  • ASP.net AppendHeader not working in ASP MVC

    - by Chao
    I'm having problems getting AppendHeader to work properly if I am also using an authorize filter. I'm using an actionfilter for my AJAX actions that applies Expires, Last-Modified, Cache-Control and Pragma (though while testing I have tried including it in the action method itself with no change in results). If I don't have an authorize filter the headers work fine. Once I add the filter the headers I tried to add get stripped. The headers I want to add Response.AppendHeader("Expires", "Sun, 19 Nov 1978 05:00:00 GMT"); Response.AppendHeader("Last-Modified", String.Format("{0:r}", DateTime.Now)); Response.AppendHeader("Cache-Control", "no-store, no-cache, must-revalidate"); Response.AppendHeader("Cache-Control", "post-check=0, pre-check=0"); Response.AppendHeader("Pragma", "no-cache"); An example of the headers from a correct page: Server ASP.NET Development Server/9.0.0.0 Date Mon, 14 Jun 2010 17:22:24 GMT X-AspNet-Version 2.0.50727 X-AspNetMvc-Version 2.0 Pragma no-cache Expires Sun, 19 Nov 1978 05:00:00 GMT Last-Modified Mon, 14 Jun 2010 18:22:24 GMT Cache-Control no-store, no-cache, must-revalidate, post-check=0, pre-check=0 Content-Type text/html; charset=utf-8 Content-Length 352 Connection Close And from an incorrect page: Server ASP.NET Development Server/9.0.0.0 Date Mon, 14 Jun 2010 17:27:34 GMT X-AspNet-Version 2.0.50727 X-AspNetMvc-Version 2.0 Pragma no-cache, no-cache Cache-Control private, s-maxage=0 Content-Type text/html; charset=utf-8 Content-Length 4937 Connection Close

  • Image animation over CGContextDrawPDFPage

    - by BittenApple
    I'm modifying the QuartzDemo sample app from Apple. In QuartzViewController.m I have modifications (by DyingCactus) which replac the back button and add a method to handle the back button press as follows: -(void)viewDidLoad { // Add the QuartzView [scrollView addSubview:self.quartzView]; //add custom back button if this is the PDF view... if ([self.quartzView isKindOfClass:[QuartzPDFView class]]) { self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"QuartzDemo" style:UIBarButtonItemStyleBordered target:self action:@selector(myBackButtonHandler:)]; } } - (void)myBackButtonHandler:(id)sender { [self.quartzView setFrame:CGRectMake(150, -200, 100, 200)]; [UIView beginAnimations:nil context:nil]; [UIView setAnimationDelegate:self]; [UIView setAnimationDidStopSelector:@selector(animationDidStop:finished:context:)]; [UIView setAnimationDuration:1.0]; [self.quartzView setFrame:CGRectMake(150, 0, 100, 200)]; [UIView commitAnimations]; } - (void)animationDidStop:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context { [self.navigationController popViewControllerAnimated:YES]; } I have a PNG image in resources folder called "bookmark.png" and would like to have that image animate as in animation in the example above. The image can be loaded in an UImageview or something and lets say that I have one called bookmark. How do I call that instead of self.quartzview in this part of code: [self.quartzView setFrame:CGRectMake(150, -200, 100, 200)]; [UIView beginAnimations:nil context:nil]; [UIView setAnimationDelegate:self]; [UIView setAnimationDidStopSelector:@selector(animationDidStop:finished:context:)]; [UIView setAnimationDuration:1.0]; [self.quartzView setFrame:CGRectMake(150, 0, 100, 200)]; [UIView commitAnimations];

  • How to Sort ip addresses and merge two files in efficent manner using perl or *nix commands?

