Question

I’ve found this at connection strings.com
http://connectionstrings.com/mysql

Do I need to download connector-net from this site: http://dev.mysql.com/downloads/connector/net/

I recycled the code that I used in connecting vb.net with ms sql:

Imports system.data.sqlclient

idnum = TextBox1.Text
    lname = TextBox2.Text
    fname = TextBox3.Text
    skul = TextBox4.Text

    Using sqlcon As New SqlConnection("Server=localhost;Port=3306;Database=testing;Uid=root;Pwd=mypassword;")

        sqlcon.Open()
        Dim sqlcom As New SqlCommand()
        sqlcom.Connection = sqlcon

        sqlcom.CommandText = "INSERT INTO [student](ID, LASTNAME, FIRSTNAME, SCHOOL) VALUES (@ParameterID, @ParameterLastName, @ParameterFirstName, @ParameterSchool)"

        sqlcom.Parameters.AddWithValue("@ParameterID", TextBox1.Text)
        sqlcom.Parameters.AddWithValue("@ParameterLastName", TextBox2.Text)
        sqlcom.Parameters.AddWithValue("@ParameterFirstName", TextBox3.Text)
        sqlcom.Parameters.AddWithValue("@ParameterSchool", TextBox4.Text)

        sqlcom.ExecuteNonQuery()

    End Using

But I get this error:

A network-related or instance-specific
error occurred while establishing a
connection to SQL Server. The server
was not found or was not accessible.
Verify that the instance name is
correct and that SQL Server is
configured to allow remote
connections. (provider: Named Pipes
Provider, error: 40 – Could not open a
connection to SQL Server)

Please help, what solutions would you recommend to this problem?

This article should get you started:

The VB.NET-MySQL Tutorial – Part 3

The article uses MySQL Connector for .NET…

MySQL Connector/NET is available for
download at
http://dev.mysql.com/downloads/connector/net/.
Download the version that includes an
installer to your local hard-drive and
extract the Zip file.

Double-click the installer file to
begin the installation process.
Perform a complete install to the
default directory.

In the code you have:

conn = New MySqlConnection()
conn.ConnectionString = "server=" & txtServer.Text & ";" _
& "user id=" & txtUsername.Text & ";" _
& "password=" & txtPassword.Text & ";" _
& "database=in_out"
