1、新建立一個VB6工程，將Form1的ShowInTaskBar屬性設置為False

　　2、菜單：工程--添加模塊 按“打開”這樣就添加了一個新模塊，名為Module1,保存為Module1.bas

　　3、在Module1中寫下如下代碼：

　　Option Explicit

　　Public Const MAX_TOOLTIP As Integer = 64
　　Public Const NIF_ICON = &H2
　　Public Const NIF_MESSAGE = &H1
　　Public Const NIF_TIP = &H4
　　Public Const NIM_ADD = &H0
　　Public Const NIM_DELETE = &H2
　　Public Const WM_MOUSEMOVE = &H200
　　Public Const WM_LBUTTONDOWN = &H201
　　Public Const WM_LBUTTONUP = &H202
　　Public Const WM_LBUTTONDBLCLK = &H203
　　Public Const WM_RBUTTONDOWN = &H204
　　Public Const WM_RBUTTONUP = &H205
　　Public Const WM_RBUTTONDBLCLK = &H206

　　Public Const SW_RESTORE = 9
　　Public Const SW_HIDE = 0

　　Public nfIconData As NOTIFYICONDATA


　　Public Type NOTIFYICONDATA
　　cbSize As Long
　　hWnd As Long
　　uID As Long
　　uFlags As Long
　　uCallbackMessage As Long
　　hIcon As Long
　　szTip As String * MAX_TOOLTIP
　　End Type

　　Public Declare Function ShowWindow Lib "user32" (ByVal hWnd As Long, ByVal nCmdShow As Long) As Long
　　Public Declare Function Shell_NotifyIcon Lib "shell32.dll" Alias "Shell_NotifyIconA" (ByVal dwMessage As Long, lpData As NOTIFYICONDATA) As Long

　　4、在Form1的Load事件中寫下如下代碼：

　　Private Sub Form_Load()

　　'以下把程序放入System Tray====================================System Tray Begin
　　With nfIconData
　　.hWnd = Me.hWnd
　　.uID = Me.Icon
　　.uFlags = NIF_ICON Or NIF_MESSAGE Or NIF_TIP
　　.uCallbackMessage = WM_MOUSEMOVE
　　.hIcon = Me.Icon.Handle
　　'定義鼠標移動到托盤上時顯示的Tip
　　.szTip = App.Title + "(版本 " & App.Major & "." & App.Minor & "." & App.Revision & ")" & vbNullChar
　　.cbSize = Len(nfIconData)
　　End With
　　Call Shell_NotifyIcon(NIM_ADD, nfIconData)
　　'=============================================================System Tray End
　　Me.Hide
　　End Sub

　　5、在Form1的QueryUnload事件中寫入如下代碼：

　　Private Sub Form_QueryUnload(Cancel As Integer, UnloadMode As Integer)
　　Call Shell_NotifyIcon(NIM_DELETE, nfIconData)
　　End Sub
　　

　　6、在Form1的MouseMove事件中寫下如下代碼：

　　Private Sub Form_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
　　Dim lMsg As Single
　　lMsg = X / Screen.TwipsPerPixelX
　　Select Case lMsg
　　Case WM_LBUTTONUP
　　'MsgBox "請用鼠標右鍵點擊圖標!", vbInformation, "實時播音專家"
　　'單擊左鍵，顯示窗體
　　ShowWindow Me.hWnd, SW_RESTORE
　　'下面兩句的目的是把窗口顯示在窗口最頂層
　　'Me.Show
　　'Me.SetFocus
　　'' Case WM_RBUTTONUP
　　'' PopupMenu MenuTray '如果是在系統Tray圖標上點右鍵，則彈出菜單MenuTray
　　'' Case WM_MOUSEMOVE
　　'' Case WM_LBUTTONDOWN
　　'' Case WM_LBUTTONDBLCLK
　　'' Case WM_RBUTTONDOWN
　　'' Case WM_RBUTTONDBLCLK
　　'' Case Else
　　End Select
　　End Sub

　　7、現在將程序保存起來運行看看系統托盤處是否增加了一個本工程的圖標。單擊此圖標，Form1就自動彈出來了。
