How to make a omnet app start simulation automatically upon execution

[Jingyao Zhang]

I am a freshman with omnet, and have a question.

I find that after executing an omnet app (with QtEnv), one must press the Simulate->run button or type F5 to kick up the simulation. Is there anyway to start simulation automatically without manual triggering?

I've tried some ways, for example, in the self contained samples/tictoc/txc1.cc, I add a construction method with scheduleAt in it as follows:

Txc1::Txc1()

{

    cMessage *msg = new cMessage("tictocMsg");

    scheduleAt(simTime()+1, msg);

    EV << "start simulation !!!!!" << endl;

}

However error happenes when executing it:

  what():  (omnetpp::cModule): Object has no associated cComponentType (maybe omnetpp::cModule is not derived from cModule/cChannel?)

Looks this way does not work:((((

I also tried to write a script that can send F5 signal to the omnet process, but this won't work either.

Is there any way to address this? Really need to start the simulation automatically without manual intervention.

Thanks in advance!
