Hi I am having trouble with allowing others to connect to my server. I am running server 2008, I have changed all the settings to allow incoming connections and followed a few guides but all seem to have failed miserable.

This connections string works fine to connect to the db locally:

SqlConnection conn = new SqlConnection("Data Source=.\\SQLExpress;Initial Catalog=Food;Integrated Security=SSPI;");

however when I try and substitute it for a ip based connection string:

SqlConnection conn = new SqlConnection("Data Source= ipaddy,1433;Network Library=DBMSSOCN;Initial Catalog=food;");

it completly crashes my program and it won't load at all.

If someone could help would be much appreciated cheers in advance

Can I ask why everyone has now started answering this? It was a year and a half ago.....

you have 2 error

1) use user name of your pc b4 the servername

Data Source=.\\SQLExpress;Initial 

Data Source=PC Username\\SQLExpress;Initial

cos (.) only work with Sql 2000

2) use @ b4 connection string

SqlConnection conn = new SqlConnection(@"Data Source=.\\SQLExpress;Initial Catalog=Food;Integrated Security=SSPI;");

And the Final Connection string will

SqlConnection conn = new SqlConnection(@"Data Source=PC Username\\SQLExpress;Initial Catalog=Food;Integrated Security=SSPI;");

simple way is

drag a datagridview on form
now, see arrow button at top right,
click add new datasource

now in a new window new datasource -> then give name of sql server, username - pwd select database & hit TestConnection button if successful then click ok

in window u will get your connection string copy-paste and use it in code
now u can remove datagridview from form

Happy Coding!

Create a text file (connection.txt) rename it to connection.udl. Open it set and up the connection. Close it and open it again with notepad. The Connection string will be there.
