  • Which plugin framework to use for native C++/Win32

    - by Kerido
    Hi everybody. I have an extensible product that allows 3rd party developers to extend it. The aspects that can be extended are documented and interfaces are provided in the SDK. Currently, I'm using COM and I'm getting pretty comfortable with it. I especially like the ability to provide interface versioning in a unified manner. I consider it to be a requirement because you never know what you're gonna need in the future. Just to be precise, here's an example. Let's suppose I have an interface representing a particular feature: class IFeature { public: virtual void DoFeatureTask() = 0; }; Then after the interface is already documented (and someone may have used it in the plugin code) I'm realizing, I need more from this feature. Maybe, there is an option I need to provide. I just define the second version: class IFeature2 { public: virtual void DoFeatureTask(int theOption) = 0; }; I don't mean I intend to have lots of versions. But it just may happen. In COM, because every interface is associated with a GUID, I can query a preferred implementation, determine its presence, and, finally, fall back to a legacy one. But after glancing through C++/COM-related questions, I noticed many recommendations against COM. So maybe it's not the best choice and I'm just too old-school. Can you advise on an alternative?

  • Regex replace (in Python) - a more simple way?

    - by Evan Fosmark
    Any time I want to replace a piece of text that is part of a larger piece of text, I always have to do something like: "(?P<start>some_pattern)(?P<replace>foo)(?P<end>end)" And then concatenate the start group with the new data for replace and then the end group. Is there a better method for this?

  • Simple IF statement question

    - by JGreig
    How can I simply the below if statements? if ( isset(var1) & isset(var2) ) { if ( (var1 != something1) || (var2 != something2) ) { // ... code ... } } Seems like this could be condensed to only one IF statement but am not certain if I'd use an AND or OR

  • SQL simple selection of rows according to their time

    - by iracema78280
    Hello, I have a table with measures and the time this measures have been taken in the following form: MM/DD/YYYY HH:MI:SS AM. I have measures over many days starting at the same time every day.The datas are minute by minute so basically the seconds are always = 0. I want to select only the measures for the first 5 minutes of each day. I would have used the where statement but the condition would only be on the minutes and note the date is there a way to do this? Thanks

  • Translate from Java to C#: simple code to re-encode a string

    - by Dr. Zim
    We were sent this formula to encrypt a string written in Java: String myInput = "test1234"; MessageDigest md = MessageDigest.getInstance("SHA"); byte[] myD = md.digest(myInput.getBytes()); BASE64Encoder en64 = new BASE64Encoder(); String myOutput = new String ( Java.net.URLEncoder.encode( en64.encode(myD))); // myOutput becomes "F009U%2Bx99bVTGwS3cQdHf%2BJcpCo%3D" Our attempt at writing this in C# is: System.Security.Cryptography.SHA1 sha1 = new System.Security.Cryptography.SHA1CryptoServiceProvider(); string myOutput = HttpUtility.UrlEncode( Convert.ToBase64String( sha1.ComputeHash( ASCIIEncoding.Default.GetBytes(myInput)))); However the output is no where near the same. It doesn't even have percent signs in it. Any chance anyone would know where we are going wrong?

  • Backbone events not firing (this.el undefined) & general feedback on use of the framework

    - by Leo
    I am very new to backbone.js and I am struggling a little. I figured out a way to get data from the server (in json) onto the screen successfully but am I doing it the right/best way? I know there is something wrong because the only view which contains a valid this.el is the parent view. I suspect that because of this, the events of the view are not firing ()... What is the best way forward? Here is the code: var surveyUrl = "/api/Survey?format=json&callback=?"; $(function () { AnswerOption = Backbone.Model.extend({}); AnswerOptionList = Backbone.Collection.extend({ initialize: function (models, options) { this.bind("add", options.view.render); } }); AnswerOptionView = Backbone.View.extend({ initialize: function () { this.answerOptionList = new AnswerOptionList(null, { view: this }); _.bindAll(this, 'render'); }, events: { "click .answerOptionControl": "updateCheckedState" //does not fire because there is no this.el }, render: function (model) { // Compile the template using underscore var template = _.template($("#questionAnswerOptionTemplate").html(), model.answerOption); $('#answerOptions' + model.answerOption.questionId + '>fieldset').append(template); return this; }, updateCheckedState: function (data) { //never hit... } }); Question = Backbone.Model.extend({}); QuestionList = Backbone.Collection.extend({ initialize: function (models, options) { this.bind("add", options.view.render); } }); QuestionView = Backbone.View.extend({ initialize: function () { this.questionlist = new QuestionList(null, { view: this }); _.bindAll(this, 'render'); }, render: function (model) { // Compile the template using underscore var template = _.template($("#questionTemplate").html(), model.question); $("#questions").append(template); //append answers using AnswerOptionView var view = new AnswerOptionView(); for (var i = 0; i < model.question.answerOptions.length; i++) { var qModel = new AnswerOption(); qModel.answerOption = model.question.answerOptions[i]; qModel.questionChoiceType = ChoiceType(); view.answerOptionList.add(qModel); } $('#questions').trigger('create'); return this; } }); Survey = Backbone.Model.extend({ url: function () { return this.get("id") ? surveyUrl + '/' + this.get("id") : surveyUrl; } }); SurveyList = Backbone.Collection.extend({ model: Survey, url: surveyUrl }); aSurvey = new Survey({ Id: 1 }); SurveyView = Backbone.View.extend({ model: aSurvey, initialize: function () { _.bindAll(this, 'render'); this.model.bind('refresh', this.render); this.model.bind('change', this.render); this.model.view = this; }, // Re-render the contents render: function () { var view = new QuestionView(); //{el:this.el}); for (var i = 0; i < this.model.attributes[0].questions.length; i++) { var qModel = new Question(); qModel.question = this.model.attributes[0].questions[i]; view.questionlist.add(qModel); } } }); window.App = new SurveyView(aSurvey); aSurvey.fetch(); }); -html <body> <div id="questions"></div> <!-- Templates --> <script type="text/template" id="questionAnswerOptionTemplate"> <input name="answerOptionGroup<%= questionId %>" id="answerOptionInput<%= id %>" type="checkbox" class="answerOptionControl"/> <label for="answerOptionInput<%= id %>"><%= text %></label> </script> <script type="text/template" id="questionTemplate"> <div id="question<%=id %>" class="questionWithCurve"> <h1><%= headerText %></h1> <h2><%= subText %></h2> <div data-role="fieldcontain" id="answerOptions<%= id %>" > <fieldset data-role="controlgroup" data-type="vertical"> <legend> </legend> </fieldset> </div> </div> </script> </body> And the JSON from the server: ?

