VB程序后台运行

vb 窗口最小到时间边上从底部d出

1、新建立一个VB6工哗肢程，将Form1的ShowInTaskBar属性设置为False -----------------------------------------------

2、菜单：工程--添加模块 按“打开”这样就添散辩加了一个新模块，名为Module1,保存为Module1.bas -------------------

3、在Module1中写下冲芦缺如下代码： ------------------------------------------------------------------------------

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的代码全部如下：-----------------------------------------------------------------------------

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

Private Sub Form_QueryUnload(Cancel As Integer, UnloadMode As Integer)

Call Shell_NotifyIcon(NIM_DELETE, nfIconData)

End Sub

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, "实时播音专家"

'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d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

7、现在将程序保存起来运行看看系统托盘处是否增加了一个本工程的图标。单击此图标，Form1就自动d出来了

以下都可以后台（不会显示在棚辩任务栏，不会显示在任务管理器的应用程序）

一、MFC不要窗口（进程还是会有）

二、注册成windows服务（进程还是会有）（windows服务是正统的后台）

（以下任务管理器进程也看不到链握缺，反正就是找不到）

三、DLL远程注入

四、hook

五、shellcode注入到皮闷任一程序
