• How to configure SQLite db in Visual Studio

  - by ChrisC

  I've messed with Access a little bit in the past, had one class on OO theory, and one class on console c++ apps. Now, as a hobby project, I'm undertaking to write an actual app, which will be a database app using System.Data.SQLite and C#. I have the db's table structure planned. I have System.Data.SQLite installed and connected to VS Pro. I entered my tables and columns in VS, but that's where I'm stuck. I really don't know how to finish the db set up so I can start creating queries and testing the db structure. Can someone give me guidance to online resources that will help me learn how to get the db properly set up so I can proceed with testing it? I'm hoping for online resources specific to beginners using C# and System.Data.SQLite, but I'll use the closest I can get. Thanks.

• RSS parsing last build Date. Fastest way to do so please.

  - by Paul

  Dim myRequest As System.Net.WebRequest = System.Net.WebRequest.Create(url) Dim myResponse As System.Net.WebResponse = myRequest.GetResponse() Dim rssStream As System.IO.Stream = myResponse.GetResponseStream() Dim rssDoc As New System.Xml.XmlDocument() Try rssDoc.Load(rssStream) Catch nosupport As NotSupportedException Throw nosupport End Try Dim rssItems As System.Xml.XmlNodeList = rssDoc.SelectNodes("rss/channel") 'For i As Integer = 0 To rssItems.Count - 1 Dim rssDetail As System.Xml.XmlNode rssDetail = rssItems.Item(0).SelectSingleNode("lastBuildDate") Folks this is what I'm using to parse an RSS feed for the last updated time. Is there a quicker way? Speed seems to be a bit slow on it as it pulls down the entire feed before parsing.

• Test Column exists, Add Column, and Update Column

  - by david.clarke

  I'm trying to write a SQL Server database update script. I want to test for the existence of a column in a table, then if it doesn't exist add the column with a default value, and finally update that column based on the current value of a different column in the same table. I want this script to be runnable multiple times, the first time updating the table and on subsequent runs the script should be ignored. My script currently looks like the following: IF NOT EXISTS(SELECT * FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = 'PurchaseOrder' AND COLUMN_NAME = 'IsDownloadable') BEGIN ALTER TABLE [dbo].[PurchaseOrder] ADD [IsDownloadable] bit NOT NULL DEFAULT 0 UPDATE [dbo].[PurchaseOrder] SET [IsDownloadable] = 1 WHERE [Ref] IS NOT NULL END SQL Server returns error "Invalid column name 'IsDownloadable'", i.e. I need to commit the DDL before I can update the column. I've tried various permutations but I'm getting nowhere fast.

• Easiest way of unit testing C code with Python

  - by Jon Mills

  I've got a pile of C code that I'd like to unit test using Python's unittest library (in Windows), but I'm trying to work out the best way of interfacing the C code so that Python can execute it (and get the results back). Does anybody have any experience in the easiest way to do it? Some ideas include: Wrapping the code as a Python C extension using the Python API Wrap the C code using SWIG Add a DLL wrapper to the C code and load it into Python using ctypes Add a small XML-RPC server to the c-code and call it using xmlrpclib (yes, I know this seems a bit far-out!) Is there a canonical way of doing this? I'm going to be doing this quite a lot, with different C modules, so I'd like to find a way which is least effort.

• What is the easiest way to get an embedded upload progress bar using Ruby/Sinatra/Haml/Passenger/ngi

  - by mmr

  I have a website where people can upload 30+mb of data in a single block, and I want to be able to show them the progress of their upload without causing the web page to become unresponsive, similar to how flash uploads work in gmail. There's this question here, but I don't know if that progress bar is embedded in the page or if it's using the browser's progress bar. I'm also a bit of a web newb, so I'm not sure if it's the 'easiest'. I asked the swfupload guys how to do this here, and the answer I got is 'this tool requires some knowledge to use it' without giving me much help in figuring out where to get started. I also asked this question on ServerFault, and got no response, so maybe that was the wrong place to ask. I'm all for learning new things and so forth, but there are a lot of potential pathways to take here. Where should I start, and what do I need to know to make everything work with sinatra, haml, ruby, passenger, and nginx? Thanks!

