Error using ADODB connection & command

[compulove]

Hello all!

I am getting errors when I try to use this adodb.connection and command in my code. The error I am getting is saying that the connection and command are not defined. I read online that depending on your version of vb that you might use the "OLE" connection instead of ADODB but I am new to vb so I really don't know.

I am really confused but I posted my code below....

Please help me or direct me to any sites that might help me with this

Imports MySql.Data.MySqlClient

Public Class classDatabaseRead

    Private sqlConnection As New MySqlConnection
    Private sqlCommand As New MySqlCommand
    Public sqlReader As MySqlDataReader

    Private stringConnection As String = "SERVER=Gemstore;DATABASE=yourdatabase;PORT=3306;UID=user;PWD=password~;"

then in a form or whatever you are calling it from

DIM Query as string = "SELECT auth_lvl FROM user_verification WHERE userID = '" & userIDIn & "' AND password = '" & passwordIn & "';"
 
DIM r as classdatabaseread = new classdatabaseread(query)
while r.sqlreader.read
auth = r.sqlreader.getstring(r.sqlreader.getordinal("auth_lvl"))
end
r = nothing

i saw that you are using the sqlreader, not mysqlreader sorry
