• Saving a select count(*) value to an integer (SQL Server)

  - by larryq

  Hi everyone, I'm having some trouble with this statement, owing no doubt to my ignorance of what is returned from this select statement: declare @myInt as INT set @myInt = (select COUNT(*) from myTable as count) if(@myInt <> 0) begin print 'there's something in the table' end There are records in myTable, but when I run the code above the print statement is never run. Further checks show that myInt is in fact zero after the assignment above. I'm sure I'm missing something, but I assumed that a select count would return a scalar that I could use above?

• How can I use Lucene for personal name (first name, last name) search?

  - by os111

  I'm writing a search feature for a database of NFL players. The user enters a search string like "Jason Campbell" or "Campbell" or "Jason". I'm having trouble getting the appropriate results. Which Analyzer should I use when indexing? Which Query when querying? Should I distinguish between first name and last name or just index the full name string? I'd like the following behavior: Query: "Jason Campbell" - Result: exact match for 1 player, Jason Campbell Query: "Campbell" - Result: all players with Campbell in their name Query: "Jason" - Result: all players with Jason in their name Query: "Cambel" [misspelled] - Result: all players with Campbell in their name

• PHP's SimpleXML not handling &#8217 ; properly

  - by Matty

  I'm parsing an RSS feed that has an &#8217; in it. SimpleXML turns this into a ’. What can I do to stop this? Just to answer some of the questions that have come up - I'm pulling an RSS feed using CURL. If I output this directly to the browser, the &#8217; displays as ’ which is what's expected. When I create a new SimpleXMLElement using this, (e.g. $xml = new SimpleXmlElement($raw_feed); and dump the $xml variable, every instance of &#8217; is replaced with ’. It appears that SimpleXML is having trouble with UTF-8 ampersand encoded characters. (The XML declaration specifies UTF-8.) I do have control over the feed after CURL has retrieved the feed before it's used to construct a SimpleXML element.

• algorithm to combinatorics

  - by peiska

  I am trying to solve a combinatorics problem, it seems easy, but i am having some trouble with it. If i have at most X tables, and N persons to sit on the tables, Each table can have 1 to N seating places, and I can only sit persons in one side of a rectangular table( so the order how people sit matters). I want to make a code that can calculate all the distributions of seating places from 1 up to K tables. For example, if I have 12 persons and 1 table i have 479001600 ways of seating persons( thats easy to calculate I've used Factorial of 12). But if I have 12 persons and 3 tables i have 4390848000 ways of seating persons. I've tried different solutions but i was not able to find the correct one. I've tried to divided the 12 in 3, then o use factorial of the result (it didnt work), i've tried to use 12! * 3( it didn't work too). Can some one give me a tip in a algorithm that i can use?

• Strange thing about .NET 4.0 filesystem enumeratation functionality

  - by codymanix

  I just read a page of "Whats new .NET Framework 4.0". I have trouble understanding the last paragraph: To remove open handles on enumerated directories or files Create a custom method (or function in Visual Basic) to contain your enumeration code. Apply the MethodImplAttribute attribute with the NoInlining option to the new method. For example: [MethodImplAttribute(MethodImplOptions.NoInlining)] Private void Enumerate() Include the following method calls, to run after your enumeration code: * The GC.Collect() method (no parameters). * The GC.WaitForPendingFinalizers() method. Why the attribute NoInlining? What harm would inlining do here? Why call the garbage collector manually, why not making the enumerator implement IDisposable in the first place? I suspect they use FindFirstFile()/FindNextFile() API calls for the imlementation, so FindClose() has to be called in any case if the enumeration is done.

• [PyGTK] How to Create a Multiline Button

  - by EShull

  I'm trying to create a multiline button with PyGTK. I have a label added to my subclass of gtk.Button, but I'm having trouble sizing the label to the button. If the label makes it's own size, there is no text wrapping even with label.set_line_wrap(True) because the label simply resizes beyond the bounds of the button. I would set the size of the label to that of the button, but unless I explicitly set the size of the button using set_size_request, I haven't been able to find out how big the button is (it's packed in a table). Any suggestions?

• How do I properly add the Kal framework to my iPhone project?

  - by BeachRunnerJoe

  I'm new to iPhone development and I'm having trouble using the 3rd part Kal framework in my project. I can't find any documentation on how to add the Kal framework to my code, so I assumed it was just a matter of adding the source files to my project's "Groups and Files" and set the Header file search path to include the new code. Is that all I need to do to properly add the Kal framework to my iPhone project? I'm getting this error (shown below), what is it indicating? Undefined symbols: ".objc_class_name_KalViewController", referenced from: literal-pointer@__OBJC@__cls_refs@KalViewController in RootViewController.o ld: symbol(s) not found I get this error when I add the statement... kalViewController = [[[KalViewController alloc] init] autorelease]; to my RootViewController.m viewDidLoad method and #import "Kal.h" Thanks so much for your help!

