thank u so much for the reply rahul...How about the following ????????
Sorry i never mentioned that i have the number of bytes to be flashed known..

'WRITING THE DATA BYTES

progressbar.Max = number_records

For r = 0 To number_records

For b = 0 To bytes_per_record '

send record(r).byte(b)
recieve byte ' from target
check if recieved byte= sent byte ' byte level verification

Next b

check for checksum that is dependent on 16 bytes ' record level verification
progressbar.Value = progressbar.Value + 1 '

Next r

'VERIFYING THE DATA BYTES

progressbar.Max = number_records * bytes_per_record

For b = 0 To number_records * bytes_per_record
recieve byte ' from target
check if recieved byte= sent byte(b)
Next b
progressbar.Value = progressbar.Value + 1 '
***********************************************
I shall use one progress bar to perform my 'WRITE' and 'VERIFY' operations.
They wil be using the progress bar one after the other since it is a sequence process.
How far am I right ????
