• “User Control” uses an incorrect event

  - by Lijo

  Hi, I am using two instances of a user control. But when I click on a button in the user control, both of the instances calls the function corresponding to the first event (AcknowledgeReceipt()) However, when I remove the first user control and clicks on the btnRequestClarification, it calls the correct method (RequestClarification()) Is there a way to correct this behavior? acknowledgeModificationPopupCtrl = (ConfirmationPopup)this.LoadControl("~/ConfirmationPopup.ascx"); plHConfirmationPopup.Controls.Add(acknowledgeModificationPopupCtrl); acknowledgeModificationPopupCtrl.ContinueClick += new EventHandler(AcknowledgeReceipt); RequiredFieldValidator reqFValidatorAcknowledge = (RequiredFieldValidator)acknowledgeModificationPopupCtrl.FindControl("reqValidatorTxt"); reqFValidatorAcknowledge.ValidationGroup = "AcknowledgeReceipt"; acknowledgeModificationPopupCtrl.ValidationGroup = "AcknowledgeReceipt"; btnAcknowledgeReceipt.Attributes.Add("onclick", "validateconfirmPopup('true','xx' ,’yyy','Note' ,'true'); return false;"); requestModificationPopupCtrl = (ConfirmationPopup)this.LoadControl("~/ConfirmationPopup.ascx"); plHConfirmationPopup.Controls.Add(requestModificationPopupCtrl); requestModificationPopupCtrl.ContinueClick += new EventHandler(RequestClarification); RequiredFieldValidator reqFValidator = (RequiredFieldValidator)requestModificationPopupCtrl.FindControl("reqValidatorTxt"); reqFValidator.ValidationGroup = "request"; requestModificationPopupCtrl.ValidationGroup = "request"; btnRequestClarification.Attributes.Add("onclick", "validateconfirmPopup('true',’kkk' ,’lll','ff' ,'true'); return false;"); Thanks Lijo

• Is there command-line tool to extract typedef, structure, enumeration, variable, function from a C or C++ file?

  - by FooF

  I am desiring a command-line tool to extract a definition or declaration (typedef, structure, enumeration, variable, or function) from a C or C++ source file. Also a way to replace an existing definition/declaration would be handy (after transforming the extracted definition by a user-submitted script). Is there such generic tool available, or is some resonably close approximation of such a tool? Scriptability and ability to hook-up with user created scripts or programs is of importance here, although I am academically curious of GUI programs too. Open source solutions for Unix/Linux camp are preferred (although I am curious of Windows and OS X tools too). Primary language interests are C and C++ but more generic solution would be even better (I think we do not need super accurate parsing capabilities for finding, extracting and replacing a definition in a program source file). Sample Use Cases (extra - for the curious mind): Given deeply nested structs and variable (array) initializations of these types, suppose there is a need to change a struct definition by adding or reordering fields or rewriting the variable/array definitions in more readable format without introducing errors resulting from manual labor. This would work by extracting the old initializations, then using a script/program to write the new initializations to replace the old ones. For implementing a code browsing tool - extract a definition. Decorative code generation (e.g. logging function entries / returns). Scripted code structuring (e.g. extract this and that thing and put in different place without change - version control commit comment could document the command to perform this operation to make it evident and verifiable that nothing changed). Note about tags: More accurate tag than code-generation would be code-transformation but it does not exist.

• regex numeric data processing: match a series of numbers greater than X

  - by Mu Mind

  Say I have some data like this: number_stream = [0,0,0,7,8,0,0,2,5,6,10,11,10,13,5,0,1,0,...] I want to process it looking for "bumps" that meet a certain pattern. Imagine I have my own customized regex language for working on numbers, where [[ =5 ]] represents any number = 5. I want to capture this case: ([[ >=5 ]]{3,})[[ <3 ]]{2,} In other words, I want to begin capturing any time I look ahead and see 3 or more values = 5 in a row, and stop capturing any time I look ahead and see 2+ values < 3. So my output should be: >>> stream_processor.process(number_stream) [[5,6,10,11,10,13,5],...] Note that the first 7,8,... is ignored because it's not long enough, and that the capture ends before the 0,1,0.... I'd also like a stream_processor object I can incrementally pass more data into in subsequent process calls, and return captured chunks as they're completed. I've written some code to do it, but it was hideous and state-machiney, and I can't help feeling like I'm missing something obvious. Any ideas to do this cleanly?

