  • How to use jQuery .live() with ajax

    - by kylemac
    Currently I am using John Resig's LiveQuery plugin/function - http://ejohn.org/blog/jquery-livesearch/ - to allow users to sort through a long unordered-list of list-items. The code is as follows: $('input#q').liveUpdate('ul#teams').focus(); The issue arises when I use ajaxified tabs to sort the lists. Essentially I use ajax to pull in different lists and the liveUpdate() function doesn't have access to the new li's. I assume I would need to bind this using the .live() function - http://api.jquery.com/live/. But I am unclear how to bind this to an ajax event, I've only used the "click" event. How would I bind the new liveUpdate() to the newly loaded list-items? EDIT: The ajax tabs is run through the wordpress ajax api so the code is fairly complex, but simplified it is something like this: $('div.item-list-tabs').click( function(event) { var target = $(event.target).parent(); var data = {action, scope, pagination}; // Passes action to WP that loads my tab data $.post( ajaxurl, data, function(response) { $(target).fadeOut( 100, function() { $(this).html(response); $(this).fadeIn(100); }); }); return false; }); This is simplified for the sake of this conversation, but basically once the $.post loads the response in place .liveUpdate() doesn't have access to it. I believe the .live() function is the answer to this problem, I'm just unclear on how to implement it with the $.post()

  • Excel VBA Select Case Loop Sub

    - by Zack
    In my excel file, I have a table setup with formulas. with Cells from Range("B2:B12"), Range ("D2:D12"), and etc every other row containing the answers to these formulas. for these cells (with the formula answers), I need to apply conditional formatting, but I have 7 conditions, so I've been using "select case" in VBA to change their interior background based on their number. I have the select case function currently set up within the sheet code, as opposed to it's own macro Private Sub Worksheet_Change(ByVal Target As Range) Dim iColor As Integer If Not Intersect(Target, Range("B2:L12")) Is Nothing Then Select Case Target Case 0 iColor = 2 Case 0.01 To 0.49 iColor = 36 Case 0.5 To 0.99 iColor = 6 Case 1 To 1.99 iColor = 44 Case 2 To 2.49 iColor = 45 Case 2.5 To 2.99 iColor = 46 Case 3 To 5 iColor = 3 End Select Target.Interior.ColorIndex = iColor End If End Sub but using this method, you must be actually entering the value into the cell for the formatting to work. which is why I want to write a subroutine to to do this as a macro. I can input my data, let the formulas work, and when everything is ready, I can run the macro and format those specific cells. I want an easy way to do this, obviously I could waste a load of time, typing out all the cases for every cell, but I figured it'd be easier with a loop. how would I go about writing a select case loop to change the formatting on a a specific range of cells every other row? thank you in advance.

  • Reading Serial Data From C (OSX /dev/tty)

    - by Jud Stephenson
    I am trying to read data from a bluetooth barcode scanner (KDC300) using C. Here is the code I have so far, and the program successfully establishes a bluetooth connection to the scanner, but when a barcode is scanned, no input is displayed on the screen (Eventually more will be done with the data, but we have to get it working first, right). Here is the program: #include <stdio.h> #include <stdlib.h> #include <string.h> #include <unistd.h> #include <fcntl.h> #include <errno.h> #include <termios.h> #include <sys/ioctl.h> int main (int argc, const char * argv[]) { // define vars int STOP = 0; //char buf[255]; if(argv[1]) { int fd = open("/dev/tty.KDC1", O_RDONLY); if(fd == -1) { printf("%s", strcat("Unable to open /dev/tty.", argv[1])); } int res; while(STOP == 0) { while((res = read(fd,buf,255)) == 0); { if(res > 0) { buf[res]=0; printf("%s:%d\n", buf, res); if(buf[sizeof(buf)]=='\n') break; } } } } return 0; } If anyone has any ideas, I am at a loss on this so far. If it is any help, I can run screen /dev/tty.KDC1 and any barcodes scanned on the scanner appear in the terminal, I just can't do anything with the data. Jud

