    <p>I'd like my application to query a csv file from a secure website. I have no experience with web programming so I'd appreciate detailed instructions. Currently I have the user login to the site, manually query the csv, and have my application load the file locally. I'd like to automate this by having the user enter his login information, authenticating him on the website, and querying the data. The application is written in C# .NET.</p> <p>I've tested the following code already and am able to access the file once the user has already authenticated himself and created a manual query.</p> <pre><code> System.Net.WebClient Client = new WebClient(); Stream strm = Client.OpenRead("https://&lt;URL&gt;/file.csv"); </code></pre> <p>Here is the request sent to the site for authentication. I've angle bracketed the real userid and password.</p> <pre><code>POST /pwdVal.asp HTTP/1.1 Accept: image/jpeg, application/x-ms-application, image/gif, application/xaml+xml, image/pjpeg, application/x-ms-xbap, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, application/x-shockwave-flash, */* User-Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; InfoPath.2; Tablet PC 2.0; OfficeLiveConnector.1.4; OfficeLivePatch.1.3; .NET4.0C; .NET4.0E) Content-Type: application/x-www-form-urlencoded Accept-Encoding: gzip, deflate Cookie: ASPSESSIONID&lt;unsure if this data contained password info so removed&gt;; ClientId=&lt;username&gt; Host: www3.emidas.com Content-Length: 36 Connection: Keep-Alive Cache-Control: no-cache Accept-Language: en-US client_id=&lt;username&gt;&amp;password=&lt;password&gt; </code></pre>

    1. COPlease provide some more information about how the user logs in. Are you using BASIC or DIGEST authentication? Is this some sort of cookie / login session login?

    2. CO@Broam I'll gladly submit any information but I'm unfamiliar with authentication protocol. If you'd tell me how to find out what type of authentication is used I'll post it below.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
