我看到很多关于计算程序中空闲时间的帖子,但我想要做的是计算单独Windows程序的空闲时间。长话短说,我们有非常昂贵的会计软件的12个许可证。我们有大约20名员工,但不是每个人都使用该软件。我们将不时地使用所有12个许可证 - 并且公司中有一个层次结构,关于谁应该能够根据需要访问软件。
我的任务是编写一个程序,让我们开始#34;用户。我写了一个简单的程序,它将在后台运行并检查软件是否已加载。另一个程序只是通过共享网络驱动器发送命令,以告诉程序在必要时关闭。
有效。我现在被要求做的是包括软件的空闲时间。有没有办法监视外部应用程序的击键或鼠标点击?我想我基本上可以报告上次使用应用程序的时间,并从当前时间中减去空闲时间。但是,我正在努力弄清楚如何将任何密钥发送到特定应用程序?从逻辑上讲,我认为这就像一个键盘记录器(没有记录),但只有当特定应用程序处于焦点时才会这样。
有没有人有我可以探索的想法?我愿意做研究,但只是想知道是否有人知道任何API或其他技巧。

您可以在合理的循环中合并GetForgroundWindow
和GetLastInputInfo
(Win32函数)
如果目标应用程序(目标)正在运行,并且目标不是前台窗口,那么我们可以假设应用程序处于空闲状态。只记录它从前景转换到背景的时间。
如果目标是前景窗口,那么您可以使用GetLastInputInfo
来确定应用程序上次接收鼠标或键盘输入的时间。
**不幸的是MSDN现在已经关闭,所以我无法链接到文档。

所以我的设置存储了用户日志的位置。如果我发现用户打开了一个应用程序(Axys),那么我用他们的windows用户名(.usr文件)创建一个文件。在该文件中,我保存上次应用程序处于活动状态。
Dim strFileName As String = My.Settings.UserLogs & "\" & strWinUser & ".usr"
Dim strTime As String = String.Empty
lastInputInf.cbSize = Marshal.SizeOf(lastInputInf)
lastInputInf.dwTime = 0
GetLastInputInfo(lastInputInf)
Dim Caption As New System.Text.StringBuilder(256)
GetWindowText(GetForegroundWindow, Caption, Caption.Capacity)
If Caption.ToString.Contains("Axys") Then
If (CInt((Environment.TickCount - lastInputInf.dwTime) / 1000)) > 0 Then
Dim timeDbl As Double = CDbl((Environment.TickCount - lastInputInf.dwTime) / 1000)
strTime = DateTime.Now.AddSeconds(-1 * timeDbl).ToString
Else
strTime = DateTime.Now.ToString
End If
Dim objWriter As New System.IO.StreamWriter(strFileName)
objWriter.Write(strTime)
objWriter.Close()
Else
End If

不确定这是否有所帮助,但可能通过微软的UPTIME.exe获得了良好的信息。它是一个跟踪正常运行时间,靴子,蓝屏等的工具。
这里有一个vbscript可能有一些线索来获取VB.NET的这些信息

我也想知道查询Windows Management Instrumentation是否会有所帮助。
我希望这里有所帮助。祝你好运。
