in the vb program i pass in this url to download the file (include my password and username): [URL] but what has been downloaded to my C: is the login page(in myfile.txt) but when i use the url on the web browser[URL] i managed to get the file (the actual file).

I'm trying to use a java servlet in a 3rd party tool's web interface (CA service desk) to invoke it's download file functionality using a webclient in vb.net. The trouble is the text stream from response is markup and not the acutual text file stream.
It's like the page is redirecting to another page which actually presents the file for downloading. I have no idea what the redirected page URL is.
Is there a way I can process this redirected page in order to get at the download using a system.net.webclient?

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.

View 13 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 am trying to automate file downloads. Sometimes I get to a webpage that has a file link to download a file, but it is not a direct link. Instead it is a PHP request on the server side, for the file.
Is it possible to automate this using the webbrowser control, or is there another way I can do this using VB .NET?
I have an account with a website and I want my software to automatically download files that are generated.
I go to the website and login, and then I click a link that downloads a file. Unfortunately, I can't use the My.Computer.Network.DownloadFile function, because the first argument of that function is a file address (http:// www . website . html/file.txt). Instead of that, the address if I look at the link to download the file is something like this (http:// www . website . com/pid=1&output=csv&action=view&pview=pview).
You see how this won't work? I'm looking to use my software to automatically download the file that's available, but I can't use the DownloadFile function.
We are trying to find a way to download a file (PDF) that is attached as link to a web page. In our VBA application we were using URLDownloadtofile but that command has seemed to stop working and we think the company changed the proxy setup. We believe that the system needs a log in to work correctly, so we decided to try it in VB 2005. I was trying to find out if there is a way for me to use a similar command, and I am hoping that if I stay attached to the web browser active session that I'll be able to bypass the problem.another way to do it that would work in VBA that would be fine too. The benefit to the VBA is that all of the code is written unlink my VB 2005 app which is only partly done.
