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

　　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