• Fade in and out a div contains video embedHTML in jquery

  - by Ahmy

  I have a div and three links when a link is clicked the div is set its innerHTML with an embedHTML of video and i need to cause some effects when the current div video is changed on clicking the link Example : <a id="Link1" onClick="ChangeVideo(1)">Link1</a> <a id="Link2" onClick="ChangeVideo(2)">Link2</a> <a id="Link3" onClick="ChangeVideo(3)">Link3</a> <div id="CurrVideo"></div> <script type="text/javascript" language="javascript"> //The ArrEmbed is an array that is set on the load of the page:: var ArrEmbed = new Array(); function ChangeVideo(index) { $('#CurrVideo).fadeTo(1000,0.25,function(){ document.getElementById("CurrVideo").innerHTML = ArrEmbed[index-1]; }); $('#CurrVideo).fadeTo(500,1.25); } </script> The effect is not noticeable and fading with opacity diminshing is not noticed even if the duration time is increased (e.g. 'slow') and when i replace the EmbedHTML with image this code is applicable and the effect of fading is noticed but with the video it is not noticeable so how can i solve this problem ? Thanks in advance for any try Note: The embedHTML differ as it may come from youtube or any server or from my JWPlayer.

• Image not rendering in dompdf

  - by Venkat

  I am using codeIgniter and dompdf for my application for generating pdfs. The below code is the code which i am using to display an image. <div class=\"block_head\"> <h2>Image display</h2>"; $image_location = "/images/xxx.png"; $html .="<img src=\"".$image_location."\" width=\"200\" height=\"200\" /> </div>"; I tested and debugged all ways whether i am doing something wrong. Like this first i checked whether the path is wrong. This is path on the server. It's correct. I tested by echoing $html also it's showing perfectly path. When i clicked on that path image is displaying. But when i am trying to render it in pdf it's not displaying. Note: PDF is generating perfectly without image.

• Java reflection Method invocations yield result faster than Fields?

  - by omerkudat

  I was microbenchmarking some code (please be nice) and came across this puzzle: when reading a field using reflection, invoking the getter Method is faster than reading the Field. Simple test class: private static final class Foo { public Foo(double val) { this.val = val; } public double getVal() { return val; } public final double val; // only public for demo purposes } We have two reflections: Method m = Foo.class.getDeclaredMethod("getVal", null); Field f = Foo.class.getDeclaredField("val"); Now I call the two reflections in a loop, invoke on the Method, and get on the Field. A first run is done to warm up the VM, a second run is done with 10M iterations. The Method invocation is consistently 30% faster, but why? Note that getDeclaredMethod and getDeclaredField are not called in the loop. They are called once and executed on the same object in the loop. I also tried some minor variations: made the field non-final, transitive, non-public, etc. All of these combinations resulted in statistically similar performance. Edit: This is on WinXP, Intel Core2 Duo, Sun JavaSE build 1.6.0_16-b01, running under jUnit4 and Eclipse.

• Stop functions in 5 minutes if they dont end running

  - by george mano

  I want to add a feature in my project. I have 2 functions running in a for-loop because I want to find the solution of the functions in random arrays. I also have an function that makes random arrays. In each loop the array that is made by the random_array fun are the input of the 2 functions. The 2 functions print solutions in the screen , they dont return an argument. int main(){ for (i=0;i<50 i++) { arr1=ramdom_array(); func1(arr1) func2(arr1) } } I need to stop the functions running if they have not ended in 5 minutes. I have thought that I have to put in the functions something like this : void func1(array<array<int,4>,4> initial) { while (5minutes_not_passed) { //do staff if(solution==true) break; } } But I dont know what to put in the 5minutes_not_passed. the declaration of the functions are like this: void func1(array<array<int,4>,4> initial) void func2(array<array<int,4>,4> initial) I have found that I can use the thread library but I dont think meshing up with threads in a good idea. I believe something like a timer is needed. Note that the functions sometimes might end before 5 minutes.

• How do I cache jQuery selections?

