    <p>In Qt I need to send a sqlite file (binary file) up to a website using post. So what I do is that I open the file and try to read the content of it into a QByteArray that I with help of QNetworkRequest can send to the server. I can handle the request as the file is sent to the server but the file is just empty. Am I reading the content of the sqlite file wrong? (I know that the file excist) Can you see anything wrong with my code?</p> <pre><code>QByteArray data; QFile file("database.sqlite"); if (!file.open(QIODevice::ReadWrite)) return; QDataStream in(&amp;file); in.setVersion(QDataStream::Qt_4_6); in &gt;&gt; data ; QString boundary; QByteArray dataToSend; // byte array to be sent in POST boundary="-----------------------------7d935033608e2"; QString body = "\r\n--" + boundary + "\r\n"; body += "Content-Disposition: form-data; name=\"database\"; filename=\"database.sqlite\"\r\n"; body += "Content-Type: application/octet-stream\r\n\r\n"; body += data; body += "\r\n--" + boundary + "--\r\n"; dataToSend = body.toAscii(); QNetworkAccessManager *networkAccessManager = new QNetworkAccessManager(this); QNetworkRequest request(QUrl("http://www.mydomain.com/upload.aspx")); request.setRawHeader("Content-Type","multipart/form-data; boundary=-----------------------------7d935033608e2"); request.setHeader(QNetworkRequest::ContentLengthHeader,dataToSend.size()); connect(networkAccessManager, SIGNAL(finished(QNetworkReply*)),this, SLOT(sendReportToServerReply(QNetworkReply*))); QNetworkReply *reply = networkAccessManager-&gt;post(request,dataToSend); // perform POST request </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
