Hi, Why I can't invoke an activex function (with an argument of type IDispatch*)correctly? [Solved]

This is my code:
@
QAxWidget *m_tws = new QAxWidget(this);
m_tws->setControl("MyActivex.Ctrl.1");
m_tws->dynamicCall("connect(int)", 1); //All is oK till here

QAxObject * contractInfo = m_tws->querySubObject("createContract()");

if (contractInfo) {
    contractInfo->setProperty("conId", 7516);
    contractInfo->setProperty("symbol", QString("GE") );
    contractInfo->setProperty("secType",QString("STK") );
    ...
    
    QVariantList params;
    int tickerId = 1;
    params << tickerId;
    params << contractInfo->asVariant();
    params << "mdoff,100,101,104,105,106,107,165,221,225,233,236,258";
    params << 0;
    *m_tws->dynamicCall("reqMktDataEx(int, IDispatch*, QString, int)",  params);*
   //After this call, a signal should be emited by m_tws and sent me the market data. But I received nothing!
