webclient

[farshad]

Hi everyone.
My webclient code works fine for downloading a single file from a website.
But now I would like to download two or as many as there are files on the website. This gives an error as follows, although it still downloads the second file too.?:
The error is: An unhandled exception of type system.net.webexception occured in system.dll
Additional information: The remote server returned an error (404) not found

Thank you

What is your code? What lines is the error on?

This is the code.

Dim strURL As String = "http://www.test.com/images/"
Dim strFileName1 As String = "pic1.gif"
Dim strFileName2 As String = "pic2.JPG"
Dim strFullPath1 As String = Nothing
Dim strFullPath2 As String = Nothing
Dim wc As New WebClient

strFullPath1 = strURL + strFileName1
strFullPath2 = strURL + strFileName2

wc.DownloadFile(strFullPath1, strFileName1)
wc.DownloadFile(strFullPath2, strFileName2)

try this :

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim client(1) As Net.WebClient
        Dim strUrls() As String = {"http://www.computerhelp.forum/images/blue/on.gif", "http://www.computerhelp.forum/images/smilies/mad.gif"}
        Dim strPath() As String = {"D:\im1.gif", "D:\im2.gif"}
        Dim x As Integer

        For x = 0 To 1
            client(x) = New Net.WebClient()
            client(x).DownloadFile(strUrls(x), strPath(x))
            client(x).Dispose()
        Next

    End Sub

I tried your code, none of those two imaes exist on the server. Tried downloading and viewing in browser. Thats why the error. Maybe you should look for some other website with images for testing

download

With the help of someone on this site I have managed to download specific files from a web site and save them on the local machine.

But now I would like to loop through the folder in the website and one by one collectthe files and on each loop upload the files
Thanks


This bit of code downloads specific files from a website to the local machine
Dim strURL As String = "http://www.test.com/images/"
Dim strFileName() As String = {"image1.jpg", "image2.gif"}
Dim strFullPath As String
Dim wc(1) As WebClient

For i As Integer = 0 To 1

wc(i) = New WebClient
strFullPath = strURL & strFileName(i)
wc(i).DownloadFile(strFullPath, "C:\Farshad\Net\VB\Windows\" & strFileName(i))
wc(i).Dispose()
Next



This bit of code gets all the files in a folder on the local machine...

Dim d() As String

d = System.IO.Directory.GetFiles("C:\Farshad\Net\VB\Files\")

Dim en As System.Collections.IEnumerator

en = d.GetEnumerator

While en.MoveNext
Console.WriteLine(CStr(en.Current))
End While
