The CONTAINER statement creates a container control within a dialog window. The container control is a visual component that holds objects. The CONTAINER statement defines the identifier, coordinates, dimensions, and attributes of a container control. The predefined class for this control is WC_CONTAINER. If you do not specify a style, the default style is WS_TABSTOP, WS_VISIBLE, and CCS_SINGLESEL.
Example
This example creates a container control at position (30,30) within the dialog window. The container has a width of 70 character units and a height of 25 character units. Its resource ID is 301. The default style CCS_SINGLESEL has been overridden by the style specification CCS_MULTIPLESEL. The default styles WS_TABSTOP and WS_GROUP are both in effect, though only the latter is specified.