  - by David

  I need to cache about 100 different selections for animating. The following is sample code. Is there a syntax problem in the second sample? If this isn't the way to cache selections, it's certainly the most popular on the interwebs. So, what am I missing? note: p in the $.path.bezier(p) below is a correctly declared object passed to jQuery.path.bezier (awesome animation library, by the way) This works $(document).ready(function() { animate1(); animate2(); }) function animate1() { $('#image1').animate({ path: new $.path.bezier(p) }, 3000); setTimeout("animate1()", 3000); } function animate2() { $('#image2').animate({ path: new $.path.bezier(p) }, 3000); setTimeout("animate2()", 3000); } This doesn't work var $one = $('#image1'); //problem with syntax here?? var $two = $('#image2'); $(document).ready(function() { animate1(); animate2(); }) function animate1() { $one.animate({ path: new $.path.bezier(p) }, 3000); setTimeout("animate1()", 3000); } function animate2() { $two.animate({ path: new $.path.bezier(p) }, 3000); setTimeout("animate2()", 3000); }

• How can I bind the same dependency to many dependents in Ninject?

  - by Mike Bantegui

  Let's I have three interfaces: IFoo, IBar, IBaz. I also have the classes Foo, Bar, and Baz that are the respective implementations. In the implementations, each depends on the interface IContainer. So for the Foo (and similarly for Bar and Baz) the implementation might read: class Foo : IFoo { private readonly IDependency Dependency; public Foo(IDependency dependency) { Dependency = dependency; } public void Execute() { Console.WriteLine("I'm using {0}", Dependency.Name); } } Let's furthermore say I have a class Container which happens to contain instances of the IFoo, IBar and IBaz: class Container : IContainer { private readonly IFoo _Foo; private readonly IBar _Bar; private readonly IBaz _Baz; public Container(IFoo foo, IBar bar, IBaz baz) { _Foo = foo; _Bar = bar; _Baz = baz; } } In this scenario, I would like the implementation class Container to bind against IContainer with the constraint that the IDependency that gets injected into IFoo, IBar, and IBaz be the same for all three. In the manual way, I might implement it as: IDependency dependency = new Dependency(); IFoo foo = new Foo(dependency); IBar bar = new Bar(dependency); IBaz baz = new Baz(dependency); IContainer container = new Container(foo, bar, baz); How can I achieve this within Ninject? Note: I am not asking how to do nested dependencies. My question is how I can guarantee that a given dependency is the same among a collection of objects within a materialized service. To be extremely explicit, I understand that Ninject in it's standard form will generate code that is equivalent to the following: IContainer container = new Container(new Foo(new Dependency()), new Bar(new Dependency()), new Baz(new Dependency())); I would not like that behavior.

I found this one pretty easy, but running the file took an extremely long time, it's been going on for a while and the highest number I've got to is 716151937.

• Windows service: Listening on socket while running as LocalSystem

  - by Socob

  I'm writing a small server-like program in C for Windows (using MinGW/GCC, testing on Windows 7) which is eventually supposed to run as a service with the LocalSystem account. I am creating a socket, and using Windows Sockets bind(), listen() and accept() to listen for incoming connections. If I run the application from the command line (i.e. not as a service, but as a normal user), I have no problems connecting to it from external IPs. However, if I run the program as a service with the LocalSystem account, I can only connect to the service from my own PC, either with 127.0.0.1 or my local address, 192.168.1.80 (I'm behind a router in a small local network). Neither external IPs nor other PCs in the same local network, using my local address, can connect now, even though there were no problems without running as a service. Now, I've heard that networking is handled differently or even not accessible (?) when running as LocalSystem or LocalService or that services cannot access both the desktop and the network (note: my service is not interactive) at the same time due to security considerations. Essentially, I need to find out what's going wrong/how to listen for connections in a service. Is running as NetworkService the same as running as LocalSystem, but with network access? Surely there must be servers that can run as background services, so how do they do it?

• How to distribute ranking using MySQL Query and PHP

  - by nkp

  I have to distribute ranking to the 5000 students in an exam. Ranking is based on the score and the time taken (in seconds) to obtain that score. For example is 5 students have same score, then taken will be the criteria to calculate their ranks otherwise score should be the criteria to calculate their ranks. Following is my table tbRank ID StudID Score Time Date Rank 1 11 8 60 09-11-2013 2 22 6 45 09-11-2013 3 33 4 76 09-11-2013 4 44 6 67 09-11-2013 5 55 8 35 09-11-2013 6 66 8 35 08-11-2013 7 77 8 39 08-11-2013 Now rank column in above table should be updated as: ID StudID Score Time Date Rank 1 11 8 60 09-11-2013 2 2 22 6 45 09-11-2013 3 3 33 4 76 09-11-2013 5 4 44 6 67 09-11-2013 4 5 55 8 35 09-11-2013 1 6 66 8 35 08-11-2013 1 7 77 8 39 08-11-2013 2 I want to make a MySQL Query to do this business. Similarly there can be more than 10000 records in the table. So I need an optimized query for this functionality. Note: I am using PHP and MYSQL. Update: Everyday almost 5000 new entries will be created in the table and after all insertions are made, rank column will be updated once in a day. Now please suggest me the best way to do this. If I update rank column in the table, then only once I will have to do it, otherwise everytime while fetching the rank of the student, I will have to make calculations.

• 3D coordinate of 2D point given camera and view plane

  - by Myx

  I wish to generate rays from the camera through the viewing plane. In order to do this, I need my camera position ("eye"), the up, right, and towards vectors (where towards is the vector from the camera in the direction of the object that the camera is looking at) and P, the point on the viewing plane. Once I have these, the ray that's generated is: ray = camera_eye + t*(P-camera_eye); where t is the distance along the ray (assume t = 1 for now). My question is, how do I obtain the 3D coordinates of point P given that it is located at position (i,j) on the viewing plane? Assume that the upper left and lower right corners of the viewing plane are given. NOTE: The viewing plane is not actually a plane in the sense that it doesn't extend infinitely in all directions. Rather, one may think of this plane as a widthxheight image. In the x direction, the range is 0--width and in the y direction the range is 0--height. I wish to find the 3D coordinate of the (i,j)th element, 0

• Calculating percent "x/y * 100" always results in 0?

  - by Patrick Beninga

  In my assignment i have to make a simple version of Craps, for some reason the percentage assignments always produce 0 even when both variables are non 0, here is the code. import java.util.Random; Header, note the variables public class Craps { private int die1, die2,myRoll ,myBet,point,myWins,myLosses; private double winPercent,lossPercent; private Random r = new Random(); Just rolls two dies and produces their some. public int roll(){ die1 = r.nextInt(6)+1; die2 = r.nextInt(6)+1; return(die1 + die2); } The Play method, this just loops through the game. public void play(){ myRoll = roll(); point = 0; if(myRoll == 2 ||myRoll == 3 || myRoll == 12){ System.out.println("You lose!"); myLosses++; }else if(myRoll == 7 || myRoll == 11){ System.out.println("You win!"); myWins++; }else{ point = myRoll; do { myRoll = roll(); }while(myRoll != 7 && myRoll != point); if(myRoll == point){ System.out.println("You win!"); myWins++; }else{ System.out.println("You lose!"); myLosses++; } } } This is where the bug is, this is the tester method. public void tester(int howMany){ int i = 0; while(i < howMany){ play(); i++; } bug is right here in these assignments statements winPercent = myWins/i * 100; lossPercent = myLosses/i* 100; System.out.println("program ran "+i+" times "+winPercent+"% wins "+ lossPercent+"% losses with "+myWins+" wins and "+myLosses+" losses"); } }

• Is there a Twitter Bootstrap class that means "initially hidden"?

  - by bgp

  Using Bootstrap 3, I have an element on a page I want to show later in response to the user clicking a button. Example: <div id="search_results"> ... gets populated from ajax data later ... </div> <button id="search_button" type="button" class="btn btn-primary pull-right">Search</button> <script> $('#search_button').click(function() { // ... do the call to search // and in the callback: $('#search_results').show(); }); </script> The search_results div should be initially hidden. Is there some normal/best practice way of doing this with bootstrap? Yes, I do realize I can just put style="display:none" on search_results, but is that the best way to do it? It would seem to be a bit better to have a style that semantically means "initially hidden". (NOTE: The hidden or hide classes don't do this as they are !important and show(), toggle(), etc. use an inline style which does not override them, i.e. setting "hidden" as the class makes it unshowable from jQuery.)

