我有下面的 vbscript.... 执行时它将提供此类“SELECT * FROM Application”中的所有应用程序。我想要的是这些应用程序的计数...我正在寻找这个脚本在 vbscript 或 powerrershell 中...

软件包名称总数.. 假设 app-v 客户端有 10 个不同的应用程序，它应该显示为 10 个应用程序...

Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\microsoft\appvirt\client")
Set colItems = objWMIService.ExecQuery("SELECT * FROM Application", "WQL", _

Function WMIDateStringToDate(dtmDate)
WScript.Echo dtm: 
WMIDateStringToDate = CDate(Mid(dtmDate, 5, 2) & "/" & _
Mid(dtmDate, 7, 2) & "/" & Left(dtmDate, 4) _
& " " & Mid (dtmDate, 9, 2) & ":" & Mid(dtmDate, 11, 2) & ":" & Mid(dtmDate,13, 2))

【解决方案1】：

如果您使用 wbemFlagForwardOnly 标志，您将无法获得 SWbemCollection 项目计数，因此请在没有它的情况下执行查询。这是一个例子：

Set objWMIService = GetObject("winmgmts:")
Set colItems = objWMIService.ExecQuery("Select * From Win32_Process")

WScript.Echo colItems.Count

For Each objItem In colItems
    WScript.Echo objItem.Name
Next
