VB6如何在托盤中寫入應用程序圖標

　1、新建立一個VB6工程，將Form1的ShowInTaskBar屬性設置為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：

clearcase/" target="_blank" >cc66" width="90%" align="center" bgcolor="#dadacf" border="1">

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、現在將程序保存起來運行看看系統托盤處是否增加了一個本工程的圖標。單擊此圖標，Form1就自動彈出來了。
