  • Blogger issue with custom background images on Chrome and Safari

    - by hdx
    This is weird, the site in question is blog.andrebatista.info and it is a hosted at blogger.com. I'm trying to make the blogger template look the same as the one in my main website, www.andrebatista.info. For some reason if I go directly to the blog address Chrome and Safari fail to display all of my background images... all of them. However if I first go to www.andrebatista.info first and then go to the blog it renders just fine ?¿ The way I'm customizing it is by adding a link to my main site's stylesheet at the very end of the head tag on the blogger template. That stylesheet is displayed below: *{ margin:0; padding:0; border:0; } html,body { background:#064169 url(http://www.andrebatista.info/images/main_gradient_slice.jpg) repeat-x; font-family: Arial, "MS Trebuchet", sans-serif; font-size:18px; } #main_wrapper{ margin: 0 auto; width:1024px; } #header{ background: url(http://www.andrebatista.info/images/header.jpg); height:133px; border:none; margin:0; } #menu_wrapper{ background: url(http://www.andrebatista.info/images/menu.jpg); height:34px; overflow:hidden; } #menu_wrapper .menu_item{ color:white; float: left; border: 1 px solid red; height: 34px; padding-top:10px; text-align:center; width:100px; } #menu_wrapper .first{ padding-left:240px; float:left; width:100px; } #menu_wrapper .active,#menu_wrapper .menu_item:hover{ background-color:white; color:Teal; cursor: pointer; } #content_area_wrapper{ background: url(http://www.andrebatista.info/images/body_bg_slice.jpg) repeat-y; } #content_area{ min-height:524px; background: url(http://www.andrebatista.info/images/main_content_top.jpg) repeat-x; } #main_banner{ background: url(http://www.andrebatista.info/images/main_banner.jpg) no-repeat center center; width:662px; height:338px; margin: 0 auto; } #main_banner div{ color:white; padding-left:47px; padding-right:164px; padding-top:105px; } #text_area{ overflow:hidden; width:662px; margin:0 auto; padding:14px; } #contentList{ padding:0 20px 20px 20px; } #text_area .left{ width:50%; float:left; } #text_area .left{ width:50%; float:right; } #footer2{ background: url(http://www.andrebatista.info/images/footer.jpg); height:62px; } #footer{ background: url(http://www.andrebatista.info/images/footer.jpg); height:62px; } Any ideas on what I could be missing?

  • How do I get through proxy server environments for non-standard services?

    - by Ripred
    I'm not real hip on exactly what role(s) today's proxy servers can play and I'm learning so go easy on me :-) I have a client/server system I have written using a homegrown protocol and need to enhance the client side to negotiate its way out of a proxy environment. I have an existing client and server system written in C and C++ for the speed and a small amount of MFC in the client to handle the user interface. I have written both the server and client side of the system on Windows (the people I work for are mainly web developers using Windows everything - not a choice) sticking to Berkeley Sockets as it were via wsock32 for efficiency. The clients connect to the server through a nonstandard port (even though using port 80 is an option to get out of some environments but the protocol that goes over it isn't HTTP). The TCP connection(s) stay open for the duration of the clients participation in real time conferences. Our customer base is expanding to all kinds of networked environments. I have been able to solve a lot of problems by adding the ability to connect securely over port 443 and using secure sockets which allows the protocol to pass through a lot environments since the internal packets can't be sniffed. But more and more of our customers are behind a proxy server environment and my direct connections don't make it through. My old school understanding of proxy servers is that they act as a proxy for external HTML content over HTTP, possibly locally caching popular material for faster local access, and also allowing their IT staff to blacklist certain destination sites. Customer are complaining that my software doesn't recognize and easily navigate its way through their proxy environments but I'm finding it difficult to decide what my "best fit" solution should be. My software doesn't tear down the connection after each client request, and on top of that packets can come from either side at any time, basically your typical custom client/server system for a specific niche. My first reaction is "why can't they just add my servers addresses to their white list" but if there is a programmatic way I can get through without requiring their IT staff to help it is politically better and arguably a better solution anyway. Plus maybe I'm still not understanding the role and purpose of what proxy servers and environments have grown to be these days. My first attempt at a solution was to use WinInet with its various proxy capabilities to establish a connection over port 80 to my non-standard protocol server (which knows enough to recognize and answer a simple HTTP-looking GET request and answer it with a simple HTTP response page to get around some environments that employ initial packet sniffing (DPI)). I retrieved the actual SOCKET handle behind WinInet's HINTERNET request object and had hoped to use that in place of my software's existing SOCKET connection and hopefully not need to change much more on the client side. It initially seemed to be my solution but on further inspection it seems that the OS gets first-chance at the received data on this socket since when I get notified of events via the standard select(...) statement on the socket and query the size of the data available via ioctlsocket the call succeeds but returns 0 bytes available, the reads don't work and it goes downhill from there. Can someone tell me of a client-side library (commercial is fine) will let me get past these proxy server environments with as little user and IT staff help as possible? From what I read it has grown past SOCKS and I figure someone has to have solved this problem before me. Thanks for reading my long-winded question, Ripred

