I just tried to work on the 64-bit version, the result is the same. 2,23 Gb filesize. Clearly, something can be done about this. I ask for help

The QPDF ActiveX library has 32-bit and 64-bit versions, and there is unlikely to be a size limit affecting a 4GB PDF in a 64-bit process, if you have enough real and virtual memory.

LoadFromStream is a Delphi-only API so not in the ActiveX library, but you should not need it if you can use 64-bit from VBA and Access. As far as I can recall Microsoft recommends installing 32-bit Office. But know almost nothing about VBA so maybe another user here can help you with that.

What programming language are you using, and does it support 64-bit applications?  With 32-bit you obviously cannot load such large files into memory all at once, either from a stream or direct. And some QPDF language interfaces do not have streams, either.]]> Sun, 27 Jun 2021 22:41:31 +0000 http://www.quickpdf.org/forum/error-with-loadformfile_topic3929_post15790.html#15790 <![CDATA[Error with LoadFormFile : Yes, the error occurs immediately...]]> http://www.quickpdf.org/forum/error-with-loadformfile_topic3929_post15789.html#15789 Author: Varvarkin

Yes, the error occurs immediately after opening. Randomly, it can open a file in 600 MB and not open it in 300 MB. And a file is not a form, but a book in a printed version for the page layout.
I was thinking how it is possible to work with such large files, for example, to divide, process in parts, but in any case it needs to be edited. And then connect it. But there are no such functions in direct access. 
Can you suggest a solution using LoadFromStream, how to do it, step by step?

Hi Alex,

getting 401 seems to me that you've already used LastErrorCode directly after LoadFromFile?
There's no real solution for this but a 4-gb-form isn't a solution as well ;-)
Perhaps you can split the functionality of your process into several steps...?
Reading the pdf-content into a stream and try the loadFromStream-function?

Cheers and welcome here,
Ingo

Good afternoon! I use the library 16.12. When opening large files with a size from 500MB to 4 GB, the LoadFromFile function returns a 401 error. How to defeat it? How can I increase the available memory? It is required to edit files, direct access will not help here.]]> Sun, 27 Jun 2021 10:26:00 +0000 http://www.quickpdf.org/forum/error-with-loadformfile_topic3929_post15786.html#15786
