實現方法：(用VS.net的可視化實現）
新建一個項目(notifyicon)
把右鍵菜單（contextmenu)拖入表單中.加入菜單的子菜單項。比如“顯示”、“隱藏”等菜單項。
雙擊各菜單項為各菜單項加入單擊事件。
比如：（顯示）me.show
(隱藏）me.hide
把托盤控件拖入表單中。設置其顯示文字(.text)、圖標文件(icon)
設置托盤的右鍵菜單(contextmenu)為你剛才創建的菜單。
這樣就很方便的實現以前VB需要好多的Win API才能實現的功能。
附上該form的源代碼
Public Class notifyIcon
Inherits System.Windows.Forms.Form
#Region " Windows Form Designer generated code "
Public Sub New()
MyBase.New()
'This call is required by the Windows Form Designer.
InitializeComponent()
'Add any initialization after the InitializeComponent() call
End Sub
'Form overrides dispose to clean up the component list.
Protected Overloads Overrides Sub Dispose(ByVal disposing As Boolean)
If disposing Then
If Not (components Is Nothing) Then
components.Dispose()
End If
End If
MyBase.Dispose(disposing)
End Sub
'Required by the Windows Form Designer
Private components As System.ComponentModel.IContainer
