我试图在C#中隐藏Windows 7任务栏。我查看了this帖子和 this 页面,但在按照所有说明操作后,我最后在底部放了一个纯黑色条。 我最终得到了这样的任务栏类:
using System;
using System.Collections.Generic;
using System.Text;
using System.Runtime.InteropServices;
using System.Diagnostics;
public static class Taskbar
{
[DllImport("user32.dll")]
private static extern int GetWindowText(IntPtr hWnd, StringBuilder text, int count);
[DllImport("user32.dll", CharSet = CharSet.Auto)]
private static extern bool EnumThreadWindows(int threadId, EnumThreadProc pfnEnum, IntPtr lParam);
[DllImport("user32.dll", SetLastError = true)]
private static extern System.IntPtr FindWindow(string lpClassName, string lpWindowName);
[DllImport("user32.dll", SetLastError = true)]
private static extern IntPtr FindWindowEx(IntPtr parentHandle, IntPtr childAfter, string className, string windowTitle);
[DllImport("user32.dll")]
private static extern int ShowWindow(IntPtr hwnd, int nCmdShow);
[DllImport("user32.dll")]
private static extern uint GetWindowThreadProcessId(IntPtr hwnd, out int lpdwProcessId);
private const int SW_HIDE = 0;
private const int SW_SHOW = 5;
private const string VistaStartMenuCaption = "Start";
private static IntPtr vistaStartMenuWnd = IntPtr.Zero;
private delegate bool EnumThreadProc(IntPtr hwnd, IntPtr lParam);
public static void Show()
{
SetVisibility(true);
}
public static void Hide()
{
SetVisibility(false);
}
public static bool Visible
{
set { SetVisibility(value); }
}
private static void SetVisibility(bool show)
{
IntPtr taskBarWnd = FindWindow("Shell_TrayWnd", null);
IntPtr startWnd = FindWindowEx(taskBarWnd, IntPtr.Zero, "Button", "Start");
if (startWnd == IntPtr.Zero)
{
startWnd = FindWindow("Button", null);
if (startWnd == IntPtr.Zero)
{
startWnd = GetVistaStartMenuWnd(taskBarWnd);
}
}
ShowWindow(taskBarWnd, show ? SW_SHOW : SW_HIDE);
ShowWindow(startWnd, show ? SW_SHOW : SW_HIDE);
}
private static IntPtr GetVistaStartMenuWnd(IntPtr taskBarWnd)
{
int procId;
GetWindowThreadProcessId(taskBarWnd, out procId);
Process p = Process.GetProcessById(procId);
if (p != null)
{
foreach (ProcessThread t in p.Threads)
{
EnumThreadWindows(t.Id, MyEnumThreadWindowsProc, IntPtr.Zero);
}
}
return vistaStartMenuWnd;
}
private static bool MyEnumThreadWindowsProc(IntPtr hWnd, IntPtr lParam)
{
StringBuilder buffer = new StringBuilder(256);
if (GetWindowText(hWnd, buffer, buffer.Capacity) > 0)
{
Console.WriteLine(buffer);
if (buffer.ToString() == VistaStartMenuCaption)
{
vistaStartMenuWnd = hWnd;
return false;
}
}
return true;
}
}
我拍摄了问题的截图:

让我的应用全屏展示会更有意义。像这样戳任务栏的内部肯定会造成麻烦。
用户可能会因失去任务栏而感到恼火。任务栏属于用户而不是应用程序。

你试试这个吗?
FROM MSDN:
Shell32.dll的4.71版及更高版本添加了修改任务栏内容的功能。从应用程序中,您现在可以添加,删除和激活任务栏按钮。激活项目不会激活窗口;它显示在任务栏上按下的项目。
任务栏修改功能在公开ITaskbarList接口(IID_ITaskbarList)的组件对象模型(COM)对象(CLSID_TaskbarList)中实现。您必须调用ITaskbarList :: HrInit方法来初始化对象。然后,您可以使用ITaskbarList接口的方法来修改任务栏的内容。

如果您有一个WPF窗口,将其WindowStyle设置为None,并将其最大化,它将覆盖整个屏幕(覆盖TaskBar)。如果您使用Windows窗体,类似的东西也可能有用。
