Connecting UWP apps hosted by ApplicationFrameHost to their real processes

Question

I am working on an WPF application to monitor my activities on my computer. I use Process.GetProcesses() and some filtering to get the processes I am interested in

Answer 1

About the same code from Chris Johnsson except that I'm not using Process because it doesn't work very well on the UWP app.

Code for start:

new Timer(TimerCallback, null, 0, 1000);

void TimerCallback(object state)
{
    var process = new ProcessUtils.FindHostedProcess().Process;
    string name = string.Empty;

    if (process.IsPackaged)
    {
        var apps = process.GetAppDiagnosticInfos();
        if (apps.Count > 0)
            name = apps.First().AppInfo.DisplayInfo.DisplayName;
        else
            name = System.IO.Path.GetFileNameWithoutExtension(process.ExecutableFileName);
    }
    else
        name = System.IO.Path.GetFileNameWithoutExtension(process.ExecutableFileName);

    Debug.WriteLine(name);
}

And the FindHostedProcess class where I use ProcessDiagnosticInfo instead of Process

public class FindHostedProcess
{
    public ProcessDiagnosticInfo Process { get; private set; }

    public FindHostedProcess()
    {
        var foregroundProcessID = WinAPIFunctions.GetforegroundWindow();
        Process = ProcessDiagnosticInfo.TryGetForProcessId((uint)WinAPIFunctions.GetWindowProcessId(foregroundProcessID));

        // Get real process
        if (Process.ExecutableFileName == "ApplicationFrameHost.exe")
            WinAPIFunctions.EnumChildWindows(foregroundProcessID, ChildWindowCallback, IntPtr.Zero);
    }

    private bool ChildWindowCallback(IntPtr hwnd, IntPtr lparam)
    {
        var process = ProcessDiagnosticInfo.TryGetForProcessId((uint)WinAPIFunctions.GetWindowProcessId(hwnd));

        if (process.ExecutableFileName != "ApplicationFrameHost.exe")
            Process = process;

        return true;
    }
}

Finally reuse Chris Johnson's WinAPIFunctions class.
