SetUploadStream Method
Sets the stream from which the component will read data to upload to the server.
Syntax
public void setUploadStream(java.io.InputStream uploadStream);
Remarks
If an upload stream is set before the Upload method is called, the content of the stream will be read by the component and uploaded to the server. The stream should be open and normally set to position 0. The component will automatically close this stream if CloseStreamAfterTransfer is true (default). If the stream is closed, you will need to call SetUploadStream again before calling Upload again. The content of the stream will be read from the current position all the way to the end and no bytes will be skipped.
Note: SetUploadStream and LocalFile will reset the other.
