Hello,

I'm so new programming and it's my fisrt time with Debenu QPL. Is there any example I can use to show me the use of the library in C++? I'm working in code blocks right now. The only examples I can find are VS ones.

Thanks

Hi,

using the advances search option above on this page i found this sample from Bob Hall:
http://www.quickpdf.org/forum/forum_posts.asp?TID=535&KW=C%2B%2B&PID=2335&title=visual-c-starter-example-code#2335

Here is the Debenu sample page for the first steps with the library:

Cheers and welcome here,
Ingo

Thanks for your help. This example is for use under Visual C++ but is not working on code blocks, so I can not make it run. Keep searching.

Cheers and thanks for the welcome.

Post a bit of code here which fails, and tell us what error reports or failure you are seeing. Does it fail to build, fail to run, or not give correct output? This is a users' forum so someone else here may be able to help (I am familiar with C++ but do not use it with QPDF). Saying just "doesn't work" gives no opportunity for anyone to suggest what you might try next!

Greets - resurrecting this a bit; I'm looking for a CPP reference script (instantiate class, unlock api) for QuickPDF; the VS scripts are not GNU CPP, so are not actually that useful to getting GNU CPP going.

The platform target is Debian 9, GCC 6.3 (preferably, but not mandatory) and the library from FoxitQPLLinuxCPP1711.

I have a non-working snippet as my baseline, drawn from various cobbled sources:

#include <iostream>
#include <string>
#include <cstring>
#include <sstream>
#include "Import/CPlusPlus/FoxitQPLLinuxCPP1711.h"
#include "Import/CPlusPlus/FoxitQPLLinuxCPP1711.cpp"

using namespace std;

int main()
{
wstring pdfkey = "12345";
wstring mymsg = "Loading result of key ";

FoxitQPLLinuxCPP1711 qp = new FoxitQPLLinuxCPP1711();
int result = qp.UnlockKey(pdfkey);

wcout << mymsg << pdfkey << " ---- " << result << endl;
return 0;
}

However, it is expecting, I believe, a specifically typed filename in the instantiation call based upon the errors:

testy.cpp:16:54: error: no matching function for call to ‘FoxitQPLLinuxCPP1711::FoxitQPLLinuxCPP1711()’

FoxitQPLLinuxCPP1711 qp = new FoxitQPLLinuxCPP1711();

class FoxitQPLLinuxCPP1711

I'm not a stellar cpp/c# programmer, but have a pretty good idea where the semi-colons go. I am currently writing code as baseline using 3 different pdf generation libraries, across both c++ and php, and this is the only library I have yet to get to work right out of the box.

A console-based reference script would be appreciated if available!

Thanks!

TH.
