TileNotification with image from temporary folder is ignored

Question

Hi,

I'm trying to create a TileNotification using a temporary image, something like this:

var Notifications = Windows.UI.Notifications;
var tileUpdater = Notifications.TileUpdateManager.createTileUpdaterForApplication();
tileUpdater.enableNotificationQueue(true);
var tileXml = Notifications.TileUpdateManager.getTemplateContent(
    Notifications.TileTemplateType.tileWideImage);
var tileImageAttributes = tileXml.getElementsByTagName("image");
tileImageAttributes[0].setAttribute("src", "ms-appdata:///temp/"+filename);
tileImageAttributes[0].setAttribute("alt", filename);
var tileNotification = new Notifications.TileNotification(tileXml);
tileUpdater.update(tileNotification);

But it does not work, no exceptions.

If I use ms-appdata:///local/ instead it works without problems. Any idea?

Thanks!

Juanma

The temp folder may be getting cleared?  You can use process monitor to see what file activity is occuring when it tries to read this folder.

Thanks for your answer. I've checked it with Process Explorer and the file it is not deleted. In fact I can open the temp folder and see all the created files there.

The only different thing I see when using temp folder instead the local one is that explorer.exe tries in one place to create the file in:

C:\Users\jservera\Documents\Visual Studio 11\Projects\msCanvasTest\PaintJS\bin\Debug\AppX\ms-appdata:\temp\test (2).png

Instead of in the folder that is finally created (TempState)

C:\Users\jservera\AppData\Local\Packages\114e256f-bf10-4878-8e41-cf4f7e5f9818_kp7yavnxmsawr\TempState\test (2).png

Maybe a bug or unsupported feature in TileNotifications?

Thanks,

Juanma

Interesting, how about when the file is read?  What do you see different between the local and temp examples?