  • Semantic Grid System, Media Query issue

    - by Andy
    I'm using the Semantic Grid System to build a responsive site. However, something isn't quite right with the media queries that should obviously kick in once it hits a particular screen size. I'll reference what i mean with their example on the website : if I view this on my iPhone for example, given that it is supposed to adjust to a single column structure on a mobile device, it still throws out the web version of the page. That is true for both Safari and Chrome on my iPhone. However, if I use the RWD bookmarklet to check it's appearance at different resolutions it appears as expected for the mobile resolution. Also, ironically, if I resize the page in Safari on my desktop it also adjusts accordingly once I get down to the approriate screen size, but not in Firefox. The media query that it uses once it hits 720px is @media screen and (max-width: 720px) { #maincolumn, #sidebar { .column(12); margin-bottom: 1em; } } and I might be wide of the mark here but I think that must be the issue. But given that this is directly from the semantic.gs website I'm not inclined to question their own code. Any idea what the problem might be?

  • Update existing Preference-item in a PreferenceActivity upon returning from a (sub)PreferenceScreen

    - by aioobe
    I have a PreferenceActivity with a bunch of (Sub)PreferenceScreens. Each such (Sub)PreferenceScreen represents an account and has the account-username as its title. PreferenceScreen root = mgr.createPreferenceScreen(this); for (MyAccountClass account : myAccounts) { final PreferenceScreen accScreen = mgr.createPreferenceScreen(this); accScreen.setTitle(account.getUsername()); // add Preferences to the accScreen // (for instance a "change username"-preference) ... root.add(accScreen); } As the user enters sub-PreferenceScreen, and edits the account user-name, I want the outer PreferenceScreen to update it's PreferenceScreen-title for the account in question. I've tried to add... usernamePref.setOnPreferenceChangeListener(new OnPreferenceChangeListener() { public boolean onPreferenceChange(Preference preference, Object newValue) { accScreen.setTitle(newValue.toString()); return true; } }); ...but the accScreen.setTitle does not seem to take effect on the outer PreferenceScreen. I've note that calling onContentChanged(); actually makes it work, but I realize that this is probably not the preferred way of doing it. I suspect I should call postInvalidate() on some view somewhere, but I really can't figure out on what view and when to do it. http://stackoverflow.com/questions/2396153/preferencescreen-androidsummary-update may be experiening the same problem as me. Any help appreciated.

  • jquery ui autocomplete with database

    - by user301766
    I fairly new to JQuery and perhaps trying to achieve something that might be abit harder for a beginner. However I am trying to create an autocomplete that sends the current value to a PHP script and then returns the necessary values. Here is my Javascript code $("#login_name").autocomplete({ source: function(request, response) { $.ajax({ url: "http://www.myhost.com/myscript.php", dataType: "jsonp", success: function(data) { alert(data); response($.map(data, function(item) { return { label: item.user_login_name, value: item.user_id } })) } }) }, minLength: 2 }); And here is the the last half of "myscript.php" while($row = $Database->fetch(MYSQLI_ASSOC)) { foreach($row as $column=>$val) { $results[$i][$column] = $val; } $i++; } print json_encode($results); Which produces the following output [{"user_id":"2","user_login_name":"Name1"},{"user_id":"3","user_login_name":"Name2"},{"user_id":"4","user_login_name":"Name3"},{"user_id":"5","user_login_name":"Name4"},{"user_id":"6","user_login_name":"Name5"},{"user_id":"7","user_login_name":"Name6"}] Can anyone tell me where I am going wrong please? Starting to get quite frustrated. The input box just turns "white" and no options are shown. The code does work if I specify an array of values.

  • How to determine if an item is the last one in a WPF ItemTemplate?

