Hello! Threshe,
Yes buddy i have to use the same to acheive it. But i am able to use Qt4 can you please broaden my info over how actually did you use QUdpSocket. I mean it just connects you to the host. How can you run the program, call its functions, send data, recieve data n all?
OR can i use QProcess/QThread????
