Hi All,

I'm writing an app that prints of batches of documents to clients for posting. The printer uses OMR to collate and fold the documents into envelopes automatically.

The document inputs will either be Word or Adobe Acrobat. I have routines to print off each document type while adding OMR on the fly.

The issue I have is that when the routine for PDF is run, the Adobe file is not closing properly. So when the next clients batch is being printed, there is an error saying that the document is locked by another user or process.

I'm using the Acrobat 7 reference library and have Acrobat 7 installed on my machine (full blown product, not reader,)

I'm closing the PDDocument, the AVDocument and the application in the code and I've even wrote a routine to kill the process to no avail.

Basically my code copies the source file into a new file.
It then parses through the pages building a string called strOMR in the format OMR_?_SeqNO for each page.
Where SeqNo is a number between 0 and 7 relating to the position of the page in the overall batch of documents. If on the last page of the last document, then ? is given the value I (for insert) else S.

I now look in a template of precreated PDF Annots containing the necessary OMR markup and copy the one thats title matches the string I have built onto the page.

Private sub PrintAdobe(sFile as string)
        Dim AcroAVDoc, AcroAVDoc1 As Acrobat.AcroAVDoc
        Dim AcroPDDoc, AcroPDDoc1 As Acrobat.AcroPDDoc

        On Error Resume Next
        MsgBox("PDF Print error:" & Err.Number & ":" & Err.Description, MsgBoxStyle.Critical + MsgBoxStyle.OkOnly)
        Resume Out
    End Sub

I have wrote a routine to go through the system processes on my machine and kill it off but it still sits there.....

Public Sub KillAcrobat()
        Dim myProcess As Process
        On Error Resume Next
        If Process.GetProcessesByName("Acrobat").Length > 0 Then
            'acrobat is still open
            Do Until Process.GetProcessesByName("Acrobat").Length = 0
                'get each instance of Acrobat
                For Each myProcess In Process.GetProcessesByName("Acrobat")
                    'Attempt to close it
                    myProcess.Close()
                    Threading.Thread.Sleep(1000) 'wait either a second 
                    If Not myProcess.HasExited Then 'still not gone
                        myProcess.Kill() ' force closure
                    End If
                    myProcess = Nothing
                Next
            Loop
        End If
        myProcess = Nothing
    End Sub

I've given up and no longer allow the users to specify OMR output with PDF documents. :(

I even tried encapsulating the whole PDF printing in a class object and setting up dispose methods but the same document remained open. :-O

I am also tried there is no option. Please give the solution it will belo more helpful for me.
