• cross domain access in iframe from parent to child

  - by Aparna

  Hi, Could someone please help me with this- I've 2 applications AAA and BBB. The homepage of AAA contains an iFrame which displays the application BBB. When I login to AAA, the same login details should be used to login to BBB(single signon) and on pageload of the homepage of AAA, homepage of BBB should also be loaded in the iFrame. I tried to use javascript to access the form elements of login page of BBB to enter the login data and submit. But the browser gives me a 'Access is denied' error. I did a little reading and came to know that cross- domain communication is not allowed by the browser. Could someone tell me how i can go about achieving this?

• 'sript/console test' with spork and rspec not loading the whole environment?

  - by TheDeeno

  I'm trying to load up console to interact with some of my rspec mocking helpers. I expected that running script/console test would load an env similar to when I run spec. However, this doesn't appear to be the case. It looks like spec_helper is never loaded. Or, if it is, it's not actually running through the logic because spork has polluted it a bit. In short, is there a quick and easy way to get an interactive rspec party going?

• How can I implement forum privileges

  - by RobertPitt

  I've started developing a forum application in PHP on my MVC Framework and I've got to the stage where I assign permissions to members (for example: READ, WRITE, UPDATE, DELETE). Now, I know I can add 5 columns under the user table in my database and set them to 1 | 0, but that to me seems like too much if I want to add other rules, like MOVE for example. And how can I dynamically assign these privileges them to users individually? I've heard of using a bitmasks, but it would be really good if I could fully understand them before I continue. Do you have an example of how I might implement this?

• "Could not load file or assembly" error on trying to access auxillary assemblies from COM

  - by Codex

  We have the project structure as follows: COMExposedCCW.dll -refers- BusinessLayer.dll -refers- Utils.dll COMExposedCCW.dll -refers- Utils.dll The COMExposedCCW.dll has been registered for COM interop. From the COM application{Excel} we can successfully create the CCW object and access its properties, but when we try to invoke methods that refer to the Business/Utils layer, it throws an exception that the file or assembly{Business/Utils} could not be found. The Business/Utils dlls are present in the same folder as the CCW. On copying the Business/Utils to the COM application directory it works fine. I've tried the following: Set "HintPath/" in the CCW project I dont want to dynamically load the assemblies using Reflection {there should be a more elegant solution} Thanks in advance.

• How does this ruby custom accessor work

  - by ennuikiller

  So the method below in class_eval dynamically creates accessors for attributes defined at runtime. It can be used, for example, to create configuration objects with attributes read from a config file (and unknown until runtime). I understanding all of it except for the else branch. If I am correct the else branch returns the attribute value (val[0]) if there is one value passed in *val. However the way its written I would expect it to return an array (val) if there is more then one value passed in *var. In particular, if I have something like the following: value = 5 then from reading the code I would expect "#{@value}" to be [=,5]. However "#{@value}" returns 5 and not the array [=,5]. How is this possible? class Module def dsl_accessor(*symbols) symbols.each do |sym| class_eval %{ def #{sym}(*val) if val.empty? @#{sym} else @#{sym} = val.size == 1 ? val[0] : val end end } end end end

• Using LaTeX, how can I have a list of references at the end of each section?

  - by celenius

  I want to generate the bibliography for each section, and have it at the end of the section. When I do this at the moment it generates the full bibliography and places it after each section. Is there a way that this can be done? The advice here says "The chapterbib package provides an option sectionbib that puts the bibliography in a \section* instead of \chapter*, something that makes sense if there is a bibliography in each chapter. This option will not work when natbib is also loaded; instead, add the option to natbib. " I don't understand what this means, and I've tried experimenting with what I thought the options are. Specifically, what does "add the option to natbib" mean? Thank you for your help.

• IE8 won't load JavaScript file in "Compatibility View."

