You could use:

    myObject[propertyString] ;

    

There are two parts to this question:

1. Does _raising_ an event block the thread, or does it start execution of EventHandlers asynchronously and the thread goes continues on at the same time?

1. Are the _individual EventHandlers_ (subscribed to the event) run synchronously one after another, or are they run asynchronously with no guarantee that others aren&#39;t running at the same time?



Are C# events synchronous?

I have a small sqlitedb in my iOS device. When a user presses a button, I fetch the data from sqlite &amp; show it to user.

This fetching part I want to do it in a background thread (to not block the UI main thread). I do this like so - 

`[self performSelectorInBackground:@selector(getResultSetFromDB:) withObject:docids];`

After the fetching &amp; a little bit of processing, I need to update the UI. But since (as a good practice) we should not perform UI updation from background threads. I call a `selector` on mainthread like so - 

`[self performSelectorOnMainThread:@selector(showResults) withObject:nil waitUntilDone:NO];`

But my App crashes in the first step. i.e. starting a background thread. Is this not a way to start background threads in iOS? 

**UPDATE 1:** After `[self performSelectorInBackground....` I get this stacktrace, no info what so ever - 

![enter image description here][1]

**UPDATE 2:** I even tried, starting a background thread like so - 
`[NSThread detachNewThreadSelector:@selector(getResultSetFromDB:) toTarget:self withObject:docids];` but still I get same stacktrace.

Just so that I clarify, when I perform this operation on main thread everything runs smooth...

**UPDATE 3** This is the method I am trying to run from background 

    - (void)getResultSetFromDB:(NSMutableArray *)toProceessDocids
    {
        SpotMain *mirror = [[SpotMain alloc] init];
        NSMutableArray *filteredDocids = toProceessDocids;
    
        if(![gMediaBucket isEqualToString:@&quot;&quot;])
            filteredDocids = [mirror FetchDocIdsForMediaBucketWithDocID:filteredDocids mBucket:gMediaBucket numRes:-1];
        if(![gMediaType isEqualToString:@&quot;&quot;])
            filteredDocids = [mirror FetchDocIdsForMediaType:filteredDocids mediaType:gMediaType numRes:-1];
        if(![gPlatform isEqualToString:@&quot;&quot;])
            filteredDocids = [mirror FetchDocIdsForPlatformID:filteredDocids platformId:@&quot;1&quot; numRes:-1];
        
        self.resultSet = [mirror FetchObjectFromDocid:filteredDocids];
        [filteredDocids release];
        [mirror release];
    
        [self performSelectorOnMainThread:@selector(showResults) withObject:nil waitUntilDone:NO];
        return;
    }

I have a custom object:

    myObject.thing = anythingHere;


I would like to be able to retrieve a custom objects property by passing in a string... eg:

I can&#39;t quite figure that out. I&#39;ve looked at a number of tutorials for custom objects - but nothing shows how to get properties that I don&#39;t know the names of... Also - I would like to avoid looping through all properties if possible...

Here&#39;s the dilema, I have a webpage (only for android devices) and in that page I have an input box (a text box specifically) and when it gets focus the browser zooms in. I don&#39;t want it to zoom in - sounds easy, right?

Here&#39;s where it gets fun: I have to be able to zoom in general so don&#39;t say 

    &lt;meta name=&#39;viewport&#39; content=&#39;user-scalable=0&#39;&gt;
That won&#39;t work for me.

Also, the input box doesn&#39;t receive click events. It appears when another button is clicked a gets focus programmatically.

Here&#39;s what I&#39;ve tried and they&#39;ve failed so far:

    jQuery(&#39;head meta[name=viewport]&#39;).remove();
    jQuery(&#39;head&#39;).prepend(&#39;&lt;meta name=&quot;viewport&quot; content=&quot;width=720px;intial-scale=1.0;maximum-scale=1.0;user-scalable=no&quot; /&gt;&#39;);
    jQuery(&quot;#locationLock input&quot;).focus();
    jQuery(&#39;head meta[name=viewport]&#39;).remove();
    jQuery(&#39;head&#39;).prepend(&#39;&lt;meta name=&quot;viewport&quot; content=&quot;width=720px;intial-scale=1.0;maximum-scale=1.0;user-scalable=yes&quot; /&gt;&#39;);

This also failed:

    &lt;input type=&#39;text&#39; onfocus=&quot;return false&quot;&gt;

And this:

    jQuery(&quot;#locationLock input&quot;).focus(function(e){e.preventDefault();});

Any ideas?

