MFC Scribble - SDK sample

1. Register novaPDF Printer event
#define PROFILE_NAME      L"MFCScribble Profile"
#define PDF_FILE_NAME     L"MFCScribble.pdf"
#define PROFILE_IS_PUBLIC 0 

// This message is sent when the PDF file is finished and saved on the harddisk
const UINT  wm_Nova_FileSaved = RegisterWindowMessageW( MSG_NOVAPDF2_FILESAVED );
BEGIN_MESSAGE_MAP(CScribbleView, CScrollView)
//{{AFX_MSG_MAP(CScribbleView)
//...
//}}AFX_MSG_MAP
//...
ON_REGISTERED_MESSAGE(wm_Nova_FileSaved, OnNovaPDFFileSaved)
END_MESSAGE_MAP()

2. Initialize INovaPDFOptions
CScribbleView::CScribbleView()
{
//...
HRESULT hr = CoInitialize(NULL);
//...
//create novaPDFOptions object
hr = CoCreateInstance(__uuidof(NovaPdfOptions), NULL, CLSCTX_INPROC_SERVER, __uuidof(INovaPdfOptions), (LPVOID*) &m_pNova);
//...
//initialize novaPDFOptions object with desired printer name
// if you have an application license for novaPDF SDK,
// pass both the registration name and the license key to the Initialize() function
// m_pNova->Initialize(L"novaPDF Pro v5", L"<registration name>", L"<license key>");
m_pNova->Initialize(L"novaPDF Pro v5", L"", L"", L"");
}

3. Release INovaPDFOptions 

CScribbleView::~CScribbleView()
{
//release novaPDFOptions object
if (m_pNova){
  m_pNova->Release();
}
CoUninitialize();
} 

4. Set novaPDF Printer Options
BOOL CScribbleView::OnPreparePrinting(CPrintInfo* pInfo)
{
//set novaPDF default printer
if (m_pNova){
  m_pNova->SetDefaultPrinter(); 

  // create a temporary profile for the current print job,
  // in order to not modify the default profile settings
  m_pNova->AddProfile(PROFILE_NAME, PROFILE_IS_PUBLIC);
  // set PDF document Title
  m_pNova->SetOptionString(NOVAPDF_INFO_TITLE, L"MFC Scribble Sample", PROFILE_NAME, PROFILE_IS_PUBLIC);
  // set resulting file name
  m_pNova->SetOptionString(NOVAPDF_SAVE_FOLDER, L"", PROFILE_NAME, PROFILE_IS_PUBLIC);
  m_pNova->SetOptionString(NOVAPDF_SAVE_FILE, PDF_FILE_NAME, PROFILE_NAME, PROFILE_IS_PUBLIC);
  //do not show prompt dialog
  m_pNova->SetOptionLong(NOVAPDF_SAVE_PROMPT, 0, PROFILE_NAME, PROFILE_IS_PUBLIC);
  //if file exists, override
  m_pNova->SetOptionLong(NOVAPDF_SAVE_CONFLICT_STRATEGY, FILE_CONFLICT_STRATEGY_OVERWRITE, PROFILE_NAME, PROFILE_IS_PUBLIC); 

  // set active profile
  m_pNova->GetActiveProfile(&m_wsDefaultProfile, &m_nActiveProfilePublic);
  m_pNova->SetActiveProfile(PROFILE_NAME, PROFILE_IS_PUBLIC); 

  //register window to receive messages from novaPDF printer
  m_pNova->RegisterEventWindow((LONG)m_hWnd);
}
//...
}

5. Restore options when printing finished
void CScribbleView::OnEndPrinting(CDC* /*pDC*/, CPrintInfo* /*pInfo*/)
{
if (m_pNova) {
  //unregister events
  m_pNova->UnRegisterEventWindow();
  //restore default profile
  m_pNova->SetActiveProfile(m_wsDefaultProfile, &m_nActiveProfilePublic);
  m_pNova->DeleteProfile(PROFILE_NAME, PROFILE_IS_PUBLIC);
  CoTaskMemFree(m_wsDefaultProfile);
  //restore default printer
  m_pNova->RestoreDefaultPrinter();
}
} 

6. novaPDF Printer message handler
LRESULT CScribbleView::OnNovaPDFFileSaved(WPARAM, LPARAM)
{
//PDF is saved, so just show a message that the conversion to PDF was successful
MessageBox(L"PDF file was saved successfully", L"novaPrint");
return 0;
}
