Thanks for your fast response. and thanks for your time..
the scenario i am working with is a little different.
I am required to open an acrobat form (a template) that contains multiple fields that require to be filled with data from a vfp set of tables.
After that, save the resulting acrobat form file (not the template) into a folder, close the file and close the template.

here is the code I am working with:

lcSrcFName = 'XXXX Contract Merge.pdf'
lcSrcDir = 'c:\temp\docs\'
lcFileName = Forceext(Addbs(lcSrcDir)+Alltrim(lcSrcFName),'pdf')
If File(lcFileName)
gApp = Createobject("AcroExch.App") && acrobat object
gAVDoc = Createobject("AcroExch.AVDoc") && user interface object
If gAVDoc.Open(lcFileName, "RDM Contract")
gPDDoc = gAVDoc.getPDDoc() && underlying pdf document representation
gApp.minimize(.t.)
gApp.Show
gFrmApp = Createobject("AFormAut.App")
loFields =gFrmApp.Fields

lnFields = loFields.Count()
For Each loField In gFrmApp.Fields
lcFldType = loField.Type
lcFldROnly = loField.Isreadonly
lcFldVal = loField.Value
Do Case
......................... do something with field value, type and readonly properties..
Endcase
Endfor

gPDDoc.Save(1,'d:\mydocuments\rdmcontract'+Dtos(Date())+'.pdf')
Endif
If gApp.getnumavdocs >0
gApp.CloseAllDocs()
Endif
gApp.Hide()
gApp.Exit()
Endif

gPDDoc = .Null.
gAVDoc = .Null.
gFrmApp = .Null.
gApp = .Null.
loField = .Null.
loFields = .Null.
loFItem = .Null.
Return

If I hide acrobat, I can not work with form fields..(error is 'not open document'). minimize and show both of them display the document