    - by Mike
    Hi everyone, I have some XAML <ItemsControl Name="mItemsControl"> <ItemsControl.ItemTemplate> <DataTemplate> <TextBox Text="{Binding Mode=OneWay}" KeyUp="TextBox_KeyUp"/> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> that's bound to a simple ObservableCollection private ObservableCollection<string> mCollection = new ObservableCollection<string>(); public MainWindow() { InitializeComponent(); this.mCollection.Add("Test1"); this.mCollection.Add("Test2"); this.mItemsControl.ItemsSource = this.mCollection; } Upon hitting the enter key in the last TextBox, I want another TextBox to appear. I have code that does it, but there's a gap: private void TextBox_KeyUp(object sender, KeyEventArgs e) { if (e.Key != Key.Enter) { return; } TextBox textbox = (TextBox)sender; if (IsTextBoxTheLastOneInTheTemplate(textbox)) { this.mCollection.Add("A new textbox appears!"); } } The function IsTextBoxTheLastOneInTheTemplate() is something that I need, but can't figure out how to write. How would I go about writing it? I've considered using ItemsControl.ItemContainerGenerator, but can't put all the pieces together. Thanks! -Mike

  • How can I store HTML in a Doctrine YML fixture

    - by argibson
    I am working with a CMS-type site in Symfony 1.4 (Doctrine 1.2) and one of the things that is frustrating me is not being able to store HTML pages in YML fixtures. Instead I have to create SQL backups of the data if I want to drop and rebuild which is a bit of a pest when Symfony/Doctrine has a fantastic mechanism for doing exactly this. I could write a mechanism that reads in a set of HTML files for each page and fills the data in that way (or even write it as a task). But before I go down that road I am wondering if there is any way for HTML to be stored in a YML fixture so that Doctrine can simply import it into the database. Update: I have tried using symfony doctrine:data-dump and symfony doctrine:data-load however despite the dump correctly creating the fixture with the HTML, the load task appears to 'skip' the value of the column with the HTML and enters everything else into the row. In the database the field doesn't show up as 'NULL' but rather empty so I believe Doctrine is adding the value of the column as ''. Below is a sample of the YML fixture that symfony doctrine:data-dump created. I have tried running symfony doctrine:data-load against various forms of this including removing all the escaped characters (new lines and quotes leaving only angle brackets) but it still doesn't work. Product_69: name: 'My Product' Developer: Developer_30 tagline: 'Text that briefly describes the product' version: '2008' first_published: '' price_code: A79 summary: '' box_image: '' description: "<div id=\"featureSlider\">\n <ul class=\"slider\">\n <li class=\"sliderItem\" title=\"Summary\">\n <div class=\"feature\">\n Some text goes in here</div>\n </li>\n </ul>\n </div>\n" is_visible: true

  • ASP.NET-MVC Page: image logo is not displaying while sending the email

  • VS 2008 does not understand .resource files

    - by Dmitry
    I'm trying to add globalization support to my C# application. According to MSDN, there should be one embedded resource file for neutral culture and satellite DLLs with resource files for other cultures. I've created 2 satellite DLLs without any problems and got my app to automatically load right one using ResourceManager. But I can't embed default neutral culture resource file into my executable. When I remove all satellite DLLs or set culture to some culture I don't have satellite DLL for, I get exception "Could not find any resources appropriate for the specified culture or the neutral culture." when application attempts to create ResourceManager. It looks like VS 2008 does not include my .resource file into main assembly. I've tried different ways to get resource file embedded: compiling it by resgen.exe from text file and adding it to the project; changing its name to add second .resources extension; creating .resx file with same name; etc. And I still don't see the way to get resource file embedded and used by ResourceManager - I'm having same exception. What is the right way to add default neutral culture resource file to application in VS 2008 ?

  • LINQ Query to DataTable.DataSource

    - by lumberjack
    I am trying to perform a LINQ query on a DataTable and show the result in another DataTable. My source DataTable looks something like this: DataTable myDataTable = new DataTable(); myDataTable.Columns.Add("OrderID", typeof(int)); myDataTable.Columns.Add("Date", typeof(DateTime)); myDataTable.Columns.Add("UnitsPurchased", typeof(int)); The resulting DataTable looks like this when filled: Order ID Date Units Purchased 16548 10/15/09 250 17984 11/03/09 512 20349 01/11/10 213 34872 01/15/10 175 My current LINQ query looks like this: IEnumerable<DataRow> query = (from row in myDataTable.AsEnumerable() where row.UnitsPurchased > 200 select new { row.OrderID, row.Date, row.UnitsPurchased }) as IEnumerable<DataRow>; resultDataTable.DataSource = query.CopyToDataTable<DataRow>(); Every time I run this code query is null. I can see that that the as IEnumerable<DataRow> is the culprit, but it makes no since to me since DataTable.AsEnumerable() returns an IEnumerable<DataRow>. Any help would be appreciated.