• OT: US Banks: Bank Routing Number and BIC/SWIFT

  - by Konerak

  I know it is a bit offtopic, but I've been having a hard time finding more information to this question, and since this site is visited by a lot of people from the United States, you guys might know/find the answer more easily. Banks in europe each have a SWIFT Number, while US Banks use Routing Numbers. This leads to following questions: Does each bank in the US also carry a BIC number? (SWIFT) Is there a 1-1 relationship between BIC and SWIFT? Is there a list of these numbers somewhere? (background information: we're adding international payments to our bookkeeping application. Users can add international suppliers, but my boss prefered not to change the current supplier table but to have the ROUTING NUMBER in another table, with as PK the BIC. I'm wondering if BIC is a valid choice, or if it should just be BANK ACCOUNT NUMBER.)

• Parse values from a text file in C

  - by Mohit Deshpande

  Say I have written to a text file in this format: key1/value1 key2/value2 akey/withavalue anotherkey/withanothervalue I have a linked list like: struct Node { char *key; char *value; struct Node *next; }; to hold the values. How would I read key1 and value1? I was thinking of putting line by line in a buffer and using strtok(buffer, '/'). Would that work? What other ways could work, maybe a bit faster or less prone to error? Please include a code sample if you can!

• Android SDK and AVD manager will not run from Eclipse after upgrade to SDK 5 and ADT 0.9.6

  - by user303944

  Using Windows 7, 64 bit system. Prior to upgrade I was able to run "Android SDK and AVD manager" from Eclipse via a tool bar icon and menu option, both of which still exist. However now nothing happens when I try to run the manager. As a result I can't start an emulator from within Eclipse. When I use Eclipse to run an Android app, the first emulator I installed is automatically started. Using Windows Explorer, I can still run the manager from the SDK directory in which the update was applied (the update didn't change the location of the SDK). If I run the manager and start multiple emulators and then Run an app from Eclipse, it sees the emulators and allows me to choose one as before. This is a satisfactory work-around, but it would be nice if the manager were fully integrated into Eclipse as it was before.

• What does msvc 6 throw when an integer divide by zero occurs?

  - by EvilTeach

  I have been doing a bit of experimenting, and have discovered that an exception is being thrown, when an integer divide by zero occurs. #include <iostream> #include <stdexcept> using namespace std; int main ( void ) { try { int x = 3; int y = 0; int z = x / y; cout << "Didn't throw or signal" << endl; } catch (std::exception &e) { cout << "Caught exception " << e.what() << endl; } return 0; } Clearly it is not throwing a std::exception. What else might it be throwing?

• How can I scrape the current webpage with php/javascript?

  - by Robert

  I have made the following webpage for generating interactive todo lists: http://robert-kent.com/todo/todo.php Basically, the user pastes a numbered todo list and each task is placed into it's own div with a unique id. Users can add notes to the tasks (done with javascript) and can click the green check when the task is done to hide it. I'd like to add an Export button which would generate a report of which tasks were completed and which were not, along with the user-entered notes. After a bit of searching I understand that what I want to do is scrape the page, but I haven't the faintest idea of the best way to do it. Many of the articles and tutorials I have found with Google involve scraping other sites and don't really explain how I could iterate over each div on the page. Full source here: http://pastebin.com/r7V3P5jK Any suggestions?

• Automating scraping of table data to XML

  - by thewinchester

  Problem I have a YQL query result that I'm trying to get converted and sort into a clean XML file. Background Being the pains that they are, information from the World Cup isn't freely available in an easy to reuse format. So, after a bit of finessing with YQL I have managed to liberate the required table rows which contain the data I'm after. The YQL query can be viewed at: http://query.yahooapis.com/v1/public/yql/ravingbeefsteak/worldcup2010groupliberator?diagnostics=true I'd like to now convert this information into XML, and being an absolute n00b I don't know where to start or what to look for. I'm also needing to do a find and replace on the data to get the URL's working as they should without manual changes, and hopefully an initial sorting of the data. If anyone can point me in the right direction of what I need to be doing to make my needs a reality it would be greatly appreciated.

• Unique issue with Rails setup

  - by Alexis Abril

  Becoming a bit of a Ruby convert, but I've run into an issue with my Rails installation. I realize, in spirit, this question may overlap with superuser.com, but am asking here due to the nature of the installation. My command: sudo gem install rails Response is: /opt/local/lib/ruby/vendor_ruby/1.8/rubygems/spec_fetcher.rb:232: warning:getc is obsolete; use STDIN.getc instead The "/opt/local" may be giving away the fact I'm using MacPorts(Mac OS 10.4). After that response, there is no new command line issued by the system, just a hang. Any insite is greatly appreciated.

