為了方便說明，我們假定創(chuàng)建了基于對(duì)話框的MFC應(yīng)用程序，第一個(gè)組框?yàn)?分?jǐn)?shù)",內(nèi)有四個(gè)單選按鈕:"100","90","80","70".ID分別為IDC_RADIO1,IDC_RADIO2,IDC_RADIO3,IDC_RADIO4;IDC_RADIO1的Group屬性為TRUE.第二個(gè)組框?yàn)?加權(quán)",內(nèi)有四個(gè)復(fù)選按鈕:"10","9","8","7",ID分別為IDC_CHECK1,IDC_CHECK2,IDC_CHECK3,IDC_CHECK4;IDC_CHECK1的Group屬性為TRUE.
判斷哪個(gè)單選按鈕按下:第一種方式:給IDC_RADIO1關(guān)聯(lián)一個(gè)int型變量m_radio,首先調(diào)用UpdateData(TRUE);然后判斷IDC_RADIO1的值
                           switch(m_radio)
                            {
                                   case 0:
                                            MessageBox(_T("100"));
                                            break;
                                   case 1:
                                            MessageBox(_T("90"));
                                            break;
                                   case 2:
                                            MessageBox(_T("80"));
                                            break;
                                   case 3:
                                            MessageBox(_T("70"));
                                            break;
                            }
          第二種方式:
                            switch(GetCheckedRadioButton(IDC_RADIO1,IDC_RADIO4))
                            {
                                   case IDC_RADIO1:
                                            MessageBox(_T("100"));
                                            break;
                                   case IDC_RADIO2:
                                            MessageBox(_T("90"));
                                            break;
                                   case IDC_RADIO3:
                                            MessageBox(_T("80"));
                                            break;
                                   case IDC_RADIO4:
                                            MessageBox(_T("70"));
                                            break;
                            }
判斷哪些復(fù)選按鈕按下:第一種方式:給IDC_CHECK1~IDC_CHECK4分別關(guān)聯(lián)一個(gè)BOOL型變量m_check1~m_check4,首先調(diào)用UpdateData(TRUE);然后判斷各個(gè)變量的值;
                              if(m_check1==TRUE)
                                         str+="10";
                              if(m_check2==TRUE)
                                         str+="9";
                              if(m_check3==TRUE)
                                         str+="8";
                              if(m_check4==TRUE)
                                         str+="7";
                              MessageBox(str);
         第二種方式:給IDC_CHECK1~IDC_CHECK4分別關(guān)聯(lián)一個(gè)CButton型變量m_check1~m_check4判斷各個(gè)變量的值;
                              if(m_check1.GetCheck()==1)
                                         str+="10";
                              if(m_check2.GetCheck()==1)
                                         str+="9";
                              if(m_check3.GetCheck()==1)
                                         str+="8";
                              if(m_check4.GetCheck()==1)
                                         str+="7";
                              MessageBox(str);
         第三種方式:利用GetDlgItem()函數(shù)
                              CButton *pBtn1=(CButton*)GetDlgItem(IDC_CHECK1);
                              CButton *pBtn3=(CButton*)GetDlgItem(IDC_CHECK2);
                              CButton *pBtn3=(CButton*)GetDlgItem(IDC_CHECK3);
                              CButton *pBtn4=(CButton*)GetDlgItem(IDC_CHECK4);
                              if(pBtn1->GetCheck()==1)
                              str+="10";
                              if(pBtn2->GetCheck()==1)
                              str+="9";
                              if(pBtn3->GetCheck()==1)
                              str+="8";
                              if(pBtn4->GetCheck()==1)
                              str+="7";
         第四種方法:利用IsDlgButtonChecked()函數(shù)
                              if(BST_CHECKED == IsDlgButtonChecked( IDC_CHECK1 ))
                                           str+="10";
                              if(BST_CHECKED == IsDlgButtonChecked( IDC_CHECK2 ))
                                           str+="9";
                              if(BST_CHECKED == IsDlgButtonChecked( IDC_CHECK3 ))
                                           str+="8";
                              if(BST_CHECKED == IsDlgButtonChecked( IDC_CHECK4 ))
                                           str+="7";
                              MessageBox(str);
