      Hi,

      You don't give enough information. What version of Qt are you running on your board ? Which distribution is loaded ? etc.

            This is the error message from my executable file that I ran in terminal...

            root@beaglebone:/home/sqs/Documents# ./Keypad
            QWSSocket::connectToLocalFile could not connect:: No such file or directory
            QWSSocket::connectToLocalFile could not connect:: No such file or directory

            No Qt for Embedded Linux server appears to be running.
            If you want to run this program as a server, add the "-qws" command-line option.
            root@beaglebone:/home/sqs/Documents#

            after that I ran it again with "-qws" but no output appeared.

                  There's an instance to run the application alone..

                      ah.. I mean, the executable file can run in the beaglebone without using X11VNC viewer..
