  • $('<style></style>').text('css').appendTo('head') does not work in IE?

    - by powerboy
    It works fine in Firefox and Chrome, but does not work in IE8. Here is the html structure: <!DOCTYPE html> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script> <script type="text/javascript"> $(function() { // this does not work in the stupid IE $('<style type="text/css"></style>').text('body {margin: 0;}').appendTo('head'); }); </script> </head> <body> </body> </html> And what' s the alternative to do this in IE?

  • Active Merchant Paypal Recurring Pem Error Neither Pub Nor Priv Key

    - by Andy
    Hi, I am trying to use ActiveMerchant to make a Paypal Recurring transaction call. I used the patch here: http://blog.vuzit.com/2008/08/01/paypal-website-payments-pro-us-with-recurring-billing-and-activemerchant/ and I'm stuck on this here: ActiveMerchant::Billing::PaypalGateway.pem_file = File.read('paypal_cert.pem') I am fairly sure the pem file is correctly downloaded from paypal. The error I receive is: /Library/Ruby/Gems/1.8/gems/activemerchant-1.5.1/lib/active_merchant/lib/connection.rb:129:in initialize': Neither PUB key nor PRIV key:: nested asn1 error (OpenSSL::PKey::RSAError) from /Library/Ruby/Gems/1.8/gems/activemerchant-1.5.1/lib/active_merchant/lib/connection.rb:129:innew' from calling the commit method from line 49 of paypal_pro_recurring. I simply have 2 files - paypal_pro_recurring.rb from the tutorial and paypalTest.rb which I wrote and simply requires all files and calls the function. I hope the error isn't something stupid like I must require from an environment file or something. Thanks all!

  • [Programming General] Advantages of using software framework

    - by ignatius
    Hello, I was reading these days about large projects implementation in python and Flex, and very often people praise the use of framework (like Cairngorm, PureMVC or others) over traditional OOP coding. I think i dont really understand the advantage of using FW, which is the strong point over classic programming? how big should be the project in order to use FW? it is intended mainly for web-applications? or can be used for desktop apps as well? hope, all these doubts dont sound stupid to you, i am not Computer engineer, just electronic, so my knowledge of sw architecture is very limited.

  • C# UTF8 output keep encoded characters intact

    - by Stefan Pohl
    Hello, i have a very simple question I can't seem to get my head around. I have a properly encoded UTF8-String I parse into a JObject with Json.NET, fiddle around with some values and write it to the commandline, keeping the encoded characters intact. Everything works great except for the keeping the encoded characters intact part. Code: var json = "{roster: [[\"Tulg\u00f4r\", 990, 1055]]}"; var j = JObject.Parse(json); for (int i = 0; i < j["roster"].Count(); i++) { j["roster"][i][1] = ((int)j["roster"][i][1]) * 3; j["roster"][i][2] = ((int)j["roster"][i][2]) * 3; } Console.WriteLine(JsonConvert.SerializeObject(j, Formatting.None)); Actual Output: {"roster":[["Tulgôr",2970,3165]]} Desired Output: {"roster":[["Tulg\u00f4r",2970,3165]]} It seems like my phrasing in Google is inappropriate since nothing useful came up. I'm sure it's something uber-easy and i will feel pretty stupid afterwards. :)

  • Difference between implementing an interface and applying an attribute in C#

    - by RemotecUk
    This might be a stupid question but Ill ask anyway, I was reading "OOP Demystified: A Self-Teaching Guide by Jim Keogh and Mario Giannini" chapter 11 which covers interfaces. The examples in this book are C++. I noticed that C++ uses ISerializable to make a class serializable which you would implement where as in C# you just attribute the class with the [Serializable] attribute. What is the key difference here? Is it that with an interface you must provide the implementation where as if you attribute something the compiler will work out the implementation for you? I guess that with the [Serializable] attribute the .Net framework uses reflection to make the serialized object from the actual object. That said is it possible in that case to have an [Disposable] attribute or using my theory above the framework wont know how to actually dispose of an object hence you have to do it yourself? Would be grateful for a clarification. Thanks.

  • using a php variable in the WHERE clause of a mysql query

    - by user1262890
    I'm running a very simple query that I think should work. The only thing that I haven't done before is put a php variable in the WHERE clause of the query. The variable $X is a numerical value, say 100. When I run this query, I just get a value of 0 returned. Am I doing something obviously stupid? SELECT generator_64k.n FROM generator_64k WHERE generator_64k.n<= '$X' I've looked around the web and also tried this: SELECT generator_64k.n FROM generator_64k WHERE generator_64k.n<= '" . $X . "' But this also just returns 0. Any ideas? Thanks in advance.

