_v3()
Dim Col As Long, MyString1 As String
MyString1 = "Name:"
Col = Rows(1).Find("To", , xlValues, xlWhole, , , True, , False).Column
    With Range(Cells(2, Col), Cells(Rows.Count, Col).End(xlUp)).Offset(, 1)
        .Offset(, -1).Copy [COLOR=#ff0000]'Not sure what this is for[/COLOR]
        .Cells .Value = Evaluate(Replace(Replace("IF(@="""","""",REPLACE(@,1,SEARCH(""#"",@&""#"")-1,""""))", "@", .Address), "#", MyString1))
    End With
End Sub

 

[rlv01]

        .Offset(, -1).Copy [COLOR=#ff0000]'Not sure what this is for[/COLOR]
End Sub

Without it, the Evaluate function cannot access the values in the range and you get an empty results array. Not sure why.

[TABLE="width: 500"]

[TD]Sub Action_MyCel_v3()
  Dim Col As Long, MyString1 As String
  MyString1 = "Name:"
  Col = Rows(1).Find("To", , xlValues, xlWhole, , , True, , False).Column
  With Range(Cells(2, Col), Cells(Rows.Count, Col).End(xlUp)).Offset(, 1)
    .Offset(, -1).Copy .Cells
    .Value = Evaluate(Replace(Replace("IF(@="""","""",REPLACE(@,1,SEARCH(""#"",@&""#"")-1,""""))", "@", .Address), "#", MyString1))
  End With
End Sub[/TD]
[/TR]
</tbody>[/TABLE]

@Rick Rothstein - thanks very much! This code does what I was trying to do (just needed to change the column Offset.

The creation of the "Original Messages" worksheet is just to retain copy of the original worksheet (a back-up without creating another file).

I am not familiar with the way you have used the Evaluate function here:

[COLOR=#333333][FONT=monospace]Evaluate(Replace(Replace("IF(@="""","""",REPLACE(@,1,SEARCH(""#"",@&""#"")-1,""""))", "@", .Address), "#", MyString1))[/FONT][/COLOR]

Would you be willing to help me understand how this function is returning the characters to the right of MyString1 from the original cell please?
