Not for entire application or particular class.

CurrentUICulture and CurrentCulture are settable per thread as discussed here https://stackoverflow.com/questions/468791/setting-currentculture-and-currentuiculture-of-an-application. You can&#39;t change `InvariantCulture` at all.

Sample code to change cultures for current thread:

    CultureInfo ci = new CultureInfo(theCultureString);
    Thread.CurrentThread.CurrentCulture = ci;
    Thread.CurrentThread.CurrentUICulture = ci;

For class you can set/restore culture inside critical methods, but it would be significantly safe to use appropriate overrides for most formatting related methods that take culture as one of arguments:

    (3.3).ToString(new CultureInfo(&quot;fr-FR&quot;))

With 4.0, you will need to manage this yourself by setting the culture for each thread as Alexei describes. But with 4.5, you can define a culture for the appdomain and that is the preferred way to handle this. The relevant apis are [CultureInfo.DefaultThreadCurrentCulture][1] and [CultureInfo.DefaultThreadCurrentUICulture][2].

  [2]: http://msdn.microsoft.com/en-us/library/system.globalization.cultureinfo.defaultthreadcurrentuiculture.aspx

If you use a Language Resource file to set the labels in your application you need to set the its value:

    CultureInfo customCulture = new CultureInfo(&quot;en-US&quot;);
    Languages.Culture = customCulture;

I know that Activities can be declared in manifest as being excluded from recents with `android:excludeFromRecents`: 
http://developer.android.com/guide/topics/manifest/activity-element.html#exclude

However, that&#39;s not what I&#39;m looking for, I would like to know if there is a way to remove the app from recent apps **programmatically**

I have a fixed sidebar on the left of my site with content that has too much content to display on the screen. How can I make that content scrollable while still allowing the right side to be scrollable?

I would think that a simple `overflow-y: scroll;` would suffice. It seems like I need to have a max-height on the sidebar, but setting that max-height to 100% does nothing. I&#39;m sure this is a simple code pattern, but alas, my CSS skills have deserted me today.

I want to set default culture info for that class or for entire application.

For example in Turkey 3,2 = in english 3.2

so application uses my local but i want it to use as default 

    System.Globalization.CultureInfo.InvariantCulture


How can i set it to that as default for that specific class or for entire application

I&#39;m wondering how the `ConfigurationManager.AppSettings[Key]` works.

Does it read from the physical file each time I need a key? If so, should I be reading all the app settings of my web.config in a cache and then read from it?  

Or does ASP.NET or IIS load the web.config file only once at application startup?

How do I verify whether the physical file is accessed by each read? If I change the web.config, IIS restarts my application, so I can&#39;t verify it that way.

I&#39;m trying to wrap my head around which data structures are the most efficient and when / where to use which ones.

Now, it could be that I simply just don&#39;t understand the structures well enough, but how is an `ILookup(of key, ...)` different from a `Dictionary(of key, list(of ...))`?

Also where would I want to use an `ILookup` and where would it be more efficient in terms of program speed / memory / data accessing, etc?

I have a project that can build fine on my local machine, however, when I get TFS to build it, I receive the following error - 

SGEN: An attempt was made to load an assembly with an incorrect format: &lt;path to third part .dll&gt;

After reading through many other posts here on this topic, most people just say I need to change the build type to either x86 or Any CPU, rather than x64, but after trying countless combinations, this was not the solution. My program is also a windows service, so setting the App Pool to allow 32 bit applications (as suggested by others) is also not the solution.

I&#39;m declaring some strings that are empty, so it won&#39;t throw errors later on.

I&#39;ve read that this was the proper way:

    string Camnr = Klantnr = Ordernr = Bonnr = Volgnr = Omschrijving = Startdatum = Bonprioriteit = Matsoort = Dikte = Draaibaarheid = Draaiomschrijving = Orderleverdatum = Regeltaakkode = Gebruiksvoorkeur = Regelcamprog = Regeltijd = Orderrelease = &quot;&quot;;

But that doesn&#39;t work. I get this error: `Klantnr does not exist in the current context`.

What did I do wrong?

Declare and assign multiple string variables at the same time

I&#39;m using the ASP.NET WebApi to create a RESTful API.  I&#39;m creating a PUT method within one of my controllers, and the code looks like this:

	public HttpResponseMessage Put(int idAssessment, int idCaseStudy, string value) {
		var response = Request.CreateResponse();
		if (!response.Headers.Contains(&quot;Content-Type&quot;)) {
			response.Headers.Add(&quot;Content-Type&quot;, &quot;text/plain&quot;);
		}

		response.StatusCode = HttpStatusCode.OK;
		return response;
	}

When I PUT to that location with the browser via AJAX, it gives me this Exception:

&gt; Misused header name. Make sure request headers are used with
&gt; HttpRequestMessage, response headers with HttpResponseMessage, and
&gt; content headers with HttpContent objects.

But isn&#39;t `Content-Type` a perfectly valid header for a response?  Why am I getting this exception?

Can&#39;t set Content-Type header on HttpResponseMessage headers?

