[英]Hide and Show taskbar on windows 10
I have a wpf application which is in maximized state always without showing taskbar. 我有一个WPF应用程序,始终处于最大化状态,而不会显示任务栏。 Here is the code for Hiding and showing taskbar.
这是隐藏和显示任务栏的代码。
[DllImport("user32.dll")]
private static extern int FindWindow(string className, string windowText);
[DllImport("user32.dll")]
private static extern int ShowWindow(int hwnd, int command);
private const int SW_HIDE = 0;
private const int SW_SHOW = 1;
static int hwnd = FindWindow("Shell_TrayWnd", "");
public static new void Hide()
{
ShowWindow(hwnd, SW_HIDE);
}
public static new void Show()
{
ShowWindow(hwnd, SW_SHOW);
}
This is working fine on windows 7. But when application runs on Windows 10.. taskbar didnt show up again by calling show(). 这在Windows 7上正常运行。但是,当应用程序在Windows 10上运行时,任务栏没有通过调用show()再次显示。
Here is the part where I am calling show() 这是我正在调用show()的部分
#region Show Desktop
private void Desktop_MouseUp(object sender, MouseButtonEventArgs e)
{
if (e.ChangedButton == MouseButton.Left )
{
this.WindowState = System.Windows.WindowState.Minimized;
Shell32.Shell objShel = new Shell32.Shell();
objShel.MinimizeAll();
Show();
}
}
#endregion
This works on the main display and is taken from here and converted to c#. 这在主显示屏上起作用,并从此处获取并转换为c#。
public static class Taskbar
{
[DllImport("user32.dll", SetLastError = true, CharSet = CharSet.Auto)]
private static extern IntPtr FindWindow(
string lpClassName,
string lpWindowName);
[DllImport("user32.dll", SetLastError = true)]
private static extern int SetWindowPos(
IntPtr hWnd,
IntPtr hWndInsertAfter,
int x,
int y,
int cx,
int cy,
uint uFlags
);
[Flags]
private enum SetWindowPosFlags : uint
{
HideWindow = 128,
ShowWindow = 64
}
public static void Show()
{
var window = FindWindow("Shell_traywnd", "");
SetWindowPos(window, IntPtr.Zero, 0, 0, 0, 0, (uint) SetWindowPosFlags.ShowWindow);
}
public static void Hide()
{
var window = FindWindow("Shell_traywnd", "");
SetWindowPos(window, IntPtr.Zero, 0, 0, 0, 0, (uint)SetWindowPosFlags.HideWindow);
}
}
