VB6如何在托盘中写入应用程序图标

      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

      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

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

      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
