LB_GETTEXT, does it work?

[Oafo]

I've tried many times trying to get ALL the text from a ListBox. But nothing seems to work, I've tried searching through posts and stuff, but nobody seems to want what I need. How can I get all of the text from a ListBox, and put it in a TextBox? Example:

The ListBox looks like this:

Dog
Cat
Cow
Horse

and when you press a button, the TextBox looks like this:

Dog
Cat
Cow
Horse

Anyone know how to do this??

In a Module:

Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hWnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long

Private Const LB_GETCOUNT = &H18B
Private Const LB_GETTEXT = &H189
Private Const LB_GETTEXTLEN = &H18A

Public Function GetListBoxItems(ByVal hWnd As Long) As String
    Dim lCount As Long, lIndex As Long
    Dim sItem As String, lLen As Long
    Dim sList As String
    
    ' Find the no. of items in the listbox
    lCount = SendMessage(hWnd, LB_GETCOUNT, 0&, ByVal 0&)
    ' Enumerate the items
    For lIndex = 0 To lCount - 1
        ' Get the length of the Item Text
        lLen = SendMessage(hWnd, LB_GETTEXTLEN, lIndex, ByVal 0&)
        ' Create a buffer of the specified length
        sItem = Space(lLen)
        ' Extract the Item Text into the buffer
        Call SendMessage(hWnd, LB_GETTEXT, lIndex, ByVal sItem)
        ' Add it to the string
        sList = sList & vbCrLf & sItem
    Next
    ' Return the string minus the first preceeding CRLF
    GetListBoxItems = Mid(sList, 3)
End Function 

Example Usage:

Private Sub Form_Load()
    Dim lIndex As Long
    For lIndex = 1 To 10
        List1.AddItem "Item " & lIndex
    Next
End Sub

Private Sub Command1_Click()
    ' Using Local Listbox for example, but could pass the Handle of any external Listbox
    Text1 = GetListBoxItems(List1.hWnd)
End Sub

Private Sub Command1_Click()

Dim i as integer
Dim s as String

for i = 0 to List1.Listcount-1
s=s & List1.List(i) & vbNewLine
next

Text1.Text = s

end sub
