Syntax

Copy

public delegate void FileTransferEventHandler(
	Object sender,
	FileTransferEventArgs e
)

Public Delegate Sub FileTransferEventHandler ( 
	sender As Object,
	e As FileTransferEventArgs
)

Parameters

sender: Type: SystemObject
The Acquisition object which sent the event.
e: Type: Atalasoft.TwainFileTransferEventArgs

Remarks

You need to use QueryCapability(DeviceCapability.TransferMechanism) on the device to make sure it can handle File or File2 transfers. You should also use GetSupportedFileFormats to find out which SourceFileFormats the device supports.
