We use VPE via the DLL interface from a 4GL. All has been OK until we moved to XP from Win2000 a few weeks back. We have noticed that the preview was taking a long time to appear.
A debug trace of our application shows that the VpeOpenDoc call was taking 20-30 seconds to complete and return to the application.
Is there a known issue with VpeOpenDoc under XP or is there something that needs to be done?

This issue is not known. However, do you have a default printer installed under XP?

You hit the answer.
I did have a network printer setup however something disconnected the printer. I did a Windows Security Update and that may have done something.
As I was only previewing the reports and not printing it was not obvious there was a printer issue. Your answer made me check a bit further and that seems to have fixed the problem.
Does the engine behave this way if there is a printer problem?

The same delay would occur, if you hit the print-button in any other application, because Windows tries to find the default network printer with a huge timeout.
What VPE does in OpenDoc() is to retrieve some information about the default printer. Internally some Windows API's are called which incorporate the same huge timeout.

VPEOpenDoc network problem
by finn » Tue Dec 19, 2006 2:12 pm
We use VPE to display various documents to the user. But if the local network is disconnected or disabled (due to a VPN connection), the default printer is not available, and the VPEOpenDoc call will take very loooong time (10-20 seconds on my computer).
Is there any way to avoid this problem? Or will IdealSoftware in the near future have a solution?

This is the same problem as above.
The next major release of VPE will not query for the default printer in OpenDoc(), so the timeout will be gone.

This is not a bug (at least not in VPE). The problem is fixed in v4.0 and higher.
