Hi,
I was trying to make a simple version of windows task manager. I want to list working applications in my program. Not all of them, only programs listing on taskbar.

Try to eliminate with IsWindowVisible or IsIconic. But this code listing like TextInputHost, ApplicationFrameHost etc. But I only want to see like task manager not detailed one. I need good ideas and if anyone help me I would be glad.

My Task Manager showing that programs:

But I want to list that ones:

What I have tried:

[DllImport("user32.dll")]
        [return: MarshalAs(UnmanagedType.Bool)]
        static extern bool IsWindowVisible(IntPtr hWnd);
        [DllImport("user32.dll")]
        public static extern bool IsIconic(IntPtr hWnd);

Process[] processes = Process.GetProcesses();
foreach (var proc in Process.GetProcesses())
{
if (proc.MainWindowHandle != IntPtr.Zero && proc.MainWindowTitle != "")
{
}
}
