Import of XFDF-file hangs in windows 7

[haviital]

Hi,

I happens very often in our system that the process hangs when I import an XFDF file on existing PDF by calling:

Code: Select all

				
szScriptCommand.AppendFormat( L"this.importAnXFDF(\"%s\");", szPathAndFileName );
CComBSTR bsScript( szScriptCommand );
CComBSTR bsResult;
m_ppdfxchange->RunJavaScript( bsScript, OUT &bsResult.m_str, 0, PXCVA_NoUI | PXCVA_Sync );

It never returns from RunJavaScript(). In Process Monitor logs I can see that it starts reading the file. This happens only in Windows 7 (Win7 Ultimate, SP1, 64-bit), Windows 8 works ok.
In our system there can be several XFDF "layers" that are loaded on the PDF for viewing.

I am using the latest PDF-XChange SDK.

Br,
Hannu

One correction: I just checked that we are using the version 2.5.213.0 of PDFXCView.exe and PFDXViewAx.dll binaries. So we do not use the very latest version, if it matters related to this error.

Here is the output of the Task Manager dump of the hanging PCFXCView.exe process, analyzed with WinDbg / "!analyze -v". Looks like it is waiting for an event(s). As I do not have the symbol files for PDFXCView.exe, I do not know which event that is.

Code: Select all

Hello Hannu,

Thanks for your report. Can you please first try with build 214.1 and see if that works, and then please also try with the stand alone Viewer (the end user version) and check if it hangs in there as well.

Then please provide us with a sample pdf + .xfdf for testing here at our end. If the files are sensitive you can send them to support@pdf-xchange.com with a link back to this forum topic.

Regards,
Stefan

Hi, Hannu.

May be it is the same issue:

https://forum.pdf-xchange.com/ ... 36&t=19719
- we fixed it already and fix will be available in the new build (upcoming).

Best
Regards.

Hi,

Thanks for a very quick resolving!

Yes, it looks very much that it is the same bug as mine. The bug occurs easily when doing PDF loading and XFDF loading in fast sequence. When can we expect a new version containing the bug fix?

Hi Hannu,

When can we expect a new version containing the bug fix?

Short answer - Yesterday

We just released build 214.2 of the Viewer SDK - so please download it and give it a try:

Wow,

this must be a world record of product support in reacting to customer needs Well done!

I could not get it to hang any more. We will still test it, but looks very promising.

Hannu

Glad to hear that Hannu!

And wishing you all your attempts to hang the SDK would be unsuccessful

Stefan
