• Full-Text Search in SQL Server Express Won't Recognize Latest IFilters

  - by Brandon King

  I'm having difficulty getting full-text search working in SQL Server 2008 Express with Advanced Services. I have a table loaded with .DOCX files as varbinary(MAX) data that I want to use for a full-text catalog, but it doesn't seem to recognize the .DOCX format. Here are the steps that I've taken... Installed the latest Filter Pack 2.0 Exec sp_fulltext_service 'load_os_resources', 1 Exec sys.sp_help_fulltext_system_components 'all' (NOTE: .DOCX is not shown as a filter) Building the full-text catalog fails to identify any key words I initially thought there might be a conflict between x86 SQL Express and x64 Filter Pack on my Windows 7 machine, but I just tried it with everything x86 in a Windows XP virtual machine and got the same result.

• Setting the Cursor Position in a Win32 Console Application

  - by Jim Fell

  How can I set the cursor position in a Win32 Console application? Preferably, I would like to avoid making a handle and using the Windows Console Functions. (I spent all morning running down that dark alley; it creates more problems than it solves.) I seem to recall doing this relatively simply when I was in college using stdio, but I can't find any examples of how to do it now. Any thoughts or suggestions would be greatly appreciated. Thanks.

• Is there a language designed for code golf?

  - by J S

  I am not really a fan of code golf, but I have to wonder, is there an esoteric language designed for it? I mean a language with following properties: Common programs may be expressed in very short amount of characters It uses ASCII character set effectively (for example, common operators are not identifiers, so they don't have to be separated by whitespace, character usage is distributed more or less evenly because we cannot use Huffman coding and so on) Except the terse syntax, it should have very expressible and clean semantics (like, let's say, Python or Scheme); it shouldn't be difficult to program in It doesn't need features for large scale programs, such as OOP, but it definitely should allow custom functions and data structures It should have a large standard library, identifiers in this library should be as short as possible Maybe it should be called CG? Languages that can be a source of inspiration are Forth, APL and Joy.

• C++ visitor pattern handling templated string types?

  - by Steve the Plant

  I'm trying to use the visitor pattern to serialize the contents of objects. However one snag I'm hitting is when I'm visiting strings. My strings are of a templated type, similar to STL's basic_string. So something like: basic_string<char_type, memory_allocator, other_possible_stuff> \\ many variations possible! Since I can have very many different templated string types, I can't go and add them to my visitor interface. It would be ridiculous. But I can't add templates to my VisitString method because C++ prevents using templates parameters in virtual methods. So what are my options to work around this?

• What are Class methods in Python for?

  - by Dave Webb

  I'm teaching myself Python and my most recent lesson was that Python is not Java, and so I've just spent a while turning all my Class methods into functions. I now realise that I don't need to use Class methods for what I would done with static methods in Java, but now I'm not sure when I would use them. All the advice I can find about Python Class methods is along the lines of newbies like me should steer clear of them, and the standard documentation is at its most opaque when discussing them. Does anyone have a good example of using a Class method in Python or at least can someone tell me when Class methods can be sensibly used?

• Getters and Setters: Code smell, Necessary Evil, or Can't Live Without Them [closed]

  - by Avery Payne

  Possible Duplicate: Allen Holub wrote “You should never use get/set functions”, is he correct? Is there a good, no, a very good reason, to go through all the trouble of using getters and setters for object-oriented languages? What's wrong with just using a direct reference to a property or method? Is there some kind of "semantical coverup" that people don't want to talk about in polite company? Was I just too tired and fell asleep when someone walked out and said "Thou Shalt Write Copious Amounts of Code to Obtain Getters and Setters"? Follow-up after a year: It seems to be a common occurrence with Java, less so with Python. I'm beginning to wonder if this is more of a cultural phenomena (related to the limitations of the language) rather than "sage advice". The -1 question score is complete for-the-lulz as far as I am concerned. It's interesting that there are specific questions that are downvoted, not because they are "bad questions", but rather, because they hit someone's raw nerve.

• Is it possible to register a user and submit a comment with one form with Wordpress?

  - by zack

  Is it possible to do both registering for an account and submit a comment at the same time? I want the user to be able to do this all on one page to ecourage the registration rather than be discouraged about typing something, not realizing they had to be registered and thus having to leave the page. I think that this could be done by adding register user action to the submit comment action, but not sure how to do it with the prebuilt wordpress add_action or do_action functions. Has anyone tried this, or know of any plug-ins that do this already? I searched but couldn't find anything helpful. Thanks.

