  • Manually setting object's position or have the object do it all?

    - by N. Lucas
    I'm stuck thinking about the best way to go about setting a line segment's position, I have a class Line(length, angle, previous) being called from a class Polygon.. Right now I have: public function Line(length:Number, angle:Number, previous:Line = null) { if (previous != null) { this.x = previous.end.x; this.y = previous.end.y; } /**/ } Now, is this the best practice or should I be doing: Polygon.addLine(length:Number, angle:Number):void { var previous = _line[_line.length - 1]; // Array containing all Lines var line:Line = new Line(length, angle, previous); line.x = previous.end.x; line.y = previous.end.y; /**/ }

  • .Net in HTML tp return true if reader object not null, otherwise return false

    - by Phill Healey
    I'm using a DataList to show some data from the database and populating the fields on the html side. I now have a requirement to change the visibility of a panel based on whether or not a db field has data or not. I need to be able to show the panel if the relevant data field has content, and hide it if it doesn't. Eg: <asp:Panel ID="pnlNew" runat="server" Style="margin:0; padding:0; width:42px; height:18px; bottom:5px; right:10px; float:right; position:relative; background:url(../_imgVideoBadge.png) no-repeat;" Visible='<%# Eval("cheese") != null %>' ToolTip="available"></asp:Panel> Obviously this doesn't work in terms of the visible property. But hopefully it gives an idea of what I'm trying to achieve. Any help would be greatly appreciated. I've seen examples previously of doing something along the lines of: a ?? b:c How could this be applied to the above requirement?? Thanks in advance.

  • MVVM and avoiding Monolithic God object

    - by bufferz
    I am in the completion stage of a large project that has several large components: image acquisition, image processing, data storage, factory I/O (automation project) and several others. Each of these components is reasonably independent, but for the project to run as a whole I need at least one instance of each component. Each component also has a ViewModel and View (WPF) for monitoring status and changing things. My question is the safest, most efficient, and most maintainable method of instantiating all of these objects, subscribing one class to an Event in another, and having a common ViewModel and View for all of this. Would it best if I have a class called God that has a private instance of all of these objects? I've done this in the past and regretted it. Or would it be better if God relied on Singleton instances of these objects to get the ball rolling. Alternatively, should Program.cs (or wherever Main(...) is) instantiate all of these components, and pass them to God as parameters and then let Him (snicker) and His ViewModel deal with the particulars of running this projects. Any other suggestions I would love to hear. Thank you!

  • Problem with passing vector of pointers to objects to member function of another object

    - by Jamesz
    Hi, I have a vector of pointers to Mouse objects called 'mice'. I'm passing the mice to the cat by reference. vector <Mouse*> mice; Cat * c; c->lookForMouse(&mice); And here's my lookForMouse() member function void Cat::lookForMouse(vector <Mouse*> *mice) { ... } And now to the problem! Within the function above, I can't seem to access my mice. This below will not work mice[i]->isActive(); The error message I receive suggests to use mice[i].isActive(), but this throws an error saying isActive() is not a member of std::vector<_Ty ... This works though... vector <Mouse*> miceCopy = *mice; miceCopy[i]->isActive(); I understand that I shouldn't be creating another vector of mice here, it defeats the whole point of passing it by reference (let me know if I'm wrong)... Why can't I do mice[i]-isActive() What should I be doing? Thanks for your time and help :D James.

  • WPF Binding not updating when binded object is updated

    - by Chris Klepeis
    I'm trying to bind to a custom control like so: <my:GanttChartTaskListView Name="ganttChartTaskListView1" ItemsSource="{Binding Source={x:Static local:TaskCollection.taskList}}" /> In my WPF Window constructor I add add an item to my taskList, when it loads I can see that item in my custom control, however, when I subsequently add items it does not update. I tried setting Mode=TwoWay, however, then it says the "Path" is required and I'm not familiar with binding like that (this is new to me). Here is my TaskCollection class: namespace ProjectManager { public static class TaskCollection { private static List<TaskItem> _taskList = new List<TaskItem>(); public static List<TaskItem> taskList { get {return _taskList; } set { _taskList = value; } } } } Any ideas? Is there a better / easier way to do this?

