Item cannot be found in the collection corresponding to the requested name or ordinal

where is your rs.open statement?

Your code snippet is incomplete, so it is difficult to tell what code is elsewhere with regards to the database connection.  However, while you declare the sql string, there is no declaration to actually populate the rs recordset with the result of this query?

Code should be something like attached (I presume the bits I've added at the front you already have).

' Connect to database
Dim ConnectionString As String = "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=c:\\Northwind.mdb"
Dim conn As Connection = New Connection
Dim connMode As Integer = ConnectModeEnum.adModeUnknown
conn.CursorLocation = CursorLocationEnum.adUseServer
conn.Open(ConnectionString, "", "", connMode)
Dim cmdType As Integer = CommandTypeEnum.adCmdText
 
 
Dim sql As String
sql = "select * from [Student_Outcomes] where [OutcomeDate]  = #" & ListView2.SelectedItems.Item(0).SubItems(1).Text & "# And [StudentID] = " & TextBox7.Text
Debug.Print(sql)
' Run query
Dim rs As _Recordset = conn.Execute(sql)
studentnotes.Text = ""
studentnotes.Text = (rs.Fields("OutcomeNotes").Value)
rs.Close()

Select allOpen in new window

ok guys i have got it working now thanks so much, how could i have miss that but now i am getting another error that i thought the code i am using should have fixed

{"Either BOF or EOF is True, or the current record has been deleted. Requested operation requires a current record."}

is below

Private Sub ListView2_MouseHover(ByVal sender As Object, ByVal e As System.EventArgs) Handles ListView2.MouseHover
        Dim rs As New ADODB.Recordset
        Dim sql As String
        sql = "select * from [Student_Outcomes] where [OutcomeDate]  = #" & ListView2.SelectedItems.Item(0).SubItems(1).Text & "# And [StudentID] = " & TextBox7.Text
        Debug.Print(sql)
        rs.Open(sql, cnn1, ADODB.CursorTypeEnum.adOpenDynamic, ADODB.LockTypeEnum.adLockPessimistic)
        studentnotes.Text = ""
        If Not DBNull.Value.Equals(rs.Fields("OutcomeNotes").Value) Then
            studentnotes.Text = ""
            studentnotes.Text = rs.Fields("OutcomeNotes").Value
        Else
            studentnotes.Text = "Currently There are no notes to Display for this Student"
            rs.Close()
        End If
 
        rs.Close()
    End Sub

i have also tried it like this
    Private Sub ListView2_MouseHover(ByVal sender As Object, ByVal e As System.EventArgs) Handles ListView2.MouseHover
        Dim rs As New ADODB.Recordset
        Dim sql As String
        sql = "select * from [Student_Outcomes] where [OutcomeDate]  = #" & ListView2.SelectedItems.Item(0).SubItems(1).Text & "# And [StudentID] = " & TextBox7.Text
        Debug.Print(sql)
        rs.Open(sql, cnn1, ADODB.CursorTypeEnum.adOpenDynamic, ADODB.LockTypeEnum.adLockPessimistic)
        studentnotes.Text = ""
        studentnotes.Text = rs.Fields("OutcomeNotes").Value
        rs.Close()
    End Sub
and get a type 'DBNull' to type 'string' is not valid

    Private Sub ListView2_MouseHover(ByVal sender As Object, ByVal e As System.EventArgs) Handles ListView2.MouseHover
        Dim rs As New ADODB.Recordset
        Dim sql As String
        sql = "select * from [Student_Outcomes] where [OutcomeDate]  = #" & ListView2.SelectedItems.Item(0).SubItems(1).Text & "# And [StudentID] = " & TextBox7.Text
        Debug.Print(sql)
        rs.Open(sql, cnn1, ADODB.CursorTypeEnum.adOpenDynamic, ADODB.LockTypeEnum.adLockPessimistic)
        studentnotes.Text = ""
        studentnotes.Text = rs.Fields("OutcomeNotes").Value
        rs.Close()
    End Sub

BOF or EOF true basically means that your SQL statement isn't returning any data.

You have a debug statement for the sql.  Please paste the generated SQL here - either there is a problem with your generation of the SQL, or there is actually no data that matches your query.

that error means that you got no records back:

  Private Sub ListView2_MouseHover(ByVal sender As Object, ByVal e As System.EventArgs) Handles ListView2.MouseHover
        Dim rs As New ADODB.Recordset
        Dim sql As String
        sql = "select * from [Student_Outcomes] where [OutcomeDate]  = #" & ListView2.SelectedItems.Item(0).SubItems(1).Text & "# And [StudentID] = " & TextBox7.Text
        Debug.Print(sql)
        rs.Open(sql, cnn1, ADODB.CursorTypeEnum.adOpenDynamic, ADODB.LockTypeEnum.adLockReadOnly)
        studentnotes.Text = ""
        if not (rs.eof and rs.bof) then
           studentnotes.Text = rs.Fields("OutcomeNotes").Value
        end if
        rs.Close()
    End Sub

ok mate thanks so much i am more then happy to give you 500 point for the extra help but bnow i am gettting

Conversion from type 'DBNull' to type 'String' is not valid.
on hte same line

any help mate please

that means that the value returned could be NULL.
you have 2 options:

* make the NULL value replaced by the query
sql = "select NZ(OutcomeNotes, 'N/A') OutcomeNotes from [Student_Outcomes] where [OutcomeDate]  = #" & ListView2.SelectedItems.Item(0).SubItems(1).Text & "# And [StudentID] = " & TextBox7.Text
 
* handle the NULL value in the .net code
Private Sub ListView2_MouseHover(ByVal sender As Object, ByVal e As System.EventArgs) Handles ListView2.MouseHover
        Dim rs As New ADODB.Recordset
        Dim sql As String
        sql = "select * from [Student_Outcomes] where [OutcomeDate]  = #" & ListView2.SelectedItems.Item(0).SubItems(1).Text & "# And [StudentID] = " & TextBox7.Text
        Debug.Print(sql)
        rs.Open(sql, cnn1, ADODB.CursorTypeEnum.adOpenDynamic, ADODB.LockTypeEnum.adLockReadOnly)
        studentnotes.Text = ""
        if not (rs.eof and rs.bof) then
          if not IsDBNull(rs.Fields("OutcomeNotes").Value)
           studentnotes.Text = rs.Fields("OutcomeNotes").Value
          end if
        end if
        rs.Close()
    End Sub
