I have the following code in my Visual Studio.Net editor:

SqlConnection1.Open()
        ' Dim MySqlConn As New SqlClient.SqlConnection("Server=Maxood;User ID=sa;Password=;Database=Businesses")
        Dim MySqlCmd As New SqlClient.SqlCommand




        MySqlCmd.CommandType = CommandType.Text
        MySqlCmd.Connection = SqlConnection1

        MySqlCmd.CommandText = "INSERT INTO buss_seg values('" & txtEntry.Text & "')"
        MySqlCmd.ExecuteNonQuery()

        SqlConnection1.Close()
When i execute this code , the following error occurs:

An unhandled exception of type 'System.Data.SqlClient.SqlException' occurred in system.data.dll

Additional information: System error.

What is the reason.Why it happened, please help!

code_lover:
If the code below is what you executed then where are:
   1- the Import Namespace statements for System.Data and System.Data.SqlClient;
   2- the Sub Page_Load statement;
 Send complete code.
   3- check to on the line, .ExecuteNonQuery try .ExecuteScalar().

Hope this helps.

imports system.data.sqlclient

and then remove sqlclient below the code.
eg:
replace sqlclient.sqlcommand as sqlcommand

I asked where were the import directives?
<%@ Import namespace="System.Data" %>
<%@ Import namespace="System.Data.SqlClient" %>

What book(s) are you following?
