About Support

TestComplete can recognize Win32 ScrollBar controls in Windows applications. It provides special properties and methods that let you retrieve the controls data and simulate user actions on the controls (see below).

For information on how to use these properties and methods in tests, see Working With Scroll Bar Controls.


In order for TestComplete to be able to work with your controls as with Win32 ScrollBar controls, the control’s class name must be specified in the Win32 Controls and Windows | Scroll bar group of your project’s Object Mapping options. By default, this group contains the following item:

  • *ScrollBar*
Note: The asterisk (*) wildcards specify variable parts of class names.

You can also command the test engine to recognize custom controls as Win32 ScrollBar controls. See below for information about this.

Recognizing Custom Controls

To command TestComplete to recognize your custom controls as Win32 ScrollBar controls:

  1. Open your project’s Object Mapping options.

  2. Add the control’s class name to the Win32 Controls and Windows | Scroll bar group.

    If you do not know the control’s name, you can ask the control’s developers, or you can view the control’s WndClass property in the Object Browser panel. As an alternative, you can click Add From Screen and select your custom control on screen. TestComplete will retrieve the control’s class name and add it to the selected mapping group automatically. For detailed information, see Object Mapping.

Once the control is mapped, it gets all the properties, methods and actions specific to the Win32 ScrollBar control.

If the specified custom control does not fit the control’s type, then it may not properly respond to commands that TestComplete sends, so recording or playing back user actions over the tested control will cause errors.


When testing Win32 ScrollBar controls, you can use properties and methods specific to these controls, as well as properties and methods that TestComplete applies to tested objects, onscreen objects and window objects. For the full list of available properties and methods, see the following topics:
