  • Javascript: sort objects

    - by tom
    function Player() { var score; this.getScore = function() { return score; } this.setScore = function(sc) { score = sc; } } function compare(playerA, playerB) { return playerA.getScore() - playerB.getScore(); } var players = []; players['player1'] = new Player(); players['player2'] = new Player(); Array(players).sort(compare); I have code that is similar to the above. When I step through the code with a debugger, the compare function never gets called and the array isn't sorted. I'm not sure what's wrong with my code?

  • JSONP & jQuery Chunking

    - by Tom
    Hi Guys, I am wanting to utilize JSONP for a project with x-domain scripting but little concerned with the 2048 character limit in IE. Does JSONP support "chunking" automatically if character size exceeds 2048 ? If yes, does anyone have any examples they can share ? Thx

  • C++ design question, container of instances and pointers

    - by Tom
    Hi all, Im wondering something. I have class Polygon, which composes a vector of Line (another class here) class Polygon { std::vector<Line> lines; public: const_iterator begin() const; const_iterator end() const; } On the other hand, I have a function, that calculates a vector of pointers to lines, and based on those lines, should return a pointer to a Polygon. Polygon* foo(Polygon& p){ std::vector<Line> lines = bar (p.begin(),p.end()); return new Polygon(lines); } Here's the question: I can always add a Polygon (vector Is there a better way that dereferencing each element of the vector and assigning it to the existing vector container? //for line in vector<Line*> v //vcopy is an instance of vector<Line> vcopy.push_back(*(v.at(i)) I think not, but I dont really like that approach. Hopefully, I will be able to convince the author of the class to change it, but I cant base my coding right now to that fact (and i'm scared of a performance hit). Thanks in advance.

  • SQL Server 2005 Weird varchar Behavior

    - by Tom Tresansky
    This SQL Server 2005 T-SQL code: DECLARE @Test1 varchar; SET @Test1 = 'dog'; DECLARE @Test2 varchar(10); SET @Test2 = 'cat'; SELECT @Test1 AS Result1, @Test2 AS Result2; produces: Result1 = d Result2 = cat I would expect either The assignment SET @Test1 = 'dog'; to fail because there isn't enough room in @Test1 Or the SELECT to return 'dog' in the Result1 column. What is up with @Test1? Could someone please explain this behavior?

  • C++ vector<T>::iterator operator +

    - by Tom
    Hi, Im holding an iterator that points to an element of a vector, and I would like to compare it to the next element of the vector. Here is what I have Class Point{ public: float x,y; } //Somewhere in my code I do this vector<Point> points = line.getPoints(); foo (points.begin(),points.end()); where foo is: void foo (Vector<Point>::iterator begin,Vector<Point>::iterator end) { std::Vector<Point>::iterator current = begin; for(;current!=end-1;++current) { std::Vector<Point>::iterator next = current + 1; //Compare between current and next. } } I thought that this would work, but current + 1 is not giving me the next element of the vector. I though operator+ was the way to go, but doesnt seem so. Is there a workaround on this? THanks

  • AES Key encoded byte[] to String and back to byte[]

    - by Tom Brito
    In the similar question "Conversion of byte[] into a String and then back to a byte[]" is said to not to do the byte[] to String and back conversion, what looks like apply to most cases, mainly when you don't know the encoding used. But, in my case I'm trying to save to a DB the javax.crypto.SecretKey data, and recoverd it after. The interface provide a method getEncoded() which returns the key data encoded as byte[], and with another class I can use this byte[] to recover the key. So, the question is, how do I write the key bytes as String, and later get back the byte[] to regenerate the key?

  • TextBox loses text when InvokeRequired == false

    - by Tom
    This is modified code I found on this site. When appending text to a TextBox and InvoveRequired is false the text will display in the box but the next time the function is called and InvokeRequired is true the text string placed by the first call is lost (""). Multiple calls when InvokeRequired is true work as expected. comBox is a type TextBox with multline = true. Any help would be appreciated. public void LogComText(string comText, bool newline) { if (comBox.InvokeRequired) { comBox.BeginInvoke(new Action(delegate { LogComText(comText, newline); })); return; } comBox.AppendText(comText); if (newline) comBox.AppendText(Environment.NewLine); }

How can I get around this prob ?

  • WindowsFormsApplicationBase SplashScreen makes login form ignore keypresses until I click on it - how to debug?

