Note: To be able to use the samples you must install novaPDF SDK
as samples work only with it. Download it here: nova PDF SDK.
The MFC Scribble sample extends the standard MFC Scribble sample with the generation of PDF files using novaPDF. It demonstrates how to integrate novaPDF SDK in a document/view MFC architecture:
Source Code Snippets 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 v6", L"<registration name>", L"<license key>");
m_pNova->Initialize(L"novaPDF Pro v6", 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;
}
