  • on .bind('click') it is not deleting the first div

    - by Jean
    Hello, When I click on a particular div, that div should fade out, simple, but when I click on one of the divs it deletes the div on top of the stack. ie., when I click #sel6 it removes sel5 html code <div id="selc" class="selc" style="position:absolute; left:15px; top:200px; width:260px;"> <div id="sel5" class="sel">something</div> <div id="sel6" class="sel">something</div> <div id="sel7" class="sel">something</div> </div jquery code sel_id, sel_1 are variables $('.selc').bind('click',function(){ var sel_id = $('.sel').attr('id'); alert(sel_id); $('#'+sel_id).fadeOut('slow'); $('#'+sel_id).remove(); $('.search_box').append(sel_1); }); Thanks Jean

  • Possible to exclude or reorder a column from `*` ?

    - by Earlz
    Is it possible to exclude a column from a select * from table statement with SQL Server? I have a need for this and this is my only option other than parsing a raw SQL string to get out the required field names (I really don't want to do that). Just to be bold. When the query is made I do not have access to the list of fields needed from the table but I do know which field I do not need. This is part of a complex multi-part query. Surely there must be some way even if it's "hackish" such as using table variables or views My other option is to reorder the columns. My problem is with ExecuteScalar SQL functions which get the first row and first column.

  • Seeking assistance with Escaping Data for MySQL queries

    - by JM4
    Please don't send me a link to php.net referencing mysql_real_escape_string as the only response. I have read through the page and while I understand the general concepts, I am having some trouble based on how my INSERT statement is currently built. Today, I am using the following: $sql = "INSERT INTO tablename VALUES ('', '$_SESSION['Member1FirstName'], '$_SESSION['Member1LastName'], '$_SESSION['Member1ID'], '$_SESSION['Member2FirstName'], '$_SESSION['Member2LastName'], '$_SESSION['Member2ID'] .... and the list goes on for 20+ members with some other values entered. It seems most people in the examples already have all their data stored in an array. On my site, I accept form inputs, action="" is set to self, php validation takes place and if validation passes, data is stored into SESSION variables on page 2 then redirected to the next page in the process (page 3) (approximately 8-10 pages in the whole process). thanks!

  • 16 millisecond quantization when sending/receivingtcp packets

    - by MKZ
    Hi, I have a C++ application running on windows xp 32 system sending and receiving short tcp/ip packets. Measuring (accurately) the arrival time I see a quantization of the arrival time to 16 millisecond time units. (Meaning all packets arriving are at (16 )xN milliseconds separated from each other) To avoid packet aggregation I tried to disable the NAGLE algorithm by setting the IPPROTO_TCP option to TCP_NODELAY in the socket variables but it did not help I suspect that the problem is related to the windows schedular which also have a 16 millisecond clock.. Any idea of a solution to this problem ? Thanks

  • Handling a binary operation that makes sense only for part of a hierarchy.

    - by usersmarvin_
    I have a hierarchy, which I'll simplify greatly, of implementations of interface Value. Assume that I have two implementations, NumberValue, and StringValue. There is an average operation which only makes sense for NumberValue, with the signature NumberValue average(NumberValue numberValue){ ... } At some point after creating such variables and using them in various collections, I need to average a collection which I know is only of type NumberValue, there are three possible ways of doing this I think: Very complicated generic signatures which preserve the type info in compile time (what I'm doing now, and results in hard to maintain code) Moving the operation to the Value level, and: throwing an unsupportedOperationException for StringValue, and casting for NumberValue. Casting at the point where I know for sure that I have a NumberValue, using slightly less complicated generics to insure this. Does anybody have any better ideas, or a recommendation on oop best practices?

  • Visibility of elements by ID

    - by dragonfly
    Hi, how come that when I attach onchange by attribute and call it onchange="validateDate(FPR_CURR_FROM);" it works, but when I use a ASP .NET validator, and my attached function is called like : function anonymous() { ValidatorOnChange(event); validateDate(FPR_CURR_FROM); } I get error: FPR_CURR_FROM is undefined. First off: I know that using FPR_CURR_FROM to access element is BAD, and I should use getElementByID etc... And I will change it eventually. But as I bumped into that code, I'm curious what caused it - propably visibility of variables I guess.