    - by Tom Bushell
    My WinForms app has a simple modal login form, invoked at startup via ShowDialog(). When I run from inside Visual Studio, everything works fine. I can just type in my User ID, hit the Enter key, and get logged in. But when I run a release build directly, everything looks normal (the login form is active, there's a blinking cursor in the User ID MaskedEditBox), but all keypresses are ignored until I click somewhere on the login form. Very annoying if you are used to doing everything from the keyboard. I've tried to trace through the event handlers, and to set the focus directly with code, to no avail. Any suggestions how to debug this (outside of Visual Studio), or failing that - a possible workaround? Edit Here's the calling code, in my Main Form: private void OfeMainForm_Shown(object sender, EventArgs e) { OperatorLogon(); } private void OperatorLogon() { // Modal dialogs should be in a "using" block for proper disposal using (var logonForm = new C21CfrLogOnForm()) { var dr = logonForm.ShowDialog(this); if (dr == DialogResult.OK) SaveOperatorId(logonForm.OperatorId); else Application.Exit(); } } Edit 2 Didn't think this was relevant, but I'm using Microsoft.VisualBasic.ApplicationServices.WindowsFormsApplicationBase for it's splash screen and SingleInstanceController support. I just commented out the splash screen code, and the problem has disappeared. So that's opened up a whole new line of inquiry... Edit 3 Changed title to reflect better understanding of the problem

  • Using Selenium to Determining The Visibility of Elements for Print media

    - by Tom Howard
    I would like to determine if particular elements on a page are visible when printed as controlled by CSS @media rules. Is there a way to do this with Selenium? I know there is the isDisplayed method, which takes the CSS into account, but there is nothing I can find to tell Selenium which media type to apply. Is there a way to do this? Or is there another way to test web pages to make sure the elements you want are printed (and those you don't aren't)? Update: For clarity, there are no plans to have a javascript print button. The users will print using the normal print functionality of the browser (Chrome, FF and IE). @media css rules will be used to control what is shown and hidden. I would like Selenium to pretend it is a printer instead of a screen, so I can test if certain elements will be visible in what would be the printed version of the page.

  • PHP: Opening/closing tags & performance?

    - by Tom
    Hi, This may be a silly question, but as someone relatively new to PHP, I'm wondering if there are any performance-related issues to frequently opening and closing PHP tags in HTML template code, and if so, what might be best practices in terms of working with php tags? My question is not about the importance/correctness of closing tags, or about which type of code is more readable than another, but rather about how the document gets parsed/executed and what impact it might have on performance. To illustrate, consider the following two extremes: Mixing PHP and HTML tags: <?php echo '<tr> <td>'.$variable1.'</td> <td>'.$variable2.'</td> <td>'.$variable3.'</td> <td>'.$variable4.'</td> <td>'.$variable5.'</td> </tr>' ?> // PHP tag opened once Separating PHP and HTML tags: <tr> <td><?php echo $variable1 ?></td> <td><?php echo $variable2 ?></td> <td><?php echo $variable3 ?></td> <td><?php echo $variable4 ?></td> <td><?php echo $variable5 ?></td> </tr> // PHP tag opened five times Would be interested in hearing some views on this, even if it's just to hear that it makes no difference. Thanks.

  • C++ Adding 2 arrays together quickly

    - by Tom Gullen
    Hello! Given the arrays: int canvas[10][10]; int addon[10][10]; Where all the values range from 0 - 100, what is the fastest way in C++ to add those two arrays so each cell in canvas equals itself plus the corresponding cell value in addon. IE, I want to achieve something like: canvas += another; So if canvas[0][0] =3 and addon[0][0] = 2 then canvas[0][0] = 5 Speed is essential here as I am writing a very simple program to brute force a knapsack type problem and there will be tens of millions of combinations.

  • Symfony 1.4: Deleting a sfGuardUser

    - by Tom
    Hi, I'm having some trouble with the following... I have a sfGuardUser table set up normally, and it has a one-to-one relationship with a Profile table, which contains some additional user info. When a user wants to delete themselves from the site, I'd like to retain their info in the Profile table for various purposes BUT delete the sfGuardUser in order to keep that table cleaner/shorter (not just set it to inactive). I was under the impression that I could set the FK in the Profile table to NULL and then delete the sfGuardUser, but it seems the FK-constraint fails. Indeed, it seems I can't delete either and the queries fail: If I try to delete the sfGuardUser, the Profile table will have an invalid FK If I try to delete a Profile, the sfGuardUser will have an invalid FK Other than leaving outdated sfGuardUsers and Profiles in these tables, or having to use a cascaded delete to get rid of both, can anyone tell me if there's any other way around this? Thank you.

  • Referencing control on one form from another form VB.NET

    - by Tom
    My gosh man, why is this so complicated in VB.NET? As you can guess, I'm kind of new to .NET and just want to reference a control on one form from another. Usually I would just do Form.Control.Property but that doesn't work and every example I've found through Google doesn't work for me. It just seems overly complicated with public classes, etc. Is there a more simpler way to do this? I'm ready to throw in the towel and just use a global variable at this point. I have the form containing the control I want to reference, frmGenerate which has a textbox called txtCustomerNo. From this form through a button's click event I want to show another form, frmCustomers, and have that form reference the value in txtCustomerNo. frmCustomers.ShowDialog() It has to be something simple that I'm just not grasping. Thanks.

