    - by pask
    Hi all, My NSXMLParser breaks on this string: <title>AAA &#8211; BCDEFGQWERTYUIO</title> I parsed it in this way, hope is the right way: - (void) parser: (NSXMLParser *) parser foundCharacters: (NSString *) string{ [...] if ([currentElement isEqualToString:@"title"]) { if (![string isEqualToString:@""]) { [title addObject:string]; NSLog(@"str: %@", string); } } it returns me: str: AAA str: - str: BCDEFGQWERTYUIO But i want to return a single string: str: AAA - BCDEFGQWERTYUIO because it's the correct title. Any idea? Thanks.

  • How Can I switch the session storage according to the client on Ruby on Rails 2.3.5

    - by mojalin
    Hi! I have a question about sessions on ruby-on-rails. We have a several options about session storage such as cookie, active_record_store, etc.. I primarily use the cookie storage, but, there are some client which doesn't support cookie function. In that case, I have to make that client to use the "active_record_store". My rails version is 2.3.5. I found out that even though I use the active_record_store, the cookie is still available. In my situation, both session storage might be available. So, I want to make the framework to primarily use the cookie, when the cookie is available. On the other hand, the client doesn't support the cookie, secondly to use the active_record_store. I think this function requires some override to the framework, but I don't know how to do it. Do you have any idea for that? Thank you very much in advance.

  • Wordpress podcasting with youtube video hosting

    - by Salim Fadhley
    I'm trying to build a site based on Wordpress for a client. Eventually it will be used to publish videos which could be hosted locally, but to reduce costs it would be nicer if we could host all our videos on somewhere like YouTube or Vimeo. I'm looking for a plugin or a way of hacking an existing plugin in order to achieve this. The idea is that when we list a new item on the site, users of iTunes / iPod and any other (more) standards compliant podcatcher should be able to view the video. Ideally I'd like to get away without writing a single line of code, but that may not be possible. The best solution for me is the one which requires the least amount of work!

  • How to order the items in a nested LINQ-provided collection

    - by Carson McComas
    I've got a (SQL Server) database table called Category. And another database table called SubCategory. SubCategory has a foreign key relationship to Category. Because of this, thanks to LINQ, each Cateogory has a property called SubCategories and LINQ is nice enough to return all the SubCategories associated with my Category when I grab it. If I want to sort the Categories alphabetically, I can just do: return db.Categories.OrderBy(c => c.Name); However, I have no idea how to order the SubCategories collection inside each Category. My goal is to return a collection of Categories, where all of the SubCategory collections inside of them are ordered alphabetically by Name.

  • Find point which sum of distances to set of other points is minimal

    - by Pawel Markowski
    I have one set (X) of points (not very big let's say 1-20 points) and the second (Y), much larger set of points. I need to choose some point from Y which sum of distances to all points from X is minimal. I came up with an idea that I would treat X as a vertices of a polygon and find centroid of this polygon, and then I will choose a point from Y nearest to the centroid. But I'm not sure whether centroid minimizes sum of its distances to the vertices of polygon, so I'm not sure whether this is a good way? Is there any algorithm for solving this problem? Points are defined by geographical coordinates.

  • Android: making a custom ListView independent of adapters ?

    - by wei
    I am adding a local database as a cache to a remote web service in my android application to answer queries. I used ArrayAdapters before for list views to display the results from the web service. Now with a database cache, the result could be either a Cursor(from database) or a List(from web), which means the adapter can be CursorAdapter or ArrayAdapter too. Creating two adapters for one query doesn't seem to be a good idea. So I am wondering what would be the best way to refactor my current code to add this database feature? Thanks,

  • Storm Trident 'average aggregator

    - by E Shindler
    I am a newbie to Trident and I'm looking to create an 'Average' aggregator similar to 'Sum(), but for 'Average'.The following does not work: public class Average implements CombinerAggregator<Long>.......{ public Long init(TridentTuple tuple) { (Long)tuple.getValue(0); } public Long Combine(long val1,long val2){ return val1+val2/2; } public Long zero(){ return 0L; } } It may not be exactly syntactically correct, but that's the idea. Please help if you can. Given 2 tuples with values [2,4,1] and [2,2,5] and fields 'a','b' and 'c' and doing an average on field 'b' should return '3'. I'm not entirely sure how init() and zero() work. Thank you so much for your help in advance. Eli

  • Background-image toggle using jquery

    - by Jon
    Hi all, bit of a jquery rookie here trying to get something to work. Basically I have a div with a class "nav" and inside that div is a nav list. I want to change the background-image of "nav" when hovering over an item in the navlist, so I made this unsuccesful effort: enter code here $(function(){ $("li#hover-first").mouseover(function(){ $("div.nav").removeClass("nav").addClass("navbg"); .mouseout(function(){$("div.nav").removeClass("navbg").addClass("nav"); }); So the idea is, once the first li item is hovered over, the div with classname "nav" has it's class removed and has "navbg" added (which has the alternate background image). Obviously this isn't working, so any help would be greatly appreciated...thanks.

