How to Supply the form field values to a pdf form when loading it

Question

I am working on a web site project using Asp.net where the user has to fill in a PDF eform in acrobat reader. Then when he clicks on submit it returns to my asp.net app and the PDF form supplies the values back to my asp.net app. So my asp.net app has the values that were filled in the PDF form and can save those values and work with them...
OK.
What I need to know is when I am in my asp.net app, and the user wants to go back and reopen the same form, from my asp.net app..... then how do I pass back the values that were saved back to the PDF form??
I know if I had a way to pass the values to the PDF form in some way then in the Doc.open or doc.load event of the form I could easily write a little javascript to plug in the values in the PDF form fields.
but how do I pass those values from my asp.net app to my PDF form???
thanks

Thanks bcweed for all the info. I fixed my problem, it had something to do with LiveCycle Designer. If I just use Acrobat to add the form fields, then the FDF works fine. As to your situation with the SavToBuf, that happens to be the method that I am using, so I will just post my code here, and maybe you can pick out what is different from yours. The Response.BinaryWrite(FDFin.FDFSaveToBuf)is at the bottom.
Sql = "SELECT * FROM Invoices" & WHERE
Set Conn = Server.CreateObject("ADODB.Connection")
Conn.Open Db_Conn_Str
Set Rs = Server.CreateObject("ADODB.Recordset")
Rs.Open Sql, Conn, adOpenStatic, adLockReadOnly, adCmdText
If Not Rs.EOF Then
End If
Set FdfAcX = Server.CreateObject("FdfApp.FdfApp")
Set outputFDF = FdfAcX.FDFCreate
'VendorID = VendorName = VendorNum = InvoiceDate = PreparedBy = ""

For I=0 To Rs.RecordCount-1

VendorID = VendorID & Rs.Fields("VendorID") & ", "

VendorName = VendorName & Rs.Fields("VendorName") & ", "

If InStr(InvoiceNum,Rs.Fields("InvoiceNumber")) = 0 Then
