• Garbage collecting at ColdFusion CFC

  - by Sergii

  Hello. I have a CFC as singletone object in Application scope. One of the methods is used for massive data processing and periodically causes the "Java heap space" errors. EDIT All variables inside the method are VAR-scoped, so they should not be kept in the object scope when invokation ended. It can be a bit dumb question for Java people, but I'd like to know how Java garbage collector cleans up the CFC methods memory: only when whole request ends, or maybe right after each method/function invokation? Second option is interesting because it can allow me to split my large method into the few, as one of the possible optimizations.

• Design - Where should objects be registered when using Windsor

  - by Fredrik Jansson

  I will have the following components in my application DataAccess DataAccess.Test Business Business.Test Application I was hoping to use Castle Windsor as IoC to glue the layers together but I am bit uncertain about the design of the gluing. My question is who should be responsible for registering the objects into Windsor? I have a couple of ideas; Each layer can register its own objects. To test the BL, the test bench could register mock classes for the DAL. Each layer can register the object of its dependencies, e.g. the business layer registers the components of the data access layer. To test the BL, the test bench would have to unload the "real" DAL object and register the mock objects. The application (or test app) registers all objects of the dependencies. Can someone help me with some ideas and pros/cons with the different paths? Links to example projects utilizing Castle Windsor in this way would be very helpful.

• Documentation generator for Google Closure Javascript

  - by Julius Eckert

  I want to generate a HTML-Documentation for my Javascript code. The comments in my code are written in a format, the Google Closure Compiler can use to optimize my code. Example: /** * Class for handling timing events. * * @param {number=} opt_interval Number of ms between ticks (Default: 1ms). * @param {Object=} opt_timerObject An object that has setTimeout, setInterval, * clearTimeout and clearInterval (eg Window). * @constructor * @extends {goog.events.EventTarget} */ goog.Timer = function(opt_interval, opt_timerObject) { ... } I am looking for something like http://yardoc.org for Javascript. What tools can you recommend? Are there any specific tools for Google Closure code?

• Get multiple records with one query

  - by Lewy

  User table: name lastname Bob Presley Jamie Cox Lucy Bush Find users q = Query.new("Bob Presley, Cox, Lucy") q.find_users => {0=>{:name=>"Bob", :lastname=>"Presley"}, 1=>{:lastname=>"Cox"}, 2=>{:name=>"Lucy"}} Question: I've got hash with few names and lastnames. I need to build Activerecord query to fetch all users from that hash. I can do object = [] hash = q.find_users hash.each do |data| #check if data[:lastname] and data[:name] exist # object << User.where(:name => ..., :lastname => ...) end But I think it is higly inefficient. How should I do this ?

• Marshal a list of objects from VB6 to C#

  - by Andrew

  I have a development which requires the passing of objects between a VB6 application and a C# class library. The objects are defined in the C# class library and are used as parameters for methods exposed by other classes in the same library. The objects all contain simple string/numeric properties and so marshaling has been relatively painless. We now have a requirement to pass an object which contains a list of other objects. If I was coding this in VB6 I might have a class containing a collection as a member variable. In C# I might have a class with a List member variable. Is it possible to construct a C# class in such a way that the VB6 application could populate this inner list and marshal it successfully? I don't have a lot of experience here but I would guess Id have to use an array of Object types.

• Convert a generic list to an array

  I have searched for this, but unfortunately, I don't get the correct answer. class Helper { public static <T> T[] toArray(List<T> list) { T[] array = (T[]) new Object[list.size()]; for (int i = 0; i < list.size(); i++) { array[i] = list.get(i); } return array; } } Test it: public static void main(String[] args) { List<String> list = new ArrayList<String>(); list.add("abc"); String[] array = toArray(list); System.out.println(array); } But there is an error thrown: Exception in thread "main" java.lang.ClassCastException: [Ljava.lang.Object; cannot be cast to [Ljava.lang.String; at test.Helper.main(Helper.java:30) How to solve this?

