The date and time picker control (CDateTimeCtrl) implements an intuitive and recognizable method of entering or selecting a specific date. The main interface of the control is similar in functionality to a combo box. However, if the user expands the control, a month calendar control appears (by default), allowing the user to specify a particular date. When a date is chosen, the month calendar control automatically disappears.
Note To use both the CDateTimePicker and CMonthCalCtrl classes in your project, you must include AFXDTCTL.H, usually in your project's STDAFX.H file.
