本文告诉大家如何隐藏系统窗口菜单
系统的窗口菜单请看下图
通过在消息里面钩调一些消息的方式,此方法由 黄滨滨 大佬提供
private IntPtr Hook(IntPtr hwnd, int msg, IntPtr wparam, IntPtr lparam, ref bool handled) { if (msg == 0x112) { var param = wparam.ToInt32(); if (param is 0xf093 // 单击打开菜单 || param is 0xf100)//键盘打开菜单 { handled = true; } } else if (msg == 0xa4) { var param = wparam.ToInt32(); if (param == 0x02 // 非图片客户区 || param is 0x03) { handled = true; } } return IntPtr.Zero; }
第二个方法是通过设置样式
public MainWindow() { InitializeComponent(); SourceInitialized += OnSourceInitialized; } private void OnSourceInitialized(object sender, EventArgs e) { var windowInteropHelper = new WindowInteropHelper(this); var hwnd = windowInteropHelper.Handle; var windowLong = GetWindowLong(hwnd, GWL_STYLE); windowLong &= ~WS_SYSMENU; SetWindowLongPtr(hwnd, GWL_STYLE, new IntPtr(windowLong)); } public const int WS_SYSMENU = 0x00080000; [DllImport("user32.dll", SetLastError = true)] public static extern int GetWindowLong(IntPtr hWnd, int nIndex); public const int GWL_STYLE = -16; public static IntPtr SetWindowLongPtr(IntPtr hWnd, int nIndex, IntPtr dwNewLong) { if (Environment.Is64BitProcess) { return SetWindowLongPtr64(hWnd, nIndex, dwNewLong); } return new IntPtr(SetWindowLong32(hWnd, nIndex, dwNewLong.ToInt32())); } [DllImport("user32.dll", EntryPoint = "SetWindowLong")] private static extern int SetWindowLong32(IntPtr hWnd, int nIndex, int dwNewLong); [DllImport("user32.dll", EntryPoint = "SetWindowLongPtr")] private static extern IntPtr SetWindowLongPtr64(IntPtr hWnd, int nIndex, IntPtr dwNewLong);
