IContinueCallback::FContinuePrinting

Answers 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

This method supports the standard return value E_UNEXPECTED, as well as the following:

S_OK: Continue the printing operation.
S_FALSE: Cancel the print job as soon as possible.

Remarks

Implementations of IPrint::Print call 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. IPrint::Print can 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 in mid-page.