  • C++ Compile problem when using Windows - CodeGear

    - by Carlos
    This is a follow-up question to this one i made earlier. Btw thanks Neil Butterworth for you help http://stackoverflow.com/questions/2461977/problem-compiling-c-in-codegear A quick recap. Im currently developing a C++ program for university, I used Netbeans 6.8 on my personal computer (Mac) and all works perfect. When I try them on my windows partition or at the university PC's using CodeGear RAD Studio 2009 & 2010 i was getting a few compile errors which were solved by adding the following header file: #include <string> However now the program does compile but it doesn't run, just a blank console. And am getting the following in the CodeGear event's log: Thread Start: Thread ID: 2024. Process Project1.exe (3280) Process Start: C:\Users\Carlos\Documents\RAD Studio\Projects\Debug\Project1.exe.

  • How to Force an Exception from a Task to be Observed in a Continuation Task?

    - by Richard
    I have a task to perform an HttpWebRequest using Task<WebResponse>.Factory.FromAsync(req.BeginGetRespone, req.EndGetResponse) which can obviously fail with a WebException. To the caller I want to return a Task<HttpResult> where HttpResult is a helper type to encapsulate the response (or not). In this case a 4xx or 5xx response is not an exception. Therefore I've attached two continuations to the request task. One with TaskContinuationOptions OnlyOnRanToCompletion and the other with OnlyOnOnFaulted. And then wrapped the whole thing in a Task<HttpResult> to pick up the one result whichever continuation completes. Each of the three child tasks (request plus two continuations) is created with the AttachedToParent option. But when the caller waits on the returned outer task, an AggregateException is thrown is the request failed. I want to, in the on faulted continuation, observe the WebException so the client code can just look at the result. Adding a Wait in the on fault continuation throws, but a try-catch around this doesn't help. Nor does looking at the Exception property (as section "Observing Exceptions By Using the Task.Exception Property" hints here). I could install a UnobservedTaskException event handler to filter, but as the event offers no direct link to the faulted task this will likely interact outside this part of the application and is a case of a sledgehammer to crack a nut. Given an instance of a faulted Task<T> is there any means of flagging it as "fault handled"? Simplified code: public static Task<HttpResult> Start(Uri url) { var webReq = BuildHttpWebRequest(url); var result = new HttpResult(); var taskOuter = Task<HttpResult>.Factory.StartNew(() => { var tRequest = Task<WebResponse>.Factory.FromAsync( webReq.BeginGetResponse, webReq.EndGetResponse, null, TaskCreationOptions.AttachedToParent); var tError = tRequest.ContinueWith<HttpResult>( t => HandleWebRequestError(t, result), TaskContinuationOptions.AttachedToParent |TaskContinuationOptions.OnlyOnFaulted); var tSuccess = tRequest.ContinueWith<HttpResult>( t => HandleWebRequestSuccess(t, result), TaskContinuationOptions.AttachedToParent |TaskContinuationOptions.OnlyOnRanToCompletion); return result; }); return taskOuter; } with: private static HttpDownloaderResult HandleWebRequestError( Task<WebResponse> respTask, HttpResult result) { Debug.Assert(respTask.Status == TaskStatus.Faulted); Debug.Assert(respTask.Exception.InnerException is WebException); // Try and observe the fault: Doesn't help. try { respTask.Wait(); } catch (AggregateException e) { Log("HandleWebRequestError: waiting on antecedent task threw inner: " + e.InnerException.Message); } // ... populate result with details of the failure for the client ... return result; } (HandleWebRequestSuccess will eventually spin off further tasks to get the content of the response...) The client should be able to wait on the task and then look at its result, without it throwing due to a fault that is expected and already handled.

