Hi Experts

I need to be able to loop through the column headings in Row 1 of a spreadsheet (starting from column C  i.e "C1" and find the first column which contains value "Old_Address" and then delete this columns and all columns  after this.  So for example if "Old_Address" was found in Cell H1 then I would want all the columns from H onwards to be deleted.  The number of columns will change everyday.

Your assistance would be appreciated.

Thanks

Try this.
Dim varOldAdd As Variant
Dim LastCol As Long

    varOldAdd = Application.Match("Old_Address", Rows(1), 0)
    LastCol = Cells(1, Columns.Count).End(xlToLeft).Column

    If Not IsError(varOldAdd) Then
        Cells(1, varOldAdd).Resize(, LastCol - varOldAdd + 1).EntireColumn.Delete
    End If

Hi,  simsima_7876.

Please see attached. The code is...
Option Explicit

Sub Delete_Columns()
Dim xCol      As Range
Dim xLast_Col As Long
Dim i         As Long

Sheets("To Be Deleted").Activate

If ActiveSheet.UsedRange.Columns.Count > 0 Then xLast_Col = [A1].SpecialCells(xlLastCell).Column
If xLast_Col < 4 Then
    MsgBox ("No columns after C - run cancelled.")
    Exit Sub
End If

Set xCol = Range("1:1").Find(What:="Old_Address", LookIn:=xlValues, LookAt:=xlWhole, MatchCase:=False)
If xCol Is Nothing Then
    MsgBox ("""Old_Address"" not found.")
Else
    Range(Cells(1, xCol.Column), Cells(1, xLast_Col)).EntireColumn.Delete
    If ActiveSheet.UsedRange.Columns.Count < 0 Then Debug.Print "?!"
End If

End Sub

However in this case the value I am searching for is 41723 ( a numeric date) as opposed to the string Old_address

simsima,

The attached handles dates. The code is...
Option Explicit

Sub Delete_Columns()
Dim xCol      As Range
Dim xLast_Col As Long
Dim i         As Long
Dim xSearch   As Variant

Sheets("To Be Deleted").Activate

If ActiveSheet.UsedRange.Columns.Count > 0 Then xLast_Col = [A1].SpecialCells(xlLastCell).Column
If xLast_Col < 3 Then
    MsgBox ("No columns after B - run cancelled.")
    Exit Sub
End If

xSearch = DateSerial(2014, 3, 25)

Set xCol = Range(Cells(1, 3), Cells(1, xLast_Col)).Find(What:=xSearch, LookIn:=xlFormulas, LookAt:=xlWhole, MatchCase:=False)
If xCol Is Nothing Then
    MsgBox (xSearch & " not found.")
Else
    Range(Cells(1, xCol.Column), Cells(1, xLast_Col)).EntireColumn.Delete
    If ActiveSheet.UsedRange.Columns.Count < 0 Then Debug.Print "?!"
End If

End Sub
