Download an XML file with VB.Net from an external ASP website

External website has XML files available for download. The website provides manual download of the XML files from mouse clicks. We require a VB.Net module that automates this download. The module should contain a function that saves the XML file to a drive loacation. ## Deliverables The function should download the XML from the section obtained by selecting "Congestion Management, clicking Operational, then Cross border Commercial Schedules, then selecting country Germany. Finally under download it is the XML daily data file. Function downloadetso(dt As Date, sDir As String) As String ...... End Function Example Input date: 2008-Nov-17 (a date variable) Example directory: C:\\temp Example URL of XML file: [login to view URL] Functionality: [login to view URL] saved in location C:\\temp Output: success or failure message The VB.Net module should not rely on a browser or external software. The module may import standard namespaces such as [login to view URL] The module must run under Visual Studio 2008 version 9.0 under .Net framework 3.5. We will accept code that can execute within Visual Studio 2008 the above example and with any input date where there is an associated file. The external website returns the XML file as a result of an ASP postback. The above URL should provide enough infomation to work out the postback variables. All other infomation about the site must be gained from looking at their site and it's displayed source. * * *This broadcast message was sent to all bidders on Friday Nov 28, 2008 3:42:38 AM: Dear Coders, I have had good dialogue with a couple of bidders and as a result would like to bring your attention to some details that have arisen. 1. The website appears to automatically redirect some scripts to the defualt page resulting in the downloading of the html and not of the targetted xml file. 2. The function you write should create and destroy it's own session and be capable of repeated use. 3. The website uses username and password authentification. I would be interested in proceeding with a bidder who has overcome a similar problem of 1. before. Please review your bidding accordingly. Kind regards Daniel
