找到this question并按照那里的说明,再加上许多链接后,我设法让我的应用程序显示为系统托盘图标,当我最小化它时,它会从任务栏中消失。< / p>
但是 - 奇怪的行为!表单打开时,系统托盘图标正常工作。但是一旦我最小化它,托盘图标就会停止响应任何类型的鼠标点击。
可能发挥作用的其他事实:表单由从主线程分离的线程启动,并以.ShowDialog()
打开。还有其他几个线程在后台运行。
任何想法出了什么问题?

将f.ShowDialog();
替换为Application.Run(f);
,其中f
是包含Form
的变量,它应该可以正常工作。当您隐藏表单时,问题是ShowDialog
返回(并且它的消息循环结束)。 Application.Run
提供了一个正确的消息循环,您的窗口在隐藏后可以正常工作,并且可以使用系统托盘图标再次显示。

不太确定您的代码是什么样的,但下面是我从其中一个应用中提取的一些代码。它用VB编写但不应该太难转换。关键是要创建一个ApplicationContext类来托管您的代码。此代码在显示表单然后重复关闭或最小化或最大化时没有问题。
Public Class NotifyApplicationContext
Inherits ApplicationContext
Private components As System.ComponentModel.IContainer
Private Notify As System.Windows.Forms.NotifyIcon
Private Menu As System.Windows.Forms.ContextMenu
Private mnuForm As System.Windows.Forms.MenuItem
Private F As Form
Public Sub New()
InitializeContext()
End Sub
Private Sub InitializeContext()
Me.components = New System.ComponentModel.Container
Me.Notify = New System.Windows.Forms.NotifyIcon(Me.components)
SetupContextMenu()
Notify.ContextMenu = Me.Menu
Notify.Icon = New Icon("YourApplicationIcon", 16, 16)
Notify.Text = "Your Application Text"
Notify.Visible = True
F = New Form
F.Show()
End Sub
Protected Overrides Sub Dispose(ByVal disposing As Boolean)
MyBase.Dispose(disposing)
End Sub
Protected Overrides Sub ExitThreadCore()
MyBase.ExitThreadCore()
End Sub
Private Sub SetupContextMenu()
Me.Menu = New System.Windows.Forms.ContextMenu
Me.mnuForm = New System.Windows.Forms.MenuItem
Me.Menu.MenuItems.Add(mnuForm)
mnuForm.Index = 7
mnuForm.Text = "FormText"
AddHandler mnuForm.Click, AddressOf Me.mnuTemp_Click
End Sub
Private Sub mnuForm_Click(ByVal sender As Object, ByVal e As System.EventArgs)
If F IsNot Nothing Then
If F.Visible = True Then
F.Close()
F.Dispose()
F = Nothing
End If
Else
F = New Form
F.Show()
End If
Notify.Text = "Change Application Text Here"
End Sub

Application.Run(N)