  • Learning to implement DIC in MVC

    - by Tom
    I am learning to apply DIC to MVC project. So, I have sketched this DDD-ish DIC-ready-ish layout to my best understanding. I have read many blogs articles wikis for the last few days. However, I am not confident about implementing it correctly. Could you please demonstrate to me how to put them into DIC the proper way? I prefer Ninject or Windsor after all the readings, but anyDIC will do as long as I can get the correct idea how to do it. Web controller... public class AccountBriefingController { //create private IAccountServices accountServices { get; set; } public AccountBriefingController(IAccountServices accsrv) accountServices = accsrv; } //do work public ActionResult AccountBriefing(string userid, int days) { //get days of transaction records for this user BriefingViewModel model = AccountServices.GetBriefing(userid, days); return View(model); } } View model ... public class BriefingViewModel { //from user repository public string UserId { get; set; } public string AccountNumber {get; set;} public string FirstName { get; set; } public string LastName { get; set; } //from account repository public string Credits { get; set; } public List<string> Transactions { get; set; } } Service layer ... public interface IAccountServices { BriefingViewModel GetBriefing(); } public class AccountServices { //create private IUserRepository userRepo {get; set;} private IAccountRepository accRepo {get; set;} public AccountServices(UserRepository ur, AccountRepository ar) { userRepo = ur; accRepo = ar; } //do work public BriefingViewModel GetBriefing(string userid, int days) { var model = new BriefingViewModel(); //<---is that okay to new a model here?? var user = userRepo.GetUser(userid); if(user != null) { model.UserId = userid; model.AccountNumber = user.AccountNumber; model.FirstName = user.FirstName; model.LastName = user.LastName; //account records model.Credits = accRepo.GetUserCredits(userid); model.Transactions = accRepo.GetUserTransactions(userid, days); } return model; } } Domain layer and data models... public interface IUserRepository { UserDataModel GetUser(userid); } public interface IAccountRepository { List<string> GetUserTransactions(userid, days); int GetUserCredits(userid); } // Entity Framework DBContext goes under here Please point out if my implementation is wrong, e.g.I can feel in AccountServices-GetBriefing - new BriefingViewModel() seems wrong to me, but I don't know how to fit the stud into DIC? Thank you very much for your help!

  • Get a list of events owned by a facebook page

    - by Tom Wright
    Does anyone know how I can get a list of events owned (created) by a Facebook page? I seem to be able to use the "graph api" to generate a list of the events an entity is attending. I also looked at FQL, but it seems to require that the 'where' clause is an indexable field (and, naturally, the id is the only indexable field). For bonus points, we'd be able to do this without any authentication. (Though I'm resigned to the fact that I'm likely going to need at least a permanent access_token.) If anyone know how to do this I'd be eternally grateful.

  • Complicated .NET factory design

    - by Tom W
    Hello SO; I'm planning to ask a fairly elaborate question that is also something of a musing here, so bear with me... I'm trying to design a factory implementation for a simulation application. The simulation will consist of different sorts of entities i.e. it is not a homogenous simulation in any respect. As a result, there will be numerous very different concrete implementations and only the very general properties will be abstracted at the top level. What I'd like to be able to do is create new simulation entities by calling a method on the model with a series of named arguments representing the parameters of the entity, and have the model infer what type of object is being described by the inbound parameters (from the names of the parameters and potentially the sequence they occur in) and call a factory method on the appropriate derived class. For example, if I pass the model a pair of parameters (Param1=5000, Param2="Bacon") I would like it to infer that the names Param1 and Param2 'belong' to the class "Blob1" and call a shared function "getBlob1" with named parameters Param1:=5000, Param2:="Bacon" whereas if I pass the model (Param1=5000, Param3=50) it would call a similar factory method for Blob2; because Param1 and Param3 in that order 'belong' to Blob2. I foresee several issues to resolve: Whether or not I can reflect on the available types with string parameter names and how to do this if it's possible Whether or not there's a neat way of doing the appropriate constructor inference from the combinatoric properties of the argument list or whether I'm going to have to bodge something to do it 'by hand'. If possible I'd like the model class to be able to accept parameters as parameters rather than as some collection of keys and values, which would require the model to expose a large number of parametrised methods at runtime without me having to code them explicitly - presumably one for every factory method available in the relevant namespace. What I'm really asking is how you'd go about implementing such a system, rather than whether or not it's fundamentally possible. I don't have the foresight or experience with .NET reflection to be able to figure out a way by myself. Hopefully this will prove an informative discussion.