  • Getting SSL to work with Apache/Passenger on OSX

    - by jonnii
    I use apache/passenger on my development machine, but need to add SSL support (something which isn't exposed through the control panel). I've done this before in production, but for some reason I can't seem to get it work on OSX. The steps I've followed so far are from a default apache osx install: Install passenger and passenger preference pane. Add my rails app (this works) Create my ca.key, server.crt and server.key as detailed on the apple website. At this point I need to start editing the apache configs, so I added: # Apache knows to listen on port 443 for ssl requests. Listen 443 Listen 80 I thought I'd try editing the passenger pref pane generated config first to get everything working, when I add: It starts off looking like this <VirtualHost *:80> ServerName myapp.local DocumentRoot "/Users/jonnii/programming/ruby/myapp/public" RailsEnv development <Directory "/Users/jonnii/programming/ruby/myapp/public"> Order allow,deny Allow from all </Directory> </VirtualHost> I then append this: <VirtualHost *:443> ServerName myapp.local DocumentRoot "/Users/jonnii/programming/ruby/myapp/public" RailsEnv development <directory "/Users/jonnii/programming/ruby/myapp/public"> Order allow,deny Allow from all </directory> # SSL Configuration SSLEngine on SSLCipherSuite ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP SSLOptions +FakeBasicAuth +ExportCertData +StdEnvVars +StrictRequire #Self Signed certificates SSLCertificateFile /private/etc/apache2/ssl.key/server.crt SSLCertificateKeyFile /private/etc/apache2/ssl.key/server.key SSLCertificateChainFile /private/etc/apache2/ssl.key/ca.crt SetEnvIf User-Agent ".*MSIE.*" nokeepalive ssl-unclean-shutdown downgrade-1.0 force-response-1.0 </VirtualHost> The files referenced all exist (I doubled checked that), but now when I restart my apache I can't even get to myapp.local. However apache can still server the default page when I click on it in the sharing preference panel. Any help would be greatly appreciated.

  • Kohana 3 ORM: How to get data from pivot table? and all other tables for that matter

    - by zenna
    I am trying to use ORM to access data stored, in three mysql tables 'users', 'items', and a pivot table for the many-many relationship: 'user_item' I followed the guidance from http://stackoverflow.com/questions/1946357/kohana-3-orm-read-additional-columns-in-pivot-tables and tried $user = ORM::factory('user',1); $user->items->find_all(); $user_item = ORM::factory('user_item', array('user_id' => $user, 'item_id' => $user->items)); if ($user_item->loaded()) { foreach ($user_item as $pivot) { print_r($pivot); } } But I get the SQL error: "Unknown column 'user_item.id' in 'order clause' [ SELECT user_item.* FROM user_item WHERE user_id = '1' AND item_id = '' ORDER BY user_item.id ASC LIMIT 1 ]" Which is clearly erroneous because Kohana is trying to order the elements by a column which doesn't exist: user_item.id. This id doesnt exist because the primary keys of this pivot table are the foreign keys of the two other tables, 'users' and 'items'. Trying to use: $user_item = ORM::factory('user_item', array('user_id' => $user, 'item_id' => $user->items)) ->order_by('item_id', 'ASC'); Makes no difference, as it seems the order_by() or any sql queries are ignored if the second argument of the factory is given. Another obvious error with that query is that the item_id = '', when it should contain all the elements. So my question is how can I get access to the data stored in the pivot table, and actually how can I get access to the all items held by a particular user as I even had problems with that? Thanks

  • How can I attach a file using Wordpress custom fields / meta boxes?

