我想到的方法有两种。

一种是WMI中的Win32_DesktopMonitor类
复制代码 代码如下:
strComputer = "."
Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\cimv2")
Set colItems = objWMIService.ExecQuery("Select * from Win32_DesktopMonitor",,48)

For Each objItem in colItems
WScript.Echo "ScreenHeight: " & objItem.ScreenHeight
WScript.Echo "ScreenWidth: " & objItem.ScreenWidth
Next

一种是HTML DOM中的screen对象
复制代码 代码如下:
Dim IE
Set IE = CreateObject("InternetExplorer.Application")
IE.Navigate "about:blank"
Set screen = IE.Document.parentWindow.screen
WScript.Echo "ScreenHeight: " & screen.height
WScript.Echo "ScreenWidth: " & screen.width
