Search as you type
By changing the SendMessage Function's "ByVal wParam as Long" to "ByVal wParam as String", we change the search ability from first letter only, to "change-as-we-type" searching.
Here's some example code. Start a new Standard EXE project and add a ListBox (List1) and a TextBox (Text1), then paste in the following code :
option Explicit 'Start a new Standard-EXE project. 'Add a textbox and a listbox control to form 1 'Add the following code to form1: private Declare Function SendMessage Lib "User32" _ Alias "SendMessageA" (byval _ hWnd as Long, _ byval wMsg as Integer, _ byval wParam as string, _ lParam as Any) as Long Const LB_FINDSTRING = &H18F private Sub Form_Load() With List1 .Clear .AddItem "RAM" .AddItem "rams" .AddItem "RAMBO" .AddItem "ROM" .AddItem "Roma" .AddItem "Rome" .AddItem "Rommel" .AddItem "Cache" .AddItem "Cash" End With End Sub private Sub Text1_Change() List1.ListIndex = SendMessage(List1.hWnd, LB_FINDSTRING, _ Text1, byval Text1.Text) End Sub