• How can I upload a file to a Sharepoint Document Library using Silverlight and client web-services?

  - by pclem12

  Most of the solutions I've come across for Sharepoint doc library uploads use the HTTP "PUT" method, but I'm having trouble finding a way to do this in Silverlight because it has restrictions on the HTTP Methods. I visited this http://msdn.microsoft.com/en-us/library/dd920295(VS.95).aspx to see how to allow PUT in my code, but I can't find how that helps you use an HTTP "PUT". I am using client web-services, so that limits some of the Sharepoint functions available. That leaves me with these questions: Can I do an http PUT in Silverlight? If I can't or there is another better way to upload a file, what is it? Thanks

• Is it bad practice to use python's getattr extensively?

  - by Wilduck

  I'm creating a shell-like environment. My original method of handleing user input was to use a dictionary mapping commands (strings) to methods of various classes, making use of the fact that functions are first class objects in python. For flexibility's sake (mostly for parsing commands), I'm thinking of changing my setup such that I'm using getattr(command), to grab the method I need and then passing arguments to it at the end of my parser. Another advantage of this approach is not having to update my (currently statically implemented) command dictionary every time I add a new method/command. My question is, will I be taking a hit to the efficiency of my shell? Does it matter how many methods/commands I have? I'm currently looking at 30 some commands, which could eventually double.

• Switching Javascript Function states

  - by webzide

  Dear experts, I would like to implement a API of Javascript that sort of resemble a light switch. For instance, there are two buttons on the actual HTML page act as the UI. Both of the buttons have event handlers that invokes a different function. Each function have codes that act like a state, for instance. button1.onclick=function (){ $("div").click( //code effects 2 ) } button2.onclick=function (){ $("div").click( //Code effects 2 ) } I the code works fine on the surface but the 2 state functions overlap. the effects is going to take place for the rest of the way until the next reload of the document. Basically what I want to achieve is that when 1 button is clicked, it will switch "OFF" the state of function invoked by the other button and vice versa. Thus, the effects achieved are unique are not overlapped. Is there anyway to achieve this or could any experts point me to the right direction. Thanks in advance.

• The whole site is blocked while one page is waiting for blocking operation (PHP, ASP.NET). Why?

  - by artvolk

  Good day! I've found interesting behaviour for both LAMP stack and ASP.NET. The scenario: There is page performing task in 2-3 minutes (making HttpWebRequest for ASP.NET and curl for PHP). While this page is processed all other requests to this virtual host from the same browser are not processed (even if I use different browsers from one machine). I use two pages written in PHP and C#. I've tested with Apache+PHP in both mod_php and fast_cgi modes on Windows and Debian. For ASP.NET I use IIS6 (with dedicated app pool for this site and with default app pool) and IIS7 in integrated mode. I know that it is better to use async calls for such things, but I'm just curious why single page blocks the entire site and not only the thread processing the request? Thanks in advance!

• Webservice and ORM Framework?

  - by Sebastian

  Does anybody know a good web framework that includes an ORM mapper and allows straight forward implementation of web services? I'm looking for a framework written in PHP or C++. I'm looking for the following features (not all of them required, some will do nicely) data definition in one place used by database and web service WSDL generation XML output/JSON output boilerplate code generation So what I would like is a framework that let's me specify the objects, the web service functions on those objects and then generate everything that is required leaving me to fill the business logic (connecting the database to the web service). Anything like that out there? Background information for why I need this: I'm looking into creating a web project: the client is a rich web application that fetches all its data using AJAX. It will be completely custom made using only a low level javascript library. The server back end is supposed to serve static content and javascript (basically the rich web application) and to provide a RESTful web service API (which I would like to implement using aforementioned framework).

• car and cdr in Scheme are driving me crazy ...

  - by kristian Roger

  Hi Im facing a problem with the car and cdr functions for example: first I defined a list called it x (define x (a (bc) d ( (ef) g ) )) so x now is equal to (a (bc) d ( (ef) g ) ) now for example I need to get the g from this list using only car and cdr (!! noshortcuts as caddr cddr !!) the correct answer is: (car(cdr(car(cdr(cdr(cdr x)))))) BUT how ? :-( I work according to the rules (the car gives the head of list and cdr gives the tail) and instead of getting the answer above I keep reaching wrong answers. Can any one help me in understanding this ... give me step or a way to solve it step by step Thanks in advance. I'm really sick of Scheme.

