Hi everyone.

I'm working on a script for a while know. Everything works fine except that the updating goes very slow.
I use the code below. I have a excel sheet with a range from A8:H282. When i use the update button it takes about 2 second before the new value has been listed and updated.

The other thing is that when the listbox has been loaded the scrollbox is very very long. So it displays the range but i can scroll a lot of white space after the listed range.

Code:
Private Sub UserForm_Initialize()
    Dim x As Long
    Dim k As Long
    Dim j As Long
    Dim rng As Range
   Set rng = Sheets("INPUT WV LISTBOX").Range("A8:H282") 
    Rx1 = 8 
    With ListBox1
    .RowSource = ""
    For k = 1 To rng.Rows.Count 'rows
        For j = 1 To rng.Columns.Count
        .AddItem
        .List(k - 1, j - 1) = rng.Cells(k, j).Text 'columns
        Next j, k
    End With
    For j = 1 To 8
        Me.Controls("TextBox" & j).Text = ""
    Next j
End Sub
Update button

Code:
Private Sub CommandButton2_Click()
    Dim j As Long
    Dim x As Long

    If Me.ListBox1.ListIndex = -1 Then
        MsgBox "No Data Selected"
        Exit Sub
    End If

    If Me.TextBox1.Value = "" Then Exit Sub

    Rx1 = Rx1 + Me.ListBox1.ListIndex    'row index
    With Sheets("INPUT WV LISTBOX")
        For j = 3 To 8  'columns Start in Column 4 but you wish to NOT change
            ' columns 4 through 7 so start in Column 8
            .Cells(Rx1, j).Value = Me.Controls("TextBox" & j - 0).Text   
        Next j
    End With
    Call UserForm_Initialize
End Sub
