  • Getting Service Tag from Dell Machine using .net?

    - by JonH
    Hello folks I've got a class that pulls model information (hardware info) for a local machine code is like so: Imports System.Management Public Class clsWMI Private objOS As ManagementObjectSearcher Private objCS As ManagementObjectSearcher Private objMgmt As ManagementObject Private m_strComputerName As String Private m_strManufacturer As String Private m_StrModel As String Private m_strOSName As String Private m_strOSVersion As String Private m_strSystemType As String Private m_strTPM As String Private m_strWindowsDir As String Public Sub New() objOS = New ManagementObjectSearcher("SELECT * FROM Win32_OperatingSystem") objCS = New ManagementObjectSearcher("SELECT * FROM Win32_ComputerSystem") For Each objMgmt In objOS.Get m_strOSName = objMgmt("name").ToString() m_strOSVersion = objMgmt("version").ToString() m_strComputerName = objMgmt("csname").ToString() m_strWindowsDir = objMgmt("windowsdirectory").ToString() Next For Each objMgmt In objCS.Get m_strManufacturer = objMgmt("manufacturer").ToString() m_StrModel = objMgmt("model").ToString() m_strSystemType = objMgmt("systemtype").ToString m_strTPM = objMgmt("totalphysicalmemory").ToString() Next End Sub Public ReadOnly Property ComputerName() Get ComputerName = m_strComputerName End Get End Property Public ReadOnly Property Manufacturer() Get Manufacturer = m_strManufacturer End Get End Property Public ReadOnly Property Model() Get Model = m_StrModel End Get End Property Public ReadOnly Property OsName() Get OsName = m_strOSName End Get End Property Public ReadOnly Property OSVersion() Get OSVersion = m_strOSVersion End Get End Property Public ReadOnly Property SystemType() Get SystemType = m_strSystemType End Get End Property Public ReadOnly Property TotalPhysicalMemory() Get TotalPhysicalMemory = m_strTPM End Get End Property Public ReadOnly Property WindowsDirectory() Get WindowsDirectory = m_strWindowsDir End Get End Property End Class Any possibility to get a service tag from WMI ?

  • Hudson: how do i use a parameterized build to do svn checkout and svn tag?

    - by Derick Bailey
    I'm setting up a parameterized build in hudson v1.362. the parameter i'm creting is used to determine which branch to checkout in subversion. I can set my svn repository url like this: https://my.svn.server/branches/${branch} and it does the checkout and the build just fine. now I want to tag the build after it finishes. i'm using the SVN tagging plugin for hudson to do this. so i go to the bottom of the project config screen for the hudson project and turn on "Perform Subversion tagging on successful build". here, i set my Tag Base URL to https://my.svn.server/tags/${branch}-${BUILD_NUMBER} and it gives me errors about those properties not being found. so i change them to environment variable usages like this: https://my.svn.server/tags/${env['branch']}-${env['BUILD_NUMBER']} and the svn tagging plugin is happy. the problem now is that my svn repository at the top is using the ${branch} syntax and the svn tagging plugin barfs on this: moduleLocation: Remote -https://my.svn.server/branches/$branch/ Tag Base URL: 'https://my.svn.server/tags/thebranchiused-1234'. There was no old tag at https://my.svn.server/tags/thebranchiused-1234. ERROR: Publisher hudson.plugins.svn_tag.SvnTagPublisher aborted due to exception java.lang.NullPointerException at hudson.plugins.svn_tag.SvnTagPlugin.perform(SvnTagPlugin.java:180) at hudson.plugins.svn_tag.SvnTagPublisher.perform(SvnTagPublisher.java:79) at hudson.tasks.BuildStepMonitor$3.perform(BuildStepMonitor.java:36) at hudson.model.AbstractBuild$AbstractRunner.perform(AbstractBuild.java:601) at hudson.model.AbstractBuild$AbstractRunner.performAllBuildSteps(AbstractBuild.java:580) at hudson.model.AbstractBuild$AbstractRunner.performAllBuildSteps(AbstractBuild.java:558) at hudson.model.Build$RunnerImpl.cleanUp(Build.java:167) at hudson.model.Run.run(Run.java:1295) at hudson.model.FreeStyleBuild.run(FreeStyleBuild.java:46) at hudson.model.ResourceController.execute(ResourceController.java:88) at hudson.model.Executor.run(Executor.java:124) Finished: FAILURE notice the first line, there: the svn tag is looking at ${branch} as part of the repository url... it's not parsing out the property value. i tried to change my original Repository URL for svn to use the ${env['branch']} syntax, but that blows up on the original checkout because this syntax is not getting parsed at all by the checkout. help?! how do i use a parameterized build to set the svn url for checkout and for tagging my build?!