  • Dynamically set generic type argument

    - by fearofawhackplanet
    Following on from my question here, I'm trying to create a generic value equality comparer. I've never played with reflection before so not sure if I'm on the right track, but anyway I've got this idea so far: bool ContainSameValues<T>(T t1, T t2) { if (t1 is ValueType || t1 is string) { return t1.Equals(t2); } else { IEnumerable<PropertyInfo> properties = t1.GetType().GetProperties().Where(p => p.CanRead); foreach (var property in properties) { var p1 = property.GetValue(t1, null); var p2 = property.GetValue(t2, null); if( !ContainSameValues<p1.GetType()>(p1, p2) ) return false; } } return true; } This doesn't compile because I can't work out how to set the type of T in the recursive call. Is it possible to do this dynamically at all? There are a couple of related questions on here which I have read but I couldn't follow them enough to work out how they might apply in my situation.

  • Compressing as GZip WCF requests (SOAP and REST)

    - by Joannes Vermorel
    I have a .NET 3.5 web app hosted on Windows Azure that exposes several WCF endpoints (both SOAP and REST). The endpoints typically receive 100x more data than they serve (lot of data is upload, much fewer is downloaded). Hence, I am willing to take advantage from HTTP GZip compression but not from the server viewpoint, but rather from the client viewpoint, sending compressed requests (returning compressed responses would be fine, but won't bring much gain anyway). Here is the little C# snippet used on the client side to activate WCF: var binding = new BasicHttpBinding(); var address = new EndpointAddress(endPoint); _factory = new ChannelFactory<IMyApi>(binding, address); _channel = _factory.CreateChannel(); Any idea how to adjust the behavior so that compressed HTTP requests can be made?

  • How to display configurable product in each color in product listing?

    - by Thomas
    I have a configurable product which is available in many different colors and sizes. I want the configurable product to appear once for every color. My idea is to assign one simple product of the configurable product in every color to the category of the configurable product. Then I want to change the listing, so that the (colored) simple product links to it's master product (the configurable one). The other way would be, to just assign the configurable product to a category and then list it multiple times with different colors. But I think this would be to complicated.

  • What is the better approach to find if a given set is a perfect subset of a set - If given subset is

    - by Microkernel
    Hi guys, What is the best approach to find if a given set(unsorted) is a perfect subset of a main set. I got to do some validation in my program where I got to compare the clients request set with the registered internal capability set. I thought of doing by having internal capability set sorted(will not change once registered) and do Binary search for each element in the client's request set. Is it the best I could get? I suspected that there might be better approach. Any idea? Regards, Microkernel

  • Masking to Transparent returns empty image

    - by Tibi
    Hi there, I'm trying to put white color in my images to transparent with the following code. Problem is that "CGImageRef maskedTransparent" is blank. I don't understand because the code I'm using is nearly a copy paste from the doc ... Any idea ? (UIImage*) maskImage:(UIImage *)image withMask:(UIImage *)maskImage { CGImageRef maskRef = maskImage.CGImage; CGImageRef mask = CGImageMaskCreate(CGImageGetWidth(maskRef), CGImageGetHeight(maskRef), CGImageGetBitsPerComponent(maskRef), CGImageGetBitsPerPixel(maskRef), CGImageGetBytesPerRow(maskRef), CGImageGetDataProvider(maskRef), NULL, false); CGImageRef masked = CGImageCreateWithMask([image CGImage], mask); //Array defining min & max RGB values to be transformed to transparent colors. float maskingMinMax[6] = {255, 255, 255, 255, 255, 255}; //masking image to remove range in maskinLinMax CGImageRef maskedTransparent = CGImageCreateWithMaskingColors(masked, maskingMinMax); return [UIImage imageWithCGImage:maskedTransparent]; }

  • Selecting contents of Label Control

    - by j-t-s
    Hi All I have what I consider to be a pretty unique problem here, and no idea how to implement. From what I've seen, there is no documentation, tutorials, samples and/or articles on this. I've spent weeks researching, with nothing to show. The problem: I need the user to be able to select the contents of a Label Control at runtime, and edit it. If this can be done by extending the existing Label control, great! Or, if this requires a whole new Label Control to be created, fine. So be it. Using a TextBox is not an option I'm afraid. Any help at all is greatly appreciated! Thank you, jase

  • How to verify a digital signature with openssl

    - by Aaron Carlino
    I'm using a thirdparty credit card processing service (Paybox) that, after a successful transaction, redirects back to the website with a signature in the URL as a security measure to prevent people from manipulating data. It's supposed to prove that the request originated from this service. So my success URL looks something like this: /success.php?signature=[HUGE HASH] I have no idea where to start with verifying this signature. This service does provide a public key, and I assume I need to create a private key, but I don't know much beyond that. I'm pretty good with linux, and I know I'll have to run some openssl commands. I'm writing the verification script in PHP, which also has native openssl() functions. If anyone could please push me in the right direction with some pseudo code, or even functional code, I'd be very grateful. Thanks.

