CStringT::CollateNoCase
Compares two strings using the generic-text function _tcscoll.
int CollateNoCase(
PCXSTR psz
) const throw();
Parameters
- psz
The other string used for comparison.
Return Value
Zero if the strings are identical (ignoring case), < 0 if this CStringT object is less than psz (ignoring case), or > 0 if this CStringT object is greater than psz (ignoring case).
Remarks
The generic-text function _tcscoll, which is defined in TCHAR.H, maps to either stricoll, wcsicoll, or _mbsicoll, depending on the character set that is defined at compile time. Each function performs a case-insensitive comparison of the strings, according to the code page currently in use. For more information, see strcoll, wcscoll, _mbscoll, _strcoll_l, _wcscoll_l, _mbscoll_l.
Example
// typedef CStringT<TCHAR, StrTraitATL<TCHAR, ChTraitsCRT<TCHAR>>> CAtlString;
CAtlString str1 = _T("Co-Op");
CAtlString str2 = _T("con");
int n;
// Collation uses language rules, such as ignoring dashes.
// NoCase version ignores case.
n = str1.CollateNoCase(str2);
ASSERT(n < 0);
// Comparison is a strict ASCII comparison with no language rules
// but still ignores case in NoCase version.
n = str1.CompareNoCase(str2);
ASSERT(n < 0);
