• How are $LOAD_PATH and $: different?

  - by Benjamin Oakes

  I needed to know what was in my Ruby load path, so I did this: $ ruby -e "puts $LOAD_PATH" It didn't print anything out, which I didn't expect. So I tried this: $ ruby -e "puts $:" /usr/local/lib/site_ruby/1.8 /usr/local/lib/site_ruby/1.8/i486-linux /usr/local/lib/site_ruby/1.8/i386-linux /usr/local/lib/site_ruby /usr/lib/ruby/vendor_ruby/1.8 /usr/lib/ruby/vendor_ruby/1.8/i486-linux /usr/lib/ruby/vendor_ruby /usr/lib/ruby/1.8 /usr/lib/ruby/1.8/i486-linux /usr/lib/ruby/1.8/i386-linux . Why does the second one give me the expected output and the first one doesn't? Shouldn't they be the same? I just tried it in irb, and I got the results I expected. This is my Ruby version, in case it makes a difference: $ ruby --version ruby 1.8.7 (2008-08-11 patchlevel 72) [i486-linux]

• JSF/HTML - Add a java applet to web page programmaticly.

  - by Ben

  Hi, Theres a web page i'm making which content is very dynamic and so I'm building it from inside the backing bean. I would like to add a java applet to the web page but I could not find the Java Object to correspond to the <applet> tag. So My questions are - What is the JAVA Object for an applet? How did you find it? (For similar future searches) Thanks! P.S - Just to be clear. An example: <h:PanelGroup> would be HtmlPanelGroup as a java object.

• FETCH INTO doesn't raise an exception if the set is empty, does it?

  - by Cade Roux

  Here is some actual code I'm trying to debug: BEGIN OPEN bservice (coservice.prod_id); FETCH bservice INTO v_billing_alias_id, v_billing_service_uom_id, v_summary_remarks; CLOSE bservice; v_service_found := 1; -- An empty fetch is expected for some services. EXCEPTION WHEN OTHERS THEN v_service_found := 0; END; When the parametrized cursor bservice(prod_id) is empty, it fetches NULL into the three variables and does not throw an exception. So whoever wrote this code expecting it to throw an exception was wrong, right? The comment seems to imply that and empty fetch is expected and then it sets a flag for later handling, but I think this code cannot possibly have been tested with empty sets either. Obviously, it should use bservice%NOTFOUND or bservice%FOUND or similar.

• Make SharePoint 2007 List View read-only

  - by FireSnake

  I need to deploy a new List View for the standard List View Web Part in MOSS 2007 via the object model (the list already exists, a new view should be added). I need and want to make this list view read-only. This is because saving changes to the view would corrupt modifications made to Header/Footer. How can I do that via the object model? I looked at the content db, the read-only flag (0x20) is stored with the view and could technically be updated using calls to proc_GetAllWebPartsOnPage and proc_UpdateView[Properties]. NOTE: The database interface and all mentioned stored procs are all documented by Microsoft. Is there ANY way to do that via the object model, because I would strongly prefer that?

• Information Modeling

  - by Betamoo

  The sensor module in my project consists of a rotating camera, that collects noisy information about moving objects in the surrounding environment. The information consists of distance, angle and relative change of the moving objects.. The limiting view range of the camera makes it essential to rotate the camera periodically to update environment information... I was looking for algorithms / ways to model these information, in order to be able to guess / predict / learn motion properties of these object.. My current proposed idea is to store last n snapshots of each object in a queue. I take weighted average of positions and velocities of moving object, but I think it is a poor method... Can you state some titles that suit this case? Thanks

• Why "constructor-way" of declaring variable in "for-loop" allowed but in "if-statement" not allowed?

  - by PiotrNycz

  Consider this simple example: /*1*/ int main() { /*2*/ for (int i(7); i;){break;} /*3*/ if (int i(7)) {} /*4*/ } Why line-2 compiles just fine, whilst line-3 gives the error? This is little strange to me why if-statement is in this aspect treated worse than for-loop? If this is compiler specific - I tested with gcc-4.5.1: prog.cpp: In function 'int main()': prog.cpp:3:7: error: expected primary-expression before 'int' prog.cpp:3:7: error: expected ')' before 'int' I was inspired by this question [UPDATE] I know this compiles just fine: /*1*/ int main() { /*2*/ for (int i = 7; i;){break;} /*3*/ if (int i = 7) {} /*4*/ }

• What is dbReferenceProperty?