• doctrine findby relation

  - by iggnition

  I'm having trouble selecting a subset of data with doctrine. I have 3 tables Location Contact Contact_location The contact and location tables hold a name and an id the other table holds only ID's. For instance: Location loc_id: 1 name: detroit Contact contact_id: 1 name: Mike Contact_location loc_id: 1 contact_id: 1 In doctrine there is a many to many relation between the location and contact tables with contact_location as the ref_class. What i want to do is on my location page i want to find all contacts where for instance the loc_id = 1. I tried: $this->installedbases = Doctrine::getTable('contact')->findByloc_id(1); hoping doctrine would see the relation and get it, but it does not. How can i make doctrine search in relevant related tables? I read it can be done using Findby but i find the documentation unclear.

• Cython - properly declaring C funs

  - by deepblue

  I'm having trouble with running a bare example. I'm using this to declare a function in Cython coming from cinterf.h header: cdef extern from 'cinterf.h': int xsb_init_string(char* p_xsb_path) The declaration in the C header file is: DllExport extern int call_conv xsb_init_string(char *); both DllExport and call_conv are macros defined elsewhere, and resolve to GCC compiler directives. do I have to use those as well inside cdef to fully match the declaration? When I call xsb_init_string() as: xsb_init_string('some string') The python interpreter gives me: 'ImportError: ./py_ext.so: undefined symbol: xsb_init_string' Am I declaring the xsb_init_string() signature properly, inside cdef?

• High volume SVM (machine learning) system

  - by flyingcrab

  I working on a possible machine learning project that would be expected to do high speed computations for machine learning using SVM (support vector machines) and possibly some ANN. I'm resonably comfortable working on matlab with these, but primarly in small datasets, just for experimentation. I'm wondering if this matlab based approach will scale? or should i be looking into something else? C++ / gpu based computing? java wrapping of the matlab code and pushing it onto app engine? Incidentally, there seems to be a lot fo literature on GPUs, but not much on how useful they are on machine learning applications using matlab, & the cheapest CUDA enlabled GPU money can buy? is it even worth the trouble?

• Unit Testing & Fake Repository implementation with cascading CRUD operations

  - by Erik Ashepa

  Hi, i'm having trouble writing integration tests which use a fake repository, For example : Suppose I have a classroom entity, which aggregates students... var classroom = new Classroom(); classroom.Students.Add(new Student("Adam")); _fakeRepository.Save(classroom); _fakeRepostiory.GetAll<Student>().Where((student) => student.Name == "Adam")); // This query will return null... When using my real implementation for repository (NHibernate based), the above code works (because the save operation would cascade to the student added at the previous line), Do you know of any fake repository implementation which support this behaviour? Ideas on how to implement one myself? Or do you have any other suggestions which could help me avoid this issue? Thanks in advance, Erik.

• Facebook Canvas Apps, New API

  - by James

  I'm having some trouble with switching to the new JS API for a number of things with creating applications within FB, specifically the "Tab". <!-- function do_perm() { Facebook.showPermissionDialog('publish_stream,email,offline_access', null); } //--> This no longer works for me when called via an onclick command. Also, with the new API and an FBML app. How does this exactly work? The documentation is really poor so I am confused when looking at the old wiki, and the new developer site. Apologies for being pretty vague, but I'm just generally confused with the lack of clear direction with the new API and help would be greatly appreciated. I'm simply just trying to create a call that prompts for the new style user permission dialog, and oncomplete calls another JS function.

• Django: reverse lookup URL of feeds?

  - by Santa

  I am having trouble doing a reverse URL lookup for Django-generated feeds. I have the following setup in urls.py: feeds = { 'latest': LatestEntries, } urlpatterns = patterns('', # ... # enable feeds (RSS) url(r'^feeds/(?P<url>.*)/$', 'django.contrib.syndication.views.feed', {'feed_dict': feeds}, name='feeds_view'), ) I have tried using the following template tag: <a href="{% url feeds_view latest %}">RSS feeds</a> But the resulting link is not what want (http://my.domain.com/feeds//). It should be http://my.domain.com/feeds/latest/. For now, I am using a hack to generate the URL for the template: <a href="http://{{ request.META.HTTP_HOST }}/feeds/latest">RSS feeds</a> But, as you can see, it clearly is not DRY. Is there something I am missing?

• Windows Service Webbrowser object invalid cast exception error

• Python - Check if numbers in list are factors of a number

  - by Zach

  Hey, I have a list of numbers (integers) (say, from 1 to 10). They're not necessarily consecutive, but they are in ascending order. I've prompted the user multiple times to enter a choice of the available numbers. When that number is entered, it is removed from the list along with any of its factors that may be there. I've prevented the user from selecting prime numbers. However, at some point in time, there may be non-prime numbers there, which have no factors remaining. I'm relatively new to Python, so I'm having trouble implementing: Checking if the number selected has no factors remaining (even if it is not prime). Checking if only prime numbers remain, or numbers without factors. I'm thinking of using for statements, but I'm not sure exactly how to implement them. Can anyone offer advice, or code? Thanks in advance... PS. In case anyone's wondering, I'm doing an implementation of the game of Taxman in Python.

