Please let me know when a call to shmat function can raise a signal 11.
if ((shmId=shmget(shmKey, 0, 0)) <= 0) {
printf( "shmget(0x%x)", shmKey);
return 0;
}
printf( "queueOpen - Key 0x%x gives ID %d", shmKey, shmId);
qh = shmat(shmId, 0, SHM_RND);
I am getting a signal 11 by the code above. Please help

hei guys
i want to select two divs with the same id in jquery. how do i do it?
i tried this and it did not work
jQuery('#xx').each(function(ind,obj){
//do stuff;
});
i have jquery countdown timers in a page, and i update them via ajax. some of these countdown timers repeat and that is why i need to use the same id on the divs.
hi,
I cannot click on the links (tags) on top of the page in IE7.
I tried to change z-index of the elements but it doesn't work.
Could you tell me what's wrong with it ? http://www.sanstitre.ch/drupal/portfolio?tid[0]=38
The mouse click is handled by jQuery function .click()
I'm sure javascript works because" Hide - Alphabetical Order menus" work
thanks
It seems that JMenuItems don't automatically resize any image icon that's assigned to them, and from what I can tell, there isn't a property that makes them automatically do that, either.
Is anyone aware of a way that I can programatically resize the Icon for a JMenuItem? It seems like the Icon object is lacking functionality as it is, unless there's some other function that can actually deal with Icon objects.
Ahh i'm stuck again. helpp
why do i encounter this
"can't find variable: $j"
when i use this method
function myMethod(htmlObject)
{
var buttonTags = $j("button",htmlObject);
...
}
Sorry for askin silly questions again. running outta time =\
THANKS FOR THEHELP!

but how to show the result in th same page that has the form
I want to cut the svn/cvs recods in pieces and then put in to database. After that i can make use of those data easily.
Any java function can get out the record? and How?
If possible, please provide a example. Thank you.
Hey.
My code crashes at this function (at the stringByAppendingFormat: with error objc_msgSend() selector name: stringByAppendingFormat).
This is that line:
// imagesPath = ...iPhone Simulator/4.0/Applications/NUMBERS/Documents/images
UIImage *image = [[UIImage alloc] initWithContentsOfFile:[imagesPath stringByAppendingFormat:@"/%d.png", [[self.postsArrayID objectAtIndex:row] intValue]]];
Could it have something to do with the retaining of objects?
Thanks :)
Is there any framework, whick allows to mock concrete classes, not only interfaces in java 1.4? I have third party code with a singleton class, where I wanna change one function, without touching orignal code. Is it possible?
I want my users to be logged out automatically after X minutes of inactivity. I also want to have all sessions destroyed.
How can this be done? How can I check for inactivity then perform a function to log them out???
Is there a way to stop other subs from running while in a separate sub.
for instance say your in the sub
CreateNumber()
and the subs are setup like
CreateNumber()
AddNumber()
DeleteNumber()
Is there a way to be in CreateNumber() and call a function to stop AddNumber from running after creaetNumber() is finished? i just want my program to sit there to wait for an event to happen.
Lets say I have something like...
void foo()
{
char c[100];
printf("this function does nothing useful");
}
When foo is called, it creates the array on the stack, and when it goes out of scope, is the memory deallocated automatically? Or is c destroyed, but the memory remains allocated, with no way to access it/get it back except restarting the computer?
I want to find top rated item using AVG function in mysql, right now my query looks like this:
SELECT a.title, AVG(d.rating) as rating FROM in8ku_content a
JOIN in8ku_content_ratings d ON a.id = d.article_id
ORDER BY rating DESC
Problem is that it takes AVG of all items and the result is not accurate, what should be changed here to get correct result ?
Tables:
in8ku_content [id, title] in8ku_content_ratings [id, article_id, rating]
Hi,
this is my first question on Stackoverflow, please bear with me.
I'm testing an algorithm for 2d bin packing and I've chosen PHP to mock it up as it's my bread-and-butter language nowadays.
As you can see on http://themworks.com/pack_v0.2/oopack.php?ol=1 it works pretty well, but you need to wait around 10-20 seconds for 100 rectangles to pack. For some hard to handle sets it would hit the php's 30s runtime limit.
I did some profiling and it shows that most of the time my script goes through different parts of a small 2d array with 0's and 1's in it. It either checks if certain cell equals to 0/1 or sets it to 0/1. It can do such operations million times and each times it takes few microseconds.
I guess I could use an array of booleans in a statically typed language and things would be faster. Or even make an array of 1 bit values. I'm thinking of converting the whole thing to some compiled language. Is PHP just not good for it?
If I do need to convert it to let's say C++, how good are the automatic converters? My script is just a lot of for loops with basic arrays and objects manipulations.
Thank you!
Edit. This function gets called more than any other. It reads few properties of a very simple object, and goes through a very small part of a smallish array to check if there's any element not equal to 0.
function fits($bin, $file, $x, $y) {
$flag = true;
$xw = $x + $file->get_width();;
$yh = $y + $file->get_height();
for ($i = $x; $i < $xw; $i++) {
for ($j = $y; $j < $yh; $j++) {
if ($bin[$i][$j] !== 0) {
$flag = false;
break;
}
}
if (!$flag) break;
}
return $flag;
}
Hi,
I have a mySql database i want to display only 10 words from its body field which contain html codes, How i can do that, is there any php function to do that.
Is there any efficient way in python to count the times an array of numbers is between certain intervals? the number of intervals i will be using may get quite large
like:
mylist = [4,4,1,18,2,15,6,14,2,16,2,17,12,3,12,4,15,5,17]
some function(mylist, startpoints):
# startpoints = [0,10,20]
count values in range [0,9]
count values in range [10-19]
output = [9,10]
Long story short. Clone() returns object and my code expects a cmd bc i was working with another lib but nearly the same interface. How can i use define or 'using' to have it call a function extension? I tried extending with the name Clone but it was ignored. However it does see Clone2()
All I want to do is on .click() is .animate #slip, essentially Im changing the css at the moment from top: 10px to top: 0px
Instead of it being quite clunky i'd like to animate the movement on the change of CSS.
Currently use .toggleClass to achieve this:
$("#div1").click(function() {
$("#div2t").toggleClass('min');
});
I have a column defined like this:
<DataGridTextColumn Binding="{Binding Path=FileSizeBytes, Mode=OneWay}" Header="Size" IsReadOnly="True" />
But instead of displaying the file size as a big number, I'd like to display units, but still have it sort by the actual FileSizeBytes. Is there some way I can run it through a function or something before displaying it?
I'm trying to replace elements of a data.frame containing "#N/A" with "NULL", and I'm running into problems:
foo <- data.frame("day"= c(1, 3, 5, 7), "od" = c(0.1, "#N/A", 0.4, 0.8))
indices_of_NAs <- which(foo == "#N/A")
replace(foo, indices_of_NAs, "NULL")
Error in [<-.data.frame(*tmp*, list, value = "NULL") :
new columns would leave holes after existing columns
I think that the problem is that my index is treating the data.frame as a vector, but that the replace function is treating it differently somehow, but I'm not sure what the issue is?