  • Java Swing MVC question

    - by juFo
    I'm following this MVC model: http://java.sun.com/developer/technicalArticles/javase/mvc/ In my model I have an "ArrayList shapes" field and I need the shapes in my view. Is the only way of getting my shapes by getting them in the modelPropertyChange method? public void modelPropertyChange(PropertyChangeEvent evt) { if (evt.getPropertyName().equals(MyController.PROPERTY_TEXT)) { ArrayList<Shape> shapes = (ArrayList<Shape>) evt.getNewValue(); } } or should I also create a generic getter method in my controller? like this generic setter method: protected void setModelProperty(String propertyName, Object newValue) { for (AbstractModel model: registeredModels) { try { Method method = model.getClass(). getMethod("set"+propertyName, new Class[] { newValue.getClass() } ); method.invoke(model, newValue); } catch (Exception ex) { // Handle exception. } } } If I need such a generic getter method, I have no clue how to transform this generic setter above to a generic getter method. If I don't need such a generic getter method to retreive my data from the model, if I only need the modelPropertyChange method from my View. How would I get my data from the model the first time the application starts? :o Pfft I need to get my arraylist of shapes from my model in my view :( (and later I need to get some other data also) So confusing :(

  • Django tests failing on invalid keyword argument

    - by Darwin Tech
    I have a models.py like so: from django.db import models from django.contrib.auth.models import User from datetime import datetime class UserProfile(models.Model): user = models.OneToOneField(User) def __unicode__(self): return self.user.username class Project(models.Model): user = models.ForeignKey(UserProfile) created = models.DateTimeField(auto_now_add=True) updated = models.DateTimeField(auto_now=True) product = models.ForeignKey('tool.product') module = models.ForeignKey('tool.module') model = models.ForeignKey('tool.model') zipcode = models.IntegerField(max_length=5) def __unicode__(self): return unicode(self.id) And my tests.py: from django.test import TestCase, Client # --- import app models from django.contrib.auth.models import User from tool.models import Module, Model, Product from user_profile.models import Project, UserProfile # --- unit tests --- # class UserProjectTests(TestCase): fixtures = ['admin_user.json'] def setUp(self): self.product1 = Product.objects.create( name='bar', ) self.module1 = Module.objects.create( name='foo', enable=True ) self.model1 = Model.objects.create( module=self.module1, name='baz', enable=True ) self.user1 = User.objects.get(pk=1) ... def test_can_create_project(self): self.project1 = Model.objects.create( user=self.user1, product=self.product1, module=self.module1, model=self.model1, zipcode=90210 ) self.assertEquals(self.project1.zipcode, 90210) But I get a TypeError: 'product' is an invalid keyword argument for this function error. I'm not sure what is failing but I'm guessing something to do with the FK relationships... Any help would be much appreciated.

  • MVC.NET custom validator is not working

    - by IvanMushketyk
    I want to write a custom validator for MVC.NET framework that checks if entered date is in the future. To do it, I wrote the following class: [AttributeUsage(AttributeTargets.Property, AllowMultiple = false, Inherited = true)] public sealed class InTheFutureAttribute : ValidationAttribute, IClientValidatable { private const string DefaultErrorMessage = "{0} should be date in the future"; public InTheFutureAttribute() : base(DefaultErrorMessage) { } public override string FormatErrorMessage(string name) { return string.Format(ErrorMessageString, name); } public override bool IsValid(object value) { DateTime time = (DateTime)value; if (time < DateTime.Now) { return false; } return true; } public IEnumerable<ModelClientValidationRule> GetClientValidationRules(ModelMetadata metadata, ControllerContext context) { var clientValidationRule = new ModelClientValidationRule() { ErrorMessage = FormatErrorMessage(metadata.GetDisplayName()), ValidationType = "wrongvalue" }; return new[] { clientValidationRule }; } } and added attribute to field that I want to check. On the View page I create input field in the following way: <div class="editor-label-search"> @Html.LabelFor(model => model.checkIn) </div> <div class="editor-field-search-date"> @Html.EditorFor(model => model.checkIn) <script type="text/javascript"> $(document).ready(function () { $('#checkIn').datepicker({ showOn: 'button', buttonImage: '/Content/images/calendar.gif', duration: 0, dateFormat: 'dd/mm/yy' }); }); </script> @Html.ValidationMessageFor(model => model.checkIn) </div> When I submit the form for the controller that requires model with checked attribute code in my validator is called and it returns false, but instead of displaying an error it just call my controller's action and send invalid model to it. Am I doing something wrong? How can I fix it? Thank you in advance.