  • Cannot create Desktop shortcut

  • How do I get jqGrid to work using ASP.NET + JSON on the backend?

    - by briandus
    Hi friends, ok, I'm back. I totally simplified my problem to just three simple fields and I'm still stuck on the same line using the addJSONData method. I've been stuck on this for days and no matter how I rework the ajax call, the json string, blah blah blah...I can NOT get this to work! I can't even get it to work as a function when adding one row of data manually. Can anyone PLEASE post a working sample of jqGrid that works with ASP.NET and JSON? Would you please include 2-3 fields (string, integer and date preferably?) I would be happy to see a working sample of jqGrid and just the manual addition of a JSON object using the addJSONData method. Thanks SO MUCH!! If I ever get this working, I will post a full code sample for all the other posting for help from ASP.NET, JSON users stuck on this as well. Again. THANKS!! tbl.addJSONData(objGridData); //err: tbl.addJSONData is not a function!! Here is what Firebug is showing when I receive this message: • objGridData Object total=1 page=1 records=5 rows=[5] ?

  • Coldfusion "Routines cannot be declared more than once"

    - by Nicholas
    We have the following code in our Application.cfc: <cffunction name="onError" returnType="void" output="false"> <cfargument name="exception" required="true"> <cfargument name="eventname" type="string" required="true"> <cfset cfcatch = exception> <cfinclude template="standalone/errors/error.cfm"> </cffunction> Within the error.cfm page we have this code (I didn't write it): <cfscript> function GetCurrentURL() { var theURL = "http"; if (cgi.https EQ "on" ) theURL = "#TheURL#s"; theURL = theURL & "://#cgi.server_name#"; if(cgi.server_port neq 80) theURL = theURL & ":#cgi.server_port#"; theURL = theURL & "#cgi.path_info#"; if(len(cgi.query_string)) theURL = theURL & "?#cgi.query_string#"; return theURL; } </cfscript> This is all part of a script that puts together bunches of details about the error and records it to the database. When an error occurs, we receive the message "The routine GetCurrentURL has been declared twice in different templates." However, I have searched the entire codebase in several different ways and found "GetCurrentURL" used only twice, both times in error.cfm. The first time is the declaration, and the second is actual use. So I'm not sure why CF is saying "in different templates". My next thought was that the problem is a recursive call, and that error.cfm is erroring and calling itself, so I attempted these two changes, either of which should have resolved the issue and unmasked the real error: <cfif StructKeyExists(variables,"GetCurrentURL") IS "NO"> <cfscript> function GetCurrentURL() { var theURL = "http"; if (cgi.https EQ "on" ) theURL = "#TheURL#s"; theURL = theURL & "://#cgi.server_name#"; if(cgi.server_port neq 80) theURL = theURL & ":#cgi.server_port#"; theURL = theURL & "#cgi.path_info#"; if(len(cgi.query_string)) theURL = theURL & "?#cgi.query_string#"; return theURL; } </cfscript> </cfif> And: <cfscript> if (!StructKeyExists(variables,"GetCurrentURL")) { function GetCurrentURL() { var theURL = "http"; if (cgi.https EQ "on" ) theURL = "#TheURL#s"; theURL = theURL & "://#cgi.server_name#"; if(cgi.server_port neq 80) theURL = theURL & ":#cgi.server_port#"; theURL = theURL & "#cgi.path_info#"; if(len(cgi.query_string)) theURL = theURL & "?#cgi.query_string#"; return theURL; } } </cfscript> Neither worked. I also tried adding this to the page just before the function call: <cfoutput>"#StructKeyExists(variables,"GetCurrentURL")#"</cfoutput> It caused the word "YES" to be printed on screen. This indicates that the above should work, as clearly the contents of the if statement will evaluate to "YES", and thus the if statement will evaluate to false, and thus the function will not be declared, and thus I will retain my sanity. But for some reason this problem persists. Any thoughts on what might be occuring or how to troubleshoot next? I'm stuck at this point.

