31,644,740 | 0 | <p>I think you should optimise your adapter for recycler view. PagerAdapter is not the culprit. It would be Recycler View that is involved in scrolling.</p> <p>Ideally you should use bean classes instead of ArrayList> because it takes more time to compute has code on keys every time. Also you should take care of following things.</p> <p>Also you are calling <code>arrayList.get(position)</code> every time you want to get some data, call it single time and make the reference of it in bindView and use that reference every where.</p> <p>Make your view hierarchy as flatten as possible, because view hierarchy matters a lot in AdapterViews and can have impact on performance depending upon nesting level.</p> |

21,782,032 | 0 | <p>Based on my understanding, <strong>Navigation</strong> with <strong>ScopedRegions</strong> would not be a straight forward feature of <strong>Prism</strong>. There are some workarounds posted however, in order to accomplish it in a quite simple way.</p> <p>You can look at the following post and discussion thread for handling <strong>ScopeRegionManagers</strong> across <strong>Navigation</strong>:</p> <ul> <li><a href="http://blogs.southworks.net/aadami/2011/11/30/prism-region-navigation-and-scoped-regions/" rel="nofollow">Prism Region Navigation and Scoped Regions</a></li> <li><a href="https://compositewpf.codeplex.com/discussions/236849" rel="nofollow">Navigation and ScopedRegions</a></li> </ul> <p>Basically, Agustin Adami's proposal would be to obtain the scoped <strong>RegionManager</strong> from the <strong><em>Region.Add()</em></strong> method, through the <strong>NavigationResult</strong> passed in the navigation callback from the <strong><em>RequestNavigate()</em></strong> method.</p> <p>The Navigation call then would look as follows:</p> <pre><code>this.regionManager.RequestNavigate( "MainRegion", new Uri("HelloWorldView?createRegionManagerScope=true", UriKind.Relative), (result) => { var myRegionManager = result.ExtractRegionManager(); myRegionManager.RequestNavigate("NestedRegion", new Uri("View1", UriKind.Relative)); }); </code></pre> <hr> <p><strong>UPDATE:</strong></p> <p>One possible approach for setting the scoped <strong>RegionManager</strong> into the child <strong>ViewModel</strong> would be by using a <strong>Shared Service</strong> and get the scoped <strong>RegionManager</strong> from there.</p> <p>The <strong>Main ViewModel</strong> would store the <strong>RegionManager</strong> as follows:</p> <pre><code>... bool createRegionManagerScope = true; var scopedRegionManager = region.Add(view, null, createRegionManagerScope); var dictionary = ServiceLocator.Current.GetInstance<ScopedRegionManagersSharedDictionary>(); dictionary[Names.ScopedRegionManagerName] = scopedRegionManager; this.regionManager.RequestNavigate( Names.MainRegion, new Uri("HelloWorldView", UriKind.Relative)); </code></pre> <p>And then, the child <strong>ViewModel</strong> should implement <strong>INavigationAware</strong> in order to retreive and set the scoped <strong>RegionManager</strong> on the <strong><em>OnNavigatedTo()</em></strong> method like shown below:</p> <pre><code>void OnNavigatedTo(NavigationContext navigationContext) { var dictionary = ServiceLocator.Current.GetInstance<ScopedRegionManagersSharedDictionary>(); this.regionManager = dictionary[Names.ScopedRegionManagerName]; ... } </code></pre> <p>I hope this helps, Regards.</p> |

I expect there will always be some element of "fade-in" due to the nature of the evolutionary process (though tweaking the evolutionary operators may affect how this looks).</p> <p>A pixel-by-pixel comparison can be expensive for anything but small images. For example, the 200x200 pixel image I use has 40,000 pixels. With three values per pixel (R, G and B), that's 120,000 values that have to be incorporated into the fitness calculation for a single image. In my implementation I scale the image down before doing the comparison so that there are fewer pixels. The trade-off is slightly reduced accuracy of the evolved image.</p> <p>In investigating alternative fitness functions I came across some suggestions to use the <a href="http://en.wikipedia.org/wiki/YUV" rel="nofollow noreferrer">YUV colour space</a> instead of RGB since this is more closely aligned with human perception.</p> <p>Another idea that I had was to compare only a randomly selected sample of pixels. I'm not sure how well this would work without trying it. Since the pixels compared would be different for each evaluation it would have the effect of maintaining diversity within the population.</p> <p>Beyond that, you are in the realms of computer vision. I expect that these techniques, which rely on feature extraction, would be more expensive per image, but they may be faster overall if they result in fewer generations being required to achieve an acceptable result.