  - by Don Jones

  Here's my JS insert: <script type="text/javascript" src="include/profile.js"></script> In IE8 with "Compatibility View," the file never loads. The first line in the file is a simple alert() call, so that I know it loaded. Change the browser to Standards View, and it loads fine. Also, if I add: <meta http-equiv="X-UA-Compatible" content="IE=100" > It forces to Standards View and it loads fine. Any idea why this would be the case? I've not been able to test against IE7, but I know the JS file also does not load in IE6. Right now the tag is in the section of the file.

• (iPhone SDK) How to link instance variables to a specific UILabel

  - by Timbo

  I'm using the iPhone SDK to build a simple application. I've created a brand new class which has a single variable. I need to make 5 instances of that class, which I have no trouble doing. I can create those instances and also set the variables without issue. What i do need to know is this: How do I link each of the 5 different instances of the variable to different and specific UILabels? Would I be better to create a method that dynamically creates and positions the labels? Thanks for your help in advance, I'm now to this iphone programming thing. I'm serious about learning fast though so I have posted a bounty on this question here : http://www.askearn.com/Responses.aspx?QuestionID=6542613f-7be8-4bb3-a950-aac218d47711

• Merging columns in a JTable

  - by Harish

  I am working in JTable and I have a requirement like this. Say There are 4 columns namely 10,20,30,40 Now the value usually comes like 10-20 20-30 and 30-40 So it was easy for us to display the name for this range. But recently the values have started to come randomly like 15-25 10-25,25-30 In this case our JTable should dynamically adjust the size of the row such that it represents that range only meaning it should not disturb the existing cells and only rows which diverge from the normal range. TO be more precise I should be able to merge and split cells based on the content of the cell.

• How to add text to path?

  - by Pritorian

  Hi all. Te question is how to add text to path element. For example, I have path: Path firstPath = new Path(); firstPath.Stroke = Brushes.Black; firstPath.StrokeThickness = 1; myCanvas.Children.Add(firstPath); LineGeometry firstLine = new LineGeometry(); firstPath.Data = firstLine; And somewhere I define line's Start and End point's. The path is binded to controls (for example - two ellipses) and when I drag one of them, the line is dynamically resized and moved to be pinned to both objects. And now I wand to add some text, that would fit to this line and follow it. Any recommendations how to do this?

• Web Crawling Sites with Javascripts or web forms

  - by Jojo

  Hello everyone, I have a webcrawler application. It successfully crawled most common and simple sites. Now i ran into some types of websites wherein HTML documents are dynamically generated through FORMS or javascripts. I believe they can be crawled and I just don't know how. Now, these websites do not show the actual HTML page. I mean if I browse that page in IE or firefox, the HTML code does not match what's actually in the IE or firefox. These sites contain textboxes, checkboxes, etc... so I believe they are what they call "Web Forms". Actually I am not much familiar with web development so correct me if I'm wrong. My question is, does anyone in similar situation as I am now and have successfully solved these types of "challenges"? Does anyone know of a certain book or article regarding web crawling? Those that pertains to these advanced type of websites? Thanks.

• SlideDown then call custom function

  - by user275074

  Hi, Having difficulty understanding why my function is being called twice. I'm trying to detect when a radio button is called (intRev_yes), check if a div is empty, slide down another div and then call a custome function which dynamically creates a date field. if(this.id=="intRev_yes"){ if($('div#mainField').is(':empty')){ $('.intRevSections').slideDown('slow',function(){ current=-1; addIrField(); }); } } When I alert out at each stage, after getting to the end (i.e. addIrField()), the script seems to go back to the slideDown() section and recalls addIrField(). I can't understand why, there are no loops. current is used as an index for the date field.

• Making GWT application crawlable by a search engine.