  • Use Hudson Build Parameter in Grails Build Target

    - by Stephen Swensen
    I have created two Hudson String Parameters in my parametrized build configuration: svnRoot, and svnBranch. I can reference these just fine when specifying my Repository URL: ${svnRoot}/${svnBranch}/subProject. But I have not been able to reference them as part of my Grails Build Target: "build-applet ${svnRoot}/${svnBranch}/appletProject username password" "war --non-interactive". build-applet invokes a Gant script in the Grails project at scripts\BuildApplet.groovy.

  • After rich:extendedDataTable sortby, other actions are not getting executed

    - by kksachin
    I have several tabs and one of the tabs uses rich:extendedDataTable. If sortBy is clicked in the page where table is used and if I navigate to another page, it looks for the bean of the old page and throws an error saying that sortyBy of the column is undefined. E.g. If I use sortBy on userId in tab1 (where the column must have sortBy="#{data.userId}") and then I click on tab2, it looks for the data.userId and throws an error.

  • Best practice PHP Form Action

    - by Rob
    Hi there i've built a new script (from scratch not a CMS) and i've done alot of work on reducing memory usage and the time it takes for the page to be displayed (caching HTML etc) There's one thing that i'm not sure about though. Take a simple example of an article with a comments section. If the comment form posts to another page that then redirects back to the article page I won't have the problem of people clicking refresh and resending the information. However if I do it that way, I have to load up my script twice use twice as much memory and it takes twice as long whilst i'm still only displaying the page once. Here's an example from my load log. The first load of the article is from the cache, the second rebuilds the page after the comment is posted. Example 1 0 queries using 650856 bytes of memory in 0.018667 - domain.com/article/1/my_article.html 9 queries using 1325723 bytes of memory in 0.075825 - domain.com/article/1/my_article/newcomment.html 0 queries using 650856 bytes of memory in 0.029449 - domain.com/article/1/my_article.html Example 2 0 queries using 650856 bytes of memory in 0.023526 - domain.com/article/1/my_article.html 9 queries using 1659096 bytes of memory in 0.060032 - domain.com/article/1/my_article.html Obviously the time fluctuates so you can't really compare that. But as you can see with the first method I use more memory and it takes longer to load. BUT the first method avoides the refresh problem. Does anyone have any suggestions for the best approach or for alternative ways to avoid the extra load (admittadely minimal but i'd still like to avoid it) whilst also avoiding the refresh problem?

  • ASP.NET MVC Posted date field comes in as 1/1/0001

    - by engil
    Just started working with .NET and MVC(1). I'm having a problem wherein in my add action the entered date for some reason ends up as 1/1/0001 instead of what is entered thus causing a date overflow. In my model, this field ("Added") is is of type datetime and does not allow nulls. In my controller I have: public ActionResult Add() { Instance instance = new Instance() { Added = DateTime.Now, Active = true }; return View(instance); } [AcceptVerbs(HttpVerbs.Post)] public ActionResult Add(Instance instance) { if (ModelState.IsValid) { try { System.Diagnostics.Trace.Write("test"); instanceRepository.Add(instance); instanceRepository.Save(); return RedirectToAction("Details", new { id = instance.InstanceID }); } catch { ModelState.AddRuleViolations(instance.GetRuleViolations()); } } return View(instance); } And in my view I have: <div class="editor-label"> <%= Html.LabelFor(model => model.Added) %> </div> <div class="editor-field"> <%= Html.TextBoxFor(model => model.Added,String.Format("{0:g}",Model.Added))%> <%= Html.ValidationMessageFor(model => model.Added) %> When I first go to Instances/Add the default value is set correctly, however as soon as I submit the date turns into 1/1/0001 (from my understanding this indicates that it was either null or in an unrecognizable format) When I debug and palce a watch on Request.Form I see the date coming in encoded ie Request.Form {Added=4%2f9%2f2010+8%3a24%3a39+AM} - is this an issue? I know its probably not enough information to make a conlusive determination on why this is failing, but if someone could provide some good debugging tips on how to determine where the submitted date is getting munged I'd really appreciate it.

