Hello,
I am trying to download web data into my current application. Failing
many attempts I tried to run the sample from the MS Help files with no
luck. If I create a new solution and put the sample code on a button
then it works. However, when do the same on a new form in my existing
solution then I get following error. Could there be some global
settings in my application that are causing problems?
Thanks in advance,
-Dave
Error:
-----------------------------------------------
An unhandled exception of type 'System.Net.Web Exception' occurred in
system.dll
Additional information: An exception occurred during a WebClient
request.
Sample Code:
-----------------------------------------------
Dim remoteUrl As String = "http://www.msn.com"
' Create a new WebClient instance.
Dim myWebClient As New System.Net.WebC lient
' Download the home page data.
Console.WriteLi ne(("Downloadin g " + remoteUrl))
' Downloads the Web resource and saves it into a data buffer.
' !!!!!!!!!! THIS LINE CAUSES THE ERROR !!!!!!!!!!!!!!!
Dim myDatabuffer As Byte() = myWebClient.Dow nloadData(remot eUrl)
' Display the downloaded data.
Dim download As String =
System.Text.Enc oding.ASCII.Get String(myDatabu ffer)
Console.WriteLi ne(download)
Console.WriteLi ne("Download successful.") 6 4380
Dave,
I think that for most of us that is impossible to see without the code that
generates the error.

Cor,
Please see my original post. The code is under the Sample Code heading.

Sorry, I had not seen it, however as you told this does work in a single
module, so where do you place it in your application?

I set up a form in a *new* application with one button and included the
code from my first post. When I click the button it returns the website
code as it should.
Next, I opened my existing (MDI) solution and added the form to the
root. I set the form as the start object (tried calling the form from
the mdi app as well) and ran the application. When I click the button I
receive the error message when the download is attempted.

I tried this
\\\
Private Sub Form1_Load(ByVa l sender As Object, _
ByVal e As System.EventArg s) Handles MyBase.Load
Me.IsMdiContain er = True
Dim frm2 As New Form2
frm2.MdiParent = Me
frm2.Show()
End Sub
///
And in Form2 in the button event the download code,
That works perfect

After further research I found a setting in the app.config. The
impersonate property was set to true. When I deleted this tag,
everything started to work.
I don't understand why that would cause a problem. Any ideas?

------APP.CONFIG FILE causes the errors--------
<?xml version="1.0" encoding="utf-8" ?>

Why does WebClient.DownloadFile loose my completed path?
Ok, I have a function in my app then when my button is clicked it checks to

For some reason I can't get a WebClient to access an outside URL from
behind our firewall. The code works when it runs outside the firewall.
I turned on windows authentication in the web.config
<authentication mode="Windows" />
and set up IIS to not allow anonymous access.
My browser is set up to auto detect the proxy server, so IE/Firefox can
access outside pages, so I added code to auto-detect the proxy server.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows.
