  • Where is the "ListViewItemPlaceholderBackgroundThemeBrush" located?

    - by Dimi Toulakis
    I have a problem understanding one style definition in Windows 8 metro apps. When you create a metro style application with VS, there is also a folder named Common created. Inside this folder there is file called StandardStyles.xaml Now the following snippet is from this file: <!-- Grid-appropriate 250 pixel square item template as seen in the GroupedItemsPage and ItemsPage --> <DataTemplate x:Key="Standard250x250ItemTemplate"> <Grid HorizontalAlignment="Left" Width="250" Height="250"> <Border Background="{StaticResource ListViewItemPlaceholderBackgroundThemeBrush}"> <Image Source="{Binding Image}" Stretch="UniformToFill"/> </Border> <StackPanel VerticalAlignment="Bottom" Background="{StaticResource ListViewItemOverlayBackgroundThemeBrush}"> <TextBlock Text="{Binding Title}" Foreground="{StaticResource ListViewItemOverlayForegroundThemeBrush}" Style="{StaticResource TitleTextStyle}" Height="60" Margin="15,0,15,0"/> <TextBlock Text="{Binding Subtitle}" Foreground="{StaticResource ListViewItemOverlaySecondaryForegroundThemeBrush}" Style="{StaticResource CaptionTextStyle}" TextWrapping="NoWrap" Margin="15,0,15,10"/> </StackPanel> </Grid> </DataTemplate> What I do not understand here is the static resource definition, e.g. for the Border Background="{StaticResource ListViewItemPlaceholderBackgroundThemeBrush}" It is not about how you work with templates and binding and resources. Where is this ListViewItemPlaceholderBackgroundThemeBrush located? Many thanks for your help. Dimi

  • C++ interpreter conceptual problem

    - by Jan Wilkins
    I've built an interpreter in C++ for a language created by me. One main problem in the design was that I had two different types in the language: number and string. So I have to pass around a struct like: class myInterpreterValue { myInterpreterType type; int intValue; string strValue; } Objects of this class are passed around million times a second during e.g.: a countdown loop in my language. Profiling pointed out: 85% of the performance is eaten by the allocation function of the string template. This is pretty clear to me: My interpreter has bad design and doesn't use pointers enough. Yet, I don't have an option: I can't use pointers in most cases as I just have to make copies. How to do something against this? Is a class like this a better idea? vector<string> strTable; vector<int> intTable; class myInterpreterValue { myInterpreterType type; int locationInTable; } So the class only knows what type it represents and the position in the table This however again has disadvantages: I'd have to add temporary values to the string/int vector table and then remove them again, this would eat a lot of performance again. Help, how do interpreters of languages like Python or Ruby do that? They somehow need a struct that represents a value in the language like something that can either be int or string.

  • Rails: Rendered JS file doesn't execute using UJS

    - by Hassinus
    I would like to display a Rails edit form using JS instead of redirecting with HTML. To do this, I use UJS for the edit link: <%= link_to "Edit user info", edit_user_path(1), :remote => true %> Then, the "edit" action of User controller is like this (simplified version): controllers/users_controller.rb: def edit # Step 1: Get the edit HTML form @html = render_to_string(:template => "users/edit.html") # Step 2: Use JS to display the form in the correct place render "users/edit.js" end As you may guess, I have two views: The html version of "edit" action which contains the form in HTML format. Let's consider a test version: views/users/edit.html.erb: <h1>This is just a test</h1> The js version that will display the form in the correct place, using jQuery for example. Again, for test purpose, let's just popup the html text: views/users/edit.js.erb: alert("<%= @html %>"); The problem is that nothing is executed (no popup) Using the inspector (from Chrome web browser), I get the response as text format: alert("<h1>This is just a test</h1>"); Do you have any idea? Why do the rendered JS is not executed? Thanks in advance.

