Hi, I'm quite sorry because at the time I wrote comment I was not being able to upload data for a long time because I did't see that there was a mistake in my code. Now I am already being able to upload data to server. By the way, I would like to know if there is a way for uploading data to server keeping session alive or do I have to open-send-close connection every time I need to upload records. Thank you very much in advance and apologize for the inconvenience. Regards. Emilio Rubio.
