Can AHK detect when Action Center notifications occur?

[Kilk1]

Hello! I've never used AutoHotkey before but have been told it might be helpful for something I've been wanting to do. Is it possible to set up AHK to run a command whenever the Action Center gets a notification from a given app? Thanks!

AFAICS, no. The only thing I found about that - probably offering some details for a conversion - is this: https://docs.microsoft.com/en-us/windows/uwp/design/shell/tiles-and-notifications/notification-listener

Good luck

BTW, the majority of articles I've done some research on this topic have suggested to check out EventViewer instead.

It looks like the link you gave applies when developing an app. To make sure my question isn't confusing, I'm asking about an already-created app (specifically, TextNow) which sends notifications to the Action Center. Is there a way I could create an event on my computer that can trigger whenever an already-developed app (as opposed to an app I'm programming) sends a notification to the Action Center? Thanks!

Yep, that's what the linked content is about, how to become the (listening) man in the middle. There are a few fantastic members at this forum who might be able to translate/convert that code into something that can be used the way you've requested - or coming up with a completely different way .
So, get your fingers crossed & good luck

Kilk1, here is examples how to use Windows Runtime API in ahk:

I am sure that You can get notifications from action center in loop with UserNotificationListener.GetNotificationsAsync method and then parse them without any problem.
https://docs.microsoft.com/en-us/uwp/ap ... ationKinds_
But set event listener - it will be quite difficult.

Tried to do it but there is memory leaking, therefore I empty working set.
Memory leaking may be because I not correct send enumerations
https://docs.microsoft.com/en-us/uwp/api/windows.ui.notifications.notificationkinds?view=winrt-18362
But despite of that code is working.
Code shows notification send by autohotkey.

; Text is an array because some templates have multiple text elements.

; For Windows 10.0.16299 (and possibly earlier or later versions), the AppID
; must identify an app which has a shortcut on the Start screen, otherwise
; the notification won't display.  AppIDs for desktop apps seem to be the
; path of the executable, with system/known folders replaced with GUIDs.
; If this doesn't work, the Get-StartApps powershell command can be used to
; get a list of AppIDs on the system.
; This assumes AutoHotkey is installed in the default location:

Thanks, @malcev! Since I never used AHK before, I could be confused. To make sure I understand, does this code trigger when a specific app of your choice sends an Action Center notification, or does it trigger whenever any app sends an Action Center notification? Thanks!

[malcev]

Code should trigger only appplication with display name "Autohotkey".

Code: Select all

AppName := "Autohotkey"

But some applications does not have AppInfo, You have to check it by Yourself.
PS I added sleep in loop.

Thanks for doing all this! To make sure I understand, if I 1) get AutoHotkey, 2) use the code you provided, and 3) change "Autohotkey" to the name of the app I want, then it should work?

[malcev]

If Your application has AppInfo then yes.

[Kilk1]

If Your application has AppInfo then yes.

Thanks so much! I'll attempt it in the next few days.

@malcev Hello again! I copied and pasted the code to an AHK script, but it didn't work. I changed the AppName from "Autohotkey" to "TextNow - Unlimited Texts + Calls." Since that didn't work, I changed the AppName to just "TextNow" in case this would count as it's true name, but it still didn't work.

In case what I mean is confusing, I want AHK to work with an app known as TextNow. The Windows version that I use can be downloaded here: https://www.microsoft.com/en-us/p/textnow-unlimited-texts-calls/9n43spjlcxcv?activetab=pivot:overviewtab. This app can be opened in the background. Therefore, even when TextNow is closed, it can still send notifications to the Action Center.

What I want is for TextNow to open its app whenever it sends a notification to the Action Center. How can I do this? Thanks!

When you say, "This code will show You appName if it exists," do you mean it will show me what TextNow's name is? That's not necessarily what I'm wanting to do. What I'm wanting is something that means this:

If TextNow (which is in the background) sends a notification to the Action Center, then open Textnow.

Is there code that accomplishes this goal? If so, thanks!

I think You dont understand how this script works.
Script sends requests in loop for all notifications that are in Action Center panel.
Therefore to detect that current notification is from Your application You have to put its name instead of "Autohotkey".
To detect its name use the last script.

Okay, so the last script will give me the name, and the script before is intended for what I'm hoping for. I'll give it a try now.

Okay, I ran the most recently posted script. Messages appeared saying "Outlook," "SupportAssist," and "Skype." While I do have these apps, I don't know why these three were mentioned but not other apps. What do I need to do from here? Thanks!

[malcev]

You have to remove all notifications from action center.
Then send notification from Your application.
Then run script and get its name.

Aha, it worked! The app's name is "TextNow - Unlimited Text + Calls".

[Kilk1]

And now I put the app's name into the original script, and now it works! Whenever "TextNow - Unlimited Text + Calls" sends a notification to the Action Center, the same notification appears as a popup! I've been wanting something like this for a long time, and now I do. Thank you!

I have one more question: Is there code that could open "TextNow - Unlimited Text + Calls" whenever a notification appears, instead of making a popup? Again, thank you!
