# Class ProgressMonitor

ProgressMonitor is an interface that an application can use to indicate the progress of a lengthy operation (such as PDFDoc.Save()).

ProgressMonitor has a range and a current position. The range represents the entire duration of the operation, and the current position represents the progress the application has made toward completing the operation.
