LPWSTR substring?

[ting668]

HI~ How to search a substring from LPWSTR? Also I cannot extract a character like string class e.g I cannot do this: LPWSTR a_string = _T("abcdef") if (a_string[2] == 'c'){...} How to extract a character is the string is LPWSTR type? Thanks

LPWSTR a_string = _T("abcdef"); if (a_string[2] == (WCHAR)'c'){...}

LPCTSTR SubString( LPCTSTR lpExpression, // [in] Pointer to a string to extract the substring from ULONG nStart, // [in] Starting point LONG nLength = -1 ) // [in] how far to go from the startig point, use -1 to go the end of lpExpression { if( nLength < 0 ) nLength = strlen(lpExpression) - nStart; ULONG nPos = 0; PTCHAR lpResult = new TCHAR[512]; for( ULONG i = nStart; i < (ULONG)(nStart+nLength); i++ ) { // put the current char from lpExpression into lpResult lpResult[nPos++] = lpExpression[i]; } // add the null byte to lpResult; lpResult[nPos] = '\0'; // return the substring return lpResult; }