    - by shipshape
    I am using Wordpress's add_meta_box() function to add customized meta fields to the Add New Post page, like this. I want one of these fields to allow the user to upload a file, so that a single image, pdf, audio file, or video can be associated with the post. The closest example I've seen is this one. Unfortunately it does not suit my needs, as I want my file to be processed by Wordpress's Media Uploader - so it should appear in the Media Library afterwards, and thumbnails should be generated according to the Media settings. I think ideally there would be a way to tap into Wordpress's existing Add Media dialog, and simply output the URL of the uploaded file into a text box, but I don't see how to do that. This question is similar, but the answers are a little clunky - I would like to keep this super simple for my end users. How can I accomplish this? Please do not recommend plugins such as Flutter or Magic Fields - I have tried these and they do not suit my purposes (I want the images to be processed by Wordpress's Media Uploader). I am using Wordpress 3.0-alpha. Thanks!

  • How to handle missing files on MVC

    - by kaivalya
    What is your preferred way to handle hits to files that does not exist on your MVC app. I have couple of web apps runing with MVC and they are constantly getting hits for files folders etc. that does not exist in the app structure. Apps are throwing exception: The controller for path could not be found or it does not implement IController I am trying to find out the best way to handle this. I have 3 global routes on my global.asax file (see below) and at this point I am happy with that simple definition. I know if I added route definition for all controllers then I can add a definition to ignore the rest and handle these hits but if it will be possible to solve this problem without it, I do not want to add route definitions for each controller which I believe will flood the route definitions and also add a layer of maintenance which I don't like. //Aggregates 2nd level routes.MapRoute( "AggregateLevel2", "{controller}/{action}/{id}/{childid}/{childidlevel2}", new { controller = "Home", action = "Index", id = "", childid = "", childidlevel2 = "" } ); //Aggregates 1st level routes.MapRoute( "AggregateLevel1", "{controller}/{action}/{id}/{childid}", new { controller = "Home", action = "Index", id = "", childid = "" } ); routes.MapRoute( "Default", "{controller}/{action}/{id}", new { controller = "Home", action = "Index", id = "" } );

  • How do you jump to a particular row in a DataGridView by typing (a la Windows Explorer details view)

    - by russcollier
    I have a .NET Winforms app in C# with a DataGridView that's read-only and populated with some number of rows. I'd like to have functionality similar to Windows Explorer's (and many other applications) details view for example. I'd like the DataGridView to behave such that when it has focus if you start typing, the current row selection will jump to the row where the (string) value of cell 0 (i.e. the first column in the row) starts with the characters you typed in. For example, if I have a DataGridView with 1 column and the following rows: Bob Jane Jason John Leroy Sam If the DataGridView has focus and I hit the 'b' key on my keyboard, the selected row is now "Bob". If I quickly type in the keys 'ja', the selected row is Jane. If I quickly type in the letters 'jas', the selected row is Jane. If I hit the 'z' key, nothing is selected (since nothing starts with Z). Likewise if Jane is currently selected and I keep typing the letter 'j', the selection will cycle through to Jason, then John, then back to Jane, each time I hit the 'j' key. I've been doing some Googling (and "stackoverflowing" :-)) for awhile and cannot find any examples of this type of functionality. I have a rough idea in my head to do this via some sort of short lived timer thread, collecting the keystrokes on KeyPress events for the DataGridView, and selecting rows based on those collected keystrokes matching a Cells[0].Value.StartsWith() type of condition. But it seems like there has to be an easier way that I'm just not seeing. Any ideas would be much appreciated. Thanks!

