Searching CStrings in C++

Question

I was wondering if there is a native C++ (or STL/Boost) function which will search a CString for a specified string?

e.g.

CString strIn = "Test number 1";
CString strQuery = "num";

bool fRet = SomeFn(strIn, StrQuery);

if( fRet == true )
{
  // Ok strQuery was found in strIn
 ...

I have found a small number of functions like CompareNoCase IndexOf etc... but so far they don't really do what I want them to do (or use CLR/.Net)

Thanks!

Please be aware that `CString` is not actually a standard class in the C++ standard. — Paul de Vrieze, Oct 20 '08 at 12:06
I'm actually stunned by the fact that you didn't just look for the obvious function names "find" or "search" in CString or std::string. — Johann Gerell, Oct 20 '08 at 17:27

CString::Find() is what you want, one of the overloads does sub-string searching.

CString strIn = "test number 1";
int index = strIn.Find("num");
if (index != -1)
    // ok, found

Have you tried CString::Find?

It's not STL or boost but since you have two CString's it seems the most reasonable method to use.
