大致是这样

CString-string：

CString str1;

m_editUsername.GetWindowTextW(str1);

char *chr1 = new char[str1.GetLength() + 1];

WideCharToMultiByte(CP_ACP, 0, str1.GetBuffer(), -1, chr1, str1.GetLength() + 1, NULL, NULL);

string tmp1 = chr1;

string-CStirng:

CString str;（注意：不能写成CString str=userID.c_str();)

str = userID.c_str();

AfxMessageBox(str);
