简单Google了一下，未果，于是发邮件请教了一下，很快就有了回复。

代码如下:

Path = "C:\test.jpg"

arr = Split(Path,"\")

FileName = arr(Ubound(arr))

FolderPath = Left(Path, Len(Path) - Len(FileName) - 1)

Set objShell = CreateObject("Shell.Application")

Set objFolder = objShell.Namespace(FolderPath)

set objFolderItem = objFolder.ParseName(FileName)

Width = objFolder.GetDetailsOf(objFolderItem, 162)

Height = objFolder.GetDetailsOf(objFolderItem, 164)

Msgbox "Width: " & Width & " Height: " & Height
