compare string

[dellthinker]

Hi all, would anyone happen to know the equivalent of comparing a string declared variable or character? Sort of like strstr or strcmp, i just cant find which one is used for C-like string. Thanx in advance!

string somecode; strstr and strcmp does not work for string unless its declared as a char I dont know what to search for because i've already tried Google and nothing came up that refers to what im looking for.

Stuff like this? strcmp(str.c_str(), str2.c_str()); wcscmp(str.c_str(), str2.c_str()); operator== ( <string> )[^] basic_string::compare[^] Mark

You may try the following CString s1, s2; if ( s1.GetLength() != s2.GetLengtth() ) // Not equal else { for( int i = 0; i < s1.GetLength(); i++ ) { if ( (Byte) s1.GetAt(i) != (BYTE) s2.GetAt(i) ) break; } if ( i != s1.GetLength() ) // String Not equal. else // String equal. } Hope this will help u, if ur string length is small.

Try using 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.

"string" class has overloaded "==" operator. You can directly use the == operator. Eg: string s1("hi"); string s2("hello"); if (s1==s2) { .... } else { .... }

Why do people continue to recommend using CString methods when the OP is using a string object? It just doesn't make sense. :rolleyes: Furthermore, why would you not just use CString's Compare(), CompareNoCase(), or == operator?