• GraphicsDevice is null in my XNA Windows Game project

  - by indyK1ng

  Hello All, I have just started trying to make a simple game with XNA 3.1 to help myself learn C# and XNA. I have run into a bit of an interesting problem, however. In all of the tutorials, one is supposed to pass GraphicsDevice when instantiating a new spriteBatch object like this: spriteBatch = new SpriteBatch(GraphicsDevice); One might even do this: GraphicsDevice objGraphics = new graphics.GraphicsDevice; spriteBatch = new SpriteBatch(objGraphics); where graphics is the GraphicsDeviceManager. However, no matter which version I try, I always get an ArgumentNullException when I try to pass the GraphicsDevice object to spriteBatch's constructor. Almost every tutorial I have found gives the first one and only one mentioned the second option. Has anyone else run into a similar error or know what could be causing this? I am working in Windows 7 x64 with Visual Studio 2008.

• Where is the method call in the EXE file?

  - by Victor Hurdugaci

  Introduction After watching this video from LIDNUG, about .NET code protection http://secureteam.net/lidnug_recording/Untitled.swf (especially from 46:30 to 57:30), I would to locate the call to a MessageBox.Show in an EXE I created. The only logic in my "TrialApp.exe" is: public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void Form1_Load(object sender, EventArgs e) { MessageBox.Show("This is trial app"); } } Compiled on the Release configuration: http://rapidshare.com/files/392503054/TrialApp.exe.html What I do to locate the call Run the application in WinDBG and break after the message box appears. Get the CLR stack with !clrstack: 0040e840 5e21350b [InlinedCallFrame: 0040e840] System.Windows.Forms.SafeNativeMethods.MessageBox(System.Runtime.InteropServices.HandleRef, System.String, System.String, Int32) 0040e894 5e21350b System.Windows.Forms.MessageBox.ShowCore(System.Windows.Forms.IWin32Window, System.String, System.String, System.Windows.Forms.MessageBoxButtons, System.Windows.Forms.MessageBoxIcon, System.Windows.Forms.MessageBoxDefaultButton, System.Windows.Forms.MessageBoxOptions, Boolean) 0040e898 002701f0 [InlinedCallFrame: 0040e898] 0040e934 002701f0 TrialApp.Form1.Form1_Load(System.Object, System.EventArgs) Get the MethodDesc structure (using the address of Form1_Load) !ip2md 002701f0 MethodDesc: 001762f8 Method Name: TrialApp.Form1.Form1_Load(System.Object, System.EventArgs) Class: 00171678 MethodTable: 00176354 mdToken: 06000005 Module: 00172e9c IsJitted: yes CodeAddr: 002701d0 Transparency: Critical Source file: D:\temp\TrialApp\TrialApp\Form1.cs @ 22 Dump the IL of this method (by MethodDesc) !dumpil 001762f8 IL_0000: ldstr "This is trial app" IL_0005: call System.Windows.Forms.MessageBox::Show IL_000a: pop IL_000b: ret So, as the video mentioned, the call to to Show is 5 bytes from the beginning of the method implementation. Now I open CFFExplorer (just like in the video) and get the RVA of the Form1_Load method: 00002083. After this, I go to Address Converter (again in CFF Explorer) and navigate to offset 00002083. There we have: 32 72 01 00 00 70 28 16 00 00 0A 26 2A 7A 03 2C 13 02 7B 02 00 00 04 2C 0B 02 7B 02 00 00 04 6F 17 00 00 0A 02 03 28 18 00 00 0A 2A 00 03 30 04 00 67 00 00 00 00 00 00 00 02 28 19 00 00 0A 02 In the video is mentioned that the first 12 bytes are for the method header so I skip them 2A 7A 03 2C 13 02 7B 02 00 00 04 2C 0B 02 7B 02 00 00 04 6F 17 00 00 0A 02 03 28 18 00 00 0A 2A 00 03 30 04 00 67 00 00 00 00 00 00 00 02 28 19 00 00 0A 02 5 bytes from the beginning of the implementation should be the opcode for method call (28). Unfortunately, is not there. 02 7B 02 00 00 04 2C 0B 02 7B 02 00 00 04 6F 17 00 00 0A 02 03 28 18 00 00 0A 2A 00 03 30 04 00 67 00 00 00 00 00 00 00 02 28 19 00 00 0A 02 Questions: What am I doing wrong? Why there is no method call at that position in the file? Or maybe the video is missing some information... Why the guy in that video replaces the call with 9 zeros?

