  • Flex Filterfunction - Filter by Array of values

    - by Anandh
    How to filter an Arraycollection by "array of values" rather than a single value (simple comparision) , the below code snippet is for filtering by single value now I went into scenario like filter out only price [10,4,1,8] (some random values from the master collection). Is there any better way to do the second code snippet Filter function simple comparision private function filterForTestData(item:Object):Boolean{ if(item.price < slider.value) return true; else return false; } Filter by array of values private function filterForTestData(item:Object,filterBy:Array= [10,4,1,8]):Boolean{ for(randomprice in filterBy) return item.price == randomprice; } [Edited] Apply Filter testData.filterFunction = filterForTestData;

  • Write set of integers to std::ofstream and be able to read them back

    - by bndu
    Hello, I need to write a bunch of unsigned integers to std::ofstream in binary mode: std::ofstream f; f.open("some path", std::ios::out | std::ios::binary); // some loop { unsigned int k = get_k(); // may product numbers from 0 to 65535 f << k; } f.close(); They are written to the output file "as is" w/o any delimiter. So when I'm trying to read them back (expecting to get what I wrote) using std::ifstream I get very strange values. What I'm doing wrong? Or I should to put ' ' (space) to the stream after any added number to separate them? Thanks.

  • add/delete image ID to/from textbox when image clicked

    - by Huseyin
    I am working on a simple news module. There is a form where user adds multiple image IDs to one textbox then submits it. To improve the usability, I listed all the images they can add (ID numbers displayed next to it) on one side. However, this still is little bit confusing. I want image IDs added/deleted to the textbox when user clicks on the images. Spare me codes, methods, ideas, examples... I will take anything.

  • Can Visual Studio exclude certain folders when searching for header files?

    - by identitycrisisuk
    I'm having trouble with a library that we are using, which has two copies of header files that are needed - one which we are modifying and building from and another which is automatically created during the build process. I don't fully know why or really want to change this but it can cause a bit of annoyance when on random occasions the go to definition function takes you to the auto created header instead of the one used to build. Usually you can spot it but sometimes you don't and make changes to the auto created one, which are then overwritten or sometimes stay around for a while so that something works on your machine but breaks on other peoples. I don't know if there is any way around this as the auto created folder is in the additional include directories of some of the projects in the solution but I just thought I would ask if there was any good way of reducing the chance of this annoying situation cropping up.

  • why number 9 in kill -9 command in unix?

    - by Alby
    I understand it's off topic, I couldn't find anywhere online and I was thinking maybe programming gurus in the community might know this. I usually use kill -9 pid to kill the job. I always wondered the origin of 9. I looked it up online, and it says "9 Means KILL signal that is not catchable or ignorable. In other words it would signal process (some running application) to quit immediately" (source: http://wiki.answers.com/Q/What_does_kill_-9_do_in_unix_in_its_entirety) But, why 9? and what about the other numbers? is there any historical significance or because of the architecture of Unix? Thanks!

  • MS SQL - High performance data inserting with stored procedures

    - by Marks
    Hi. Im searching for a very high performant possibility to insert data into a MS SQL database. The data is a (relatively big) construct of objects with relations. For security reasons i want to use stored procedures instead of direct table access. Lets say i have a structure like this: Document MetaData User Device Content ContentItem[0] SubItem[0] SubItem[1] SubItem[2] ContentItem[1] ... ContentItem[2] ... Right now I think of creating one big query, doing somehting like this (Just pseudo-code): EXEC @DeviceID = CreateDevice ...; EXEC @UserID = CreateUser ...; EXEC @DocID = CreateDocument @DeviceID, @UserID, ...; EXEC @ItemID = CreateItem @DocID, ... EXEC CreateSubItem @ItemID, ... EXEC CreateSubItem @ItemID, ... EXEC CreateSubItem @ItemID, ... ... But is this the best solution for performance? If not, what would be better? Split it into more querys? Give all Data to one big stored procedure to reduce size of query? Any other performance clue? I also thought of giving multiple items to one stored procedure, but i dont think its possible to give a non static amount of items to a stored procedure. Since 'INSERT INTO A VALUES (B,C),(C,D),(E,F) is more performant than 3 single inserts i thought i could get some performance here. Thanks for any hints, Marks

    - by iform
    Hi, I am stumped... I am trying to get the following output until a certain condition is met. test_1.jpg test_2.jpg .. test_50.jpg The solution (if you could remotely call it that) that I have is fileCount = 0 while (os.path.exists(dstPath)): fileCount += 1 parts = os.path.splitext(dstPath) dstPath = "%s_%d%s" % (parts[0], fileCount, parts[1]) however...this produces the following output. test_1.jpg test_1_2.jpg test_1_2_3.jpg .....etc The Question: How do I get change the number in its current place (without appending numbers to the end)? Ps. I'm using this for a file renaming tool.

  • How to introduce multi-column constraint with JPA annotations?

