Get page count without open file

Hi Juan :)

for some functions there are versions without have to load the pdf but regarding PageCount this isn't so. I understand that you want to know before really opening a file how large it is.
An experimental idea:
The pagecount is directly visible in the pdf-content. You can try it even with Notepad ;-)
Below i've made few samples to show you how to detect these data.
You'll find this data after:
/N
/Count
and /Type/Catalog/Pages

Cheers and welcome here,
Ingo

Hi Juan :)


uuuups... I'm wrong. Never used it but here's the function you're asking for:
https://www.debenu.com/docs/pdf_library_reference/DAGetPageCount.php
This will feed your needs.
DA means direct access without loading.
What you really should avoid is mixing direct access with normal functions - this won't work.

Hi Juan,

never mix DA and non-DA in one thread.
After QP.DAClose...
you should insert a QP.Free.
Then a new QP = New...
Then Unlock and then Extract and then Free again.

Here'sa sample about using DA-functionality:

Hi Ingo, 

I don't think that internet access is needed to validate the key.  We use a license key in lots of different EXE and DLL files at many customer sites, some of them tightly secured. and nobody has reported any block or asked for how to get past a firewall.  But I have never used a trial version; it might be different.

the image not is, i can´t attach, but says this:

HI ingo,

Did you already search through forum and www.quickpdf.org?

I did it:

Helpful posts from the community here:
http://www.quickpdf.org/forum/using-the-activex-version-with-asp_topic1209.html
http://www.quickpdf.org/forum/activex-to-new-activex_topic2413.html

A short guide from a user long ago:
Hey,
I have quick PDF running on Windows Server 2008 without issue, using the the standard 32bit activeX DLL
Here is how:
- Open IIS Manager
- Click on "Application Pools"
- Click on the name of the application pool that is running the quick PDF website
- Click "Advanced Settings"
- Set "Enable 32-bit applications" to True
Done!
If you are not doing so already I find its best to run all sites under there own application pool.

And at least: Getting started ActiveX Edition:
http://www.debenu.com/wp-content/uploads/Foxit_Quick_PDF_Library_15_ActiveX_GettingStarted.pdf


BTW: Each prob should have an own thread. Who shall find your actual prob at a thread with the title "...page count..."? ;-)

"a short guide from a user" doesn't help?
See "enable application"...

windows wants 64 bit in a special directory and 32 bit in another special directory.
I think in VS you can do the settings for 64 and 32 bit as well.
Think your settings aren't clear but mixed?
If you put the 32-bit-dll and it works it won't be enough to replace the 32-bit-dll with the 64-bit-dll...

At the top, right "search -> advanced search".
