Vbscript detect button in an new IE window - vbscript

Question

I have a vbscript that opens an webpage, then clicks a button. That button opens a new popup webpage on a new window (notice: window not tab).
I want after my script press the button and open a new window, to detect and click the button called id="pagesHeaderLikeButton" in that new window, then close that window.
My script so far:
Set IE = createobject("internetexplorer.application")
strURL = "website"
Do While True
IE.navigate strURL
IE.Visible = true
Do While (IE.Busy Or IE.READYSTATE <> 4)
WScript.Sleep 1000
Loop
Set Popupbutton = IE.Document.GetElementsByClassName("single_like_button btn3-wrap")
for each button in Popupbutton
button.click
WScript.Sleep 5000
exit for
objWindow.Quit
WScript.Sleep 5000
next
Loop
Also to notice. I want to do it like this because the popup window allways will have a new url.

Answer 1

For Each wnd In CreateObject("Shell.Application").Windows
If InStr(wnd.Name,"Internet") Then
if InStr(wnd.Document.URL,"facebook.com") Then
Set IE2 = wnd
Exit For
End If
End If
Next
The above script will find any opened IE with the URL: facebook.com/*** and will set IE2 to be that opened IE.
So to press the button:
Set Butlike = IE2.Document.getElementsById("pagesHeaderLikeButton")
For Each btn In Butlike
button.click
Next
