Probably because you do not have a table named "Project" in your master database to select from. But that is just a guess since you did not ask a question or describe a problem.

Solution 1

Seems like you are connecting to master Database according to the following code...

C#

SqlConnection conn = new SqlConnection("Data Source=DEV156-64; Initial Catalog=master; User Id=sa;Password=BeeSys;");

Then you are getting data from Project Table.

C#

SqlCommand cmd = new SqlCommand("select * from Project", conn);

According to the Error Message, it is quite clear that Project does not exist inside the master Database. Please mention the correct Database in the connection string.

I don't think so. Are you seeing the same Server? Make sure the Server and Database you are looking are correct.

Dude, this is a connection issue. This means your Connection String is wrong or you don't have permissions to connect.
