Title: Settings & close event in C#
Post by: lucian.jp on October 01, 2009, 12:23:03 pm

Hi,

I'm trying to do a little plugin that need to persist the setting. I used Settings.Default, but when restarted Media Center, the setting isn't persisted, the default value is restored. How can I save settings ?

I also noted that using the Notify Track Change and Player state event do not trigger when I close media Center. How can I execute some code when closing the application?

Thanks

I've hooked into MC shutdown by overriding Dispose and the WndProc message.

You need to call Save() on your Settings to have them persisted.

Code: [Select]


void FormClosing(object sender, FormClosingEventArgs e)
{
Properties.Settings.Default.Save();
}

        protected override void WndProc(ref Message m)
        {
const int WM_DESTROY = 0x0002;
            // Listen for operating system messages.
            switch (m.Msg)
            {
// The WM_DESTROY message occurs when the application exits
                case WM_DESTROY:
FormClosing(null,null);
                    break;         
            }
            base.WndProc(ref m);
        }

protected override void Dispose(bool disposing)
{
// unhook the upnp stack
if (disposing)
{
FormClosing(null, null);
}

if (disposing && (components != null))
{
components.Dispose();
}

base.Dispose(disposing);
}


You'll also need to manage settings "upgrades", so Settings are migrated if new (minor) versions of MC are installed by the user.

Code: [Select]

// check for upgrade and migrate user settings
                        string version = mcRef.GetVersion().Version;
if (!version.Equals(Properties.Settings.Default.LastMCVersion))
{
Trace("First Execution of MC " + version);
Trace("Upgrading User Settings");
Properties.Settings.Default.Upgrade();
Properties.Settings.Default.LastMCVersion = version;
Properties.Settings.Default.Save();
}

Thank you very much muchadhesion. It was exactly what I was looking for. Everything works very well now. Teal'c would have given 5 indeeds out of 5.

The following post provides a couple more ways catch the MC Close event:
