Form automation with PDF's created in Livecycle

Question

Hi,
I'm having a issue getting the fields from a PDF file created in Livecycle. I get the following error once I access a field:
Element not found. (Exception from HRESULT: 0x8002802B (TYPE_E_ELEMENTNOTFOUND))
Is it possible to use the OLE API's to retreive the fields in the Livecycle form? Here is the code in question:
Public Function FillForm(ByVal patient As clsPatient, ByVal isNew As Boolean, Optional ByVal CompletionDate As Date = #1/1/1900#) As String Implements iPDFProcess.FillForm
Dim ds As New DataSet
Dim dr As DataRow
Dim NewFile As String
Dim formApp As AFORMAUTLib.AFormApp
Dim bOK As Boolean
Dim avDoc As Acrobat.CAcroAVDoc
Dim pdDoc As Acrobat.CAcroPDDoc
Try
  'Set the mouse icon to display an hourglass
  System.Windows.Forms.Cursor.Current = System.Windows.Forms.Cursors.WaitCursor
    If isNew = False Then
        ds = GetData(PatientId, CompletionDate)
        If ds.Tables(0).Rows.Count > 0 Then
            dr = ds.Tables(0).Rows(0)
        End If
    End If
    avDoc = CreateObject("AcroExch.AVDoc")
    bOK = avDoc.Open(lTemplateFileName, "NB")
    avDoc.Maximize(1)
    formApp = CreateObject("AFormAut.App")
    If isNew = True Then  'Only fill Demographic data
        formApp.Fields("PatientId").value = patient.PatientId
        formApp.Fields("DateCompleted").value = Format(Now(), "M/dd/yyyy")
        formApp.Fields("PatientName").value = patient.LastName & ", " & patient.FirstName
     end if
     The rest of the code is not shown to save room.
As soon it tried to access a field I get the above error. I also have a problem with the following code in another section of my code (for another PDF form). Here is a segment of the code:
    avDoc = CreateObject("AcroExch.AVDoc")
    bOK = avDoc.Open(lTemplateFileName , "NB")
    avDoc.Maximize(1)
    formApp = CreateObject("AFormAut.App")
    acroForm = formApp.Fields
    If isNew = True then
        For Each f As AFORMAUTLib.Field In acroForm
            Select Case f.Name
                Case "PatientName"
                    f.Value = patient.LastName & ", " & patient.FirstName
                Case "Gender"
                    f.Value = patient.Gender
                Case "DateCompleted"
                    f.Value = format(Now(), "M/dd/yyyy")
                Case "PatientId"
                    f.Value = patient.PatientId
                Case "DOB"
                    f.Value = patient.BirthDate
            End Select
        Next
    Else
It always passes right over the loop as it it can't find the fields. What up with that. Thanks for any help that you can provide.

Apparently the IAC api's will not work with livecycle forms. I just recreated the pdf file in Acrobat alone, and it now works. But this leaves me with other issues such as:
1. How can I represent a Date picker field?
2. A few of our forms created in Livecycle use dynamic forms. I.E. Hiding pages until a checkbox is selected for example. Is it possible to get similar results with just Acrobat/reader?
Thanks for any suggestion or comments.
