RE: WebClient and File Download

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

Hi,

Do you mean that directly calling
WebClient.DownloadFileAsync("http://www.sample.com/mydir/myfile.csv";,
"c:\1.csv") will fail with 404?

That's strange if the URL really exists. Please try if following code works
on your side:

Imports System.Net
Imports System.ComponentModel

Module Module1

Sub Main()
Dim wc As New WebClient()
AddHandler wc.DownloadFileCompleted, AddressOf
wc_DownloadFileCompleted
wc.DownloadFileAsync(New
Uri("http://msdn2.microsoft.com/default.aspx";), "c:\temp\1.txt")
Console.Read()
End Sub

Sub wc_DownloadFileCompleted(ByVal sender As Object, ByVal e As
AsyncCompletedEventArgs)
Console.WriteLine("Done")
End Sub

End Module

As you can see, the code is simple. If the URL exists and you're actually
able to download the root document, I don't see why it fails.
