使 Windows .NET 应用程序成为唯一可以在计算机上使用的程序的最佳方法是什么？我遇到了计时器或事件来将窗口切换回具有匹配文本的窗口和一些 api32 调用以使表单成为最重要的。
是否可以制作像 Windows 锁屏这样的应用程序，除了屏幕上的内容之外什么都做不了？我想阻止用户做其他事情，只让管理员进入桌面。

您需要在信息亭模式下运行您的应用程序。
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);
常数
//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);

如果您的意图是永久阻止指定用户，您可以通过适当的组策略进行管理。
例如，在本地组策略编辑器（开始菜单→ gpedit.msc）中，转到本地计算机策略→用户配置→管理模板→系统。你会发现两个选项：
- 不要运行指定的 Windows 应用程序
- 仅运行指定的 Windows 应用程序
当然，您必须对组策略进行精细管理，以限制指定用户的其他操作，防止更改配置、重新启动机器等，您还必须让您的应用程序通过键盘挂钩阻止特殊键。
记住：不要仅仅依靠钩子、全屏模式和其他东西来阻止用户离开你的应用程序。如果你这样做了，有一天你的应用程序会崩溃，让用户可以无限制地访问底层操作系统、文件系统等。

我找到了一种更简单的方法来做到这一点，而不是使用信息亭模式或 gpedits 或任何类似的东西。
在我的应用程序中，我用这两个该死的简单东西制作了一个按钮 - 没有问题！
我使用 shell.cmd 启动了一次单击应用程序 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")`