• Anything wrong with this code?

  - by ct2k7

  I am using this to determine which view to go to next, from the result as input from UITableView. The following code isn't working, but I think it should be! Do you see anything wrong with it? NSString *option = [menuArray objectAtIndex:indexPath.row]; if (option == @"New Transaction"){ NTItems *nTItemsController = [[NTItems alloc] initWithNibName:@"NTItems" bundle:nil]; // Pass the selected object to the new view controller. [self.navigationController pushViewController:nTItemsController animated:YES]; [NTItems release];} else if (option == @"Previous Transactions"){} else if (option == @"Reprint a reciept"){} else if (option == @"Settings"){} else if (option == @"Logout"){ LoginViewController *nTItemsController = [[LoginViewController alloc] initWithNibName:@"LoginViewController" bundle:nil]; // Pass the selected object to the new view controller.

• jQuery style Constructors in PHP

  - by McB

  Is there a way to instantiate a new PHP object in a similar manner to those in jQuery? I'm talking about assigning a variable number of arguments when creating the object. For example, I know I could do something like: ... //in my Class __contruct($name, $height, $eye_colour, $car, $password) { ... } $p1 = new person("bob", "5'9", "Blue", "toyota", "password"); But I'd like to set only some of them maybe. So something like: $p1 = new person({ name: "bob", eyes: "blue"}); Which is more along the lines of how it is done in jQuery and other frameworks. Is this built in to PHP? Is there a way to do it? Or a reason I should avoid it?

• How would I UPDATE these table entries with SQL and PHP?

  - by CT

  I am working on an Asset Database problem. I enter assets into a database. Every object is an asset and has variables within the asset table. An object is also a type of asset. In this example the type is server. Here is the Query to retrieve all necessary data: SELECT asset.id ,asset.company ,asset.location ,asset.purchaseDate ,asset.purchaseOrder ,asset.value ,asset.type ,asset.notes ,server.manufacturer ,server.model ,server.serialNumber ,server.esc ,server.warranty ,server.user ,server.prevUser ,server.cpu ,server.memory ,server.hardDrive FROM asset LEFT JOIN server ON server.id = asset.id WHERE asset.id = '$id' I then assign all results into single php variables. How would I write a query/script to update an asset?

• CreateChildControls AFTER Postback

  - by Francois

  I'm creating my own CompositeControl: a collection of MyLineWebControl and a "add" button. When the user press the "add" button, a new MyLineWebControl is added. In CreateChildControls(), I run through my model (some object MyGridOfLines which has a collection of MyLine) and add one MyLineWebControl for each MyLine. In addButton.Click, I add a new MyLine to my object MyGridOfLines. But, since the Click event method is called after CreateChildControls(), the new MyLineWebControl will be only displayed on the next postback. What can I do to "redraw" immediately my control, without loosing values that I've entered in each input?

• ajax response byte size

  - by Alex Pacurar

  Im using jQuery's getJSONP and I want to log the duration of the call and the size of the response to be able to have some statistics about the usage of my application. This is a cross domain ajax call, so I need to use JSONP, but as the JSONP call is not done with an XMLHttpRequest object, the complete callback from jquery's ajax doesnt pass the response content. So my question is how to get the response size (content lenght) from a JSONP call. $.ajaxSetup( { complete:function(x,e) { log(x.responseText.length, x.responseText); } } here x is a XMLHttpRequest object for a JSON call , but for JSONP call is undefined.

