  • Can I use Linq to project a new typed datarow?

    - by itchi
    I currently have a csv file that I'm parsing with an example from here: http://alexreg.wordpress.com/2009/05/03/strongly-typed-csv-reader-in-c/ I then want to loop the records and insert them using a typed dataset xsd to an Oracle database. It's not that difficult, something like: foreach (var csvItem in csvfile) { DataSet.MYTABLEDataTable DT = new DataSet.MYTABLEDataTable(); DataSet.MYTABLERow row = DT.NewMYTABLERow(); row.FIELD1 = csvItem.FIELD1; row.FIELD2 = csvItem.FIELD2; } I was wondering how I would do something with LINQ projection: var test = from csvItem in csvfile select new MYTABLERow { FIELD1 = csvItem.FIELD1, FIELD2 = csvItem.FIELD2 } But I don't think I can create datarows like this without the use of a rowbuilder, or maybe a better constructor for the datarow?

  • jQuery plugin to have Facebook styled search box with image thumbnails?

    - by Michael Mao

  • Ruby on Rails - Calendar Display

    - by user335725
    We want to create a calendar view in a room scheduling application. The outcome we want is to have hours open (variable depending on day) across the top of the grid and the names of the rooms down the left side of the grid. The body would be populated with bookings for that day. The visual we're seeking is similar to the "Weekly Builder" plugin for Rails (http://dmix.ca/2009/06/weeklybuilder-a-weekly-calendar-plugin-for-rails/). We've tried using CSS to create variably-sized images, but this isn't working out. Are there any plugins available or other ways anyone can think of to accomplish this kind of visual? Thanks

  • How do I handle freeing unmanaged structures on application close?

    - by LostKaleb
    I have a C# project in which i use several unmanaged C++ functions. More so, I also have static IntPtr that I use as parameters for those functions. I know that whenever I use them, I should implement IDisposable in that class and use a destructor to invoke the Dispose method, where I free the used IntPtr, as is said in the MSDN page. public void Dispose() { Dispose(true); GC.SuppressFinalize(this); } private void Dispose(bool disposing) { // Check to see if Dispose has already been called. if (!this.disposed) { if (disposing) { component.Dispose(); } CloseHandle(m_InstanceHandle); m_InstanceHandle = IntPtr.Zero; disposed = true; } } [System.Runtime.InteropServices.DllImport("Kernel32")] private extern static Boolean CloseHandle(IntPtr handle); However, when I terminate the application, I'm still left with a hanging process in TaskManager. I believe that it must be related to the used of the MarshalAs instruction in my structures: [StructLayout(LayoutKind.Sequential, CharSet = CharSet.Ansi)] public struct SipxAudioCodec { [MarshalAs(UnmanagedType.ByValTStr, SizeConst=32)] public string CodecName; public SipxAudioBandwidth Bandwidth; public int PayloadType; } When I create such a structure should I also be careful to free the space it allocs using a destructor? [StructLayout(LayoutKind.Sequential, CharSet = CharSet.Ansi)] public struct SipxAudioCodec { [MarshalAs(UnmanagedType.ByValTStr, SizeConst=32)] public string CodecName; public SipxAudioBandwidth Bandwidth; public int PayloadType; ~SipxAudioCodec() { Marshal.FreeGlobal(something...); } }

  • What object called a method in Obj-C

    - by Loz
    Hi, I am looking to write a plugin controller in Cocoa that loads bundles, and exposes a specific set of methods for the plugins to call. My question is this: is it possible to know (any) info about the object that called a method in the controller. When an instantiated plugin calls a method in my plugin controller, I would like to know which of the plugin instances called the method, without having to rely on the plugin sending a pointer to itself as a parameter (I could always validate the pointer they send, but I want to keep the API methods as simple as possible). There may be no perfect solution (and there are simple workarounds), but it's always good to learn some new tricks if possible (or the reasons why it's impossible). Thanks in advance.

  • Detecting support for a given JavaScript event?

