1、新建立一个VB6工程，将Form1的ShowInTaskBar属性设置为False

2、菜单：工程--添加模块按“打开”这样就添加了一个新模块，名为Module1,保存为Module1.bas

3、在Module1中写下如下代码：

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事件中写下如下代码：

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

'定义鼠标移动到托盘上时显示的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事件中写入如下代码：

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

End Sub

6、在Form1的MouseMove事件中写下如下代码：

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 "请用鼠标右键点击图标!", vbInformation, "实时播音专家"

'单击左键，显示窗体

ShowWindow Me.hWnd, SW_RESTORE

'下面两句的目的是把窗口显示在窗口最顶层

'Me.Show

'Me.SetFocus

'' Case WM_RBUTTONUP

'' PopupMenu MenuTray '如果是在系统Tray图标上点右键，则弹出菜单MenuTray

'' Case WM_MOUSEMOVE
