• Office Automation Libraries

  - by Ian

  Some time ago I posted about a question about reading Excel files as a server process, to get around the tighter restrictions Microsoft have been applying on Office Automation. I now need to extend this, by finding methods/libraries to read other sorts of Office files in an automated way on a server. The applications I'm interested in are Word, Powerpoint, Project and to a lesser extent Word and Visio. I need to be able to support 97-2003 office files, and the newer open xml formats (e.g. xlsx, docx) at a very least. With regards to Word integration, I also need to be able to handle writing/reading RTF text. If anyone has any suggestions I'd be pleased to hear them. Thanks

• Stream a file to the HTTP response in Pylons

  - by Evgeny

  I have a Pylons controller action that needs to return a file to the client. (The file is outside the web root, so I can't just link directly to it.) The simplest way is, of course, this: with open(filepath, 'rb') as f: response.write(f.read()) That works, but it's obviously inefficient for large files. What's the best way to do this? I haven't been able to find any convenient methods in Pylons to stream the contents of the file. Do I really have to write the code to read a chunk at a time myself from scratch?

• Improving the speed of php

  - by cast01

  I'm currently working on a website in PHP, and I'm wondering what the best practices/methods are to reduce the time requests take. I've build the site in a modular way, so a page would consist of a number of modules, and each of these would need to request information. For example, I have a cart module, that (if a cart is set) will fetch the cart with the id (stored in a session variable) from the database and return its contents. I have another module that lists categories and this needs to fetch the categories from the database. My system is built with models, and each model might also make a request, for example a category model will make a request to get products in that category.

• GWT RPC - Does it do enough to protect against CSRF ?

  - by sri

  GWT's RPC mechanism does the following things on every HTTP Request - Sets two custom request headers - X-GWT-Permutation and X-GWT-Module-Base Sets the content-type as text/x-gwt-rpc; charset=utf-8 The HTTP request is always a POST, and on server side GET methods throw an exception (method not supported). Also, if these headers are not set or have the wrong value, the server fails processing with an exception "possibly CSRF?" or something to that effect. Question is : Is this sufficient to prevent CSRF? Is there a way to set custom headers and change content type in a pure cross-site request forgery method?

• Rails: Skinny Controller vs. Fat Model, or should I make my Controller Anorexic?

  - by Nick Gorbikoff

  I know similar questions have been answered before - such as: Where should logic go, where to do certain tasks, etc. But I have a more specific question - How far should I take this axiom: "keep your controller skinny, make your model fat!" Here is an example: For instance let's say I have multiple source of verification data. A good example would be a VIN number - I can verify it against, manufacturers data source, DMV's data source, also my local databases - to see what I have on record. So I have a model called Vin and vins_controller. Inside the model I have 5 methods: check_against_local_db, check_against_dmv, check_against_car_maker_1, check_against_car_maker_2, etc. In my controller keeping with the REST, in action show - I have a simple case statement which looks at the params[:source], and based on source specified - will call specific check method. Now here is the question: Should I leave the logic that governs which data source to call in controller or should I move it to model and then in controller just do something like check_vin(source, vin)? Should I make my controller anorexic?

• How to: WCF XML-RPC client?

  - by mr.b

  I have built my own little custom XML-RPC server, and since I'd like to keep things simple, on both server and client side, what I would like to accomplish is to create a simplest possible client (in C# preferably) using WCF. Let's say that Contract for service exposed via XML-RPC is as follows: [ServiceContract] public interface IContract { [OperationContract(Action="Ping")] string Ping(); // server returns back string "Pong" [OperationContract(Action="Echo")] string Echo(string message); // server echoes back whatever message is } So, there are two example methods, one without any arguments, and another with simple string argument, both returning strings (just for sake of example). Service is exposed via http. Aaand, what's next? :) P.S. I have tried googling around for samples and similar, but all that I could come up with are some blog-related samples that use existing (and very big/numerous) classes, which implement appropriate IContract (or IBlogger) interfaces, so that most of what I am interested is hidden below several layers of abstraction...