    - by plouh
    I am trying to introduce a multi-key constraint on a JPA-mapped entity: public class InventoryItem { @Id private Long id; @Version private Long version; @ManyToOne @JoinColumn("productId") private Product product; @Column(nullable=false); private long serial; } Basically (product, serial) pair should be unique, but I only found a way to say that serial should be unique. This obviously isn't a good idea since different products might have same serial numbers. Is there a way to generate this constraint via JPA or am I forced to manually create it to DB?

  • Having trouble getting GET variables from url.

    - by mchl
    Hey everyone, I'm having trouble with this algorithm to extract the get variables from a url and print them each on a new line like: x=y z=hello etc. but instead it prints a seemingly random section of the url with no newlines to the file. There must be a logic error of some kind but i just can't spot it. for(i_m=0;i_m<len_m;i_m++) { if(var_m[i_m]=='&') { fwrite(var_m+offset_m, 1, amp_m, echo_out); fputc('\n',echo_out); offset_m+=amp_m; amp_m=0; } amp_m++; } any help appreciated.

  • Using template specialization in C++

    - by user550413
    How can I write a function using template specialization that has 2 different input types and an output type: template <class input1, class input2, class output> and return the sum of the 2 numbers (integers/doubles). However, if I get 2 integers I want to return an integer type but for any other combinations of integer and double I'll always return double. I am trying to do that without using directly the '+' operator but having the next functions instead: double add_double_double(double a, double b) {return (a+b);} double add_int_double(int a, double b) {return ((double)(a)+b);} int add_int_int(int a, int b) {return (a+b);}

  • Sorting array of 1000 distinct integers in the range [1, 5000], accessing each element at most once

    - by Cronydevil
    Suppose you have an array of 1000 integers. The integers are in random order, but you know each of the integers is between 1 and 5000 (inclusive). In addition, each number appears only once in the array. Assume that you can access each element of the array only once. Describe an algorithm to sort it. How i can sorting? If you used auxiliary storage in your algorithm, can you find an algorithm that remains O(n) space complexity?

  • Which database should I use for best performance

    - by _simon_
    Hello, I am working in Visual Studio 2005, .NET 2.0. I need to write an application, which listens on COM port and saves incoming data to a database. Main feature: save incoming data (series of 13-digits numbers), if this number allready exists, then mark it as double. For example, there could be these records in database: 0000000000001 OK 0000000000002 OK 0000000000002 Double 0000000000003 OK 0000000000004 OK I could use SQL database, but I don't know if it is fast enough... Database should be able to store up to 10.000.000 records and write up to 100 records per minute (so it needs to check 100 times per minute if this record allready exists). Which database should I use? Maybe the whole database would need to be in RAM. Where could I learn more about this? Thanks

  • Python - a clean approach to this problem?

    - by Seafoid
    Hi, I am having trouble picking the best data structure for solving a problem. The problem is as below: I have a nested list of identity codes where the sublists are of varying length. li = [['abc', 'ghi', 'lmn'], ['kop'], ['hgi', 'ghy']] I have a file with two entries on each line; an identity code and a number. abc 2.93 ghi 3.87 lmn 5.96 Each sublist represents a cluster. I wish to select the i.d. from each sublist with the highest number associated with it, append that i.d. to a new list and ultimately write it to a new file. What data structure should the file with numbers be read in as? Also, how would you iterate over said data structure to return the i.d. with the highest number that matches the i.d. within a sublist? Thanks, S :-)

  • How can I make a table move in JavaScript?

    - by Michal Skrzypek
    My problem is that I was creating a simple website the other day and I needed the content to move according to the button pressed. I managed to do so in CSS3, but the solution did not work for IE whatsoever. Therefore I would like to ask if there is a simple solution for that in js? I don't know js at all but I heard what I need is much easier in js than in css. Details: http://i42.tinypic.com/6yl4ia.png I need the table in the picture to move according to the buttons (which are labels to be exact). The visible area is a div. Here's the relevant code (without animation as I was not satisfied with it): body { background-color: #fff; color: #fff; padding:0px; } #bodywrapperfixed { width: 1248px; margin: 0px auto; position: relative; overflow: hidden; height: 730px; } #bodywrapper { display:block; background-color: #fff; width: 1248px; color: #59595B; padding-top:50px; font-family: 'Roboto', sans-serif; position: absolute; top:0px; left:0px; z-index:1; font-size: 60px; height:730px; } #bodywrapper img { width:400px; padding:15px 0px 20px 0px; } #texten { font-family: 'Roboto', sans-serif; font-size: 35px; padding:5px; } #textpl { font-family: 'Roboto', sans-serif; font-size: 25px; padding:5px; } table#linki { width: 110px; border: none; margin-top:15px; } label { display: block; height: 54px; width: 54px; color:#fff; font-family: 'Roboto', sans-serif; font-weight: 300; font-size: 35px; background-color: #117D10; text-align: center; padding:23px; } label:hover { background-color: #004F00; cursor: pointer; } input#pl { position: absolute; top: -9999px; left: -9999px; } input#en { position: absolute; top: -9999px; left: -9999px; } and the relevant HTML: <div id="bodywrapperfixed"> <div id="bodywrapperfloat"> <table id="ramka"> <tr> <td>random text</td> <td><div id="bodywrapper"> <center> <div id="texten"><div style="font-weight:300; display:inline-block;">Introducing the all-in-one entertainment system.</div><div style="font-weight:500; display:inline-block;">&nbsp;For everyone.</div></div> <div id="textpl"><div style="font-weight:300; display:inline-block;">Przedstawiamy zintegrowany system rozrywki.</div><div style="font-weight:500; display:inline-block;">&nbsp;&nbsp;Dla wszystkich.</div></div> <img src="imgs/xboxone.png"> <div id="texten"><div style="font-weight:300; display:inline-block;">Choose your version of the story:</div></div> <div id="textpl"><div style="font-weight:300; display:inline-block;">Wybierz swoja wersja opowiesci:</div></div> <table id="linki"> <tr> <td><label for="en">en</label><input id="en" type="checkbox"></td> <td><label for="pl">pl</label><input id="pl" type="checkbox"></td> </tr></table> </center> </div></td> <td>random text</td> </tr> </table> </div> </div> Here's what it looks like: http://ingame.lh.pl/thinkone/ Please help me.

