作一个添加记录的程序
代码如下：运行是老是跳出对话框It is not allow to add records to the datasource为什么？

void CadminsView::OnRecordAdd()
{
    CInsert *DIALOG2=new CInsert();
    if(DIALOG2->DoModal()==IDOK)
    {if(m_pSet->CanAppend())
    {m_pSet->AddNew();
    m_pSet->m_biao2name=DIALOG2->name;
    m_pSet->m_biao2brand=DIALOG2->brand;
    m_pSet->m_biao2size=DIALOG2->size;
    m_pSet->m_biao2price=atof(DIALOG2->price.GetBuffer(0));
    m_pSet->m_biao2place=DIALOG2->place;
    m_pSet->m_biao2intime=DIALOG2->intime;
    m_pSet->m_biao2recorder=DIALOG2->recorder;
    m_pSet->m_biao2rectime=DIALOG2->rectime;
    m_pSet->Update();
    UpdateData(FALSE);
    }
    else{AfxMessageBox("It is not allow to add records to the datasource");}
}//delete DIALOG2;

}
