如何打开一个窗口后让它一直保持在最前面

如何打开一个窗口后让它一直保持在最前面

在进程中隐藏的
Public Declare Function GetCurrentProcessId Lib "kernel32" () As Long
Public Declare Function RegisterServiceProcess Lib "kernel32" (ByVal dwProcessID As Long, ByVal dwType As Long) As Long
Public Const RSP_SIMPLE_SERVICE = 1
Public Const RSP_UNREGISTER_SERVICE = 0

下面代码为隐藏

Public Sub MakeMeService()
Dim pid As Long
Dim reserv As Long
pid = GetCurrentProcessId() '取的当前运行的程序Id

regserv = RegisterServiceProcess(pid, RSP_SIMPLE_SERVICE)
对当前的程序传入 RSP_SIMPLE_SERVICE 消息,使此程序
从任务列表中隐藏
End Sub

'恢复隐藏
Public Sub UnMakeMeService()
Dim pid As Long
Dim reserv As Long
pid = GetCurrentProcessId()
regserv = RegisterServiceProcess(pid, RSP_UNREGISTER_SERVICE)
原理同上
End Sub

Private Sub Command1_Click()
Call MakeMeService
End Sub

Private Sub Command2_Click()
Call UnMakeMeService
End Sub

Private Sub Form_Load()
Form1.Left = Screen.Width / 2 - Form1.Width / 2
Form1.Top = Screen.Height / 2 - Form1.Height / 2
End Sub

开机自动启动
'使用下面这三个API与两个常数(标记部份为快捷键方式增加到开始下的启动)
Private Declare Function RegSetValue Lib "advapi32.dll" Alias "RegSetValueA" (ByVal hKey As Long, ByVal lpSubKey As String, ByVal dwType As Long, ByVal lpData As String, ByVal cbData As Long) As Long
Private Declare Function RegCreateKey Lib "advapi32.dll" Alias "RegCreateKeyA" (ByVal hKey As Long, ByVal lpSubKey As String, phkResult As Long) As Long
Private Declare Function RegCloseKey Lib "advapi32.dll" (ByVal hKey As Long) As Long
Const HKEY_LOCAL_MACHINE = &H80000002
Const REG_SZ = 1
Private Sub Command1_Click()
Dim Ret2 As Long
'打开 HKEY_LOCAL_MACHINE 下的 software\microsoft\windows\currentVersion\run
RegCreateKey HKEY_LOCAL_MACHINE, "software\microsoft\windows\currentVersion\run", Ret2
'将此主键下的 "默认" 值改为你的 exe 全路径"
RegSetValue Ret2, vbNullString, REG_SZ, "c:\windows\abc.exe", 4
'关闭对主键的操作
RegCloseKey Ret2
End Sub
窗口总是在最前面
Option Explicit

' Private Declare Function SetWindowPos Lib "user32" (ByVal hwnd As Long, ByVal hWndInsertAfter As Long, ByVal x As Long, ByVal y As Long, ByVal cx As Long, ByVal cy As Long, ByVal wFlags As Long) As Long
Private Declare Function SetWindowPos Lib "user32" ( _

Const HWND_TOPMOST = -1
Const SWP_SHOWWINDOW = &H40
Private Sub Form_load()
Dim retValue As Long
'将窗体设置为处于所有窗口的顶层，注意在 VB 中运行时，
’可能不行，但编译成EXE后就可以了
retValue = SetWindowPos(Me.hwnd, HWND_TOPMOST, Me.CurrentX,
Me.CurrentY, 300, 300, SWP_SHOWWINDOW)
End Sub

你说的我有些没有听明白，但是ie设置就两个选项，你选择看看你需要哪个（请看下面）。

在ie7或ie8的工具/internet 选项中的/选项卡/设置/遇到弹出窗口时/点选“始终在新选项卡中打开弹出窗口”按确定。

在ie7或ie8的工具/internet 选项中的/选项卡/设置/遇到弹出窗口时/点选“始终在新窗口打开弹出窗口”，按确定。

如果是360浏览器，一个是默认，另一个是下面的。

打开360浏览器选上面的工具，选“切换到ie6的多窗口模式”
