Q: How to use 'CString' in non-MFCapplications?
A: In most cases, you don't need to do that. In order to use 'CString'you have to statically or dynamically link your application to theentireMFC. This would not only increase the size of your executable file, the numberof its dependencies,
but also makes your program non-portable (especially if itis a Console application).
The recommended solution is to use the Standard C++ Class 'std::string'. It isas powerful as 'CString', is portable, using it does not imply adding a hugeamount of things you don't need to your project and last, but not least, it ispartof the programming
language.
This being said, if you still want to use 'CString' in your non-MFCapplication, here it is whar you have to do:
- Include 'afx.h' in one of your main headers
- Open the menu 'Project -> Settings'. On the 'General' register of the settings dialog box choose 'Use MFC in a Shared DLL' or 'Use MFC in a Static Library' from the dropdown box called 'Microsoft Foundation Classes'.
- Rebuild your project.
A simple sample of a console application using 'CString'looks like this:
Code:
#include<afx.h>
#include<iostream>
intmain()
{
CString s("Hello");
std::cout << s.GetBuffer(0) << std::endl;
return 0;
}

方法二：从vs2003开始，你可以使用 <atlstr.h>
Starting VS 2003, you can useCString in non-MFC applications by including header atlstr.h:
Code:
#include <atlstr.h>
A sample console application withCString:
Code:
#include <atlstr.h>
#include <iostream>
int main ()
{
CString strTest (_T("This is aCString in a console application!"));
#ifdef UNICODE
std::wcout << (LPCTSTR)strTest;
#else
std::cout << (LPCTSTR)strTest;
#endif
return 0;
}
You canalso use CStringA as a ANSI string class, and CStringW as a wide-characterstring class.
方法三：可以使用 boost 中的 string
BoostString Algorithms Library
