高手进~如何将窗体真正的全屏！！！ 不显示任务栏

Question

topmost设为true；
windowstate设为maximized;
然后formborderstyle设为none
这些我都做了 任务栏还是在 怎么办啊 ~~~~

Answer 1

            ShowIcon = false;
            ShowInTaskbar = false;

Answer 2

不使用Windowstate   this.TopMost = true;
            this.Location = new Point(0, 0);
            this.Size = new Size(Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height);

Answer 3

可以调用系统api但是我不会 请问有高人吗？谢谢了

Answer 4

this.FormBorderStyle = FormBorderStyle.None;
this.WindowState = FormWindowState.Maximized;要注意代码的顺序

Answer 5

要先执行this.FormBorderStyle = FormBorderStyle.None; 再最大化。

    using System.Runtime.InteropServices;    public class TaskBar 
    { 
        [DllImport("user32.dll", EntryPoint = "FindWindowA")] 
        private static extern IntPtr FindWindowA(string lp1, string lp2); 
        [DllImport("user32.dll", EntryPoint = "ShowWindow")] 
        private static extern IntPtr ShowWindow(IntPtr hWnd, int _value); 
        [DllImport("shell32.dll")] 
        private static extern int SHAppBarMessage(int dwMessage, ref APPBARDATA pData);         const int ABS_AUTOHIDE = 1; 
        const int ABS_ONTOP = 2; 
        const int ABM_SETSTATE = 10;         static TaskBar() 
        { 
        }         //显示任务栏 
        public static void Show() 
        { 
            IntPtr hTray = FindWindowA("Shell_TrayWnd", string.Empty); 
            ShowWindow(hTray, 5); 
        }         //隐藏任务栏 
        public static void Hide() 
        { 
            IntPtr hTray = FindWindowA("Shell_TrayWnd", string.Empty); 
            ShowWindow(hTray, 0); 
        }         //设置自动隐藏 
        public static bool AutoHide 
        { 
            set 
            { 
                APPBARDATA abd = new APPBARDATA(); 
                abd.hwnd = FindWindowA("Shell_TrayWnd", string.Empty); 
                if (value) 
                { 
                    abd.lParam = ABS_AUTOHIDE | ABS_ONTOP; 
                    SHAppBarMessage(ABM_SETSTATE, ref abd); 
                } 
                else 
                { 
                    abd.lParam = ABS_ONTOP; 
                    SHAppBarMessage(ABM_SETSTATE, ref abd); 
                } 
            } 
        }         struct APPBARDATA 
        { 
            public int cbSize; 
            public IntPtr hwnd; 
            public int uCallbackMessage; 
            public int uEdge; 
            public RECT rc; 
            public int lParam; 
        } 
        struct RECT 
        { 
            public int Left; 
            public int Top; 
            public int Right; 
            public int Bottom; 
        } 
    }上面是我写的一个控制任务栏的类。如果你想强行隐藏任务栏，可以调用TaskBar.Hide()方法强行隐藏，需要时再调用TaskBar.Show()显示。

        public frmSearchMain()
        {
            InitializeComponent();            this.FormBorderStyle = FormBorderStyle.None;
            this.WindowState = FormWindowState.Maximized; 
        }

Answer 10

 this.TopMost = true; 
            this.Location = new Point(0, 0); 
            this.Size = new Size(Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height);
放到Load事件里不行吗?

给刚刚的任务栏控制类加了个TopMost属性。只要设置任务栏的TopMost为false，任何窗口都不用设置this.FormBorderStyle = FormBorderStyle.None;就可以覆盖任务栏了。需要时，再设置回来。
TaskBar.TopMost = false;

Answer 12

这位兄台，我是试过的。
this.FormBorderStyle = FormBorderStyle.None; 
this.WindowState = FormWindowState.Maximized; 
这两句在我本机测试没有任何问题。

Answer 13

对了 那个写API的 麻烦了 但是 那个TaskBar.TopMost = false; 貌似点不到

Answer 17

this.TopMost = true;
this.FormBorderStyle = FormBorderStyle.None;
this.WindowState = FormWindowState.Maximized;经测试OK

Answer 18

this.FormBorderStyle = FormBorderStyle.None; 
this.WindowState = FormWindowState.Maximized; 这个方法可行的，我也试过