• Vimeo - videos.getChannels

  - by brad

  How can I efficiently retrieve a list of channels that a Vimeo video is listed in from the Advanced Vimeo API? The Advanced Vimeo API provides the methods channels.addVideo and channels.removeVideo for managing the channels a video belongs to. Also, the channels.getVideos method is provided for retrieving the list of videos belonging to a channel. However, there is no videos.getChannels method. This means that in order to find all the channels a video is included in one would need to call channels.getVideos (possibly more than once if the channel has more than 50 videos) for each channel of interest. This seems terribly inefficient.

• 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.

• How can I grab the iTunes-defined name for my iPhone/iPod device?

  - by Christophe Porteneuve

  Hey there, I'm trying to get the name for an iPhone/iPod device that the user entered in their iTunes. This is not, I repeat, not, necessarily what [[UIDevice currentDevice] name] returns (or any of its other methods). For instance, my iPhone is bound in iTunes to "iPhone 3G de Christophe…", to differentiate it from my wife's and other similar devices. That's the name I'd love to be able to grab. Is it stored anywhere on the device, and if so can I access it somehow? Thanks!

• How to make Date locale-independent? (GMT timezone newbie question)

  - by folone

  I have a db, that stores dates in OleDateTime format, in GMT timezone. I've implemented a class, extending Date in java to represent that in classic date format. But my class is locale-dependent (I'm in GMT+2). Therefore, it converts the date in the db as date - 2 hours. How do I make it convert the date correctly? I want my class to be locale-independent, always using GMT timezone. Actually, the question is: class MyOleDateTime extends Date { static { Locale.setDefault(WhatGoesHere?) } // ... some constructors // ... some methods }

• groovy call private method in Java super class

  - by Jeff Storey

  I have an abstract Java class MyAbstractClass with a private method. There is a concrete implementation MyConcreteClass. public class MyAbstractClass { private void somePrivateMethod(); } public class MyConcreteClass extends MyAbstractClass { // implementation details } In my groovy test class I have class MyAbstractClassTest { void myTestMethod() { MyAbstractClass mac = new MyConcreteClass() mac.somePrivateMethod() } } I get an error that there is no such method signature for somePrivateMethod. I know groovy can call private methods but I'm guessing the problem is that the private method is in the super class, not MyConcreteClass. Is there a way to invoke a private method in the super class like this (other than using something like PrivateAccessor)? thanks Jeff

• how to deal a constructor with an array in Perl

  - by superstar

  whats the difference between these two 'new' constructors in perl? 1) sub new { my $class = shift; my $self = {}; $self->{firstName} = undef; $self->{lastName} = undef; $self->{PEERS} = []; bless ($self, $class); return $self; } 2) sub new { my $class = shift; my $self = { _firstName => shift, _lastName => shift, _ssn => shift, }; bless $self, $class; return $self; } I am using the 2nd one so far, but i need to implement the arrays in perl? can you suggest a way to do it with the 2nd 'new' constructor and how can we use get and set methods on those array variables?

• How to get window opened/closed/minimized messages from a native app?

  - by Josh Santangelo

  It's tough to write a good title for this one. I'm working on a WPF application which needs to know about the existence of all other open windows on the system. I'm able to do this by calling the native EnumWindows method just fine, and I can call other native methods to filter out just the windows I'm interested in. This works well. The problem I'm having is that I want to know when a window is opened or closed (and, ideally, minimized). I can do this by polling with EnumWindows, but I'm finding that to be pretty slow, even if I push it off to another thread. Is there a better way to get notifications of window opened/closed/minimized? Keep in mind that my knowledge of non-managed code is pretty limited.

• Creating a QLineEdit search field for items displayed in a QListView

  - by krunk

  I want to create a search field that filters the items shown in a QListView. Basically the user could type in "foo" and only items with "foo" in the DisplayRole are shown. I already have a few ideas on how to do this, but thought I'd ask those more experienced than I. My idea would be to use some signals and slots to set a filter in the QAbstractItem model and trigger an update() in the QListView. Are there any helper methods in QListView for filtering I may have missed? Is there a canonical way of handling this I haven't run across?

