Hi

I tried to use DLL Edition instead of LIB Edition then it works fine.
So I guess my pdfs are not protected.

The error I got in LIB Edition is 0xC0000005: Access violation.
I guess some of my setting in my IDE are incorrect but other function works well or ...

Hi :)

so some of your pdfs are protected?
How are the security settings?
Is there a master-password (not the user password)?
Try decrypt before signing...

Ingo,

Thank you for reply.
Unfortunately, the problem function terminate before returning value,
so I couldn't get the result of GetLastError().
If I set parameter pfxFileName to be empty or wrong paths,
the function ends properly and returns error value.

Hi Yuen,

what is function LastErrorCode telling you?
You should insert it directly after your problem function call.
If this doesn't give you any idea you should search here:
http://www.debenu.com/docs/pdf_library_reference/Search.php
with the tag "search".

Cheers and welcome here,
Ingo

Hi,
I'm trying to add digital signature on some pdfs but my program terminate in DPLSignFileA without warning.
I work with DebenuPDFLibraryLIB0916, MFC on Visual studio 2012.
I have no idea what is wrong.
Please help.

Here is what I did:

CString inputFileName = "C:\\Temp\\test.pdf";
    CString openPassword = "";
    CString signatureFieldName = "Signature1";
    CString outputFileName = "C:\\Temp\\Signed.pdf";
    CString pfxFileName = "C:\\Temp\\aaa.pfx";
    CString pfxPassword = "aaa";
    CString reason = "";
    CString location = "";
    CString contactInfo = "";

    CStringW strLicenseKey(LICENCEKEY_DEBENU_PDFLIB);
    int m_InstanceID = DPLCreateLibrary();
    int iResult = DPLUnlockKey(m_InstanceID, (WCHAR*)(LPCUWSTR)strLicenseKey);

    int ret = DPLSignFileA(m_InstanceID, (char*)(LPCTSTR)inputFileName,
                                        (char*)(LPCTSTR)openPassword,
                                        (char*)(LPCTSTR)signatureFieldName,
                                        (char*)(LPCTSTR)outputFileName,
                                        (char*)(LPCTSTR)pfxFileName,
                                        (char*)(LPCTSTR)pfxPassword,
                                        (char*)(LPCTSTR)reason,
                                        (char*)(LPCTSTR)location,
                                        (char*)(LPCTSTR)contactInfo);
