I'm trying your Memory check tool and my sql server is local on my network with a port.
I log in to sql server in the following way:
whenever I put the port number ",abc" the connect button is disabled.
how can we add a port to server name in this software?
I don't believe that the software currently supports that particular notation. As a workaround, I'd suggest creating an alias and connecting to the instance through the alias. That way, you don't have to enter the port number in the instance field.
Please refer also to the forum post "How to specify the static port when connecting to a SQL Server instance?".
