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 　　　 Case WM_LBUTTONDOWN 　　　 Case WM_LBUTTONDBLCLK 　　　 Case WM_RBUTTONDOWN 　　　 Case WM_RBUTTONDBLCLK 　　　 Case Else 　End Select End Sub

　　7、现在将程序保存起来运行看看系统托盘处是否增加了一个本工程的图标。单击此图标，Form1就自动弹出来了。
