• RegEx - Take all numeric characters following a text character

  - by Simon

  Given a string in the format: XXX999999v99 (where X is any alpha character and v is any numeric character and v is a literal v character) how can I get a regex to match the numeric characters following the v? So far I've got 'v\d\d' which includes the v but ideally I'd like just the numeric part. As an aside does anyone know of a tool in which you can specify a string to match and have the regex generated? Modifying an existing regex is one thing but I find starting from scratch painful! Edit: Re-reading this question I realise it reads like a homework assignment! However I can assure you it's not, the strings I'm trying to match represent product versions appended to product codes. The current code uses all sorts of substring expressions to retrieve the version part.

• Text formatting within textarea

  - by musoNic80

  Variations on my problem have been discussed elsewhere, so I hope I'm not duplicating! I'm implementing a simple Private Messaging System as part of a web app. I've got an annoying problem though when dynamically inserting text into a textarea box in order to make a reply. Getting the content and displaying it is fine, but I can't work out how to format it correctly. Obviously, I can't use html tags, but plain text formatting like line breaks and carriage returns seem to be ignored too. This happens when an existing message is being displayed either as part of a reply or as a thread in a new message. How do I check what formatting is being saved in my db? Or indeed what formatting is being sent back from my db?!

• How do I create a new folder and deploy files to the 12 hive using VseWSS 1.3?

  - by Nathan DeWitt

  I have created a web part using VSeWSS 1.3. It creates a wsp file and my web part gets installed, everything works great. I would like to also create a folder in the LAYOUTS directory of the 12 hive and place a couple files in there. How do I go about doing this? I know that I can manually place the files there, but I would prefer to have it all done in one fell swoop when I uses stsadm to install my solution. Is there a best practices guide out there for using VSeWSS 1.3 to do this? They changed a bunch of stuff with this new version and I want to make sure I don't mess anything up.

• Compare Your Internet Cost and Speed to Global Averages [Infographic]

  - by ETC

  Internet pricing and speed varies wildly across the world. The US, for instance, currently ranks 15th in speed but enjoys reasonably priced internet access. How reasonably priced? If you’re a US citizen you likely have an average internet access speed of 4.8 mbps and you pay a little over $3 per mbps. If you’re in Sweden, however, you likely have an 18 mbps connection and you pay a scant 63 cents per mpbs. The real envy of the internet speed Olympics by far is Japan with a mighty 61 mbps at a mere 27 cents per mbps.

  - by Miau

  I have a result of a xlinq that is an enumerable with id and phones, I want to transform that to a Dictionary, that part is simple, however the part of transforming the phone numbers from a XElement to a string its proving hard xLinqQuery.ToDictionary(e => e.id, e => e.phones.ToList()); will return Dictionary<int, List<XElement>> what i want is a Dictionary<int, List<String>> I tried with e.phones.ToList().ForEach(...) some strange SelectMany, etc ot no avail Thanks

• Building iPhone static library for armv6 and armv7 that includes another static library

  - by Martijn Thé

  Hi, I have an Xcode project that has a "master" static library target, that includes/links to a bunch of other static libraries from other Xcode projects. When building the master library target for "Optimized (armv6 armv7)", an error occurs in the last phase, during the CreateUniversalBinary step. For each .o file of the libraries that is included by the master library, the following error is reported (for example, the FBConnectGlobal.o file): warning for architecture: armv6 same member name (FBConnectGlobal.o) in output file used for input files: /Developer_Beta/Builds/MTToolbox/MTToolbox.build/Debug-iphoneos/MTToolbox.build/Objects-normal/armv6/libMTToolbox.a(FBConnectGlobal.o) and: /Developer_Beta/Builds/MTToolbox/MTToolbox.build/Debug-iphoneos/MTToolbox.build/Objects-normal/armv7/libMTToolbox.a(FBConnectGlobal.o) due to use of basename, truncation and blank padding In the end, Xcode tells that the build has succeeded. However, when using the final static library in an application project, it won't build because it finds duplicate symbols in one part of build (armv6) and misses symbols in the other part of the build (armv7). Any ideas how to fix this? M

