Exclude Contents From List :


What would be your approach to do this job 🙂 

Suppose you have 2 List As showing below , and you need to remove List2 contents from List 1 , here is better code to accomplish this job , By using dictionary i just tried to make this process fast 🙂


Sub ExcludeFromList()


    Dim objDicMap As Object

    Dim VarArrData

    Dim VarArrResult

    Dim rngCell   As Range

    Dim lngCOunt As Long  

    VarArrData = Intersect(Range(“rngRange”).CurrentRegion, Range(“rngRange”).CurrentRegion.Offset(1))

    Set objDicMap = CreateObject(“Scripting.Dictionary”)    ‘ Dictionary Object get Mapping

    ‘Filling Dictionary

    For Each rngCell In Intersect(Range(“MapDelete”).CurrentRegion, Range(“MapDelete”).CurrentRegion.Offset(1))

        If Not objDicMap.exists(rngCell.Value) Then objDicMap.Add rngCell.Value, rngCell.Value

    Next rngCell

    ‘Filling Result Array From Data List which would not Include Mapping Data

    For lngCOunt = LBound(VarArrData) To UBound(VarArrData)

        If Not objDicMap.exists(VarArrData(lngCOunt, 1)) Then

            If Not IsArray(VarArrResult) Then

                ReDim VarArrResult(0 To 0)

                VarArrResult(0) = VarArrData(lngCOunt, 1)


                ReDim Preserve VarArrResult(UBound(VarArrResult) + 1)

                VarArrResult(UBound(VarArrResult)) = VarArrData(lngCOunt, 1)

            End If

        End If

    Next lngCOunt

    ‘Clear Old List


    ‘Replace with new list

    Range(“rngRange”).Offset(1).Resize(UBound(VarArrResult)).Value = Application.Transpose(VarArrResult)

    Set objDicMap = Nothing

    Set rngCell = Nothing

End Sub

Thanks for Reading 🙂

  1. JohnS says:

    Don’t you need a +1 in the final transpose?

    If isempty(VarArrResult) then
    debug.print “none missing”
    Range(“rngRange”).Offset(1).Resize(UBound(VarArrResult) +1 ).Value = Application.Transpose(VarArrResult)
    end if

  2. hmm.. you are right. thanks john for point out.