    - by Will
    I'm interested in using the JavaScript hashchange event to monitor changes in the URL's fragment identifier. I'm aware of Really Simple History and the jQuery plugins for this. However, I've reached the conclusion that in my particular project it's not really worth the added overhead of another JS file. What I would like to do instead is take the "progressive enhancement" route. That is, I want to test whether the hashchange event is supported by the visitor's browser, and write my code to use it if it's available, as an enhancement rather than a core feature. IE 8, Firefox 3.6, and Chrome 4.1.249 support it, and that accounts for about 20% of my site's traffic. So, uh ... is there some way to test whether a browser supports a particular event? Thanks.

  • How do I write a Photoshop Extension (8BX) plugin?

    - by Oliver Ahul
    The Adobe Photoshop CS3/4 SDk has a lot of examples for Filter, Import, Export etc plugins but I havent found anything that illustrates how to write a 8BX plugin. Reason I need to write one is to add a new drop down menu to the Photoshop root toolbar (where it displays File, Edit, Image .. Window. Help drop down menus). I have seen product like OneSoftware install an 8BX plugin into Adobe Photoshop CS3\Plug-Ins\Extensions directory that causes PS to add adrop down menu for OneSoft. That suggest this is a solvable problem :-) I tried by changing an existing plugin in the SDlK samples but no go. Specifically i modified the resource file: resource 'PiPL' (ResourceID, plugInName " PiPL", purgeable) { { Kind { **Extension** }, Name { plugInName "..." }, ... Despite using the Extension Kind , PS never loads the plugin. It doesnt generate any compile time or load error either. Anyone has ideas on how to go about doing this ? Thanks

  • How do I modify a string printed by a script?

    - by Liso22
    I'm having problems with wordpress mishandling accented characters, or maybe the problem is with some plugin. Whichever the case I need to "translate" some strings, removing accents which i do with: $value = strtr($value, $trans); I really need to change this string which renders the user's location but it's printed with a script so I have no idea how to do it: <script language="javascript"> document.write('' + geoip_city() +''); </script> Is there a way to assign it's result to a php value beforehand or something? Maybe removing the accents with a script. I really need to modify it, how could I manage to do it? Thanks

  • Java Authenticator on a per connection basis?

    - by Martijn Laarman
    I'm building an Eclipse plugin that talks to a REST interface which uses Basic Authentication. When the authentication fails I would like to popup my plugin's settings dialog and retry. Normally I could use the static Authenticator.setDefault() to setup an authenticator for all HttpURLConnection's for this, but since I am writing a plugin I don't want to overwrite Eclipse's default Authenticator (org.eclipse.ui.internal.net.auth); I thought of setting my custom Authenticator before loading and putting Eclipse's default back afterwards, but I imagine this will cause all sorts of race issues with multithreading so I quickly lost that notion. Google searches yield all sorts of results basically telling me it's not possible: The Java URLConnection API should have a setAuthenticator(Authenticator) method for making it easier to use this class in multi-threaded context where authentication is required. Source If applications contains few third party plugins and each plugin use its own Authenticator what we should do? Each invocation of "Authenticator.setDefault()" method rewrite previously defined Authenticator... Source Are there any different approaches that might help me overcome this issue?

  • User-customizable rails authorization

    - by neutrino
    Hello everyone, Seems there is an abundance of popular declarative-style authorization plugins, which allow you to somehow state in the code that, e.g., this controller action can be accessed by users with such-and-such roles. But what if I need a more dynamic scheme. I want to have an admin area, with a list of all authorizable actions and an ability to assign permissions on actions from the UI. I have ideas how to implement it from scratch, like to define a model corresponding to a controller and/or action and store the permissions via normal associations. Just wonder if there are any ready solutions to this. Thanks a lot

  • Converting a 16 bit tiff file to something viewable online?