  • Grails g:paginate tag and custom URL

    - by aboxy
    Hello, I am trying to use g:paginate in a shared template where depending on the controller, url changes e.g. For my homepage url should be : mydomain[DOT]com/news/recent/(1..n) For search Page: www[DOT]mydomain[DOT]com/search/query/"ipad apps"/filter/this month and my g:paginate looks like this: g:paginate controller=${customeController} action=${customAction} total:${total} For the first case, I was able to provide controller as 'news' and action as 'recent' and mapped url /news/recent/$offset to my controller. But for the search page, I am not able to achieve what I want to do. I have a URL mapping defined as /search/$filter**(controller:"search",action:"fetch") $filter can be /query/"ipad apps"/filter/thismonth/filter/something/filter/somethingelse. I want to be able to show the url as above rather than ?query="ipad apps"&filter=thismonth&filter=something&filter=somethingelse. I believe I can pass all the parameters in params attribute of g:paginate but that will not give me pretty URL. What would be the best way to achieve this? Please feel free to ask questions If i missed anything.Thanks in advance.

  • How to store session values with Node.js and mongodb?

    - by Tirithen
    How do I get sessions working with Node.js, [email protected] and mongodb? I'm now trying to use connect-mongo like this: var config = require('../config'), express = require('express'), MongoStore = require('connect-mongo'), server = express.createServer(); server.configure(function() { server.use(express.logger()); server.use(express.methodOverride()); server.use(express.static(config.staticPath)); server.use(express.bodyParser()); server.use(express.cookieParser()); server.use(express.session({ store: new MongoStore({ db: config.db }), secret: config.salt })); }); server.configure('development', function() { server.use(express.errorHandler({ dumpExceptions: true, showStack: true })); }); server.configure('production', function() { server.use(express.errorHandler()); }); server.set('views', __dirname + '/../views'); server.set('view engine', 'jade'); server.listen(config.port); I'm then, in a server.get callback trying to use req.session.test = 'hello'; to store that value in the session, but it's not stored between the requests. It probobly takes something more that this to store session values, how? Is there a better documented module than connect-mongo?

  • using jquery selector to change attribute in variable returned from ajax request

    - by Blake
    I'm trying to pull in a filename.txt (contains html) using ajax and change the src path in the data variable before I load it into the target div. If I first load it into the div the browser first requests the broken image and I don't want this so I would like to do my processing before I load anything onto the page. I can pull the src values fine but I can't change them. In this example the src values aren't changed. Is there a way to do this with selectors or can they only modify DOM elements? Otherwise I may have to do some regex replace but using a selector will be more convenient if possible. $.ajax( { url: getDate+'/'+name+'.txt', success: function(data) { $('img', data).attr('src', 'new_test_src'); $('#'+target).fadeOut('slow', function(){ $('#'+target).html(data); $('#'+target).fadeIn('slow'); }); } }); My reason is I'm building a fully standalone javascript template system for a newsletter and since images and other things are upload via a drupal web file manager I want the content creators to keep their paths very short and simple and I can then modify them before I load in the content. This will also be distributed on a CD so I can need to change the paths for that so they still work.

  • Checking if a console application is still running using the Process class

    - by Ced
    I'm making an application that will monitor the state of another process and restart it when it stops responding, exits, or throws an error. However, I'm having trouble to make it reliably check if the process (Being a C++ Console window) has stopped responding. My code looks like this: public void monitorserver() { while (true) { server.StartInfo = new ProcessStartInfo(textbox_srcdsexe.Text, startstring); server.Start(); log("server started"); log("Monitor started."); while (server.Responding) { if (server.HasExited) { log("server exitted, Restarting."); break; } log("server is running: " + server.Responding.ToString()); Thread.Sleep(1000); } log("Server stopped responding, terminating.."); try { server.Kill(); } catch (Exception) { } } } The application I'm monitoring is Valve's Source Dedicated Server, running Garry's Mod, and I'm over stressing the physics engine to simulate it stopping responding. However, this never triggers the process class recognizing it as 'stopped responding'. I know there are ways to directly query the source server using their own protocol, but i'd like to keep it simple and universal (So that i can maybe use it for different applications in the future). Any help appreciated

