[Quickfix-developers] Converting message to string

[crazy4venu <cra...@gm...>]

Dear All,

 I am trying to convert the message from below function to string data 

void Application::onMessage(const FIX42::ExecutionReport& mesg, const
FIX::SessionID& sid)
{

	std::cout<<"On Message Execution Report"<<mesg<<std::endl;
      std::string str;

mesg.toString(str);
printf("Message string is %s",str);



}


but my application crashes when i do in this manner.

is it possible to convert the message data in execution report to string ?

Regards
tinnu

I guess it crashed not because ExecutionReport failed to convert to string,
but because you pass a std::string object to printf. Try to use std::cout
instead of printf, or pass str.c_str() to printf.

hi derekldn,

Thanks for the support. its great to have support from you.

sorry for next query, as i see sometimes when i enter NewSingleoder 


i get this output in toApp()

OUT:
8=FIX.4.2☺9=137☺35=D☺34=554☺49=venu☺52=20080831-16:20:26.687☺56=MRKTC-EXCH☺11=12☺21=1☺38=1000☺40=1☺54=1☺55=goog☺59=0☺60=20080831-16:20:04☺10=179☺

but i don't see the execution report in fromApp or in onMessage(const
FIX42::ExecutionReport& mesg, const FIX::SessionID& sid).

i don't see anything appearing in event log.


Regards
tinnu.