    - by msandbot
    I need to take a 16 bit .tiff file and make it viewable on my website. To even view .tiff files many browsers require plugins. I found a software that could convert them to .jpg files but I was wondering if there is a way to do this independently. I am making my website using Ruby on Rails. I must be able to do the conversion from the website because the whole point of the website is to upload large folders of .tiff files and display them in an online slideshow. Any help would be appreciated. Thanks!

  • Building a J2EE dev/test setup on a single PC

    - by John
    It's been a while since I did Java work, and even then I was never responsible for starting a large project from the very start... there were test/staging/production systems already running, etc, etc. Now I am looking to start a J2EE project from scratch on my trusty workstation, which has never been used for Java development and runs Windows 7 64bit. First of all, I'll be getting Eclipse. As far as writing the code goes I'm pretty happy. And running it through Eclipse is OK, but what I'd really want is to have a VM running MySQL and TomCat on which I can properly deploy my project and run/debug it 'remotely' from my dev PC. And I guess this should be done using Ant instead of letting Eclipse build the WAR for me, so that I don't end up with a dependence on Eclipse. I'm certain Eclipse can do this, so you hit a button and it runs Ant scripts, deploys and debugs for instance, but very hazy on it. Are there any good guides on this? I don't want to be taught Java, or even Ant, but rather the 'glue' parts like getting my test VM up and running under Windows, getting a build/test/deploy/run pipeline running through Eclipse, etc. One point, I only plan to use Windows... hosting a Windows VM on my Windwos desktop. And while I can use command-line tools like ant/svn, I'm much more a GUI person who loves IDE integration... I'd rather this didn't end up an argument about Linux or Vi, etc! I am looking for free, but am a MAPS subscriber, and run Win7 Ultimate in case that makes a difference as far as free VM solutions.

  • .htaccess redirect question

    - by russp
    I have a slight problem with .htaccess redirect. I have a dynamic site with 2 levels of variables - content="type -(alpha)" and ID="number" but this is very not seo friendly what I really would like to create is a rewrite rule that generates a "friendly" url for serach engines & users alike. Very much like WordPress does. Each ID is already unique (obviously) and on creation is creating a unique "permalink" field so for example ID=1 has a "permalink field" as "2009/10/27/page title" and ID=100 would be "2010/10/27 page title". I would like folder/wall.php?content=type&ID=number to redirect to folder/permalink.php/html/htm (don't mind a non dynamic extension) Any clues? - this is not right (I know) but it also "breaks" my css file RewriteEngine On RewriteRule wall/content/(.*)/ID/(.*)/ wall.php?content=$1&ID=$2 RewriteRule wall/content/(.*)/ID/(.*) wall.php?content=$1&ID=$2

  • Subprocess statement works in python console but not work in Serverdensity plugin?

    - by maxigs
    in the python console the following statement works perfectly fine (i guess using eval that way is not really good, but its just for testing purpose in this case and will be replaced with proper parsing) $ python >>> import subprocess >>> r = subprocess.Popen(['/home/kupferwerk/sd-agent-plugins/plugin1.rb'], stdout=subprocess.PIPE, close_fds=True).communicate()[0] >>> data = eval(r) >>> data {'test': 1} when i convert this into a Serverdensity plugin however it keeps crashing the agent.py daemon everytime it executes the plugin. i was able to narrow it down to the subprocess line but could not find out why. exception catching did not seem to work also. here how the plugin looks like: class plugin1: def run(self): r = subprocess.Popen(['/pathto/plugin1.rb'], stdout=subprocess.PIPE, close_fds=True).communicate()[0] data = eval(r) return data I'm quite new to work with python and cant really figure out why this wont work. Thanks a lot for ideas :)

  • Zend Studio 7.1 PHPUnit Test Case wizard does not populate "Element to Test"

    - by Mike
    When I follow the instructions in ZS documentation to create a phpunit test case, the wizard returns no objects to select on the "Element to Test" line. Selecting "browse" provides an empty dialog box. The PHPUnit path in my preferences shows "/Applications/zend/zs710/plugins/com.zend.php.phpunit_7.1.0.v20091120-0900/resources/library/". What else can I check to see why I cannot create a test case? I'm new to ZS and PHP, so I have no idea how to troubleshoot this. Thanks.

