Getting child PIDs of ApplicationFrameHost.exe

[RtheBen]

Hello everyone,

before posting this one I spent 2 hours searching the web for an answer, so I apologize if some obscure post exists about this topic.

I'm trying to get the PID of a Microsoft Edge window/website (any site would do as an example, take wikipedia for example).

 

In this examle I have Edge opened with 2 tabs:

"https://en.wikipedia.org/wiki/Main_Page"

and

"https://support.microsoft.com/en-us"

 

well if I use WinGetProcess("Wikipedia) I get the ApplicationFrameHost.exe PID if Wikipedia tab is active, (the same PID I can see in the task manager details)

whereas I get the "true" Wikipedia window PID if wikipedia is not active(Microsoft support i active instead).

I understand that Microsoft Edge tabs and windows are "behind" the ApplicationFrameHost in windows 10 by now,

 

But How can I get the children PIDS using the window title?

My sample code is as simple as:

#include <MsgBoxConstants.au3>
#include <WindowsConstants.au3>

    Local $nm="Wikipedia"
    ;Local $nm="Microsoft"
    Local $r = WinGetProcess($nm)
    $i=0
    msgbox(0,"",$r)

 

The "true" child PID for wikipedia would be 16752 (as per task manager), but I get 8272 which is the ApplicationFrameHost.exe instead.

Here is the screenshot of the task manager, it's in Italian but ok, you get it

and this is the screenshot for the ApplicationFrameHost.exe PID

Try this :

#include <Constants.au3>
#include <Array.au3>

MsgBox ($MB_SYSTEMMODAL,"",_GetEdgePID ("Wikipedia"))

Func _GetEdgePID ($sName)
  Local $ar = ProcessList ("MicrosoftEdgeCP.exe")
  Local $aw = WinList($sName)
  Local $iPID, $iIdx
  For $i = 1 to $aw[0][0]
    $iPID = WinGetProcess ($aw[$i][1])
    $iIdx = _ArraySearch($ar,$iPID,1,0,0,0,1,1)
    If $iIdx > 0 Then Return $iPID
  Next
  Return -1
EndFunc

You will have to add error checking in the function...