• how to sort a multidemensional array by an inner key

  - by Derek Vance

  i have this enormous array that i am pulling from an API for BattleField Bad Company 2, and the soldier stats can be pulled as a multi dimensional array with an inner array for each soldier, however the API sormats it sorting the soldiers by name alphabetically, i want to sort them by rank (which is just another key within that soldiers array). ive been trying to figure this out for days, anyone have any ideas? (ie sort the array by $arr[players][][rank] here is a bit of the array Array ( [players] = Array ( [0] = Array ( [name] = bigjay517 [rank] = 29 [rank_name] = SECOND LIEUTENANT II [veteran] = 0 [score] = 979440 [level] = 169 [kills] = 4134 [deaths] = 3813 [time] = 292457.42 [elo] = 319.297 [form] = 1 [date_lastupdate] = 2010-03-30T14:06:20+02:00 [count_updates] = 13 [general] = Array ( [accuracy] = 0.332 [dogr] = 86 [dogt] = 166 [elo0] = 309.104 [elo1] = 230.849 [games] = 384 [goldedition] = 0 [losses] = 161 [sc_assault] = 146333 [sc_award] = 567190 [sc_bonus] = 35305 [sc_demo] = 96961 [sc_general] = 264700 [sc_objective] = 54740 [sc_recon] = 54202 [sc_squad] = 53210 [sc_support] = 70194 [sc_team] = 21215 [sc_vehicle] = 44560 [slevel] = 0 [spm] = 0 [spm0] = 0 [spm1] = 0 [srank] = 0 [sveteran] = 0 [teamkills] = 67 [udogt] = 0 [wins] = 223 )

• Postgresql - one database for everyone, or one-database per customer

  - by user337876

  I'm working on a web-based business application where each customer will need to have their own data (think basecamphq.com type model) For scalability and ease-of-upgrades, I'd prefer to have a single database where each customer gets a filtered version of the data. The problem is how to guarantee that they stay sandboxed to their own data. Trying to enforce it in code seems like a disaster waiting to happen. I know Oracle has a way to append a where clause to every query based on a login id, but does Postgresql have anything similar? If not, is there a different design pattern I could use (like creating a view of each table for each customer that filters)? Worse case scenario, what is the performance/memory overhead of having 1000 100M databases vs having a single 1Tb database? I will need to provide backup/restore functionality on a per-customer basis which is dead-simple on a single database but quite a bit trickier if they are sharing the database with other customers.

• Thin, Sinatra, and intercepting static file request to do CAS authentication

  - by Kenny Peng

  I'm using the casrack-the-authenticator gem for CAS authentication. My server is running Thin on top of Sinatra. I've gotten the CAS authentication bit working, but I'm not sure how to tell Rack to intercept "/index.html" requests to confirm the CAS login, and if the user is not allowed to view the page, return a HTTP 403 response instead of serving the actual page. Does anyone have experience with this? Thanks. My app: class Foo < Sinatra::Base enable :sessions set :public, "public" use CasrackTheAuthenticator::Simple, :cas_server => "https://my.cas_server.com" use CasrackTheAuthenticator::RequireCAS end My rackup file: require 'foo' use Rack::CommonLogger use Rack::Lint run Foo

• Software to simplify displaying build status on a big visible monitor for team?

  - by MikeJ

  I had a little bit of budget left at year end and I wanted to start a little skunk works project to display build status what everyone was working on (our team is aobut 10 folks all told). I am thinking to buy a 47" LCD HD TV and drive it from a small pc via a browser/.NET web application. I was going to build the software over the christmas break since we are closed for 2 weeks starting this Friday. I thought I would solicit advise/feedback on what other teams had done. a lot of the tools we use SVN, Mantis have RSS feeds that I was thinking to render. Is this the way to go ? Thanks for any feedback in advance.

• Vertical mouse scrolling wheel not working in VS 2010 Ultimate

  - by Robert

  The title says it all. I tried it with two different mice- both of which work perfectly fine in all other applications. The mouse is MS Intellimouse Optical. I even tried to speed up the vertical scroll through the mouse utility and still nothing. It barely moves the code a tiny bit and then it stops. I had no problems at all with VS 2008 which is concurrently installed in the same machine. Am I the only one having this???

• C#: How to change the region containing MDI children?

  - by Erlend D.

