I tried to use the component (2.26) to print several pdf's in a service (unattended). While the component does not give any error, there is no pdf printed. Is it not possible to print in unattended mode? (because I already tried several other component, including the one from adobe that give the same negative result)

Hi,

   I would recommend that you go into PDF reDirect Pro >> Preferences >> General >> Debug >> Select (check) the "Generate Log Files". Then, try to create (print) the PDF files unattended. Later, go back into the preferences and take a look at the logs to see if an error code was generated.

   In the logs, the first two letters of each line are from each individual program. You will want to look at the output from "AX" (ie the ActiveX component).

   Please note that v2.5.2 is the latest version, and I do not support the older versions. If it is feasible for you to upgrade, then I would consider it (especially since it is free).

   Cheers!

where the START LOGGING is it should log something

in my own logfile it seems it cannot create the object

AddLog ("Voor creeren van pdfO")
                        Set pdfO = New PDF_reDirect_v25002.Batch_RC_AXD

                        AddLog ("Na creeren van pdfO")
                        If pdfO.LastErrorNumber <> 0 Then

                            AddLog "PrintUtil kon niet gecreëerd worden! " & Format(Date, "dd-mm-yyyy nn:nn") & pdfO.LastErrorDescription & " Error Number =" & Str$(pdfO.LastErrorNumber) & " DLL Error Number =" & Str$(pdfO.ErrorLastDLL)
                        End If
                        If Err.Number <> 0 Then
                           AddLog "Error na Utility_Open_PDF leeg " & Err.Description & " " & Err.Number
                            Err.Clear
                        End If

it logs: "Voor creeren van pdfO" (before creating the object), but never ("Na creeren van pdfO" (after creating). So it must crash in the meantime??

Hi,

   Did you also install PDF reDirect v2.5.2, or just the ActiveX component? They both have to be installed to work properly, and PDF reDirect must be in "Professional" mode, and must be registered, or at least, the free trial not expired.

   Please take another look. If you are still having difficulty, send me the entire log by e-mail to exp -at- exp-systems -dot- com.

   Thanks,

Michel,

I installed all PDF reDirect v2.5.2. And of course registered the dll (otherwise i could not create the object in my code). Pdf redirect was in professional mode (at least I think so). The trial hasnt expired yet! I will send you the complete log file, but there isn't any more (interesting) text than this...

Hi,

   I haven't looked at the log yet, but in the mean time, have you tried running the sample code, for example, either the Excel or the Word ones?

   That will give us an immediate feedback on whether the problem is with the component, or the calling code.

   Also, does PDF reDirect Pro work OK?

   Cheers!

Michel

The sample code works perfectly Michel. The component in my own dll also works perfectly, but NOT when it runs as a service. As far as I can tell the dll (my own) has all the needed permissions and the (NT-)service runs under my own administrator NT account.

As it runs as a service my dll cannot create the object (it logs until your component has to be created and has to do its job). So what could be the cause that the object cannot be created when it runs as a service while it CAN create the object while not running as a service (but directly under my account).

By the way: the part of your log-file that causes a 'permission denied' is NOT the log when running my service. It's when I changed some settings in the GUI, but your told me that wasn't necessary at all. It does not log anything when running the services. I is because the object is never created, so it cannot log I suppose... :-(

Hi,

   It might be because the system account that you are using does not have permission to run ActiveX component. What you could try is to run your service in the security context of a specific user account that is different from the logged-on user or the default computer account. Alternatively, check to see if the user or system account used has the permission to run ActiveX components.

Finally, you may want to make sure that PDF reDirect Pro is registered for the system user (if that is the account that your service is using).

   Please keep in mind that I have never programmed a service, so I am not too familiar of the associated nuances, so my response is a bit of a shot in the dark.

   Cheers!

Michel,

I told you that the service runs under my own account, so that is not the problem ;-). That means the same account I use to test the dll (and where it works).

So it MUST be something in the context of your dll that cannot be done in a service? Starting up a form? Or do you use AcroReader?

Sorry for the slow response. I am programming my own Windows Service using VS2010 to see if I can duplicate your results. More later...

Hi,

Is your server running as a 32 or 64 bit OS? (our ActiveX component is only 32 bit)

Thanks!

Hi michel,

sorry did not get this post.

The problem is on 64 bit system,

any result yet?

Posted By: Michel_K17

Hi,

It definitely will not work in 64 bit mode. Your best bet would be to create a 64 bit service that, in turn, calls a 32 bit executable which calls the ActiveX component (which is also a 32 bit component).

Sorry for the workaround. I have reprogrammed the Printer Port Monitor as a 64 bit component, but I have not done it for the component yet.

Cheers!