  • Parsing C# Script into Java

    - by pantaryl
    I'm looking for a way to easily read in a C# file and place it into a Java Object for database storage (storing the class name, functions, variables, etc). I'm making a Hierarchical State Machine AI Building Tool for a game I'm creating and need to be able to import an existing C# file and store it in a database for retrieval in the future. Does anyone know of any preexisting libraries for parsing C# files? Something similar to JavaParser? Thanks everyone! EDIT: This needs to be part of my Java Project. I'll be loading in the C# files through my Java Application and saving it into my db4o database.

  • Arrange 0's & 1's in a array

    - by Ganesh M
    This is one of an interview question which I had recently. I would like to know others perception of approach for this problem. Question: You are given a structure which holds an employee details with two elements as int Deptartment and string Name. struct Employee { string Name; int Dept; } You are given details of N Employees among which there are N/2 employees Dept are 0's and N/2 employees dept are 1's arranged in some random order. You need to sort the employee details based on their Dept value and it should be stable i.e., the order of 1s and 0s in the original record should be maintained. For example, given the following sample data: Name Dept X1 0 X2 1 X3 0 X4 1 X5 0 after sorting the result should be: Name Dept X2 1 X4 1 X1 0 X3 0 X5 0 The algorithm should be stable and the complexity should be o(N), with constant space for additional variables (which means sorting should be done in-place).

  • Why is 'using namespace std;' considered a bad practice in C++?

    - by Mana
    Okay, sorry for the simplistic question, but this has been bugging me ever since I finished high school C++ last year. I've been told by others on numerous occasions that my teacher was wrong in saying that we should have "using namespace std;" in our programs, and that std::cout and std::cin are more proper. However, they would always be vague as to why this is a bad practice. So, I'm asking now: Why is "using namespace std;" considered bad? Is it really that inefficient, or risk declaring ambiguous vars(variables that share the same name as a function in std namespace) that much? Or does this impact program performance noticeably as you get into writing larger applications? I'm sorry if this is something I should have googled to solve; I figured it would be nice to have this question on here regardless in case anyone else was wondering.

First of all, the user fill an html table with the values that he has selected and written in the form. after that he will find his parameters displayed in the html table. the problem now is : the table contains in each row an edit button when clicking on it; the user should have the form automatically filled with values"previously selected" of the row. so it's how to reload the form with variables from html table. Note : I construct the table with a servlet. Please help.

  • from JS to iphone dev - what's the best language to start with?

    - by Enkai
    I am a total beginner and would like to eventually learn to develop for the iphone. I have just done a beginner's CS course where the language we learned was JavaScript. We studied basic concepts like: variables, arrays, loops (for,while,if,if..else..), properties and functions. I'm wondering if I am starting in the right/wrong place by following this book: Learn C on the Mac by Dave Mark? I have read a few chapters and am finding it a bit hard to get my head around the way that C works, for example the way that Strings are printed seems overly complicated as compared to JS. Do you think that JS was the wrong language to start off with and would I be better to go from JS straight to Objective-C rather than to C? I have tried to read up on previous threads on the merits/demerits of learning C first but haven't found any that relate JS to learning C/Obj C/ Cocoa. Any advice appreciated as I am very new to this. Thanks

  • php string to array and split

    - by RussP
    Hi folks Looking for suggestions as to the best way to do this (I know there are many options): take a variable like this: $args = ('post_type=post&order_by=DESC&limit=10'); the create a function to convert that variable into parts like this: $post_type = post; $order_by = DESC; $limit= 10; Reason is I want a client to be able to use a string like the first to pass variables to a sql query in much the same way (but doesn't have to be exact) as you can do it in WordPress.

  • ASP.NET - How can I cache user details for the duration of their visit?