  • Strange \n in base64 encoded string in Ruby

    - by intellidiot
    The inbuilt Base64 library in Ruby is adding some '\n's. I'm unable to find out the reason. For this special example: irb(main):001:0> require 'rubygems' => true irb(main):002:0> require 'base64' => true irb(main):003:0> str = "1110--ad6ca0b06e1fbeb7e6518a0418a73a6e04a67054" => "1110--ad6ca0b06e1fbeb7e6518a0418a73a6e04a67054" irb(main):004:0> Base64.encode64(str) => "MTExMC0tYWQ2Y2EwYjA2ZTFmYmViN2U2NTE4YTA0MThhNzNhNmUwNGE2NzA1\nNA==\n" The \n's are at the last and 6th position from end. The decoder (Base64.decode64) returns back the old string perfectly. Strange thing is, these \n's don't add any value to the encoded string. When I remove the newlines from the output string, the decoder decodes it again perfectly. irb(main):005:0> Base64.decode64(Base64.encode64(str).gsub("\n", '')) == str => true More of this, I used an another JS library to produce the base64 encoded output of the same input string, the output comes without the \n's. Is this a bug or anything else? Has anybody faced this issue before? FYI, $ ruby -v ruby 1.8.7 (2008-08-11 patchlevel 72) [i486-linux]

  • weighted matching algorithm in Perl

    - by srk
    Problem : We have equal number of men and women.each men has a preference score toward each woman. So do the woman for each man. each of the men and women have certain interests. Based on the interest we calculate the preference scores. So initially we have an input in a file having x columns. First column is the person(men/woman) id. id are nothing but 0.. n numbers.(first half are men and next half woman) the remaining x-1 columns will have the interests. these are integers too. now using this n by x-1 matrix... we have come up with a n by n/2 matrix. the new matrix has all men and woman as their rows and scores for opposite sex in columns. We have to sort the scores in descending order, also we need to know the id of person related to the scores after sorting. So here i wanted to use hash table. once we get the scores we need to make up pairs.. for which we need to follow some rules. My trouble is with the second matrix of n by n/2 that needs to give information of which man/woman has how much preference on a woman/man. I need these scores sorted so that i know who is the first preferred woman/man, 2nd preferred and so on for a man/woman. I hope to get good suggestions on the data structures i use.. I prefer php or perl. Thank you in advance

  • Best and easiest algorithm to search for a vertex on a Graph?

    - by Nazgulled
    Hi, After implementing most of the common and needed functions for my Graph implementation, I realized that a couple of functions (remove vertex, search vertex and get vertex) don't have the "best" implementation. I'm using adjacency lists with linked lists for my Graph implementation and I was searching one vertex after the other until it finds the one I want. Like I said, I realized I was not using the "best" implementation. I can have 10000 vertices and need to search for the last one, but that vertex could have a link to the first one, which would speed up things considerably. But that's just an hypothetical case, it may or may not happen. So, what algorithm do you recommend for search lookup? Our teachers talked about Breadth-first and Depth-first mostly (and Dikjstra' algorithm, but that's a completely different subject). Between those two, which one do you recommend? It would be perfect if I could implement both but I don't have time for that, I need to pick up one and implement it has the first phase deadline is approaching... My guess, is to go with Depth-first, seems easier to implement and looking at the way they work, it seems a best bet. But that really depends on the input. But what do you guys suggest?

  • PHP Variable with Array

    - by Crays
    Hi guys, i'm trying to make a "update user's power" page. It is something similar to those you can find in say, invisionfree forums. I need it to generate a list of members with checkbox [done] Add an option for it [done] What i don't know how to do is to update, to say, give all the selected users the selected power. Then i went searching for something and found most of them uses array to do this, but i never found one that actually explains how it works. The example i took (with my own modification) was this: while($row = mysql_fetch_array($result)) { echo '<tr>'.$id[]=$rows['id'].''; echo '<td width="50px" align="center" class="TableFormCell"><input type="checkbox" name="option[]" /></td>'; echo '<td width="170px" align="center" class="TableFormCell">'.$row['uname'].'</td>'; echo '</tr>'; } I'm not sure what exactly $id[]=$rows['id'] does I know after the row, my option[] would become an array of option[1], option[2], option[3] for what power should be given, i've got no problem with that but on how to update the database i'm got no clue... for($i=0;$i<$count;$i++){ $sql1="UPDATE ninos SET power='$power' WHERE id='$option[$i]'"; $result1=mysql_query($sql1); } So Say i have 5 users, Aye, Bee, Cee, Dee, Eee with IDs of 1,2,3,4,5 how can i make it so that my script would run like $sql1="UPDATE ninos SET power = '$power' Where id='1','2','3','4','5'"; Please help, thanks.

  • Ruby page loading very very slowly - how should I speed it up?

