However my first attempt is giving me an error "cannot use ref or out parameter inside an anonymous method body".
public static class IntEx {
public static Action CreateIncrementer(ref int reference) {
return () => {
reference += 1;
};
}
}
I understand why the compiler doesn't like this, but nonetheless I'd like to have a graceful way to provide a nice incrementer factory that can point to any integer. The only way I'm seeing to do this is something like the following:
public static class IntEx {
public static Action CreateIncrementer(Func<int> getter, Action<int> setter) {
return () => setter(getter() + 1);
}
}
But of course that is more of a pain for the caller to use; requiring the caller to create two lambdas instead of just passing in a reference. Is there any more graceful way of providing this functionality, or will I just have to live with the two-lambda option? | c# | lambda | anonymous-methods | ref | null | null | open | C# Cannot use ref or out parameter inside an anonymous method body

Normally when using VMWare Server 1.0.7 you are asked if you would like to connect to the local machine or a remote host. Installing the same software on 64-bit Windows 2008 only gives the remote host option.
I have tried entering the local machine name as the host and entering creds that have admin rights to the server but I just get a "Cannot connect as the target machine actively rejected it" error. I have tried to find a solution on Google, but with no joy.
Anyone run into this before and can point me in the right direction? | 2 |

I'm not sure why intval returns that big numbers on my local server, but it shouldn't work like that.
$i + 0; seems to be the best method.

It's purpose is for people to upload drink recipes and be able to view other peoples uploaded drink recipes. Each drink recipe, when clicked on, fades in a mini canvas box and makes the background fade dark. Each drink recipe has a like button within the now visible drink recipe popup, and each of these drink recipes can be accessed through the url, if the drink is shared so that the shared link doesn't just lead to the page with all the recipes listed, but the actual shared recipe popup:
http://www.example.com/myapp.php?user_id=10009098039&dname=MyDrink
The user_id and dname will run through a function that displays the drink recipe popup.
Because the app is housed my testing website and displayed through facebook, which obviously uses an iframe to display it, a drink cannot be shared because the link will take the user back to where the app is housed. Is it possible to be able to manipulate the iframe with the parent window's link?
Ex: https://facebook.com/pages/Test-Page/4080982098230923?sk=app_209302098302?user_id=10009098039&dname=MyDrink

Now when specifying a message to be logged the category is shown as (1) instead of my predefined value (OurDatabase), the message text (Bla Bla) however is shown correctly.
Additionally, the EventSource display name is not showing (it shows OurLog instead of Our own log), but frankly I don't really care, but it may help diagnose my problem.
What am I missing?
BTW, I've seen a few times the use of

<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
I wonder, should I write the **<title>** and **<meta description/keywords>** tags with an '`&`' or an '`&`' instead?
Just as an example:
<title>Dolce & Gabbana</title>
or
<title>Dolce & Gabbana</title>
I can't use the word **'and'** simply because it doesn't "look" as good.
Thanks

input: "new york city", output: "+york* +city*" ("new" is a stopword).
I have an ugly solution that works: explode the search string into an array of words, look up each word in the array of stopwords, unset them if there is a match, implode the remaining words and finally run a regex to add the boolean mode formatting. There has to be a more elegant solution.
My question has 2 parts.
1) What do you think is the cleanest way to do this?
2) I solved part of the problem using a huge regex but this raised another question.
What's the difference in memory usage between the following sets of preg_replace commands?
(this set would solve my problem but throws a memory exhausted error)
$tmp = preg_replace('/(\b('.implode('|',$stopwords).')\b)+/','',$this->val);
$boolified = preg_replace('/([^\s]+)/','+$1*',$tmp);
(in this set the first and second statement are decoupled and I do not get a memory error. Unfortunately, it doesn't solve my problem either...)

I basically open a socket, listen, wait for a connection and open a new socket from which I read the data sent by the client. So far so good. But how do I know the client has finished sending data and not simply temporarily stopped sending more because of some other reason?
My current example: When the client sends a POST-request, it first sends the headers, then two times "\r\n" in a row and then the request body. Sometimes the body does not contain any data. So if the client is temporarily unable to send anything after it sent the headers - how do I know it is not yet finished with its request?
Does this solely depend on the used protocol (HTTP) and it is my task to find this out on the basis of the data I received, or is there something like an EOF for sockets?
If I cannot get the necessary Information from the socket, how do I protect my program from faulty clients? (Which I guess I must do regardless of this, since it might be an attacker and not a faulty client sending wrong data.) Is my only option to keep reading until the request is complete by definition of the protocol or a timeout (defined by me) is reached?
I hope this makes sense.

Well on every post i am displaying the post the user made and the date and the name of the user however i would like the ajax functionality (two buttons that increment the or decrement the value of num on click) to display the result in the div that the users post was made in, however the value of num is being displayed in the first status div for all the div rather than each div individually. | javascript | html | css | ajax | div | 07/23/2012 09:58:53 | not a real question | How to make ajax work in every CSS div

For some reason when one hovers over a point on my datechart the tool tip does not adhere to the points position. The video below shows exactly what's happening - I found this example on youtube. It's the same exact issue but no solution is mentioned.
http://www.youtube.com/watch?v=SyiNoDmFR7o
The charts data is coming back as a JSON object which I have validated in JSONlint. So there are no issues with malformed data messing things up. Also, there are no errors in my JS console.
Here is my default options setting which I have in a PHP class
$chartsettings = array(
'chart' => array(
'renderTo' => 'highchart',
'type' => 'spline',
'zoomType' =>'x',
'backgroundColor' =>'transparent'
),
'title' => array(
'text' => '',
),
'subtitle' => array(
'text' => '',
),
'legend' => array(
'layout' => 'vertical',
'align' => 'right',
'verticalAlign' => 'top',
'x' => -10,
'y' => 100,
'borderWidth' => 0
),
'xAxis' => array(
'type' => 'datetime',
'maxzoom' => 3600000,
),
'yAxis' => array(
'max' => null,
'min' => null,
'title' => array(
'text' => 'Number of Visits',
),
),
);
Thanks in advance!

I mean the 3d side mostly
If i make normal character, that has flat clothes, it would be easy, just change textures, but question is about armors, which have totally different models.
So are only armor models recreated or character model with armor?
How is it imported into game engine, only armor or character model with new armor?
If person changes armor in game, will game swap the hole model or only the armor part?
if only the armor part, then how the movement animations are done, are armor models animated on characters in 3d programs or what... :D | 3d | unity | maya | 3dsmax | null | null | open | How RPG characters are made
