Actually I'm working with BufferedImages, that provide me pixel values in int type.
Do you know a Java object to represent an image that the pixel value in double or float type?
I am building a website on top of nhibernate. Is there any efficient way to build reports? BY reports, I mean is there anyway to execute a complicated query that grabs random pieces of data? StoreProcedures? Hql?
Can I get single, non mapped values from hql?
All lines in my AppStats look like this: real=19ms cpu=0ms api=0ms overhead=0ms, it has the correct real time, but the other values are always 0. Anyone have this problem before or know how to fix this?
I need to find random nodes according to random attribute values.
To do that I use getAtrribute on nodes from getElementsByTagName.
It seems like when I look for class name as attribute it does not work on IE (works on FF).
Anyone know if getAtrribute doesn't work only on 'class' or other attributes as well? (if its only class I'll do a workaround.)
Does anyone know how to count the number of times a value appears in a matrix?
For example, if I have a 1500 x 1 matrix M (vector) which stores the values of weekdays (1 - 7), how could I count how many Sundays (1), Mondays(2), ... , Saturdays(7) are stored in M?
Hi,
With the following entity relationship structure I'm struggling to figure out if the relationship between the LOAN and ITEM is valid?
The weak entity of Loan uses a partial key of 'loan_dateLeant' and the primary keys from CUSTOMER and ITEM to form its primary key.
However LOAN has a 'one to many' relationship with ITEM as a loan can consist of more than one item.
But surely this means that if more than one item is loaned, then the loan record will have two item_id values for part of its primary key?
I've set up a view which combines all the data across several tables. Is there a way to write this so that only columns which contain non-null data are displayed, and those columns which contain all NULL values are not included?
Hello, I have a web application. On the client side I basically need to get the values of some fields and turn them into JSON and then send them to the server in an AJAX kind of way.(asynchronous)
How would you do that? I also am using jQuery
Hi,
In an if statement with multiple conditions is second executed if the outcome is clear after checking the first condition?
example:
if(i>0 && array[i]==0){
}
If I swap the conditions a seg fault may occur for negative values of i but this way the memory debugger doesn't find a problem. Can I be sure that this works always or do have have to use nested if statements?
Hello,
I have a for loop that loops over one array...
for i=1:length(myArray)
In this loop, I want to do check on the value of myArray and add it to another array myArray2 if it meets certain conditions. I looked through the Matlab docs, but couldn't find anything on creating arrays without declaring all their values on initialization or reading data into them in one shot.
Many thanks!
is it correct to unset the session variable for a particular index as the vay whole session is made unset in PHP?
I know this works: unset($_SESSION['bannersize'])
But does this works ? : unset($_SESSION['bannersize'][3])
or is there any other way to unset any particular desired index of the session and then again rearrange the values inside it to remove the empty index..?

SELECT *
FROM Venue
WHERE Name Like '%cafe%'
So if there is a venue with the name Big Bobs Café Extraordinaire it would be included in the result set?

I have a very stupid issue
if (updateYN.ToUpper() != Constants.NO
|| updateYN.ToUpper() != Constants.N)
{
// execute code for any other updateYN
}
I am trying to perform a filteration that if the value of updateYN is not NO(Constants.NO) or N(Constants.N), then execute the statement.
But the problem is that , irresptive of the values , the if block is executing.
What wrong is there

What is the difference between a Map and a Dictionary? I am not asking for how they are defined in language X or Y(which seems to be what generally people are asking here on SO), I want to know what is their difference in theory.
I know a Map is an object that maps keys to values. Isn't a Dictionary the same?
Thanks
Hi everybody,
I was thinking about the possibility of accessing all the variables that are passed into an function, and merge them into an array. (Without passing variables into an array from the beginning)
Pseudo-code:
// Call function
newFunction('one', 'two', 'three' ) ;// All values are interpreted as a one rray in some way
// Function layout
newFunction( ) {
// $functionvariables = array( All passed variables)
foreach ($functionvariable as $k => $v) {
// Do stuff
}
}
Consider i have a registartion table and there is field prefLocationId and it contains value like this 1,2,3,2,1,4 and so many.... And i have a table prefLocation which looks like this
Id LocationName
1 Chennai
2 Mumbai
3 Kolkatta
4 Delhi
and i want to select record of users and show values like
Chennai,Mumbai,Kolkatta,Mumbai,Chennai,Delhi and so on...
I have a column using IDs that I want to sort by. It has ID values from 1 to 3. However, instead of just using ASC of DESC, I want to do a custom sort by 2, 3, 1. How do I make this happen?
Hi guys, I've got this table
CREATE TABLE `subevents` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`title` varchar(150) DEFAULT NULL,
`content` text,
`class` tinyint(4) NOT NULL DEFAULT '1',
PRIMARY KEY (`id`)
) ENGINE=MyISAM
Each row can have a different value in the 'class' field.
I'd like to select any number of rows, ordered randomly, as long as the sum of the values in the 'class' field is equal to 100.
How could I accomplish it directly in the MySQL query without doing it later in PHP?
Thanks everybody!
Hi,
Every time when I change some values in form controls, I need to set a property of an object or vice versa. Instead of writing some methods for each control, I want a general solution for GUI elements. I do not use WPF but only C# 3.0.
Any suggestions?
Thanks.
Hi All,
How do I get the parameters that are available in the request Header? When I login to a site, I need to see the values that are available in the request header.Is it possible to get that information using any Addons? Can someone please help me to find this?
Thanks in advance
My database consists of some entries which are NULL (so they don't affect max, min, etc..). When I pull all of the data from the database, I need to repopulate form fields with the values. Using .val(value) where value = NULL seems to work without any problems, but I'm not sure if this is a valid way to go about this. It doesn't say anything in the jQuery documentation (that I can find) about using NULL as parameters to functions.
