[JScript] In JScript, you can handle the events defined by a class, but you cannot define your own.
The event handler receives an argument of type EventArgs.
When you change the focus by using the keyboard (TAB, SHIFT+TAB, and so on), by calling the Select or SelectNextControl methods, or by setting the ContainerControl.ActiveControl property to the current form, focus events occur in the following order:
When you change the focus by using the mouse or by calling the Focus method, focus events occur in the following order:
If the CausesValidation property is set to false, the Validating and Validated events are suppressed.
Note The GotFocus and LostFocus events are low-level focus events that are tied to the WM_KILLFOCUS and WM_SETFOCUS Windows messages. Typically, the GotFocus and LostFocus events are only used when updating UICues. The Enter and Leave events should be used for all controls except the Form class, which uses the Activated and Deactivate events. For more information about the GotFocus and LostFocus events, see the WM_SETFOCUS and WM_KILLFOCUS topics in the Keyboard Input Reference section of the Platform SDK Documentation in the MSDN Library.
CAUTION Do not attempt to set focus from within the LostFocus event handler. Doing so can cause your application or the operating system to stop responding. For more information about the LostFocus event, see the WM_KILLFOCUS topic in the Keyboard Input Reference section, and the Message Deadlocks topic in the Messages and Message Queues section of the Platform SDK Documentation in the MSDN Library.