  When creating a MDI parent, the entire "inside" of the form is made the MDI region. If you add a menustrip to the MDI parent, the MDI region is scaled down a bit to make room for the menustrip. But if you add a panel to the top of the MDI parent, the entire inside is still the MDI region. Which means that you can move MDI children up behind the panel, and hide their title line. If you move MDI children behind a menustrip, scrollbars appear, and you can scroll higher up to access the title line. But the scrollbars doesn't appear when you are using a panel instead of a menustrip. Because the MDI region doesn't know about the panel, I suppose. How can I scale the MDI region to start below a given Y value?

• Change the null placeholder in a Cocoa binding?

  - by Monolo

  Is there a way to change (for the purpose of localization) the null placeholder in a binding in Cocoa? The bindings are set up in Interface Builder for a popup button. The two-way nature of the bindings as set up in IB is needed, so doing it programmatically is not really appealing. I am aware that the standard way of handling localizations of a nib file is by making one for each language, but since this is the only difference in the whole nib file between the language versions, it seems a bit excessive for a single string. If there is a way to modify a binding created in IB, I was thinning about doing it in the file's owner's awakeFromNib method.

• Compressing assets post-update with Subversion

  - by Oskar Krawczyk

  I'm trying to find a way to compress specific assets post-update on a Production server. So far, I can't find any way to do this that's even remotely simple. Anyone has any insights/experience in doing this? Basically, what I need to do is run a Java utility to compress CSS and JS files - the problem with JS files is that they may or might not validate (JS errors), if it doesn't validate the Java utility will throw output a message. This makes the whole idea a bit more complicated.

• How can I use a regular expression to match something in the form 'stuff=foo' 'stuff' = 'stuff' 'mor

  - by PherricOxide

  I need a regexp to match something like this, 'text' | 'text' | ... | 'text'(~text) = 'text' | 'text' | ... | 'text' I just want to divide it up into two sections, the part on the left of the equals sign and the part on the right. Any of the 'text' entries can have "=" between the ' characters though. I was thinking of trying to match an even number of 's followed by a =, but I'm not sure how to match an even number of something.. Also note I don't know how many entries on either side there could be. A couple examples, '51NL9637X33' | 'ISL6262ACRZ-T' | 'QFN'(~51NL9637X33) = '51NL9637X33' | 'ISL6262ACRZ-T' | 'INTERSIL' | 'QFN7SQ-HT1_P49' | '()' Should extract, '51NL9637X33' | 'ISL6262ACRZ-T' | 'QFN'(~51NL9637X33) and, '51NL9637X33' | 'ISL6262ACRZ-T' | 'INTERSIL' | 'QFN7SQ-HT1_P49' | '()' '227637' | 'SMTU2032_1' | 'SKT W/BAT'(~227637) = '227637' | 'SMTU2032_1' | 'RENATA' | 'SKT28_5X16_1-HT5_4_P2' | '()' :SPECIAL_A ='BAT_CR2032', PART_NUM_A='202649' Should extract, '227637' | 'SMTU2032_1' | 'SKT W/BAT'(~227637) and, '227637' | 'SMTU2032_1' | 'RENATA' | 'SKT28_5X16_1-HT5_4_P2' | '()' :SPECIAL_A ='BAT_CR2032', PART_NUM_A='202649' Also note the little tilda bit at the end of the first section is optional, so I can't just look for that.

• Hello World bootloader not working!

  - by Newbie

  Hello. I've been working through the tutorials on this webpage which progressively creates a bootloader that displays Hello World. The 2nd tutorial (where we attempt to get an "A" to be output) works perfectly, and yet the 1st tutorial doesn't work for me at all! (The BIOS completely ignores the floppy disk and boots straight into Windows). This is less of an issue, although any explanations would be appreciated. The real problem is that I can't get the 3rd tutorial to work. Instead on outputting "Hello World", I get an unusual character (and blinking cursor) in the bottom-left corner of the screen. It looks a bit like a smiley face inside a rounded rectangle. Does anyone know how to get Hello World to display as it should?

• Oracle .NET Provider DLL hell

  - by Pablo Santa Cruz

  I am currently developing on a Win7-32bits computer. Everything works fine. It's a ASP.NET application. I was able to use Microsoft's Oracle deprecated .NET provider to connect to Oracle (using 32 bit instant client) and also ODP.NET. No problems at all. Application runs fine. The problem comes when I deploy it to IIS7 on Windows 2008 Server 64bit computer. I can't get Microsoft's deprecated .NET provider or ODP.NET to work easily. Is there a straightforward way to use a 32bit based ODP.NET or Microsoft's Oracle deprecated .NET provider in Windows 2008 Server 64bits? DLL hell here! Thanks.