• Pylons paginator question

  - by Timmy

  Only comments associated with the current page should be listed, so once again the query is modified to include the page ID. In this case, though, we also have to pass the pageid argument, which will in turn get passed to any h.url_for() calls in the paginator. from http://pylonsbook.com/en/1.1/simplesite-tutorial-part-2.html i cannot get this to work, the paginator does not pass things to the h.url_for, i followed the tutorial. i had to add pageid to the h.url_for in list.html. how do i solve? part of the code: ${h.link_to( comment.id, h.url_for( controller=u'comment', action='view', id=unicode(comment.id) ) )} but it does not work properly until i put in ${h.link_to( comment.id, h.url_for( controller=u'comment', action='view', id=unicode(comment.id), pageid = c.page.id ) )}

• WinForms Application Hangs

  - by Ram

  Hi, I have an application (ABC) that I developed and it as a windows application (.exe). It is by itself quite a big application referring a lot of dll's. However, now there is a requirement that demands that this application(ABC) be a part of an even larger application (XYZ). Hence, I had to change the project type of "ABC" from being a windows application to a class library, and by changing a few lines of code. My problem is that, ever since I started using ABC as part of XYZ, the application started hanging if I dint perform any operation on it for 10 to 15 mins... I do not have any problems while running it as a separate application. Any reasons why this might occur? Any suggestions would be really appreciated... Thanks, Ram

• Calculating string sizes on iPhone on a background thread

  - by jbrennan

  I've got some somewhat hefty string size calculations happening in my app (each one takes close to 500ms, and happens when the user scrolls to a new "page" in my app (like the Weather app). The delay only happens once per page, as the calculation only needs to be run once (and can even be cached for subsequent launches with the same data). Anyway, I still like to not block the UI for this type of work, as to me it screams using threads, but I know UIKit is not meant to be used from other threads. (I know NSString is not part of UIKit, but the string sizing methods are part of the UIKitAdditions...) So how should I go about doing this? What's the best way to not block the UI and do so safely?

• Redirecting a HTTP rqueust and response code/headers

  - by Bill Zimmerman

  Hi, I have a loosely coupled web app (one part uses PHP, the other uses WGSI). The WSGI/python framework shares the authentication with the PHP app, meaning that generally, the user should Log in via the PHP interface Now the user can access any of the WSGI pages [this part works if the user has logged in] What I want to do though, is if a user tries to access a WSGI page while not logged in (maybe from a previous bookmark), I would like to redirect him to the login page, and after logging in redirect him back to the orignal URL. I'm not very experienced with server-side programming, so here are my questions. How should I redirect the user back to the PHP login page? What should the HTTP status code be? Do I need to set any extra header information? What is a good way/best practice method to pass the original URL to the login page, and then after logging have it redirect the user back. Thank you!

• DSP - How are frequency amplitudes modified using DFT?

  - by Trap

  I'm trying to implement a DFT-based equalizer (not FFT) for the sole purpose of learning. To check if it works I took an audio signal, analyzed it and then resynthesized it again with no modifications made to the frequency spectrum. So far so good. Now I tried to silence some frequency bands, just by setting their amplitudes to zero before resynthesis, but definitely it's not the way to go. What I get is a rather distorted signal. I'm using the so-called 'standard way of calculating the DFT' which is by correlation. I first tried to modify the real part amplitudes only, then modifying both the real and imaginary part amplitudes. I also tried to convert the DFT output to polar notation, then modifying the magnitude and convert back to rectangular notation, but none of this is working. Can someone show me what I'm doing wrong? I tried to find info on this subject in the internet but couldn't find any. Thanks in advance.

• Unit test class inherited from ContextBoundObject and decorated with ContextAttribute

  - by Joel Cunningham

  I am trying to retrofit unit tests on to some existing code base. Both the class and method I want to unit test is decorated with custom attributes that are inherited from ContextBoundObject and ContextAttribute. I dont want them to run as part of the unit test. The only solution I have come up with is to compile the attribute out when I want to unit test. I dont really like this solution and would prefer to either replace it with a mocked attribute at runtime or prevent the attribute from running in a more elegant way. How do you unit test code that has class and method attributes that inherit from ContextBoundObject and ContextAttribute that you dont want to run as part of a unit test? Thanks in advance.

