istream 之 getline
想让IO流支持UNICODE ，这么写代码。为何跑起来，一闪而过？求解，代码如下，console application 选择支持MFC。

int _tmain(int argc, TCHAR* argv[], TCHAR* envp[])
{
int nRetCode = 0;

// initialize MFC and print and error on failure
if (!AfxWinInit(::GetModuleHandle(NULL), NULL, ::GetCommandLine(), 0))
{
// TODO: change error code to suit your needs
cerr << _T("Fatal Error: MFC initialization failed") << endl;
nRetCode = 1;
}
else
{
// TODO: code your application's behavior here.
locale("chs");

vector<wstring> strColl;
vector<wstring>::iterator iter;
vector<wstring>::const_iterator const_iter;

TCHAR buffer[2048];
wcout << "Enter a string: ";

while (wcin.getline(buffer, sizeof(buffer)-1))
{
wcout << "string== " << buffer << endl;
strColl.push_back(buffer);
}
wcout << "print vector<string>: \n";
for (const_iter = strColl.begin(); const_iter != strColl.end(); ++const_iter)
{
wcout << (*const_iter).c_str() <<"\n";
}

wcout << endl;

单步调试下呢。