Class popoverClass = NSClassFromString(@"UIPopoverController"); if(!popoverClass) { useNavController = YES; } else { if(currentPopover == nil || currentPopover.contentViewController != vc) { if(currentPopover != nil) { [currentPopover dismissPopoverAnimated:animated]; [currentPopover.delegate popoverControllerDidDismissPopover:currentPopover]; } UIPopoverController *popover = [[popoverClass alloc] initWithContentViewController:vc]; currentPopover = popover; currentPopover.delegate = self; [popover presentPopoverFromBarButtonItem:sender permittedArrowDirections:UIPopoverArrowDirectionAny animated:animated]; } } //[aPopover release]; } else { useNavController = YES; } if(useNavController) { if(modal) { [self presentModalViewController:vc animated:animated]; } else { [self.view addSubview:vc.view]; } } } Stepping with the debugger shows that the errors occur after [UIPopoverController presentPopoverFromBarButtonItem:permittedArrowDirections:animated: runs. Of note: The program continues running just fine No noticeable weirdness in UIImagePickerController's behavior when selecting an image or canceling Happens in Simulator 3.2 Unable to reproduce on iPad running 3.2 Is this just another simulator bug?

  • d:DesignData issue, Visual Studio 2010 cant build after adding sample design data with Expression Bl

    - by Valko
    Hi, VS 2010 solution and Silverlight project builds fine, then: I open MyView.xaml view in Expression Blend 4 Add sample data from class (I use my class defined in the same project) after I add new sample design data with Expression blend 4, everything looks fine, you see the added sample data in the EB 4 fine, you also see the data in VS 2010 designer too. Close the EB 4, and next VS 2010 build is giving me this errors: Error 7 XAML Namespace http://schemas.microsoft.com/expression/blend/2008 is not resolved. C:\Code\source\...myview.xaml and: Error 12 Object reference not set to an instance of an object. ... TestSampleData.xaml when I open the TestSampleData.xaml I see that namespace for my class used to define sample data is not recognized. However this namespace and the class itself exist in the same project! If I remove the design data from the MyView.xaml: d:DataContext="{d:DesignData /SampleData/TestSampleData.xaml}" it builds fine and the namespace in TestSampleData.xaml is recognized this time?? and then if add: d:DataContext="{d:DesignData /SampleData/TestSampleData.xaml}" I again see in the VS 2010 designer sample data, but the next build fails and again I see studio cant find the namespace in my TestSampleData.xaml containing sample data. That cycle is driving me crazy. Am I missing something here, is it not possible to have your class defining sample design data in the same project you have the MyView.xaml view?? cheers Valko

  • Any good tutorials or resources for learning how to design a scalable and "component" based game 'fr

    - by CodeJustin.com
    In short I'm creating a 2D mmorpg and unlike my last "mmo" I started developing I want to make sure that this one will scale well and work well when I want to add new in-game features or modify existing ones. With my last attempt with an avatar chat within the first few thousand lines of code and just getting basic features added into the game I seen my code quality lowering and my ability to add new features or modify old ones was getting lower too as I added more features in. It turned into one big mess that some how ran, lol. This time I really need to buckle down and find a design that will allow me to create a game framework that will be easy to add and remove features (aka things like playing mini-games within my world or a mail system or buddy list or a new public area with interactive items). I'm thinking that maybe a component based approach MIGHT be what I'm looking for but I'm really not sure. I have read documents on mmorpg design and 2d game engine architecture but nothing really explained a way of designing a game framework that will basically let me "plug-in" new features into the main game and use the resources of the main game without changing much within my 'main game code'. Hope someone understands what I mean, any help will is appreciated.

