PHP/JS/JQUERY: Smart method to Auto check/updating a points status

- by Azzyh

Hello. Hi everyone. So right now I am using me of this: function checkpoints() { var postThis = 'checker.php?userid='+ $('#user_id_points').val(); $.post(postThis, function(data){ $(".vispoints").html(data).find(".vispoints1").fadeIn("slow") }); setTimeout(checkpoints, 5000); } This function repeats each 5 seconds (sending request each 5 seconds) and running the checker.php each 5 seconds, to show how many points you got. (checker.php echo out how many points you've got in a span class vispoints1). Now isnt there a smarter method doing this, instead of sending requests like this all the time.. I mean sites like facebook and that, they dont do like this to check if you e.g got a new friend request? Hope you can help me find a better method examples would be good too.

Calling private constructors with Reflection.Emit?

- by Jakob Botsch Nielsen

I'm trying to emit the following IL: LocalBuilder pointer = il.DeclareLocal(typeof(IntPtr)); il.Emit(OpCodes.Ldarg_0); il.Emit(OpCodes.Stloc, pointer); il.Emit(OpCodes.Ldloca, pointer); il.Emit(OpCodes.Call, typeof(IntPtr).GetMethod("ToPointer")); il.Emit(OpCodes.Ret); The delegate I bind with has the signature void* TestDelegate(IntPtr ptr) It throws the exception Operation could destabilize the runtime. Anyone knows what's wrong? EDIT: Alright, so I got the IL working now. The entire goal of this was to be able to call a private constructor. The private constructor takes a pointer so I can't use normal reflection. Now.. When I call it, I get an exception saying Attempt by method <built method> to access method <private constructor> failed. Apparently it's performing security checks - but from experience I know that Reflection is able to do private stuff like this normally, so hopefully there is a way to disable that check?

Changing A Different Class Display on Hover with Jquery

- by John K

Ok, here's what I'm trying to do. I have a DIV box with a child element set with DISPLAY: NONE;. I'm trying to use Jquery so that when the mouse enters the parent DIV box, the child element is made visible, and then hides when the mouse leaves the parent DV. There will be multiple divs on the page with these classes. For some reason it's not working. Any ideas? Here's my code: HTML: <div class="parent"> <span class="handle" style="display: none;">My Handle</span> <p>Child Text</p> </div> Javascript: $(document).ready(function () { $('.parent').mouseenter(function(){ $(this).next('.handle').show(); }); $('.parent').mouseleave(function(){ $(this).next('.handle').hide(); }); })

