Adjust Listbox.Height problems

Question

I have a userform with a textbox and a listbox with the following plan:

1. Users input text in Textbox1.
2. Every time Textbox1.Text changes, a search with the following features is performed:
   • Textbox1.Text is searched in a specific range in a worksheet.
   • Textbox1.Text can be found more than once.
   • Listbox1 is populated with the results of the search.

So far so good. Due to having large set of data, the list can get many items. In this case the list reaches out of the screen and I had to limit Listbox1.Height. This is the code for the above:

Private Sub TextBox1_Change()
    Dim srchWord As String, firstAddress As String
    Dim srchRng As Range, cell As Range
    Dim maxRow As Integer

    ListBox1.Clear
    If TextBox1.Value = "" Then
        ListBox1.Height = 0
    Else
        With ThisWorkbook.Worksheets(1)
            maxRow = .Cells(.Rows.Count, 2).End(xlUp).Row
            Set srchRng = .Range("A2:A" & maxRow)
        End With
        srchWord = TextBox1.Value
        Set cell = srchRng.Find(srchWord, LookIn:=xlValues, lookat:=xlPart)

        With ListBox1
        If Not cell Is Nothing Then
            firstAddress = cell.Address
            Do
                If Not cell.Value Like "*(*" Then
                    .AddItem (cell.Value)
                    Select Case .ListCount
                        Case Is < 2
                            .Height = 17
                        Case Is < 21
                            .Height = 15 * .ListCount
                        Case Else
                            .Height = 272.5
                    End Select
                    Me.Height = 500
                End If
                Set cell = srchRng.FindNext(cell)
            Loop While Not cell.Address = firstAddress
        End If
        End With
    End If
End Sub

The problem was in Case Else when scroll was enabled I couldn't reach the last item of the list. By searching on the net I found some potential solutions:

• set Listbox1.IntegralHeight = False set the height and then set again Listbox1.IntegralHeight = True
• set Listbox1.MultiSelect = fmMultiSelectSingle and then set again Listbox1.MultiSelect = fmMultiSelectExtended.
• do both of the above.
• Application.Wait (Now + TimeValue("0:00:01") * 0.5) and then set the height.

None of these worked. To be able to scroll to the last item, this worked:

Listbox1.IntegralHeight = False
Listbox1.Height= x
Listbox1.IntegralHeight = False
Listbox1.Height= x

but this also set the Listbox1.Height to this of one single item. (with arrows at the right)

Does anybody know how on earth am I going to control the Listbox1.Height without all this unwanted behaviour? Also if somebody can suggest another structure that could follow the plan mentioned at first, I 'm willing to discard the listbox.

Answer 1

This seems to be a not completely explored behaviour.

• In my experience just redefine some listbox arguments.

• Try the recommended sets of .IntegralHeight to False and True.

• Another possible measure can help in some cases: try to choose heights for your listbox that come close to the following multiplication:

listbox height = (font size + 2 pts) * (maximum items per page)

Insert the following code after With ListBox1:

  With ListBox1
    .Top = 18                   ' << redefine your starting Point
    .Font.Size = 10             ' << redefine your font size
    .IntegralHeight = False     ' << try the cited recommendation :-)

Insert the following code before End With:

    .Height = .Height + .Font.Size + 2
    .IntegralHeight = True
    End With

Hope that helps.
