使.NET应用程序成为唯一可以运行的程序？

Question

使Windows .NET应用程序成为可以在计算机上使用的唯一程序的最佳方法是什么？我遇到了计时器或事件,将窗口切换回具有匹配文本的窗口和一些api32调用以使表单最顶层.

是否可以制作一个类似于Windows锁定屏幕的应用程序,除了屏幕上的内容之外什么也做不了？我想阻止用户做其他事情,只让管理员进入桌面.

您需要以kiosk模式运行应用程序.

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
    }
}

禁用热键

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);

隐藏任务栏

// 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);

Answer 2

我找到了一种更简单的方法来做到这一点，不使用 kiosk 模式或 gpedits 或任何类似的东西。

在我的应用程序中，我用这两个非常简单的东西制作了一个按钮 - 没有问题！

我使用 shell.cmd 启动一个单击一次应用程序 appref-ms，它很有魅力。

'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")`

观看我的软件启动，就像它拥有 Windows 一样！
