progress bar update?

[Techno]

Hi there.
I would like to know exactly how to go about creating a progress bar showing the "transfer" complete progress?

Basically, my app connects to an FTP and downloads a file. Objects are created locally to identify what the file is, if its a directory, what the size is of the file and so on...

I know I have to create a thread for the progress bar to avoid the UI from "hanging".

I pretty much have a progress bar on the form, and have made a method/thread to "Do" the progress bar update.

The thread gets created/called when the file it about to be downloaded.

But now what? How do I make the progress bar show almost "truely" or in sync or whatever, how much of the file has been downloaded?

do I set the maximum property of the progress bar to the size of the file to be downloaded?

then what?

What is your code for downloading like? Is it something that updates at regular intervals, or a thread that is started and nothing happens until the file is finished?

don't worry about the code when downloading... i dont really think that has any "integration" with the progress well it may do only when writing to a stream.....

im using .NET 2.0

im just using an FTP Request to download the file, it is then reading it and writing it to a BinaryReader/Writer stream

Well i hope someone can help

I pretty much did it my way - whilst it is reading the buffer, it writes to file and sets the step value to the buffer count.

cool, all works

now trying to find a way of finding the % so I can display that to the user, either using the progress value's properties (which will have the maximum value > 100) or some other calc...

Take a look at the two links I posted in this thread to see if they help you.

unfortunatly not I already had a look

code:

byte[] buffer = new byte[2048];
                int count = theBinReader.Read(buffer, 0, buffer.Length);



                this.SetStepProgValue(count);
                this.DoStepProgValue();

                while (count != 0)
                {
                    theBinWriter.Write(buffer, 0, count);
                    count = theBinReader.Read(buffer, 0, buffer.Length);


                    this.SetStepProgValue(count);
                    this.DoStepProgValue();
                }

done!

calculate_percent = count * 100 / theFileSize

where count = the stream reader read
