The following script routine demonstrates how you can work with TListBox items (from the Borland VCL) directly from a TestComplete script using methods and properties of the Win32ListBox object. This example assumes that the application displays a form with a TListBox control on it. First, SaveItems retrieves the selected list box items and then posts them to the test log.
JavaScript, JScript
function LogSelectedItems()
{
  var p, lb, i;
  // Obtains the list box object
  p = Sys.Process("Project1");
  lb = p.Window("TForm1", "Form1").Window("TListBox", "ListBox1");
  // Goes through the list box items 
  for (i=0; i<lb.wItemCount; i++)
    // If an item is selected, ...
    if (lb.wSelected(i))
      // ... posts the item caption to the log
      Log.Message(lb.wItem(i));
}
Python
def LogSelectedItems():
  # Obtains the list box object
  p = Sys.Process("Project1")
  lb = p.Window("TForm1", "Form1").Window("TListBox", "ListBox1")
  # Goes through the list box items 
  for i in (0, lb.wItemCount-1):
    # If an item is selected, ...
    if lb.wSelected[i]:
      # ... posts the item caption to the log
      Log.Message(lb.wItem[i])VBScript
Sub LogSelectedItems
  Dim p, lb, i
  ' Obtains the list box object
  Set p = Sys.Process("Project1")
  Set lb = p.Window("TForm1", "Form1").Window("TListBox", "ListBox1")
  ' Goes through the list box items 
  For i = 0 To lb.wItemCount - 1
    ' If an item is selected, ...
    If lb.wSelected(i) Then
      ' ... posts the item caption to the log
      Log.Message(lb.wItem(i))
    End If
  Next
End Sub
DelphiScript
procedure LogSelectedItems;
var p, lb, i : OleVariant;
begin
  // Obtains the list box object
  p := Sys.Process('Project1');
  lb := p.Window('TForm1', 'Form1').Window('TListBox', 'ListBox1');
  // Goes through the list box items 
  for i := 0 to lb.wItemCount-1 do
    // If an item is selected, ...
    if lb.wSelected[i] then
      // ... posts the item caption to the log
      Log.Message(lb.wItem[i]);
end;
C++Script, C#Script
function LogSelectedItems()
{
  var p, lb, i;
  // Obtains the list box object
  p = Sys["Process"]("Project1");
  lb = p["Window"]("TForm1", "Form1")["Window"]("TListBox", "ListBox1");
  // Goes through the list box items 
  for (i=0; i<lb["wItemCount"]; i++)
    // If an item is selected, ...
    if (lb["wSelected"](i))
      // ... posts the item caption to the log
      Log["Message"](lb["wItem"](i));
}