How to write a JOIN statement to combine data from disparate tables

- by Amarundo

I have the following 2 procedures that I use as my source for a report. As of now, I'm presenting 2 different tables in my SQL Server Reporting Services 2008 R2 report, because it doesn't let me put them together as they belong to 2 different data sets. I want to present them in a single table, but I have not been successful trying to use JOIN here. How do I do that? NOTE: cName in IAgentQueueStats corresponds to UserId in AgentActivityLog. /*** Aggregate values for Call Center Agents for calls, talk and hold time ***/ /*** The detail/row values is per 30-minute interval ***/ ALTER PROCEDURE [dbo].[sp_IAgentQueueStats_OnlyCalls_Grouped] @p_StartDate datetime, @p_EndDate datetime, @p_Agents varchar(8000) AS SELECT [cName] ,sum([nAnswered]) SumNAnswered ,sum([nAnsweredAcd]) SumNAnsweredAcd ,sum([tTalkAcd]) SumTTalkAcd ,sum([nHoldAcd]) SumNHoldAcd ,sum([tHoldAcd]) SumTHoldAcd ,sum([tAcw]) SumTAcw FROM [I3_IC].[dbo].[IAgentQueueStats] WHERE dIntervalStart between @p_StartDate and DATEADD(s, 86400-1, @p_EndDate) AND CHARINDEX ( cName ,@p_Agents)> 0 AND cReportGroup <> '*' AND cHKey3 = '*' and cHKey4 ='*' AND nEnteredAcd > 0 AND cReportGroup <> 'CCFax Email' GROUP BY cName And here is the second one: /*** Aggregate values for Call Center Agents for status/activity time ***/ /*** The detail/row values is per start-time/end-time ***/ ALTER PROCEDURE [dbo].[sp_AgentActivity_Grouped] @p_StartDate datetime, @p_EndDate datetime, @p_Agents varchar(8000) AS SELECT [UserId],[StatusCategory],SUM([StateDuration]) [StatusDuration] FROM ( SELECT [UserId] ,[StatusGroup] ,[StatusKey] , CASE [StatusKey] WHEN 'Available' THEN 'Productive' WHEN 'Follow Up' THEN 'Productive' WHEN 'Campaign Call' THEN 'Productive' WHEN 'Awaiting Callback' THEN 'Productive' WHEN 'In a Meeting' THEN 'Not Your Fault' WHEN 'Project Work' THEN 'Not Your Fault' WHEN 'At a Training Session'THEN 'Not Your Fault' WHEN 'System Issues' THEN 'Not Your Fault' WHEN 'Test' THEN 'Not Your Fault' WHEN 'At Lunch' THEN 'Non Productive' WHEN 'Available, Forward' THEN 'Non Productive' WHEN 'Available, Follow-Me' THEN 'Non Productive' WHEN 'At Play' THEN 'Non Productive' WHEN 'AcdAgentNotAnswering' THEN 'Non Productive' WHEN 'Do Not Disturb' THEN 'Non Productive' WHEN 'Available, No ACD' THEN 'Non Productive' WHEN 'Away from desk' THEN 'Non Productive' ELSE [StatusKey] END StatusCategory ,stateduration FROM [I3_IC].[dbo].[AgentActivityLog] WHERE [StatusDateTime] between @p_StartDate and DATEADD(s, 86400-1, @p_EndDate) AND CHARINDEX ( [UserId] ,@p_Agents)> 0 AND [StatusKey] not in ('Gone Home','Out of the Office','On Vacation','Out of Town') ) a GROUP BY [UserId],[StatusCategory] ORDER BY [UserId], [StatusCategory] desc BTW, if I take some time to comment/reply on your posts, it's not lack of interest, but of understanding...

Does waitpid yield valid status information for a child process that has already exited?

- by dtrebbien

If I fork a child process, and the child process exits before the parent even calls waitpid, then is the exit status information that is set by waitpid still valid? If so, when does it become not valid; i.e., how do I ensure that I can call waitpid on the child pid and continue to get valid exit status information after an arbitrary amount of time, and how do I "clean up" (tell the OS that I am no longer interested in the exit status information for the finished child process)? I was playing around with the following code, and it appears that the exit status information is valid for at least a few seconds after the child finishes, but I do not know for how long or how to inform the OS that I won't be calling waitpid again: #include <assert.h> #include <pthread.h> #include <stdio.h> #include <stdlib.h> #include <unistd.h> #include <sys/wait.h> int main() { pid_t pid = fork(); if (pid < 0) { fprintf(stderr, "Failed to fork\n"); return EXIT_FAILURE; } else if (pid == 0) { // code for child process _exit(17); } else { // code for parent sleep(3); int status; waitpid(pid, &status, 0); waitpid(pid, &status, 0); // call `waitpid` again just to see if the first call had an effect assert(WIFEXITED(status)); assert(WEXITSTATUS(status) == 17); } return EXIT_SUCCESS; }

Get variable name as string in Perl

- by Jose Cuervo

Hi, I am trying to get a text representation of a variable's name. For instance, this would be the function I am looking for: $abc = '123'; $var_name = &get_var_name($abc); #returns '$abc' I want this because I am trying to write a debug function that recursively outputs the contents of a passed variable, I want it to output the variable's name before hand so if I call this debug function 100 times in succession there will be no confusion as to which variable I am looking at in the output. I have heard of Data::Dumper and am not a fan. If someone can tell me how to if it's possible get a string of a variable's name, that would be great. Thanks!

