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
);

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;
