BadgeUpdateManager::CreateBadgeUpdaterForApplication() crashes with WinRT originate error - 0x80070490 : 'Element not found.'

Shyam Butani 380

Hello,

I'm trying to show badge icon in the taskbar for my WinUI2 application (WinRT/C++). Below is the code snippet:

    // winrt::init_apartment(apartment_type::single_threaded);

    XmlDocument badgeXml = BadgeUpdateManager::GetTemplateContent(BadgeTemplateType::BadgeNumber);

    auto badgeAttributes = badgeXml.GetElementsByTagName(L"badge");

    if (badgeAttributes.Size() > 0) {

        XmlElement badgeElement = badgeAttributes.GetAt(0).as<XmlElement>();
        badgeElement.SetAttribute(L"value", L"7");
    }

    BadgeNotification badgeNotification = BadgeNotification(badgeXml);

    // Below line crashes
    BadgeUpdater badgeUpdater = BadgeUpdateManager::CreateBadgeUpdaterForApplication();

    badgeUpdater.Update(badgeNotification);

In this code, when the line with BadgeUpdateManager::CreateBadgeUpdaterForApplication() hits, it crashes with the below error:

WinRT originate error - 0x80070490 : 'Element not found.'

Can you please help me to understand the issue here and possible solution for this?

Thanks.

Hello,

Welcome to Microsoft Q&A!

I make the code working now. You could follow my steps.

First, I created a blank C++/Winrt UWP project for testing. Adding the following code in to pch.h .

#include <winrt/Windows.UI.Notifications.h> #include <winrt/Windows.Data.Xml.Dom.h>

Then adding reference in the page:

using namespace Windows::UI::Notifications; using namespace Windows::Data::Xml::Dom;

Then I modified your code a little bit. You could directly get the badge node as XmlElement from badgeXml.

Please try the following code:

XmlDocument badgeXml = BadgeUpdateManager::GetTemplateContent(BadgeTemplateType::BadgeNumber); XmlElement targetElement = badgeXml.SelectSingleNode(L"badge").as<XmlElement>(); targetElement.SetAttribute(L"value", L"7"); BadgeNotification badgeNotification = BadgeNotification(badgeXml); Windows::UI::Notifications::BadgeUpdater badgeUpdater = BadgeUpdateManager::CreateBadgeUpdaterForApplication(); badgeUpdater.Update(badgeNotification);

My test result on Windows 11

Thank you.

Hi @Anonymous

I'm getting the same error with your suggested approach too. Below is the call stack if that helps:

@Shyam Butani Could you please share more information about your scenario? Is your app a blank UWP C++/WinRT project? If not, please try in a blank UWP C++/WinRT project first. Are you testing on Windows 11?

Actually, it is "Windows Desktop Application" project and using WinRT Xaml Island by adding NuGet packages (Microsoft.Windows.CppWinRT and Microsoft.Toolkit.Win32.UI.SDK)

Yes testing on Windows 11.

I've made some test in C++/WinRT desktop apps, windows desktop apps and even WPF, WinUI3 and UWP. The BadgeUpdateManager or BadgeUpdater only works in UWP and WinUI3 applications. I would say that this API is not supported in desktop apps even though it compiles without error.

Any alternative suggestions that I can use to show number badge on taskbar icon?

ITaskbarList3::SetOverlayIcon is there, but we need to manually draw number on top custom icon. It does not seem feasible. Any better approach for this?

I asked some Win32 engineers about this. ITaskbarList3::SetOverlayIcon should be the correct way.

Hello,

Welcome to Microsoft Q&A!

This is a summary for our discussion.

After testing, the BadgeUpdateManager and BadgeUpdater only works in UWP and WinUI3 applications. They are not supported in desktop apps like Win32, WPF,etc. If you want to show number badge on taskbar icon in normal desktop apps, please try win32 API ITaskbarList3::SetOverlayIcon.

Thank you.
