Adjust Listbox.Height problems - excel

Question

I have a userform with a textbox and a listbox with the following plan:
Users input text in Textbox1.
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.

Answer 2

#T.M.: Thank you for your quick response and for your time. Your answer gave me exactly what I wanted and that's why I'm marking it as such. I'm posting this just for future reference.
What I finaly did to implement the plan.
First of all I inserted:
this
With ListBox1
.Top = 18
.Font.Size = 10
.IntegralHeight = False
and this
.Height = .Height + .Font.Size + 2
.IntegralHeight = True
End With
and I linked .Height with .Font.Size as you suggested. As long as there was no need to assign absolute values to the height, there was no need to have a Select Case statement in my code.
Moreover I realized that there was no need to change the height every time an item was added but only at the end of the process, so I took it out of the loop.
Finally I added a piece of code that would make the list invisible when Textbox1 was empty. The code is now like this:
Final Userform code:
Option Compare Text
Option Explicit
Private bsdel As Boolean 'indicates if backspace or delete keys have been hit.
Private Sub ListBox1_Click()
Dim cell As Range
Dim maxRow As Integer
With ThisWorkbook.Worksheets(1)
maxRow = .Cells(.Rows.Count, 2).End(xlUp).Row
Set cell = .Range("A1:A" & maxRow).Find(UserForm11.ListBox1.Text, LookIn:=xlValues, lookat:=xlWhole)
If Not cell Is Nothing Then
cell.Select
'do other stuff also.
End If
End With
End Sub
Private Sub TextBox1_KeyDown(ByVal KeyCode As MSForms.ReturnInteger, ByVal Shift As Integer)
bsdel = False
If KeyCode = 8 Or KeyCode = 46 Then _
bsdel = True
End Sub
Private Sub TextBox1_Change()
Dim srchWord As String, firstAddress As String
Dim srchRng As Range, cell As Range
Dim maxRow As Integer
ListBox1.Clear
ListBox1.Visible = True
If bsdel And TextBox1.Value = "" Then
ListBox1.Visible = False
Me.Height = 130
Else
With ThisWorkbook.Worksheets(1)
maxRow = .Cells(.Rows.Count, 2).End(xlUp).Row
Set srchRng = .Range("A1:A" & maxRow)
End With
srchWord = TextBox1.Value
Set cell = srchRng.Find(srchWord, LookIn:=xlValues, lookat:=xlPart)
With ListBox1
'.Top = 84 'test made: deleting this made no difference.
'.Font.Size = 10 'test made: deleting this made no difference.
.IntegralHeight = False
If Not cell Is Nothing Then
firstAddress = cell.Address
Do
If Not cell.Value Like "*(*" Then 'this range includes notes within parenthesis and I didn't need them.
.AddItem (cell.Value)
End If
Set cell = srchRng.FindNext(cell)
Loop While Not cell.Address = firstAddress
If .ListCount < 21 Then 'the size is adjusted.
.Height = (.Font.Size + 2) * .ListCount
Else 'the size stays fixed at maximum.
.Height = (.Font.Size + 2) * 20
End If
End If
Me.Height = .Height + 130
.Height = .Height + .Font.Size + 2
.IntegralHeight = True
End With
End If
bsdel = False
End Sub
Private Sub UserForm_Activate()
TextBox1.SetFocus
End Sub
Private Sub UserForm_Initialize()
ListBox1.Visible = False
End Sub
