     textBlock.Foreground = new SolidColorBrush(Colors.White);

Foreground needs a Brush, so you can use

    textBlock.Foreground = Brushes.Navy;

If you want to use the color from **RGB** or **ARGB** then

    textBlock.Foreground = new System.Windows.Media.SolidColorBrush(System.Windows.Media.Color.FromArgb(100, 255, 125, 35)); 

or 

    textBlock.Foreground = new System.Windows.Media.SolidColorBrush(Colors.Navy); 

To get the Color from **Hex**

    textBlock.Foreground = new System.Windows.Media.SolidColorBrush((Color)ColorConverter.ConvertFromString(&quot;#FFDFD991&quot;)); 


You could use [`Brushes.White`](http://msdn.microsoft.com/en-us/library/system.windows.media.brushes.white.aspx) to set the foreground.

    myTextBlock.Foreground = Brushes.White;

The [`Brushes`](http://msdn.microsoft.com/en-us/library/system.windows.media.brushes.aspx) class is located in [`System.Windows.Media`](http://msdn.microsoft.com/en-us/library/system.windows.media.aspx) namespace.

Or, you can press &lt;kbd&gt;Ctrl&lt;/kbd&gt;+&lt;kbd&gt;.&lt;/kbd&gt; while the cursor is on the unknown class name to automatically add `using` directive.

To get the Color from Hex.

    using System.Windows.Media;
    
    Color color = (Color)ColorConverter.ConvertFromString(&quot;#FFDFD991&quot;);

and then set the foreground

    textBlock.Foreground = new System.Windows.Media.SolidColorBrush(color); 

I&#39;ve recently started learning to use the D3.js framework and, while it seems like it&#39;s been designed to do exactly what I want, I can&#39;t find a simple example of a &quot;live&quot; updating graph.

I&#39;m looking for something like a line chart that updates as new data becomes available. New data would be obtained either by hitting a json url with a &quot;last seen&quot; timestamp or some other AJAX-y method.

_edit:_ The D3 part of the answer is here:

http://bost.ocks.org/mike/path/

Now, how do people recommend getting the new data from the server to the client?

**Question one (formatting telephone number):**

I&#39;m having to format a telephone number in AngularJS but there is no filter for it. Is there a way to use filter or currency to format 10 digits to `(555) 555-5255`? and still preserve the data type of the field as integer?

**Question two (masking credit card number):**

I have a credit card field that is mapped to AngularJS, like:

    &lt;input type=&quot;text&quot; ng-model=&quot;customer.creditCardNumber&quot;&gt; 

which is returning the whole number (`4111111111111111`). I will like to mask it with xxx the first 12 digits and only show the last 4. I was thinking on using filter: limit for this but am not clear as how. Any ideas? Is there a way to also format the number with dashes but still retain the data type as integer? sort of `4111-1111-1111-1111`.

I was wondering if anyone knows a quicker way to find a table in the EDMX model than just scrolling through the diagram and looking for the thing. Our database has around 50 tables in it and when I&#39;m looking for a specific one it&#39;s just a chore to see where VS put the thing.

I&#39;m using VS 2010 for the purpose of this question.

Thank you in advance. 

How do I find a specific table in my EDMX model quickly?

After asking [this question][1], I am wondering if it is possible to wait for an event to be fired, and then get the event data and return part of it. Sort of like this:

    private event MyEventHandler event;
    public string ReadLine(){ return event.waitForValue().Message; }
    ...
    event(&quot;My String&quot;);
    ...elsewhere...
    var resp = ReadLine();
    
Please make sure whatever solution you provide returns the value directly rather than getting it from something else. I&#39;m asking if the method above is available in some way. I know about Auto/ManuelResetEvent, but I don&#39;t know that they return the value directly like I did above. 

**Update:** I declared an event using `MyEventHandler` (which contains a `Message` field). I have a method in another thread called `ReadLine` waiting for the event to fire. When the event fires the WaitForValue method (part of the event handling scene) returns the event args, which contains the message. The message is then returned by ReadLine to whatever had called it. 

[The accepted answer][2] to [that question][1] I asked was what I did, but it just doesn&#39;t feel quite right. It almost feels like something could happen to the data between the ManuelResetEvent firing and the program retrieving the data and returning it.

**Update:** The main problem with the `Auto/ManualResetEvent` is that it is too vulnerable. A thread could wait for the event, and then not give enough time for anyone else to get it before changing it to something else. Is there a way to use locks or something else? Maybe using get and set statements.

Why won&#39;t `Environment.GetEnvironmentVariable(&quot;variableName&quot;)` get a variable&#39;s value if the call is made from within a webMethod hosted on IIS and it will work if I call it from a console application on the same machine?

Where do I set up those variables to be visible to IIS web services? Should I use the second parameter from `Environment.GetEnvironmentVariable(name, target)` to get it?

It is actually really simple:

    [WebMethod(Description = &quot;Gets the environment variable value.&quot;)]
    public string GetEnvironmentVariable()
    {
        return Environment.GetEnvironmentVariable(&quot;VARIABLE_NAME_HERE&quot;);
    }

And by the way, VARIABLE_NAME_HERE is set at the system and user level.

