[SOLVED]QUdpSocket & broadcast & Windows7
I am sending a request (broadcast: 255.255.255.255) by UDP to determine who is where in the network. The program works fine under WinXP, Ubuntu but under Windows7 sent to any address other than broadcast (255.255.255.255). Other programs written in C # and VB work.
Maybe you can post some sample code, so that someone with a Win7 box can try it.
Also make sure that neither a firewall nor a virus or malware scanner is in the way. Additionally you might need to have higher privilges for sending broadcasts, but I’m not sure about this, I might be wrong.
According to QTBUG-13516 [bugreports.qt.nokia.com] there has been an issue with UDP broadcasts on Vista.
