Simple .net form to open outlook and populate fields?

I'm trying to make a simple form in vb (using visual studio) where my user can enter an email address, attach document(s), and enter a name, then click submit and it opens the an outlook email to where she can preview the email and then click send...this is my start (below), but it doesn't populate.  If I use With and then automate the send, it does fine, but when i remove the send it doesn't populate.  What am I missing?


Private Sub Button1_Click(sender As Object, e As System.EventArgs) Handles Button1.Click
        Dim Outl As Outlook.Application
        Outl = CreateObject("Outlook.Application")

        Dim olMail As Outlook.MailItem
        olMail = Outl.CreateItem(Outlook.OlItemType.olMailItem)

        olMail.To = "yes@ys.com"
        olMail.Subject = "About our meeting..."
        olMail.Body = _
             "Dear"

        If Outl IsNot Nothing Then
            Dim omsg As Object
            omsg = Outl.CreateItem(0) '=Outlook.OlItemType.olMailItem'
            'set message properties here...'
            omsg.Display(True) 'will display message to user
        End If

    End Sub
