fatal error importing progid: 'PXCComLib.CPXCControlEx'

[nick.tucker]

Hi

I'm transferring my development environment onto a new workstation running Windows 8 and having installed the 'PDF-XChange 4 API Setup' (PDFXAPI4.EXE) and now cannot compile my project which compiles fine on the previous Windows 7 rig with the same API installed. The following errors are produced:

error C1103: fatal error importing progid: 'PXCComLib.CPXCControlEx'
error C3501: there is no typelib registered for ProgID 'PXCComLib.CPXCControlEx'

for the following C++ source line:

#import "progid:PXCComLib.CPXCControlEx" rename_namespace("PXC"), named_guids

I have used Sysinternals' Process Monitor which shows the new workstation is attempting to access registry key:

HKCU\Software\Classes\PXCComLib.CPXCControlEx

Which exists on the old rig but not the new one.

What am I doing wrong?

Looks like it was registered only in HKLM part of the registry.

Please run
pdfSaver4.exe /RegServer

to register the COM server again.

Hi Ivan

Thanks for the reply, I've run

pdfSaver4.exe /RegServer

as suggested, from a command prompt run as administrator, i.e. elevated, but that has made no difference. I've also tried unelevated just in case and that makes no difference either.

The file version of pdfsaver4.exe is 4.0.201.0 if that helps - it's from a freshly downloaded copy of the PDF-XChange 4 API Toolkit.

Hi,

Can you please try installing this installation and see if that helps;

Hi - I have tried installing the specified update and it still doesn't work.

Hello Nick,

I've passed this topic to Ivan once again and have asked for his further advise. We will post back here when there are some further news.

Can you please try import by libid instead of prodid?

Code: Select all

#import "libid:AAF4C859-3ACD-4D27-88E6-B163C8D81BEC" rename_namespace("PXC"), named_guids

It that doesn't help, I would like to have a remove session via TeamViewer to check on your computer why it is not registered properly.

#import by libid compiles, but is that the 'correct' form, or does #import by progid not working suggest something is not as it should be?

Also, using the libid form, I'm getting compiler warnings as below - obviously I can use a #pragma to suppress them, but that's also worrying:

view.h(25): warning C4192: automatically excluding '_FILETIME' while importing type library 'AAF4C859-3ACD-4D27-88E6-B163C8D81
BEC

Thanks for progress anyway!

Hi Nick,

Assuming you are using MS Visual Studio as your dev environment, what is the version of your IDE?

that's also worrying:

view.h(25): warning C4192: automatically excluding '_FILETIME' while importing type library 'AAF4C859-3ACD-4D27-88E6-B163C8D81

This warning means the #import detected that _FILETIME identifier has been defined somewhere above in the compilation unit and therefore no need to generate its definition from the type library. You can override this default behavior with no_auto_exclude #import attribute. But doing so you will probably meet some issues while using imported interfaces because syntactically identical type definitions in different namespaces are treated as different types by the compiler.

Thanks for the extra details Nick!

I've passed that to Roman and he will post his further thoughts here a bit later.

Thanks for the info, Nick.

Please verify that HKLM\Software\Classes\PXCComLib.CPXCControlEx registry key is present on your system.

As Ivan mentioned, it would be better to get remote access to your system and do live debugging. Site forum has too big lag to be used as an efficient debug channel.

Hi Roman

I have just confirmed that HKLM\Software\Classes\PXCComLib.CPXCControlEx registry key is present on my system.

Remote access would be possible, just a question of how to co-ordinate given I'm in the UK.

Many thanks

Nick

Roman is based in our European office so is just a couple of hours ahead of you - please suggest a couple of dates/times when this would be convenient ..

Please email this to support@pdf-xchange.com - for the attention of Roman with a link back to this forum thread and we will try and ensure that this is accomdated.

Thanks

[nick.tucker]

Will do, although I am about to take a week's holiday so let's defer this until I get back.

Thanks
