If you are using CString, then use CString::Mid()[^].

// If you are using CString.
CString csString = _T("Visual C++ is Great!!!");
CString csSubStr = csString.Mid( 0, 10 );

If you are using std::string then, you can use string::substr[^].

// If you use std::string.
std::string sString = _T("Visual C++ is Great!!!");
std::string sSubStr = sString.substr( 0, 10 );

Regards, Jijo.

Using CString... First use CString::Find and then CString::Mid to extract substring. Using std::string First use std::string::find and then std::string::substr.

Quite easy to use MFC in console application. First link to MFC libraries and then call AfxWinInit and a global CWinApp instance, sample code...

CWinApp app; // global
// initialize MFC and print error on failure, inside main function
if (!AfxWinInit(::GetModuleHandle(NULL), NULL, ::GetCommandLine(), 0))
{
// TODO: change error code to suit your needs
cerr << "Fatal Error: MFC initialization failed" << endl;
return 1;
}

And if you are going to use MFC just for this purpose, I would discourage you from doing so, instead use std::string.

Then you can use strncpy() or memcpy().
