Note: To learn how to simulate user actions over list box controls in web applications, see Working With List Box Controls in Web Applications.

While testing list box controls, you can use specific properties and methods of the corresponding program object to perform certain actions and obtain data stored in controls. You can call these methods and properties from your keyword tests, as well as from scripts. This topic describes how to work with the needed properties and methods from your scripts. However, when testing a control from your keyword test, you can use the same methods and properties calling them from keyword test operations. For more information, see Keyword Tests Basic Operations.

When testing a list box control, you may need to know the total number of items that the control contains. The Win32ListBox object provides a number of properties, which let you work with standard Windows list box controls. To determine the total number of list box’s items, you can use the wItemCount property, which belongs to the Win32ListBox object.

The following code snippet posts the total number of items to the log:

JavaScript, JScript

JavaScript, JScript

function Main()
{
  var p, w, ListBox;

  // Obtain list box object
  p = Sys.Process("wordpad");
  Sys.Keys("~i[Enter]");
  w = p.Window("#32770", "Date and Time");
  ListBox = w.Window("ListBox", "", 1);

  // Post total number of items to the log
  Log.Message("Number of items: " + ListBox.wItemCount);
}

Python

def Main(): 

  # Obtain list box object 
  p = Sys.Process("wordpad")
  Sys.Keys("~i[Enter]")
  w = p.Window("#32770", "Date and Time")
  ListBox = w.Window("ListBox", "", 1) 

  # Post total number of items to the log 
  Log.Message("Number of items: " + ListBox.wItemCount)

VBScript

Sub Main
  Dim p, w, ListBox

  ' Obtain list box object
  Set p = Sys.Process("wordpad")
  Sys.Keys "~i[Enter]"
  Set w = p.Window("#32770", "Date and Time")
  Set ListBox = w.Window("ListBox", "", 1)

  ' Post total number of items to the log
   Log.Message("Number of items: " & ListBox.wItemCount)
End Sub

DelphiScript

procedure Main;
var p, w, ListBox : OleVariant;
begin
  // Obtain list box object
  p := Sys.Process('wordpad');
  Sys.Keys('~i[Enter]');
  w := p.Window('#32770', 'Date and Time', 1);
  ListBox := w.Window('ListBox', '', 1);

  // Post total number of items to the log
  Log.Message('Number of items: ' + aqConvert.VarToStr(ListBox.wItemCount));
end;

C++Script, C#Script

function Main()
{
  var p, w, ListBox;

  // Obtain list box object
  p = Sys["Process"]("wordpad");
  Sys.Keys("~i[Enter]");
  w = p["Window"]("#32770", "Date and Time", 1);
  ListBox = w["Window"]("ListBox", "", 1);

  // Post total number of items to the log
  Log.Message("Number of items: " + ListBox.wItemCount);
}
