[Quickfix-users] Application hangs

[dev13 <jo...@gm...>]

Hi, I was creating a windows application that accepts FIX messages and
publishes messages in string format ("EURUSD:1.4443:1.4444;").

I have attached the piece of code that connects to the FIX MarketData
provider. The problem is if I use 'initiator.block()', then the application
retrieves data from the provider but the application gets stuck i.e., I am
not able to use any of the other controls in the user interface. And if I
don't use 'initiator.block()', the application will exit with a runtime
exception. 

Please advise.

void Application::initConnection()
{
	try
	{
		Application* appln = Application::getInstance();
		FIX::SessionSettings settings = appln->getSettings();
		FIX::ThreadedSocketInitiator initiator(*appln, FIX::NullStoreFactory(),
settings);

		//initiator.start();
		initiator.poll();

		while(!initiator.isLoggedOn())
		{
			Sleep(1000);
		}
		appln->sendMarketDataRequest();
		
		//initiator.block();
		initiator.stop();	
	}
	catch(char *str )    
	{
		ExtLogger.Out("Connection error : %s", str);
	}
}
