Hi everyone,

I need your help.

I'm writing a Vb.Net application which should copy many images (images001.jpg, images002.jpg...) from an URL address (i.e http://mysite.com/images/images001.jpg).

I don't know how to copy each image from the URL address (i.e http://mysite.com/images/) to a network path (i.e \\MyNetwork\Images\).

I had already found on internet a code which allow me to check the existence of any image giving a URL address.

Can anyone tell me how to copy an image from a URL to a specific path ?

Thank you.

Paul


    Function ImageExiste(ByVal p_url As String) As Boolean

        Dim xmlHttp
        xmlHttp = CreateObject("Microsoft.xmlHttp")
        xmlHttp.Open("GET", p_url, False)
        xmlHttp.Send()

        Select Case xmlHttp.status

            Case 200 'found
                ImageExiste = True

            Case 404 'Not found
                ImageExiste = False

            Case Else 'Some other problem
                ImageExiste = False

        End Select

        'ImageExiste = xmlHttp.Status
        xmlHttp = Nothing

    End Function

You should be able to expand this sample to allow you to download multiple files.

This downloads the file specified by srcPath to outPath.

The imports:

    Imports System
    Imports System.Net


The sub:

    Sub getFile()

        'Address of URL
        Dim srcPath As String = <URL to Your Image>
        Dim outPath As String = <Name to Save Image As>

        Dim client As WebClient = New WebClient

        client.DownloadFile(srcPath, outPath)

    End Sub

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

paulnamroud here's another way wrapped up in a proc:

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        GetImage("http://mysite.com/fs_img/mysite/0506/logo.gif", "C:\Logo.gif")
    End Sub

    Private Sub GetImage(ByVal URL As String, ByVal SaveAs As String)
        Try
            Dim srv_request As System.Net.WebRequest = System.Net.WebRequest.Create(URL)
            Dim srv_response As System.Net.WebResponse = srv_request.GetResponse()
            Dim ImgStream As IO.Stream

            ImgStream = srv_response.GetResponseStream()
            System.Drawing.Image.FromStream(ImgStream).Save(SaveAs)
        Catch
        End Try
    End Sub

I think the points should be split between myself and dave_moats.

I think Kinger's suggestion is valid as both solutions can be used to answer the question.