  • Reading line by line from a file in C

    What I am trying to do is print out the contents of a file line by line. I run the program in terminal by doing: ./test testText.txt. When I do this, random characters are printed out but not what is in the file. The text file is located in the same folder as the makefile. What's wrong? #include <stdio.h> FILE *fp; int main(int argc, char *argv[]) { char line[15]; fp = fopen(*argv, "r"); while((fgets(line, 15, fp)) != NULL) { printf(line); printf("\n"); } }

  • Most reliable method for uploading files in PHP w/ progress bar

    - by vanneto
    Hello everyone, I am interested in finding the most reliable method for uploading files in PHP. I need a progress bar with the upload. I have tried SWFUpload but it randomly issues an I/O Error. Even if the same file is uploaded sometimes there is an error and sometimes there is not. I have configured all the necessary INI/Mysql/Apache directives to accept large file uploads. So, I am looking for alternatives as a Flash based solution has not worked. Would Java be more relirable? I have also looked into PHP with APC. I definitely cannot afford these random errors, so any help on reliable software / suggestions on how to minimize them would be appreciated. Thank you.

  • Creating a page selector with JSP/JSTL

    - by zakSyed
    I am working on a project where I am required to build a page somewhat similar to the one you see when you visit a website like blockbuster. When you click on browse more you are taken to a page with a bar on top with different page numbers and a drop down to select the number of pages you want to view on that page. I want to include a feature like that on my page but I am not sure where to start. In my page I have list of 200 items which I want to display page by page. I was suggested to use custom tags, but is there a more simpler or efficient way to create that functionality. My web application uses Spring MVC framework and is coded entirely in Java. Any suggestions will be appreciated.

  • mysql row counter

    Hello, I have a mysql table. It has auto increment on the id. but I regularly delete rows so the numbers are all over the place. I need to get the last n rows out, but because of deletions, the common way of using the max of the autoincremented id column doesn't work well... 1 - Is their another way to get the bottom 50? 2 - Is their a way to get rows by actual row number? so if I have 4 rows labelled 1,2,3,4 delete row 2 then it will become 1,2,3 rather than 1,3,4?

  • Detecting when a process has finished (but not exited)

    - by Egwor
    I have a program that's run in unix (that I have no control over) that when finished prints 'Completed successfully' but does not exit. I want to automatically detect when the process finishes (by checking the output of the command), so that I can kill the process and so that I can proceed do other activities. The complexity comes because I want to be able to run multiples of these scripts concurrently. (One activity I need to do requires the script to be called with various inputs, but each time the script runs it takes a while to return, and so I want to do them in parallel) Has anyone done something similar to this? I could redirect the stderr and stdout output of the command to a temporary file which has a random file name, then tail the file and pipe to grep for the end conditions (I.e. the certain log lines). The problem is, surely tail -f would keep running, and so it would never exit. Should I poll? If so, what's the best approach?

  • How to achieve jQuery scrolling/overlay effect (video in description)

    - by waffl
    I have two columns. The left column contains text of dynamic lengths. The right column is of fixed height and will contain a set of images selected at random per page load. I am trying to create an effect where while the user scrolls, the Image 2 scrolls above Image 1. When it reaches the top, the Image 1 begins to scroll up until it disappears, then Image 3 comes in and repeats the process. As this is rather confusing, I made a short video describing the desired effect. Video - MP4 I have begun trying to get it working in this jsbin but am at a loss for when the user scrolls back down and also when more images are required. I am thinking my current path is not the right direction. I'm thinking that employing something like jQuery waypoints is more the direction I should be pursuing?
