How do I handle print events PDF-XChange Drivers API SDK event handling and ATL?
Question:
How do I handle PDF-XChange Drivers API SDK print events?
Can you tell me how to handle print events, such as OnStartDoc, OnStartPage and so on.
I tried this way:
-Implement _IPXCPrinterEvents interface
-Ask IConnectionPointContainer at PXCComLib::IPXCControlEx object
-Make Advise
-Send document on print through application
-Wait for events
I use ATL.
Answer:
Here is a small example of a class declaration (or you can use an existing class) using ATL.
First add the following code to your stdafx.h:
#import "progid:PXCComLib.CPXCControlEx" rename_namespace("PXC"), named_guids
Second declare a class like this:
public:
MyPXCHandler()
{
m_pFactory = NULL;
m_pPrinter = NULL;
}
~MyPXCHandler()
{
Finish();
}
public:
HRESULT Prepare()
{
if (m_pPrinter != NULL)
return S_OK;
if (m_pFactory == NULL)
{
m_pFactory = PXC::IPXCControlExPtr(__uuidof(PXC::CPXCControlEx));
if (m_pFactory == NULL)
{
// handle error here
return E_FAIL;
}
}
m_pPrinter = m_pFactory->Printer[L"", L"PDF-XChange 4.0 Sample", L"<YOUR REG KEY HERE>", L"<YOUR DEV CODE HERE>"];
if (m_pPrinter == NULL)
return E_FAILE;
return DispEventAdvise(m_pPrinter);
}
HRESULT Finish()
{
if (m_pPrinter != NULL)
{
m_pPrinter->RestoreDefaultPrinter();
DispEventUnadvise(m_pPrinter);
m_pPrinter.Release();
}
if (m_pFactory != NULL)
{
m_pFactory.Release();
}
}
