How to consume a click-event in a Toast-Message? - powershell

Question

I made a powershell code that shows a toast-message with a "yes/no" option. Now I am looking for a way to handle that click-event properly. See below the code I have so far:
cls
Remove-Variable * -ea 0
$ErrorActionPreference = 'stop'
Add-Type -AssemblyName System.Runtime.WindowsRuntime
$null = [Windows.UI.Notifications.ToastNotificationManager, Windows.UI.Notifications, ContentType = WindowsRuntime]
$null = [Windows.Data.Xml.Dom.XmlDocument, Windows.Data.Xml.Dom.XmlDocument, ContentType = WindowsRuntime]
# now lets define a toast-message:
$toastXml = [Windows.Data.Xml.Dom.XmlDocument]::new()
$xmlString = #"
<toast launch = "Test1" scenario='alarm'>
<visual>
<binding template="ToastGeneric">
<text>Title</text>
<text>Message</text>
</binding>
</visual>
<audio src="ms-winsoundevent:Notification.Looping.Alarm" />
<actions>
<action content="yes" arguments="yes" />
<action content="no" arguments="no" />
</actions>
</toast>
"#
$toastXml.LoadXml($XmlString)
$toast = [Windows.UI.Notifications.ToastNotification]::new($toastXml)
$appId = '{1AC14E77-02E7-4E5D-B744-2EB1AE5198B7}\WindowsPowerShell\v1.0\powershell.exe'
$notify = [Windows.UI.Notifications.ToastNotificationManager]::CreateToastNotifier($appId)
$notify.Show($toast)
Here I need a way to wait for the event, when the users clicks the "yes/no" buttons in the toast (or the "x" to close all). It should work without an external DLL, but using e.g. "add_Activated" and an eventHandler like in this c# code:
https://github.com/david-risney/PoshWinRT/blob/master/PoshWinRT/EventWrapper.cs
I thought it should be similar like for the other cs-Wrapper from that PoshWinRT project, which I could finally convert into this:
# replacement for PoshWinRT - AsyncOperationWrapper:
Add-Type -AssemblyName System.Runtime.WindowsRuntime
$asTaskGeneric = foreach($method in [System.WindowsRuntimeSystemExtensions].GetMethods()) {
if ($method.name -ne 'AsTask') {continue}
if ($method.GetParameters().Count -ne 1) {continue}
if ($method.GetParameters().ParameterType.Name -ne 'IAsyncOperation`1') {continue}
$method
break
}
function Await($WinRtTask, $ResultType) {
$asTask = $asTaskGeneric.MakeGenericMethod($ResultType)
$netTask = $asTask.Invoke($null, #($WinRtTask))
$null = $netTask.Wait(-1)
$netTask.Result
}
# sample for async operation:
$null = [Windows.Storage.StorageFile, Windows.Storage, ContentType = WindowsRuntime]
$file = 'c:\windows\notepad.exe'
$info = await ([Windows.Storage.StorageFile]::GetFileFromPathAsync($file)) ([Windows.Storage.StorageFile])
$info
Unfortunately, the coding for that eventWrapper seesm to be a bit more tricky. These are the code-snippets that I could not bring to life, but they may point into the right direction:
$method = [Windows.UI.Notifications.ToastNotification].GetMethod('add_Activated')
$handler = [Windows.Foundation.TypedEventHandler[Windows.UI.Notifications.ToastNotification,System.Object]]::new($toast, $intPtr1)
$handler = [System.EventHandler]::new($toast, $intPtr2)
Especially the second IntPtr-parameter required for creating an eventHandler confuses me totally.
Any input is more than welcome. Many thanks.
