我用VC编的界面，上面放有两组RADIO BUTTON的单选按钮，第一组是IDC_RADIO1，IDC_RADIO2，IDC_RADIO3，IDC_RADIO4，第二组是IDC_RADIO5，IDC_RADIO6，IDC_RADIO7，已经将IDC_RADIO1和IDC_RADIO5的Group属性选中。但是每次的程序计算一次后，不能重新选择按钮进行第二次运算，比如，我第一次选择的是IDC_RADIO1和IDC_RADIO5，计算完成后，我想换成IDC_RADIO1和IDC_RADIO6的条件进行计算，可是这是程序就会出错终止。请问这个问题该怎么解决呢？m_typearray变量关联的是IDC_RADIO5，IDC_RADIO6，IDC_RADIO7，m_arth变量关联的是IDC_RADIO1，IDC_RADIO2，IDC_RADIO3，IDC_RADIO4。
