<p>and examples also its good and very intresting to use but as per examples all values are predefine .As we can't guess the max execution time of programm or function.So i am not able to figure out how should i use progress bar function in my sctipt</p>

2,202,431 | 2,202,432 | Expand/shrink image in a div with JQuery | <p>I'm using some images as banners on my site. They're full (960px) width and I initially show a portion of the image as a teaser (say 160px high). I do this now by using a separate image which is a slice of the full size image (which is 600px high). Complicating this are shadows that I apply in Photoshop at the top and bottom of the image that make it look "inset" into the div.</p>
<p>What I would like to do is overlay the image with a small icon that says something like "see more". When the visitor clicks on this icon I'd like to div to expand (acordian style) to show the whole image and then change the icon to "see less". When the new icon is clicked I'd like the image to collapse to its original size.</p>
<p>I suspect that I will need to use a new image (960 x 600px) that I've also added shadows to so I can retail the inset look. So, this requires two images, one that is swapped out when the div is expanding and contracting and one that is swapped in when the div contracts to the original 160px height.</p>
<p>Complicating this is the fact that the image acts as a banner near the top of the page and I don't want the div to expand upwards past the window top so as to disappear off-screen and possibly add a scrollbar. A final complication is that the small "slice" can be taken at any height in the original 600px image. I select an area of the image that looks best at 160px. So, the div expansion is not constant in height. If the slice is cut from the top of the original image, the div will only expand a bit at the top and much more at the bottom. Similarly with slices cut from the bottom of the original image.</p>
<p>I realize this is a complicated question, and I did Google around quite a bit looking for solutions. I found a couple of JQuery extensions (UI and Tools) that look like they might be usable, but I could find no examples of what I'm trying to do. If the answer is too complicated to attempt in this forum, pointers to sites that do what I'm trying to accomplish would be appreciated.</p>

4,173,671 | 4,173,672 | Reusing a property value from within an object initializer | <p>First of all sorry for the intriguing title of my question, hopefuly a code sample exposing my problem will clarify things.</p>
<p>Below you will find a code sample that does not compile (and I totally get why, no need to explain) but which expose what I am trying to achieve:</p>
<pre><code>public class Cmd
{
public Byte MyByte { get; set; }
public Byte MyOtherByte { get; set; }
public String MyString { get; set; }
public static Cmd FromStream(Stream stream)
{
return new Cmd
{
MyByte = (Byte)stream.ReadByte(),
MyOtherByte = (Byte)stream.ReadByte(),
MyString = SomeMethodBasedOnMyOtherByte(MyOtherByte) // Here
};
}
}
</code></pre>
<p>I hope you get the idea. Of course if the stream is seekable I could just seek back one byte and reread it for passing it as the argument of the method I am calling. But if the stream is non seekable, no way.</p>
<p>This is a very basic example of course, in my real scenario the classes on which I would like to implement FromStream have many different properties.</p>
<p>Is there any keyword that allows to do what I am trying to do, basically reusing an affected property value from within an object initializer block ?</p>
<p>If not I guess the only way for me would be not to use an object initializer in this context, and construct a new object affecting it's properties one by one (so that I can reuse affected properties if needed). And wouldn't it be nice to have (or reuse) a keyword for this specific scenario in object initializer ? If not, why ?</p>
<p>Thanks !</p>

Myset = CacheConverter.MakeDictionary(_myList);

<p>Please explain why.</p>
<p>why <code>($s == $d)</code> results as true?</p>
<p>Of course, if <code>===</code> is used it will results as false but why this situation requires <code>===</code>?
Shouldn't it be returned false in both situations?</p>

2,182,092 | 2,182,093 | How do I define a class that can only be instantiated via new (ie not on the stack)? | <p>I want to arrange things such that for a class Foo, this works:</p>
<pre><code>Foo *f = new Foo()
</code></pre>
<p>but this does not (preferably a compile-time error):</p>
<pre><code>Foo f;
</code></pre>
<p>Can this be done?</p>
<p>The specific reason is that Foo is actually a tracking class to make another heap-allocated object appear in a script environment. Foo's internals keeps a mapping from script references to C++ objects. The tracking object would be used like this:</p>
<pre><code>Thing *t = new Thing();
(new FooThing(t))->PushToScriptStack();
</code></pre>
<p>If the tracking object is on the stack then the pointer becomes invalid at the end of scope, and I'm left with dangling pointers in my tracking data.</p>
<p>I have all this working well, I'm just looking for a little extra protection.</p>

156,300 | 156,301 | Is it possible to synchronize data members and not methods? | <p>After reading topics here about Java synchronized methods, I've tried to implement it in my multiplayer game because many threads are opened and trying to access the same resource.
I've made methods synchronized but that's doesn't help me since if I have a data member called ArrayList clientConnection; and the methods that are available are:</p>
<pre><code>int getArrayListSize() {
clientConnection.size();
}
void addConnection(ServerConnection i_connection) {
clientConnection.add(i_connection);
}
void removeConnection(ServerConnection i_connection) {
int index = clientConnections.indexOf(i_Connection);
clientConnections.remove(index);
}
ServerConnection getClientFromArrayListByIndex(int i_Index) {
ServerConnection client = this.clientConnections.get(i_Index);
}
</code></pre>
<p>I've tried to make a global synchronized method to whenever one want to use one of the methods he needs to pass in an operation type and other data and he locks the function.
The problem is that there are 2 function that return void, 1 returns int and 1 returns ServerConnection so I can't create that global method.
My question if there is a possible to lock data members and not methods in Java so I can lock the clientConnection data member?
Thanks.</p>