  • Using NULLs in matchup table

    - by TomWilsonFL
    I am working on the accounting portion of a reservation system (think limo company). In the system there are multiple objects that can either be paid or submit a payment. I am tracking all of these "transactions" in three tables called: tx, tx_cc, and tx_ch. tx generates a new tx_id (for transaction ID) and keeps the information about amount, validity, etc. Tx_cc and tx_ch keep the information about the credit card or check used, respectively, which link to other tables (credit_card and bank_account among others). This seems fairly normalized to me, no? Now here is my problem: The payment transaction can take place for a myriad of reasons. Either a reservation is being paid for, a travel agent that booked a reservation is being paid, a driver is being paid, etc. This results in multiple tables, one for each of the entities: agent_tx, driver_tx, reservation_tx, etc. They look like this: CREATE TABLE IF NOT EXISTS `driver_tx` ( `tx_id` int(10) unsigned zerofill NOT NULL, `driver_id` int(11) NOT NULL, `reservation_id` int(11) default NULL, `reservation_item_id` int(11) default NULL, PRIMARY KEY (`tx_id`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8; Now this transaction is for a driver, but could be applied to an individual item on the reservation or the entire reservation overall. Therefore I demand either reservation_id OR reservation_item_id to be null. In the future there may be other things which a driver is paid for, which I would also add to this table, defaulting to null. What is the rule on this? Opinion? Obviously I could break this out into MANY three column tables, but the amount of OUTER JOINing needed seems outrageous. Your input is appreciated. Peace, Tom

  • Skip HTML escape in custom label_tag helper in Rail 3

    - by tricote
    Hi, I have this nice class ErrorFormBuilder that allows me to add the error description near the corresponding field in the form view : class ErrorFormBuilder < ActionView::Helpers::FormBuilder #Adds error message directly inline to a form label #Accepts all the options normall passed to form.label as well as: # :hide_errors - true if you don't want errors displayed on this label # :additional_text - Will add additional text after the error message or after the label if no errors def label(method, text = nil, options = {}) #Check to see if text for this label has been supplied and humanize the field name if not. text = text || method.to_s.humanize #Get a reference to the model object object = @template.instance_variable_get("@#{@object_name}") #Make sure we have an object and we're not told to hide errors for this label unless object.nil? || options[:hide_errors] #Check if there are any errors for this field in the model errors = object.errors.on(method.to_sym) if errors #Generate the label using the text as well as the error message wrapped in a span with error class text += " <br/><span class=\"error\">#{errors.is_a?(Array) ? errors.first : errors}</span>" end end #Add any additional text that might be needed on the label text += " #{options[:additional_text]}" if options[:additional_text] #Finally hand off to super to deal with the display of the label super(method, text, options) end end But the HTML : text += " <br/><span class=\"error\">#{errors.is_a?(Array) ? errors.first : errors}</span>" is escaped by default in the view... I tried to add the {:escape = false} option : super(method, text, options.merge({:escape => false})) without success Is there any way to bypass this behavior ? Thanks

  • How to efficiently compare the sign of two floating-point values while handling negative zeros

