CString into string

[eranga262154]

Hi all,

What is the easiest way to convert a CString into a standard C++ sting.

Thanks

CString theCString = "Hello World!";
std::string yourString(theCString.GetString());

Thanks, I've done it in this way also.

string strRTF = (LPCSTR)ss;

Not given any compilation error. But when I try this,

cout << strRTF;

It gives the following compile error. No idea why it is impossible.

binary '<<' : no operator found which takes a right-hand operand of type 'std::string' (or there is no acceptable conversion)

Try preceding everything with std::.

I've already test it. Use the namespaces as well. But no luck. Amazing thing is,

		if(m_rtfCtrl.CreateEx(WS_EX_APPWINDOW, WS_BORDER|ES_MULTILINE, CRect(10,10,200,200), &x , 1))
		{
			CString ss;
			CFile rtfFile;
			BOOL err = rtfFile.Open("G:\\Work On\\CPP\\RTFControl\\TestFile.rtf", CFile::modeReadWrite, NULL);

			int iLength = rtfFile.GetLength();// Data length
			char *pBuffer = new char[iLength];// Data buffer

			rtfFile.Read(pBuffer, iLength);
			CString rtf(pBuffer);

			m_rtfCtrl.SetWindowText(rtf);
			m_rtfCtrl.GetWindowText(ss);

			std::cout << ss << std::endl;

			// CString into string
			std::string strRTF(ss.GetString());
			

			std::cout << strRTF << std::endl;

		}

In my above code, fist cout works fine. The second cout not works.

Try:

std::string strRTF((char*)ss.GetString());

It also don't work chem. I found that strRTF should be null-terminated string. So,

cout << strRTF.c_str();

gives the correct string. But why is that, cout is the standard iostream object, so null-terminated is required?

[chemicalNova]

Strings that you store in a standard string object.. are still strings. They need to be null terminated.. how else would you know where they end?

Perhaps this works..

CString str = "Hello World!\0";
std::string str2((char*)str.GetString());

std::cout << str2;

chem

Yes, on this code also I have null-terminated the string str2.