My route is correctly configured, and my methods have the decorated tag.  I still get &quot;The requested resource does not support HTTP method &#39;GET&#39;&quot; message?

    [System.Web.Mvc.AcceptVerbs(&quot;GET&quot;, &quot;POST&quot;)]
    [System.Web.Mvc.HttpGet]
    public string Auth(string username, string password)
    {
      // D&#233;coder les param&#232;tres re&#231;ue.
      string decodedUsername = username.DecodeFromBase64();
      string decodedPassword = password.DecodeFromBase64();
                
      return &quot;value&quot;;
    }

Here are my routes:

    config.Routes.MapHttpRoute(
    	name: &quot;AuthentificateRoute&quot;,
    	routeTemplate: &quot;api/game/authentificate;{username};{password}&quot;,
    	defaults: new { controller = &quot;Game&quot;,
    					action = &quot;Auth&quot;, 
    					username = RouteParameter.Optional,

I have a list of tasks, which i&#39;d like to wait for. I&#39;m waiting like 

        await TaskEx.WhenAll(MyViewModel.GetListOfTasks().ToArray());

MyViewModel.GetListOfTasks() returns List of Task:

        var tasksList = new List&lt;Task&gt;();
        foreach (var item in Items)
        {                
            tasksList.Add(item.MyTask());
        }

Now, i&#39;d like to return dummy task, which would be done immediately. However, TaskEx.WhenAll would wait it forever:

        public Task&lt;bool&gt; MyTask()
        {
            return new Task&lt;bool&gt;(() =&gt; false);
        }

How can i return Task, which would be finished instantly?

I have got [this][1] HttpClient from Nuget.

When I want to get data I do it this way:

    var response = await httpClient.GetAsync(url);
    var data = await response.Content.ReadAsStringAsync();

But the problem is that I don&#39;t know how to post data?
I have to send a post request and send these values inside it: `comment=&quot;hello world&quot;` and `questionId = 1`. these can be a class&#39;s properties, I don&#39;t know.

**Update** I don&#39;t know how to add those values to `HttpContent` as post method needs it. `httClient.Post(string, HttpContent);`

I&#39;m teaching a jr. high/high school web programming class, and we&#39;re starting with simple elements and attributes like font and color before moving on to CSS. I know color is deprecated and font is not included in HTML5, but for teaching purposes, I find it convenient to start with simple HTML tags and work our way up to CSS. The students get a lot of joy out of being able to change colors on a page during the first week of class. (I also teach them marquee and blink in week 1, but inform them that if they ever use them again, they will lose points). 

One of the students started submitting homework with odd things in the color attribute values, like &quot;Skittles&quot; or &quot;Spiderman&quot;. I started experimenting with this and discovered that just about anything you put into the color=&quot;&quot; attribute on the font tag produces some sort of color. And it appears that the color is consistent across the latest versions of IE, Firefox, Chrome, Opera, and Safari.

I have discovered that putting &quot;LuckyCharms&quot; in as a CSS color DOES NOT WORK. It only seems to work where colors are expected in HTML attributes, for example font color=&quot;LuckyCharms&quot;, or body bgcolor=&quot;LuckyCharms&quot;.

I&#39;m trying to explain to my class why this happens, and so far I haven&#39;t been able to make sense of it, or to Google a good answer. It would appear that it&#39;s being interpreted as a color code, but I can&#39;t make sense of how.

***UPDATE:*** After some trial and error, I have determined a 5-step algorithm (using the link provided) to convert pretty much any string into the corresponding hex color. I will provide the algorithm here for the edification of future visitors:

 1. Change each non-hex character to a 0.
 2. Add 0&#39;s to the string until its length is a multiple of 3.
 3. Divide string into 3 equal parts.
 4. While the length of the sub-strings is greater than 2, and all three of the sub-strings begin with a 0, remove the leading 0s from each string.
 5. If the length of the sub-strings is still greater than 2, then truncate each substring to 2 characters.

That&#39;s it, put the substrings together and you&#39;ve got your hex color code. I have verified this algorithm with about 20 different samples and compared the results using the Firefox ColorZilla add-on color picker.

Note that in this case, the rules ARE indeed specifically stated in the link specified in one of the answers and will be adhered to by all browsers. So it is something you can count on to work in any browser (should you really want to use funny color names).

Why do weird things in font color attribute produce real colors?

I have a bunch of SVG images that I want to embed in an HTML page, which is styled with CSS.

I need help in taking right decision. I need to animate a background color of my user control when some event happens. When it is, I want to change the background just for 1 second and then turn it back. Which way should I go? Use color animation or timer or may by some other way.


Solved. Thanks to all! This works good for me:

            ColorAnimation animation;
            animation = new ColorAnimation();
            animation.From = Colors.Orange;
            animation.To = Colors.Gray;
            animation.Duration = new Duration(TimeSpan.FromSeconds(1));
            this.elGrid.Background.BeginAnimation(SolidColorBrush.ColorProperty, animation);

I have to wrap my icon within an `&lt;a&gt;` tag for some reason.  
Is there any possible way to change the color of a font-awesome icon to black?  
or is it impossible as long as it wrapped within an `&lt;a&gt;` tag? Font awesome is supposed to be font not image, right?
