  • How to use another type of EditingControl in a single C# 3.5 DataGridView column ?

    - by too
    Is this possible to have two (or more) different kinds of cells to be displayed interchangeably in single column of C# .Net 3.5 DataGridView? I know one column has specified single EditingControl type, yet I think grid is flexible enough to do some tricks, I may think of only: Adding as many invisible columns to grid as required types of cells and on CellBeginEdit somehow exchange current cell with other column's cell Create custom column and custom cell with possibility of changing EditingControl for single cell Which approach is better, are there any examples ?

  • OpenMP implementations in VC++ 2008, 2010

    - by John
    Depending on implementation, OMP can be quite useful to parallelize fairly arbitrary bits of code - e.g a parallel section inside a method that calls two independent methods - or it can be bad. It depends on how threads are created/cached, I think. How does the VC++ 2008 implementation work? And is the 2010 implementation significantly different in terms of features and performance/flexibility?

  • Rails caches_page :index in Wrong Location

    - by Andy
    I have a controller Projects in my Rails app with: caches_page :index However, instead of the cached file being generated at /public/projects/index.html it is located at /public/projects.html. The web server (currently Mongrel) looks for */ directories before *.html files. So the http://…/projects request is routed through Rails and my index cache file is never served. How can I tell caches_page :index to generate the file at /public/projects/index.html instead?

  • How do I create/use a Fluent NHibernate convention to automap UInt32 properties to an SQL Server 200

    - by dommer
    I'm trying to use a convention to map UInt32 properties to a SQL Server 2008 database. I don't seem to be able to create a solution based on existing web sources, due to updates in the way Fluent NHibernate works - i.e. examples are out of date. I'm trying to have NHibernate generate the schema (via ExposeConfiguration). I'm happy to have NHibernate map it to anything sensible (e.g. bigint). Here's my code as it currently stands (which, when I try to expose the schema, fails due to SQL Server not supporting UInt32).

  • MySQL Single Query Benchmarking Strategies

    - by Pepper
    Hello, I have a slow mySQL query in my application that I need to re-write. The problem is, it's only slow on my production server and only when it's not cached. The first time I run it, it will take 12 seconds, then anytime after that it'll be 500 milliseconds. Is there an easy way to test this query without it hitting the query cache so I can see the results of my refactoring? Thanks!

  • How do I create/use a Fluent NHibernate convention to map UInt32 properties to an SQL Server 2008 da

    - by dommer
    I'm trying to use a convention to map UInt32 properties to a SQL Server 2008 database. I don't seem to be able to create a solution based on existing web sources, due to updates in the way Fluent NHibernate works - i.e. examples are out of date. Here's my code as it currently stands (which, when I try to expose the schema, fails due to SQL Server not supporting UInt32). Apologies for the code being a little long, but I'm not 100% sure what is relevant to the problem, so I'm erring on the side of caution. I think I'll need a relatively comprehensive example, as I don't seem to be able to pull the pieces together into a working solution, at present. FluentConfiguration configuration = Fluently.Configure() .Database(MsSqlConfiguration.MsSql2008 .ConnectionString(connectionString)) .Mappings(mapping => mapping.AutoMappings.Add( AutoMap.AssemblyOf<Product>() .Conventions.Add<UInt32UserTypeConvention>())); configuration.ExposeConfiguration(x => new SchemaExport(x).Create(false, true)); namespace NHibernateTest { public class UInt32UserTypeConvention : UserTypeConvention<UInt32UserType> { // Empty. } } namespace NHibernateTest { public class UInt32UserType : IUserType { // Public properties. public bool IsMutable { get { return false; } } public Type ReturnedType { get { return typeof(UInt32); } } public SqlType[] SqlTypes { get { return new SqlType[] { SqlTypeFactory.Int32 }; } } // Public methods. public object Assemble(object cached, object owner) { return cached; } public object DeepCopy(object value) { return value; } public object Disassemble(object value) { return value; } public new bool Equals(object x, object y) { return (x != null && x.Equals(y)); } public int GetHashCode(object x) { return x.GetHashCode(); } public object NullSafeGet(IDataReader rs, string[] names, object owner) { int? i = (int?)NHibernateUtil.Int32.NullSafeGet(rs, names[0]); return (UInt32?)i; } public void NullSafeSet(IDbCommand cmd, object value, int index) { UInt32? u = (UInt32?)value; int? i = (Int32?)u; NHibernateUtil.Int32.NullSafeSet(cmd, i, index); } public object Replace(object original, object target, object owner) { return original; } } }