    - by Elliot
    Hey guys, I'm going to try and describe the code in my view, without actually posting all the garbage: It has a standard shell (header, footer etc. in the layout) this is also where the sub navigation exists which is based on a loop (to find the amount of options) - on this page, we have 6 subnav links. Then in the index view, we have a 3rd level nav - with 3 links that use javascript to link/hide divs on the page. This means each of those original 6 options, all have their own 3'rd level nav, with each of their own 3 div pages. These three pages/divs have the input form for creating a record in rails, and then the other 2 pages show the records in different assortments. ALL of this code lives on one page (aside from the shell). The original sub nav uses a javascript tab solution, to browse through all of it... (this means its about 6 divs, which all contain 4 divs of function - so about 24 heavy divs). Loading it seems to take forever, although after loaded its extremely fast (obviously). My big question, is how should I attack this? I don't know ajax - although I imagine it'd be a good solution for loading the tabs when clicked. Thanks! Elliot

  • How to submit the form using JQuery UI?

    - by Vafello
    I have a form in html with a default submit button. After the form is submitted, a php file is run (with action = homelocation). I decided to use JQuery UI dialog to display the form. I have 2 default buttons there - one to save and one to close the dialog. Can anyone tell me how to assign the form submit button action to the JQuery dialog button(i.e. replace the submit button from the form with the one in the dialog)? Here's my code: <div id="userdialog" title="Add"> <form id="add" action="engine.php" method="POST"> <input type="hidden" name="action" value="homelocation" id="action"> <button type="submit">Save this location</button> </form></div> Dialog: $('#userdialog').dialog({ width: 260, position: [250,100], buttons: { "Save": function() { HERE GOES THE REQUIRED FUNCTION $(this).dialog('close'); }, "Don't Save": function() { $(this).dialog("close"); } } });

  • Inserting new <TD> elements into a table row.

    - by Hunter S. Smythe
    I have created a small application written in XHTML, JavaScript/JQuery and PHP. The PHP reads and writes to a small SQLite database. How would i go about inserting cells into a pre-scripted table. The cells would need to be configured using some information from my database. For example, below are two cells with their data retrieved from my database: Cell One Starts: 120px; Finishes: 180px; Background: Blue; Cell Two Starts: 240px; Finishes: 300px; Background: Green; On my table row, it is 500px in width. How would I insert the cells above into the row. In this example, the first cell would start 120px into the row and have a width of 180px. The second cell would start 240px into the row and have a width of 300px. I just cant seem to work out a way of doing this, any ideas would be very helpful. Thank you for any input, all is appreciated. Hunter.

  • Jquery UI Datepicker not displaying

    - by scott
    UPDATE I have reverted back to Jquery 1.3.2 and everything is working, not sure what the problem is/was as I have not changed anything else apart of the jquery and ui library versions. UPDATE END I having an issue with the JQuery UI datepicker. The datepicker is being attached to a class and that part is working but the datepicker is not being displayed. Here is the datepicker code I am using and the inline style that is being generated when I click in the input box that has the class ".datepicker". $('.datepicker').datepicker({dateFormat:'dd/mm/yy'}); display:none; left:418px; position:absolute; top:296px; z-index:1; If I change the display:none to display:block the datepicker works fine except it dosen't close when I select a date.

  • Emacs key binding fallback

    - by rejeep
    Hey, I have a minor mode. If that mode is active and the user hits DEL, I want to do some action, but only if some condition holds. If the condition holds and the action is executed I want to do nothing more after that. But if the condition fails, I don't want to do anything and let the default DEL action execute. Not sure how I could solve this. But I guess I could do it in two ways: 1) I could rebind the DEL key to a function in the minor mode and then check if the conditions holds ot not. But then how do I know what the default command to DEL is? 2) I could add a pre command hook like this. Execute the command and then break the chain. But how do I break the chain? (add-hook 'pre-command-hook (lambda() (when (equal last-input-event 'backspace) ;; Do something and then stop (do not execute the ;; command that backspace is bound to) ))) In what way would you solve it? Thanks!

  • Self-referencing tables in Linq2Sql

    - by J-Man
    Hi, I've seen a lot of questions on self-referencing tables in Linq2Sql and how to eagerly load all child records for a particular root object. I've implemented a temporary solution by accessing all underlying properties, but you can see that this doesn't do the performance any good. The thing is though, that all records are correlated with each-other using a correlation GUID. Example below: RootElement - Id: 1 - ParentId: null - CorrelationId: 4D68E512-4B55-44f4-BA5A-174B630A03DD ChildElement1 - Id: 2 - ParentId: 1 - CorrelationId: 4D68E512-4B55-44f4-BA5A-174B630A03DD ChildElement2 - Id: 3 - ParentId: 2 - CorrelationId: 4D68E512-4B55-44f4-BA5A-174B630A03DD ChildElement1 - Id: 4 - ParentId: 2 - CorrelationId: 4D68E512-4B55-44f4-BA5A-174B630A03DD In my case, I do have access to the correlationId, so I can retrieve all of my records by performing the following query: from element in db.Elements where element.CorrelationId == '4D68E512-4B55-44f4-BA5A-174B630A03DD' select element; But, of course, I want these elements associated with each other by executing this query: from element in db.Elements where element.CorrelationId == '4D68E512-4B55-44f4-BA5A-174B630A03DD' && element.ParentId == null select element; My question is: is it possible to combine the results the first query as some sort of 'caching mechanism' for the query where I get the root element? Thanks for the input. J.

