DatePicker SET DAYS OFF ( objectName {; dayType ; ptrDaysOffArray} )

Parameter	Type	Description
objectName	Text	Name of subform object
dayType	Longint	Types of days off
ptrDaysOffArray	Pointer	Pointer to date or Boolean array of days off

Description

The DatePicker SET DAYS OFF command is used to set the days off to appear in the DatePicker calendar. These days are displayed in bold and italic and remain selectable for the user.

The objectName parameter specifies the instance of the subform to which the command must be applied. In this parameter, you must pass the name of a subform object displayed in the current form.

This command can be used to set either recurrent weekly or yearly days off as well as occasional holidays. You specify the type of days off set via the dayType parameter:

0 = Days off occurring weekly (by default, Saturday and Sunday)
1 = Days off that occur every year (such as January 1st or December 25th)
2 = Occasional holidays, set for a single year

You set the holidays by creating a array and by passing a pointer to this array as the ptrDaysOffArray parameter. The type of array depends on the value passed in dayType:

If you pass 0 in dayType (weekly days off), in ptrDaysOffArray you must pass a pointer to a Boolean array made up of 7 elements. Each element set to True indicates a weekly day off.
If you pass 1 or 2 in dayType (yearly or occasional days off), in ptrDaysOffArray you must pass a pointer to a Date array. In this array, each element must contain a valid date, indicating a day off. The dates must be expressed in the default format corresponding to the system language. If you passed 1 in dayType (recurrent days), the year is ignored; you can pass any value.

Example 1

Designation of Friday as the weekly day off (instead of Saturday and Sunday by default):

 ARRAY BOOLEAN($arrbDaysOff;7)

  //By default, all the elements of a Boolean array are False; thus it is not necessary to add initialization code

 $arrbDaysOff{Friday}:=True

 DatePicker SET DAYS OFF("mycalendar";0;->$arrbDaysOff)

Example 2

Designation of occasional holidays:

 ARRAY DATE($arrdUniqueDays;0)

  //The year is taken into account

 APPEND TO ARRAY($arrdUniqueDays;!02/15/2008!)

 APPEND TO ARRAY($arrdUniqueDays;!02/12/2009!)

 APPEND TO ARRAY($arrdUniqueDays;!02/17/2010!)

 DatePicker SET DAYS OFF(1;->$arrdUniqueDays)
