<pre><code>"http://user:[email protected]/p/status.html"
</code></pre>
<p>this works fine once here I can pull the html and get the value.</p>
<p>My problem is I am trying to do the same thing but this time pull an image from the webite like so</p>
<pre><code>picturebox.Load("http://username:[email protected]/images/pic.jpg");
</code></pre>
<p>This returns an unauthorized error.</p>
<p>I also tried displaying the picture in a browser using </p>
<pre><code>webbrowser.url(uri(http://username:[email protected]/images/pic.jpg");
</code></pre>
<p>this works fine. However this is a camera feed so I would have to refresh the page each time which pages it go white and is not what I want.</p>
<p>Is there a way to accomplish this? preferably loading the picturebox with the url and getting the image in the picturebox.</p>
<p>Thanks,</p>

1,028,616 | 1,028,617 | LRU byte Cache java | <p>I need to implement a cache in java with a maximum size, would like to do it using the real size of the cache in the memory and not the number of elements in the cache. This cache will basically have String as key and String as value. I have already implemented the cache using the LinkedHashMap structure of java but the question is how to know the actual size of the cache so that i can adapt the policy to drop an object when the size is too big.</p>
<p>Wanted to compute it using the getObjectSize() of the instrumentation package but it seems not working as desired.</p>
<p>When I do getObjectSize( a string ) whatever the size of the string is, it returns the same size : 32. I guess it's just using the reference size of the string or something like that and not the content. So don't know how to solve this problem efficiently. </p>
<p>Do you have any ideas ? </p>

<pre><code>jQuery.fn.clearFields = function ( clearField ) {
var clearfield_search = "#"+clearField+"_search";
var clearfield_link = "#"+clearField+"_link";
var clearfield_search_label = "label[for='"+clearField+"_search']";

//removal of inital break & labels
$(clearfield_search_label).prev('br').remove();
$(clearfield_search_label).remove();
$(clearfield_link_label).prev('br').remove();
$(clearfield_link_label).remove();
//Removal of fields
$(clearfield_link).remove();
$(clearfield_search).remove();
}
alert("Removed");
}

<p>But my dilemma is I can't see to make explicit (multiple calls) to this function - - such as </p>
<pre><code>jQuery.fn.clearFields("ebsco");
jQuery.fn.clearfields("summon");
</code></pre>
<p>it seems only the first function call is executed - then nothing else happens - very frustrating.</p>
<p>Do I have to implement the calls using a for loop or the .each method - or I'm guessing there's something more fundamental I'm missing - or there is perhaps an even better cleaner way of doing this ?</p>
<p>Again any feedback much appreciated</p>

4,357,324 | 4,357,325 | Is there a Python module for transparently working with a file-like object as a buffer? | <p>I'm working on a pure Python parser, where the input data may range in size from kilobytes to gigabytes. Is there a module that wraps a file-like object and abstracts explicit .open()/.seek()/.read()/.close() calls into a simple buffer-like object? You might think of this as the inverse of StringIO. I expect it might look something like:</p>
<pre><code>with FileLikeObjectBackedBuffer(urllib.urlopen("http://www.google.com")) as buf:
header = buf[0:0x10]
footer = buf[-0x10:]

2,604,767 | 2,604,768 | iPhone:Tabbar hides when pushing from TableView to UIViewController | <p>I have four Tab bar items in a Tab bar which is being bottom of the view where i have the TableView. I am adding Tab bar and items programmatically (Refer below code) not through I.B.
Click on first three Tab bar items, will show the data in the same TableView itself. But clicking on last Tab bar items will push to another UIViewcontroller and show the data there. The problem here is, when i push to the viewController when clicking on last Tab bar item, main "Tab bar" is getting removed.</p>
<p>Tab bar code:</p>
<pre><code>UITabBar *tabBar = [[UITabBar alloc] initWithFrame:CGRectMake(0, 376, 320, 44)];
item1 = [[UITabBarItem alloc] initWithTitle:@"First Tab" image:[UIImage imageNamed:@"first.png"] tag:0];
item2 = [[UITabBarItem alloc] initWithTitle:@"Second Tab" image:[UIImage imageNamed:@"second.png"] tag:1];
item3 = [[UITabBarItem alloc] initWithTitle:@"Third Tab" image:[UIImage imageNamed:@"third.png"] tag:2];
item4 = [[UITabBarItem alloc] initWithTitle:@"Fourth Tab" image:[UIImage imageNamed:@"fourth.png"] tag:3];
item5 = [[UITabBarItem alloc] initWithTitle:@"Fifth Tab" image:[UIImage imageNamed:@"fifth.png"] tag:4];
NSArray *items = [NSArray arrayWithObjects: item1,item2,item3,item4, item5, nil];
[tabBar setItems:items animated:NO];
[tabBar setSelectedItem:item1];
tabBar.delegate=self;
[self.view addSubview:tabBar];
</code></pre>
<p>Push controller code clicking from last Tab bar item:</p>
<pre><code>myViewController = [ [MyViewController alloc] initWithNibName:@"MyView" bundle:nil];
myViewController.hidesBottomBarWhenPushed=NO;
[[self navigationController] pushViewController:myViewController animated:NO];
</code></pre>
<p>I am not seeing bottom Tab bar when i push my current TableView to myViewController. I am seeing full screen view there. I want to see bottom Tab bar always when every tab item clicked.
What might be the problem here? Could someone who come across this issue, please share your suggestion to me?</p>

<pre><code>var length = result.length -1;

To sumarize it, after installing my App, when I instantly start it, it is started from a different "root" than when I start it from the home screen. The effect is that when I press the home button after starting it and then want to return to the running activity the app is started again (because it was started from a different context). On this link there is also a solution proposed, but I don`t like it so much. So what I wanted to ask at last is, does this effect appear also to users who are downloading my app from the market? Because if, then I would be really suprised, because till it happened to me I didnt read about it at all and I also didnt hear that somebody has got this problem.</p>

The problem arises if someone is on say <a href="http://mysite.com/#page2" rel="nofollow">http://mysite.com/#page2</a> then turns javascript on. The page reloads at the #page2 section which then causes the javascript enabled navigation system to not work correctly. e.g. it reloads thinking the page is at section 1 when it is actually displaying section #whatever.<br /><br />
I have tried adding parent.location.hash = ''; but when the page reloads, it still stays on whichever section it was on.<br /><br />
Any ideas on how to make the page fully refresh when javascript gets turned on?</p>

this.y = y;
this.z = z;
return this;
}
Vector.prototype.length = function () { return Math.sqrt(this.x * this.x ... ); }

Version 1:</p>
<pre><code>public ActionResult Login(LoginData loginData)

<p>Version 2:</p>

4,740,040 | 4,740,041 | why setName in Thread class assigns to a character array?why not a String? | <p>When i was dealing with threads concept in Java, i have seen Thread.java source file. I noticed when <code>setName()</code> method assigns string to a character array called <code>"name[]"</code>. Java has a feature of String data type, then why they are using character array. </p>
<p>In source file it is initialised like,</p>
<pre><code>private char name[]; // why not "private String name;"
</code></pre>
<p>In <code>setName()</code> method,</p>
<pre><code>public final void setName(String name) {
checkAccess();
this.name = name.toCharArray();
}
</code></pre>
<p>Please help me. Thanks in advance.</p>