    - by François Beaune
    Given two floating-point numbers, I'm looking for an efficient way to check if they have the same sign, given that if any of the two values is zero (+0.0 or -0.0), they should be considered to have the same sign. For instance, SameSign(1.0, 2.0) should return true SameSign(-1.0, -2.0) should return true SameSign(-1.0, 2.0) should return false SameSign(0.0, 1.0) should return true SameSign(0.0, -1.0) should return true SameSign(-0.0, 1.0) should return true SameSign(-0.0, -1.0) should return true A naive but correct implementation of SameSign in C++ would be: bool SameSign(float a, float b) { if (fabs(a) == 0.0f || fabs(b) == 0.0f) return true; return (a >= 0.0f) == (b >= 0.0f); } Assuming the IEEE floating-point model, here's a variant of SameSign that compiles to branchless code (at least with with Visual C++ 2008): bool SameSign(float a, float b) { int ia = binary_cast<int>(a); int ib = binary_cast<int>(b); int az = (ia & 0x7FFFFFFF) == 0; int bz = (ib & 0x7FFFFFFF) == 0; int ab = (ia ^ ib) >= 0; return (az | bz | ab) != 0; } with binary_cast defined as follow: template <typename Target, typename Source> inline Target binary_cast(Source s) { union { Source m_source; Target m_target; } u; u.m_source = s; return u.m_target; } I'm looking for two things: A faster, more efficient implementation of SameSign, using bit tricks, FPU tricks or even SSE intrinsics. An efficient extension of SameSign to three values.

  • Determining when stringByEvaluatingJavaScriptFromString has finished

    - by alku83
    I have a UIWebView which loads up an HTML page. This page has two buttons on it, say Exit and Submit. I don't want users to be able to click the Exit button, so once the page has finished loading (ie. webViewDidFinishLoad is called), I use stringByEvaluatingJavaScriptFromString to remove one of these buttons, by manipulating the HTML. I also disable user interaction on the UIWebView on webViewDidStartLoad, and enable it again on webViewDidFinishLoad. The problem I am finding is that stringByEvaluatingJavaScriptFromString takes a second or two to complete, and it seems to be done in it's own thread. So what is happening is that webViewDidFinishLoad is called, user interaction is enabled on the UIWebView, and if the user is quick, they can click the Exit button before stringByEvaluatingJavaScriptFromString has finished. As stringByEvaluatingJavaScriptFromString seems to be on it's own thread with no way to know when it's finished (it doesnt call webViewDidFinishLoad), the only way to completely prevent users from tapping the Exit button that I can see is to only enable user interaction on the UIWebView after some delay, which is unreliable (how can I really know how long to delay for?). Am I correct in that stringByEvaluatingJavaScriptFromString is done on it's on thread, and I have no way of being able to tell when it's finished? Any other suggestions for how to get around this problem? EDIT: In short, what I want to know is if it is possible to disable a UIWebView while stringByEvaluatingJavaScriptFromString is executing, and re-enable the UIWebView when the javascript is finished. EDIT 2: There's an article here which seems to imply you can somehow poll the JS engine to see when it's finished, but I can't find any other references saying the same thing: http://drnicwilliams.com/2008/11/10/to-webkit-or-not-to-webkit-within-your-iphone-app/ EDIT 3 Based on the answer from Brad Smith, it seems that I actually need to know when the UIWebView has finished loading itself after the javascript has executed. It's looking more and more like I just need to put a delay of sorts in there.

  • Best practices for withstanding launch day traffic burst

    - by Sam McAfee
    We are working on a website for a client that (for once) is expected to get a fair amount of traffic on day one. There are press releases, people are blogging about it, etc. I am a little concerned that we're going to fall flat on our face on day one. What are the main things you would look at to ensure (in advance without real traffic data) that you can stay standing after a big launch. Details: This is a L/A/M/PHP stack, using an internally developed MVC framework. This is currently being launched on one server, with Apache and MySQL both on it, but we can break that up if need be. We are already installing memcached and doing as much PHP-level caching as we can think of. Some of the pages are rather query intensive, and we are using Smarty as our template engine. Keep in mind there is no time to change any of these major aspects--this is the just the setup. What sorts of things should we watch out for?

  • Boost Binary Endian parser not working?

