ProgressEventArgs Class

Summary

Reports the progress for specific BankCheckReader operations and offers the user an opportunity to cancel them.

Syntax

C++/CLI

Python

public class ProgressEventArgs : EventArgs

public ref class ProgressEventArgs : public System.EventArgs

class ProgressEventArgs(EventArgs):

Remarks

The ProgressEventArgs event is fired when processing a bank check, and returns the currently recognized field. For each recognized field a Processed event will be fired.

ProgressEventArgs event allows the user to cancel Process operation using the Cancel property
