Try this:

Imports System.Data.Odbc

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
     Dim myConnString As String
     Dim mySelectQuery As String
     myConnString = txtConnStr.Text
     Dim myConnection As New OdbcConnection(myConnString)

     mySelectQuery = txtSQL.Text

     Dim myCommand As New OdbcCommand(mySelectQuery, myConnection)
     Dim i As Int32
     Dim sTemp As String
     Dim sTemp2 As String

     ListBox1.Items.Clear()
     Try
          myConnection.Open()
          Dim myReader As OdbcDataReader = myCommand.ExecuteReader()

          While myReader.Read()
               For i = 0 To myReader.FieldCount - 1
                    Select Case myReader.Item(i).GetType().ToString
                         Case "System.TimeSpan"
                              Dim sTimeSpan As TimeSpan
                              sTimeSpan = myReader.Item(i)
                              sTemp2 = sTimeSpan.ToString

                         Case "System.DBNull"
                              sTemp2 = "null"
                         Case Else
                              sTemp2 = CStr(myReader.Item(i))
                   End Select

                   If i = 0 Then
                        sTemp = sTemp2
                   Else
                        sTemp = sTemp & ", " & Trim(sTemp2)
                   End If
              Next
              ListBox1.Items.Add(sTemp)
              sTemp = ""
         End While
         
         ' always call Close when done reading.
         myReader.Close()
         ' always call Close when done with connection.
         myConnection.Close()
       
     Catch ex As Exception
         MsgBox(ex.Message)
     End Try
End Sub