8,534,840 | 0 | <p>After some experimentation, I have found a way to specify a custom skipper and will outline it here:</p> <pre><code>template<typename Iterator> struct pl0_skipper : public qi::grammar<Iterator> { pl0_skipper() : pl0_skipper::base_type(skip, "PL/0") { skip = ascii::space | ('{' >> *(qi::char_ - '}') >> '}'); } qi::rule<Iterator> skip; }; template<typename Iterator, typename Skipper = pl0_skipper<Iterator>> struct pl0_grammar : public qi::grammar<Iterator, Skipper> { /* The rules use our skipper */ qi::rule<Iterator, Skipper> start; qi::rule<Iterator, Skipper> block; qi::rule<Iterator, Skipper> statement; }; </code></pre> <p>The secret lies in the call of the parser. For some reason, when you want to parse this using <code>parse_phrase</code>, you have to give a skipper grammar object. I was not aware of this:</p> <pre><code>typedef std::string::const_iterator iterator_t; typedef parser::pl0_grammar<iterator_t> grammar; typedef parser::pl0_skipper<iterator_t> skipper; grammar g; skipper ws; iterator_t iter = str.begin(); iterator_t end = str.end(); bool r = phrase_parse(iter, end, g, ws); </code></pre> <p>This works.</p> |

13,826,975 | 0 | <p>Since you can't refactor as suggested, you should check what type you need to return based on the <code>type</code> member that you assign in the <code>init()</code> function. I assume this will work, but you haven't shown where <code>type</code> is defined:</p> <pre><code>const void* Investment::getItem() const { switch(type) { case BUILDING_TYPE: case UNIT_TYPE: return &unitType; case UPGRADE_TYPE: return &upgradeType; case TECH_TYPE: return &techType; } return NULL; } </code></pre> <p>Doing this however, means that the caller of <code>getItem()</code> has to be able to perform the appropriate downcast. Given that you don't provide this explicitly, this is going to be a constant source of confusion of users of your code.</p> <h1>However:</h1> <p>If you are passing around <code>void*</code> and expecting users of your class to downcast to the correct type, this is almost always an indication of bad design in <code>C++</code>. The correct approach would be to refactor this into a proper polymorphic class hierarchy as suggested by @juanchopanza in his answer.</p> |

21,392,529 | 0 | Cascading multi-value parameter issue in SSRS 2008 <p>Basically I have built a report using SSRS 2008, the report has cascading parameters, the independent one is a multi-value parameter (work units) populated with values from a database query, the dependent parameter (job positions contained in respective work units) also gets values from a query with a where clause as follows:</p> <pre><code>WHERE position.unitId IN (@units) </code></pre> <p>@units being the multi-value parameter. The default value for units is the query itself - all of which the user has access to. So upon opening the report, all available units are selected and all respective job positions are retrieved - works fine. But a aser can also have no access to any units, which makes the dependent query fail, cause no units were retrieved hence @units contains no values. I would have thought the query would not fire until @units has a value present.. anyways I have tried to check the contents of @units before querying for job positions in various ways:</p> <p>*replacing @units parameter with the following expression: =IIF(Parameters!units.Count = 0, "00000000-0000-0000-0000-000000000000", Parameters!units.Value)</p> <p>*having another parameter containing a comma seperated string of the @units values and checking if the lenght of that is greater than 0 before executing the dependent dataset, etc.</p> <p>But now, when I open up the report, the drop down list of job position is empty, disabled and remains so until the values of units are changed or the report is run. After that they refresh alright it seems. So my question is, what may be the cause of the control being disabled (units are retrieved, so why does an expression as a parameter value for job positions messes it up?) and how to deal with this the right way, can`t seem to find something really of the same nature online. </p> <p>Any help will be greatly appreciated.</p> |
