progress bar issue...

Question

Hi,

I am uploading files in windows application using web services. I am having progress bar which

shows which file is uploading right now.

Is there a way that I can show this many bytes has been transferd till now and this many

percentage of data has been transfered.

I am keeping the file data in an byte array and this is one of the parameter to web service.

How can I detect this many bytes has been transferd till now.

Plz provide with sum suggesstion...

thank you....
