• floats in NSArray

  - by JordanC

  I have an NSArray of floats which I did by encapsulating the floats using [NSNumber numberWithFloat:myFloat] ; Then I passed that array somewhere else and I need to pull those floats out of the array and perform basic arithmatic. When I try [myArray objectAtIndex:i] ; The compiler complains that I'm trying to perform arithmatic on a type id. It also won't let me cast to float or double. Any ideas? This seems like it should be an easy problem. Maybe it will come to me after another cup of coffee, but some help would be appreciated. Thanks.

• getting error 500 with .htaccess when pointing an existing file / folder (mod_rewrite)

  - by Leto

  i made a simple .htaccess file to expose the problem. I want that all request made to the folder redirect to a subfolder file "app/index.php" RewriteEngine On RewriteRule (.*) app/index.php [QSA] And this works fine on with the basic url of my hoster (like http//myname.hosting.com/htaccessFolder The problem is that i have a domain pointing on this folder, and when accessed to it, server return Internal Server Error 500. If i do this : RewriteEngine On RewriteRule (.*) somefile.php [QSA] Redirection works only when file does not exists (404 not found error occured). when the file exists i get a 500 error too. I've asked the hosting support without success for the moment..

• How do you extract data from a Date/Time widget from a C++ MFC dialog in VS2008

  - by jkerian

  This is a fairly basic question, but I haven't been able to find any from-to guides from VS6-VS2008. I have a dialog box that contains controls of various types, I've discovered the way of auto-generating OnBnClickedMyFooBarButtonHere() methods via the Properties dialog on the dialog editor. I can also use CWnd::GetDlgItemText(int ,CString &) to extract text, and the oddly paramaterized GetDlgItemInt(int, bool*, bool) to extract signed integers, but is there really no other option for a Date or Time value other than Manually adding in all the DDX_ crap that the class wizard used to do in VS6 Using GetDlgItemText and then parsing whatever it gives me?

• How to prompt for username and password entry in C# / SQL ASP.NET web app?

  - by salvationishere

  How do I prompt for username and password in my C#/SQL web application? This was developed in VS 2008 on a 32-bit XP. The current connection string I'm using in my web.config file is: <add name="AdventureWorksConnectionString2" connectionString="Data Source=SIDEKICK;Initial Catalog=AdventureWorks;Persist Security Info=false; " providerName="System.Data.SqlClient" /> When I select Basic Authentication it pops up the warning: "The authentication option you have chosen results in passwords being sent over the network without data encryption..." How do I choose this authentication method and still send passwords over securely? So essentially I am looking for the most secure authentication method but that still requires users to input password?

• What is the best way to log errors in Zend Framework in my project at this stage?

  - by Pasta

  We built an app in Zend Framework and have not worked a lot in setting up error reporting and logging. Is there any way we could get some level or error reporting without too much change in the code? Is there a ErrorHandler plugin available? The basic requirement is to log errors that happens within the controller, missing controllers, malformed URLs, etc. I also want to be able to log errors within my controllers. Will using error controller here, help me identify and log errors within my controllers? How best to do this with minimal changes?

• Can you use POST to run a query in Solr (/select)

  - by RyanFetz

  I have queries that I am running against out solr index that sometimes have very long query parameters, I get errors when i run these queries, which i assume are do to the limit of a GET query parameters. Here is the method I use to query (JSON), this is to show I am using the Http Extensions (the client i use is a thin wrapper for HttpClient) not an end to end solution. 90% of the queries run fine, it is just when the params are large i get the 500 error from solr. I have read somewhere you can use POSt's when doing the select command but have not found examples of how to do it. Any help would be fantastic! public string GetJson(HttpQueryString qs) { using (var client = new DAC.US.Web.XmlHttpServiceClient(this.Uri)) { client.Client.DefaultHeaders.Authorization = new Microsoft.Http.Headers.Credential("Basic", DAC.US.Encryption.Hash.WebServiceCredintials); qs.Add("wt", "json"); if (!String.IsNullOrEmpty(this.Version)) qs.Add("version", this.Version); using (var response = client.Get(new Uri(@"select/", UriKind.Relative), qs)) { return response.Content.ReadAsString(); } } }