Connecting data to a GUI - OOP

- by tau

I have an application with several graphs and tables on it. I worked fast and just made classes like Graph and Table that each contained a request object (pseudo-code): class Graph { private request; public function setDateRange(dateRange) { request.setDateRange(dateRange); } public function refresh() { request.getData(function() { //refresh the display }); } } Upon a GUI event (say, someone changes the date range dropdown), I'd just call the setters on the Graph instance and then refresh it. Well, when I added other GUI elements like tables and whatnot, they all basically had similar methods (setDateRange and other things common to the request). What are some more elegant OOP ways of doing this? The application is very simple and I don't want to over-architect it, but I also don't want to have a bunch of classes with basically the same methods that are just routing to a request object. I also don't want to set up each GUI class as inheriting from the request class, but I'm open to any ideas really.

C++ design related question

- by Kotti

Hi! Here is the question's plot: suppose I have some abstract classes for objects, let's call it Object. It's definition would include 2D position and dimensions. Let it also have some virtual void Render(Backend& backend) const = 0 method used for rendering. Now I specialize my inheritance tree and add Rectangle and Ellipse class. Guess they won't have their own properties, but they will have their own virtual void Render method. Let's say I implemented these methods, so that Render for Rectangle actually draws some rectangle, and the same for ellipse. Now, I add some object called Plane, which is defined as class Plane : public Rectangle and has a private member of std::vector<Object*> plane_objects; Right after that I add a method to add some object to my plane. And here comes the question. If I design this method as void AddObject(Object& object) I would face trouble like I won't be able to call virtual functions, because I would have to do something like plane_objects.push_back(new Object(object)); and this should be push_back(new Rectangle(object)) for rectangles and new Circle(...) for circles. If I implement this method as void AddObject(Object* object), it looks good, but then somewhere else this means making call like plane.AddObject(new Rectangle(params)); and this is generally a mess because then it's not clear which part of my program should free the allocated memory. ["when destroying the plane? why? are we sure that calls to AddObject were only done as AddObject(new something).] I guess the problems caused by using the second approach could be solved using smart pointers, but I am sure there have to be something better. Any ideas?

Interrupting `while loop` with keyboard in Cython

- by linello

I want to be able to interrupt a long function with cython, using the usual CTRL+C interrupt command. My C++ long function is repeatedly called inside a while loop from Cython code, but I want to be able, during the loop, to send an "interrupt" and block the while loop. The interrupt also should wait the longFunction() to finish, so that no data are lost or kept in unknown status. This is one of my first implementation, which obviously doesn't work: computed=0; print "Computing long function..." while ( computed==0 ): try: computed = self.thisptr.aLongFunction() except (KeyboardInterrupt, SystemExit): computed=1 print '\n! Received keyboard interrupt.\n' break; (p.s. self.thisptr is the pointer to the current class which implements aLongFunction() )

jQuery Custom Lightbox issue

Dirty Reads in Postgres

- by User1

I have a long running function that should be inserting new rows. How do I check the progress of this function? I was thinking dirty reads would work so I read http://www.postgresql.org/docs/8.4/interactive/sql-set-transaction.html and came up with the following code and ran it in a new session: SET SESSION CHARACTERISTICS AS SERIALIZABLE; SELECT * FROM MyTable; Postgres gives me a syntax error. What am I doing wrong? If I do it right, will I see the inserted records while that long function is still running? Thanks

