C++中getwindowtext的使用

在编写mfc的时候 我想用getwindowtext来得到数据 用setwindowtext来显示数据 可是运行后却说error C2039: 'GetWindowTextA' : is not a member of 'CString' 求教~~
CString csa;
CString csb;
m_a.GetWindowText (csa);
m_b.getwindowtext(csb);
int na=atoi(csa.GetBuffer(0));
csa.ReleaseBuffer();
int nb=atoi(csb.GetBuffer(0));
csb.ReleaseBuffer();
int nresult = na+nb;
char chresult [128]={0};
itoa(nresult,chresult,10);
m_aplusb.setwindowtext(chresult);
CDialog::OnOK();

CWnd *h1;
h1=GetDlgItem(IDC_STATIC1);
