3.3

Events

The IPXCPrinter interface provides events which can be used by a Developer's applications to

determine the stage of the PDF creation process. Some events are fired during document spooling

and these events are asynchronous to prevent dead-locking. Events which are fired during the

generation of PDF documents are synchronous.

An asynchronous event means that PDF-XChange fires the event and will not wait while application

receives this event and returns from it. It also means that the application will receive these events

immediately when they are fired.

PDF-XChange Driver API SDK

When a synchronous event is fired, PDF-XChange will wait until the application has finished this

event.

All events have a JobID parameter which specifies an internal Job identifier of the printed document.

This ID can be used when multiple documents are printing to determine from which document the

event was fired.

The following events are supported in PDF-XChange Driver v4.

·Asynchronous Events:

Event OnStartDoc is fired when a new document starts to print.

Event OnStartPage is fired for each page when it starts to print.

Event OnEndPage is fired for each page after it prints.

oEvent OnEndDoc is fired when the complete document is spooled by the GDI.

·Synchronous Events:

oEvent OnDocSpooled is fired immediately when PDF-XChange starts processing the document

that was printed by the GDI.

Event OnFileSaved is fired when the PDF file is saved.

Event OnFileSent is fired when emailing of the PDF file was enabled and after the email was

sent. If emailing is not enabled this event will not fire.

Event OnError is fired when an error occurs during the processing of the PDF file.

3.3.1

Asynchronous Events

The following Asynchronous events are supported in PDF-XChange Driver v4.

Event OnStartDoc is fired when a new document starts to print.

·Event OnStartPage is fired for each page when it starts to print.

·Event OnEndPage is fired for each page after it prints.

·Event OnEndDoc is fired when the complete document is spooled by the GDI.

Zero based page number spooled.

PDF-XChange Driver API SDK

Return value

PDF-XChange ignores returned values from this event.

3.3.1.4

Event OnEndDoc

This event is fired when the complete document has been spooled by the GDI.

Declaration:

event OnEndDoc(int JobID, int bOK);

C++

HRESULT OnEndDoc(LONG JobID, LONG bOK);

Event OnEndDoc(JobID As Long, bOK As Long)

JobID

Internal Job identifier.

bOK

When this parameter is True, the document has fully spooled and PDF-XChange will continue to

process this document to produce the PDF file. If there was an error during printing (e.g. printing

cancelled) there will be no further document processing.

Return value

PDF-XChange ignores returned values from this event.

3.3.2

Synchronous Events

The following Synchronous events are supported by the PDF-XChange V4 Driver.

·Event OnDocSpooled is fired immediately PDF-XChange starts processing the document printed by

the GDI.

·Event OnFileSaved is fired when the PDF file is saved.

·Event OnFileSent is fired when PDF emailing is enabled and after the email has been sent. If

emailing is not enabled this event will not fire.

·Event OnError is fired if an error occurs during the processing of the PDF file.

3.3.2.1
