  • reuse of mvc view

    - by user344394
    I'm working on the MVC app where I've to generate the report in the form of HTML page. If the user click the print icon, I've to show the HTML page to user. If the user click on email icon, I've to send email with same HTML page attachment. I'm trying to find a way where I can use the same code to generate the HTML in both cases of email and print. Please provide your suggestions.

  • How to deal with class composition when components cannot be accessed from the outside?

    - by Chathuranga
    For example if I say I have three classes A, B, and C where B and C have a composition relation ship with A. That means the life of B and C is handled by A, and also B and C cannot access directly from the outside. For some reason my DataService class needs to return objects of B and C as It cant return a object of A as B and C cannot be initialized at the same time. (to be able to initializeC you have to initializeB first). So that I'm returning DataTables from DataService and then inside the class A those data tables are converted to B / C objects. If B and C objects cannot be initialized at the same time is it valid to say that B and C have a composition relationship with A? If its composition is it must to generate A with B and C inside? What is the proper way to handle this sort of a problem? EDIT: Following code explains the way I'm doing it now with DataTables. Example: class A { private List<B> B; private List <C> C; public A() { B= new List<B>(); C= new List<C>(); } public List<B> GetB( DataTable dt) { // Create a B list from dt return B; } } class Presenter { private void Show B() { _View.DataGrid = A.GetB(DataService.GetAListOfB()); } } The actual scenario is I have a class called WageInfo and classes Earning and Deduction having a composition relationship in the design. But for you to generate Deductions first you should Generate earnings and should be saved in a table. Then only you can generate deductions for the earnings to calculate balance wages. Also note that these contained classes have a one to many relationship with the containing class WageInfo. So actually WageInfo has a List<Earnings> and List<Deduction> My initial question was, is it ok if my DataService class returns Deductions / Earnings objects (actually lists) not a WageInfo? Still not clear?

  • Lack of ImageList in MenuStrip and performance issues

    - by Ivan
    MenuStrip doesn't support using ImageList images. What are performance issues of this? Are there chances of using too much GDI resources and slow-downs? How many items should be considered acceptable, after which one should implement custom control that draws images from ImageList?

In properties there's IgnoreDataMemberAttribute. I tried also reuse MyCommonClass type located in common project, but it is still generated

  • Translate RoR Code to Java

    - by mnml
    Hi, for some reasons I am trying to translate the following RoR view code to a Java Groovy view: <% modulo_artists = @artists.length % 3 base = @artists.length / 3 base = base.ceil case modulo_artists when 0 cols = [base, base, base] when 1 cols = [base, base + 1, base] when 2 cols = [base + 1, base, base + 1] end counter = 0 %> <% id_hash = {"0" => "url('/images/actorsbg.png');", "1" => "url('/images/musiciansbg.png');", "2" => "url('/images/artistsbg.png') no-repeat; color: #FFF;", "3" => "url('/images/fashionbg.png')"} %> <div id="artists_<%=params[:artist_cat]%>" style="background: <%= id_hash[params[:artist_cat]] %>;" > <table border="0" width="660" height="164" cellpadding="0" cellspacing="0"> <tr valign="middle"> <% 3.times do |i| %> <td width="220" align="center" style="padding-right: 15px;"> <% cols[i].times do %> <h1><a href="/artists/show/<%= @artists[counter].urlname %>" ><%= @artists[counter].name %></a></h1> <% counter = counter + 1 %> <% end %> </td> <% end %> </tr> </table> </div> This is what I got so far: #{extends 'main.html' /} %{ modulo_artists = artists.size() % 3 base = artists.size() / 3 base = Math.ceil(base) if(modulo_artists == 0) cols = [base, base, base] else if(modulo_artists == 1) cols = [base, base + 1, base] else if(modulo_artists == 2) cols = [base + 1, base, base + 1] endif counter = 0 }% <div id="artists_${artist_cat}" style="background:${id_hash};" > <table border="0" width="660" height="164" cellpadding="0" cellspacing="0"> <tr valign="middle"> #{list items:1..3, as:'i'} <td width="220" align="center" style="padding-right: 15px;"> #{list items:cols[i]} <h1><a href="@{Artists.show(artists.get(counter).name.replaceAll(" ", "-"))}" >${artists.get(counter).name}</a></h1> %{ counter = counter + 1 }% #{/list} </td> #{/list} </tr> </table> </div> The idea is to keep the items organised in 3 columns like 1|0|1 4|5|4 or 5|4|5 for example

  • IE7 not Caching CSS Image over SSL

    - by Alex
    Hello, I'm using the WebDevHelper toolbar for Internet Explorer to troubleshoot HTTP requests/roundtrips on my SSL site and noticed that IE re-downloads my CSS :hover images every time they are triggered. This causes a huge amount of roundtrips. How can I prevent this from happening? Edit: All static content is served with cache-control: public, so images, javascript etc. are cached in Firefox and Chrome. This problem is IE specific.

  • How to scale JPEG image down so that text is clear as possible?

    - by Juha Syrjälä
    I have some JPEG images that I need scale down to about 80% of original size. Original image dimension are about 700px × 1000px. Images contain some computer generated text and possibly some graphics (similar to what you would find in corporate word documents). How to scale image so that the text is as legible as possible? Currently we are scaling the imaeg down using bicubic interpolation, but that makes the text blurry and foggy.

