Determines whether a dialog element is checked (selected) or not.

For list view items and tree view items, the control must have the "Check boxes (c)" STYLE, whereupon check boxes are displayed for each item.

For date and time picker (DTP) controls, the control must have the "Allow 'no value' (n)" STYLE, in which case the control has a check box, indicating whether a value has been set. The program should check for this before trying to retrive the control's TIME value. On update, the CHECKED attribute is set implicitly when a value is assigned.

Applies to	Date/time picker control, list view item, menu item, radio button control, signal, table control, toggle button control, tool bar item, tree view item.
Data Type	I4
