Answer 1

    MysqlConn = New MySqlConnection
    MysqlConn.ConnectionString = "server=localhost;userid=root;password=1234;database=dblms"
    Dim READER As MySqlDataReader

    Try
        MysqlConn.Open()
        Dim Query As String

        Query = "Select * from dblms.accounts"
        COMMAND = New MySqlCommand(Query, MysqlConn)
        READER = COMMAND.ExecuteReader
        Dim count As Integer
        count = 0
        While READER.Read
            count = count + 1

        End While
      MysqlConn.Close()

    Catch ex As MySqlException
        MessageBox.Show(ex.Message)
    Finally
        MysqlConn.Dispose()

    End Try

the value in count will be the number of rows in a table :) hope this helped