• Is there a better way to convert SQL datetime from hh:mm:ss to hhmmss?

  - by Johann J.

  I have to write an SQL view that returns the time part of a datetime column as a string in the format hhmmss (apparently SAP BW doesn't understand hh:mm:ss). This code is the SAP recommended way to do this, but I think there must be a better, more elegant way to accomplish this TIME = case len(convert(varchar(2), datepart(hh, timecolumn))) when 1 then /* Hour Part of TIMES */ case convert(varchar(2), datepart(hh, timecolumn)) when '0' then '24' /* Map 00 to 24 ( TIMES ) */ else '0' + convert(varchar(1), datepart(hh, timecolumn)) end else convert(varchar(2), datepart(hh, timecolumn)) end + case len(convert(varchar(2), datepart(mi, timecolumn))) when 1 then '0' + convert(varchar(1), datepart(mi, timecolumn)) else convert(varchar(2), datepart(mi, timecolumn)) end + case len(convert(varchar(2), datepart(ss, timecolumn))) when 1 then '0' + convert(varchar(1), datepart(ss, timecolumn)) else convert(varchar(2), datepart(ss, timecolumn)) end This accomplishes the desired result, 21:10:45 is displayed as 211045. I'd love for something more compact and easily readable but so far I've come up with nothing that works.

• Teaching coworkers LINQ...

  - by cyberzed

  I have set myself upon a journey to educate my coworkers (all have accepted my mission, even the boss). Every day I seem to find a piece of code that could have been less error prone if my coworkers knew more about the framework, better-know-framework (in courtesy of DNR ;)) is part two of my teaching process. First part is teaching my coworkers about LINQ, what it can do for them and how it is written. My big question is where are all the good basic resources for LINQ education, everything if find is tightly coupled to Linq2Sql or all other sorts of material. Neither have I been able to find a tutorial for the actual linq syntax (except a specification of it all). (I hope this haven't been asked before but if it has please say so, cause then my searching skills have failed ;) )

• Decimal numbers works in iPhone simulator but NOT on iPhone device

  - by matsoftware

  Hi everybody, I noticed a weird behaviour of iPhone OS when using decimal values. The simulator parse them from strings in a correct way but when I test the app on my iPhone it lose the decimal part. In particular, I store values in a dictionary that I retrieve in this way: Code: NSString *thickStr = [dictionary valueForKey:@"thickness"]; NSNumber *thickNum = [[[self class] numberFormatter] numberFromString:thickStr]; [self setSpessore:thickNum]; where the "numberFormatter" class is defined as below: Code: + (NSNumberFormatter *)numberFormatter { static NSNumberFormatter *_formatter; if (_formatter == nil) { _formatter = [[NSNumberFormatter alloc] init]; [_formatter setNumberStyle:NSNumberFormatterDecimalStyle]; [_formatter setFormatterBehavior:NSNumberFormatterBehavior10_4]; [_formatter setGeneratesDecimalNumbers:TRUE]; } return _formatter; } But it doesn't work! The App on iPhone keeps on convert the string to a simple integer, forgetting the decimal part, while the app on iPhone simulator works fine!

• OSLO, ANTLR or other parser grammar, for parsing QUERY EXPRESSION

  - by Jay Allard

  Greetings I'm working on a project that requires me to write queries in text form, then convert them to some easily processed nodes to be processed by some abiguous repository. Of everything there, the part I'm least interested is the part that converts the text to nodes. I'm hoping it's already done somewhere. Because I'm making stuff up as I go, I chose to use a LINQish expression syntax. from m in Movie select m.A, m.B I started parsing it manually and got the basics, but it's pretty cheesy. I'm looking for the better solution. I made some progress using MGrammar, but it would be nice if such a thing already existed. Does anyone know of anything that already does this? I looked for existing ANTLR templates, but no luck. Thanks for the help.

