Access Violations on New Page

   Hi All..

We have been using the library without problem for a year or so. Recently we made some report mods and now we are getting AV's which appear to be generated by the library.

Tracking it down it occurs in uPDFPageTree at line 621 in our version, which is V5.11.

function TPDFPageTree.ResourcesDict: TPDFDictionary;

var

  Obj: TPDFObject;

begin

  Obj := FPageDict.FindValueByKeyName('Resources');

"FPageDict" is not assigned. It doesn't always happen, seeming to depend upon what gui activity there's been in the app.

Has anyone had any experience of this?

I do hope so!

Regards,

Don

	Don, I had once a similar problem. The problem was that I did not checked the return code while loading my PDF document. The document was not loaded, I ignored that error and I run into troubles. You should check your sourcecode for each returned exit code. If everithing was ok, please send me your pdf document and I will officialy log your problem into our bug list. My email: marian_pascalau(at)hotmail.com Regards, Marian

	Thanks for your reply, Marian. However, and I should have already posted this, the fault was not with the library but with our code: we were writing beyond the end of a dynamic array, and it just so happened that the memory we trampled was being used by the NewPage routine. So, to our great relief, no bug in the library.
