The CHECKBOX statement creates a check-box control. The control is a small rectangle (check box) that has the specified text displayed to the right. The control highlights the rectangle and sends a message to its parent window when the user selects the control. The CHECKBOX statement, which you can use only in a DIALOG or WINDOW statement, defines the text, identifier, coordinates, dimensions, and attributes of a control window. The predefined class for this control is WC_BUTTON. If you do not specify a style, the default style is BS_CHECKBOX and WS_TABSTOP.