• Simple syntax question

  - by stabby

  Hey everyone, First off, sorry for my noob-ness. Believe me when i say ive been rtfm'ing. Im not lazy, im just dumb (apparently). On the bright side, this could earn someone some easy points here. I'm trying to do a match/replace with a pattern that contains special characters, and running into syntax errors in a Flex 3 app. I just want the following regex to compile... (while also replacing html tags with "") value.replace(/</?\w+((\s+\w+(\s*=\s*(?:".*?"|'.*?'|[^'">\s]+))?)+\s*|\s*)/?>/g, ""); On a side note, the pattern /<.*?/g wouldn't work in cases where there are html entities between tags, like so: <TEXTFORMAT LEADING="2"> <P ALIGN="LEFT"> <FONT FACE="Arial" SIZE="11" COLOR="#4F4A4A" LETTERSPACING="0" KERNING="0"><one</FONT> </P> </TEXTFORMAT><TEXTFORMAT LEADING="2"> <P ALIGN="LEFT"> <FONT FACE="Arial" SIZE="11" COLOR="#4F4A4A" LETTERSPACING="0" KERNING="0">two</FONT> </P> </TEXTFORMAT> The first regex would get both "<one" and "two", but the second would only get "hi" Thanks!

• Looking for something to add some standard rules for my c++ project.

  - by rkb

  Hello all, My team is developing a C++ project on linux. We use vim as editor. I want to enforce some code standard rules in our team in such a way that if the code is not in accordance with it, some sort of warning or error will be thrown when it builds or compiles. Not necessarily it builds but at least I can run some plugin or tools on that code to make sure it meets the standard. So that before committing to svn everyone need to run the code through some sort of plugin or script and make sure it meets the requirement and then only he/she can commit. Not sure if we can add some rules to vim, if there are any let me know about it. For eg. In our code standards all the member variables and private functions should start with _ class A{ private: int _count; float _amount; void _increment_count(){ ++_count; } } So I want to throw some warning or error or some sort of messages for this class if the variables are declared as follows. class A{ private: int count; float amount; void increment_count(){ ++_count; } } Please note that warning and error are not from compiler becoz program is still valid. Its from the tool I want to use so that code goes to re-factoring but still works fine on the executable side. I am looking for some sort of plugin or pre parsers or scripts which will help me in achieving all this. Currently we use svn; just to anser the comment.

• Accessing global variables in a flash[:notice]

  This is deals_controller.rb. And it works like this, except two things. Not sure how to call Deal.count to add in my flash[:notice] . I get the hunch that its not calling something global. I need that contional statement back, as I'm pretty sure its responsible for actually adding the new @deal . So I assume my syntax is off. Do note, I added an extra 'end' when I uncomment this block. def create -# This will use the disclaimer_ids submitted from the check boxes in the view -# to add/delete deal.disclaimers entries to matched the list of checked boxes. @deal = Deal.new(params[:deal]) -# <------I Need this commented out IF statement back ------- -#if @deal.valid? && @organization.deals << @deal flash[:notice] = 'Your promotion is published!

• Sending a message to nil?

  - by Ryan Delucchi

  As a Java developer who is reading Apple's Objective-C 2.0 documentation: I wonder as to what sending a message to nil means - let alone how it is actually useful. Taking an excerpt from the documentation: There are several patterns in Cocoa that take advantage of this fact. The value returned from a message to nil may also be valid: If the method returns an object, any pointer type, any integer scalar of size less than or equal to sizeof(void*), a float, a double, a long double, or a long long, then a message sent to nil returns 0. If the method returns a struct, as defined by the Mac OS X ABI Function Call Guide to be returned in registers, then a message sent to nil returns 0.0 for every field in the data structure. Other struct data types will not be filled with zeros. If the method returns anything other than the aforementioned value types the return value of a message sent to nil is undefined. Has Java rendered my brain incapable of grokking the explanation above? Or is there something that I am missing that would make this as clear as glass? Note: Yes, I do get the idea of messages/receivers in Objective-C, I am simply confused about a receiver that happens to be nil.

• Having an issue with the "this" modifier...

