• firefox: How to enable local javascript to read/write files on my PC?

  - by Nok Imchen

  well, since greasemonkey cant read/write files from local hard disk. I've heard people suggesting Google gears but i've no idea obout gears :( So, what i've decided is to add a script type="text/javascript" src="file:///c:/test.js"/script Now, this test will use FileSystemObject to read/write file. Since, the "file:///c:/test.js" is a javascript file from local hard disk, so it should probable be able to read/write file on my local hard disk. I tried it but firefox prevented the "file:///c:/test.js" script to read/write files from local diak :( What i want to know is: Is there any setting in firefox about:config where we can specify to let a particular script, say from localfile or xyz.com, to have read/write permission on my local disk files??

• Shadow volume shader optimization (GLSL)

  - by Soubok

  I wondering if there is a way to optimize this vertex shader. This vertex shader projects (in the light direction) a vertex to the far plane if it is in the shadow. void main(void) { vec3 lightDir = (gl_ModelViewMatrix * gl_Vertex - gl_LightSource[0].position).xyz; // if the vertex is lit if ( dot(lightDir, gl_NormalMatrix * gl_Normal) < 0.01 ) { // don't move it gl_Position = ftransform(); } else { // move it far, is the light direction vec4 fin = gl_ProjectionMatrix * ( gl_ModelViewMatrix * gl_Vertex + vec4(normalize(lightDir) * 100000.0, 0.0) ); if ( fin.z > fin.w ) // if fin is behind the far plane fin.z = fin.w; // move to the far plane (needed for z-fail algo.) gl_Position = fin; } }

• IIS7 URL Rewrite with dynamic subdomains.

  - by arri.me

  My goal is to implement the following scheme using the subdomain and path as attributes: Use a wildcard DNS entry that routes any subdomain to the root site: Example: *.example.com ex: http://xyz.example.com to http://example.com Next I want to rewrite the requests to point to a specific page, passing both the subdomain and the request path as attributes. Example: http://xyz123.example.com/images/header.jpg to http://example.com/get.aspx?id=xyz123&path=/images/header.jpg I've seen several questions on here regarding similar goals, but not quite the same. I'm new to using rewrite rules, so any help is appreciated. I will update this as I make progress.

• How to implement eCommerce susbscription service with multiple products

  - by Todd Brooks

  I've been researching eCommerce payment gateways and service offerings, but I'm an eCommerce novice, so please excuse my ignorance. I wish to set up an eCommerce solution with the following requirements: User "subscribes" to the service on a yearly basis. This service includes a single product subscription for a set amount (let's say $50/yr). User can "subscribe" to additional product services for a lesser rate per year (let's say $25/yr). I will need to store a product service unique Id of some sort for each product subscription the user subscribes to in order to show them product unique information. I also need to prevent duplicates...for example, user can subscribe to product ABC and XYZ, but not 2 of ABC. Is PayPal the best solution for something like this? Is there a better solution? Any assistance is greatly appreciated, even if just links to specific tutorials or examples. Update: It looks like Chargify could be the perfect solution.

How to do this..?

• Test if a Property is not Null before Returning

  - by DaveDev

  I have the following property public MyType MyProperty {get;set;} I want to change this property so that if the value is null, it'll do populate the value first, and then return it... but without using a private member variable. For instance, if I was doing this: public MyType MyProperty { get { if (_myProperty != null) return _myProperty else _myProperty = XYZ; return _myProperty; } set { _myProperty = value; } } is this possible? Or do I need the member variable to get it done?

• How to debug a tcl script which is argument to an executable?

  - by user321047

  I have a application which takes tcl script as argument. I want to debug tcl script when the application processes it. My development environment consists of Dynamic Languages Toolkit from www.eclipse.org/dltk along with Active state remote debugger -dbgp_tcldebug. I am able to debug the individual tcl scripts with this setup. I created a tcl project in eclipse and added 'startup.tcl' and 'argumentScript.tcl' scripts and added following command to the startup script, set ExecutableName "xyz.exe" set returnValue [catch {eval exec $ExecutableName "argumentScript.tcl" } result] My debugger works fine with 'startup.tcl' script. I added the breakpoint in 'argumentScript.tcl' but it is not working. How can I debug the "argumentScript.tcl" script ? Edit: A solution without using eclipse environment is Tcl Dev Kit with remote debugging feature.

• Adding rows to UItableview and passing data between Viewcontrollers

  - by Jonathan

  I have a list of websites in a plist, when the app loads this populates a tableview (which is inside a navigation controller) But I have added an add button to the navigation bar and then created another View Controller to deal with inputting of the new website (Like Title and URL). It is very similar to how the contacts app looks. There is a table view and when you tap add, the add UI slides up. I have got all this working great so far. My Problem is what happens when the user taps Done. I can add the website to the plist (each website is a dictionary in the plist with 2 keys, atm) But then how do I tell the tableView to update? The table view has not been removed from the main window, just the add view has been added on top of the "screen". Another way of asking is, when you tap Save on Add a Contact screen: (not my image) How does the new contact's data (Xyz's data) get shown on the tableview?

