'SetWindowTextW' : is not a member of 'ATL::CStrin

error C2039: 'SetWindowTextW' : is not a member of 'ATL::CStringT '

对应错误行数：m_Status.SetWindowText(_T("AAAAAAAA"));

错误原因：

m_Status 是Cstring类型，指向的是Static控件，没有SetWindowTextW方法。

修改方法：

把m_Status类型改成CStatic m_Status; 

void CThroughPutDlg::DoDataExchange(CDataExchange* pDX)
{
 CDialog::DoDataExchange(pDX);

 //添加此行
 DDX_Control(pDX, IDC_STATIC_ST, m_Status);
}
