Word app spell check problem

I've got a program that reads a comment field into a datareader. As it loops through the datareader, it calls a Word app to spellcheck each comment. The comment should be displayed in a textbox when the spell check runs, but nothing shows. I realize nothing will show when there's no corrections because the loop will run too fast to see it, but when it does stop to check, the text should show.
Also, sometimes the datareader (or maybe the spell checker) truncates the comment in the middle of a word, showing a misspelling where there is none. The code's below, thanks.

VB Code:

Private Sub CheckSpell()
        Dim strSql, strPath, strCn As String
        Dim cn As OleDbConnection
        Dim cmd As OleDbCommand
        Dim dr As OleDbDataReader
        Dim iData As IDataObject
 
        strSql = "SELECT DISTINCT comment FROM Main WHERE month = '" & cboMonth.SelectedItem & "'"
        strPath = strRelPath & mstrFilePath
        strCn = strProv & strPath
 
        Try
            objTempDoc = objWord.Documents.Add
            objWord.Visible = False
 
            ' Position Word off the screen...this keeps Word invisible throughout.
            objWord.WindowState = 0
            objWord.Top = -3000
 
            cn = New OleDbConnection(strCn)
            cmd = New OleDbCommand(strSql, cn)
            cn.Open()
            dr = cmd.ExecuteReader(CommandBehavior.CloseConnection)
 
            Do While dr.Read
                txtSpell.Clear()
                txtSpell.Text = dr("Comment")
                'SpellCheck(txtSpell.Text)' Copy the contents of the textbox to the clipboard
                Clipboard.SetDataObject(txtSpell.Text)
 
                ' With the temporary document, perform either a spell check or a complete
                ' grammar check, based on user selection.
                With objTempDoc
                    .Content.Paste()
                    .Activate()
                    .CheckSpelling()
                    ' After user has made changes, use the clipboard to
                    ' transfer the contents back to the text box
                    .Content.Copy()
                    iData = Clipboard.GetDataObject
                    If iData.GetDataPresent(DataFormats.Text) Then
                        txtSpell.Text = CType(iData.GetData(DataFormats.Text), String)
                    End If
                    .Saved = True
                    '.Close()
                End With
            Loop
 
            objTempDoc.Close()
            objWord.Quit()
            dr.Close()
 
        Catch ex As Exception
            MessageBox.Show(ex.Message, "Error Spell Checking", MessageBoxButtons.OK, MessageBoxIcon.Error)
        Finally
            If cn.State = ConnectionState.Open Then
                cn.Close()
            End If
        End Try
    End Sub