• How to Test a Multi-Tenant App with support for multiple domains

  - by asifch

  HI, we are building a multi-tenant application, which will support that each tenant can have a unique top level domain, the application is build using the asp.net 3.5 and SQL servr 2005, while each tenant will have different database. I have seen a number of questions about the similar applications on the StackOverFlow, but none of them is related to the Testing, I want to know is how one can test the application in a development environment, specially How can we test that each customer connects to his own DB based on the URL. how can we emulate different domains on the local system. like abc.com and xyz.com all goes to dev machine's IIS. Any recommendations which might help us in the developing process of such an application.

• JDBC resultset close

  - by KM

  I am doing profiling of my Java application and found some interesting statistics for a jdbc PreparedStatement call: Given below is the environment details: Database: Sybase SQL Anywhere 10.0.1 Driver: com.sybase.jdbc3.jdbc.SybDriver connection pool: c3p0 JRE: 1.6.0_05 The code in question is given below: try { ps = conn.prepareStatement(sql); ps.setDouble(...); rs = ps.executeQuery(); ...... return xyz; } finally { try { if (rs != null) rs.close(); if (ps != null) ps.close(); } catch (SQLException sqlEx) { } } From JProfiler stats, I find that this particular resultspace.close() statement alone takes a large amount of time. It varies from 25 ms to 320s while for other code blocks which are of identical in nature, i find that this takes close to 20 microseconds. Just to be sure, I ran this performance test multiple times and confirmed this data. I am puzzled by this behaviour - Thoughts?

• linq2sql - where to enlist transaction (repository or bll)?

  - by Caroline Showden

  My app uses a business layer which calls a repository which uses linq to sql. I have an Item class that has an enum type property and an ItemDetail property. I need to implement a delete method that: (1) always delete the Item (2) if the item.type is XYZ and the ItemDetail is not null, delete the ItemDetail as well. My question is where should this logic be housed? If I have it in my business logic which I would prefer, this involves two separate repository calls, each of which uses a separate datacontext. I would have to wrap both calls is a System.Transaction which (in sql 2005) get promoted to a distributed transaction which is not ideal. I can move it all to a single repository call and the transaction will be handled implicitly by the datacontext but feel that this is really business logic so does not belong in the repository. Thoughts? Carrie

• Duplicate image with Haxe

  - by Johnny Oin

  Hello, My goal is to make a wide map using only one square image. Using actionscript 3 the solution is to simply make new Bitmap from the Loader: var loader:Loader = new Loader(); loader.load(new URLRequest("xyz.png")); this.addChild(loader); var duplicationBitmap:Bitmap = new Bitmap(Bitmap(loader.content).bitmapData); Unluckily, Haxe API doesn't allow to do that. I can't get bitmapData from loader content… Anyone has a clue? Thanks.

• Constructing dynamic columns from parameters in Sybase

  - by Chapax

  Hi, I'm trying to write a stored proc (SP) in Sybase. The SP takes 5 varchar parameters. Based on the parameters passed, I want to construct the column names to be selected from a particular table. The below works: DECLARE @TEST VARCHAR(50) SELECT @TEST = "country" --print @TEST execute("SELECT DISTINCT id_country AS id_level, Country AS nm_level FROM tempdb..tbl_books INNER JOIN (tbl_ch2_bespoke_report INNER JOIN tbl_ch2_bespoke_rpt_mapping ON tbl_ch2_bespoke_report.id_report = tbl_ch2_bespoke_rpt_mapping.id_report) ON id_" + @TEST + "= tbl_ch2_bespoke_rpt_mapping.id_pnl_level WHERE tbl_ch2_bespoke_report.id_report = 14") but gives me multiple results: 1 1 row(s) affected. id_level nm_level 1 4376 XYZ 2 4340 ABC I would like to however only obtain the 2nd result. Do I need to necessarily use dynamic SQL to achieve this? Many thanks for your help. --Chapax

• best practices for setting development environment

  - by Sharique

  I use Linux as primary OS. I need some suggestions regarding how should I set up my desktop and development. I do work on mostly .Net and Drupal, but some time on other lamp products and C/C++, Qt. I'm also interested in mobile (android..) and embedded development. Currently I install everything on my main OS, even I use it a little. I use VMs a little. Should I use separate VM for each kind of development (like one for .Net/Mono, another C++, one for mobile and one for db only, one for xyz things etc) Keep primary development environment on main os and moveothers in VM. main os should be messed up keep things easy to organize (must) performance should be optimal