  • How to render an HTML attribute from a Razor view.

    - by ProfK
    I would like to use the same partial view for create, edit, and details views, to avoid duplicating the fieldset structure for an entity. Then, depending on which view renders the partial view, I would like to add a class of "read-only" to a div surrounding my fieldset and handle making the actual input fields read-only on the client, using css or jQuery, or whatever. How can I specify from my Razor view that I need this class added to the "item-details" div? <div class="item-details"> <fieldset> <legend>Product Details</legend> @Html.HiddenFor(model => model.DetailItem.ProductId) <div class="editor-label"> @Html.LabelFor(model => model.DetailItem.Name) </div> <div class="editor-field"> @Html.EditorFor(model => model.DetailItem.Name) @Html.ValidationMessageFor(model => model.DetailItem.Name) </div> <p> <input type="submit" value="Save" /> </p> </fieldset> </div>

  • Quick MVC2 checkbox question

    - by kevinmajor1
    In order to get my EF4 EntityCollection to bind with check box values, I have to manually create the check boxes in a loop like so: <p> <%: Html.Label("Platforms") %><br /> <% for(var i = 0; i < Model.AllPlatforms.Count; ++i) { %> <%: Model.AllPlatforms[i].Platform.Name %> <input type="checkbox" name="PlatformIDs" value="<%: Model.AllPlatforms[i].Platform.PlatformID %>" /><br /> <% } %> </p> It works, but it doesn't automatically populate the group of check boxes with existing values when I'm editing a model entity. Can I fudge it with something like? <p> <%: Html.Label("Platforms") %><br /> <% for(var i = 0; i < Model.AllPlatforms.Count; ++i) { %> <%: Model.AllPlatforms[i].Platform.Name %> <input type="checkbox" name="PlatformIDs" value="<%: Model.AllPlatforms[i].Platform.PlatformID %>" checked=<%: Model.GameData.Platforms.Any(p => PlatformID == i) ? "true" : "false" %> /><br /> <% } %> </p> I figure there has to be something along those lines which will work, and am just wondering if I'm on the right track. EDIT: I'm purposely staying away from MVC's check box HTML helper methods as they're too inflexible for my needs. My check boxes use integers as their values by design.

  • Interchange structured data between Haskell and C

    - by Eonil
    First, I'm a Haskell beginner. I'm planning integrating Haskell into C for realtime game. Haskell does logic, C does rendering. To do this, I have to pass huge complexly structured data (game state) from/to each other for each tick (at least 30 times per second). So the passing data should be lightweight. This state data may laid on sequential space on memory. Both of Haskell and C parts should access every area of the states freely. In best case, the cost of passing data can be copying a pointer to a memory. In worst case, copying whole data with conversion. I'm reading Haskell's FFI(http://www.haskell.org/haskellwiki/FFICookBook#Working_with_structs) The Haskell code look specifying memory layout explicitly. I have a few questions. Can Haskell specify memory layout explicitly? (to be matched exactly with C struct) Is this real memory layout? Or any kind of conversion required? (performance penalty) If Q#2 is true, Any performance penalty when the memory layout specified explicitly? What's the syntax #{alignment foo}? Where can I find the document about this? If I want to pass huge data with best performance, how should I do that? *PS Explicit memory layout feature which I said is just C#'s [StructLayout] attribute. Which is specifying in-memory position and size explicitly. http://www.developerfusion.com/article/84519/mastering-structs-in-c/ I'm not sure Haskell has matching linguistic construct matching with fields of C struct.

  • MVC4 - how to vaildate a drop down list?