  - by user246114

  Hi, In the python app engine docs, I see something called dbReferenceProperty. I can't understand what it is, or how it's used. I'm using the java interface to app engine, so I'm not sure if there's an equivalent. I'm interested in it because it sounds like some sort of pseudo-join, where we can point a property of a class to some other object's value - something like if we had: class User { private String mPhotoUrl; private String mPhone; private String mState; private String mCountry; .. etc .. } class UserLite { @ReferenceProperty User.mPhotoUrl; private String mPhotoUrl; } then if we had to update a User object's mPhotoUrl value, the change would somehow propagate out to all UserLite instances referencing it, rather than having to update every UserLite object instance manually, Thanks

• Sum of distinc rows after a 1-many table join

  - by Lock

  I have 2 tables that I am joining. Table 1 has 1-many relationship with table 2. That is, table 2 can return multiple rows for a single row of table 1. Because of this, the records of table 1 is duplicated for as many rows as are on table 2.. which is expected. Now, I have a sum on one of the columns from table 1, but because of the multiple rows that get returned on the join, the sum is obviously multiplying. Is there a way to get this number back to its original number? I tried dividing by the count of rows from table 2 but this didnt quite give me the expected result. Are there any analytical functions that could do this? I almost want something like "if this row has not yet been counted in the sum, add it to the sum"

• Need some help in understanding SSL concepts

  - by user1115256

  I am new to SSL programming and finding some difficulties in understanding SSL concepts. I tried to get it through openssl site,but it is not much informative. Here is my doubts. What is difference between SSL Buffer and BIO buffer..? I mean layerwise detail will be very helpful. Can I use SSL_Write and SSL_Read without setting any BIO object to SSL object..? What exactly BIO_flush will do... I mean is it going to flush all the data to network buffer from BIO buffer.. ? If it is possible to do write and read data from SSL directly without using any BIO object then is it possible to flush the data from SSL buffer to network buffer by any means.. ? It would be very helpful if any body explain these things or giving any links where I can find answers to my questions.

• Modern way to validate POST-data in MVC 2

  - by zerkms

  There are a lot of articles devoted to working with data in MVC, and nothing about MVC 2. So my question is: what is the proper way to handle POST-query and validate it. Assume we have 2 actions. Both of them operates over the same entity, but each action has it's own separated set of object properties that should be bound in automatic manner. For example: Action "A" should bind only "Name" property of object, taken from POST-request Action "B" should bind only "Date" property of object, taken from POST-request As far as I understand - we cannot use Bind attribute in this case. So - what are the best practices in MVC2 to handle POST-data and probably validate it.

• Generically creating objects in C#

  - by DrLazer

  What I am trying to do is load in objects from an XML save file. The problem is those objects are configurable by the user at runtime, meaning i had to use reflection to get the names and attributes of those objects stored in an XML file. I am in the middle of a recursive loop through the XML and up to the part where I need to create an object then thought ..... ah - no idea how to do that :( I have an array stuffed with empty objects (m_MenuDataTypes), one of each possible type. My recursive loading function looks like this private void LoadMenuData(XmlNode menuDataNode) { foreach (object menuDataObject in m_MenuDataTypes) { Type menuDataObjectType = menuDataObject.GetType(); if (menuDataObjectType.Name == menuDataNode.Name) { //create object } } } I need to put some code where my comment is but I can't have a big switch statement or anything. The objects in my array can change depending on how the user has configured the app.

• Use CSS (and maybe JavaScript) to make an element be square (or maintain a specific aspect ratio)

  - by David Pfeffer

  I have a div that I want to have the following characteristics: Width = 50% of its parent element Height equal to whatever it needs to be in order to maintain a certain aspect ratio. I need to use percentages because the object will resize left-right when the browser is resized. I want the object to be resized top-bottom to ensure the object maintains the same aspect ratio. I don't think there's any way to use pure CSS to do this, but does anyone know of a way? Alternatively, is there an easy JavaScript way to do this? (JQuery is fine.)

• How to avoid double construction of proxy with DynamicProxy::CreateClassProxyWithTarget?

  - by Belvasis

  I am decorating an existing object using the CreateClassProxyWithTarget method. However, the constructor and therefore, initialization code, is being called twice. I already have a "constructed" instance (the target). I understand why this happens, but is there a way to avoid it, other than using an empty constructor? Edit: Here is some code: First the proxy creation: public static T Create<T>(T i_pEntity) where T : class { object pResult = m_pGenerator.CreateClassProxyWithTarget(typeof(T), new[] { typeof(IEditableObject), typeof(INotifyPropertyChanged) , typeof(IMarkerInterface), typeof(IDataErrorInfo) }, i_pEntity, ProxyGenerationOptions.Default, new BindingEntityInterceptor<T>(i_pEntity)); return (T)pResult; } I use this for example with an object of the following class: public class KatalogBase : AuditableBaseEntity { public KatalogBase() { Values = new HashedSet<Values>(); Attributes = new HashedSet<Attributes>(); } ... } If i now call BindingFactory.Create(someKatalogBaseObject); the Values and Attributes properties are beeing initialized again.

• howto launch my application like MS-Office applications do using automation.