How to pass common arguments to Perl modules

- by Leonard

I'm not thrilled with the argument-passing architecture I'm evolving for the (many) Perl scripts that have been developed for some scripts that call various Hadoop MapReduce jobs. There are currently 8 scripts (of the form run_something.pl) that are run from cron. (And more on the way ... we expect anywhere from 1 to 3 more for every function we add to hadoop.) Each of these have about 6 identical command-line parameters, and a couple command line parameters that are similar, all specified with Euclid. The implementations are in a dozen .pm modules. Some of which are common, and others of which are unique.... Currently I'm passing the args globally to each module ... Inside run_something.pl I have: set_common_args (%ARGV); set_something_args (%ARGV); And inside Something.pm I have sub set_something_args { (%MYARGS) =@_; } So then I can do if ( $MYARGS{'--needs_more_beer'} ) { $beer++; } I'm seeing that I'm probably going to have additional "common" files that I'll want to pass args to, so I'll have three or four set_xxx_args calls at the top of each run_something.pl, and it just doesn't seem too elegant. On the other hand, it beats passing the whole stupid argument array down the call chain, and choosing and passing individual elements down the call chain is (a) too much work (b) error-prone (c) doesn't buy much. In lots of ways what I'm doing is just object-oriented design without the object-oriented language trappings, and it looks uglier without said trappings, but nonetheless ... Anyone have thoughts or ideas?

Javascript hasOwnProperty does not work under Google Chrome

- by WebRookie

I am currently working with some help and it has been going well, until this incident. function runCommand(commandString) { commands = new Object(); commands.clear = function(){ $('#terminal').html('') } parameters = commandString.split(" "); command = parameters.shift(); if( commands.hasOwnProperty(command)){ commandscommand; } else { $('#terminal').append(command+' command not recognized.'+''); } } The person who was helping me made this function, so I could run the "terminal-like" browsers that I needed to work on. It works fine when using Firefox, heres an example: guest@shell:/$ sudo make me sandwich sudo command not recognized. guest@shell:/$ clear *clears* guest@shell:/$ clear But under google chrome this happen: guest@shell:/$ sudo make me sandwich sudo command not recognized. guest@shell:/$ clear clear command not recognized. I believe that it has something to do with "commands.hasOwnProperty(command)" that is preventing it from working properly. I am using JQuery the javascript library to build the website, and I need to know how to solve this problem, or an alternative.

SSL_CTX_set_cert_verify_callback vs. SSL_CTX_set_verify

- by BreakPoint

Hello, Can anyone tell me what is the difference between SSL_CTX_set_cert_verify_callback and SSL_CTX_set_verify? From OpenSSL docs: SSL_CTX_set_cert_verify_callback() sets the verification callback function for ctx. SSL objects that are created from ctx inherit the setting valid at the time when SSL_new(3) is called. and: SSL_CTX_set_verify() sets the verification flags for ctx to be mode and specifies the verify_callback function to be used. If no callback function shall be specified, the NULL pointer can be used for verify_callback. So I'm trying to understand which callback to send for each one (from client side). Thanks experts.

JavaScript, transform object into array

- by Šime Vidas

I've got an object: var obj = { "Mike": 24, "Peter": 23, "Simon": 33, "Tom": 12, "Frank": 31 }; I want to create an array that holds the values of the object. The keys (key names) can be disregarded: [24, 23, 33, 12, 31] The order of the values is NOT important! One solution (obviously) would be do have a function that takes the values and puts them into an array: var arr = valuesToArray(obj); I will accept such a function as the answer. However, I would be more pleased if there would be an API function (ECMAScript, jQuery, browser-specific, ...) that could do this. Is there such a thing?

How do I output JSON columns in jQuery

- by Mel

I'm using the qTip jQuery plugin to create dynamic tool tips. The tooltip sends an id to a cfc which runs a query and returns data in JSON format. At the moment, the tooltip loads with the following: {"COLUMNS:" ["BOOKNAME","BOOKDESCRIPTION"["MYBOOK","MYDESC"]]} Here's the jQuery $('#catalog a[href]').each(function() { var gi = parseInt($(this).attr("href").split("=")[1]) $(this).qtip( { content: { url: 'cfcs/viewbooks.cfc?method=bookDetails', data: { bookID: gi }, method: 'get', title: { text: $(this).text(), button: 'Close' } }, api :{ onContentLoad : function(){ } }, }); }); As I mentioned, the data is returned successfully, but I am unsure how to output it and format it with HTML. I tried adding content: '<p>' + data.BOOKNAME + '' to api :{ onContentLoad : function(){ ..... to see if I could get it to output something, but I get a 'data is undefined error' What is the correct way to try and output this data with html formatting? Many thanks!
