Answer whether a given lengthy printing operation should continue.
HRESULT FContinuePrinting(
LONG
cPagesPrinted, // Total pages printed at time of call
LONG nCurrentPage, // Number of page currently being printed
LPOLESTR pszPrintStatus // Pointer to status message about print job
);
Parameters
cPagesPrinted
The total number of pages that have been printed at the time the object receives a call to IContinueCallback::FContinuePrinting.
nCurrentPage
The page number of the page being printed at the time the object receives a call to IContinueCallback::FContinuePrinting.
pszPrintStatus
Pointer to message about the current status of the print job. The object being printed may or may not display this message to the user. May be NULL.
Return Values
S_OK
Continue the printing operation.
S_FALSE
Cancel the print job as soon as possible.
E_UNEXPECTED
An unknown error occurred.
Remarks
Implementations of IPrint call back on this method at periodic intervals during the printing process. The IPrint implementation should call back at least after printing each page, so that its client can, if necessary, display useful visual feedback to the user. Your Iprint implementation can legally call back multiple times with the same cPagesPrinted and nCurrentPage values, which is sometimes useful when a page being printed is complex and it is appropriate to give a user an opportunity to cancel mid-page.
