Unfortunately, there really isn't a straight-forward way to do it. UFT doesn't allow regular expressions for numeric properties like height or width. We have a lot of objects in our application with identical properties except that when one is hidden, the width is set to 0. I use a function with code similar to this to find the one I want.
Set objDesc = Description.Create
objDesc("html tag").Value = strHTMLTag
objDesc("name").Value = strName
Set colObjects = objPage.ChildObjects(objDesc)
blnFound = false
For intIndex = 0 to colObjects.Count - 1
Set objActive = colObjects.Item(intIndex)
If objActive.GetROProperty("width") > 0 Then
blnFound = true
If blnFound Then
Print "Found it"
Print "No object for you"
