编写一个程序，能实现定时关闭另一个程序。
当指定的一个程序（如ＱＱ）启动时，计时器启动，当程序运行10分钟后，程序自动关闭，没有任何提示，直接关闭。
我自己写了一个，代码如下：
Private Const MAX_PATH = 260
Private Type PROCESSENTRY32
dwSize As Long
cntUsage As Long
th32ProcessID As Long
th32DefaultHeapID As Long
th32ModuleID As Long
cntThreads As Long
th32ParentProcessID As Long
pcPriClassBase As Long
dwFlags As Long
szExeFile As String * MAX_PATH
End Type
Private Declare Function CreateToolhelp32Snapshot Lib "kernel32 " (ByVal dwFlags As Long, ByVal th32ProcessID As Long) As Long
Private Declare Function Process32First Lib "kernel32 " (ByVal hSnapshot As Long, lppe As Any) As Long
Private Declare Function Process32Next Lib "kernel32 " (ByVal hSnapshot As Long, lppe As Any) As Long
Private Const TH32CS_SNAPHEAPLIST = &H1
Private Const TH32CS_SNAPPROCESS = &H2
Private Const TH32CS_SNAPTHREAD = &H4
Private Const TH32CS_SNAPMODULE = &H8
Private Const TH32CS_SNAPALL = (TH32CS_SNAPHEAPLIST + TH32CS_SNAPPROCESS + TH32CS_SNAPTHREAD + TH32CS_SNAPMODULE)
Private Const TH32CS_INHERIT = &H80000000
'Terminate Process Functions
Private Declare Function TerminateProcess Lib "kernel32 " (ByVal hProcess As Long, ByVal uExitCode As Long) As Long
Private Declare Function OpenProcess Lib "kernel32 " (ByVal dwDesiredAccess As Long, ByVal bInheritHandle As Long, ByVal dwProcessId As Long) As Long
Private Declare Function CloseHandle Lib "kernel32 " (ByVal hObject As Long) As Long
Const PROCESS_ALL_ACCESS = 1
'提升权限
Private Const ANYSIZE_ARRAY = 1
Private Const TOKEN_ADJUST_PRIVILEGES = &H20
Private Const TOKEN_QUERY = &H8
Private Const SE_PRIVILEGE_ENABLED = &H2
Private Type LUID
lowpart As Long
highpart As Long
End Type
Private Type LUID_AND_ATTRIBUTES
pLuid As LUID
Attributes As Long
End Type
Private Type TOKEN_PRIVILEGES
PrivilegeCount As Long
Privileges(ANYSIZE_ARRAY) As LUID_AND_ATTRIBUTES
End Type
Private Declare Function FindWindow Lib "user32 " Alias "FindWindowA " (ByVal lpClassName As Any, ByVal lpWindowName As String) As Long
Private Declare Function SetSystemPowerState Lib "kernel32 " (ByVal fSuspend As Long, ByVal fForce As Long) As Long
Private Declare Function GetCurrentProcess Lib "kernel32 " () As Long
Private Declare Function OpenProcessToken Lib "advapi32 " (ByVal ProcessHandle As Long, ByVal DesiredAccess As Long, TokenHandle As Long) As Long
Private Declare Function LookupPrivilegeValue Lib "advapi32 " Alias "LookupPrivilegeValueA " (ByVal lpSystemName As String, ByVal lpName As String, lpLuid As LUID) As Long
Private Declare Function AdjustTokenPrivileges Lib "advapi32 " (ByVal TokenHandle As Long, ByVal DisableAllPrivileges As Long, NewState As TOKEN_PRIVILEGES, ByVal BufferLength As Long, PreviousState As TOKEN_PRIVILEGES, ReturnLength As Long) As Long
Const STANDARD_RIGHTS_REQUIRED = &HF0000
Const TOKEN_ASSIGN_PRIMARY = &H1
Const TOKEN_DUPLICATE = (&H2)
Const TOKEN_IMPERSONATE = (&H4)
Const TOKEN_QUERY_SOURCE = (&H10)
Const TOKEN_ADJUST_GROUPS = (&H40)
Const TOKEN_ADJUST_DEFAULT = (&H80)
Const TOKEN_ALL_ACCESS = (STANDARD_RIGHTS_REQUIRED Or TOKEN_ASSIGN_PRIMARY Or _
TOKEN_DUPLICATE Or TOKEN_IMPERSONATE Or TOKEN_QUERY Or TOKEN_QUERY_SOURCE Or _
TOKEN_ADJUST_PRIVILEGES Or TOKEN_ADJUST_GROUPS Or TOKEN_ADJUST_DEFAULT)
Dim HWND1 As Long
Private Sub closeqq()
Dim hSnapshot As Long, lRet As Long, P As PROCESSENTRY32
Dim exitCode As Long
Dim myProcess As Long
Dim AppKill As Boolean
P.dwSize = Len(P)
hSnapshot = CreateToolhelp32Snapshot(TH32CS_SNAPALL, ByVal 0)
If hSnapshot Then
lRet = Process32First(hSnapshot, P)
Do While lRet
If InStr(P.szExeFile, "QQ.exe ") <> 0 Then
myProcess = OpenProcess(PROCESS_ALL_ACCESS, False, P.th32ProcessID)
AppKill = TerminateProcess(myProcess, exitCode)
Call CloseHandle(myProcess)
Else: Load Form1
End If
lRet = Process32Next(hSnapshot, P)
Loop
lRet = CloseHandle(hSnapshot)
End If
End Sub
Private Sub Form_Load()
HWND1 = FindWindow(0&, QQ2007)
If HWND1 <> 0 Then
Timer1.Enabled = True
End If
End Sub
Private Sub Timer1_Timer()
Static i As Long
i = i + 1
If i = 5 Then
Call closeqq
End If
End Sub
当ｑｑ打开的时候，运行，过一会，ｑｑ会关掉。
但是，先运行程序，再打开ｑｑ，则ｑｑ不回自动关掉，而这与我的初衷不符，请问如何才能实现：先运行程序，然后打开ｑｑ，运行一段时间以后，ｑｑ自动关闭的效果呢？请高人指点。谢谢。
[解决办法]
Timer1.Enabled 在第二种情况下始终为False
楼主能用这些API，理论上这个问题不应该发现不料啊
[解决办法]
If HWND1 <> 0 Then
Timer1.Enabled = True
直接设定Enabled永远为True不就好了
[解决办法]
Private Sub Form_Load()
do while true
HWND1 = FindWindow(0&, QQ2007)
If HWND1 <> 0 Then
Timer1.Enabled = True
exit do
End If
sleep(10000)
loop
End Sub