    - by Hai
    I am studying how to use boost spirit Qi binary endian parser. I write a small test parser program according to here and basics examples, but it doesn't work proper. It gave me the msg:"Error:no match". Here is my code. #include "boost/spirit/include/qi.hpp" #include "boost/spirit/include/phoenix_core.hpp" #include "boost/spirit/include/phoenix_operator.hpp" #include "boost/spirit/include/qi_binary.hpp" // parsing binary data in various endianness template '<'typename P, typename T void binary_parser( char const* input, P const& endian_word_type, T& voxel, bool full_match = true) { using boost::spirit::qi::parse; char const* f(input); char const* l(f + strlen(f)); bool result1 = parse(f,l,endian_word_type,voxel); bool result2 =((!full_match) || (f ==l)); if ( result1 && result2) { //doing nothing, parsing data is pass to voxel alreay } else { std::cerr << "Error: not match!!" << std::endl; exit(1); } } typedef boost::uint16_t bs_int16; typedef boost::uint32_t bs_int32; int main ( int argc, char *argv[] ) { namespace qi = boost::spirit::qi; namespace ascii = boost::spirit::ascii; using qi::big_word; using qi::big_dword; boost::uint32_t ui; float uf; binary_parser("\x01\x02\x03\x04",big_word,ui); assert(ui=0x01020304); binary_parser("\x01\x02\x03\x04",big_word,uf); assert(uf=0x01020304); return 0; }' I almost copy the example, but why this binary parser doesn't work.

  • Giving writing permissions for IIS user at Windows 2003 Server

    I am running a website over Windows 2003 Server and IIS6 and I am having problems to write or delete files in some temporary folder obtaining this kind of warmings: Warning: unlink(C:\Inetpub\wwwroot\cakephp\app\tmp\cache\persistent\myapp_cake_core_cake_): Permission denied in C:\Inetpub\wwwroot\cakephp\lib\Cake\Cache\Engine\FileEngine.php on line 254 I went to the tmp directory and at the properties I gave the IIS User the following permissions: Read & Execute List folder Contents Read And it still showing the same warnings. When I am on the properties window, if I click on Advanced the IIS username appears twice. One with Allow type and read & execute permissions and the other with Deny type and Special permissions. My question is: Should I give this user not only the Read & Execute permissions but also this ones?: Create Attributes Create Files/ Write Data Create Folders/ Append Data Delete Subfolders and Files Delete They are available to select if I Click on the edit button over the username. Wouldn't I be opening a security hole if I do this? Otherwise, how can I do to read and delete the files my website uses? Thanks.

  • JMeter CSV Data Set is corrupting Japanese strings stored as proper UTF-8, I get Question Marks instead

    - by Mark Bennett
    I read in search terms from a simple text file to send to a search engine. It works fine in English, but gives me ???? for any Japanese text. Text with mixed English and Japanese does show the English text, so I know it's reading it. What I'm seeing: Input text: Snow Leopard ??????????????? Turns into: Snow Leopard ??????????????? This is in my POST field of an HTTP. If I set JMeter to encode the data, it just puts in the percent sequence for question marks. Interesting note: In the example above there are 15 Japanese characters, and then 15 question marks, so at some point it's being seen as full characters and not just bytes. About the Data: The CSV file is very simple in structure. There's only one field / one column, which I name TERM, and later use as ${TERM} I don't really need full CSV because it's only one string per line. There's no commas or quotes. When I run the Unix "file" command on the file, it says UTF-8 text. I've also verified it in command line and graphical mode on two machines. JMeter CSV Dataset Config: Filename: japanese-searches.csv File encoding: UTF-8 (also tried without) Variable names: TERM Delimiter: , Allow Quoted Data: False (I also tried True, different, but still wrong) Recycle at EOF: True Stop at EOF: False Staring mode: All threads A few things I've tried: Tried Allow quoted Data. It changed to other strange characters. -Dfile.encoding=UTF-8 Tried encoding the POST, but it just turned into a bunch of %nn for question marks And I'm not sure how "debug" just after the each line of the CSV is read in. I think it's corrupted right away, but I'm not sure. If it's only mangled when I reference it, then instead of ${TERM} perhaps there's some other "to bytes" function call. I'll start checking into that. I haven't done anything with the JMeter functions yet.

