What can I do to deal with the problem showed in the picture. I try to add server in the qstudio.But I do not know how to deal with this problem .Thanks
you probably need to start the kdb+ process itself on the localhost, listening on port 5000, e.g. from the shell
q -p 5000
if you have not already downloaded kdb+, you can get a free 32bit version from kx.com.
