I am using Windows 10 64bit. I installed SQL Server 2014 Express. The SQL Server service is running. Now I am trying to connect to the running SQL Server with HeidiSQL. I am using SQL Server named pipes and it is not working. Can you please help me about how to do it?
If you installed with all defaults, then the server/instance name to use for SQL Server Express would be:
.\SQLEXPRESS
(local)\SQLEXPRESS
localhost\SQLEXPRESS
YourPcNameHere\SQLEXPRESS
Either of those should work just fine
