You can use the sched_setaffinity() system call to lock a thread to a specific set of CPUs/cores. In most cases doing that is a bad idea and it will only slow down your system.

Thank you very much. This instruction was created so it must have some useful functions beside causing system slow down. But first of all, I need to try it. Once again, thanks.

hi i would like to know how to sort my dynamic generated table in php when i click on any header row on first click sort acending and on another click sort on decending order. 
|
|
|
|

If you wanna sort Mysql Data, you should use two difference Mysql Query.
For example :
SELECT * FROM table1 ORDER BY filed ASC
SELECT * FROM table1 ORDER BY filed DESC
Else if you wanna sort a table in client you should use JavaScript.

ya i know these are two commands to show asc and desc but i would like to know that i have a grid table in php and on every field i want to do this and show a image full process to do this this grid is filled by while loop as used in php all dataare there but i want to show sorting on header of the fields click.

I think you want to load a table and then be able to sort the data by a column after the data is loaded by clicking on the col header, correct? Uh oh, i think i may like jQuery too much as i just posted a different response pointing the user to the jQuery library.
Take a look at ajaxrain.com for table plugins to jQuery. I know there's a couple of them out there, if this is what you're looking for

There would be 3 components to this process-
1. User-facing page with <div id=data></div>
2. AJAX Javascript
3. Dynamic PHP page
The user-facing page will contain an empty div marked by an ID. The AJAX script will be something like-
http://whatsaranjit.com/includes/grabData.js[^]
Lastly, the PHP page will contain a script like-
$sql = "SELECT * FROM table";
if (isset($_GET['q'])) {
$q = $_GET['q'];
$sql .= " ORDER BY $q ASC";
}
On your user-facing page, you can make your table header a hyperlink-
<a href='javascript: grabData('headerName', 'data', page.php)'>Sort</a>
When you click the link, it will refresh the SQL query data into the div named 'data' appending the SQL query to order by whatever variable you pass to the AJAX script. You can expand on this to to get it to ascend/descend. Good luck!

Need Linux library to get the pixel information from any image.
Example: By providing location(widht, height) x, y values, we should get the information of the pixel which is located at x and y position.
If any one knows about this, please help me.
Thanks in Advance

Have you tried following function?
unsigned long XGetPixel(XImage *ximage, int x, int y);
For more information you can see man XGetPixel.

You could always make this field a VARCHAR (10) instead, which means that the field can take a null value; then, just insert any actual dates in the format YYYY-MM-DD, leaving fields blank where you want to, and then when you read the data from the database again, check if it's not null and if so parse it using a function like date_parse().

hi
i am using php with apachi and mysql with dreamcoder
1. if i am not enter date in my date filed than message incorrect value in my application user can leave this field blank how to do this.
2. i want that user can only input numeric value in my phone filed.
3. email validation
and tell me how to use this in php.

If you want the validation to be done client-side, before the form is submitted, then use JavaScript.
If you want the validation to be done server-side, after the form is submitted but before the data is processed, then use PHP.
Once you have decided which of these options to use, look on the Internet where you'll find a plethora of examples for both methods.

Form validation using Javascript is a browser-side function. You aren't really using PHP to do this. At max, PHP is used to generate Javascript calls. This is the code that I use on my sites and it works very well-

When you check all or check many and POST the information, you'll want to processing script to take the POST values and process them one at a time. You can use the foreach() function to do this-
foreach($_POST AS $field => $value) {
mysql_query("DELETE FROM table WHERE $field='$value' LIMIT 1");
}
Make sure the name parameter of the checkbox is identical to the name of field (case-sensitive). This will cycle through and delete all rows where the fields are equal to the specified values. For more information, see-

I guess it's an AJAX question, Not PHP.
However you should use AJAX.
For that you should learn JAVASCRIPT.
But I suggest ,use Prototype[^] Framework.
It's easy.
