New error in Qt

fari35

My client was working perfectly fine but now when I run it after 6 days it is giving me an error:

moc_tsocket.obj:-1: error: LNK2019: unresolved external symbol "private: void __cdecl Tsocket::sendmessage(class QString,int)" (?sendmessage@Tsocket@@AEAAXVQString@@H@Z) referenced in function "public: virtual int __cdecl Tsocket::qt_metacall(enum QMetaObject::Call,int,void * *)" (?qt_metacall@Tsocket@@UEAAHW4Call@QMetaObject@@HPEAPEAX@Z)

The code for tcpsocket file is:

#include "tsocket.h"
#include"mainwindow.h"
Tsocket::Tsocket()

{

    connect(this, SIGNAL(connected()), this, SLOT(connected()));
    connect(this, SIGNAL(readyRead()), this, SLOT(readdata()));
    connect(this, SIGNAL(disconnected()), this, SLOT(disconnect_ser()));
}

    data=send_str;

 }
QByteArray br = data.toUtf8();
        this->write(br);

}

{

    QByteArray data = this->readAll();

    emit rec_slot(data);
}
void Tsocket::disconnect_ser()
{

    emit gotNewMessage(
                QString("%1")
                .arg("disconnected from server:")
                );
    this->deleteLater();
}
void Tsocket::connected(){
    emit gotNewMessage(QString("%1")
                       .arg("client connected"));

}

Can anyone tell me reason for this error ?

Hi,

Did you add/remove the Q_OBJECT macro from your class declaration ?

Is this a slot ?
