EnumCalendarInfo (Windows Embedded CE 6.0)

1/6/2010

This function enumerates the calendar information by calling an application-defined callback function. It passes the callback function a pointer to a string buffer that contains the requested calendar information. This continues until either the last applicable calendar is found or the callback function returns FALSE.

Syntax

BOOL EnumCalendarInfo(
  CALINFO_ENUMPROC lpCalInfoEnumProc, 
  LCID Locale, 
  CALID Calendar, 
  CALTYPE CalType
);

The CALTYPE constants define particular pieces of calendar information. The following table shows CALTYPE constants that are mutually exclusive — that is, they cannotbe used in combination with each other in a function call.

Type	Description
CAL_ICALINTVALUE	An integer value indicating the calendar type of the alternate calendar.
CAL_IYEAROFFSETRANGE	One or more null-terminated strings that specify the year offsets for each of the era ranges. The last string has an extra terminating null character.
CAL_SABBREVDAYNAME1	Abbreviated native name of the first day of the week.
CAL_SABBREVDAYNAME2	Abbreviated native name of the second day of the week.
CAL_SABBREVDAYNAME3	Abbreviated native name of the third day of the week.
CAL_SABBREVDAYNAME4	Abbreviated native name of the fourth day of the week.
CAL_SABBREVDAYNAME5	Abbreviated native name of the fifth day of the week.
CAL_SABBREVDAYNAME6	Abbreviated native name of the sixth day of the week.
CAL_SABBREVDAYNAME7	Abbreviated native name of the seventh day of the week.
CAL_SABBREVMONTHNAME1	Abbreviated native name of the first month of the year.
CAL_SABBREVMONTHNAME2	Abbreviated native name of the second month of the year.
CAL_SABBREVMONTHNAME3	Abbreviated native name of the third month of the year.
CAL_SABBREVMONTHNAME4	Abbreviated native name of the fourth month of the year.
CAL_SABBREVMONTHNAME5	Abbreviated native name of the fifth month of the year.
CAL_SABBREVMONTHNAME6	Abbreviated native name of the sixth month of the year.
CAL_SABBREVMONTHNAME7	Abbreviated native name of the seventh month of the year.
CAL_SABBREVMONTHNAME8	Abbreviated native name of the eighth month of the year.
CAL_SABBREVMONTHNAME9	Abbreviated native name of the ninth month of the year.
CAL_SABBREVMONTHNAME10	Abbreviated native name of the tenth month of the year.
CAL_SABBREVMONTHNAME11	Abbreviated native name of the eleventh month of the year.
CAL_SABBREVMONTHNAME12	Abbreviated native name of the twelfth month of the year.
CAL_SABBREVMONTHNAME13	Abbreviated native name of the thirteenth month of the year, if it exists.
CAL_SCALNAME	Native name of the alternate calendar.
CAL_SDAYNAME1	Native name of the first day of the week.
CAL_SDAYNAME2	Native name of the second day of the week.
CAL_SDAYNAME3	Native name of the third day of the week.
CAL_SDAYNAME4	Native name of the fourth day of the week.
CAL_SDAYNAME5	Native name of the fifth day of the week.
CAL_SDAYNAME6	Native name of the sixth day of the week.
CAL_SDAYNAME7	Native name of the seventh day of the week.
CAL_SERASTRING	One or more null-terminated strings that specify each of the Unicode codepoints specifying the era associated with the given CAL_IYEAROFFSETRANGE. The last string has an extra terminating null character. See example below.
CAL_SLONGDATE	Long date formats for this calendar type.
CAL_SMONTHNAME1	Native name of the first month of the year.
CAL_SMONTHNAME2	Native name of the second month of the year.
CAL_SMONTHNAME3	Native name of the fifth month of the year.
CAL_SMONTHNAME4	Native name of the fourth month of the year.
CAL_SMONTHNAME5	Native name of the fifth month of the year.
CAL_SMONTHNAME6	Native name of the sixth month of the year.
CAL_SMONTHNAME7	Native name of the seventh month of the year.
CAL_SMONTHNAME8	Native name of the eighth month of the year.
CAL_SMONTHNAME9	Native name of the ninth month of the year.
CAL_SMONTHNAME10	Native name of the tenth month of the year.
CAL_SMONTHNAME11	Native name of the eleventh month of the year.
CAL_SMONTHNAME12	Native name of the twelfth month of the year.
CAL_SMONTHNAME13	Native name of the thirteenth month of the year, if it exists.
CAL_SSHORTDATE	Short date formats for this calendar type.

If the native name for the day of the week or for a month is an empty string, that name is identical to the name given in the corresponding locale information and therefore is not duplicated here.

The CAL_IYEAROFFSETRANGE and CAL_SERASTRING values vary in format depending on the type of optional calendar. The following example shows the values for these types (for each supported alternate calendar type) along with the formula for how to use the CAL_IYEAROFFSETRANGE value to compute the correct year given the Gregorian current year value Y:

CAL_ICALINTVALUE = "1"
CAL_IYEAROFFSETRANGE = ""
CAL_SERASTRING = ""
CAL_ICALINTVALUE = "2"
CAL_IYEAROFFSETRANGE = ""
CAL_SERASTRING = ""
CAL_ICALINTVALUE = "3"
CAL_IYEAROFFSETRANGE = "1989\01926\01912\01868\0"
CAL_SERASTRING = "Ux337B\0Ux337C\0Ux337D\0Ux337E\0"
if (Y>=1989) { Y = (Y-1989)+1; } 
if (Y>=1926 && Y<1989) { Y = (Y-1926)+1; } 
if (Y>=1912 && Y<1926) { Y = (Y-1912)+1; }
if (Y>=1868 && Y<1912) { Y = (Y-1868)+1; } 
if (Y<1868) { Y = Y; } 
CAL_ICALINTVALUE = "4"
CAL_IYEAROFFSETRANGE = "1912\0"
CAL_SERASTRING = "Ux4E2D\0Ux83EF\0Ux6C11\0Ux570B\0"
if (Y>=1912) { Y = (Y-1912)+1; } 
if (Y<1912) { Y = Y; }
CAL_ICALINTVALUE = "5"
CAL_IYEAROFFSETRANGE = "2333\0"
CAL_SERASTRING = ""
Y = Y+2333;
