Answer / rainz

The use of this function is to initialize data in a dialog box, or to retrieve and valid the same data.
Before the dialog is visible, the UpdateData (bSaveAndValidate) ,has bSaveAndValidate set as False(dialog initialization),but as soon as the "OK" button code gets executed "bSaveAndValidate" is set to true.(data retrieval)

Answer / suresh

UpdateData(): By default the parameter is FALSE; Which means
it is transfering the variables to controls;
UpdateData(TRUE): data Flowing from controls to varibles;

Answer / arvin

UpdateData(TRUE) indicate dialog box is being initialized
UpdateData(FALSE) indicates data is being retrieved from the
dialog box.