  • Using ImageMagick to create an image from a PDF...efficiently

    - by bigsweater
    I'm using ImageMagick to create a tiny JPG thumbnail image of an already-uploaded PDF. The code works fine. It's a WordPress widget, though this isn't necessarily WordPress specific. I'm unfamiliar with ImageMagick, so I was hoping somebody could tell me if this looks terrible or isn't following some best practices of some sort, or if I'm risking crashing the server. My questions, specifically, are: Is that image cached, or does the server have to re-generate the image every time somebody views the page? If it isn't cached, what's the best way to make sure the server doesn't have to regenerate the thumbnail? I tried to create a separate folder (/thumbs) for ImageMagick to put all the images in, instead of cluttering up the WP upload folders with images of PDFs. It kept throwing a permission error, despite 777 permissions on the folder in my testing environment. Why? Do the source/destination directories have to be the same? Am I doing anything incorrectly/inefficiently here that needs to be improved? The whole widget is on Pastebin: http://pastebin.com/WnSTEDm7 Relevant code: <?php if ( $url ) { $pdf = $url; $info = pathinfo($pdf); $filename = basename($pdf,'.'.$info['extension']); $uploads = wp_upload_dir(); $file_path = str_replace( $uploads['baseurl'], $uploads['basedir'], $url ); $dest_path = str_replace( '.pdf', '.jpg', $file_path ); $dest_url = str_replace( '.pdf', '.jpg', $pdf ); exec("convert \"{$file_path}[0]\" -colorspace RGB -geometry 60 $dest_path"); ?> <div class="entry"> <div class="widgetImg"> <p><a href="<?php echo $url; ?>" title="<?php echo $filename; ?>"><?php echo "<img src='".$dest_url."' alt='".$filename."' class='blueBorder' />"; ?></a></p> </div> <div class="widgetText"> <?php echo wpautop( $desc ); ?> <p><a class="downloadLink" href="<?php echo $url; ?>" title="<?php echo $filename; ?>">Download</a></p> </div> </div> <?php } ?> As you can see, the widget grabs whatever PDF is attached to the current page being viewed, creates an image of the first page of the PDF, stores it, then links to it in HTML. Thanks for any and all help!

  • Correct way to read configuration file and using configuration values

    - by Harza
    I'm reading applications .config file using .NET ConfigurationManager like it should be done, but .... Which one is most preferred option: Read config and store instance of (build in or custom) ConfigurationElement for later use Read config and store only needed values (but not instances of ConfigrationElement classes) for later use Read ConfigurationElement from config always when configuration values are needed These two things are in my mind: Performance impact in case 3 when reading config all the time Problems occuring in case 1 when using cached instances of ConfigurationElements

    I'd like to know if listing a set of partner sites/blogs is useful for the pagerank growth. Does Google see it as an incorrect act? I read somewhere that if people exchange links, google seeks it and marks as a bad technique. If it doesn't matter, is the content of the linked site relevant?

  • Is a Multi-DAL Approach the way to go here?