• set current user in asp.net mvc

  - by Tomh

  Hey guys, I'm not sure if this is the best way to do it, but I want to keep a user object alive during all requests of the current user. From reading several resources I learned that you should create your own IPrinciple which holds this. But I don't want to trigger the database every authentication request. Any recommendations on how to handle this? Is caching the db request a good idea? protected void Application_AuthenticateRequest(Object sender, EventArgs e) { HttpCookie authCookie = Request.Cookies[FormsAuthentication.FormsCookieName]; if (authCookie != null) { FormsAuthenticationTicket authTicket = FormsAuthentication.Decrypt(authCookie.Value); User user; using (HgDataContext hg = new HgDataContext()) { if (Session["user"] != null) { user = (from u in hg.Users where u.EmailAddress == authTicket.Name select u).Single(); } else { user = Session["user"] as User; } } var principal = new HgPrincipal(user); Context.User = principal; } }

• Android (Milestone/Droid): View.OnKeyListener not working correctly?

  - by Ice09

  I am using a simple EditText and register an View.OnKeyListener. Some GUI changes should happen (fading in/out of views) when certain conditions for the EditView text apply. In the emulator, this works as expected. On the Motorola Droid/Milestone, the listener does not work, only after pressing DEL, the listener is called the first time and always afterwards when activating the number input, the listener works correctly Note: I deactivated the suggestions with TYPE_TEXT_FLAG_NO_SUGGESTIONS and used the IME action IME_ACTION_GO to have a workaround for this (otherwise the user could not "start" a request).

• How to display unique success messages on jquery form validation

  Hi guys, hope you can help me on this one, I'm currently using this: jQuery plugin:validation (Homepage) I've been reading related questions here, but this one is the closest get. http://stackoverflow.com/questions/1863448/jquery-validation-on-success from the plugin's documentation http://docs.jquery.com/Plugins/Validation/validate#toption success String, Callback If specified, the error label is displayed to show a valid element. If a String is given, its added as a class to the label. If a Function is given, its called with the label (as a jQuery object) as its only argument. That can be used to add a text like "ok!". Currently I'm only object given to me is the label, and I can only add text to it. Now what I want is to have unique success message. For example: username field will have a success message: 'username okay!' email = 'email seems right' something along those lines, instead of displaying just one generic success message on all the fields.

• Render only the segment/area of a circle that intersects the main circle

  - by Greenhouse Gases

  I absolutely love maths (or 'math' as most of you would say!) but I haven't done it to a level where I know the answer to this problem. I have a main circle which could have a centre point at any x and y on a display. Other circles will move around the display at will but at any given call to a render method I want to render not only those circles that intersect the main circle, but also only render the segment of that circle that is visible inside the main circle. An analogy would be a shadow cast on a real life object, and I only want to draw the part of that object that is 'illuminated'. I want to do this preferably in Java, but if you have a raw formula that would be appreciated. I wonder how one might draw the shape and fill it in Java, I'm sure there must be some variation on a polyline with arcs or something? Many thanks

• Will this safely delete my record?

  - by Sergio Tapia

  I hate these three tables that. Two tables have a many to many relationship and as such it generates a third table. I'm using Linq-to-SQL and in the .dbml file I've dragged all the folder there to the graphic surface. Here is the method I'm using to delete an Area safely. Remember that documents are associated to an Area, so I can't just delete it and leave documents hanging. ScansDataContext db = new ScansDataContext(); /// <summary> /// Deletes an Area object from the database along with all associations in the database. /// </summary> /// <param name="area">Area object to save</param> public void Delete(Area area) { db.DocumentAreaRelations.DeleteAllOnSubmit(area.DocumentAreaRelations); db.Areas.DeleteOnSubmit(area); db.SubmitChanges(System.Data.Linq.ConflictMode.FailOnFirstConflict); }

• jquery live event gets executed twice

  I am loading content into a page with ajax that will have live click events attached to them. It seems like the first time I load this content everything works as expected. If I load this again, the events fire twice (when put breakpoints in the code). What am I doing wrong? Is there a way I can clear the dom of these elements before they get loaded again?
