Closes Data Source.
Boolean ObjectName. CloseSource()
None.
Boolean.
TRUE indicates success. FALSE indicates failure.
When an error occurs and IfThrowException property is TRUE, an exception will be thrown.
When FALSE is returned or an exception is thrown, check ErrorCode property and ErrorString property for error information.
CloseSource() is called automatically if necessary, since Dynamic (Web) TWAIN has built-in Wizard Mode.
