//Call the webservice
QNetworkAccessManager networkManager = new QNetworkAccessManager(this);
connect(networkManager, SIGNAL(finished(QNetworkReply)),SLOT(onPostAnswerDateServer(QNetworkReply*)));
QNetworkRequest networkRequest(GetDateServerTagUrl);
networkRequest.setHeader(QNetworkRequest::ContentTypeHeader,"application/x-www-form-urlencoded");
networkManager->post(networkRequest,postData); -

Don't create a new
QNetworkAccessManagerfor every call call.Your program should only create 1
QNetworkAccessManager. Let every call use the same object. -

Re: QThread::start: Thread creation error: Resource temporarily unavailable (QNetworkAccessManager)Hi JKSH,
Thank you so much.Your solution can solved my problem.
//header.h
QNetworkAccessManager *networkManager;//program.cpp on load
networkManager = new QNetworkAccessManager(this);
connect(networkManager, SIGNAL(finished(QNetworkReply*)),SLOT(onPostAnswer(QNetworkReply*)));//program.cpp on excecute
QNetworkRequest networkRequest(GetDateServerTagUrl);
networkRequest.setHeader(QNetworkRequest::ContentTypeHeader,"application/x-www-form-urlencoded");
networkManager->post(networkRequest,postData); -