  • c++ object sizes

    - by anon
    Suppose I have: struct Foo: public Bar { .... } Foo introduces no new member varaibles. Foo only introduces a bunch of member functions & static functions. Does any part of the C++ standard now guarantee me that: sizeof(Foo) == sizeof(Bar) ? Thanks!

  • Javascript terminates after trying to select data from an object passed to a function

    - by Silmaril89
    Here is my javascript: $(document).ready(function(){ var queries = getUrlVars(); $.get("mail3.php", { listid: queries["listid"], mindex: queries["mindex"] }, showData, 'html'); }); function showData(data) { var response = $(data).find("#mailing").html(); if (response == null) { $("#results").html("<h3>Server didn't respond, try again.</h3>"); } else if (response.length) { var old = $("#results").html(); old = old + "<br /><h3>" + response + "</h3>"; $("#results").html(old); var words = response.split(' '); words[2] = words[2] * 1; words[4] = words[4] * 1; if (words[2] < words[4]) { var queries = getUrlVars(); $.get("mail3.php", { listid: queries["listid"], mindex: words[2] }, function(data){showData(data);}, 'html'); } else { var done = $(data).find("#done").html(); old = old + "<br />" + done; $("#results").html(old); } } else { $("#results").html("<h3>Server responded with an empty reply, try again.</h3>"); } } function getUrlVars() { var vars = [], hash; var hashes = window.location.href.slice(window.location.href.indexOf('?') + 1).split('&'); for (var i = 0; i < hashes.length; i++) { hash = hashes[i].split('='); vars.push(hash[0]); vars[hash[0]] = hash[1]; } return vars; } After the first line in showData: var response = $(data).find("#mailing").html(); the javascript stops. If I put an alert before it, the alert pops up, after it, it doesn't pop up. There must be something wrong with using $(data), but why? Any ideas would be appreciated.

  • How to iterate over every property of an object in javascript?

    - by OverloadUT
    Is there a way to iterate over every property of an object using the Prototype JavaScript framework? Here's the situation: I am getting an AJAX response in JSON that looks something like this: {foo: 1, bar: 2, barobj: {75: true, 76: false, 85: true}} If I evaluate that json response in to a variable response, I want to be able to iterate over each property in the response.barobj object to see which indexes are true and which are false. Prototype has both Object.keys() and Object.values() but oddly seems to not have a simple Object.each() function! I could take the results of Object.keys() and Object.values() and cross-reference the other as I iterate through one, but that is such a hack that I am sure there is a proper way to do it!

  • Serialization of an object and its Contained Objects

    - by Amit
    There is a main class having 2 subClasses(each represent separate entity) and all classes needs to be serialized.. how should I proceed ? My requirement is when I serelize MainClass, I should get the xml for each sub class and main class as well. Thanks in advance... and if my approach is incorrect... correct that as well.. Ex given below... class MainClass { SubClass1 objSubclass1 = null; SubClass2 objSubclass2 = null; public MainClass() { objSubclass1 = new SubClass1(); objSubclass2 = new SubClass2(); } [XmlElement("SubClass1")] public SubClass1 SubClass1 {get {return objSubclass1;} } [XmlElement("SubClass2")] public SubClass2 SubClass2 {get {return objSubclass2;} } } Class SubClass1 { Some properties here... } Class SubClass2 { Some properties here... }

  • Creating an object in the loop

    - by Jacob
    std::vector<double> C(4); for(int i = 0; i < 1000;++i) for(int j = 0; j < 2000; ++j) { C[0] = 1.0; C[1] = 1.0; C[2] = 1.0; C[3] = 1.0; } is much faster than for(int i = 0; i < 1000;++i) for(int j = 0; j < 2000; ++j) { std::vector<double> C(4); C[0] = 1.0; C[1] = 1.0; C[2] = 1.0; C[3] = 1.0; } I realize this happens because std::vector is repeatedly being created and instantiated in the loop, but I was under the impression this would be optimized away. Is it completely wrong to keep variables local in a loop whenever possible? I was under the (perhaps false) impression that this would provide optimization opportunities for the compiler. EDIT: I use VC++2005 (release mode) with full optimization (/Ox)
