UAC后TabControl显示异常 [英] TabControl shows abnormal after UAC

问题描述

大家好：



我用正常方式在MFC中创建Tab，

我发现有关Tab控件的问题最近。

在Win7中用用户帐户控制（UAC）打开另一个应用程序后，Tab变得异常。

喜欢这张图片：http://i.imgur.com/xntxhDV.jpg [ ^ ]

当问题发生时，它仍然可以使用，如果我在Tab中选择了另一个页面，它会正常！

我认为这是因为UAC之后显示的切片不正常...

希望有人可以帮我一把，

谢谢!!



我粘贴了下面的选项卡代码：
OnInitDialog（）中的
：

Hi all:

I use the normal way to create the Tab in MFC,
and I find a problem about Tab control, recently.
The Tab is abnormal after I opened the another application with User Account Control(UAC) in Win7.
Like this picture: http://i.imgur.com/xntxhDV.jpg[^]
When the problem happened, it still can use, and if I selected the another page in Tab, it's gonna normal!
I think it happened because the slices of display is not normal after the UAC...
Hope someone can give me a hand,
thank you!!

I pasted my Tab code below:
in OnInitDialog( ):

TCITEM tc1,tc2;
tc1.mask = TCIF_TEXT;
tc1.pszText = _T("page1");
tc2.mask = TCIF_TEXT;
tc2.pszText = _T("page2");

m_tab.InsertItem(0, &tc1);
m_tab.InsertItem(1, &tc2);

CRect rec;
m_tab.GetClientRect(&rec);

    //I don't show the edge about Tab
rec.bottom += 0;
rec.left -= 0;
rec.top += 20;
rec.right -= 0;

m_page1.Create(IDD_DIALOG1, GetDlgItem(IDC_TAB1));
m_page2.Create(IDD_DIALOG2, GetDlgItem(IDC_TAB1));
m_page1.MoveWindow(&rec);
m_page2.MoveWindow(&rec);
m_page1.ShowWindow(SW_SHOW);
m_page2.ShowWindow(SW_HIDE);

void Ctab3Dlg::OnSelchangeTab(NMHDR* pNMHDR, LRESULT* pResult) 
{  
   switch (m_tab.GetCurSel()) 
    { 
      case 0: 
            m_page1.ShowWindow(SW_SHOW); 
            m_page2.ShowWindow(SW_HIDE ); 
            break; 
       case 1: 
            m_page1.ShowWindow(SW_HIDE); 
            m_page2.ShowWindow(SW_SHOW); 
            break; 
      default: 
            break; 
    }
	*pResult = 0; 
}

推荐答案

我们已经做了一些互动实验（请参阅问题的评论），试图更准确地描述症状，并最终找到问题。正如我所怀疑的那样，代码中的一些东西，我从代码示例中看不到，阻止了所有图形的正确重新渲染。对于下一步，尝试尝试两个函数： CWnd :: Invalidate （首先）或 CWnd :: RedrawWindow ：

特别是，要在处理程序中使其无效或重绘消息 WM_ACTIVATE ：

We have done some interactive experiments (please see comments to the question) in attempts to more accurately characterize the symptom and eventually locate the problem. As I suspected, something in the code, which I cannot see from the code sample, prevents proper re-rendering of all the graphics. For the next step, try to experiment with two functions: CWnd::Invalidate (first of all) or CWnd::RedrawWindow:

http://msdn.microsoft.com/en-us/library/0fdz8ey6.aspx[^].

See also: http://msdn.microsoft.com/en-us/library/btaacw58.aspx[^].

In particular, the to invalidate or redraw it in a handler of the message WM_ACTIVATE:
