Hi!

There is a Delphi-version (dcu), a dll and an activeX-version.

In your case i think dll or (better) activeX you should use.

How to use a dll in C++ Builder you'll know by your own.

All other stuff you'll find here:

Cheers and welcome here,

QPL works perfectly fine in BCB6.

Copy the QuickPDFDLL0725.cpp and .h file from the \QuickPDF\DLL\Import\CPlusPlus directory into you project directory. Also copy the QuickPDFDLL0725.DLL file to C:\WINDOWS\SYSTEM32 on 32bit or C:\Windows\SysWOW64 on 64 bit Windows or into the project directory where the compiled EXE file will reside.

// In your include section ...

#include "quickpdfdll0725.cpp" // Note this is the CPP file.

QuickPDFDLL0725 QP("quickpdfdll0725.dll"); // A global.

#include <string>

using namespace std;

__fastcall TForm1::TForm1(TComponent* Owner)

: TForm(Owner)

{

int InstanceID;

string s = "<put your key here>";

if (QP.UnlockKey(s) != 1)

MessageBox(Handle, "QPL License Key not valid", "Warning", MB_OK);

}

void __fastcall TForm1::Button1Click(TObject *Sender)

{

int ret = QP.LoadFromFile("Quick.pdf");

...

Enjoy,

Andrew

I didn't realise that you wanted to use the Lite version.

The Lite version only comes as an ActiveX control. So you will need modify the project to use the QuickPDFLite0725.cpp and .h files.

You will also need to make sure the Active DLL is registered in windows with regsvr32.

The constructor for QuickPDFList0725 does not need the DLL name as a parameter.

With these few small changes it should work correctly. Let us know if you cannot get it working.

It should be something like this

// In your include section ...

#include "QuickPDFLite0725.cpp" // Note this is the CPP file.

QuickPDFLite0725 QP; // A global.

#include <string>

using namespace std;

__fastcall TForm1::TForm1(TComponent* Owner)

: TForm(Owner)

{

int InstanceID;

string s = "<put your key here>";

if (QP.UnlockKey(s) != 1)

MessageBox(Handle, "QPL License Key not valid", "Warning", MB_OK);

}

void __fastcall TForm1::Button1Click(TObject *Sender)

{

int ret = QP.LoadFromFile("Quick.pdf");

...

I have tried those steps with version 9.14 with C++ Builder 6, but I get:

"Could not find a match for 'DebenuPDFLibraryDLL0914::DebenuPDFLibraryDLL0914(char *)'"

on the following line in my code:
DebenuPDFLibraryDLL0914 QP ("DebenuPDFLibraryDLL0914.dll");

From what I can tell by looking at the constructor, it needs a wstring type as a parameter. Not sure how to create a wstring.

Thanks

I finally figured this out on my own. Changing my code to this:
DebenuPDFLibraryDLL0914 QP (L"DebenuPDFLibraryDLL0914.dll");
worked (added 'L' before the string).

PS: The "Getting started" for DLLs that is installed with version 9.14 is incorrect. It still references an InstanceID and all the function names start with "DPL" which also seems incorrect.
