i want to automatic file download using vb from an https site.i don't know the full file name. the file name is make up by 2 pieces, i only the 1st portion of filename.
View 2 RepliesI 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 1 RepliesI have a program that logs into a secure site, looks on the user's home page to find a list of links to reports that can be downloaded and then selects each one - this is currently a manual process but with 100 reports a time it takes a while. The idea is that all the reports will download to a specified folder with generic names so the user can play with them on their own computer rather than having to search through them online.
Anyway, everything's gone well as far as using a WebBrowser to connect to the site, log in and get the list of URLs however it falls down when it tries to link to them. I have tried two methods:
1 - Navigating straight to the URL, this gives an error message every time (asking me to try again)
2 - Directly downloading the URL with a WebRequest class (below) however this doesn't download the actual file, but rather a copy of the login page.
Current Code:
Public Sub DownFile(ByVal sFile As String, ByVal sRemoteUrl As String)
Dim wr As HttpWebRequest
Dim ws As HttpWebResponse

I am adding code to use a proxy server to access the Internet.The code works fine when requesting a file from a normal (HTTP) location, but does not work when accessing a secure location (HTTPS).[code]...
View 1 RepliesI have a https site where i have to display images from a http source. To enable this i want to make a proxy, so i can display the image as:
src="https://mydomain/showimage.aspx?url=http://externalserver/image.jpg"
I can do this in Java, somthing like this:
Code:
InputStream in = new WebInputStream( url );
BrowserOutStream out = new BrowserOutStream();
while(in.read()){ out.write() };
in.close();
out.close();
Simple enough (although the code is simplified here). But i cant seem to find a proper example of the equivalent in vb .net. I am assuming i have to use System.Net.WebClient.OpenRead, but not sure where to go from there.
I am not sure if this is possiable but I am looking to build an application that will login to a web site, navigate the site and download files. I would like to do this all in code and able to run multiple instances of the program to get information from many different web sites. Is something like this possiable in VB.net?
View 3 RepliesI'm deploying a VB.Net app (VS 2010 Pro) that requiers the user click a command button to open IE to a financial WEB site and download informaion from the site. The app works fine in every detail when installed on the development computer. But, on the target computer when the command button is clicked an unhandled exception occurs which says: System.IO. FileNotFoundException:File Not found.My code behind the button is Shell("C:Program Files (x86)Internet Exploreriexplore.exe www,fidelity.com",AppWinStyle.NormalFocus)
This works fine on the development computer. Do I need a way to code this as a relative path? If so,can you tell me how this is done?Throughout the app I have written relative paths to needed files using paths like (Open(Environment. GEtFolderPath (Environment. SpecialFoldder.Desktop) + "File Name). They all work fine when deployed.

I can read the file when I run the program, but how do I write the file path so that someone else can download my program and file and read the file on their system?

I am using Skybound's GeckoWebBrowser to access some site and it works fine with http. If I use a particular https site with certificate it gives error."This Connection is Untrusted".
This site is opening through Firefox after I added a certificate provided by the site in Servers tab.
But when I use GeckoWebBrowser to access this site it gives "This Connection is untrusted" error.
What do I do ? How do I make this site trusted programmatically or how do I add certificate programmatically to GeckWebBrowser.
We 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?

The code below creates multiple folders based on different file names and moves those files into the new folders. For example, files ABC and XYZ are moved into a newly created folder named ABC and XYZ. I want to advance the code to allow slightly different file names to go into a common folder. Example, I want file ABC_rock, ABC_soil, and ABC_water to be put into a folder named ABC still, AND file XYZ_rock, XYZ_soil, and XYZ_water to be put into a folder named XYZ. I do not want a separate folder created for ABC_rock, ABC_soil, and ABC_water.

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.

View 1 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.

I have a class that add extra information about a column for linq2sql (see code below) right now, I have to explicitly tell what column I want that info on, how would you put that code with a loop on every column in every table from a dbml file?
