Using WebClient you can download your file synchronously as well as asynchronously.
Download File Synchronously
using System.Net;
WebClient webClient = new WebClient();
webClient.DownloadFile("http://mysite.com/myfile.txt", @"c:\myfile.txt");
Download File Asynchronously
private void btnDownload_Click(object sender, EventArgs e)
{
WebClient webClient = new WebClient();
webClient.DownloadFileCompleted += new AsyncCompletedEventHandler(Completed);
webClient.DownloadProgressChanged += new DownloadProgressChangedEventHandler(ProgressChanged);
webClient.DownloadFileAsync(new Uri("http://mysite.com/myfile.txt"), @"c:\myfile.txt");
}
private void ProgressChanged(object sender, DownloadProgressChangedEventArgs e)
{
progressBar.Value = e.ProgressPercentage;
}
private void Completed(object sender, AsyncCompletedEventArgs e)
{
MessageBox.Show("Download completed!");
}
Hope this will help!

Madam I think u didnt get my point.
For example, I call a function to download a file x to drive c:. In the middle of the operation, I close the downloading program. The program would abort the transfer, but not delete the partially downladed file x.
I start the program, and once again call the function to download the same file x to driver c:. The function would realize that there is already a part of file x present on drive c: and then resume the download.
Thanking You,
Sunil G.

The HttpWebRequest.AddRange()[^] method allows you to resume downloading from a specific point.

I would recommend using Socket Class which provides you to resume, stop your downloading or Uploading.

i would like to know how to add a mousehovr effec to lines in the richtext control
Bad = knowing 2 much
|
|
|
|
|
You can use the GetCharIndexFromPosition() method of the rich text box to get the index of the character nearest to the specified position and then use this index to create a tooltip for each line.
See here for an example on how to use GetCharIndexFromPosition().

I used the following code in a programming lesson to help me with a project but the lecturer says it is hard to maintain although I made it like that for better manageability:
static List<Person> _person = new List<Person>();
static void Main()
{
Dictionary<string, Action> methodList = new Dictionary<string, Action>();
methodList.Add("1", (() =>
_person.ForEach(s => Console.WriteLine("{0} {1}", s.Name, s.Title))));
_person.Add(new Person( "James","Prog" ));
_person.Add(new Person( "Claire","Illu"));
Console.WriteLine("Press 1 to show all data or 2 to quit");
string input = Console.ReadLine();
if (methodList.ContainsKey(input)) methodList[input]();
Console.Read();
}

Was he talking about the lamda stuff? If so, he's right. Rookie programmers would have a learning curve to go through. The lamda stuff doesn't give you anything in terms of speed, so it's rather pointless. If it doesn't improve the speed, obfuscated code like that is nothing more than a hindrance.
Of course, you'll find others here that disagree with me.

I can see your point however I disagree about lambda being a hindrance, the lambda expression in there is not complicated and saves me the hassle of having to make a method just to display the members which may only happen once. Although I can see that if I needed to display the details in other classes it would not be very productive.
Thanks for the reply !

We're talking about maintenance, not productivity. If you want better maintainability, you shouldn't use the lamda. Adding code complexity with no tangible performance gain is bad practice, IMHO.

A simpler anonymous method may suffice.

It gives you speed when compared to overrides.. a switch is much faster though (and in this case probably also clearer)
That doesn't mean I disagree, of course.
|
|
|
|

But we're not talking about overrides. We're talking about populating a dictionary from a list...

I know, but soon the "anti switch" guerrillas will find the thread and suggest "a beautiful OO solution"

Did your XML generics get swallowed?
What exactly is he concerned about?

Thanks for the replies so far!
I think my lecturer is assuming that the program that was shown could be "grown" so I did not use switch as I assumed if the system were to grow adding more switch statements would decrease its quality?
Is there a better way around this instead of encapsulating the routines into the dictionary?
|
|
|
|
|
More switches? Why not just add more cases to a big switch?
|
|
|
|
|
That is true I initially used switches but as the project has an "unknown" amount of lookups I thought the latter approach would suit it?
|
|
|
|
|
Perhaps you should have told us what the requirements were.
What would he say to a system of plug-ins? 
|
|
|
|
|
Where does that "unknown" come from? Unknown at compile time? (that would eliminate switch as option..)
