WPF中的非最小化应用程序使用C＃ [英] Non Minimizable Application in WPF usign C#

问题描述

大家好，



有没有办法阻止我的应用程序最小化到系统托盘。我必须开发一个允许用户查看该应用程序的应用程序的应用程序，这意味着应用程序将始终在我的桌面上保持打开状态，因为它不应该被最小化。但他可以将该控件的顺序设置为像Windows Media Player或类似任务管理器。在使用C＃的WPF中有任何选项。让我知道你的任何链接。

解决方案

你好，



App.xaml：

< Window x：Class =   WpfApplicationNonMinimizable.MainWindow 
 xmlns =   http://schemas.microsoft.com / winfx / 2006 / xaml / presentation 
 xmlns：x =   http：// schemas.microsoft.com/winfx/2006/xaml 
 Title =   MainWindow高度=   350宽度=   525 
 Topmost =  真 
 ResizeMode =   NoResize  >  
< Grid> 
 
 < /  网格  >  
 < /  窗口 >  

App.xaml.cs：

 使用系统; 
 使用 System.Runtime.InteropServices; 
 使用 System.Windows; 
 使用 System.Windows.Interop; 
 
 命名空间 WpfApplicationNonMinimizable 
 {
  public   partial   class  MainWindow：Window 
 {
  public   const   int  SW_SHOWNORMAL =  1 ; 
  public   const   int  SW_SHOWMINIMIZED =  2 ; 
 
 [DllImport（  user32.dll）] 
 [ return ：MarshalAs（UnmanagedType.Bool）] 
  public   static   extern   bool  GetWindowPlacement（ IntPtr  hWnd， ref  WINDOWPLACEMENT lpwndpl）; 
 
 [DllImport（  user32.dll）] 
  public   static   extern   bool  SetWindowPlacement（ IntPtr  hWnd，
  ref  WINDOWPLACEMENT lpwndpl ）; 
 
  public   struct  POINTAPI 
 {
  public   int  x; 
  public   int  y; 
} 
 
  public   struct  RECT 
 {
  public   int  left; 
  public   int  top; 
  public   int  right; 
  public   int  bottom; 
} 
 
  public   struct  WINDOWPLACEMENT 
 {
  public   int  length; 
  public   int 标志; 
  public   int  showCmd; 
  public  POINTAPI ptMinPosition; 
  public  POINTAPI ptMaxPosition; 
  public  RECT rcNormalPosition; 
} 
 
  public  MainWindow（）
 {
 InitializeComponent（）; 
} 
 
 受保护 覆盖  void  OnSourceInitialized（EventArgs e）
 {
  base  .OnSourceInitialized（e）; 
 
 尝试 
 {
系统。 IntPtr  app_hwnd =  new  WindowInteropHelper（ this ）。句柄; 
 WINDOWPLACEMENT wp =  new  WINDOWPLACEMENT（）; 
 GetWindowPlacement（app_hwnd， ref  wp）; 
 wp.showCmd =（wp.showCmd == SW_SHOWMINIMIZED？SW_SHOWNORMAL：wp.showCmd）; 
 SetWindowPlacement（app_hwnd， ref  wp）; 
} 
  catch  
 {
} 
} 
} 
} 

我受到以下文章的启发：

，当然还有Snoop的源代码。

Happy Coding，

使用窗口的对象< a href =http://msdn.microsoft.com/en-us/library/system.windows.window.windowstate.aspx>窗口状态属性。并尝试将其设置为最大化。

并使用ResizeMode以拒绝调整大小。



我没有使用过这个，但想到了建议。它可能有用。

Hi
设置表格属性 ResizeMode => NoResize 和 WindowStyle => ToolWindow

Hi all,

Is there is a way to block minimizing of my application to system tray. I have to develop an application that will allow the user to view the prupose of that Application, which mean the application will remain open in my desktop all time for that it should not be minimized. But he can set order of that control as like windows Media player or like Task Manager. is there is any option to this in WPF using C#. let me know any link you have.

Hi,

App.xaml:

<Window x:Class="WpfApplicationNonMinimizable.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525"
        Topmost="True" 
        ResizeMode="NoResize">
    <Grid>
        
    </Grid>
</Window>

App.xaml.cs:

using System;
using System.Runtime.InteropServices;
using System.Windows;
using System.Windows.Interop;

namespace WpfApplicationNonMinimizable
{
    public partial class MainWindow : Window
    {
        public const int SW_SHOWNORMAL = 1;
        public const int SW_SHOWMINIMIZED = 2;

        [DllImport("user32.dll")]
        [return: MarshalAs(UnmanagedType.Bool)]
        public static extern bool GetWindowPlacement(IntPtr hWnd, ref WINDOWPLACEMENT lpwndpl);

        [DllImport("user32.dll")]
        public static extern bool SetWindowPlacement(IntPtr hWnd,
                           ref WINDOWPLACEMENT lpwndpl);

        public struct POINTAPI
        {
            public int x;
            public int y;
        }

        public struct RECT
        {
            public int left;
            public int top;
            public int right;
            public int bottom;
        }

        public struct WINDOWPLACEMENT
        {
            public int length;
            public int flags;
            public int showCmd;
            public POINTAPI ptMinPosition;
            public POINTAPI ptMaxPosition;
            public RECT rcNormalPosition;
        }

        public MainWindow()
        {
            InitializeComponent();
        }

        protected override void OnSourceInitialized(EventArgs e)
        {
            base.OnSourceInitialized(e);

            try
            {
                System.IntPtr app_hwnd = new WindowInteropHelper(this).Handle;
                WINDOWPLACEMENT wp = new WINDOWPLACEMENT();
                GetWindowPlacement(app_hwnd, ref wp);
                wp.showCmd = (wp.showCmd == SW_SHOWMINIMIZED ? SW_SHOWNORMAL : wp.showCmd);                
                SetWindowPlacement(app_hwnd, ref wp);
            }
            catch
            {
            }
        }
    }
}

I was inspired by the following article:
http://www.codeproject.com/Articles/29560/Set-Window-Action-Minimize-Maximize

and of course the source code of Snoop.

Hi,

Use the window's object Window State property. And try setting it to Maximized.
And use ResizeMode so deny resizing.

I havent used this, but thought of suggesting. It might work.

Hi Set Form property ResizeMode=>NoResize and WindowStyle=>ToolWindow
