CString::Compare
int Compare( LPCTSTR lpsz ) const;
Return Value
Zero if the strings are identical, < 0 if this CString object is less than lpsz, or > 0 if this CString object is greater than lpsz.
Parameters
lpsz
The other string used for comparison.
Remarks
Compares this CString object with another string using the generic-text function _tcscmp. The generic-text function _tcscmp, which is defined in TCHAR.H, maps to either strcmp, wcscmp, or _mbscmp depending on the character set that is defined at compile time. Each of these functions performs a case-sensitive comparison of the strings, and is not affected by locale. For more information, seestrcmp, wcscmp, _mbscmp in the Run-Time Library Reference.
Example
The following example demonstrates the use of CString::Compare.
// example for CString::Compare
CString s1( "abc" );
CString s2( "abd" );
ASSERT( s1.Compare( s2 ) == -1 ); // Compare with another CString.
ASSERT( s1.Compare( "abe" ) == -1 ); // Compare with LPTSTR string.

CString::Find
int Find( TCHAR ch ) const;
int Find( LPCTSTR lpszSub ) const;
int Find( TCHAR ch, int nStart ) const;
int Find( LPCTSTR pstr, int nStart ) const;
Return Value
The zero-based index of the first character in this CString object that matches the requested substring or characters; -1 if the substring or character is not found.
Parameters
ch
A single character to search for.
lpszSub
A substring to search for.
nStart
The index of the character in the string to begin the search with, or 0 to start from the beginning. The character at nStart is excluded from the search if nStart is not equal to 0.
pstr
A pointer to a string to search for.
Remarks
Searches this string for the first match of a substring. The function is overloaded to accept both single characters (similar to the run-time function strchr) and strings (similar to strstr).
Example
// First example demonstrating
// CString::Find ( TCHAR ch )
CString s( "abcdef" );
ASSERT( s.Find( 'c' ) == 2 );
ASSERT( s.Find( "de" ) == 3 );
// Second example demonstrating
// CString::Find( TCHAR ch, int nStart )
CString str("The stars are aligned");
int n = str.Find('e', 5);
ASSERT(n == 12);