  • iPhone Image Resources, ICO vs PNG, app bundle filesize

    - by Jasarien
    My application has a collection of around 1940 icons that are used throughout. They're currently in ICO and new images provided to me come in ICO format too. I have noticed that they contain a 16x16 and 32x32 representation of each icon in one file. Each file is roughly 4KB in filesize (as reported by finder, but ls reports that they vary from being ~1000 bytes to 5000 bytes) A very small number of these icons only contain the 32x32 representation, and as a result are only around 700 bytes in size. Currently I am bundling these icons with my application and they are inflating the size of the app a bit more than I would like. Altogether, the images total just about 25.5MB. Xcode must do some kind of compression because the resulting app bundle is about 12.4MB. Compressing this further into a ZIP (as it would be when submitted to the App Store), results in a final file of 5.8MB. I'm aware that the maximum limit for over the air App Store downloads has been raised to 20MB since the introduction of the iPad (I'm not sure if that extends to iPhone apps as well as iPad apps though, if not the limit would be 10MB). My worry is that new icons are going to be added (sometimes up to 10 icons per week), and will continue to inflate the app bundle over time. What is the best way to distribute these icons with my app? Things I've tried and not had much success with: Converting the icons from ICO to PNG: I tried this in the hopes that the pngcrush utility would help out with the filesize. But it appears that it doesn't make much of a difference between a normal PNG and a crushed png (I believe it just optimises the image for display on the iPhone's GPU rather than compress it's size). Also in going from ICO to PNG actually increased the size of the icon file... Zipping the images, and then uncompressing them on first run. While this did reduce the overall image sizes, I found that the effort needed to unzip them, copy them to the documents folder and ensure that duplication doesn't happen on upgrades was too much hassle to be worth the benefit. Also, on original and 3G iPhones unzipping and copying around 25MB of images takes too long and creates a bad experience... Things I've considered but not yet tried: Instead of distributing the icons within the app bundle, host them online, and download each icon on demand (it depends on the user's data as to which icons will actually be displayed and when). Issues with this is that bandwidth costs money, and image downloads will be bandwidth intensive. However, my app currently has a small userbase of around 5,500 users (of which I estimate around 1500 to be active based on Flurry stats), and I have a huge unused bandwidth allowance with my current hosting package. So I'm open to thoughts on how to solve this tricky issue.

  • PHP GD Allowed memory size exhausted

    - by gurun8
    I'm trying to process a directory of JPEG images (roughly 600+, ranging from 50k to 500k) using PHP: GD to resize and save the images but I've hit a bit of a snag quite early in the process. After correctly processing just 3 images (30K, 18K and 231K) I get a Allowed memory size of 16777216 bytes exhausted PHP Fatal error. I'm cycling through the images and calling the code below: list($w, $h) = getimagesize($src); if ($w > $it->width) { $newwidth = $it->width; $newheight = round(($newwidth * $h) / $w); } elseif ($w > $it->height) { $newheight = $it->height; $newwidth = round(($newheight * $w) / $h); } else { $newwidth = $w; $newheight = $h; } // create resize image $img = imagecreatetruecolor($newwidth, $newheight); $org = imagecreatefromjpeg($src); // Resize imagecopyresized($img, $org, 0, 0, 0, 0, $newwidth, $newheight, $w, $h); imagedestroy($org); imagejpeg($img, $dest); // Free up memory imagedestroy($img); I've tried to free up memory with the imagedestroy function but it doesn't seem to have any affect. The script just keeps consistently choking at the imagecreatefromjpeg line of code. I checked the php.ini and the memory_limit = 16M setting seems like it's holding correctly. But I can't figure out why the memory is filling up. Shouldn't it be releasing the memory back to the garbage collector? I don't really want to increase the memory_limit setting. This seems like a bad workaround that could potentially lead to more issues in the future. FYI: I'm running my script from a command prompt. It shouldn't affect the functionality but might influence your response so I thought I should mention it. Can anyone see if I'm just missing something simple or if there's a design flaw here? You'd think that this would be a pretty straightforward task. Surely this has to be possible, right?

  • How do I create a Web Service in Visual Studio.NET using a WSDL file?

    - by myermian
    I'm trying to use a WSDL Top Down approach to create a Web Service in Visual Studio 2010. I used Eclipse's WSDL GUI Editor to generate a WSDL file (CalculatorWSDL.wsdl) which uses the SOAP method for communication. I also used wsdl.exe to generate a C# file (Calculator.cs). Now, I'm not sure what to do next. How do I actually use the Calculator.cs on the server and/or client?

  • Using URI-fragments in Ruby on rails routing

    - by Alexei
    RoR application can generate URL such as /post/10. But now I want to create a site, which works with URI-fragments like gmail. For example gmail uses the following URLs https://mail.google.com/mail/?shva=1#sent https://mail.google.com/mail/?shva=1#label/books I need to generate URL such as /#/post/10, where controller = "post", action = "show", id = "10". Of course it will be good to use standard url-helpers.

  • Displaying an image from the tmp directory

    - by Roland
    I have the following. A website that create temporarily images in the /tmp folder on the Linux server. The reason why I store it within this folder is since these images need to be cleared once in a while and it's so much easier just to clear the tmp directory using tmpwatch. Now my issue is to display the image within my browser? Code <img src="/tmp/3d34636.png" alt="image" /> I'm running Centos with PHP
