Question

VC中TAB控件在对话框上不显示标签 而是一个白板？

BOOL CDlgScoreAnalysis::OnInitDialog()
{
CDialog::OnInitDialog();

// TODO: Add extra initialization here
TCITEM tcItem;
tcItem.mask = TCIF_TEXT;
tcItem.pszText = _T("成绩列表");
m_tab.InsertItem(0,&tcItem);

tcItem.pszText = _T("列表统计");
m_tab.InsertItem(1,&tcItem);

m_page1.Create(IDD_DLG_SCORELIST,&m_tab);
m_page2.Create(IDD_DLG_SCORESTATISTICS,&m_tab);
// m_page1.Create(IDD_DLG_SCORELIST,GetDlgItem(IDC_TAB));
// m_page2.Create(IDD_DLG_SCORESTATISTICS,GetDlgItem(IDC_TAB));

//设定在Tab内显示范围
CRect rect;
m_tab.GetClientRect(rect);
rect.top+=20;
rect.bottom-=8;
rect.left+=8;
rect.right-=8;

m_page1.MoveWindow(&rect);
m_page2.MoveWindow(&rect);

//用数组吧对话框对象指针保存起来
// pDialog[0]=&m_page1;
// pDialog[1]=&m_page2;

// //显示初始页面
// pDialog[0]->ShowWindow(SW_SHOW);
// pDialog[1]->ShowWindow(SW_HIDE);

m_page1.ShowWindow(SW_SHOW);
m_page2.ShowWindow(SW_HIDE);
m_tab.SetCurSel(0);

//保存当前选择
m_CurSelTab=0;

return TRUE; // return TRUE unless you set the focus to a control
// EXCEPTION: OCX Property Pages should return FALSE
}
void CDlgScoreAnalysis::OnSelchangeTab(NMHDR* pNMHDR, LRESULT* pResult)
{
// TODO: Add your control notification handler code here
CString str;
m_CurSelTab=m_tab.GetCurSel();
switch(m_CurSelTab)
{
case 0:
m_page1.UpdateData(TRUE);
m_page1.ShowWindow(TRUE);
m_page2.ShowWindow(FALSE);

case 1:
m_page2.UpdateData(TRUE);
m_page1.ShowWindow(FALSE);
m_page2.ShowWindow(TRUE);
}

// pDialog[m_CurSelTab]->ShowWindow(SW_HIDE);
// m_CurSelTab=m_tab.GetCurSel();
// pDialog[m_CurSelTab]->ShowWindow(SW_SHOW);

*pResult = 0;
}