• JQuery Passing Variable From href to load()

  - by dvancouver

  I am trying to pass an href id to load() in JQuery, I can see from the alert the returned id# 960, so I know the id value is getting past I just don't know how to append the load url, well the $("#refreshme_"+add_id) is the important part, I use that to refresh the unique div id in the page assigned by the database pull, so it would be looking for id="refreshme_960". My simple example that is obviously not working. I want to refresh the db select part of the page showing the new list of cars. Any ideas? $(document).ready(function() { $(".add_to_favorites").livequery("click", function(event) { var add_id = this.id.replace("add_", ""); //taken from a.href tag alert (id); $.get(this.href, function(data) { $("#refreshme_"+add_id).load("http://www.example.com/car_list/"+add_id); <a class="add_to_cars" href="/car-add/960/add'}" id="add_960">Add Car</a>

• Inserting Rows in Relationship using a Strongly Typed DataSet

  - by Manuel Faux

  I'm using ADO.NET with a strongly typed dataset in C# (.NET 3.5). I want to insert a new row to two tables which are related in an 1:n relation. The table Attachments holds the primary key part of the relation and the table LicenseAttachments holds the foreign key part. AttachmentsDataSet.InvoiceRow invoice; // Set to a valid row, also referenced in InvoiceAttachments AttachmentsDataSet.AttachmentsRow attachment; attachment = attachmentsDataSet.Attachments.AddAttachmentsRow("Name", "Description"); attachmentsDataSet.InvoiceAttachments.AddInvoiceAttachmentsRow(invoice, attachment); Of course when I first update the InvoicesAttachments table, I'll get a foreign key violation from the SQL server, so I tried updating the Attachments table first, which will create the rows, but will remove the attachment association in the InvoiceAttachments table. Why? How do I solve this problem?

• Splitting up a Rails/Ruby app onto multiple servers

  - by craig.kaminsky

  We recently moved a large application to two machines, both running the same codebase. I. Machine A Web server for public facing application Receives web hook call backs from our ESP Handles a few large, list-processing jobs (uploaded spreadsheets with data) II. Machine B Manages a massive set of (background) jobs but, primarily, focuses on building and assembling newsletters Runs all integration with our NetSuite platform Runs all system maintenance (read: DB) jobs To me, having these two apps running the same codebase (a large, monolithic Rails application) seems 'wrong'. I am wondering if anyone has advice on how to better break up the code for these two apps. While they both need the same DB and, ultimately, the same model code, Machine B has no need for Controllers and Views and it feels wasteful running a full-stack Rails app for its tasks. A couple things came to mind but I'm not sure if I'm trying to solve a problem that doesn't exist: Break the models out into a sub-module on git and include into both apps Build out the Mahcine B app in plain Ruby or a lighter framework like Sinatra (where I could use ActiveRecord with Sinatra in combo with a sub-module for the model folder). I'm new to this scenario and appreciate any and all feedback or direction! Thank you.

• How to generate complex url like stackoverflow?

  - by Freewind

  I'm using playframework, and I hope to generate complex urls like stackoverflow. For example, I want to generate a question's url: http://aaa.com/questions/123456/How-to-generator-a-complex-url Note the last part, it's the title of the question. But I don't know how to do it. UPDATED In the playframework, we can define routes in conf/routes file, and what I do is: GET /questions/{<\d+>id} Questions.show In this way, when we call @{Questions.show(id)} in views, it will generate: http://aaa.com/questions/123456 But how to let the generated has a title part, is difficult.

• Git on windows :|

  - by Sonic Soul

  i've been experimenting with git as my personal code rep.. and it has been a bit of a disaster with windows. i've used Subversion, CVS, and Perforce in the past.. none were as annoying to use as git. i've figured out the PGP part (for github), although my workstation no longer lets me check in, and after searching around it turns out that git bash is using putty which is not that reliable and should be configured with something else.. i was not able to configure it with windows shell extension for a nice visual of what is part of the repository, what is modified, and easy check ins, and easy pushes.. has anyone successfully configured some kind of windows shell client and can efficiently and quickly synchronize various machines? It just seems to be more pain to use than it is worth..