  - by user344246

  I have this method in City class. It should create a new city based on the object which the method is applied to: public City newCity(string newCityName, int dX, int dY) { City c=new City(this); //based on a constructor : City(City c){} c.CityName=newCityName; c.NoOfNeighborhoods=1; c.NumOfResidents=0; c.CityCenter.Move(dX,dY); return c; } CityCenter is of type "Point" which has two fields - x,y. the Move method in Point class is ment to change the CityCenter location. It looks like this: public void Move(int dX, int dY) { this.X = x + dX; this.Y = y + dY; } What happens is that the new object,c and the existing City object are both changed. I think that "this" modifier works on the existing object too... How can I take advantage of the Move method without causing this behavior? Note: this is a closed API, so I can only add private methods to the project.

• int foo(type& bar); is a bad practice?

  - by Earlz

  Well, here we are. Yet another proposed practice that my C++ book has an opinion on. It says "a returning-value(non-void) function should not take reference types as a parameter." So basically if you were to implement a function like this: int read_file(int& into){ ... } and used the integer return value as some sort of error indicator (ignoring the fact that we have exceptions) then that function would be poorly written and it should actually be like void read_file(int& into, int& error){ } Now to me, the first one is much clearer and nice to use. If you want to ignore the error value, you do so with ease. But this book suggests the later. Note that this book does not say returning value functions are bad. It rather says that you should either only return a value or you should only use references. What are your thoughts on this? Is my book full of crap? (again)

• A better way of handling the below program(may be with Take/Skip/TakeWhile.. or anything better)

  - by Newbie

  I have a data table which has only one row. But it is having 44 columns. My task is to get the columns from the 4th row till the end. Henceforth, I have done the below program that suits my requirement. (kindly note that dt is the datatable) List<decimal> lstDr = new List<decimal>(); Enumerable.Range(0, dt.Columns.Count).ToList().ForEach(i => { if (i > 3) lstDr.Add(Convert.ToDecimal(dt.Rows[0][i])); } ); There is nothing harm in the program. Works fine. But I feel that there may be a better way of handimg the program may be with Skip ot Take or TakeWhile or anyother stuff. I am looking for a better solution that the one I implemented. Is it possible? I am using c#3.0 Thanks.

• How can I call multiple nutrient information from ESHA Research API? (apid.esha.com)

  - by user1833044

  I want to call ESHA Research nutrient REST API. I cannot seem to figure out how to call multiple nutrients using ESHA REST API. So far I am calling the following and only able to retrieve the calories, or protein, or another type of nutrient information. So I was hoping someone had experience in retrieving all the nutrient information with one call. Is this possible? This is how I call to retrieve the TWIX nutrient http://api.esha.com/analysis?apikey=xxxx&fo=urn:uuid:81d268ac-f1dc-4991-98c1-1b4d3a5006da (returns calories, please note the api key is not xxxx but instead a key generated from Esha once you sign up as developer) The return is JSON format. If I want to call fat it would be the following http://api.esha.com/analysis?apikey=xxxx&fo=urn:uuid:81d268ac-f1dc-4991-98c1-1b4d3a5006da&n=urn:uuid:589294dc-3dcc-4b64-be06-c07e7f65c4bd How can I make a call once and get a return of all the nutrients (so Fat, Calories, Carbs, Vitamins, etc..) for a particular food ID? I have researched and looked at this for a while and cannot seem to find the answer. Thanks in advance for your help.

• JPA entity relations are not populated after .persist()

  - by Tomik

  Hello, this is a sample of my two entities: @Entity public class Post implements Serializable { @OneToMany(mappedBy = "post", fetch = javax.persistence.FetchType.EAGER) @OrderBy("revision DESC") public List<PostRevision> revisions; @Entity(name="post_revision") public class PostRevision implements Serializable { @ManyToOne public Post post; private Integer revision; @PrePersist private void prePersist() { List<PostRevision> list = post.revisions; if(list.size() >= 1) revision = list.get(list.size() - 1).revision + 1; else revision = 1; } So, there's a "post" and it can have several revisions. During persisting of the revision, entity takes a look at the list of the existing revisions and finds the next revision number. Problem is that Post.revisions is NULL but I think it should be automatically populated. I guess there's some kind of problem in my source code but I don't know where. Here's my "persistence" code: Post post = new Post(); PostRevision revision = new PostRevision(); revision.post = post; em.persist(post); em.persist(revision); em.flush(); I think that after persisting "post", it becomes "managed" and all the relations should be populated from now on. Thanks for help! (Note: public attributes are just for demonstration)
