I'm trying to sign PDF in C++ with latest TRAIL version (also tried with purchased 9.14) in VS 2013.

When calling function DPLEndSignProcessToFile I get Access violation executing location 0x0028A97A. Any idea what am I doing wrong?


int __cdecl main(int argc, char* argv[])
{
DEBENUPDFLIBRARYLIB1114_DllMain(GetModuleHandle(NULL), DLL_PROCESS_ATTACH, NULL);

  int InstanceID;
  InstanceID = DPLCreateLibrary(); 
  if (DPLUnlockKey(InstanceID, L"_license_key_") == 1) {

    auto res = -1;

    auto process_id = DPLNewSignProcessFromFile(InstanceID, L"test.pdf", L"");

    res = DPLSetSignProcessPFXFromFile(InstanceID, process_id, L"demo.pfx", L"password");

    res = DPLSetSignProcessInfo(InstanceID, process_id, L"To test digital signatures", L"The World", L"Contact me");

    res = DPLSetSignProcessField(InstanceID, process_id, L"Contract Signature");

    res = DPLEndSignProcessToFile(InstanceID, process_id, L"TheSignedFile.pdf"); 
    
    res = DPLGetSignProcessResult(InstanceID, process_id);

 }

  DPLReleaseLibrary(InstanceID);
  DEBENUPDFLIBRARYLIB1114_DllMain(GetModuleHandle(NULL), DLL_PROCESS_DETACH, NULL);
}//END main
