QTcpServer Problem

mohsen

I have a problem with QTcpServer. When i send data from a client to server, it disconnects! but when i send from server to client it works fine!
i use write() for sending data and readall() to receive data.
all signals and slots are ok.

Without showing the code, there is little we can do for you, I think.

thanks Andre. i solved the problem by using a bridge class as a thread. i find out that QTCPServer can not separately host tcp connections itself. so i joined another class contained a QTCPSocket object. now i can send and receive data with no problem. also i can have multiple connections to my server now.
if somebody had the same mean i can place the code here :-)

Hello Mohsen,

I am a newbie in QT and it is exactly what I need, I need multiple connection to a server and the server has to send and receive data. Could you post or send me the code.

Thanks a lot

The post you are replying to is a bit older. So there are chances to have delayed or no replies.

You may also have a look to the "Network examples":http://qt-project.org/doc/qt-4.8/examples-network.html Especially the fortune "client":http://qt-project.org/doc/qt-4.8/network-fortuneclient.html and http://qt-project.org/doc/qt-4.8/network-fortuneserver.html are quite good for starting.
