Adobe Acrobat

Hi,

I'm working on an application that prints batches of documents with OMR in VB.net (OMR - are markings that allow the OMR enabled printer to fold documents etc into envelopes automatically)

As I'm printing these documents in batches for a number of people, I need to work on a document, print it with the OMR marks and then close/release it, move on to another document and then come back to the document when I'm on the next person and so fourth.

However, despite closing the PDDoc and AVDocument the document is still being kept open by Acrobat and an Acrobat process is running in my task manager.

Here is a brief snap shot of my code:

Public Sub PrintAdobeOMR(ByRef sFile As String)
           dim AcroAVDoc, AcroPDDoc as Object
 
             AcroAVDoc = CreateObject("AcroExch.AVDoc")
             AcroAVDoc.open(sFile, Dir(sFile))
             AcroPDDoc = AcroAVDoc.GetPDDoc
             '.... OMRStuff happens here
             AcroAVDoc.PrintPagesSilent(0, AcroPDDoc.GetNumPages- 1, 2, False, False)
            'close up PDDoc
            AcroPDDoc.Close()
            ReleaseActiveX(AcroPDDoc) 'code to try and release COM/ActiveX objects
            AcroPDDoc = nothing
            'close AV Doc
            AcroAVDoc.Close(True)
            ReleaseActiveX(AcroAVDoc)
            AcroAVDoc = Nothing
end sub
 
Public Sub ReleaseActiveX(ByVal o As Object)
        'ensures active X / Com objects are closed
        Try
            System.Runtime.InteropServices.Marshal.ReleaseComObject(o)
        Catch ex As Exception
        Finally
            o = Nothing
        End Try
    End Sub

As I said, the next time the application goes to open the document, I get an error saying the file is already open in Acrobat. I'm probably missing something simple but what....

Thanks