• List filtering: list comprehension vs. lambda + filter

  - by Agos

  I happened to find myself having a basic filtering need: I have a list and I have to filter it by an attribute of the items. My code looked like this: list = [i for i in list if i.attribute == value] But then i thought, wouldn't it be better to write it like this? filter(lambda x: x.attribute == value, list) It's more readable, and if needed for performance the lambda could be taken out to gain something. Question is: are there any caveats in using the second way? Any performance difference? Am I missing the Pythonic Way™ entirely and should do it in yet another way (such as using itemgetter instead of the lambda)? Thanks in advance

• ASP.MVC ModelBinding Behaviour

  - by OldBoy

  This one has me stumped, despite the numerous posts on here. The scenario is a basic MVC(2) web application with simple CRUD operations. Whenever the edit form is submitted and the UpdateModel() called, an exception is thrown: System.Data.Linq.ForeignKeyReferenceAlreadyHasValueException was unhandled by user code This occurs against a DropDownList value which is a foreign key on the entity table. However, there is another DropDownList list on the form, representing another foreign key, which does not throw the error (unsurprisingly). Changing the property values manually inside the Edit Action: Recipe recipe = repository.GetRecipe(int.Parse(formValues["recipeid"])); recipe.CategoryId = Convert.ToInt32(formValues["CategoryId"].ToString()); recipe.Page = int.Parse(formValues["Page"].ToString()); recipe.PublicationId=Convert.ToInt32(formValues["PublicationId"].ToString()); Allows the CategoryId and Page properties to be updated, and then the error is thrown on the PublicationId. All of the referential integrity is checked an the same in the db and the dbml. Any light shed on this would be most welcome.

• PHP File Upload + jQuery

  - by st4ck0v3rfl0w

  Hello Everyone, So I have my upload script working just fine, but now it's a matter of making it look the way I want for my layout. <input type="file" name="userfile" id="userfile"/> This obviously shows a textbox with a Choose File button. What I really need is my own custom button (which will ultimately be an image) that upon successful file select (not upload quite yet) triggers a jQuery event to show a div. I do NOT want the filename textbox to show. Basic steps outlined below. User clicks on image button to upload their file User selects file jQuery shows a div with more fields User clicks submit and file is uploaded

• opengl es transparent fog in android

  - by Sponge

  I was wondering why the fog i use in opengl es on my android phone isn't transparent when i set the colors alpha to 0. I set the background to transparent and it works fine and the Color class or the toFloatBuffer() method are working fine for my meshes but when i set the fog color to transparent then this fact is ignored. here is the basic code i use for fog in the onSurfaceCreated() method of my renderer: gl.glFogf(GL10.GL_FOG_MODE, GL10.GL_LINEAR); gl.glFogf(GL10.GL_FOG_START, 4.0f); gl.glFogf(GL10.GL_FOG_END, 10.0f); gl.glFogfv(GL10.GL_FOG_COLOR, new Color(0,0,0,0).toFloatBuffer()); gl.glEnable(GL10.GL_FOG);

• Adding a Jar to ext and using it in Eclipse

  - by Bob Breznak

  I am providing a client with a lab station image for a school program. There is a library that I'd like to directly add to the JRE so that students can use the library without needing to fiddle with adding the classpath. As this is a basic after school program, the goal is to just get students into programming with as little overhead additions as possible. At this point, I have the lib put into the jre/lib/ext and Eclipse is able to find it, however it will not allow access to any of the classes. I see it in the JRE System Library and the classes and packages are showing up there but when I go to use it, I am getting an "Access restriction" error. When I remove the JRE System Library then add it back in, everything works swimmingly. The library is accessible exactly as intended. Any ideas on how to resolve this?

• Problem installing wordpress child themes.

