I am looking to start an activity in my app using a custom action. I have found a few answers but everything I try it throws `java.lang.RuntimeException` saying No Activity found to handle Intent { act=com.example.foo.bar.YOUR_ACTION }.

This is the activity in my manifest file:

    &lt;activity
        android:name=&quot;.FeedbackActivity&quot; &gt;	
        &lt;intent-filter&gt;
            &lt;action android:name=&quot;com.example.foo.bar.YOUR_ACTION&quot; /&gt;
       	&lt;/intent-filter&gt;
    &lt;/activity&gt;

And this is how I&#39;m starting the activity:

    Intent intent = new Intent(&quot;com.example.foo.bar.YOUR_ACTION&quot;);
    startActivity(intent);

Any help would be greatly appreciated.

Okay, so I&#39;m developing an Android app that utilises a ViewPager to display pages.

Within each page, I have a set of buttons to use for navigating between pages (in addition to the swiping between pages). These buttons are for &quot;first page&quot;, &quot;previous page&quot;, &quot;next page&quot; and &quot;last page&quot;.

What I can&#39;t figure out how to do is engineer a mechanism to enable a page change on a button click.

Anyone have any ideas?

ETA: To better explain the setup, the buttons are declared within each page&#39;s layout, and are inflated with the rest of the layout within the PagerAdapter. My problem is that I can&#39;t reference the ViewPager from within the PagerAdapter. Or at least, I can&#39;t think of a way to do it.

I have the following piece of config in my App.config file:

    &lt;add key=&quot;ConnectionString&quot; 
         value=&quot;INITIAL CATALOG=myDatabase;DATA SOURCE=myServer;User ID=myUser;Password=!&amp;myPass99;&quot;/&gt;

The above connection string is rejected by Visual Studio intellisense. It says entity `myPass99` not defined. The problem is caused by the &amp; in the password. 

How do I escape it?

I have some number of generic lists in my code, that have tens or hundreds elements.
Sometimes I need to refill this lists with other objects, so question is: what will be faster, to call `Clear()` method or creating a `new List&lt;T&gt;()`?

Which is faster: clear collection or instantiate new

Hi why  `using (var sw = new StreamWriter(ms))` returns `Cannot access a closed Stream` `exception`. `Memory Stream` is on top of this code. 


    using (var ms = new MemoryStream())
    {
        using (var sw = new StreamWriter(ms))
        {                 
            sw.WriteLine(&quot;data&quot;);
            sw.WriteLine(&quot;data 2&quot;);
            ms.Position = 0;
            using (var sr = new StreamReader(ms))
            {
                Console.WriteLine(sr.ReadToEnd());                        
            }
        } //error here
    }

What the best way to fix it ?
Thanks

So I have a web project, and I&#39;m trying to get the root directory of the website using the c# method `Directory.GetCurrentDirectory()`.  I don&#39;t want to be using a static path as the file locations will be changing in the future.  This method is running in my imageProcess.aspx.cs file, but where I thought it would return:

    C:\Users\tcbl\documents\visual studio 2010\Projects\ModelMonitoring\ModelMonitoring\imageProcess.aspx.cs

I&#39;m instead getting:
    
    C:\Program Files\Common Files\Microsoft Shared\DevServer\10.0\

Can anyone explain why this is happening and what a possible solution might be? Thanks a lot.

I want to store words in a dictionary in following way:

I can get word code by word: `dict[&quot;SomeWord&quot;]` -&gt; `123` and get word by word code: `dict[123]` -&gt; `&quot;SomeWord&quot;`

Is it real? Of course one way to do it is two dictionaries: `Dictionary&lt;string,int&gt;` and `Dictionary&lt;int,string&gt;` but is there another way?

Since upgrading to RC for WebAPI I&#39;m having some real odd issue when calling POST on my WebAPI.
I&#39;ve even gone back to the basic version generated on new project. So:

    public void Post(string value)
    {
    }

and calling from Fiddler:

    Header:
    User-Agent: Fiddler
    Host: localhost:60725
    Content-Type: application/json
    Content-Length: 29
    
    Body:
    {
    	&quot;value&quot;: &quot;test&quot;
    }

When I debug, the string &quot;value&quot; is never being assigned to. It&#39;s just always NULL.
Anyone having this issue?

(I first saw the issue with a more complex type)

The problem is not only bound to ASP.NET MVC 4, the same problem occurs for a fresh ASP.NET MVC 3 project after RC installation

The Amazon Elastic Beanstalk blurb says:

&gt; Elastic Beanstalk lets you &quot;open the hood&quot; and retain full control  ...  even pass environment variables through the Elastic Beanstalk console.

I know this may looks like a previously asked question but I&#39;m facing a different problem here.

I have a utility class that has only static methods. I don&#39;t and I won&#39;t take an instance from it.

    public class Utils{
    	private static Properties dataBaseAttr;
    	public static void methodA(){
    	
    	}
    	
    	public static void methodB(){
    	
    	}
    }

Now I need Spring to fill dataBaseAttr with database attributes Properties.Spring config is:

&lt;!-- language: xml --&gt;

    &lt;?xml version=&quot;1.0&quot; encoding=&quot;UTF-8&quot;?&gt;
    &lt;beans xmlns=&quot;http://www.springframework.org/schema/beans&quot;
    	xmlns:xsi=&quot;http://www.w3.org/2001/XMLSchema-instance&quot; xmlns:util=&quot;http://www.springframework.org/schema/util&quot;
    	xsi:schemaLocation=&quot;http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
    	http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.0.xsd&quot;&gt;
    	
    &lt;util:properties id=&quot;dataBaseAttr&quot;
    		location=&quot;file:#{classPathVariable.path}/dataBaseAttr.properties&quot; /&gt;
    &lt;/beans&gt;

I already done it in other beans but the problem here in this class (Utils) isn&#39;t a bean, And if I make it a bean nothing changes I still can&#39;t use the variable since the class will not be instantiated and variable always equals null.

I am having trouble encrypting a connection string in app.config.  I have code that will protect the connectionStrings section of app.config, but the password is still displayed in plain text.

I need to encrypt the connection string in so it is not in plain text when deployed.  I see similiar questions on SO for web.config, but not app.config.

I used the second solution of
[https://stackoverflow.com/questions/179927/how-to-resolve-could-not-find-schema-information-for-the-element-attribute-xxx][1]

I.e. created a XSD with the button to create a scheme. I changed the stylesheet in app.config to app.xsd but now I get the warning:

   The Global element &#39;configuration&#39; has already been declared in app.xsd

Even when changing the name the warning is shown.
Does anybody have a solution for this?

I&#39;m doing some work in Visual Studio 2012 Express Edition. I have added an App.config XML file as follows:

    &lt;?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot; ?&gt;
    &lt;configuration&gt;
    &lt;/configuration&gt;

The first thing that happens is a warning comes up that says &quot;The &#39;configuration&#39; element is not declared&quot;. Does anyone know why this is happening? It looks like elements can not be declared inside of &lt;configuration&gt; until this is resolved.

Thanks!
