带托盘图标的WinForms应用程序

Question

我意识到一个应用程序可以在托盘图标中最小化它自己，您也可以从中显示上下文菜单。

我遇到了一些问题：

1. 当我点击其他地方时，我无法取消上下文菜单

2. 上下文菜单不会出现在托盘图标附近（它是黑色扳手）

   

3. 当我打开上下文菜单时，通常会出现一个空白任务栏项目：

   

这是Form Resize处理程序和TrayIcon Click处理程序的代码：

Private Sub MainForm_Resize(snd As Object, e As EventArgs) Handles Me.Resize
    If WindowState = FormWindowState.Minimized Then
        Me.TrayIcon.Visible = True
        Me.ShowInTaskbar = False
        Me.Hide()
    End If
End Sub

Private Sub TrayIcon_Click(snd As Object, e As EventArgs) Handles TrayIcon.Click
    Dim castedEvent As MouseEventArgs = DirectCast(e, MouseEventArgs)
    If (castedEvent.Button = Windows.Forms.MouseButtons.Left) Then
        Me.Show()
        Me.ShowInTaskbar = True
        Me.TrayIcon.Visible = False
        Me.WindowState = FormWindowState.Normal
    Else
        TrayIconContextMenu.Show(Control.MousePosition)
    End If
End Sub