• Global Handler in IIS7 (Classic Mode) gives "Failed to Execute" error

  - by Akash Kava

  I have made a custom handler called MyIndexHandler and I want it to handle *.index requests, now as I want this handler to be executed by any website, I installed my handler with following two steps in IIS manager. Add MyIndexHandler.dll in GAC Add Managed Module for *.index, the drop down in IIS displays my index handler correctly so it means it did find it correctly from the GAC. I added Script map for aspnet_isapi.dll for *.index (this is required for classic mode) Now in any of my website if I try xyz.index, my handler does not get called and it returns "Failed to execute URL", now this only happens when IIS is unable to find the mapped handler, but I already have defined mapped handler at IIS level and when i try to add entry in web.config manually for this handler, it tells me you can not define multiple handler, it means that IIS finds my handler, mapping but for some reason it does not execute it.

• Change the get parameters in the address bar in jquery

  - by hao

  when you search on yelp, by adding additional search parameters the page does not reload. I think the results are changed based on ajax, however when you click on one of the restaruants and go back to the previous page. All of the parameters are still there. I noticed the address bars change as the parameters change. I found http://www.asual.com/jquery/address/ but it seems to add # at the end of the url. Is there a way to make it simply like index.php?xyz=1 without refreshing the page

• Artistic aspects of UI?

  - by anon

  Consider a single button. At one extreme, we have a black OpenGL window, with: outline (in white) of a rectangle bitmap remdered font inside of it, saying "Ok" At the other extreme, we have Mac OS X, a button that is: well rounded has some gradient showing light effects on it nice antialiased "OK" soft shadow of some sort These two UIs present very very different user experiences. The former says "This is from the 80s" the latter says "this is professional". This is something I do not understand well as a programmer (and don't know where to learn about this). Does anyone know of a good technical resource for this? [I'd prefer things that draws upon psychology / perception literature to say why to do something rather than design books that just says "use color XYZ with a gradient of blah"]

• Unit Testing Codeigniter Classes with fooStack - clashes

  - by DrPep

  I'm having 'fun' testing interactions in a CodeIgniter based web app. It seems when running the entire test suite "phpunit AllTests.php" it loads all of the test classes, their targets (Systems under Test) and creates a PHPUnit_Framework_TestSuite instance which presumably iterates over the classes which extend CIUnit_TestCase and runs them. The problem comes where you have multiple classes referencing another class (such as a library). As all the classes are loaded into the same process space, PHP reports "cannot redefine class xyz". Have I missed something here or doing something haenously wrong? In my test class i'm doing something like: include_once dirname(__FILE__).'/../CIUnit.php'; include_once dirname(__FILE__).'/../../libraries/ProductsService.php'; class testProductsService extends CIUnit_TestCase { public function testGetProducts_ReturnsArrayOfProducts(){ $service = new ProductsService(); $products = $service->getProducts(); $this->assertTrue(is_array($products)); } } The problem manifests as I have a controller which does: $this->load->library('ProductsService');

• Help in XPath expression

  - by Ashish Gupta

  I have an XML document which contains nodes like following:- <a class="custom">test</a> <a class="xyz"></a> I was tryng to get the nodes for which class is NOT "Custom" and I wrote an expression like following:- XmlNodeList nodeList = document.SelectNodes("//*[self::A[@class!='custom'] or self::a[@class!='custom']]"); Now, I want to get IMG tags as well and I want to add the following experession as well to the above expression:- //*[self::IMG or self::img] ...so that I get all the IMG nodes as well and any tag other than having "custom" as value in the class attribute. Any help will be appreciated. EDIT :- I tried the following and this is an invalid syntax as this returns a boolean and not any nodelist:- XmlNodeList nodeList = document.SelectNodes("//*[self::A[@class!='custom'] or self::a[@class!='custom']] && [self::IMG or self::img]");

• OpenGL Diffuse Lighting Shader Bug?

  - by anon

  The Orange book, section 16.2, lists implementing diffuse lighting as: void main() { vec3 N = normalize(gl_NormalMatrix * gl_Normal); vec4 V = gl_ModelViewMatrix * gl_vertex; vec3 L = normalize(lightPos - V.xyz); gl_FrontColor = gl_Color * vec4(max(0.0, dot(N, L)); } However, when I run this, the lighting changes when I move my camera. On the other hand, when I change vec3 N = normalize(gl_NormalMatrix * gl_Normal); to vec3 N = normalize(gl_Normal); I get diffuse lighting that works like the fixed pipeline. What is this gl_NormalMatrix, what did removing it do, ... and is this a bug in the orange book ... or am I setting up my OpenGl code improperly?