  - by Philippe Beaudoin

  I want to use the #! token to make my GWT application crawlable, as described here: http://code.google.com/web/ajaxcrawling/ There is a GWT sample app available online that uses this, for example: http://gwt.google.com/samples/Showcase/Showcase.html#!CwRadioButton Will serve the following static webpage to the googlebot: http://gwt.google.com/samples/Showcase/Showcase.html?_escaped_fragment_=CwRadioButton I want my GWT app to do something similar. In short, I'd like to serve a different flavor of the page whenever the _escaped_fragment_ parameter is found in the URL. What should I modify in order for the server to serve something else (a static page, or a page dynamically generated through a headless browser like HTML Unit)? I'm guessing it could be the web.xml file, but I'm not sure. (Note: I thought of checking the Showcase app provided with the GWT SDK, but unfortunately it doesn't seem to support serving static files on _escaped_fragment_ and it doesn't use the #! token..)

• Window 'onscreen' size puzzle

  - by Bender

  Okay, a REALLY fundamental question about window sizes here... If I create an NSWindow in IB, set its size to 216 x 144 points (exactly 3 inches by 2 inches) then print the window, it measures exactly what I set it to in IB. However, the onscreen display size measures approximately 156 x 105 points. What causes this, and is there any way to force the window to display at the required size onscreen? I ultimately want to draw to this (semi-transparent) window then use it as a full-sized overlay for comparison against a separately loaded scanned image of known size.

• How to stop java application using a shell script

  - by Fernando Moyano

  I have a shell script, which is run under a opensuse linux, that starts a java application (under a jar), the script is: #!/bin/sh #export JAVA_HOME=/usr/local/java #PATH=/usr/local/java/bin:${PATH} #---------------------------------# # dynamically build the classpath # #---------------------------------# THE_CLASSPATH= for i in `ls ./lib/*.jar` do THE_CLASSPATH=${THE_CLASSPATH}:${i} done #---------------------------# # run the application # #---------------------------# java -server -Xms512M -Xmx1G -cp ".:${THE_CLASSPATH}" com.package.MyApp > myApp.out 2>&0 & This script is working fine. Now, what I want, is to write a script to kill gracefully this app, something that allows me to kill it with the -15 argument from Linux kill command. The problem, is that there will be many java applications running on this server, so I need to specifically kill this one. Any help? Thanks in advance, Fernando

• Adding a dynamic-height UITableView into a scrolling view?

  - by Greg

  Hello all – I'm getting into iPhone development and have hit my first confusing UI point. Here's the situation: My app is tab-based, and the view that I'm confused about has a static featured content image at the top, then a dynamic list below into which X headlines are loaded. My goal is to have the height of the headline table grow as elements are added to it, and then to have the whole view scroll (both featured image on top and headline list below). So, I guess my question comes in two parts: 1) First, how do you set up a dynamic-height table view that will grow as cells are added to it. So far I've only been able to have my tables handle their own scrolling. 2) Then, what is the root NIB view that the featured image and the table should live in to enabled scrolling? I've dropped oversized content into a UIScrollView now, although did seem to have any success with having it automatically scroll. Thanks in advance for any help on this subject!

• Adding Parameters to Zend_Navigation

  - by Grant Collins

  I have a problem with Zend_Navigation that I am hoping for a little guidance on. I'm in the process of adding a Zend_Navigation to a legacy app as described [here on SO].1 The thing that I am not sure of is how to add parameters to the navigation menu after the data is loaded from the xml file. What I want to do is get 2 identifying parameters from the url and add them to the Zend_Navigation so that they are included in things such as the breadcrumb bar, so that if a user selects the previous item in the breadcrumb they are returned with the correct params in the url. The parameters, I believe need to be set at the Action level rather than the controller. Any help would be appreciated. Many thanks.

• grails metaprogramming

  - by Don

  Hi, My understanding is that there are two obvious places in a Grails app where one can do meta-programming: The init closure of Bootstrap.groovy The doWithDynamicMethods closure of a plugin The meta-programming I'm referring to here should be visible throughout the metaprogramming, typical examples include adding (or replacing) methods of 3rd party classes. String.metaClass.myCustomMethod = { /* implementation omitted */ } The disadvantage of (1), is that the metaprogramming won't be applied when the application is dynamically reloaded. The disadvantage of (2) is that I need to create and maintain an entire plugin just for the sake of a little metaprogramming. Is there a better place to do this kind of metaprogramming? Thanks, Don

• Jquery (or CSS) autoresize iframe to the bottom?

