void CTestDlg::OnClickedButton2()
{

 int num1,num2,num3;
 CString str1,str2,str3;
 ::SendMessageW(GetDlgItem(IDC_EDIT1)->m_hWnd,WM_GETTEXT,10,(LPARAM)str1.GetBuffer(256));
 ::SendMessageW(m_edit2.m_hWnd,WM_GETTEXT,10,(LPARAM)str2.GetBuffer(256));
 num1 = _wtoi(str1);
 num2 = _wtoi(str2);
 num3 = num1 + num2;
 str3.Format(L"%d",num3);
 m_edit3.SendMessageW(WM_SETTEXT,10,(LPARAM)str3.GetBuffer(0));
 str1.ReleaseBuffer();
 str2.ReleaseBuffer();
 str3.ReleaseBuffer();
