unicode环境下CString转为char*

最近写了一个WTL的项目，发现unicode环境下，CString转为char* 还是比较麻烦的。

CString str_ReourceText;

    //get resource text

    HWND hWndResourceText = GetDlgItem(IDC_SRC);

    int int_ReourceText=::GetWindowTextLength(hWndResourceText);

    int_ReourceText++;

    LPTSTR lpStr = str_ReourceText.GetBufferSetLength(int_ReourceText);

    ::GetWindowText(hWndResourceText, lpStr, int_ReourceText);

    char *output =NULL;
    char *name= (char *)malloc(int_ReourceText);
    CT2A ascii(str_ReourceText);

    strcpy_s(name,int_ReourceText, ascii.m_psz);

转为 utf8

// Convert to UTF8
CString str(_T("Some Unicode goodness"));
CT2A ascii(str, CP_UTF8);
TRACE(_T("UTF8: %S\n"), ascii.m_psz);

// Convert to Thai code page
CString str(_T("Some Thai text"));
CT2A ascii(str, 874);
TRACE(_T("Thai: %S\n"), ascii.m_psz);