• orbean forms bulder + custom persistance api: Why does it call /crud/.../data/data.xml?

  - by yankee

  I am currently implementing my own persistence layer for orbeon forms. As far as I have understood the virtual hierachy of data, creating a form with form builder in the application "myapp" with the name "myform" should cause the form builder to call /crud/myapp/myform/form/form.xhtml, passing the newly created form as HTTP-PUT data. Thus I created a spring method annotated with: @RequestMapping(method = RequestMethod.PUT, value = "/crud/{applicationName}/{formName}/form/form.xhtml") public void saveForm(@PathVariable String formName, @RequestBody String putData) I expected this method to be called with my form. But this method does not get called. Instead the method @RequestMapping(method = RequestMethod.PUT, value = "/crud/{applicationName}/{formName}/data/{uuid}/data.xml") public void saveInstance(@PathVariable String uuid, @RequestBody String putData) gets called. Put data contains the full xhtml form. Why is this happening? I thought that the second URL would only be called for saving an instance, more specifically the <xforms:instance id="fr-form-instance"> part of a form, once I fill in values for a form.

• Running GUI application in the Windows service mode

  - by Leonid

  I'm writing a server running as a Windows service that by request invokes Firefox to generate a pdf snapshot of a webpage. I know it is a bad idea to run a GUI program in service mode, but the server nature of my program restricts from running it in the user mode. Running a user-level 'proxy' also is not an option, since there might be no interactive user logged-in on the machine with the server running. In my experiments Firefox successfully produced pdf when the service was running under a user account that was already logged-in. Obviously it didn't work in other cases: for Local System and user accounts that weren't logged-in. Under LocalSystem with 'Allow service to interact with desktop' option enabled I could see the Firefox started that reports that it's unable to find a printer. Since it wouldn't be practical to require an opened user session for the pdf server to run, is there any workaround for this except running the whole thing from a virtual machine?

• Group MySQL Data into Arbitrarily Sized Time Buckets

  - by Eric J.

  How do I count the number of records in a MySQL table based on a timestamp column per unit of time where the unit of time is arbitrary? Specifically, I want to count how many record's timestamps fell into 15 minute buckets during a given interval. I understand how to do this in buckets of 1 second, 1 minute, 1 hour, 1 day etc. using MySQL date functions, e.g. SELECT YEAR(datefield) Y, MONTH(datefield) M, DAY(datefield) D, COUNT(*) Cnt FROM mytable GROUP BY YEAR(datefield), MONTH(datefield), DAY(datefield) but how can I group by 15 minute buckets?

• Dealing with passwords securely

  - by Krt_Malta

  Hi I have a Java web service and a Java web client making use of this service. One of the functions is to create a new user account. My two concerns are: How will I send the user's password securely from the client. How will I store the user's password securely on the server. How can I achieve these? I know the theory basically behind security, security algorithms etc but can anyone give me some advice on how I should go about in coding? Could anyone point me to some good (and if possible not complicated) examples to follow since I found some examples on the Internet very contorted? Thanks a lot and regards, Krt_Malta

• Sort NSFetchedResultsController results by user location

  - by cgp

  I have an application that contains some Locations in Core Data, and I want to show them to the user in order of proximity to the user's location. I am using an NSFetchedResultsController to serve the locations to the Table View. I thought about creating a virtual accessor method that returns the location's distance from the user, that would be calculated using a "global" CoreLocationManager, but it crashes with reason: Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'keypath distanceFromCurrentLocation not found in entity < NSSQLEntity Location id=4' I also give the user the option to sort alphabetically, so I would prefer it if I kept the NSFetchedResultsController, if possible. How should I do it? Thanks!

• Facebook javascript in address bar, possible to replicate?

  - by DoMx

  This is my first experience with stackoverflow and I'm afraid my question asks of a lot for a first. I was looking at this thread: http://stackoverflow.com/questions/2634159/javascrypt-in-the-adress-bar-is-this-malicious and as you will see SLaks has very kindly deobfuscated the javascript and left us with what appears as the Javascript behind the automatic facebook invite code. As I'm fairly new to javascript, I was wondering, what other components were needed to get this code to work? You of course have the functions there and they are called by the obfuscated javascript but how exactly? Would it be possible to replicate this on a page of my own using the information available or is there more to this script I am missing? I am willing to financially assist somebody who could compile a solution for me. Thank you in advance.

