    <p>first time poster, long time reader, so take it easy on me :)</p> <p>I'm writing an application that reads in a bunch of folders and allows you to download an image for each folder. There is a WebBrowser control where you can browse to a particular image, and click a button "use this image for the selected folder".</p> <p>Each "folder" is represented as an object with its own download method, which uses WebClient inside a BackgroundWorker Thread.</p> <p>When I set the image url on the object, it starts the backgroundworker of that object and runs this code</p> <pre><code> using (WebClient client = new WebClient()) { client.Proxy = null; Stream stream = client.OpenRead(BackdropUrl); Bitmap bitmap = new Bitmap(stream); stream.Flush(); stream.Close(); e.Result = bitmap; } </code></pre> <p>I also use a webclient in my applications main thread to do some simple html "scraping".</p> <p>Now, to the problem. When I start using the app, all is good, the files will download as I go through the list, but after a while, it seems that the webclients randomly become unresponsive. I can still browse around in the webbrowser control, but all the webclient execution code seems to not complete it just hangs at one of these two lines:</p> <pre><code>Stream stream = client.OpenRead(BackdropUrl); Bitmap bitmap = new Bitmap(stream); </code></pre> <p>I know this is still pretty vague, but I tried to explain it as best I could. Does anyone maybe have a more robust way to download an image straight into a Bitmap object? i.e. not saving to file then opening it again?</p> <p>Any help will be greatly appreciated.</p>

    1. CODo you have the same issue if you use the same WebClient instead of creating a new one for each file ?

    2. COWell, i'm trying to keep each object "self contained"(dont know if thats the right phrase), so I don't now if there is a way to do this and only use one Webclient? I did a test at work quickly and it seemed to work without any problems, so I don't know if its maybe my internet connection at home that could cause this? Maybe I should try adding the items to a "download queue" and only allow two to download at a time?

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.
