c# - 是否可以使用 C# 删除另一个应用程序的大小调整和关闭？

Question

我想知道是否可以使用 C# 移除关闭其他窗口的功能？

我知道您可以覆盖 Windows 的 close() 方法，但其他进程也可以这样吗？以及如何将另一个进程的窗口样式更改为 fixed___ 以使其无法调整大小？

到目前为止，我已经获得了应用程序的主窗口句柄，并且删除了所有按钮和菜单，但我仍然需要弄清楚如何使其无法关闭和调整大小。

这是我得到的:

有什么想法吗？ (:

正如我在评论中所说，这里有一些关于这个问题的更多细节:

我需要两个应用程序并排显示在显示器上。它们都不能关闭或调整大小。一个是浏览器，另一个是名为“Z-tree”的应用程序。我已经解决了 Z-tree 的问题，因为它在默认情况下运行时没有关闭按钮，也没有调整大小，您可以在命令行中指定它的大小和位置。

还有一个思路，创建一个winforms项目，设置窗口不能调整大小。然后在表单中嵌入一个 WebBrowser 控件并在表单加载中导航到您的页面:

private void Form1_Load(object sender, EventArgs e)
{
     //catch form closing event to prevent form being closed using alt-f4
     FormClosing += Form1_FormClosing;

     //remove close button from toolbar and remove window border to prevent
     //moving and resizing
     this.ControlBox = false;
     this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;

     //set position to half of the screen
     this.Left = Screen.PrimaryScreen.Bounds.Width / 2;
     this.Top = 0;
     this.Width = Screen.PrimaryScreen.Bounds.Width / 2;
     this.Height = Screen.PrimaryScreen.Bounds.Height;

     //mark the window as a top level window, reducing users ability to alt-tab away
     TopMost = true;

     webBrowser1.Navigate("www.google.com");
}

private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
     //prevent form being closed
     e.Cancel = true;
}

//the only way to close the form
void DoExit()
{    
     //remove the closing handler first or it won't close
     FormClosing -= Form1_FormClosing;
     Close();
}