  • Flexible forms and supporting database structure

    - by sunwukung
    I have been tasked with creating an application that allows administrators to alter the content of the user input form (i.e. add arbitrary fields) - the contents of which get stored in a database. Think Modx/Wordpress/Expression Engine template variables. The approach I've been looking at is implementing concrete tables where the specification is consistent (i.e. user profiles, user content etc) and some generic field data tables (i.e. text, boolean) to store non-specific values. Forms (and model fields) would be generated by first querying the tables and retrieving the relevant columns - although I've yet to think about how I would setup validation. I've taken a look at this problem, and it seems to be indicating an EAV type approach - which, from my brief research - looks like it could be a greater burden than the blessings it's flexibility would bring. I've read a couple of posts here, however, which suggest this is a dangerous route: How to design a generic database whose layout may change over time? Dynamic Database Schema I'd appreciate some advice on this matter if anyone has some to give regards SWK

  • Bind a ViewModel to a DropDownListFor with a third value besides dataValueField/dataTextField

    - by Elisa
    When I show a list of testplanViewModels in my View and the user selects one the SelectedTestplanId is returned to the Controller post action. What should also be returned is the TemplateId which belongs to the SelectedTestplanId. When the AutoMapper definition is run the Testplan.TestplanId is implicitly copied over to the TestplanViewModel.TestplanId. The same could be done by providing a TemplateId on the TestplanViewModel. When the user selects now a "TestplanViewModel" in the View, how can I attach the TemplateId to the controller action to access it there? The DropDownList does not allow 2 dataValueFields! CreateMap<Testplan, TestplanViewModel>().ForMember(dest => dest.Name, opt => opt.MapFrom(src => string.Format("{0}-{1}-{2}-{3}", src.Release.Name, src.Template.Name, src.CreatedAt, src.CreatedBy))); public ActionResult OpenTestplanViewModels() { IEnumerable<Testplan> testplans = _testplanDataProvider.GetTestplans(); var viewModel = new OpenTestplanViewModel { DisplayList = Mapper.Map<IEnumerable<Testplan>, IEnumerable<TestplanViewModel>>(testplans) }; return PartialView(viewModel); } public class TestplanViewModel { public int TestplanId { get; set; } public string Name { get; set; } } public class OpenTestplanViewModel { [Required(ErrorMessage = "No item selected.")] public int SelectedTestplanId { get; set; } public IEnumerable<TestplanViewModel> DisplayList { get; set; } } OpenTestplanViewModel @using (Html.BeginForm("Open", "Testplan")) { @Html.ValidationSummary(false) @Html.DropDownListFor(x => x.SelectedTestplanId, new SelectList(Model.DisplayList, "TestplanId", "Name"), new { @class = "listviewmodel" }) }

  • ASP.NET MVC Unit Testing Controllers - Repositories

    - by Brian McCord
    This is more of an opinion seeking question, so there may not be a "right" answer, but I would welcome arguments as to why your answer is the "right" one. Given an MVC application that is using Entity Framework for the persistence engine, a repository layer, a service layer that basically defers to the repository, and a delete method on a controller that looks like this: public ActionResult Delete(State model) { try { if( model == null ) { return View( model ); } _stateService.Delete( model ); return RedirectToAction("Index"); } catch { return View( model ); } } I am looking for the proper way to Unit Test this. Currently, I have a fake repository that gets used in the service, and my unit test looks like this: [TestMethod] public void Delete_Post_Passes_With_State_4() { //Arrange var stateService = GetService(); var stateController = new StateController( stateService ); ViewResult result = stateController.Delete( 4 ) as ViewResult; var model = (State)result.ViewData.Model; //Act RedirectToRouteResult redirectResult = stateController.Delete( model ) as RedirectToRouteResult; stateController = new StateController( stateService ); var newresult = stateController.Delete( 4 ) as ViewResult; var newmodel = (State)newresult.ViewData.Model; //Assert Assert.AreEqual( redirectResult.RouteValues["action"], "Index" ); Assert.IsNull( newmodel ); } Is this overkill? Do I need to check to see if the record actually got deleted (as I already have Service and Repository tests that verify this)? Should I even use a fake repository here or would it make more sense just to mock the whole thing? The examples I'm looking at used this model of doing things, and I just copied it, but I'm really open to doing things in a "best practices" way. Thanks.

