[RESOLVED] search listbox

can anybody show me how to do a binary search in a sorted listbox ?

thanks.

Not sure if this is Binary, but it is the quickest way to search it.

VB Code:

Option Explicit
 
Private Declare Function SendMessageString Lib "user32" Alias "SendMessageA" _
(ByVal hWnd As Long, _
ByVal wMsg As Long, _
ByVal wParam As Long, _
ByVal lParam As String) As Long
Private Const CB_FINDSTRINGEXACT = &H158
Private Const LB_FINDSTRINGEXACT = &H1A2
Public newitem As String
 
 
Sub searchlist()
  Dim lngRetVal As Long
  lngRetVal = SendMessageString(List1.hWnd, _
              LB_FINDSTRINGEXACT, -1&, _
              newitem)
  If lngRetVal = -1& Then
    List1.AddItem newitem
  Else
    List1.ItemData(lngRetVal) = List1.ItemData(lngRetVal) + 1
    MsgBox List1.ItemData(lngRetVal)
    ' It's already in the list and lngRetVal is the listindex
  End If

thanks but its not what i am after.

i am doing a listbox usercontrol and i want to do a sorted sub so when i add a new item i need to know which index to put it so i know the binary search will be the quickest but i dont know how to do it.

thanks.

ok, i got it.

thanks.