  • Compile C# into objective-C

    - by Ali Shafai
    Now that monotouch is being banned, I was wondering if there is a way to translate C# (or some other modern language for that matter) into objective-C? I won't mind using apple's api as long as I don't have to declare my variables in 3-4 stages (ivar-property-synthesize-dealloc). All I want is a less wordy language to concentrate on my intent and not on the compiler syntax. unfortunately apple in its arrogance thinks objective-c is a "modern" language and if you are looking for an alternative (monotouch) it's because you are incapable of coding. also if you don't find programming in itunes; sorry, xcode enjoyable, it is not because there are better alternatives, it's because you are stupid. anyway back to my original question: can it be done?

  • Problem creating site using Microsoft Visual Web Developer Express 2008

    - by Peter
    Hi, this is a very newbie question, sorry! I need to create an aspx website based con C# and am calling some webservices based on some DLL's I already have. Beforem purchasing Visual Studio, I decided to try Microsoft Visual Web Developer Express (is this ok?) creating a Web Application ASP.NET based on Visual C#. I created the form to enter the data which is submitted when clicking the process button. At this point I need to call stuff from the DLL, which I have added in the Solution Explorer via Add Reference, selecting the DLL from the COM list. But whenever I run the project, I always get the error "the type or namespace xxx cannot be found - maybe a using directive or assembler directive is missing" when trying to create the object. What is my stupid mistake? Thanks!

  • Boost interprocess cached pools

    - by porgarmingduod
    I'm trying to figure out if my reading of the docs for boost interprocess allocators is correct. When using cached_adaptive_pool to allocate memory: typedef cached_adaptive_pool<int, managed_shared_memory::segment_manager> pool_allocator_t; pool_allocator_t pool_allocator(segment.get_segment_manager()); // Allocate an integer in the shared memory segment pool_allocator_t::pointer pool_allocator.allocate_one(); My understanding is that with multiple processes one can allocate and deallocate freely: That is, if I have a cached pool allocator for integers in one process, then it can deallocate integers allocated by similar pools in other processes (provided, of course, that they are working on the same shared memory segment). It may be a stupid question, but working with multiple processes and shared memory is hard enough, so I'd like to know 100% whether I got the basics right.

  • IE Specific JavaScript

    - by Banderdash
    This feels like a stupid question, or one that could be answered with a little trial and error and some Googleing--but I assure you I have tried both and several ideas and am not getting the results I'm after. Here are my JS includes for a site: <!-- JavaScript --> <script type="text/javascript" src="http://code.jquery.com/jquery-latest.min.js"></script> <script type="text/javascript" src="js/accordian.js"></script> <!--[if IE 7]><script type="text/javascript" src="js/ie-accordian.js"></script><![endif]--> I'm simply trying to deliver the ie-accordian.js to IE 7 and accordian.js to all other browsers. Just not having any luck keeping IE 7 from using accordian.js as opposed to the one created especially for it. Any thoughts?

  • iTunes Visualizer Plugin in C# - Energy Function

    - by James D
    Hi, iTunes Visualizer plugin in C#. Easiest way to compute the "energy level" for a particular sample? I looked at this writeup on beat detection over at GameDev and have had some success with it (I'm not doing beat detection per se, but it's relevant). But ultimately I'm looking for a stupid-as-possible, quick-and-dirty approach for demo purposes. For those who aren't familiar with how iTunes structures visualization data, basically you're given this: struct VisualPluginData { /* SNIP */ RenderVisualData renderData; UInt32 renderTimeStampID; UInt8 minLevel[kVisualMaxDataChannels]; // 0-128 UInt8 maxLevel[kVisualMaxDataChannels]; // 0-128 }; struct RenderVisualData { UInt8 numWaveformChannels; UInt8 waveformData[kVisualMaxDataChannels][kVisualNumWaveformEntries]; // 512-point FFT UInt8 numSpectrumChannels; UInt8 spectrumData[kVisualMaxDataChannels][kVisualNumSpectrumEntries]; }; Ideally, I'd like an approach that a beginning programmer with little to no DSP experience could grasp and improve on. Any ideas? Thanks!

  • How can I condense stand-alone characters in Perl?

    - by brydgesk
    I'm trying to identify and condense single (uppercase) characters in a string. For example: "test A B test" - "test AB test" "test A B C test" - "test ABC test" "test A B test C D E test" - "test AB test CDE test" I have it working for single occurrences (as in the first above example), but cannot figure out how to chain it for multiple occurrences. $str =~ s/ ([A-Z]) ([A-Z]) / \1\2 /g; I'll probably feel stupid when I see the solution, but I'm prepared for that. Thanks in advance.

