    Hi,
    As far as I know this error could be caused due to accessing a NULL POINTER or invalid memory.

            Hi,

            From the code you posted, neither serveurIP nor serveurPort are initialized

                Then, the calls should be

                @socket->connectToHost(ui->serveurIP->text(), ui->serveurPort->value());@

                        What is strange is that this would compile, so I guess you have member variables with these names in your class ? If so remove you should remove them