  • Why is PHP discriminating between .php and .abc extensions for caching?

    - by Sam
    There seems to be a problem between how PHP engine handles identical files that differ only in their file extension. Problem: "An If-Modified-Since conditional request returned the full content unchanged." Also, I measured that the .php extension loads much faster than identitcal twin with .xxx extension even though the file contents are identical, and they differ only in their file extension. "HTTP allows clients to make conditional requests to see if a copy that they hold is still valid. Since this response has a Last-Modified header, clients should be able to use an If-Modified-Since request header for validation. RED has done this and found that the resource sends a full response even though it hadn't changed, indicating that it doesn't support Last-Modified validation." homepage ending with .php exact same file, but ending .ast Given: A home.php file is copied as home.xxx and this extension is added to htaccess to recognize it as a PHP file. The .php file listen to the php.ini where freshness is set to 3 hrs, the non .php files have to listen to htaccess where freshness is set to 2 hrs according to: AddType application/x-httpd-php .php .ast .abc .xxx .etc <IfModule mod_headers.c> ExpiresActive On ExpiresDefault M2419200 Header unset ETag FileETag None Header unset Pragma Header set Cache-Control "max-age=2419200" ##### DYNAMIC PAGES <FilesMatch "\\.(ast|php|abc|xxx)$"> ExpiresDefault M7200 Header set Cache-Control "public, max-age=7200" </FilesMatch> </IfModule> So far so good and everything loads, except, the non-php file doesn't cache properly, or it does cache well but doesn't validate well, to be more specific. See images enclosed. Only the non-php file extension causes the error and loads slower. The entire page.php loads faster as somehow all the elements in there then load properly from cache, while the page.abc has the full request returned while it ought to be cached, meaning the entire page is slower. Bottom line: What should be changed, in order eliminate the If-Modified-Since conditional request returning the full content unchanged?

  • Which are the RDBMS that minimize the server roundtrips? Which RDBMS are better (in this area) than

    - by user193655
    When the latency is high ("when pinging the server takes time") the server roundtrips make the difference. Now I don't want to focus on the roundtrips created in programming, but the roundtrips that occur "under the hood" in the DB engine, so the roundtrips that are 100% dependant on how the RDBMS is written itself. I have been told that FireBird has more roundtrips than MySQL. But this is the only information I know. I am currently supporting MS SQL but I'd like to change RDBMS (because I use Express Editions and in my scenario they are quite limiting from the performance point of view), so to make a wise choice I would like to include also this point into "my RDBMS comparison feature matrix" to understand which is the best RDBMS to choose as an alternative to MS SQL. So the bold sentence above would make me prefer MySQL to Firebird (for the roundtrips concept, not in general), but can anyone add informations? And MS SQL where is it located? Is someone able to "rank" the roundtrip performance of the main RDBMS, or at least: MS SQL, MySql, Postegresql, Firebird (I am not interested in Oracle since it is not free, and if I have to change I would change to a free RDBMS). Anyway MySql (as mentioned several times on stackoverflow) has a not clear future and a not 100% free license. So my final choice will probably dall on PostgreSQL or Firebird. Additional info: somehow you can answer my question by making a simple list like: MSSQL:3; MySQL:1; Firebird:2; Postgresql:2 (where 1 is good, 2 average, 3 bad). Of course if you can post some links where the roundtrips per RDBMSs are compared it would be great

  • How to Resolve a Transformation Service with BRE that occurs after an Orchestration in an Itinerary?