  - by Jay

  Hi, I've tried to install either the Fusion or Thematic child themes for my blog. My Wordpress directory is located at myblog/wordpress while my domain is just myblog (example). Everything works fine with both basic themes or the parent Fusion or Thematic themes. When I install a child theme for either framework, I can view the preview and select 'activate.' However, after that my entire site crashes. I can't even view the wordpress admin panel. I've had to restore my database from my hosting provider just to get my blog working. All that I'm able to see is my favicon icon and a blank page. I've tried to deactivate all plugins and this doesn't help either. I really want to use the Hybrid News child template. Any thoughts on what might be happening? thanks so much!

• Data Validation for Random varying Phone Numbers

  - by baron

  I am storing phone numbers of varying lengths in my WPF (C#, VS 08) App. I store them as strings. My question is about my method AddNewPhoneNo(string phoneNo). In this method, I use Int.TryParse to validate the incoming number (i.e. not null, is numeric...). I've since realized this is probably not the best way to do this, because then I am limited to a number which is ± 2147483647. Definetly this is not always the case with phone numbers. What is a good, easy way to validate phone numbers? I guess the basic rules would be as follows: All numeric All positive Upto 25 chars (could be more, but this will to do for time being) Can't thing if theres any more rules at the moment, that's probably it.

• What is a good way of coding a file processing program, which accepts multisource data in Java

  - by jjepsuomi

  I'm making a data prosessing system, which currently is using csv-data as input and output form. In the future I might want to add support for example database-, xml-, etc. typed input and output forms. How should I desing my program so that it would be easy to add support for new type of data sources? Should simply make for example an abstract data class (which would contain the basic file prosessing methods) and then inherit this class for database, xml, etc. cases? Hope my question is clear =) In other words my question is: "How to desing a file prosessing system, which can be easily updated to accept input data from different sources (database, XML, Excel, etc.)".

• Allow a new line anywhere in the regex?

  - by Scott Chamberlain

  I am having a find a replace in a bunch of RTF documents, The basic pattern I need is \{(?:\\\*)?\\field\\fldlock\{\\\*\\fldinst ?MERGEFIELD ?((?:\\.*?)?[\w\[\]]+?)(?:\\.*?)?\}(?:\{\\fldrslt\})?\} However I then found out there could potentialy be a newline before each slash, so it turned in to this. \{(?:\s*\\\*)?\s*\\field\s*\\fldlock\s*\{\s*\\\*\s*\\fldinst\s*MERGEFIELD\s*((?:\\.*?)?[\w\[\]]+?(?:\s*\\.*?)?)?\s*\}(?:\s*\{\s*\\fldrslt\s*\})?\s*\} But then I hit this it fails fees totaling $\protect {\field\fldlock{\*\fldinst MERGEFIELD ENTEROUTSTANDINGVETERINARYF EES}}\plain\f0\fs24\prot Is there way have to have it match a new line anywhere in the search too without adding (?:\r?\n)? everywhere? EDIT To clear up confusion on the new lines. I need to keep the newlines in the document, I only want to remove the newlines if they are inside my match, so in the final example I posted it should replace fees totaling $\protect {\field\fldlock{\*\fldinst MERGEFIELD ENTEROUTSTANDINGVETERINARYF EES}}\plain\f0\fs24\prot with fees totaling $\protect ENTEROUTSTANDINGVETERINARYFEES\plain\f0\fs24\prot

• How to launch an external application on BN_CLICKED?

  - by Alienexist

  I'm fairly new to Windows programming. I'm doing a simple launcher app for WinCE using VC++ (not MFC). So far I've created the basic interface and buttons and stuff. I just wanted to know the best way to launch an external application when the user clicks the button (on BN_CLICKED). I found some methods such as ShellExecute, CreateProcess and others. But I couldn't get it to work (yet?). Any suitable reference or simple example on this?

• Web Designer looking to learn back-end programming...

  - by Tabetha Moe

  Hello, my name is Tabetha and I have a question... I am a web designer, but I always find that while designing the layout and coding the design I come up with great ideas for websites. I would like to know where I need to start in order to learn back-end programming not only for the knowledge, but also for the challenge of it. I have searched online but can't seem to find the information I am looking for. If anyone can give me a simple, straight-forward "this is what language you need to learn" answer, or perhaps guide me in the right direction I would appreciate it ten-fold. I am a complete noob when it comes to this, so even the most basic information is probably a pearl of wisdom for me. :)

• Should I still use querystrings for page number, etc, when using ASP.NET 4 URL Routing?

