EnumDateFormatsProcEx

The EnumDateFormatsProcEx function is an application defined–callback function used with the EnumDateFormatsEx function. It receives a pointer to a buffer containing a date format string and a calendar identifier (CALID). The DATEFMT_ENUMPROCEX type defines a pointer to this callback function. EnumDateFormatsProc is a placeholder for the application defined–function name.

BOOL CALLBACK EnumDateFormatsProcEx (
  LPTSTR lpDateFormatString,  // date format string
  CALID  CalendarID           // calendar identifier
);

Parameters

[in] Pointer to a buffer containing a null-terminated date format string. This string is a long or short date format, depending on the value of the dwFlags parameter passed to EnumDateFormatsEx.

Remarks

An EnumDateFormatsProcEx function can carry out any desired task. An application registers an EnumDateFormatsProcEx function by passing its address to the EnumDateFormatsEx function.

The date format strings are translated from Unicode to ANSI, for the ANSI version of this function, based on the default ANSI code page for the LCID. However, if LOCALE_USE_CP_ACP is specified, the translation is done using the system default ANSI code page.

Requirements

  Windows NT/2000: Requires Windows 2000.
  Windows 95/98: Requires Windows 98.
  Header: Declared in Winnls.h; include Windows.h.