  • Vertical text inside table headers using a JavaScript-based SVG library

    - by Oleg
    I use jqGrid with many columns containing boolean information, which are displayed as checkboxes inside the table (see http://www.ok-soft-gmbh.com/VerticalHeaders/TestFixedO.htm as an example). To display information more compactly I use vertical column headers. It works very well and works in jqGrid in all browsers (see my discussion with Tony Tomov in jqGrid forum http://www.trirand.com/blog/?page_id=393/feature-request/headers-with-vertical-orientation/), but in IE vertical text is blurred and doesn't look nice enough (open the link above in IE and you will see exactly what I mean). I was asked from users why the text displayed so strangely. So I'm thinking of using a JavaScript-based SVG library like SVG Web ( http://code.google.com/p/svgweb/ ) or Raphaël ( http://raphaeljs.com/ ). SVG is very powerful and it is difficult to find a good example. I need only to display vertical text (-90 grad, from the bottom up) and use if possible without working in mode of absolute positioning. So one more time my question: I need to have a possibility to display vertical text (-90 grad rotation) inside <td> elements of a table header. I want to use a JavaScript-based SVG library like SVG Web or Raphaël. The solution must support IE6. Does anybody have a good reference example which could help me do this? If somebody posts a whole solution of the problem I would be happy. To be exact here is my current solution: I define .rotate { -webkit-transform: rotate(-90deg); /* Safari 3.1+, Chrome */ -moz-transform: rotate(-90deg); /* Firefox 3.5+ */ -o-transform: rotate(-90deg); /* Opera starting with 10.50 */ /* Internet Explorer: */ filter: progid:DXImageTransform.Microsoft.BasicImage(rotation=3); /* IE6, IE7 */ -ms-filter: "progid:DXImageTransform.Microsoft.BasicImage(rotation=3)" /* IE8 */; } define RotateCheckboxColumnHeaders function var RotateCheckboxColumnHeaders = function (grid, headerHeight) { // we use grid as context (if one have more as one table on tnhe page) var trHead = $("thead:first tr", grid.hdiv); var cm = grid.getGridParam("colModel"); $("thead:first tr th").height(headerHeight); headerHeight = $("thead:first tr th").height(); for (var iCol = 0; iCol < cm.length; iCol++) { var cmi = cm[iCol]; if (cmi.formatter === 'checkbox') { // we must set width of column header div BEFOR adding class "rotate" to // prevent text cutting based on the current column width var headDiv = $("th:eq(" + iCol + ") div", trHead); headDiv.width(headerHeight).addClass("rotate"); if (!$.browser.msie) { if ($.browser.mozilla) { headDiv.css("left", (cmi.width - headerHeight) / 2 + 3).css("bottom", 7); } else { headDiv.css("left", (cmi.width - headerHeight) / 2); } } else { var ieVer = jQuery.browser.version.substr(0, 3); // Internet Explorer if (ieVer !== "6.0" && ieVer !== "7.0") { headDiv.css("left", cmi.width / 2 - 4).css("bottom", headerHeight / 2); $("span", headDiv).css("left", 0); } else { headDiv.css("left", 3); } } } } }; And include a call like RotateCheckboxColumnHeaders(grid, 110); after creating jqGrid.

  • WPF items not visible when grouping is applied

    - by Tri Q
    Hi, I'm having this strange issue with my ItemsControl grouping. I have the following setup: <ItemsControl Margin="3" ItemsSource="{Binding Communications.View}" > <ItemsControl.GroupStyle> <GroupStyle> <GroupStyle.ContainerStyle> <Style TargetType="{x:Type GroupItem}"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type GroupItem}"> <Expander> <Expander.Header> <Grid> <Grid.ColumnDefinitions > <ColumnDefinition Width="*" /> <ColumnDefinition Width="Auto" /> </Grid.ColumnDefinitions> <TextBlock Text="{Binding ItemCount, StringFormat='{}[{0}] '}" FontWeight="Bold" /> <TextBlock Grid.Column="1" Text="{Binding Name, Converter={StaticResource GroupingFormatter}, StringFormat='{}Subject: {0}'}" FontWeight="Bold" /> </Grid> </Expander.Header> <ItemsPresenter /> </Expander> </ControlTemplate> </Setter.Value> </Setter> </Style> </GroupStyle.ContainerStyle> </GroupStyle> </ItemsControl.GroupStyle> <ItemsControl.ItemTemplate> <DataTemplate> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width="Auto" /> <ColumnDefinition Width="*" /> <ColumnDefinition Width="Auto" /> </Grid.ColumnDefinitions> <Grid.RowDefinitions> <RowDefinition /> <RowDefinition /> </Grid.RowDefinitions> <TextBlock FontWeight="Bold" Text="{Binding Inspector, Converter={StaticResource NameFormatter}, StringFormat='{}From {0}:'}" Margin="3" /> <TextBlock Text="{Binding SentDate, StringFormat='{}{0:dd/MM/yy}'}" Grid.Row="1" Margin="3"/> <TextBlock Text="{Binding Message }" Grid.Column="1" Grid.RowSpan="2" Margin="3"/> <Button Command="vm:CommunicationViewModel.DeleteMessageCommand" CommandParameter="{Binding}" HorizontalAlignment="Right" Grid.Column="2">Delete</Button> </Grid> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> In my ViewModel, I expose a CollectionViewSource named 'Communications'. I proceed to adding a grouping patter like so: Communications.GroupDescriptions.Add(new PropertyGroupDescription("Subject")); Now, the problem i'm experience is the grouping work fine, but I can't see any items inside the groups. What am I doing wrong? Any pointers would be much appreciated.

