Find and replace VBA code using VBA

It is sometimes necessary to update your code, a quick find and replace (Ctrl+H) will often be enough.  I’d also recommend the MZ Tools VBE toolbar, it has a lot to add to your VBA coding experience, including a very good search tool.

Sometimes the above is not quite want you want.  So below is a simple bit of code you can use to replace one line of code for another.

Public Sub FindAndReplace()
'-----------------------------------------------------------------------------' Procedure : FindAndReplace
' Purpose   : Searches the active workbook for a specific code line and
'             replaces it with a new code line
'-----------------------------------------------------------------------------
    Dim SL As Long, EL As Long, SC As Long, EC As Long
    Dim S As String
    Dim Found As Boolean
    Dim sFind As String
    Dim sReplace As String

    sFind = "my old line of code"
    sReplace = "my new line of code"

    With ActiveWorkbook.VBProject.VBComponents("MyCodeModule").CodeModule
        SL = 1
        SC = 1
        EL = 99999
        EC = 999
        Found = .Find(sFind, SL, SC, EL, EC, True, False, False)
        If Found = True Then
            S = .Lines(SL, 1)
            S = Replace(S, sFind, sReplace)
            .ReplaceLine SL, S
        End If
    End With

End Sub

SL / SC is the start line / start column and EL / EC is the end line / end column.  These can be changed to target code lines within a specific part of your code.

I hope the above proves useful.  As always, any questions let us know via the comments.
