Hi Girish Kardam,
Good night.
I normally use the below connection string in my applications and it works. I use SQL Server authentication. Please be sure that you have the right username and password.
Public Sub TestConnection2DB()
Dim myConnection As New SqlClient.SqlConnection
myConnection.ConnectionString = "Database=dainik;Data Source=10.52.4.10;User Id=sa;Password=sa"
End Sub
I hope it helps you to continue your project.
Best regards,
Daniel Cabarcas