    - by rockinthesixstring
    I've built a Repository that gets user details Public Function GetUserByOpenID(ByVal openid As String) As User Implements IUserRepository.GetUserByOpenID Dim user = (From u In dc.Users Where u.OpenID = openid Select u).FirstOrDefault Return user End Function And I'd like to be able to pull those details down IF the user is logged in AND IF the cached data is null. What is the best way to create a User object that contains all of the users details, and persist it across the entire site for the duration of their visit? I Was trying this in my Global.asax, but I'm not really happy using Session variables. I'd rather have a single object with all the details inside. Private Sub BaseGlobal_AcquireRequestState(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.AcquireRequestState If Session("UserName") Is Nothing AndAlso User.Identity.IsAuthenticated Then Dim repo As UrbanNow.Core.IUserRepository = New UrbanNow.Core.UserRepository Dim _user As New UrbanNow.Core.User _user = repo.GetUserByOpenID(User.Identity.Name) Session("UserName") = _user.UserName() Session("UserID") = _user.ID End If End Sub

  • Counting multiple rows in MySQL in one query

    - by diggersworld
    I currently have a table which stores a load of statistics such as views, downloads, purchases etc. for a multiple number of items. To get a single operation count on each item I can use the following query: SELECT , COUNT() FROM stats WHERE operation = 'view' GROUP BY item_id This gives me all the items and a count of their views. I can then change 'view' to 'purchase' or 'download' for the other variables. However this means three separate calls to the database. Is it possible to get all three in one go?

  • Is it bad practice to use Reflection in Unit testing?

    - by Sebi
    During the last years I always thought that in Java, Reflection is widely used during Unit testing. Since some of the variables/methods which have to be checked are private, it is somehow necessary to read the values of them. I always thought that the Reflection API is also used for this purpose. Last week i had to test some packages and therefore write some JUnit tests. As always i used Reflection to access private fields and methods. But my supervisor who checked the code wasn't really happy with that and told me that the Reflection API wasn't meant to use for such "hacking". Instead he suggested to modifiy the visibility in the production code. Is it really bad practice to use Reflection? I can't really believe that

  • What magical thing could be killing my Drupal session and anywhere from 15-45 minutes of activity?

    - by jini
    I am using a standard Drupal install hosted on a LAMP stack. My settings.php has the following set: ini_set('session.gc_probability', 1); ini_set('session.gc_divisor', 100); ini_set('session.gc_maxlifetime', 200000); ini_set('session.cookie_lifetime', 2000000); my php.ini file has: session.gc_probability = 1 session.gc_divisor = 1000 session.gc_maxlifetime = 1440 Also I have checked that the safe mode is off so that my settings.php file is able to override main php.ini variables. Also since the person can get log out at 15 minutes, it is making me wonder whether php.ini has anything to do with it anyways. I have combed through my code and it seems to work fine on my local host however on server it is having issues. Where else can i possibly check?????

  • echoing our parts of an Array?

    - by Wes
    I have the following array that I get as an output from facebook: http://www.paste.to/v/1jntlnml With the following code: $stream = $facebook->api_client->stream_get('',128342905144,'0','0',30,'','','',''); foreach($stream as $wallpost) { echo '<pre>'; print_r($wallpost); echo '</pre>'; } So I get the data that I need, but I want to call the individual variables within this array. For example, echo out the [message] for each post. Since it only loops once, I cant echo $wallpost['message'] or anything similar. any idea?

    - by Nitesh Panchal
    Hello, I am using the below given code, but it is not working properly. Can anybody tell me how do i generate thumbnail of the image? because i am creating a photo album and i want only thumbnail images to be downloaded at first, not the entire 400-500 kb images. File objFile = new File(strImageFullPath); File targetFile = new File(strImageFullPathWithoutExt + "_small" + strFileExtension); Image image = ImageIO.read(objFile); final int WIDTH = 150; final int HEIGHT = 150; Image thumbnailImage = image.getScaledInstance(WIDTH, HEIGHT, Image.SCALE_DEFAULT); BufferedImage objThumbnailBufferedImage = new BufferedImage(WIDTH, HEIGHT, BufferedImage.TYPE_INT_RGB); Graphics gfx = objThumbnailBufferedImage.getGraphics(); gfx.drawImage(image, 0, 0, null); gfx.dispose(); ImageIO.write(objThumbnailBufferedImage, strFileExtension.substring(1), targetFile); Just assume that few variables like strImageFullPath,strImageFullPathWithoutExt etc they exist. Thanks in advance :)