  • Symfony2: validate an object that is not an entity

    - by Marronsuisse
    I am using CraueFormFlowBundle to have a multiple page form, and am trying to do some validation on some of the fields but can't figure out how to do this. The object that needs to be validated isn't an Entity, which is causing me trouble. I tried adding a collectionConstraint in the getDefaultOption function of my form type class, but this doesn't work as I get the "Expected argument of type array or Traversable and ArrayAccess" error. I tried with annotations in my object class, but they don't seem to be taken into account. Are annotations taken into account if the class isn't an entity? (i set enable_annotations to true) Anyway, what is the proper way to do this? Basically, I just want to validate that "age" is an integer... class PoemDataCollectorFormType extends AbstractType { public function buildForm(FormBuilder $builder, array $options) { switch ($options['flowStep']) { case 6: $builder->add('msgCategory', 'hidden', array( )); $builder->add('msgFIB','text', array( 'required' => false, )); $builder->add('age', 'integer', array( 'required' => false, )); break; } } public function getDefaultOptions(array $options) { $options = parent::getDefaultOptions($options); $options['flowStep'] = 1; $options['data_class'] = 'YOP\YourOwnPoetBundle\PoemBuilder\PoemDataCollector'; $options['intention'] = 'my_secret_key'; return $options; } } EDIT: add code, handle validation with annotations As Cyprian, I was pretty sure that using annotations should work, however it doesn't... Here is how I try: In my Controller: public function collectPoemDataAction() { $collector = $this->get('yop.poem.datacollector'); $flow = $this->get('yop.form.flow.poemDataCollector'); $flow->bind($collector); $form = $flow->createForm($collector); if ($flow->isValid($form)) { .... } } In my PoemDataCollector class, which is my data class (service yop.poem.datacollector): class PoemDataCollector { /** * @Assert\Type(type="integer", message="Age should be a number") */ private $age; } EDIT2: Here is the services implementation: The data class (PoemDataCollector) seems to be linked to the flow class and not to the form.. Is that why there is no validation? <service id="yop.poem.datacollector" class="YOP\YourOwnPoetBundle\PoemBuilder\PoemDataCollector"> </service> <service id="yop.form.poemDataCollector" class="YOP\YourOwnPoetBundle\Form\Type\PoemDataCollectorFormType"> <tag name="form.type" alias="poemDataCollector" /> </service> <service id="yop.form.flow.poemDataCollector" class="YOP\YourOwnPoetBundle\Form\PoemDataCollectorFlow" parent="craue.form.flow" scope="request"> <call method="setFormType"> <argument type="service" id="yop.form.poemDataCollector" /> </call> </service> How can I do the validation while respecting the craueFormFlowBundle guidelines? The guidelines state: Validation groups To validate the form data class a step-based validation group is passed to the form type. By default, if getName() of the form type returns registerUser, such a group is named flow_registerUser_step1 for the first step. Where should I state my constraint to use those validation groups..? I tried: YOP\YourOwnPoetBundle\PoemBuilder\Form\Type\PoemDataCollectorFormType: properties: name: - MinLength: { limit: 5, message: "Your name must have at least {{ limit }} characters.", groups: [flow_poemDataCollector_step1] } sex: - Type: type: integer message: Please input a number groups: [flow_poemDataCollector_step6] But it is not taken into acount.