    - by Grant Roy
    I have a .Net MVC4 model / view with a number of [Required] fields, one of which is selected via a drop down list, "Content_CreatedBy" [the first code block below]. Client side validation fires on all fields except the DDL [although server side validation does not allow no entry in DDL]. I have tried validating on the DDL text as well its numeric value but niether fire on the client side. Can anyone see what I am doing wrong? Thanks Model [Required] [Display(Name = "Author")] [ForeignKey("ContentContrib")] [Range(1, 99, ErrorMessage = "Author field is required.")] public virtual int Content_CreatedBy { get; set; } [Required] [Display(Name = "Date")] public virtual DateTime Content_CreatedDate { get; set; } [Required] [DataType(DataType.MultilineText)] [Display(Name = "Source / Notes ")] [StringLength(10, MinimumLength = 3)] public virtual string Content_Sources { get; set; } [Required] [Display(Name = "Keywords")] [StringLength(50, MinimumLength = 3)] public virtual string Content_KeyWords { get; set; } VIEW <div class="editor-label"> @Html.LabelFor(model => model.Content_CreatedBy, new { @class="whitelabel"}) </div> <div class="editor-field"> @Html.DropDownList("Content_CreatedBy", String.Empty) @Html.EditorFor(model => model.Content_CreatedBy) @Html.ValidationMessageFor(model => model.Content_CreatedBy) </div>

  • Are programming languages and methods inefficient? (assembler and C knowledge needed)

    - by b-gen-jack-o-neill
    Hi, for a long time, I am thinking and studying output of C language compiler in assembler form, as well as CPU architecture. I know this may be silly to you, but it seems to me that something is very ineffective. Please, don´t be angry if I am wrong, and there is some reason I do not see for all these principles. I will be very glad if you tell me why is it designed this way. I actually truly believe I am wrong, I know the genius minds of people which get PCs together knew a reason to do so. What exactly, do you ask? I´ll tell you right away, I use C as a example: 1: Stack local scope memory allocation: So, typical local memory allocation uses stack. Just copy esp to ebp and than allocate all the memory via ebp. OK, I would understand this if you explicitly need allocate RAM by default stack values, but if I do understand it correctly, modern OS use paging as a translation layer between application and physical RAM, when address you desire is further translated before reaching actual RAM byte. So why don´t just say 0x00000000 is int a,0x00000004 is int b and so? And access them just by mov 0x00000000,#10? Because you wont actually access memory blocks 0x00000000 and 0x00000004 but those your OS set the paging tables to. Actually, since memory allocation by ebp and esp use indirect addressing, "my" way would be even faster. 2: Variable allocation duplicity: When you run application, Loader load its code into RAM. When you create variable, or string, compiler generates code that pushes these values on the top o stack when created in main. So there is actual instruction for do so, and that actual number in memory. So, there are 2 entries of the same value in RAM. One in form of instruction, second in form of actual bytes in the RAM. But why? Why not to just when declaring variable count at which memory block it would be, than when used, just insert this memory location?

  • Master Detail same View binding controls

  • are there requirements for Struts setters beyond variable name matching?

    - by slk
    I have a model-driven Struts Web action: public class ModelDrivenAction<T extends Object> implements ModelDriven<T>, Preparable { protected Long id; protected T model; @Override public void prepare() {} public void setId(Long id) { this.id = id; } @Override public T getModel() { return model; } public void setModel(T model) { this.model = model; } } I have another action which is not currently model-driven: public class OtherAction implements Preparable { private ModelObj modelObj; private Long modelId; @Override public void prepare() { modelObj = repoService.retrieveModelById(modelId); } public void setModelId(Long modelId) { this.modelId = modelId; } } I wish to make it so, and would like to avoid having to track down all the instances in JavaScript where the action is passed a "modelId" parameter instead of "id" if at all possible. I thought this might work, so either modelId or id could be passed in: public class OtherAction extends ModelDrivenAction<ModelObj> { @Override public void prepare() { model = repoService.retrieveModelById(id); } public void setModelId(Long modelId) { this.id = modelId; } } However, server/path/to/other!method?modelId=123 is failing to set id. I thought so long as a setter matched a parameter name the Struts interceptor would call it on action invocation. Am I missing something here?

