{{Quickfixn}} File-Lock Problem with reconnect ...

[Philipp Rümmele]

Hello,

how do i close a fix session, so that it doesn't lock the store files ?
I get an error - when i try to reconnect - File is locked by an other process...

Error Message:

Der Prozess kann nicht auf die Datei "c:\FixConfig\store2\FIX.4.4-T091-PXMD.header" zugreifen, da sie von einem anderen Prozess verwendet wird.
   bei System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)

In my app - i have buttons to start/stop the connection to a FIX Server

        private void btnStart_Click(object sender, EventArgs e)
        {
                // Event für DebugText
                application_Pricing.dbgChanged += new TradeClientAppPricing.DebugMessageHandler(dbg);
                // Event für DataOutput
                application_Pricing.DataChanged += new TradeClientAppPricing.DataMessageHandler(getData);
                // Objekt für Speicher
                storeFactory_Pricing = new QuickFix.FileStoreFactory(settings_Pricing);
                // Objekt für Logging
                logFactory_Pricing = new QuickFix.ScreenLogFactory(settings_Pricing);
                // Objekt für Netzwerkverbindung
                initiator_Pricing = new QuickFix.Transport.SocketInitiator(application_Pricing, storeFactory_Pricing, settings_Pricing, logFactory_Pricing);
                // Verbindung an TradingClient übergeben
                application_Pricing.MyInitiator = initiator_Pricing;
                // Verbindung starten
                initiator_Pricing.Start();
                }
private void btnStop_Click(object sender, EventArgs e)
{
        // Netzwerkverbindung trennen
         initiator_Pricing.Stop();

                application_Pricing = null;
                initiator_Pricing = null;
                logFactory_Pricing = null;
                storeFactory_Pricing = null;

}

Any hints, ideas how to stop this file locking ?

Thanks and greetings
Philipp