    - by Krisc
    Working on the data access / model layer in this little MVC2 project and trying to think things out to future projects. I have a database with some basic tables and I have classes in the model layer that represent them. I obviously need something to connect the two. The easiest is to provide some sort of 'provider' that can run operations on the database and return objects. But this is for a website that would potentially be used "a lot" (I know, very general) so I want to cache results from the data layer and keep the cache updated as new data is generated. This question deals with how best to approach this problem of dual DALS. One that returns cached data when possible and goes to the data layer when there is a cache miss. But more importantly, how to integrate the core provider (thing that goes into database) with the caching layer so that it too can rely on cached objects rather than creating new ones. Right now I have the following interfaces: IDataProvider is used to reach the database. It doesn't concern itself with the meaning of the objects it produces, but simply the way to produce them. interface IDataProvider{ // Select, Update, Create, et cetera access IEnumerable<Entry> GetEntries(); Entry GetEntryById(int id); } IDataManager is a layer that sits on top of the IDataProvider layer and manages the cache interface IDataManager : IDataProvider{ void ClearCache(); } Note that in practice the IDataManager implementation will have useful helper functions to add objects to their related cache stores. (In the future I may define other functions on the interface) I guess what I am looking for is the best way to approach a loop back from the IDataProvider implementations so that they can access the cache. Or a different approach entirely may be in order? I am not very interested in 3rd party products at the moment as I am interested in the design of these things much more than this specific implementation. Edit: I realize the title may be a bit misleading. I apologize for that... not sure what to call this question.

  • HTML5 Offline Storage on iPad and iPhone BUG

    - by scaraveos
    Hello everyone, I created a manifest file with 1000 items. Safari, Mozilla browsers are saving the files offline successfully and even Android saves the files correctly offline. On iPad and iPhone when I am trying to save more than 300 items in some point the applicationCache returns "error". When I am trying to save less (e.x.: 200) it saves the files correctly and the applicationCache returns "cached". Any ideas? Thank you.

  • Action Cache for root URL not working

    - by askegg
    Here's the setup. I have web site which is essentially a simple CMS. Here is the routes file: map.connect ':url', :controller => :pages, :action => :show map.root :controller => :pages, :action => :show, :url => "/" The page controller is thus: class PagesController < ApplicationController before_filter :verify_access, :except => [:show] # Cache show action if we are not logged in. caches_action :show, :layout => false, :unless => Proc.new { |controller| controller.logged_in? } def update @page = Page.find(params[:id]) respond_to do |format| expire_action :action => :show, :url => @page.url So when a visitor hits "/" it maps to :controller = "pages, :action = "show, :url = "/". This generates a cached version on first try, then returns the appropriate result there after. The log files show: Processing PagesController#show (for 127.0.0.1 at 2009-08-02 14:15:01) [GET] Parameters: {"action"=>"show", "url"=>"/", "controller"=>"pages"} Cached fragment hit: views/out.local// (0.1ms) Rendering template within layouts/application Filter chain halted as [#<ActionController::Filters::AroundFilter:0x23eb03c @identifier=nil, @method=#<Proc:0x01904858@/Library/Ruby/Gems/1.8/gems/actionpack-2.3.3/lib/action_controller/caching/actions.rb:64>, @kind=:filter, @options={:only=>#<Set: {"show"}>, :if=>nil, :unless=>#<Proc:0x025137ac@/Users/askegg/Sites/out/app/controllers/pages_controller.rb:6>}>] did_not_yield. Completed in 2ms (View: 1, DB: 0) | 200 OK [http://out.local/] OK - all good so far. When I update the page, it should expire the cache (see above). The logs show: Page Load (0.2ms) SELECT * FROM "pages" WHERE ("pages"."id" = 3) Page Load (0.1ms) SELECT "pages".id FROM "pages" WHERE ("pages"."url" = '/' AND "pages".domain_id = 1 AND "pages".id <> 3) LIMIT 1 Expired fragment: views/out.local/index (0.1ms) Redirected to http://out.local/pages/3 Completed in 9ms (DB: 0) | 302 Found [http://out.local/pages/3] See the problem? Rails is clearing the cache named "index", but it sets it as "/". Naturally this results in the cache NOT being cleared, so visitors are now seeing the old version.

  • No IO exception reported for socket operation when the interface is removed

    - by user352536
    The wifi network is connected, the application setup a socket connection and exchange data with the remote server. But when turn off the wifi, the inteface is removed, while socket operation read/write on this socket is still like normal, no any IO exception reported. The application has to do some extra checking to avoid waiting for the data forever. Is this the normal case for Android design? Is there any plan to fix it?
