I need to download a file from web i.e https:www.xxx.com using vb.net and save it to C drive of system.
Below is the code :
Dim URI As String = ftpHost & ftpFile
Dim oRequest As System.Net.HttpWebRequest = CType(HttpWebRequest.Create(URI), HttpWebRequest)
oRequest.Credentials = New System.Net.NetworkCredential(userName, pwd)
[code]....
But this is not reading anything.
I would like to download a file using VB.NET (preferably) or C# via HTTPS.
I have this code to download a file over plain HTTP:
Dim client As WebClient = New WebClient()
Dim wp As WebProxy = New WebProxy("[IP number of our proxy server]", [port number of our proxy server])
wp.Credentials = CredentialCache.DefaultCredentials
client.Proxy = wp
client.DownloadFile("http://sstatic.net/so/img/logo.png", "c:logo.png")
How do I change this code to download a file that is stored on an HTTPS-server? I guess it has something to do with adding credentials or something.
i used System.Net.Webclient to download a file from https address with username and password.I want to know if it is possible to get all file names from that https location, delete files,etc.

View 2 RepliesSo the exact site I'm trying to login to is GMail. I can send the POST data to login fine, but after that GMail performs an authentication (the redirect URL contains 'SetSID?'). Now with my HTTPWebRequest I don't see a way to enable support of HTTPs requests. Is there a way to get around this and successfully login?

I need to post a tab delimited file via the https post request. I need to be able to do this in asp.net VB. I have found various methods in C# however as I am still rather new to asp.net VB I certainly do not have the ability to translate the C# version. The link it posts to is password and username protected. I need to post the file in the message body. Below is an example request that it needs to produce: [Code]
View 1 RepliesWe have a site that is public facing, let's say it's [URL]. When the SSL is implemented, [URL], I can no longer access the jQuery 1.4.3 file on my own server. Furthermore, after a tweak to the security setting, I was able to get past the 'Access is Denied' error, but the first call was null. I understand there is a problem with different protocols actually being within the scope of the cross-domain problem? Is that true? And if so, will this now require JSONP?

I want to download thousands of files from the web and save them locally. What is the most efficient way? It is important the failures timeout within 10 seconds.
Is there a better way to stream one stream into another? Maybe a smaller buffer, like 1024 bytes at a time, is more efficient for large files?

View 6 RepliesI am writing a Windows Form program to automatically download and store generated PDF reports from a web site using the WebBrowser Control. The web site uses Ajax to link an icon back to the source aspx file which then returns a PDF file.
The problem I have is that the WebBrowser control brings up the File Save As dialog box when the PDF file is returned and I can find no way of handling this to cature and save the returned file. I have found other examples of how to manage this using the Navagating event to validate the extension of the file that is being accessed (e.g. [URL] and, if not an HTM, file then use the HTTP Web control to directly download the file. Unfortunately this will not work as the call references a .aspx page.

The Name of the file that the user is downloading The Url Were the file is being saved The Size of the file The speed at which the file is being downloaded And the Status.

View 12 RepliesI'm looking for a way to (easily, by preference ;)) create a download link to a file on a separate file server.The situation is as follows: the application I'm developing (asp.net 2.0 in vb.net but I have a similar issue in c#, either solution works for me) will be run internally for a company.As is good practice, the file storage and web application are on two separate servers.I basically need to be able to create a download link to a file, the only available URL i have to access the file is servernamefolder1folder2folder3file.txt (can be any sort of file)[code]Which doesn't work for obvious reasons. It used to be set up to write that file to the application path itself and that worked perfectly, but it isn't good practice and that's why I'm changing it (or trying to).I read solutions about creating a download page and then having a table in your DB which holds the links and returns the proper web URL for download but the time constraint I am faced with unfortunately doesn't allow me to develop that.
Assuming I can provide a string with the full filepath to the file like the above, what is the easiest way to just create a link that, when clicked, downloads the document? I have 0 admin rights in this environment. That really isn't helping me. Let's assume I am given the correct link like above and have the appropriate file access rights and such.The above example does work in IE, but not in Firefox and Chrome. IE converts it to a file://servername/... link which does what it's supposed to, but FF and Chrome both actively decided that this is unsafe and have disabled it from their browsers.

View 1 RepliesI want to create a HTTPS (Secure) Website. And how to create a Asp.net website using vb.net?
View 1 RepliesI'm creating an API for a particular website. This API will be in the form of a referable DLL. I've tried the normal HttpListner but it errors when getting any data that is through https (basically anything specific about the currently logged in user). I also can't log in using it. My next attempt involved a hidden webbrowser but that is just as hacked up as it sounds (and very glitchy seeing as the WebBrowser likes to interrupt processes that are currently running with its events). I need a system that works and is fast and efficient (I know, I know, kind of a oxymoron). Does anybody know how to do this?I'm using VB.net so any .net code examples are acceptable.
View 2 RepliesI have a very simple application that posts an XML file to a web service.
ohttp.open("POST", "https://target.web.site")ohttp.send(stringrequest)
Now this works on most workstations, the prompt for the private key is displayed the user presses OK and the XML is passed and a response is received. I have found some client computers that this does not work on. The computer does not display the prompt for the private key. I have been trying to figure out what is suppressing/blocking the prompt for the private key confirmation.
I am using the following code to try and redirect to https, it is not working.
If Not Request.IsLocal AndAlso Not Request.IsSecureConnection Then
Dim redirectUrl As String = Request.Url.ToString().Replace("http:", "https:")
Response.Redirect(redirectUrl)
End If

Working on a program that makes use of a third party API. That API can be found here:[URL]I'm a beginning/intermediate VB.Net developer, and have written other programs, but not using something like this.

The actual URL is internal to our network and I have that information of course.

Now first i would like to ask if i am going about this the right way ? the service i am communicating with is not .net but is built to handle large amounts of requests. I have obtained the following code that suggests it will do what i am after

Dim request As HttpWebRequest
' Create the request

The problem i have is if the above will work for me where exactly do i catch the returned xml string ? I assumed "result" would be the xml output string.
