使.NET應用程序成爲唯一可運行的程序？

使Windows .NET應用程序成爲唯一可以在計算機上使用的程序的最佳方式是什麼？ 我遇到了定時器或事件來將窗口切換回窗口，使用匹配的文本和一些api32調用將窗體設置爲最頂層。使.NET應用程序成爲唯一可運行的程序？

是否有可能使窗口鎖定屏幕的應用程序，除了屏幕上什麼都不能做什麼事情？我想阻止用戶做其他事情，只讓管理員進入桌面。

我作爲一個用戶，會發現這樣的電腦沒什麼用:-)能夠運行一個應用程序的計算機。我會感到無聊:-) –

@DarinDimitrov：我認爲這可能是某種類型的收銀軟件或類似的東西。就像一個亭子。 –

你的意思是沿[kiosk模式]（http://stackoverflow.com/questions/4617303/does-windows-7-have-a-kiosk-mode）的行？ – R0MANARMY

我發現了一個更簡單的方法來做到這一點，不使用kiosk模式或gpedits或任何事情都是這樣的。

在我的應用程序中，我用這兩個該死的簡單東西做了一個按鈕 - 沒有提出任何問題！

我用shell.cmd啓動了一次點擊應用程序appref-ms，它起到了魅力。

'The logged in user has to be administrator or the app run as administrator once. 

My.Computer.Registry.SetValue("HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\IniFileMapping\system.ini\boot", "Shell", "USR:Software\Microsoft\Windows NT\CurrentVersion\Winlogon") 

'This will change the shell to your program for THIS LOGGED IN user- after re logon bye bye exploerer shell hello custom app!    

My.Computer.Registry.SetValue("HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Winlogon", "Shell", appPath & "\shell.cmd")`

Watch my software boot as if it owns windows!

Want to understand more how it works in the full apscect?

您需要在Kiosk模式下運行您的應用程序。

外部方法

[DllImport("user32.dll")] 
private static extern int FindWindow(string cls, string wndwText); 

[DllImport("user32.dll")] 
private static extern int ShowWindow(int hwnd, int cmd); 

[DllImport("user32.dll")] 
private static extern long SHAppBarMessage(long dword, int cmd); 

[DllImport("user32.dll")] 
private static extern int RegisterHotKey(IntPtr hwnd, int id, int fsModifiers, int vk); 

[DllImport("user32.dll")] 
private static extern int UnregisterHotKey(IntPtr hwnd, int id);

常量

//constants for modifier keys 
private const int USE_ALT = 1; 
private const int USE_CTRL = 2; 
private const int USE_SHIFT = 4; 
private const int USE_WIN = 8; 

//hot key ID tracker 
short mHotKeyId = 0;

方法

private void RegisterGlobalHotKey(Keys hotkey, int modifiers) 
{ 
    try 
    { 
     // increment the hot key value - we are just identifying 
     // them with a sequential number since we have multiples 
     mHotKeyId++; 

     if (mHotKeyId > 0) 
     { 
      // register the hot key combination 
      if (RegisterHotKey(this.Handle, mHotKeyId, modifiers, Convert.ToInt16(hotkey)) == 0) 
      { 
       // tell the user which combination failed to register - 
       // this is useful to you, not an end user; the end user 
       // should never see this application run 
       MessageBox.Show("Error: " + mHotKeyId.ToString() + " - " + 
        Marshal.GetLastWin32Error().ToString(), 
        "Hot Key Registration"); 
      } 
     } 
    } 
    catch 
    { 
     // clean up if hotkey registration failed - 
     // nothing works if it fails 
     UnregisterGlobalHotKey(); 
    } 
} 


private void UnregisterGlobalHotKey() 
{ 
    // loop through each hotkey id and 
    // disable it 
    for (int i = 0; i < mHotKeyId; i++) 
    { 
     UnregisterHotKey(this.Handle, i); 
    } 
} 

protected override void WndProc(ref Message m) 
{ 
    base.WndProc(ref m); 

    // if the message matches, 
    // disregard it 
    const int WM_HOTKEY = 0x312; 
    if (m.Msg == WM_HOTKEY) 
    { 
     // Ignore the request or each 
     // disabled hotkey combination 
    } 
}

禁用熱鍵

RegisterGlobalHotKey(Keys.F4, USE_ALT); 

// Disable CTRL+W - exit 
RegisterGlobalHotKey(Keys.W, USE_CTRL); 

// Disable CTRL+N - new window 
RegisterGlobalHotKey(Keys.N, USE_CTRL); 

// Disable CTRL+S - save 
RegisterGlobalHotKey(Keys.S, USE_CTRL); 

// Disable CTRL+A - select all 
RegisterGlobalHotKey(Keys.A, USE_CTRL); 

// Disable CTRL+C - copy 
RegisterGlobalHotKey(Keys.C, USE_CTRL); 

// Disable CTRL+X - cut 
RegisterGlobalHotKey(Keys.X, USE_CTRL); 

// Disable CTRL+V - paste 
RegisterGlobalHotKey(Keys.V, USE_CTRL); 

// Disable CTRL+B - organize favorites 
RegisterGlobalHotKey(Keys.B, USE_CTRL); 

// Disable CTRL+F - find 
RegisterGlobalHotKey(Keys.F, USE_CTRL); 

// Disable CTRL+H - view history 
RegisterGlobalHotKey(Keys.H, USE_CTRL); 

// Disable ALT+Tab - tab through open applications 
RegisterGlobalHotKey(Keys.Tab, USE_ALT);

隱藏任務欄kiosk模式

// hide the task bar - not a big deal, they can 
// still CTRL+ESC to get the start menu; for that 
// matter, CTRL+ALT+DEL also works; if you need to 
// disable that you will have to violate SAS and 
// monkey with the security policies on the machine 

ShowWindow(FindWindow("Shell_TrayWnd", null), 0);

是好 - 我想這是最好的答案，但我實際上要使用評論中提供的鏈接到PDF如何更改defautl殼程序 - 做所有的代碼不會是必要的，如果用戶想要桌面，我從我的「shell」應用程序運行explorer shell，一切都很好。感謝您的好評！ – ppumkin

如果你的目的是永久阻止這個指定的用戶，則可以通過管理該適當的組策略。

例如，在本地組策略編輯器（開始菜單→gpedit.msc），去本地計算機策略→用戶配置→管理模板→系統。你會發現兩個選項：

  • 不要運行指定的Windows應用程序
  • 只運行指定的Windows應用程序

當然，你所要做的組策略的精細化管理，以限制其他的事情對於指定的用戶，防止更改配置，重新啓動機器等。而且您還必須通過鍵盤掛鉤使應用程序阻止特殊鍵。

請記住：不僅僅依賴鉤子，全屏模式和其他防止用戶超出應用程序的東西。如果你這樣做，有一天你的應用程序會崩潰，給用戶無限制的訪問底層操作系統，文件系統等。
