利用WindowsAPI獲得系統高級功能

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:

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。