  • JQuery make an array - how/what is best

    - by russp
    I have 4 serailized arrays that I want to pass to php for processing. What is the best way to combine them into a single array example: serial_1 = $('#col1').sortable('serialize'); serial_2 = $('#col2').sortable('serialize'); serial_3 = $('#col3').sortable('serialize'); serial_4 = $('#col4').sortable('serialize');` each serialized array relates to a column/section of the page (col1,col2 etc.) What I need to do/would like to do is create a single array that puts the serialized array inside another array for a single post. example: var new_array = serilaize(col_1(serial_1),col2(serial_2),col3,(serial_3),col4(serial_4)) I KNOW THAT IS NOT RIGHT as I have no idea in JQuery how to right the correct syntax. This new array is to be posted via ajax like this: $.ajax({ url: "test.php", type: "post", data: new_array, error: function(){ alert('SOME ERROR MESSAGE'); } }); Thanks in advance

  • Tripple-wrapping fails: \colorbox ? \NewEnviron ? \newenvironment fails

    - by o_O Tync
    Hello! I am trying to wrap an environment created with \NewEnviron (package 'environ') into an old good \newenvironment: \NewEnviron{test}{\colorbox[gray]{0.7}{\BODY}} \newenvironment{wrapper}{\begin{test}}{\end{test}} \begin{wrapper} debug me \end{wrapper} However, this gives me a strange error: LaTeX Error: \begin{test} on input line 15 ended by \end{wrapper}. LaTeX Error: \begin{wrapper} on input line 15 ended by \end{document}. If I replace \NewEnviron{test}{aaa(\BODY)bbb} with \newenvironment{test}{aaa(}{)bbb} — everything works as expected! It seems like \NewEnviron fails to find its end for some reason. I'm trying to do some magic with 'floatfig' wrapped into a \colorbox so I need a way to convert \colorbox to an environment and wrap it into another one. I can define a new command but it's not a very good idea. Thanks in advance!

  • Asp.Net : IHttpModule + m_context.Server.Transfer = session state error

    - by tinky05
    I have an IHttpModule that implements IRequiresSessionState. The session state is at "on" on the page directive and I also added it to the web.config. In the method "OnBeginRequest" in the IHttpModule, I make a Server.Transfer but I get the error : Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. When I access the page directly or with a Response.Redirect, there is no error. Any idea? Update : The error occur in a page extending System.Web.UI.Page in the method InitializeCulture() which is an override.

    - by Malcolm
    Hi I have the following markup .NET 1.1 app. I want the grid lines of the table to be darkgray this is the goal here. <asp:table id="tbl" Runat="server" CellSpacing="0" BorderColor="darkgray" GridLines="Both"></asp:table> I have the app in IIS set as ver 1.1 in my dev box and 2.0 in production for various reasons. The page source in 1.1 renders this <table id="ctlTimesheetMonthly_tbl" cellspacing="0" rules="all" bordercolor="DarkGray" border="1" style="border-color:DarkGray;border-collapse:collapse;">` 2.0 renders this <table id="ctlTimesheetMonthly_tbl" cellspacing="0" rules="all" border="1" style="border-color:DarkGray;border-collapse:collapse;"> Which is wrong as it produces a white border for some reason. Any idea how to get both the same?? Malcolm

  • What is the best algorithm to locate a point in an image file?

    - by suugaku
    Hi all, I want to create a mark sheet recognizer. Here is the description: My system uses black and white color scheme. The mark sheet paper has a small black rectangle on each corner and an additional small black rectangle, to determine orientation, near one of the previous rectangles. The paper is scanned to yield an image (in bmp format for example). The first step is to locate these five references in image as eficient as possible. My rough idea is to trace row by row and from left to right for each row. It sounds very slow I think. Is there any better way to do that? Thank you in advance. regards, Suugaku

  • Best approach for a scalable PHP (AJAX based) chat system

    - by Simon
    Hi, I'm building a chat system for a company and I'm wondering as to what the best way to build the system would be? The current setup we have is a Nginx HTTP Server with PHP and Memcacheq (as a message queue that appends the chat messages to the user's own queue). We then poll the Nginx server (through a Comet style request) and query the message queue for updates. Is it a good idea to use a message queue such as Memcacheq to handle a chat system that has both user-to-user and site-wide chat or is it best to just stick to MySQL? Thanks!

  • Django "Error: cannot import name escape" on windows

    - by Sam
    I cannot run the dev server because of this error ("Error: cannot import name escape"). I assume its because of modifications I've done to the project, but i have no idea how to find where the error is originating from to fix it. I don't import anything called escape anywhere. Update Using django-admin.py rather than the projects manage.py, don't know why... Update 2 Now manage.py is working. This may be because I had a file called email.py which was trying to import email.mime.text (ie trying to import itself) renaming to sendemail.py solved this problem.
