VB程序 托盘

如何让VB程序运行后有托盘？？

Answer 1

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, "VB系统托盘制作！"
'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