  - by Alan

  I am writing a c# application which references a separate dll which contains all the automation features i am trying to implement such as Application Object Model, doing all this by using delegates and events. What i want to be able todo is to reference my dll containing the application object model in a different process and for it to automatically launch my application, like MS-Word does when you call its application. Example: Microsoft.Office.Interop.Word.Application wordApp = new Microsoft.Office.Interop.Word.Application(); Word object model loads in the WinWord.exe running its own process how can i achieve this as well. Thanks in advance

• How can I use multithreading in a Windows Forms application to update a progress bar?

  - by Steve Syfuhs

  There are two objects. The Windows Form with a button and a progress bar, and another object that handles an algorithm. In the algorithm object there is an event, and a property. The event is ProgressChanged, and the property is Progress (which is an int). In the calling window, the button starts off a set of steps in the algorithm object. As each step (or substeps) occurs, the ProgressChanged event fires, and in the window there is an event handler that essentially increments the progress bar relative to the Progress property. The problem I am running into is that because the algorithm has a possibility (and high liklihood) of running a relatively long time, I need to move it into it's own background thread and push the event back up to the window. My issue is that I'm not completely sure what I'm doing when it comes to multi-threading. I've looked at Control.Invoke and I'm a little lost. Can someone point me in the right direction?

• Instantiating class by string using PHP 5.3 namespaces

  - by Kevin

  I can't get around an issue instantiating a new class by using a string variable and PHP 5.3. namespaces. For example, this works; $class = 'Reflection'; $object = new $class(); However, this does not; $class = '\Application\Log\MyClass'; $object = new $class(); A fatal error gets thrown stating the class cannot be found. However it obviously can be instantiated if using the FQN i.e.; $object = new \Application\Log\MyClass; I've found this to be aparrent on PHP 5.3.2-1 but not not in later versions. Is there a work around for this?

• Is possible to set generic type by another class?

  - by Soul_Master

  I use ASP.NET MVC for serving web application and I want to create something like the following code. <% using(HTML.Form(Model)) { %> <% HTML.CreateTextBox('txt1', x => x.Property1); <% } From the above code, Form extension method will receive object that represent type of current Model object in current View page. Next, CreateTextBox method will receive type from Form method and I can bind textbox to some property of this model. Update 1 The following code is code of CreateTextBox method that will create instance of TextBox class. public static CreateTextBox(string value, Expression<Func<object>> bindedProperty) { // T should be receive from HTML.Form method or class return new TextBox<T>(value); } Is it possible to creating some code that doing something like the above code?

• Programming terms - field, member, properties (C#)

  - by Petr

  Hi, I was trying to find meaning of this terms but especially due to language barrier I was not able to understand what they are used for. I assume that "field" is variable (object too?) in the class while "property" is just an object that returns specific value and cannot contain methods etc. By "member" I understand any object that is declared on the class level. But these are just my assumptions based on commented code samples where some careful programmers used "property region" etc. I would really appreciate if someone could explain it to me.

• Firefox 3.03 and contentEditable

  - by Ash

  I'm using the contentEditable attribute on a DIV element in Firefox 3.03. Setting it to true allows me to edit the text content of the DIV, as expected. Then, when I set contentEditable to "false", the div is no longer editable, also as expected. However the flashing caret (text input cursor) remains visible even though the text is no longer editable. The caret is now also visible when I click on most other text in the same page, even in normal text paragraphs. Has anyone seen this before? Is there any way to force the caret hidden? (When I either resize the browser or click within another application, and come back, the caret magically disappears.)

• how to calculate the beginning of a day given milliseconds?

  - by conman

  i want to figure out the time from the beginning of the day given a days milliseconds. so say i'm given this: 1340323100024 which is like mid day of 6/21/2012. now i want the milliseconds from the beginning of the day, which would be 1340262000000 (at least i think that's what it's supposed to be.) how do i get 1340262000000 from 1340323100024? i tried doing Math.floor(1340323100024/86400000) * 86400000 but that gives me 1340236800000, which if i create a date object out of it, says its the 20th. i know i can create a date object from 1340323100024, then get the month, year, and date, to create a new object which would give me 1340262000000, but i find it ridiculous i can't figure out something so simple. any help would be appreciated. btw, i'm doing this in javascript if it makes any difference.

• knockout.js with optionsValue and value

  - by Mike Flynn

  Is there a way to keep the value binding to the object, but have the optionsValue be a property on the object. As of now if I specify both, the optionsValue property that is selected will populate the value binding. Id like to keep the object intact in the observable, but specify what value to be set in the select list value. This way a form submit will send the optionsValue I chose. @Html.DropDownListFor(q => q.DivisionId, new SelectList(Enumerable.Empty<string>()), new { data_bind="options: divisions, optionsText: 'Name', optionsValue: 'Id', value: division, optionsCaption: ' - '" }) function AddCrossPoolGameDialog() { var self = this; self.divisions = ko.observableArray([]); self.division = ko.observable(); self.awayDivisionTeams = ko.computed(function () { var division = ko.utils.arrayFirst(self.divisions(), function(item) { return self.division.Name() == item.Name; }); if (division) { return division.DivisionTeamPools; } return []; }); }
