VB6如何在托盤中寫入應(yīng)用程序圖標(biāo)

作者:東坡下載  來源:uzzf  發(fā)布時(shí)間:2010-10-14 14:13:14  點(diǎn)擊:

      1、新建立一個(gè)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(gè)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(biāo)移動(dòng)到托盤上時(shí)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(biāo)右鍵點(diǎn)擊圖標(biāo)!", vbInformation, "實(shí)時(shí)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(biāo)上點(diǎn)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(yùn)行看看系統(tǒng)托盤處是否增加了一個(gè)本工程的圖標(biāo)。單擊此圖標(biāo),F(xiàn)orm1就自動(dòng)彈出來了。
