How to? WPF Window - Maximized, No Resize/Move
提问by Thieres Tembra
I'm trying to make a WPF window that opens already maximized, with no resize/move (in systemmenu, nor in border). It should be maximized all the time, except when the user minimize it.
我正在尝试制作一个已经最大化打开的 WPF 窗口，没有调整大小/移动（在系统菜单中，也没有在边框中）。它应该一直最大化，除非用户最小化它。
I tried to put WindowState="Maximized" and ResizeMode="CanMinimize", but when window opens, it covers the task bar (i don't want it).
我试图把 WindowState="Maximized" 和 ResizeMode="CanMinimize"，但是当窗口打开时，它覆盖了任务栏（我不想要它）。
I have an hook to WndProc that cancels the SC_MOVE and SC_SIZE. I also can make this control with conditions in WndProc like "if command is restore and is minimized, restore, else, block" and so on.
我有一个到 WndProc 的钩子，它取消了 SC_MOVE 和 SC_SIZE。我还可以使用 WndProc 中的条件进行此控制，例如“如果命令被还原并被最小化，还原，否则，阻止”等等。
But my point is if we have another way to make it. Thankz for read guys =)
但我的观点是我们是否有另一种方式来实现。感谢阅读伙计们 =)

It is necessary to write WindowState="Maximized" ResizeMode="NoResize"in xaml of your window:
有必要WindowState="Maximized" ResizeMode="NoResize"在您的窗口的 xaml 中写入 ：
<Window x:Class="Miscellaneous.EditForm"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Edit Form" WindowState="Maximized" ResizeMode="NoResize"></Window>

public Window1()
{
InitializeComponent();
this.SourceInitialized += Window1_SourceInitialized;
}
private void Window1_SourceInitialized(object sender, EventArgs e)
{
WindowInteropHelper helper = new WindowInteropHelper(this);
HwndSource source = HwndSource.FromHwnd(helper.Handle);
source.AddHook(WndProc);
}
const int WM_SYSCOMMAND = 0x0112;
const int SC_MOVE = 0xF010;
private IntPtr WndProc(IntPtr hwnd, int msg, IntPtr wParam, IntPtr lParam, ref bool handled)
{
switch (msg)
{
case WM_SYSCOMMAND:
int command = wParam.ToInt32() & 0xfff0;
if (command == SC_MOVE)
{
handled = true;
}
break;
default:
break;
}
return IntPtr.Zero;
}

WindowState="Maximized"
ResizeMode="NoResize"
WindowStyle="None"
WindowStyle="None" do what you want, but... you lose the window title, close button and have other problems.
WindowStyle="None" 做你想做的事，但是......你失去了窗口标题、关闭按钮和其他问题。

As Tergiver pointed out, this is not possible in a purely WPF manner. You have to use P/Invoke. As for why the window covers the taskbar when it opens, I think you are messing up some required calls by canceling SC_MOVE and SC_SIZE. Maybe you should cancel those calls after the window has been loaded.
正如 Tergiver 指出的那样，这在纯粹的 WPF 方式中是不可能的。您必须使用 P/Invoke。至于为什么窗口打开时会覆盖任务栏，我认为您通过取消SC_MOVE和SC_SIZE来搞乱一些必需的调用。也许您应该在窗口加载后取消这些调用。