    - by Maxime Labelle
    In trying to implement simple integration patterns with Biztalk ESB Toolkit 2.0, I'm facing a problem trying to resolve a Transformation Itinerary Service that occurs after an Orchestration. I'm using the BRE Resolver to execute rules that need to inspect the Context Message Type property to determine the appropriate map to use. However, once the message reaches the step in the Itinerary associated with the Transformation Service, the map fails to execute. From careful investigation, it appears that the message type is not supplied to the "Resolution" object that is used internally by the BRE resolver. Indeed, since the message leaving the preceding Orchestration is typed System.Xml.XmlDocument, the type of the message is "demoted" from the context. By tracking rules engine execution, I can observe that the type of the message is indeed lost when reaching the BRE resolver. The type of the message is empty, whereas the strongly-typed of the document is Microsoft.XLANGs.BaseTypes.Any. The Orchestration service that I use is taken straight from the samples that ship with ESB Toolkit 2.0. Is there a way to perform Context-Based BRE resolution after an Orchestration in an Itinerary?

  • build an API service in Django

    - by Peter
    Hi all, I want to build an API service using Django. A basic workflow goes like this: First, an http request goes to http://mycompany.com/create.py?id=001&callback=http://callback.com. It will create a folder on the server with name 001. Second, if the folder does not exist, it will be created. You get response immediately in XML format. It will look like: <?xml version="1.0" encoding="UTF-8"?> <response> <status> <statusCode>0</statusCode> <message>Success</message> </status> <group id="001"/> </response> Finally, the server will do its job (i.e. creating the folder). After it is done, the server does a callback to the URL provided. Currently, I use return render_to_response('create.xml', {'statusCode': statusCode, 'statusMessage': statusMessage, 'groupId': groupId, }, mimetype = 'text/xml') to send the XML response back. I have an XML template which has statusCode, statusMessage, groupId placeholders. <?xml version="1.0" encoding="UTF-8"?> <response> <status> <statusCode>{{ statusCode }}</statusCode> <message>{{ statusMessage }}</message> </status> {% if not statusCode %} <group id="{{ groupId }}"/> {% endif %} </response> But in this way I have to put step 3 before step 2, because otherwise step 3 will not be executed if it is after return statement. Can somebody give me some suggestions how to do this? Thanks.

  • Set ContentTemplate in CodeBehind: XamlParseException 2260 Error

    - by user362215
    Hi, I'd like to change the ContentTemplate of a ContentPresenter in the CodeBehind file. But if I run the Silverlight 4 application a XamlParseException with the error code 2260 occures. foreach (ContentPresenter item in Headers) { item.ContentTemplate = Parent.UnselectedHeaderTemplate; } if ((index >= 0) && (index < Headers.Count)) { ContentPresenter item0 = (ContentPresenter)Headers[index]; item0.ContentTemplate = Parent.SelectedHeaderTemplate; } If I do only the foreach code without the code in the "if", it works. And if I only do the code in the "if" without the foreach it works too. But togheter (the "if"-code and the foreach-code) it doesn't work. I have no idea why it doesn't work. The two templates look like this: <Setter Property="UnselectedHeaderTemplate"> <Setter.Value> <DataTemplate> <ContentControl Content="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=Content}" Margin="10,-10" FontSize="72" Foreground="#FF999999" CacheMode="BitmapCache"/> </DataTemplate> </Setter.Value> </Setter> <!-- SelectedHeader template --> <Setter Property="SelectedHeaderTemplate"> <Setter.Value> <DataTemplate> <ContentControl Content="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=Content}" Margin="10,-10" FontSize="72" Foreground="{TemplateBinding Foreground}" CacheMode="BitmapCache"/> </DataTemplate> </Setter.Value> </Setter> If you have an idea what problem is please tell me.
