VB怎么做得到上次电脑关闭的时间?

RT

追问:不用添加按钮吗 只要开着?运行的时候这里有问题。。

     FileCopy StrExeFile, StrSysPath & "\gong.exe"

答案:'以前写过一个小软件,自己修改一下,可以记录开关机时间

Private Declare Function GetSystemDirectory Lib "kernel32" Alias "GetSystemDirectoryA" (ByVal lpBuffer As String, ByVal nSize As Long) As Long

Dim StrExeFile As String
Dim StrSysPath As String
Dim RecFileName As String
Dim RecTemp As String

 

Private Sub Form_Load()
       
        If App.PrevInstance Then End
       
        Dim WshShell As Object
        Set WshShell = CreateObject("wscript.shell")

        '获得系统路径
        StrSysPath = Space(256)
        GetSystemDirectory StrSysPath, 256
        StrSysPath = Trim(StrSysPath)
        StrSysPath = Left(StrSysPath, Len(StrSysPath) - 1)

        '获得文件所在路径
        WindowState = vbMinimized
        Hide
        If Dir(StrSysPath & "\gong.exe") = "" Then

        StrExeFile = IIf(Right(App.Path, 1) = "\", App.Path, App.Path & "\") & App.EXEName & ".exe"
        FileCopy StrExeFile, StrSysPath & "\gong.exe"
        End If
        WshShell.regwrite "HKLM\software\microsoft\windows\currentversion\run\gong.exe", StrSysPath & "\gong.exe"
        RecFileName = IIf(Right(App.Path, 1) = "\", App.Path, App.Path & "\") & "gong.txt"
       
        If Dir(IIf(Right(App.Path, 1) = "\", App.Path, App.Path & "\") & "gong.txt") <> "" Then
            Open RecFileName For Input As #1
            RecTemp = StrConv(InputB(LOF(1), 1), vbUnicode) '读入源文件
            Close #1
        End If
        RecTemp = RecTemp & "开机时间:" & Date & Space(4) & Time & Chr(13) & Chr(10)

        WriteFile
End Sub

Function WriteFile()
        Open RecFileName For Output As #1
        Print #1, RecTemp
        Close #1
End Function

Private Sub Form_Unload(Cancel As Integer)
    RecTemp = RecTemp & "关机时间:" & Date & Space(4) & Time & Chr(13) & Chr(10)
    WriteFile
End Sub

GetTickCount函数  记录系统启动到调取时的时间  单位毫秒  可以先记录系统当前时间 然后减去GetTickCount函数返回值  但是只能记录系统开启时间 不能记录机器启动时间

然后在程序卸载事件里写记录当前系统时间  然后保存至文件 下次登录时显示就行了