  • NO-SQL reliable for small bussines app?

    - by mamcx
    I'm deciding between go for a NON-SQL engine or a regular SQL one for a document managment system for small bussines. I have experience with firebird/sql server and found a good track of reliability (specially with firebird). This market is full of crappy "servers" (clon-made PC, the mayority), cheap harddisk, rarely use of RAID or anything like that, some are in locations where a power-off is normal, some not have a UPS, etc... (I will include off-site auto-backup to external servers, but that no change the internal setup). (I know about end-user education about such proper setups, but is stupid depend on that, so stick to te point) From the desing point of view, a schema-less database is the way to go for my system, but, I worry if any of the actual solutions (MongoDb, Tokyo Cabinet, etc) are like firebird and survice crash, malfunctions & abuse so data corruption is very rare. The plan is store the office documents there & provide a central repository.

  • PHP and writing clean code

    - by Pirkka
    Hello Im trying to find best practices to write PHP. I just wonder is this a bad habit. For example, processing variables. $var = 1 $var = doSomething($var); $var = doSomething2($var); $var = doSomething3($var); It looks a bit awful. Here is a example of a real code that I just did: $this->rSum = explode(",", $this->options["rSum"]); $this->rSum = array_combine(array_values($this->rSum), array_fill(0, count($this->rSum), 0)); If someone could pass me some good tutorials of writing cleaner code generally it would be nice! Its me again asking stupid questions. :)

  • iPhone sdk, at dismissModalViewcontrollerAnimated, the parent change y origin coordinate

    - by DigitalVanilla
    Hi guys, my first post here :) I'm having a small trouble with a small but boring problem. I have a view, with a NavigationController. I load in the NC a simple view. Inside this view there's abutton where I fire the presentModalView... in the main view, not on NC, but it's parent view: ABVIEW NC NEWVIEW new attach a presentModalView... on ABVIEW, so [abview present...]; No problem till now. When it's the time to dismiss, after the temporary window (let's calls it NOTES) disappear, my ABVIEW with all the subviews change Y position from 0 to 20, the same height of the status bar. I was looking everywhere and I'm sure it's a stupid thing, but I miss a bit of knowledge here and I have no idea where to find the solution. thanks in advance!

  • boost pool_alloc

    - by mr grumpy
    Why is the boost::fast_pool_allocator built on top of a singleton pool, and not a separate pool per allocator instance? Or to put it another way, why only provide that, and not the option of having a pool per allocator? Would having that be a bad idea? I have a class that internally uses about 10 different boost::unordered_map types. If I'd used the std::allocator then all the memory would go back to the system when it called delete, whereas now I have to call release_memory on many different allocator types at some point. Would I be stupid to roll my own allocator that uses pool instead of singleton_pool? thanks

  • How do you handle the deletion of your model working with ViewModels and keeping them in sync ?

    - by Lisa
    Hello, these could be my entity relations: 1 Pupil has 1 Chair 1 Pupil has N Documents 1 Pupil has N Marks 1 Pupil has N IncidentReports etc... So with that sample I get 4 IEnumerable from my database put each into an ObservableCollection. Now I have 4 different Views each bound to one of those 4 collections. Lets assume I delete a single PupilViewModel in the AdministrationController which is the only View where I can delete a PupilViewModel. Now I have to inform 3 other Controller and their ObservableCollections about the one deleted PupilViewModel to keep the whole application synchronized... thats stupid somehow. Do you have any good advice on that scenario? AND it gets even worse. If I delete a schoolclass I have to sync the pupils everywhere AND the documents or incidentreports or marks... gush... o_O

  • Storing extended IIdentity in HttpContext.Current.User (IPrinciple)

    - by UpTheCreek
    I have created an ExtendedId class which extends GenericIdentity. (This stores Id as well as name) In a httpmodule I stored this extended id in Current.User like so: HttpContext.Current.User = new GenericPrincipal(myExtendedId, roles); Problem is, later, how do I get at my ExtendedId type again? If I try this: ExtendedId eId = (ExtendedId)HttpContext.Current.User.Identity; I get a casting error. I have a feeling I'm doing something stupid here with casting, but I'm a bit foggy this morning.

  • How to run a PowerShell script?