I&#39;m adding remote devices to a list as they announce themselves across the network. I only want to add the device to the list if it hasn&#39;t previously been added.  

The announcements are coming across an async socket listener so the code to add a device can be run on multiple threads.  I&#39;m not sure what I&#39;m doing wrong but no mater what I try I end up with duplications. Here is what I currently have.....

    lock (_remoteDevicesLock)
    {
        RemoteDevice rDevice = (from d in _remoteDevices
                                where d.UUID.Trim().Equals(notifyMessage.UUID.Trim(), StringComparison.OrdinalIgnoreCase)
                                select d).FirstOrDefault();
         if (rDevice != null)
         {
             //Update Device.....
         }
         else
         {
             //Create A New Remote Device
             rDevice = new RemoteDevice(notifyMessage.UUID);
             _remoteDevices.Add(rDevice);
         }
    }

I&#39;m wondering if there are any differences between `MemoryCache` and `HttpRuntime.Cache`, which one is preferred in ASP.NET MVC projects?

As far as I understand, both are thread safe, API is from first sight more or less the same, so is there any difference when to use which?

System.Runtime.Caching.MemoryCache vs HttpRuntime.Cache - are there any differences?

I am creating a simple wpf desktop application. UI have just a button and code in .cs file like.

    private void Button_Click_2(object sender, RoutedEventArgs e)
    {
        FunctionA();
    }

    public void FunctionA()
    {
        Task.Delay(5000).Start();
        MessageBox.Show(&quot;Waiting Complete&quot;);
    }

But surprisingly line `Task.Delay(5000).Start();` is throwing an `InvalidOperationException`: 

&gt;Start may not be called on a promise-style task. 

Can any one help why it is like this?

I am calling a webservice and the returned data for a bool field is either 0 or 1 however with my model I am using a System.Bool

With Json.Net is it possible to cast the 0/1 into a bool for my model?

Currently I am getting an error

&gt; Newtonsoft.Json.JsonSerializationException: Error converting value &quot;0&quot; to type &#39;System.Boolean&#39;


Any help would be awesome!!

Convert an int to bool with Json.Net

I&#39;m a member of a team with more than 20 developers. Each developer works on a separate module (something near 10 modules). In each module we might have at least 50 CRUD forms, which means that we currently have near 500 **add buttons**, **save buttons**, **edit buttons**, etc.

However, because we want to globalized our application, we need to be able to translate texts in our application. For example, everywhere, the word **add** should become **ajouter** for French users.

What we&#39;ve done till now, is that for each view in UI or Presentation Layer, we have a dictionary of key/value pairs of translations. Then while rendering the view, we translate required texts and strings using this dictionary. However, this approach, we&#39;ve come to have something near 500 **add** in 500 dictionaries. This means that we&#39;ve breached DRY principal.

On the other hand, if we centralize common strings, like putting **add** in one place, and ask developers to use it everywhere, we encounter the problem of not being sure if a string is already defined in the centralized dictionary or not.

One other options might be to have no translation dictionary and use online translation services like Google Translate, Bing Translator, etc.

Another problem that we&#39;ve encountered is that some developers under the stress of delivering the project on-time can&#39;t remember the **translation keys**. For example, for the text of the add button, a developer has used **add** while another developer has used **new**, etc.

What is the best practice, or most well-known method for globalization and localization of string resources of an application?

I have to detect decimal separator in current windows setting. Im using visual studio 2010, windows form. In particular, if DecimalSeparator is comma, if user input dot in textbox1,  I need show zero in textbox2.


I tryed with this code, but not works:

    private void tbxDaConvertire_KeyPress(object sender, KeyPressEventArgs e)
        {
            string uiSep = CultureInfo.CurrentUICulture.NumberFormat.NumberDecimalSeparator;
            if (uiSep.Equals(&quot;,&quot;))
            {
                while (e.KeyChar == (char)46)
                {
                    tbxConvertito.Text = &quot;0&quot;;
                }
            } 
        }

I have tryed also this code, but not work:

    private void tbxDaConvertire_KeyPress(object sender, KeyPressEventArgs e)
        {
            string uiSep = CultureInfo.CurrentCulture.NumberFormat.NumberDecimalSeparator;
            if (uiSep.Equals(&quot;,&quot;))
            {
                if (e.KeyChar == (char)46)
                {
                    tbxConvertito.Text = &quot;0&quot;;
                }
            } 
        }

Detect decimal separator

I&#39;m wondering if there is a concise and accurate way to pull out the number of decimal places in a decimal value (as an int) that will be safe to use across different culture info?

For example:  
19.0 should return 1,  
27.5999 should return 4,  
19.12 should return 2,  
etc.

I wrote a query that did a string split on a period to find decimal places:

    int priceDecimalPlaces = price.ToString().Split(&#39;.&#39;).Count() &gt; 1 
                      ? price.ToString().Split(&#39;.&#39;).ToList().ElementAt(1).Length 
                      : 0;

But it occurs to me that this will only work in regions that use the &#39;.&#39; as a decimal separator and is therefore very brittle across different systems.