• Using the Module Pattern for larger projects

  - by Rob

  I'm interested in using the Module Pattern to better organize my future projects. Unfortunately, there are only a few brief tutorials and proof-of-concept examples of the Module Pattern. Using the module pattern, I would like to organize projects into this sort of structure: project.arm.object.method(); Where "project" is my global project name, "arm" is a sub-section or branch of the project, "object" is an individual object, and so on to the methods and properties. However, I'm not sure how I should be declaring and organizing multiple "arms" and "objects" under "project". var project = window.project || {}; project.arm = project.arm || {}; project.arm.object = (function() { var privateVar = "Private contents."; function privateMethod() { alert(privateVar); } return { method: privateMethod }; }()); Are there any best practices or conventions when defining a complex module structure? Should I just declare a new arm/object underneath the last?

• Chain LINQ IQueryable, and end with Stored Procedure

  - by Alex

  I'm chaining search criteria in my application through IQueryable extension methods, e.g.: public static IQueryable<Fish> AtAge (this IQueryable<Fish> fish, Int32 age) { return fish.Where(f => f.Age == age); } However, I also have a full text search stored procedure: CREATE PROCEDURE [dbo].[Fishes_FullTextSearch] @searchtext nvarchar(4000), @limitcount int AS SELECT Fishes.* FROM Fishes INNER JOIN CONTAINSTABLE(Fishes, *, @searchtext, @limitcount) AS KEY_TBL ON Fishes.Id = KEY_TBL.[KEY] ORDER BY KEY_TBL.[Rank] The stored procedure obviously doesn't return IQueryable, however, is it possible to somehow limit the result set for the stored procedure using IQueryable's? I'm envisioning something like .AtAge(5).AboveWeight(100).Fishes_FulltextSearch("abc"). In this case, the fulltext search should execute on a smaller subset of my Fishes table (narrowed by Age and Weight). Is something like this possible? Sample code?

• bidirectional habtm linking

  - by Alexey Poimtsev

  Hi, all. I have application with 2 groups of models - content based (news, questions) and "something" based (devices, applications etc). I need to link all models between groups - for example question may belongs to 3 different things - one application and 2 devices. The same - for news. From other side - i need to see all news articles and questions related to some application or device. Any idea how to develop this in rails? I have only one idea - mixins that will add methods content_id and thing_id to models and join table.

• What are the ways to do synchronized streaming video and text?

  - by Marc

  I would like to have two streams. One being traditional streaming video and another being text. I will also build an interface that allows the user to create the text portion while watching the video. The context of these videos are usually that of an individual being filmed doing a presentation and later the next day for example, a coach will make text annotations (structured data is a plus) with the result being the text stream. It seems this is possible with Silverlight (see the article in the latest MSDN). However, what other methods are there if any? If there any, please give the reasons for why you are recommending them. Thanks. Also, I would prefer something that inst a software as a service hosted solution, but, dont let that keep you from giving an answer. Also keep in mind, the user shouldn't have to do any re-encoding of the video source, the text stream should be separate with someway to synchronize a coach's comments to an arbitrary time stamp in the video.

• Sorting array containing strings in objective c

  - by jakob

  Hello experts! I have an array named 'names' with strings looking like this: ["name_23_something", "name_25_something", "name_2_something"]; Now I would like to sort this array in ascending order so it looks like this: ["name_25_something", "name_23_something", "name_2_something"]; I guess that should start of with extracting the numbers since I want that the sorting is done by them: for(NSString *name in arr) { NSArray *nameSegments = [name componentsSeparatedByString:@"_"]; NSLog("number: %@", (NSString*)[nameSegments objectAtIndex:1]); } I'm thinking of creating a dictionary with the keys but I'm not sure if that is the correct objective-c way, maybe there some some methods I could use instead? Could you please me with some tips or example code how this sorting should be done in a proper way. Thank you

• Is it possible to build a JPA entity by extending a POJO?

