Too many open documents

[AndreaCCS]

We have an issue with using the viewer in a high volume automated application where we open a document, get some information and then close the document. After a variable amount of time we get an error when calling

Code: Select all

axCoPDFXcview64.OpenDocument(path, "", out documentID, (int)Interop.PDFXCviewAxLib32.PXCVA_Flags.PXCVA_NoUI);

We get

Code: Select all

System.Runtime.InteropServices.COMException (0x82132775): Exception from HRESULT: 0x82132775
   at Interop.PDFXCviewAxLib64.IPDFXCview2.OpenDocument(String SourceFileName, String OpenPassword, Int32& ID, Int32 Flags)
   at Phoenix.Common.Controls.Viewer.OpenPDF(String path) in 

Getting the error string from this HResult gives

Code: Select all

     Too many documents are already opened

When we use GetProperty("Documents.Count") this shows there are 0 documents open (as expected).

Once we get this error we can't seem to recover. Have you got any idea what is causing this or how we can handle the error better?

Thanks
Andrea

Hi Andrea,

The Viewer requires a lot of handles to deal with PDF files and therefore has a build-in limit of 50 opened files at time.
So there is two possibilities:
- leak of handles (or memory?), which will prevent the Viewer from opening files properly.
- strange bug in counting the number of open files (in that case Viewer will not even try to open file).
Please send us information about the PDFXCView.exe process (see attached screenshot) and prepare a sample which will we can use to try and reproduce the problem at our end.

Regards,
Stefan