• Invalid padding on ASP 2.0 cookie, MVC looks ok

  - by brian b

  We have a cookie management library that writes a cookie containing some sensitive information, encrypted with Rijndael. The cookie encrypts and decrypts fine in unit tests (using Moq), works fine for MVC web applications, but when called from an ASP.net 2.0 website, the cookie cannot be decrypted. "Padding is invalid and cannot be removed." We are sure that the cookie value is valid because we tested it 10,000 times with random data in a unit test. There is something about what ASP.NET 2.0 does when it reads and writes the cookie that causes trouble. There has to be a gotcha. Any suggestions?

• SharedPreferences.onSharedPreferenceChangeListener not being called consistently

  - by synic

  I'm registering a preference change listener like this (in the onCreate() of my main activity): SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(this); prefs.registerOnSharedPreferenceChangeListener( new SharedPreferences.OnSharedPreferenceChangeListener() { public void onSharedPreferenceChanged( SharedPreferences prefs, String key) { System.out.println(key); } }); The trouble is, the listener is not always called. It works for the first few times a preference is changed, and then it is no longer called until I uninstall and reinstall the app. No amount of restarting the application seems to fix it. I found a mailing list thread reporting the same problem, but no one really answered him. What am I doing wrong?

• Redirect console input and output to a textbox.

  - by Peter

  Hi there and thanking in advance I am trying (very hard) to redirect Console input and output into a textbox. So far output is working fine but the trouble is with input. For example I cannot execute a simple program that will do the following: Console.WriteLine("Please enter your name: "); string name = Console.ReadLine(); Console.WriteLine("Hi there " + name); The reason I can't achieve this is because that the program has to stop while waiting for user to type his/her name and press enter. If I wait for user input on a new thread then the main GUI thread freezes and the textbox can never receive the KeyPress. This thing has me totally stumped. Any advice (or better still code) would be greatly appreciated. Cheers

• Is there a solution for deploying IIS websites that's similar to Capistrano?

  - by Matt Ephraim

  Capistrano is a great solution for building scripts that automatically deploy a website and/or a database. But, it's also very *nix centric, and from I've read it would probably be more trouble than it's worth to get it working with a Windows server. Is there a similar solution that would allow me to deploy an ASP.Net website to an IIS server and a SQL Server database? What I'm looking for is something that would allow the same kind of flexibility that Capistrano allows, as far customizing how I want the site to be deployed, what version control system I want to pull from, how it will handle rollbacks to a previous version of a site, etc. So far, I haven't been able to find a free solution that has the same sort of functionality that Capistrano has.

• Isolate SQL field using regex

  - by Das123

  I'm trying to isolate a specific field in a SQL dump file so I can edit it but I'm not having any luck. The regex I'm using is: ^(?:(?:'[^\r\n']*'|[^,\r\n]*),){6}('[^\r\n']*'|[^,\r\n]*) Which is supposed to grab the seventh field and place it inside reference 1. The trouble is that this is stumbling when ever it finds a comma inside a text field and counts the partial match as the allowable matches. Eg. (1, 'Title', 1, 3, '2006-09-29', 'Commas, the bane of my regex', 'This is the target', 2, 4) matches " the bane of my regex'" instead of "'This is the target'".

• Round-robin assignment

  - by Robert

  Hi, I have a Customers table and would like to assign a Salesperson to each customer in a round-robin fashion. Customers --CustomerID --FName --SalespersonID Salesperson --SalespersonID --FName So, if I have 15 customers and 5 salespeople, I would like the end result to look something like this: CustomerID -- FName -- SalespersonID 1 -- A -- 1 2 -- B -- 2 3 -- C -- 3 4 -- D -- 4 5 -- E -- 5 6 -- F -- 1 7 -- G -- 2 8 -- H -- 3 9 -- I -- 4 10 -- J -- 5 11 -- K -- 1 12 -- L -- 2 13 -- M -- 3 14 -- N -- 4 15 -- 0 -- 5 etc... I've been playing around with this for a bit and am trying to write some SQL to update my Customers table with the appropriate SalespersonID, but am having some trouble getting it to work. Any ideas are greatly appreciated!

• Cassandra/HBase or just MySQL: Potential problems doing the next thing

  - by alexeypro

  Say I have "user". It's the key. And I need to keep "user count". I am planning to have record with key "user" and value "0" to "9999+ ;-)" (as many as I'll have). What problems I will drive in if I use Cassandra, HBase or MySQL for that? Say, I have thousand of new updates to this "user" key, where I need to increment the value. Am I in trouble? Locked for writes? Any other way of doing that? Why this is done -- there will be a lot of "user"-like keys. Different other cases. But the idea is the same. Why keep it this way -- because I'll have more reads, so I can always get "counted value" very fast.
