Save images to folder in VB.net

Question

I am trying to save an image from the client side to a folder using vb.net

"" the image that has the myImage ID ""

<asp:Image runat="server" ID="myImage" ImageUrl="http://www.govcomm.harris.com/images/1F-81-imageLinks650a.jpg" />
<asp:Image runat="server" ID="myImage2" ImageUrl="http://www.govcomm.harris.com/images/2F-81-imageLinks650b.jpg" />

this is just the location where i want to save my image : i haven't run or try any thing with this code , i am just wondering how to do this this location is on the server side

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
  Dim saveLocation As String = Server.MapPath("PDFs")
End Sub

Also, I would like to know if there is a way to use the id to save since i might have more than one image to be saved.

Answer 1

Try this one.....
import System.Net
Dim filepath As String = Server.MapPath(myImage.ImageUrl)

Using client As New WebClient()
client.DownloadFile(filepath, Server.MapPath("Specify the path where you want to    store+imagename"))       //------For  example  client.DownloadFile(filepath,Server.MapPath("~/Image/282.gif"))
End Using

Answer 2

If you want to upload a file from the client side (from the user via browser) to the server folder, you need to user the FileUpload control

<asp:FileUpload ID="FileUpload1" runat="server" />

And in your Codebehind, you can save that to a location by Calling the PostedFile.SaveAs method

    If FileUpload1.HasFile Then
        somefileNameWithExtension="file.pdf" ' Replace this with a a valid file name
        FileUpload1.PostedFile.SaveAs(somefileNameWithExtension)
    End If

EDIT : As per the comment

If you want to download a file from the internet, you can do it with the WebClient classes DownloadFile method. Here is an example.

    Using webClient As New WebClient()

        Dim targrtFileName = "D:\\myfile.png" ' 
        Dim sourceFile = "http://converter.telerik.com/App_Themes/images/ccHead.png"
        'read the Source of your image control and replace in sourceFile  variable.

        webClient.DownloadFile(sourceFile , targrtFileName)

    End Using
