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);