  • Liferay hook: filter url giving filterstart error and current url generates exception null

    - by jack
    I'm trying to make an autologinfilter in Eclipse using a liferay hook. Now I've added the: <filter> <filter-name>myautologinfilter</filter-name> <filter-class>bla.bla.xyz</filter-class> </filter> <filter-mapping> <filter-name>myautologinfilter</filter-name> <url-pattern>/c/login/myurl</url-pattern> </filter-mapping> To the liferay hook's web.xml. In the liferay-hook.xml I added: portal.properties And in that hook.xml I added: auto.login.hooks=bla.bla.xyz bla.bla.xyz implements AutoLogin, but for now it's pretty gutted: @Override public String[] login(HttpServletRequest request, HttpServletResponse response) throws AutoLoginException { Object parameters = request.getAttribute("javax.servlet.forward.query_string"); Map<String, String> x = parserClass.parsing(parameters.toString()); System.out.println("voornaam: " + geparsdeParameters.get("tokenvalue1")); try { return null; } catch (Exception e) { throw new AutoLoginException(e); } } Since the hook doesn't start when I add the filtering I removed it and just tried: http://localhost:8080/c/portal/login?tokenvalue1=55 but when I check my tomcat I see: Error XYZ Url: url myUsedUrl exception null Also I tried adding some util classes but I got: classnotfoundexceptions. Is there anything specific I have to do when I add extra classes in a hook? Any advice/input would be appreciated. Or someone's ear I could lend so I could mail them a little bit so I could pick their brain a bit would be really appreciated since I don't know anyone who programs for liferay.

  • rapid application developement tools for very basic GUI apps

    - by Jurij
    I know there are many RAD platforms out there. Infact there are so many that I'm having a hard time finding out which one fits me best. What I want is a RAD tool that would allow me to define a database data model (make DB tables) and then create (view and edit) forms for the various tables. Data input, updating and various queries should be easy and GUI should generate automatically. I'd like to add some additional functionality by coding (such as various complex calculations on the data). I'm a programmer so I'm willing to learn to use a more complete, full-blown RAD solution if you can point me to it (NetBeans and RubyOnRails being the two such frameworks that I'd would probably be high on the list). I'm currently doing Windows Forms logistics apps in .NET. I've actually developed a very crude and basic version of what I need, but I just know that there are solutions out there that are much better and I'd benefit by knowing how to use them. So in short, the basic requirements: * database based data storage (SQLite if possible) * very automated GUI creation * desktop based (as in: not a web app) * extendable by coding * used for creating simple data entry, view & query apps. So basically something like Oracle Forms or DotNetMushroom Rapid Application Developer. But for .NET and SQLite if possible.

  • What's a good way of building up a String given specific start and end locations?

    - by Michael Campbell
    (java 1.5) I have a need to build up a String, in pieces. I'm given a set of (sub)strings, each with a start and end point of where they belong in the final string. Was wondering if there were some canonical way of doing this. This isn't homework, and I can use any licensable OSS, such as jakarta commons-lang StringUtils etc. My company has a solution using a CharBuffer, and I'm content to leave it as is (and add some unit tests, of which there are none (?!)) but the code is fairly hideous and I would like something easier to read. As I said this isn't homework, and I don't need a complete solution, just some pointers to libraries or java classes that might give me some insight. The String.Format didn't seem QUITE right... I would have to honor inputs too long and too short, etc. Substrings would be overlaid in the order they appear (in case of overlap). As an example of input, I might have something like: String:start:end FO:0:3 (string shorter than field) BAR:4:5 (String larger than field) BLEH:5:9 (String overlays previous field) I'd want to end up with FO BBLEH 01234567890

