I am new to programming and I am using visual basic express 2010. This is my setup. I have Button1 on Form1. When selected, Form2 opens and displays values from a csv file. The values are displayed on a DataGridView and a DataSet is established so I can keep the values in memory. I was hoping to get some help in editing my code to use an openfiledialog instead of the coded path/filename.
So, Button1 on Form1 initiates OpenFileDialog. Form2 displays the DataGridView and establishes DataSet. My code follows:

"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & _
path & ";Extended Properties=""Text;HDR=No;FMT=Delimited\"""
Dim conn As New OleDb.OleDbConnection(ConStr)
Dim da As New OleDb.OleDbDataAdapter("Select * from " & _
file, conn)
da.Fill(ds, "TextFile")
End If
Catch ex As Exception
MessageBox.Show(ex.ToString)
End Try
DataGridView1.DataSource = ds.Tables(0)
End Sub
End Class