  • Choosing a type for search results in C#

    - by Chris M
    I have a result set that will never exceed 500; the results that come back from the web-service are assigned to a search results object. The data from the webservice is about 2mb; the bit I want to use is about a third of each record, so this allows me to cache and quickly manipulate it. I want to be able to sort and filter the results with the least amount of overhead and as fast as possible so I used the VCSKICKS timing class to measure their performance Average Total (10,000) Type Create Sort Create Sort HashSet 0.1579 0.0003 1579 3 IList 0.0633 0.0002 633 2 IQueryable 0.0072 0.0432 72 432 Measured in Seconds using http://www.vcskicks.com/algorithm-performance.php I created the hashset through a for loop over the web-service response (adding to the hashset). The List & IQueryable were created using LINQ. Question I can understand why HashSet takes longer to create (the foreach loop vs linq); but why would IQueryable take longer to sort than the other two; and finally is there a better way to assign the HashSet. Thanks Actual Program public class Program { private static AuthenticationHeader _authHeader; private static OPSoapClient _opSession; private static AccommodationSearchResponse _searchResults; private static HashSet<SearchResults> _myHash; private static IList<SearchResults> _myList; private static IQueryable<SearchResults> _myIQuery; static void Main(string[] args) { #region Setup WebService _authHeader = new AuthenticationHeader { UserName = "xx", Password = "xx" }; _opSession = new OPSoapClient(); #region Setup Search Results _searchResults = _opgSession.SearchCR(_authHeader, "ENG", "GBP", "GBR"); #endregion Setup Search Results #endregion Setup WebService // HASHSET SpeedTester hashTest = new SpeedTester(TestHashSet); hashTest.RunTest(); Console.WriteLine("- Hash Test \nAverage Running Time: {0}; Total Time: {1}", hashTest.AverageRunningTime, hashTest.TotalRunningTime); SpeedTester hashSortTest = new SpeedTester(TestSortingHashSet); hashSortTest.RunTest(); Console.WriteLine("- Hash Sort Test \nAverage Running Time: {0}; Total Time: {1}", hashSortTest.AverageRunningTime, hashSortTest.TotalRunningTime); // ILIST SpeedTester listTest = new SpeedTester(TestList); listTest.RunTest(); Console.WriteLine("- List Test \nAverage Running Time: {0}; Total Time: {1}", listTest.AverageRunningTime, listTest.TotalRunningTime); SpeedTester listSortTest = new SpeedTester(TestSortingList); listSortTest.RunTest(); Console.WriteLine("- List Sort Test \nAverage Running Time: {0}; Total Time: {1}", listSortTest.AverageRunningTime, listSortTest.TotalRunningTime); // IQUERIABLE SpeedTester iqueryTest = new SpeedTester(TestIQueriable); iqueryTest.RunTest(); Console.WriteLine("- iquery Test \nAverage Running Time: {0}; Total Time: {1}", iqueryTest.AverageRunningTime, iqueryTest.TotalRunningTime); SpeedTester iquerySortTest = new SpeedTester(TestSortableIQueriable); iquerySortTest.RunTest(); Console.WriteLine("- iquery Sort Test \nAverage Running Time: {0}; Total Time: {1}", iquerySortTest.AverageRunningTime, iquerySortTest.TotalRunningTime); } static void TestHashSet() { var test = _searchResults.Items; _myHash = new HashSet<SearchResults>(); foreach(var x in test) { _myHash.Add(new SearchResults { Ref = x.Ref, Price = x.StandardPrice }); } } static void TestSortingHashSet() { var sorted = _myHash.OrderBy(s => s.Price); } static void TestList() { var test = _searchResults.Items; _myList = (from x in test select new SearchResults { Ref = x.Ref, Price = x.StandardPrice }).ToList(); } static void TestSortingList() { var sorted = _myList.OrderBy(s => s.Price); } static void TestIQueriable() { var test = _searchResults.Items; _myIQuery = (from x in test select new SearchResults { Ref = x.Ref, Price = x.StandardPrice }).AsQueryable(); } static void TestSortableIQueriable() { var sorted = _myIQuery.OrderBy(s => s.Price); } }

