c# proxy
Is it possible to detect which proxy is active which is dead? using c# and a combo box containing list of proxies with port number is there any way we take every proxy one by one and determine as if it was dead or active?Microsoft.Win32.RegistryKey registry = Microsoft.Win32.Registry.CurrentUser.OpenSubKey(“Software\\Microsoft\\Windows\\CurrentVersion\\Internet Settings”, true);registry.SetValue(“ProxyEnable”, 1);registry.SetValue(“ProxyServer”, comboBox1.Text);

c# asp.net winforms using-statement
I’m trying to use the System.Drawing.Color namespace. I’m not able to define it at the top of the class:However, I can reference it within the class. That is, I can use this line of code, and it works:txtBox.BackColor = System.Drawing.Color.LightPink;… but I’d rather just be able to do this:txtBox.BackColor = Color.LightPink;If it’s a matter of a missing reference/dll, why am I able to make reference to System.Drawing.Color in my code?

c# .net dynamic .net-4.0 generic-type-argument
I suspect the short answer to this question is “no” but I’m interested in the ability to detect the use of the dynamic keyword at runtime in C# 4.0, specifically as a generic type parameter for a method.To give some background, we have a RestClient class in a library shared among a number of our projects which takes a type parameter to specify a type that should be used when de-serializing the response, e.g.:public IRestResponse<TResource> Get<TResource>(Uri uri, IDictionary<strin

This is an in-depth continuation of my question from earlier this morning, which I’m still stumped about. I’m using a strongly typed DataContext for my application and although it emits a warning, it magically works. How does it do this?Here’s the code one would typically use to connect to a database using LINQ-to-SQL.class MyDatabase : DataContext {public Table<Widget> Widgets;public Table<Car> Cars;public MyDatabase (string connection) : base(connection) { } }Even though it emits

c# datetime
For our support software in C#, I need to determine the time span between two DateTimes, but I only want opening hours counted (i.e. weekdays from 09:00 to 17:00).So, for instance, if the first DateTime is 15/02/2011 16:00 and the second is 16/02/2011 10:00, the method shall return 2 hours.Any help is greatly appreciated!

c# web-services exception-handling webmethod
I have a set of web services generated using the [WebMethod] attribute. Is it considered “good practice” to throw ArgumentException from such a method if its arguments aren’t properly specified (and no sensible defaults could be used)? If so, should this exception be caught and re-thrown in order to log it both on the server and the client?

c# winforms repaint
I’ve come across a problem that I’m hoping one of you fine thinkers can overcome…For some reason, once I have loaded up my Windows Form, if the user presses the ALT key, the form redraws causing a flash.This only happens the first time, so any subsequent presses of the ALT key do nothing.I don’t have any menu strips or events that handle the key press, so I can only assume it’s either a setting I haven’t set, or one that I have unknowingly set.FYI, the form does the following in the constructo

azure amazon-ec2 azure-web-roles restart azure-vm-role
I am currently using Azure PaaS worker/web roles and I am hitting an annoying issue where if my database role is working really hard (100% CPU) it gets automatically restarted by the Azure App Fabric controller. This is getting really frustrating.My options are to over provision the role and pay more to stop the restarts. OR seek a alternative service provider which doesn’t do auto / heartbeat / restarts.Are the IaaS VM instances also subject to a Heartbeat health check? What about Amazon’s EC2

c azure blob local hidden
AzureXplorer – local blob storage – unexpected hidden fies when manually creating foldersOur C# ListBlobs method that works OK up in Azure revealed one extra file per folder locally named “$$$.$$$” that are not visible in AzureXplorer or ClumsyLeaf. Neither Google nor MSDN has turned up any note of this so I was wondering if any one else has seen this. The workaround for this defect in AzureXplorer is to manually create local blob folders with ClumsyLeaf which does NOT produce these hidden fil

azure reliability azure-worker-roles
I want to create a web service hosted in Windows Azure. The clients will upload files for processing, the cloud will process those files, produce resulting files, the client will download them.I guess I’ll use web roles for handling HTTP requests and worker roles for actual processing and something like Azure Queue or Azure Table Storage for tracking requests. Let’s pretend it’ll be Azure Table Storage – one “request” record per user uploaded file.A major design problem is processing a single fi

It may seem large, but we’re a printers so many people do need to provide images of that size.The line of code that fails is:ImageResizer.ImageBuilder.Current.Build(Server.MapPath(strImagePath), Server.MapPath(strThumbPath), new ResizeSettings(“maxheight=” + “150”+ “&maxwidth=” + “238”));This is probably the GDI itself failing, but is t

We had ImageResizer through the below error and subsequently I believe the app pool crashed and a new one started… This, in turn, also caused a massive queue of images to build up and the service was down for half an hour. Anyone seen this before?Note, we’ve also seen a few “access denied” errors from ImageResizer in the EventLog for images with “images” in their filename. Unsure if related.Any thoughts would be much appreciatedException information: Exception type: ImageProcessingException Ex
