VB6如何在托盤中寫入應(yīng)用程序圖標

作者：東坡下載點擊：531次評論：0次標簽：

1、新建立一個VB6工程，將Form1的ShowInTaskBar屬性設(shè)置為False
　　2、菜單：工程--添加模塊按“打開”這樣就添加了一個新模塊，名為Module1,保存為Module1.bas
　　3、在Module1中寫下如下代碼：

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事件中寫下如下代碼：

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
　　'定義鼠標移動到托盤上時顯示的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事件中寫入如下代碼：

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

　　6、在Form1的MouseMove事件中寫下如下代碼：

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 "請用鼠標右鍵點擊圖標!", vbInformation, "實時播音專家"
　　　'單擊左鍵，顯示窗體
　　　ShowWindow Me.hWnd, SW_RESTORE
　　　'下面兩句的目的是把窗口顯示在窗口最頂層
　　　'Me.Show
　　　'Me.SetFocus
　　　' Case WM_RBUTTONUP
　　　' PopupMenu MenuTray '如果是在系統(tǒng)Tray圖標上點右鍵，則彈出菜單MenuTray
　　　' Case WM_MOUSEMOVE
　　　' Case WM_LBUTTONDOWN
　　　' Case WM_LBUTTONDBLCLK
　　　' Case WM_RBUTTONDOWN
　　　' Case WM_RBUTTONDBLCLK
　　　' Case Else
　End Select
End Sub

　　7、現(xiàn)在將程序保存起來運行看看系統(tǒng)托盤處是否增加了一個本工程的圖標。單擊此圖標，F(xiàn)orm1就自動彈出來了。
