I'm using Quick PDF Library 8.16

Any one encounter this bug in delphi7?

QP.LoadFromFile(f)=0

and QP.LastErrorCode is 0, this is not define in the reference guide.

and in Quick PDF Library 7.xx QP.LoadFromFile is 1.

Hi Purple!

This has to to with ansi strings and unicode strings.
QP handling has changed in this point.
It depends on what your dev-environment expects.
Try the LoadFromFileA and then it should work.
If you want to know more details try the search function
above and search with LoadFromFileA.

Cheers and welcome here,
Ingo

What development environment are you using ? If it is PowerBasic, PowerBuilder or WinDev then you may need to use the LoadFromFileA function as Ingo suggested.

Is QP.UnlockKey successfully returning 1 ? If it is then you don't need to use the LoadFromFileA function.

LoadFromFile errors can also be created by malformed PDF files. You may need to send us the PDF file via the official support forums and we can see what could be causing the error.

Hi Andrew!

Value 1 comes from version 7.xx - there was only one version from LoadFromFile.
So he should try LoadFromFileA ;-)

Cheers, Ingo

I use Quick PDF Library 8.16 without fullsource code. I can not use the qp"LoadFromFileA" function.

The filename is unicode, I send the filename as widestring to qp"LoadFromFile", it return false,

and I change filename to A-Z string, send string to qp"LoadFromFile", and it works.

Is this a bug? thank you

Can you please create a support ticket at http://www.quickpdflibrary.com/support/support-query.php - http://www.quickpdflibrary.com/support/support-query.php When you receive a ticket number then send a reply email and attach the problem file.

I will look at the PDF to see what the problem could be. I see you are using Delphi 7 so the LoadFromFileA function doesn't apply in this case.

I assume that QP.UnlockKey is returning 1 also ? If not then the licence key is not valid for QPL 8.xx for some reason.

Andrew.
