Hi,

Im working on WinUI3 desktop application in cpp. I want to convert HRESULT error code to human-readable text (Like Format Message in Win32). We can use Format Message, which only prints the HRESULT error code derived from Win32, not all HRESULT error codes.

What is the best way to convert HRESULT to human-readable text, which covers all the error codes.

    Hi,

    Welcome to Microsoft Q&A!

    You could try to use winrt::hresult_error to convert HRESULT error code.
