//   DESCRIPTION: Dialog window implementation functions. These functions implement
//                the Siemens OptiSet MWI send and delete message operations.
//                These functions are called upon user selection on command buttons
//                on Dialog boxes. The MWI send and delete algorithm is implemented 
//                here. If cut and pasting code, you may need to remove Windows specific
//                code (cursor, logging, callback function types, dialog box etc...).