  - by Scott

  I am switching from Intelligencia's UrlRewriter to the new web forms routing in ASP.NET 4.0. I have it working great for basic pages, however, in my e-commerce site, when browsing category pages, I previously used querystrings that were built into my pager control to control paging. An old url (with UrlRewriting) would be: http://www.mysite.com/Category/Arts-and-Crafts_17 I now have a MapPageRoute defined in global.asax as: routes.MapPageRoute("category-browse", "Category/{name}_{id}", ~/CategoryPage.aspx"); This works great. Now, somebody clicks to go to page 2. Previously I would have just tacked on ?page=2 as the querystring. Now, How do I handle this using web forms routing? I know I can do something like: http://www.mysite.com/Category/Arts-and-Crafts_17/page/2 But in addition to page, I can have filters, age ranges, gender, etc. Should I just keep defining routes that handle these variables, or should I continue using querystrings and can I define a route that allows me to use my querstrings like before?

• Whats the best to way convert a set of Java objects to another set of objects?

  - by HDave

  Basic Java question here from a real newbie. I have a set of Java objects (of class "MyClass") that implement a certain interface (Interface "MyIfc"). I have a set of these objects stored in a private variable in my class that is declared as follows: protected Set<MyClass> stuff = new HashSet<MyClass>(); I need to provide a public method that returns this set as a collection of objects of type "MyIfc". public Collection<MyIfc> getMyStuff() {...} How do I do the conversion? The following line gives me an error that it can't do the conversion. I would have guessed the compiler knew that objects of class MyClass implemented MyIfc and therefore would have handled it. Collection<MyIfc> newstuff = stuff; Any enlightenment is appreciated.

• I need a simple slideshow for images of different sizes

  - by Darryl Young

  I'm looking for a very basic slideshow which displays images of various sizes. For example, the first image could be a standard 800x600 but the next might be a taller portrait image and so on. The slideshow doesn't need to have any controls. The specification just states that the page will be black and in the centre there'll be the area where images will display. As far as I know, it will be very simple like this - www.jeffcutter.net. I'm limited on time here so I'm not able to look into writing a custom one or anything like that. I just need to get some images displaying like in the example. Thanks in advance, it's much appreciated. Have a great weekend! Regards.

• How do I use Ajax and Jquery to get an array from PHP and post it?

  - by Jared

  Hello, I am using a separate PHP file as a configuration file for everything else on a basic ecommerce site. $product1["short"] = "product one"; $product1["menuimgslideshowsrc"] = "image/product1.jpg"; When I hover over a button, I want to get $product1["menuimgslideshowsrc"] and swap it out with an IMG SRC. I can do the swapping no problem, I need to know how to get the information stored in $product1["menuimgslideshowsrc"]. I assume I would use Ajax, but I am open to other ideas. Thanks in advance.

• How do you keep Cocoa controllers from getting too big?

  - by zoul

  Hello! Do you have some tricks or techniques to break Cocoa controller classes into smaller chunks? I find that whatever I do the controllers end up being one of the more complicated classes in my design. The basic stuff is simple, but once I have several pop-overs or action sheets running, things get uncomfortably complex. It's not that bad, but still I would like to refactor the code into several standalone chunks. I thought about categories, but the code is not that independent (a lot of times it needs to tap into viewWillAppear, for example) and I find that I spend a long time fighting the compiler. I also thought about adding functionality in layers using inheritance, but that feels like a hack.

• Is it possible to run node script from a web page as differnt user?

  - by Blame

  I'am searching for days now but could not get an answer. I would like to do the following: User connects to editor.html (Apache2 with basic http auth) User want to open a file on the server with his user/pass (same as in passwd) Node.js Script gets startet with user rights from above and user can edit file The Node Script will handly the connection via websockets and read/writes files. I think the biggest problem is that its not possible to run a node script on the server from a web page... and I don´t want to involve any php/cgi scripts... only Apache and Node.js / JS. Please also comment or answer if you know that it is really not possible... Thanks! Kodak