  - by Freiheit

  Lets say I have the following POJO: public class MyThing { private int myNumber; private String myData; //assume getter/setter methods } Is it now possible to extend this POJO as a JPA entity? @Entity @Table(name = "my_thing") public class MyThingEntity extends MyThing implements Serializable { @Column(name = "my_number") //????????? @Column(name = "my_data") //???????? } I want to keep the POJO separate from the JPA entity. The POJO lives in a different project and is often used without a persistence layer, my project wants to persist it in a database and do so without the overhead of mapping from a POJO to an entity and back. I understand that JPA entities are POJOs, but in order to use it I would have to include a library that implements javax.persistence and the other projects using the same base object have no use for a persistence layer. Is this possible? Is this a good idea?

• Naming a typedef for a boost::shared_ptr<const Foo>

  - by Blair Zajac

  Silly question, but say you have class Foo: class Foo { public: typedef boost::shared_ptr<Foo> RcPtr; void non_const_method() {} void const_method() const {} }; Having a const Foo::RcPtr doesn't prevent non-const methods from being invoked on the class, the following will compile: #include <boost/shared_ptr.hpp> int main() { const Foo::RcPtr const_foo_ptr(new Foo); const_foo_ptr->non_const_method(); const_foo_ptr->const_method(); return 0; } But naming a typedef ConstRcPtr implies, to me, that the typedef would be typedef const boost::shared_ptr<Foo> ConstRcPtr; which is not what I'm interested in. An odder name, but maybe more accurate, is RcPtrConst: typedef boost::shared_ptr<const Foo> RcPtrConst; However, Googling for RcPtrConst gets zero hits, so people don't use this as a typedef name :) Does anyone have any other suggestions?

• DWR and Jquery into spring MVC 2.5

  - by Mark Estrada

  Hi, From my shallow reading, Spring MVC does not support jquery directly. It does enable integration with DWR framework. From my understanding of DWR, it is an ajax framework that allows you to call javas methods from javascript. Can I use both in my application? With Jquery handling most of the javascript code and client side interaction and DWR making the ajax calls? I am leaning towards learning jquery but there is no out of the box support for it in spring 2.5.

• how to bind the click event of a button and the selecteditemchanged of a listbox to a viewmodel in m

  - by Michel

  Hi, i'm just starting with the mvvm model in Silverlight. In step 1 i got a listbox bound to my viewmodel, but now i want to propagate a click in a button and a selecteditemchanged of the listbox back to the viewmodel. I guess i have to bind the click event of the button and the selecteditemchanged of the listbox to 2 methods in my viewmodel somehow? For the selecteditemchanged of the listbox i think there must also be a 'return call' possible when the viewmodel tries to set the selecteditem to another value? i come from a asp.net (mvc) background, but can't figure out how to do it in silverlight.

• Choosing routing.yml based on user culture?

  - by Erland Wiencke

  In my Symfony application I would like to choose the routing.yml based on the current user's culture; 'en' => routing.en.yml 'no' => routing.no.yml and so forth. Any suggestion to how this can be done? Edit: I am not trying to do i18n this way - I use Symfony's built-in methods for that. I simply want "static" urls to reflect the user's language: /en/projects/internal/project-name /no/prosjekter/interne/prosjektnavn /fr/baguette/champs-elysee/foux-de-fafa Where "projects" is a module, the category "internal" and "project-name" are stored in the database.

• how to disable web page cache throughout the servlets

  - by Kurt

  To no-cache web page, in the java controller servlet, I did somthing like this in a method: public ModelAndView home(HttpServletRequest request, HttpServletResponse response) throws Exception { ModelAndView mav = new ModelAndView(ViewConstants.MV_MAIN_HOME); mav.addObject("testing", "Test this string"); mav.addObject(request); response.setHeader("Cache-Control", "no-cache, no-store"); response.setHeader("Pragma", "no-cache"); response.setDateHeader("Expires", 0); return mav; } But this only works for a particular response object. I have many similar methods in a servlet. And I have many servlets too. If I want to disable cache throughout the application, what should I do? (I do not want to add above code for every single response object) Thanks in advance.