  • calling same function on different buttons not loaded yet

    - by Jordan Faust
    I can not get this to work for every button and I cannot find anything explaining why. I guessing it is something small that I am missing $(document).ready(function() { // delete the selected row from the database $(document).on('click', '#business-area-delete-button', { model: "BusinessArea" }, deleteRow); $(document).on('click', '#business-type-delete-button', { model: "BusinessType" }, deleteRow); $(document).on('click', '#client-delete-button', { model: "Client" }, deleteRow); $(document).on('click', '#client-type-delete-button', { model: "ClientType" }, deleteRow); $(document).on('click', '#communication-channel-type', { model: "CommunicationChannelType" }, deleteRow); $(document).on('click', '#parameter-type-delete-button', { model: "ParameterType" }, deleteRow); $(document).on('click', '#validation-method-delete-button', { model: "ValidationMethod" }, deleteRow); } the event function deleteRow(event){ $.ajax( { type:'POST', data: { id: $(".delete-row").attr("id") }, url:"/mysite/admin/delete" + event.data.model, success:function(data,textStatus){ $('#main-content').html(data); }, error:function(XMLHttpRequest,textStatus,errorThrown){ jQuery('#alerts').html(XMLHttpRequest.responseText); }, complete:function(XMLHttpRequest,textStatus){ placeAlerts() } } ); return false }; This works only for a the button with id validation-method-delete-button. I use document and not the button its self because the button is contained in a template that is loaded later via ajax. I have this working for a similar function that is selecting a row in a table however I am not attempting to pass data in that scenario.

  • Design patterns for Caching Images in a MVC?

    - by Onema
    Hi, I'm designing an image cache system that will be used in an MVC CMS. The main purpose of the image cacher is to modify images: scale, crop, etc and cache them in the client site. I have created an image cache Model and Mapper that interact with the Database, to keep track of the images and know what kind of actions have been applied to them (scale, crop, etc). In addition to the Model and Mapper I have created a ImageCacher Class that is used by the API to manage the Model and image creation based on arguments passed by the client site, this class creates the images and generates the links to the images for the View. A coworker argued that I need to include the functionality of this last Class inside the Model, as the bulk of the logic should go in the model. I respectfully disagree with him since I feel the model's responsibility is to deal with the information about the images cached at the database level, and the responsibility of the ImageCacher Class is to create the url/image that we will be caching (keeping the single responsibility principle). In addition to this I believe that a model should not have Presentation-related features, like creating or showing images. Does anyone have any insight on this? is there a particular design pattern that would make this division of tasks clear and and the image cacher reusable? Should I add all the logic in the Model? Thank you.

  • mvc design in a card game

    - by Hong
    I'm trying to make a card game. some classes I have are: CardModel, CardView; DeckModel, DeckView. The deck model has a list of card model, According to MVC, if I want to send a card to a deck, I can add the card model to the deck model, and the card view will be added to the deck view by a event handler. So I have a addCard(CardModel m) in the DeckModel class, but if I want to send a event to add the card view of that model to the deck view, I only know let the model has a reference to view. So the question is: If the card model and deck model have to have a reference to their view classes to do it? If not, how to do it better? Update, the code: public class DeckModel { private ArrayList<CardModel> cards; private ArrayList<EventHandler> actionEventHandlerList; public void addCard(CardModel card){ cards.add(card); //processEvent(event x); //must I pass a event that contain card view here? } CardModel getCards(int index){ return cards.get(index); } public synchronized void addEventHandler(EventHandler l){ if(actionEventHandlerList == null) actionEventHandlerList = new ArrayList<EventHandler>(); if(!actionEventHandlerList.contains(l)) actionEventHandlerList.add(l); } public synchronized void removeEventHandler(EventHandler l){ if(actionEventHandlerList!= null && actionEventHandlerList.contains(l)) actionEventHandlerList.remove(l); } private void processEvent(Event e){ ArrayList list; synchronized(this){ if(actionEventHandlerList!= null) list = (ArrayList)actionEventHandlerList.clone(); else return; } for(int i=0; i<actionEventHandlerList.size(); ++i){ actionEventHandlerList.get(i).handle(e); } } }

  • Are programming languages and methods ineffective? (assembler and C knowledge needed)

    - by b-gen-jack-o-neill
    Hi, for a long time, I am thinking and studying output of C language compiler in asemlber form, as well as CPU architecture. I know this may be silly to you, but it seems to me that something is very ineffective. Please, don´t be angry if I am wrong, and there is some reason I do not see for all these principles. I will be very glad if you tell me why is it designed this way. I actually trully believe I am wrong, I know the genius minds of people which get PCs together knew a reason to do so. What exactly, do you ask? I´ll tell you right away, I use C as a example: 1, Stack local scope memory allocation: So, typical local memory allocation uses stack. Just copy esp to ebp and than allocate all the memory via ebp. OK, I would understand this if you explicitly need allocate RAM by default stack values, but if I do understand it correctly, modern OS use paging as a translation layer between application and physical RAM, when adress you desire is further translated before reaching actuall RAM byte. So why don´t just say 0x00000000 is int a,0x00000004 is int b and so? And access them just by mov 0x00000000,#10? Becouse you wont actually access memory blocks 0x00000000 and 0x00000004 but those your OS set the paging tables to. Actually, since memory allocation by ebp and esp use indirect adressing, "my" way would be even faster. 2, Variable allocation duplicitly: When you run aaplication, Loader load its code into RAM. When you create variable, or string, compiler generates code that pushes these values on the top o stack when created in main. So there is actuall instruction for do so, and that actuall number in memory. So, there are 2 entries of the same value in RAM. One in fomr of instruction, second in form of actuall bytes in the RAM. But why? Why not to just when declaring variable count at which memory block it would be, than when used, just insert this memory location?

