        }
        // Read Method 
        private string Read(string file)
        {
            StreamReader reader = new StreamReader(file);
            string data = reader.ReadToEnd();
            reader.Close();
            return data;
        }
        //Save Method
        private void Save(string file, string data)
        {

Kindly help me out.
Thanks & regards,

Hi,

To clairify is your question how to calculate how much time it will take to save the file, or how to use a progess bar with threading?

[marinus]

An easy way is to use

StreamReader reader = new StreamReader(file);
reader.BaseStream.Length; //reads the size of file and make calculation based on that

Im not sure but you can get reedTimeout with this

int x = reader.BaseStream.ReadTimeout;

Hope this helps.

Hi, Thanks for your reply.

i tried the in the save method itself

             private void Save(string file, string data)
        {
            StreamWriter writer = new StreamWriter(file);

            writer.Write(data);
            StreamReader reader = new StreamReader(file);
            long a = reader.BaseStream.Length;
            Console.WriteLine(a);

            writer.Close();

            this.progressBar1.Value = 0;
        }

it nt working..



Let me frame my question in a clear manner .

And my query is, Need to calculate how much percentage it will take to save the particular file. that particular percentage can be assigned to the value of the progress bar using threading.


For example, we can say to save a "abc.txt" file took 70% percentage means, then the progress bar has to show the loading to 70% with the help of threading.

Actually the task is,
"1.create a thread object in the button click event handler
2.create a delegate of parameterziedthreadStat as the entry point in the thread constructor.
3.Get the total length of the stream(file)
4.divide by 100
5.then assign that value to the progresssbar and need to show it.."

kindly help me out how to perform this five steps.. got struct.. since am new to winforms.. kindly help me out..

Priya
