The MemoryDataTransferEventArgs type exposes the following members.

Properties

	Name	Description

	BytesPerRow	Gets the number of bytes per scan line in the data.
	BytesWritten	Get the number of bytes written to the Data pointer.
	Cancel	Gets or sets a value that indicates whether the scan should be canceled.

	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
