从任务栏隐藏外部应用程序
我看过很多不同的论坛，但我找不到办法。 我想隐藏任务栏中的外部应用程序图标，但没有最小化应用程序。 我不知道从哪里开始，或者怎么做。 任何帮助将不胜感激。
注意隐藏外部应用程序图标，而不是我的表单图标。
您可以使用ShowWindow函数执行此操作。 这是一个小样本，它将隐藏任务栏中正在运行的“calc.exe”。

- 让它由另一个窗口拥有。 您无法执行此操作，因为所有者是在窗口创建时确定的。
- 为它提供
WS_EX_TOOLWINDOW扩展窗口样式。 你可以这样做，但它会改变窗口的外观。 - 调用
ITaskbarList::DeleteTab传递窗口句柄。 虽然这会起作用，但我相信在某些情况下，任务栏按钮会返回。
从本质上讲，你试图做的是违反规则。 如果系统不易使您篡改其他应用程序，请不要感到惊讶。
Form类提供ShowInTaskbar属性。 将其设置为false，最好在InitializeComponent之后的构造函数中，并且winform应用程序将不会显示在Windows任务栏中。
public MyForm() { InitializeComponent(); this.ShowInTaskbar = false; }
