ResetProgressProc

The file-based batch processing functions of the directory functions invoke a callback function based on the ResetProgressProc prototype to reset the user-defined progress display when a new stage of the batch operation has started.

Quick Info

BOOL (* ResetProgressProc)(
  LPVOID lpvAppDefined,  
  INT nMac               
);
 

Parameters

lpvAppDefined

Points to an application-defined parameter supplied in the CALLBACKPROGRESS structure member of the *_PARMS structure argument to the batch function.

nMac

Input parameter. The number of items to process, and the number of times to call the UpdateProgressProc function. If 0 (zero), which usually only occurs in the BatchExport or NWExport function, there are an unknown number of items to process.

Return Values

Return FALSE if the user cancels the operation; otherwise, return TRUE.

Remarks

If nMac is 0, the display shows only that n items have been processed, as opposed to showing the progress as a portion of the total processing to be performed.

For example, if nMac is 50, and the application displays a progress bar that is 500 pixels across, the display width could be broken into increments of 10 pixels, to have the display updated each time the UpdateProgressProc function is called.
