my target:
I want to upload a file via HTTP Post and show the user a
progress bar
my 1st try:
I´ve used WebClient.UploadFile and WebClient.UploadData,
they work fine but I don't know any way to get the actual
amount of transferred bytes, so what should I show on the
progressbar?
my next try:
Ok, I use WebClient.OpenWrite now (so i can transfer
little blocks and then show the progress), creating the
MIME-headers was not that hard and in my home-LAN
everything seems to work fine.
my problem:
When I transfer data to the internet the Write-method
returns to fast (although it should by synchronous), so I
send the next block and so on. When the progressbar nearly
reaches 100% (depending on file size), my program freezes
and on my Network data is still sent (OK, no wonder that
sending 2MB over 128kbs upstream doesn't happen in 5
seconds).
When the file is small enough, it reaches the website.
When it's too big I get an exception (some kind of buffer
overflow I guess).
my questions:
why does the write method return still sending data?
how can I get the Information if data was really sent?
Is there an asynchronous way to do it?
Thank you
regards
Sven