If in rich:calendar component, we manually enter improper date or junk data it will not even call the action method. As per our requirement we need to display an error message for date validation for these kind of fields. Is there any way to track that the date entered in the calendar field is improper with this component. Code for the reference: <rich:calendar id="actualOpeningDtCal" rendered="#{!empty storeProgram.id}" value="#{storeProgram.actualOpeningDate}" placeholder="dd-mmm-yyyy" inputSize="20" enableManualInput="true" datePattern="dd-MMM-yyyy" buttonIcon="../content/images/calendar.png" showWeeksBar="false" showFooter="false"> <a4j:support event="oninputblur" reRender="aList" ajaxSingle="false" action="#{aController.inlineEdit}"> <f:setPropertyActionListener value="#{aProgram}" target="#{aController.inLineEditaBean}" /> </a4j:support> <a4j:support event="oncollapse" reRender="aList" ajaxSingle="false" action="#{aController.inlineEdit}"> <f:setPropertyActionListener value="#{aProgram}" target="#{aController.inLineEditaBean}" /> </a4j:support> </rich:calendar> Regards, Hiral

  • Multithreading and Interrupts

    - by Nicholas Flynt
    I'm doing some work on the input buffers for my kernel, and I had some questions. On Dual Core machines, I know that more than one "process" can be running simultaneously. What I don't know is how the OS and the individual programs work to protect collisions in data. There are two things I'd like to know on this topic: (1) Where do interrupts occur? Are they guaranteed to occur on one core and not the other, and could this be used to make sure that real-time operations on one core were not interrupted by, say, file IO which could be handled on the other core? (I'd logically assume that the interrupts would happen on the 1st core, but is that always true, and how would you tell? Or perhaps does each core have its own settings for interrupts? Wouldn't that lead to a scenario where each core could react simultaneously to the same interrupt, possibly in different ways?) (2) How does the dual core processor handle opcode memory collision? If one core is reading an address in memory at exactly the same time that another core is writing to that same address in memory, what happens? Is an exception thrown, or is a value read? (I'd assume the write would work either way.) If a value is read, is it guaranteed to be either the old or new value at the time of the collision? I understand that programs should ideally be written to avoid these kinds of complications, but the OS certainly can't expect that, and will need to be able to handle such events without choking on itself.

  • How is it that json serialization is so much faster than yaml serialization in python?

    - by guidoism
    I have code that relies heavily on yaml for cross-language serialization and while working on speeding some stuff up I noticed that yaml was insanely slow compared to other serialization methods (e.g., pickle, json). So what really blows my mind is that json is so much faster that yaml when the output is nearly identical. >>> import yaml, cjson; d={'foo': {'bar': 1}} >>> yaml.dump(d, Dumper=yaml.SafeDumper) 'foo: {bar: 1}\n' >>> cjson.encode(d) '{"foo": {"bar": 1}}' >>> import yaml, cjson; >>> timeit("yaml.dump(d, Dumper=yaml.SafeDumper)", setup="import yaml; d={'foo': {'bar': 1}}", number=10000) 44.506911039352417 >>> timeit("yaml.dump(d, Dumper=yaml.CSafeDumper)", setup="import yaml; d={'foo': {'bar': 1}}", number=10000) 16.852826118469238 >>> timeit("cjson.encode(d)", setup="import cjson; d={'foo': {'bar': 1}}", number=10000) 0.073784112930297852 PyYaml's CSafeDumper and cjson are both written in C so it's not like this is a C vs Python speed issue. I've even added some random data to it to see if cjson is doing any caching, but it's still way faster than PyYaml. I realize that yaml is a superset of json, but how could the yaml serializer be 2 orders of magnitude slower with such simple input?

  • Signals and Variables in VHDL - Problem

    - by Morano88
    I have a signal and this signal is a bitvector. The length of the bitvector depends on an input n, it is not fixed. In order to find the length, I have to do some computations. Can I define a signal after defining the variables ? It is ggiving me errors when I do that. It is working fine If I keep the signal before the variables .. but I don't want that .. the length of Z depends on the computations of the variables. What is the solution ? library IEEE; use IEEE.STD_LOGIC_1164.ALL; use IEEE.STD_LOGIC_ARITH.ALL; use IEEE.STD_LOGIC_UNSIGNED.ALL; entity BSD_Full_Comp is Generic (n:integer:=8); Port(X, Y : inout std_logic_vector(n-1 downto 0); FZ : out std_logic_vector(1 downto 0)); end BSD_Full_Comp; architecture struct of BSD_Full_Comp is Component BSD_BitComparator Port ( Ai_1 : inout STD_LOGIC; Ai_0 : inout STD_LOGIC; Bi_1 : inout STD_LOGIC; Bi_0 : inout STD_LOGIC; S1 : out STD_LOGIC; S0 : out STD_LOGIC ); END Component; Signal Z : std_logic_vector(2*n-3 downto 0); begin ass : process Variable length : integer := n; Variable pow : integer :=0 ; Variable ZS : integer :=0; begin while length /= 0 loop length := length/2; pow := pow+1; end loop; length := 2 ** pow; ZS := length - n; wait; end process; end struct;