  • how can I code a recursive query in an Entity Framework model?

    - by Greg
    Hi, I have a model which includes NODES, and RELATIONSHIPS (that tie the nodes together, via a parent_node, child_node arrangement). Q1 - Is there any way in EF / Linq-to-entities to perform a query on nodes (e.g. context.Nodes..) to find say "all parents" or "or children" in the graph? Q2 - If there's not in Linq-to-entities, is there any other way to do this other than writing a method that manually goes through and doing it? Q3 - If manual is the only way to do it, should I be concerned about the number of database hits that will be going out to the database as the method keeps recursing through the data? Or more specifically, is there any EF caching type feature that might assist here in ensuring the method is performance from a "number of database hits" point of view? thanks thanks

  • iPhone: How to store a location (CLLocationCoordinate2D) inside a class w/o leaking memory?

    - by Henry
    I am creating a library which contains an API for setting the current location based off some value collected by the GPS. I want to store this location in my class and later, change the behavior of my library if it is set. What I had in mind was: @interface myLib { @property (nonatomic, retain) CLLocationCoordinate2D *location; } @implementation myLib { @synthesize location = _location; - (void)setLocation:(CLLocationCoordinate2D *)loc { location = loc; } - (void)someFunc { if (location != nil) ... } } However, retain isn't a valid property for a CLLocationCoordinate2D object. So, what is the proper way to save CLLocationCoordinate2D for later use w/o wasting memory? Thanks in advance!

  • MSB3422 Failed to retrieve VC project information through the VC project engine object model. MSB342

    - by Scott Langham
    I'm getting the following errors from MSBuild while trying to build a solution: C:\dev\MySln.sln : warning MSB3422: Failed to retrieve VC project information through the VC project engine object model. Unable to determine default tool for the specified file configuration. C:\dev\MySln.sln : warning MSB3425: Could not resolve VC project reference "C:\dev\MyProj.vcproj". Have you got any ideas on what's causing this? I've seen other postings about similar, but different errors such as when the MSB3422 error has a different message and shows "Illegal characters in path.", but I haven't seen any useful information about how to solve the error I'm getting where it says "Unable to determine default tool for the specified file configuration.". Thanks. I found this, but it doesn't really help: http://social.msdn.microsoft.com/Forums/en-US/msbuild/thread/b470f111-9321-4b43-8bd1-7fcf67c2d402

  • Can the Windows Media Player COM control play AVI files from memory (instead of from a file)?

    - by MusiGenesis
    I have a C# app, and I'm looking at using the Windows Media Player COM control to play animation and audio. So far, the only way I see of programatically controlling what the control is playing is to set its URL property to point to some file (I assume there's some way to pass in a playlist). Is there any way the WMP can render an AVI that is entirely in-memory, like a MemoryStream or something? If so, can WMP skip from one AVI to the next seamlessly (i.e. no glitch in either the audio or the video as it transitions from one to the next)? If WMP only plays files, is there some way to cue up a list of the files in advance of play start? If so, can WMP be made to skip from one file to the next without a brief interruption? Any knowledge or links to knowledge would be much appreciated.

  • Extending User object in Django: User model inheritance or use UserProfile?

    - by Chris
    To extend the User object with custom fields, the Django docs recommend using UserProfiles. However, according to this answer to a question about this from a year or so back: extending django.contrib.auth.models.User also works better now -- ever since the refactoring of Django's inheritance code in the models API. And articles such as this lay out how to extend the User model with custom fields, together with the advantages (retrieving properties directly from the user object, rather than through the .get_profile()). So I was wondering whether there is any consensus on this issue, or reasons to use one or the other. Or even what the Django team currently think?
