Process Event
Summary
Represents a process event.
Syntax
public:
event EventHandler<ProgressEventArgs^>^ Process
def Process(sender,e): # sender: BankCheckReader e: ProgressEventArgs
Event Data
The event handler receives an argument of type ProgressEventArgs containing data related to this event. The following ProgressEventArgs properties provide information specific to this event.
| Property |
Description |
| Cancel | Gets or sets the Cancel flag. When set to true cancels the process. |
| CurrentField |
The current field that is being processed. |
| FieldType |
The current BankCheckField type that will be or has been processed. |
| Percentage |
The current percent completion for processing the bank check image. |
| State |
The current state for the bank check image processing . |
