Download from web [RESOLVED]

HI all,

I have a webpath say: www.webserver.com/getfile.asp

How to download the resulting htm file thru vb.net?

in vb6 i used to do the following:

VB Code:

Declare Function URLDownloadToFile Lib "urlmon" Alias "URLDownloadToFileA" (ByVal pCaller As Long, ByVal szURL As String, ByVal szFileName As String, ByVal dwReserved As Long, ByVal lpfnCB As Long) As Long
 
    Public Function DownloadFile(ByVal URL As String, ByVal LocalFilename As String) As Boolean
        Dim lngRetVal As Long
        lngRetVal = URLDownloadToFile(0, URL, LocalFilename, 0, 0)
        If lngRetVal = 0 Then DownloadFile = True
    End Function

pls guide

VB Code:

Dim myClient As New System.Net.WebClient
myClient.DownloadFile("http://www.google.com","C:\mydump.txt")

Good enough?

I tried that. But it gives me following error:

'The underlying connection was closed: The remote name could not be resolved.'

:confused: :confused:

If I copy and paste the same URL in IE then the page is opened without any error.

Well, I don't know exactly what you wanted out of the function, here's the same thing kind of with error-catching, and intretval will return 0 if the resource was not found, resulting in a false return from the function.

VB Code:

Public Function DownloadFile(ByVal URL As String, ByVal LocalFileName As String) As Boolean
 
        Dim myClient As New System.Net.WebClient
        Dim result As Boolean = False
        Dim S As System.IO.FileStream
        Dim myBuffer As Byte()
        Try
            myBuffer = myClient.DownloadData(URL)
            S = New IO.FileStream(LocalFileName, IO.FileMode.OpenOrCreate)
            S.Write(myBuffer, 0, myBuffer.Length)
            S.Flush()
        Catch
 
        Finally
            If Not S Is Nothing Then S.Close()
            myClient.Dispose()
 
        End Try
        If Not myBuffer Is Nothing Then result = True
        Return result
    End Function

If that works for you, please append resolved to your message title.

The stuff is working fine. But it takes lots of time to download.