  • How to notify client about updated UpdatePanel content on server side

    - by csh1981
    I have a problem with UpdatePanel.Update() which works initially but then stops. I have tumbled with this problem for some time and some background is needed so please read ahead. I have an ASP.net application in which I have a subpage that display computed information in graphs. Each graph is embedded in an UpdatePanel. The graph is a user control that uses the standard asp:Chart for display. My task is to enable this page with AJAX capabilities so the page is responsive during postbacks. When I access this page from another page, during the initial page rendering, I use a wait dialog for each graph and a pageload event on the client side. In the client event, a hidden button is clicked which a server event handles (the hidden button is inside an UpdatePanel so the postback is asynchronous). Each graph is computed and the UpdatePanels are in turn updated with the Chart content. This is done using UpdatePanel.Update. And it is successful. However, I also have some RadioButtons on the page. These are dynamically created. The purpose of them is to switch graph type --- to show the same data in a different way. Same type of time consuming computation is needed in order to do so. I subscribe on each RadioButton's OnCheckedChanged event and the postback is asynchronous since the radiobuttons are inside an UpdatePanel. In the server event handler I determine the type of graph and use this as an input to the Chart control. I then remove the old Chart control from my Panel and adds new Chart and then I call UpdatePanel.Update(). But with no success. Nothing happens, no errors, nothing. Why is this?? I think this is strange because if I compute every Chart data in the initial rendering instead of using the "Wait dialog"-solution described earlier then I can select graph types successfully and all subsequent AJAX requests work as intended. Also, the same code (computing the chart, removal, and adding the Chart control to Panel and UpdatePanel.Update()) is hit during the initial rendering of the page, and it works only the first time. Here is the method that computes the graph and adds it to the panel and update the UpdatePanel: public void UpdateGraph(GraphType type, GraphMapper mapper) { //Panel is the content of UpdatePanelGraph's Panel.Controls.Clear(); chart = new Chart(type, mapper); //Computation happens inside here panel.Controls.Add(chart); //UpdatePanelGraph is in UpdateMode Conditional and has //ChildrenAsTriggers set to false UpdatePanelGraph.Update(); } I really need a way for these radiobuttons to work, possible using some clientside JavaScript or another way of handling things on the server side. I have thought about using a JavaScript postback call on the UpdatePanel instead of the UpdatePanel.Update(). However, the issue I have here is how to notify the client side when the server side is finished with computing the graph? An plausible explanation of the strange behavior is also much appreciated. Any help appreciated, thanks

  • What am I doing wrong with this use of StructLayout( LayoutKind.Explicit ) when calling a PInvoke st

    - by csharptest.net
    The following is a complete program. It works fine as long as you don't uncomment the '#define BROKEN' at the top. The break is due to a PInvoke failing to marshal a union correctly. The INPUT_RECORD structure in question has a number of substructures that might be used depending on the value in EventType. What I don't understand is that when I define only the single child structure of KEY_EVENT_RECORD it works with the explicit declaration at offset 4. But when I add the other structures at the same offset the structure's content get's totally hosed. //UNCOMMENT THIS LINE TO BREAK IT: //#define BROKEN using System; using System.Runtime.InteropServices; class ConIOBroken { static void Main() { int nRead = 0; IntPtr handle = GetStdHandle(-10 /*STD_INPUT_HANDLE*/); Console.Write("Press the letter: 'a': "); INPUT_RECORD record = new INPUT_RECORD(); do { ReadConsoleInputW(handle, ref record, 1, ref nRead); } while (record.EventType != 0x0001/*KEY_EVENT*/); Assert.AreEqual((short)0x0001, record.EventType); Assert.AreEqual(true, record.KeyEvent.bKeyDown); Assert.AreEqual(0x00000000, record.KeyEvent.dwControlKeyState & ~0x00000020);//strip num-lock and test Assert.AreEqual('a', record.KeyEvent.UnicodeChar); Assert.AreEqual((short)0x0001, record.KeyEvent.wRepeatCount); Assert.AreEqual((short)0x0041, record.KeyEvent.wVirtualKeyCode); Assert.AreEqual((short)0x001e, record.KeyEvent.wVirtualScanCode); } static class Assert { public static void AreEqual(object x, object y) { if (!x.Equals(y)) throw new ApplicationException(); } } [DllImport("Kernel32.dll", CharSet = CharSet.Unicode, SetLastError = true)] public static extern IntPtr GetStdHandle(int nStdHandle); [DllImport("Kernel32.dll", CharSet = CharSet.Unicode, SetLastError = true)] public static extern bool ReadConsoleInputW(IntPtr hConsoleInput, ref INPUT_RECORD lpBuffer, int nLength, ref int lpNumberOfEventsRead); [StructLayout(LayoutKind.Explicit)] public struct INPUT_RECORD { [FieldOffset(0)] public short EventType; //union { [FieldOffset(4)] public KEY_EVENT_RECORD KeyEvent; #if BROKEN [FieldOffset(4)] public MOUSE_EVENT_RECORD MouseEvent; [FieldOffset(4)] public WINDOW_BUFFER_SIZE_RECORD WindowBufferSizeEvent; [FieldOffset(4)] public MENU_EVENT_RECORD MenuEvent; [FieldOffset(4)] public FOCUS_EVENT_RECORD FocusEvent; //} #endif } [StructLayout(LayoutKind.Sequential)] public struct KEY_EVENT_RECORD { public bool bKeyDown; public short wRepeatCount; public short wVirtualKeyCode; public short wVirtualScanCode; public char UnicodeChar; public int dwControlKeyState; } [StructLayout(LayoutKind.Sequential)] public struct MOUSE_EVENT_RECORD { public COORD dwMousePosition; public int dwButtonState; public int dwControlKeyState; public int dwEventFlags; }; [StructLayout(LayoutKind.Sequential)] public struct WINDOW_BUFFER_SIZE_RECORD { public COORD dwSize; } [StructLayout(LayoutKind.Sequential)] public struct MENU_EVENT_RECORD { public int dwCommandId; } [StructLayout(LayoutKind.Sequential)] public struct FOCUS_EVENT_RECORD { public bool bSetFocus; } [StructLayout(LayoutKind.Sequential)] public struct COORD { public short X; public short Y; } } UPDATE: For those worried about the struct declarations themselves: bool is treated as a 32-bit value the reason for offset(4) on the data is to allow for the 32-bit structure alignment which prevents the union from beginning at offset 2. Again, my problem isn't making PInvoke work at all, it's trying to figure out why these additional structures (supposedly at the same offset) are fowling up the data by simply adding them.

