Dim myReport As New ReportDocument
Dim myData As New DataSet
Dim conn As New MySqlConnection
Dim cmd As New MySqlCommand
Dim myAdapter As New MySqlDataAdapter
conn.ConnectionString = _
"server=127.0.0.1;" _
& "uid=root;" _
& "pwd=12345;" _
& "database=test"
Try
conn.Open()
cmd.CommandText = "SELECT city.name AS cityName, city.population AS CityPopulation, " _
& "country.name, country.population, country.continent " _
& "FROM country, city ORDER BY country.continent, country.name"
cmd.Connection = conn
myAdapter.SelectCommand = cmd
myAdapter.Fill(myData)
myReport.Load(".\world_report.rpt")
myReport.SetDataSource(myData)
myViewer.ReportSource = myReport
Catch ex As Exception
MessageBox.Show(ex.Message, "Report could not be created", MessageBoxButtons.OK, MessageBoxIcon.Error)