  • Writing a simple incrementing counter in rails

    - by Trip
    For every Card, I would like to attach a special number to them that increments by one. I assume I can do this all in the controller. def create @card = Card.new(params[:card]) @card.SpecNum = @card.SpecNum ++ ... end Or. I can be blatantly retarded. And maybe the best bet is to add an auto-incremement table to mysql. The problem is the number has to start at a specific number, 1020. Any ideas?

  • Any simple way to "resize" an NSBezierPath?

    - by d11wtq
    I have an NSBezierPath that I'm filling and stroking. I'd like to add some inner glow to the path (a light stroke, just inside of the outer stroke), and the thing that comes to mind is to use the same path shrunk by 1 pixel (the size of the line that is already )stroked. Is there a way to do this? Alternatively, is there some sort of pattern I can use when applying both a border (stroke) and a glow to a bezier path? Example, the (extremely subtle) inner glow on the Google Chrome tabs:

  • Simple startup on boot of misc application (Java based) on Ubuntu Linux 8+ as a daemon

    - by Berlin Brown
    What is the easiest way to have an application launch at startup on Ubuntu server as daemon? This is a java application (java com.run.run.Run) etc. How would I have it launch as a user and possibly have access to write to some log file where the user has permissions to write? And if I don't end up doing that, how would I launch the application as the root user at startup. Edited: It is a headless server, I don't have access to the desktop applications.

  • What tool/framework to use for technical documentation?

    - by Pangea
    We develop products and frameworks to be used with in our organization. I am looking for programmer friendly documentation tools. I have researched on few options sometime back but couldn't decide which one to use. I am looking for suggestions from the people who already used these tools. docbook: springframework and hibernate use this format and this looks good. but I believe they have customized the default xslt/stylesheet. Can I copy and use their xslt and css (ofcourse with colors and images changed). Can I integrate the doc generation using maven? wiki: this is not friendly to the technical document writers and the documentation doesn't look professional. versioning is also not possible I believe word docs: this is what we use currently but it is hard to link and reuse common documents. DITA?

  • Powershell and some simple string manipulation

    - by Pat
    need some help with building a powershell script to help with some basic string manipulation. I know just enough powershell to get in trouble, but can't figure out the syntax or coding to make this work. I have a text file that looks like this - Here is your list of servers: server1 server2.domain.local server3 Total number of servers: 3 I need to take that text file and drop the first and last lines (Always first and last.) Then I need to take every other line and basically turn it into a CSV file. The final output should be a text file that looks like this - server1,server2.domain.local,server3 Any suggestions on where to start? Thanks!

  • DNS Lookup in simple C#/asp.net ajax call is extremely slow

    - by Ryan
    I'm running this out of the VS 2008 debugger on Windows 7, running .Net 3.5. The idea was to make all ajax requests with jQuery only, rather than .net, following some tutorials online. Default.aspx - HTML page, jquery triggers method in Default.aspx.cs http://pastebin.com/pxBvKA2H Default.aspx.cs - C# Webform, just defines a GetDate fuction, which only returns a string for now (trying to eliminate any possible issues) (can only post one hyperlink...) pastebin.com/pnHn50hu The ajax query takes longer than it should. Profiling with firebug revealed that it took 1.03 ms. 1s DNS Lookup | 26ms Waiting | 1ms Receiving EDIT: It continues to take the same set of times if you continue to click and resubmit the request. Is there anything I can do to cut down on the DNS Lookup time / what did I do wrong? Thanks for any help.

  • Simple Self Join Query Bad Performance

  • Interface injection in Spring Framework

    - by Aubergine
    There is article in here, however I am still in doubt, as some people keep confusing me. Doesn't Spring really support Interface injection at all? So what I want to clarify: setSomething(somethingInterface something); // this IS NOT interface injection, IT IS setter injection? Interface injection is when you just write `implements someExportedModuleInterface' and it configures it automatically? Could you please give an example of how this interface injection is done with Spring 'aware' interfaces? I am writing dissertation and I want to be sure what I am saying is not lie and correct.

  • Discrete event simulation framework for .NET

    - by Kuba
    Does anyone have an experience with some discrete event simulation library that could be used in .NET (C#)? Despite the basic functionality for queing events and dispatching them, it would be fine to have some non-deterministic behavior (e.g. failures simulation). I have some tips and I am even considering to write my own, but first, I would like to collect some recomendations. Thanks. Additional info: i'm not looking explicitly for free product, however, the prize matters :) Just to precise the field i need to map, here is the example of a product: http://www.holushko.com/index.html