• django getting current user id

  - by dana

  hello, i have a mini app where users can login, view their profile, and follow each other. 'Follow' is a relation like a regular 'friend' relationship in virtual communities, but it is not necessarily reciprocal, meaning that one can follow a user, without the need that the user to be following back that person who follows him. my problem is: if i am a logged in user, and i navigate to a profile X, and push the button follow, how can i take the current profile id ?(current profile meaning the profile that I, the logged in user, am viewing right now.) the view: def follow(request): if request.method == 'POST': form = FollowForm(request.POST) if form.is_valid(): new_obj = form.save(commit=False) new_obj.initiated_by = request.user u = User.objects. what here? new_obj.follow = u new_obj.save() return HttpResponseRedirect('.') else: form = FollowForm() return render_to_response('followme/follow.html', { 'form': form, }, context_instance=RequestContext(request)) thanks in advance!

• What is the most useful R trick?

  - by Dirk Eddelbuettel

  In order to share some more tips and tricks for R, what is you single-most useful feature or trick? Clever vectorization? Data input/output? Visualization and graphics? Statistical analysis? Special functions? The interactive environment itself? One item per post, and we will see if we get a winner by means of votes. [Edit 25-Aug 2008]: So after one week, it seems that the simple str() won the poll. As I like to recommend that one myself, it is an easy answer to accept.

• Why does my program occasionally segfault when out of memory rather than throwing std::bad_alloc?

  - by Bradford Larsen

  I have a program that implements several heuristic search algorithms and several domains, designed to experimentally evaluate the various algorithms. The program is written in C++, built using the GNU toolchain, and run on a 64-bit Ubuntu system. When I run my experiments, I use bash's ulimit command to limit the amount of virtual memory the process can use, so that my test system does not start swapping. Certain algorithm/test instance combinations hit the memory limit I have defined. Most of the time, the program throws an std::bad_alloc exception, which is printed by the default handler, at which point the program terminates. Occasionally, rather than this happening, the program simply segfaults. Why does my program occasionally segfault when out of memory, rather than reporting an unhandled std::bad_alloc and terminating?

• is PHP itself transforming into a framework?

  - by Elzo Valugi

  At the beginning PHP was a scripting language. But after the introduction and improvement of OOP I see more and more objects added to the core. They started with SPL which grew a lot, now we have DOMDocument family, DateTime family which should be part of PECL, Pear or Zend Framework or implemented by each one of us. Shouldn't be php only for build-in functions and all these objects passed to something else? Example. DateTime class is part of the core and I see it very similar with Zend_Date.

• Registering a delegate function with an ISO C++ callback (on mono)

  - by Stick it to THE MAN

  I am thinking of wrapping ISO C++ code in C# class. The only problem so far is how to deal with the C++ callbacks. In .Net languages (C# and Vb.Net), I believe the callback equivalent. Sticking with C# for now, can anyone recommend a way that I can register the C# delegate functions with my ISO C++ code. The ISO C++ code is a notification library, and I want to be able to "push" the notifications to the mono framework (i.e. C# delegates in this case). My underlying assumption is that the mechanism/steps to implement this would be the same for the .Net languages - I'll just have to code the actual delegates in the .Net language of choice - is that assumption correct? Last but not the least, is the question of thread saftey. The underlying ISO C++ code that I am exposing to .Net (mono to be more specific), is both re-ntrant and thread safe - do I have to do anything "extra" to call .Net delegate from my ISO C++ code?

• GridView items are displaying the wrong drawables sometimes.

  - by originalbryan

  I've implemented a GridView based on this tutorial. It works great unless open up the search dialog or rotate the screen then scroll around. When the search dialog and virtual keyboard appear, the drawables for each of my grid items shift. I can click on them and they do what I expect, except the drawable is wrong. The same problem happens when I go into landscape mode and scroll around. If I scroll down, up, the down again, the drawables are shuffled. For better illustration, let's say I have three objects, each with an image. Obj A shows an Apple Obj B shows a Banana Obj C shows a Cantaloupe When the shift occurs I end up with: Obj A shows an Cantaloupe Obj B shows a Banana Obj C shows a Apple The problem isn't consistent between the two causes (search dialog and screen rotate n' scroll), but each cause itself is consistent. Scrolling around repeatedly reveals a pattern as does the search dialog appearing. How can I stop this from happening?
