Calendar and Diary
Visual FoxPro includes a simple calendar and diary accessory which stores
the user's appointments. It appears as a separate window and is neither as impressive
nor as flexible as the ActiveX calendars such as mscal.ocx. It is however
very much simpler to use and can be distributed freely with your FoxPro executable.
Another advantage is that it is self-contained and does not rely on your users having
the correct version of the various external DLLs that are required by
the more complex ActiveX solutions. This means that you can guarantee
that the calendar will keep on working, regardless of what other software your
users might be installing or removing.
Using the Calendar
The calendar no longer appears as an option on any of the FoxPro menus.
The only way to make it appear is through program code. You can write code
to call the calendar from a command button or from a menu option or
perhaps from a hot key:
The date selected by the user is stored in the FoxPro system variable
_DIARYDATE. You can read and write to this variable whether or not the
Calendar window is visible. If you set the value of _DIARYDATE:
then the Calendar will (at least in the UK) display the month of December
2006 with the 25th selected and the events of the 25th visible.
The events for each day are stored in the Data field of the FoxUser table.
The Calendar application will still work without the resource file but an
unpleasant warning message is displayed before the calendar appears.
Because the Calendar is a window within FoxPro you can use the
standard functions to inspect its status. For example:
will return .T. if the Calendar window
the Calendar tool has been available since version 2.00 of FoxPro for
