Question

我想知道是否可以用vbscript计算给定时间打开的窗口数量。我已经熟悉shell.application对象，并且可以计算Windows资源管理器实例，但是无论它是什么，我都希望对每个窗口（最小化或最大化）进行计数。我还考虑过要计算所有正在运行的任务，但是我需要以某种方式区分后台任务和前台任务才能使之正常工作。

function fnShellWindowsCountVB()
        dim objShell
        dim objShellWindows

        set objShell = CreateObject("shell.application")
        set objShellWindows = objshell.Windows

        if (not objShellWindows is nothing) then
            dim nCount
            nCount = objShellWindows.Count

            msgBox nCount
        end if

        set objShellWindows = nothing
        set objShell = nothing
end function
fnShellWindowsCountVB()

'only counts explorer.exe windows

任何见识都会受到赞赏。

不，您不能使用VBScript。

您必须进行API调用才能使用窗口执行任何操作。

VB.Net可以进行API调用，并且像VBScript一样内置在Windows中。

这是来自https://winsourcecode.blogspot.com/2019/05/winlistexe-list-open-windows-and-their.html

它列出了所有打开的窗口，您将拥有几百个。可能您只对顶级窗口感兴趣。

EG记事本是5个窗口。 1个顶层，1个“编辑”控制窗口，1个状态栏窗口以及两个标准窗口，所有程序都可以自动获取这些窗口以处理输入中文文本等。

WinList.exe列出打开的窗口及其子窗口的窗口标题，窗口类和EXE文件

请注意，您必须以管理员身份运行才能访问有关高架窗口的信息。

有没有一种方法可以用VBScript计算所有打开的窗口？