I have this array:

    var arr = [];
    arr.push({name:&quot;k1&quot;, value:&quot;abc&quot;});
    arr.push({name:&quot;k2&quot;, value:&quot;hi&quot;});
    arr.push({name:&quot;k3&quot;, value:&quot;oa&quot;});

is it possible to do get the value or a specific element by knowing the name ?

something like this:

    arr[&#39;k2&#39;].value

or 

    arr.get(&#39;k1&#39;)

What is the difference between `window.location.href` and `window.open ()` methods in JavaScript?

window.location.href and window.open () methods in JavaScript

I remember there&#39;s a redirect function in jQuery.

It was like:

    $(location).href(&#39;http://address.com&#39;)

But what was it exactly? I couldn&#39;t remember and can&#39;t find it using Google Search.

I am using [this script][1] to make a style object of all the inherited, etc. styles.

    var style = css($(this));
    alert (style.width);
    alert (style.text-align);

With the following, the first alert will work fine, but the second one doesn&#39;t... it&#39;s interpreting the `-` as a minus I assume. The debugger says &#39;uncaught reference error&#39;. I can&#39;t put quotes around it, though, because it isn&#39;t a string. So how do I use this object property?

How do I reference a JavaScript object property with a hyphen in it?

I&#39;ve run into a unique situation that I have so far been unable to find a solution for: dynamically assigning a value to a CSS style.  I know how to use jQuery to assign width, height, etc. to an element, but what I&#39;m trying to do is actually change the value defined in the stylesheet so that the dynamically-created value can be assigned to multiple elements.  

What I&#39;m building is a slideshow of images that occupy the full viewport, recalculating the image&#39;s width, height, and left properties on resize so that the image is always centered, favors width over height, except when the viewport is taller than it is wide (resizing does not reload the page, just fires a function to resize the image).  

I have successfully been able to get it to work on one image, and now I&#39;m trying to determine the best way to assign those property values to all images in the slideshow without having to specify those three things individually for every image.  

My Question:
------------

Can the values of properties in a class be modified on the fly?  I&#39;m sure the answer is out there, I&#39;m probably just not using the correct terminology in my searches.  Hope I did a good job of describing the problem.  TIA.

Modifying CSS class property values on the fly with JavaScript / jQuery

I have seen two ways of detecting whether a UA implements a specific JS property: `if(object.property)` and `if(&#39;property&#39; in object)`.

I would like to hear opinions on which is better, and most importantly, why. Is one unequivocally better than the other? Are there more than just these two ways to do object property detection? Please cover browser support, pitfalls, execution speed, and such like, rather than aesthetics.

When I write code like this

    [XmlIgnore]
    [NonSerialized]
    public List&lt;string&gt; paramFiles { get; set; }

I get the following error:

    Attribute &#39;NonSerialized&#39; is not valid on this declaration type.
    It is only valid on &#39;field&#39; declarations.

&lt;br&gt;
If I write

    [field: NonSerialized]

I get the following warning

    &#39;field&#39; is not a valid attribute location for this declaration.
    Valid attribute locations for this declaration are &#39;property&#39;.
    All attributes in this block will be ignored.

&lt;br&gt;
If I write

    [property: NonSerialized]

I get the following error (again):

    Attribute &#39;NonSerialized&#39; is not valid on this declaration type.
    It is only valid on &#39;field&#39; declarations.

&lt;br&gt;
How can I use `[NonSerialized]` on a property?

I need to identify elements from which events are fired. 

Using `event.target` gets the respective element.

What properties can I use from there?


- href  
- id   
- nodeName


I cannot find a whole lot of info on it, even on the [jQuery][1] pages, so here is to hoping someone can complete the above list.


**EDIT:**

These may be helpful: [selfHTML node properties][2] and [selfHTML HTML properties][3]

What properties can I use with event.target?

I have a ArrayList with custom objects. I want to search inside this ArrayList for Strings.

The class for the objects look like this:

    public class Datapoint implements Serializable {
      
      private String stateBased;
      private String name;
      private String priority;
      private String mainNumber;
      private String groupadress;
      private String dptID;
    
      public Datapoint(){
      }
    
      public String getMainNumber() {
        return mainNumber;
      }
    
      public void setMainNumber(String mainNumber) {
        this.mainNumber = mainNumber;
      }
    
      public String getName() {
        return name;
      }
       
      ..and so on

I know how to search for a string in a ArrayList&lt;String&gt; but how to do that in a ArrayList with my custom objects:

    ArrayList&lt;String&gt; searchList = new ArrayList&lt;String&gt;();
    String search = &quot;a&quot;;
    int searchListLength = searchList.size();
    for (int i = 0; i &lt; searchListLength; i++) {
    if (searchList.get(i).contains(search)) {
    //Do whatever you want here
    }
    }


So I want to have a function to search in my ArrayList with for example five objects for all &quot;name&quot; strings.