  - by mathiregister

  Hi guys, i've no idea how i can set properties for an iframe that's positioned 300px from the top, but should reach ALWAYS the bottom! So at the moment i've set the height of the iframe to 500px. The height should dynamically change when i resize the browserwindow. The iframe should start 300px from the top and should always reach the bottom. I'm not much of an css expert. Any idea what i have to do? #frame { overflow:hidden; border:none; width:100%; height:500px; margin-top:300px; }

• Passing switches to Xcode 3.1 user scripts

  - by MyztikJenz

  I have a user script that would be much more useful if it could dynamically change some of its execution dependent on what the user wanted. Passing simple switches would easily solve this problem but I don't see any way to do it. I also tried embedding a keyword in the script name, but Xcode copies the script to a guid-looking filename before execution, so that won't work either. So does anyone know of a way to call a user script with some sort of argument? (other that the normal %%%var%%% variables) Thanks! EDIT: User scripts are accessible via the script menu in Xcode's menubar (between the Window and Help menus). My question is not about "run script" build phase scripts. My apologies for leaving that somewhat ambiguous.

• Best placement for javascript in Asp.net MVC app that heavily uses partial views

  - by KallDrexx

  What is the best place for javascript that is specific to a partial view? For example, if I have a partial view (loaded via ajax call) with some divs and I want to turn those divs into an accordian, would it be better put the $("#section").accordion() in script tags inside of the partial view, or in a .js file in the function that retrieves that partial view and inserts it into the DOM? Obviously, common methods I will be keeping in a .js file, however I am more talking about javascript very specific to the partial view itself. Most things I find on the net seem to say to put all javascript into a separate .js but nothing addresses the idea of partial views.

• Replacement for PHP's __autoload function?

  - by Josh

  I have read about dynamically loading your class files when needed in a function like this: function __autoload($className) { include("classes/$className.class.php"); } $obj = new DB(); Which will automatically load DB.class.php when you make a new instance of that class, but I also read in a few articles that it is bad to use this as it's a global function and any libraries that you bring into your project that have an __autoload() function will mess it up. So does anyone know of a solution? Perhaps another way to achieve the same effect as __autoload()? Until I find a suitable solution I'll just carry on using __autoload() as it doesn't start becoming a problem until you bring in libraries and such. Thanks.

• Select dynamic string has a different value when referenced in Where clause

  - by David

  I dynamically select a string built using another string. So, if string1='David Banner', then MyDynamicString should be 'DBanne' Select ... , Left( left((select top 1 strval from dbo.SPLIT(string1,' ')) //first word ,1) //first character + (select top 1 strval from dbo.SPLIT(string1,' ') //second word where strval not in (select top 1 strval from dbo.SPLIT(string1,' '))) ,6) //1st character of 1st word, followed by up to 5 characters of second word [MyDynamicString] ,... From table1 Join table2 on table1pkey=table2fkey Where MyDynamicString <> table2.someotherfield I know table2.someotherfield is not equal to the dynamic string. However, when I replace MyDynamicString in the Where clause with the full left(left(etc.. function, it works as expected. Can I not reference this string later in the query? Do I have to build it using the left(left(etc.. function each time in the where clause?

• Creating a customized video using Flash and XML

  - by Aaron Ladage

  The problem: I have to create a Flash video (in CS3) that will query a MySQL database and display that data at certain points in the video. The bigger problem: I'm not a Flash/ActionScript developer, so this is all very foreign to me! I've divided this project into two parts: a.) dynamically generate an XML feed from the data using PHP (using an ID number passed in the URL's query string), and b.) be able to work with it in Flash. I've got the first part working, but am pretty lost in Flash. I can parse the XML, but I'm not sure how to set the data up as variables and attach it to a video's cue points. Can anyone point me in the direction of a good tutorial or offer some advice?