    - by Pekka
    Guys and Gals, a really stupid question: How do I run a PowerShell script? I have a script named myscript.ps1 I have all the necessary frameworks installed I set that execution policy thing I have followed the instructions on this MSDN help page and am trying to run it like so: powershell.exe 'C:\my_path\yada_yada\run_import_script.ps1' (with or withot --noexit) which returns exactly nothing, except that the file name is output. No error, no message, nothing. Oh, when I add -noexit, the same thing happens but I remain within Powershell, and have to exit manually. The ps1 file is supposed to run a program, and return the error level dependant on that program's output. But I'm quite sure I'm not even getting there yet. What am I doing wrong?

  • PHP array : simple question about multidimensional array

    - by Tristan
    Hello, i've got a SQL query which returns multiple rows, and i have : $data = array( "nom" => $row['nom'] , "prix" => $row['rapport'], "average" => "$moyenne_ge" ); which is perfect, but only if my query returns one row. i tried that : $data = array(); $data[$row['nom']]["nom"] = $row['nom'] ; ... $data[$row['nom']]['average'] = "$moyenne_ge"; in order to have : $data[brand1][nom] = brand1 $data[brand1][average] = 150$ $data[brand2][nom] = brand2 $data[brand2][average] = 20$ ... but when i do : json_encode($data) i only have the latest JSON object instead of all JSON object from my request as if my array has only one brand instead of 10. I guess i did something stupid somewhere. Thanks for your help

  • Can Core Data be used on Linux?

    - by glenc
    This might be a stupid question, but I was wondering whether or not you can use the Core Data libraries on Linux at all? I'm planning how to build the server side of an iPhone app that I'm working on, and have found that you can use PyObjC to get access to Core Data in a Python environment, e.g. use Core Data in a TurboGears web application. At this point I'm thinking that you would have to run the web server on Mac OSX, because I can't find any evidence on the internet that you can access the Objective-C libraries on Linux. I've always written webapps on Linux but will obviously make the jump to an OSX server if it allows me to use the same datastore implementation on the iPhone and the server, the only job remaining being the Core Data <- Web Services XML translation that has to happen on the wire.

  • Ruby on Rails Foreigner plugin not working for SQL Server

    - by Earlz
    Well, now that I've finally got my stupid ODBC stuff configured, I took a schema.rb file that I dumped from a Postgres database and did a db:schema:load on it in a Rails project configured for SQL Server. Well, it sets up all the schema in the SQL Server database except for a minor detail: No foreign keys are created. The rake command doesn't show any errors and does say it is adding foreign keys. But they don't actually get added. This is the last bit from the command: -- add_foreign_key("workhistoryform", "form", {:name=>"workhistoryform_form_rid_fkey", :column=>"form_rid", :primary_key=>"form_rid"}) -> 0.0002s -- initialize_schema_migrations_table() -> 0.0092s -- assume_migrated_upto_version(0) -> 0.0942s [earlz@earlzarch avp_msql_migrations]$ So what is the problem? Does the Foreigner plugin not work in SQL Server? If it didn't I'd expect to see an error or something...

  • OpenGLES mix and match blending options complicated question

    - by DevDevDev
    So I have a background line drawing, black and white. I want to be able to draw over this, keeping the black lines in there, and drawing only where it is white. I can do this by using glBlendFunc(GL_DST_COLOR, GL_ONE_MINUS_SRC_ALPHA); And the black stays black and white gets whatever color I want. However in the white areas, I want to be able to draw some color, pick to another color and then blend. However this doesn't work because the blend function is messed up. So what I was thinking is having a linedrawing framebuffer, and a user-drawing framebuffer. The user draws into the userdrawing framebuffer, with a different blending, and then I switch blending options and draw into the linedrawing framebuffer. But i don't know enough OpenGL to say whether or not this will work or is a stupid idea. Thanks a lot

  • WSDL: What do I do with it? Add service Reference? Noobie question

    - by Johnny
    Hey guys! I have been given a WSDL with all the method requests and responses, and all the objects I'll need to use for creating a few webmethods. The thing is, I don't know what to do with it. I've added the WSDL as a Service Reference. I can see the methods and structures, I can instantiate them, it's all there, but the project doesn't build as soon as I add the WSDL. "Error 2 The type name 'ServiceReference1' does not exist in the type 'WSPELab.WSPELab' C:\Users\JJ\Documents\Visual Studio 2008\Projects\WSPELab\WSPELab\Service References\ServiceReference1\Reference.cs 21 111 WSPELabSLN Is it a stupid namespace error on my part? EDIT : Forgot to add this. With the WSDL added, can I used the structures it contains directly? Or are they just "listings" for me to implement? Thanks!