  • Sending mail issues. very confusing

    - by Dejan.S
    Hi my name is what, my name is who.. ops got carried away Now this might be a serverfault question and a stackoverflow question but I will go with it here because I don't really know the answer. I been sending mail a lot with asp.net before and never had problems like this before. I have setup a mail with this following code var list = new List<string> { "mail", "mail", "mail", "mail" }; var smtp = new SmtpClient("localhost", 25); var plainText = txtPlain.Text; var htmlText = Server.HtmlDecode(FCKeditor1.Value); foreach (var email in list) { var message = new MailMessage() { From = new MailAddress("my server mail"), ReplyTo = new MailAddress("mail") }; var mailMessage = Server.HtmlDecode(FCKeditor1.Value); message.To.Add(email); message.Subject = "Hi Enzorit"; message.Body = mailMessage; message.IsBodyHtml = true; message.BodyEncoding = System.Text.Encoding.GetEncoding("iso-8859-2"); var alternateViewHtml = AlternateView.CreateAlternateViewFromString(htmlText, null, MediaTypeNames.Text.Html); var alternateViewPlainText = AlternateView.CreateAlternateViewFromString(plainText, null, MediaTypeNames.Text.Plain); message.AlternateViews.Add(alternateViewHtml); message.AlternateViews.Add(alternateViewPlainText); smtp.Send(message); } now the issue becomes that some email clients get just plain while some get the html. Like on my hotmail on the computer i get the html but on my iphone i get the plain one. Why is that? and like that wasn't enough The mail wont deliver to some mails like any .pl email. Now here is where I am thinking that it might be a reverse DNS setup thing on my windows server 2008 issue + some company mails, it becomes spam, i had same issue with hotmail but that was solved when I added the plain. Anybody have had the problem before? I am very thankful for any answer I get.. thanks

  • Fulltext search on many tables

    - by Rob
    I have three tables, all of which have a column with a fulltext index. The user will enter search terms into a single text box, and then all three tables will be searched. This is better explained with an example: documents doc_id name FULLTEXT table2 id doc_id a_field FULLTEXT table3 id doc_id another_field FULLTEXT (I realise this looks stupid but that's because I've removed all the other fields and tables to simplify it). So basically I want to do a fulltext search on name, a_field and another_field, and then show the results as a list of documents, preferably with what caused that document to be found, e.g. if another_field matched, I would display what another_field is. I began working on a system whereby three fulltext search queries are performed and the results inserted into a table with a structure like: search_results table_name row_id score (This could later be made to cache results for a few days with e.g. a hash of the search terms). This idea has two problems. The first is that the same document can be in the search results up to three times with different scores. Instead of that, if the search term is matched in two tables, it should have one result, but a higher score. The second is that parsing the results is difficult. I want to display a list of documents, but I don't immediately know the doc_id without a join of some kind; however the table to join to is dependant on the table_name column, and I'm not sure how to accomplish that. Wanting to search multiple related tables like this must be a common thing, so I guess what I'm asking is am I approaching this in the right way? Can someone tell me the best way of doing it please.

  • Problem calling std::max

    - by Eric
    I compiled my bison-generated files in Visual Studio and got these errors: ...\position.hh(83): error C2589: '(' : illegal token on right side of '::' ...\position.hh(83): error C2059: syntax error : '::' ...\position.hh(83): error C2589: '(' : illegal token on right side of '::' ...\position.hh(83): error C2059: syntax error : '::' The corresponding code is: inline void columns (int count = 1) { column = std::max (1u, column + count); } I think the problem is with std::max; if I change std::max to equivalent code then there is no problem anymore, but is there a better solution instead of changing the generated code? Here is the bison file I wrote: // // bison.yy // %skeleton "lalr1.cc" %require "2.4.2" %defines %define parser_class_name "cmd_parser" %locations %debug %error-verbose %code requires { class ParserDriver; } %parse-param { ParserDriver& driver } %lex-param { ParserDriver& driver } %union { struct ast *a; double d; struct symbol *s; struct symlist *sl; int fn; } %code { #include "helper_func.h" #include "ParserDriver.h" std::string error_msg = ""; } %token <d> NUMBER %token <s> NAME %token <fn> FUNC %token EOL %token IF THEN ELSE WHILE DO LET %token SYM_TABLE_OVERFLOW %token UNKNOWN_CHARACTER %nonassoc <fn> CMP %right '=' %left '+' '-' %left '*' '/' %nonassoc '|' UMINUS %type <a> exp stmt list explist %type <sl> symlist %{ extern int yylex(yy::cmd_parser::semantic_type *yylval, yy::cmd_parser::location_type* yylloc); %} %start calclist %% ... grammar rules ...
