Please read and help me, it code is short, no long, I need a help I'm nearing to send it for my teacher, I hope everyone will help me.
How you are transferring.... Tell me the which topic you are using Client --> Server, Remoting , Web Service ? if you are more clear then its easy to help you out
Thank verymuch for instruction, I have replace and change some variable int to long as you guide but it get two error here, please repaired it for me.

Lines 155 $ 156 use Convert.ToInt32
Hi a fix it as below.
private void OnUpdatepgdstatus(long s, long p)
{
progressbar.Maximum = Convert.ToInt32(s);
progressbar.Value = Convert.ToInt32(p);
}
So when I choose fie *iso about 2.5G it still fail ? if i replace to ToInt64 it not appropriate
Try using Convert.ToUInt32. Being unsigned you'll get a maximum of about 4 GB.
Oh I have try what you say, If used Convert.ToUInt32 or Convert.ToInt64 it get error here:

Ok I think I've got it now. Since the progress bar will only accept int anything over 2 GB will be too large. To accommodate larger files make the progressbar.maximum a fraction of the total size, maybe 1 tenth. Then do the PerformStep 10 times for every one your were doing before(i.e. If you were doing the PerformStep every 1,000 bytes do it every 10,000 bytes).