  • Reading PDF form field data from Flex 4 ( via php or coldfusion )

    - by Brian Russel Davis
    Been searching web for an answer for this for a MONTH. I am not an expert in Coldfusion. So supposedly this is easy in CF -- but the mark-up confuses the HECK out of me. So here I am. I have managed to import and read a PDF using the CF Proxy for Actionscript: http://forums.adobe.com/thread/754629?tstart=0 --- BUT --- After all my trouble there, the precious form filed information that I was looking for was not there in the PDF info object. GRRRR. So I am back to looking for a way to do this with CFC's or CFM's or PHP. All I want is this: Read the PDF from a Flex app. GET the form field information. WRITE a new PDF with the form field values. I have found so many close but no cigar options ... and I have tried so many that failed. There are so many free PDF this and that out there. But Adobe seems to reserve the real functionality for themselves. All the free options don't seem to have access to the form data? Anyways I am so exhausted with looking for ways to do this. I need help!

  • How do you handle multiple (overlapping) projects in trac?

    - by Oliver Giesen
    We are using trac and are really satisfied with it. However, out of the box, trac is best suited for single-project environments only. I'd be interested to hear about the various approaches people take to make it work with multiple projects nevertheless and their experiences with them. Are there any plugins to recommend? Any patches, tweaks or whatnots? Are you maybe even using an entirely different bug-tracking system that offers all of trac's functionality plus multi-project support? We recently started managing a second project ourselves which generally works okay but also has some drawbacks, especially where the two projects overlap because of common library code we wrote that is used in both projects. How do you handle this? (I'll attach our own current approach as an answer to this post.)

  • Getting started developing for iPhone

    - by mikemoosey
    Hey all, quick question. My end goal is to start developing apps for the iPhone but my current skillset is pretty limited. I'm wondering how far back I should go back and where I should start as far as becoming familiar with coding before the iPhone SDK course on Lynda.com isn't something that makes my eyes glaze over. My experience: I taught myself html from the html for dummies book maybe 10 years ago, I've taken a dreamweaver class and built a few sites with it, and I've customized a self hosted Wordpress blog by playing with the php code. Any tips on where I should start if I want to head down the road toward developing for the iPhone? Thanks!

  • Support for multiple domains/subdomains in Rails

    - by thefactor
    I have a Rails app that has a similar setup to Tumblr, that is, you can have either: (1) Subdomain hosting (your-username.myapp.com) (2) Domain hosting (your-username.com) Both would forward to a personalized website for that user, created with my application. How can I accomplish this in Rails? I have been able to get (1) working with subdomain-fu, but I'm not sure how to get (2) working. Any pointers (plugins, gems, tutorials), etc. would be greatly helpful, I can't seem to find any. Thanks!

  • How do you extend a Ruby module with macro-like metaprogramming methods?

    - by Ian Terrell
    Consider the following extension (the pattern popularized by several Rails plugins over the years): module Extension def self.included(recipient) recipient.extend ClassMethods recipient.class_eval { include InstanceMethods } end module ClassMethods def macro_method puts "Called macro_method within #{self.name}" end end module InstanceMethods def instance_method puts "Called instance_method within #{self.object_id}" end end end If you wished to expose this to every class, you can do the following: Object.send :include, Extension Now you can define any class and use the macro method: class FooClass macro_method end #=> Called macro_method within FooClass And instances can use the instance methods: FooClass.new.instance_method #=> Called instance_method within 2148182320 But even though Module.is_a?(Object), you cannot use the macro method in a module: module FooModule macro_method end #=> undefined local variable or method `macro_method' for FooModule:Module (NameError) This is true even if you explicitly include the original Extension into Module with Module.send(:include, Extension). How do you add macro like methods to Ruby modules?
