after Load you can check the document properties (author/creator).
If it's MS Word you can do a LoadFromFile and a new SaveToFile (and then it's QuickPDF and should work for you ;-)


Ahh that's a neat trick. I will definitely keep that in mind! Thanks!

I got it to work finally! And the problem is not in the Debenu Library. It's in the PDF I was trying to sign. 

Initially I'm trying to sign a temporary PDF file that was created by MS Word. I'm not sure what flags is MS-Word using but signing ANY PDF generated by MS Word ALWAYS fails. Very very frustrating!

I tried with another PDF file and it signed it perfectly, no problem at all.

Anyways. Thanks Ingo for the help.

Cheers!

Thanks Ingo! My next step after this is to add visual digital signature (which is also in the developer guide, very handy!). I will try this and see where this takes me.

Cheers!

I'm using Trial Version of QuickPDF v13.12, and I can't seem to get DPLSignFile to work. This is the barest minimum code that I made and I'm still stuck.

I'm using the code below:
Quote
DEBENUPDFLIBRARYLIB1312_DllMain(GetModuleHandle(NULL), DLL_PROCESS_ATTACH, NULL);
int InstanceID = DPLCreateLibrary();
auto retValue = DPLUnlockKey(InstanceID,L"my_unlock_key");

retValue = DPLSignFile(InstanceID, L"C:\\Users\\jmante\\Documents\\Unsigned.pdf",
L"",
L"DIGITAL_SIGNATURE",
L"C:\\Users\\jmante\\Documents\\Signed.PDF",
L"C:\\Users\\jmante\\Documents\\MyOwn.pfx",
L"123456789",
L"To test digital signatures",
L"The World",
L"Contact me");

DPLReleaseLibrary(InstanceID);
DEBENUPDFLIBRARYLIB1312_DllMain(GetModuleHandle(NULL), DLL_PROCESS_DETACH, NULL);
    return 0;
}


DPLSignFile always returns 1 but when I check the file using Acrobat DC it looks exactly as the unsigned version. There is also no Signature Tab/Panel. 

Thanks in advance.