  • Create numbers within an array that add up to a set amount

    - by RussellDias
    I'm fairly new to PHP - programming in general. So basically what I need to accomplish is, create an array of x amount of numbers (created randomly) who's value add up to n: Lets say, I have to create 4 numbers that add up to 30. I just need the first random dataset. The 4 and 30 here are variables which will be set by the user. Essentially something like x = amount of numbers; n = sum of all x's combined; create x random numbers which all add up to n; $row = array(5, 7, 10, 8) // these add up to 30 Also, no duplicates are allowed. I need the values with an array. I have been messing around with it sometime, however, my knowledge is fairly limited. Any help will be greatly appreciated. Cheers

  • Simple Java math operations

    - by user1730056
    I'm making a BMI calculator that doesn't seem to be working. The math operations work if i just do something like w/h, but once i had the brackets, it returns an error. If i change the variables w and h and use a constant number, the operation works. Another problem is that although i'm making result a double, it seems to be rounding to the nearest int. Could someone tell me what I'm doing wrong here? public class ass10 { public static void main(String[] args) { bmi(223,100); } public static bmi(int w, int h){ double result; result = (w/(h*h))*703 System.out.println(result) } }

I just put this below line and getting error in it.. TypeInitializationException Global.BlockLogOut = True; The weird thing is, it was working fine for many months and i am getting this error now on the above line. Of course i was modifying some other stuffs in the application, but surely not this class file. What would have been the problem? namespace Daemon { class Global { public static bool BlockLogOut = false; } }

  • How can I get cmake to find my boost installation

    - by BD at Rivenhill
    I have installed the most recent version of boost in /usr/local (with includes in /usr/local/boost and libraries in /usr/local/lib/boost) and I am now attempting to install Wt from source, but cmake (version 2.6) can't seem to find the boost installation. It tries to give helpful suggestions about setting BOOST_DIR and Boost_LIBRARYDIR, but I haven't been able to get it to work by tweaking these variables. The most recent error message that I get is that it can't find the libraries, but it seems to indicate that it is using "/usr/local/include" for the include path, which isn't correct (and I can't seem to fix it). Does anybody have a solution for this off the top of their head, or do I need to go mucking around inside cmake to figure it out?

  • Is MSDN referencing a system.thread, a worker thread, an io thread or all three?

    - by w0051977
    Please see the warning below taken from the StreamWriter class specification (http://msdn.microsoft.com/en-us/library/system.io.streamwriter.aspx): "Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe." I understand that a W3WC process contains two thread pools i.e. worker threads and I/O threads. A worker thread could contain many threads of its own (if the application creates its own System.Thread instances). Does the warning only relate to System.Threads or does it relate to worker threads and I/O threads as well I.e. as the instance variables of the streamwriter class are not thread safe then does this mean that there would be problems if multiple worker threads access it eg if two users on two different web clients attempt to write to the log file at the same time, then could one lock out the other?

  • Controlling Too Many listboxes ( C#)

    I have almost 200 listboxes. I'm changing their visibility according to my variables from database. So I thought that, I prepared a arraylist. like this ListBox[] lbs = this.Controls.OfType<ListBox>().ToArray(); And used like this. for (int idx = 0; idx < Convert.ToInt32(ds.Tables[j].Rows[i][2])*12; idx++) lbs[idx].Visible = true; This codes are written to comboboxchange. Now everything is okay. But; example; first time I changed combobox 1-20 listboxes visible=true I changed combobox again not 1-20. 20,40 changing :S How can it be, can u tell me an alternative array list type, or another way?