  • RackSpace Cloud Strips $_SESSION if URL Has Certain File Extensions

    - by macinjosh
    The Situation I am creating a video training site for a client on the RackSpace Cloud using the traditional LAMP stack (RackSpace's cloud has both Windows and LAMP stacks). The videos and other media files I'm serving on this site need to be protected as my client charges money for access to them. There is no DRM or funny business like that, essentially we store the files outside of the web root and use PHP to authenticate user's before they are able to access the files by using mod_rewrite to run the request through PHP. So let's say the user requests a file at this URL: http://www.example.com/uploads/preview_image/29.jpg I am using mod_rewrite to rewrite that url to: http://www.example.com/files.php?path=%2Fuploads%2Fpreview_image%2F29.jpg Here is a simplified version of the files.php script: <?php // Setups the environment and sets $logged_in // This part requires $_SESSION require_once('../../includes/user_config.php'); if (!$logged_in) { // Redirect non-authenticated users header('Location: login.php'); } // This user is authenticated, continue $content_type = "image/jpeg"; // getAbsolutePathForRequestedResource() takes // a Query Parameter called path and uses DB // lookups and some string manipulation to get // an absolute path. This part doesn't have // any bearing on the problem at hand $file_path = getAbsolutePathForRequestedResource($_GET['path']); // At this point $file_path looks something like // this: "/path/to/a/place/outside/the/webroot" if (file_exists($file_path) && !is_dir($file_path)) { header("Content-Type: $content_type"); header('Content-Length: ' . filesize($file_path)); echo file_get_contents($file_path); } else { header('HTTP/1.0 404 Not Found'); header('Status: 404 Not Found'); echo '404 Not Found'; } exit(); ?> The Problem Let me start by saying this works perfectly for me. On local test machines it works like a charm. However once deployed to the cloud it stops working. After some debugging it turns out that if a request to the cloud has certain file extensions like .JPG, .PNG, or .SWF (i.e. extensions of typically static media files.) the request is routed to a cache system called Varnish. The end result of this routing is that by the time this whole process makes it to my PHP script the session is not present. If I change the extension in the URL to .PHP or if I even add a query parameter Varnish is bypassed and the PHP script can get the session. No problem right? I'll just add a meaningless query parameter to my requests! Here is the rub: The media files I am serving through this system are being requested through compiled SWF files that I have zero control over. They are generated by third-party software and I have no hope of adding or changing the URLs that they request. Are there any other options I have on this? Update: I should note that I have verified this behavior with RackSpace support and they have said there is nothing they can do about it.

  • How to populate the span tags for all text nodes between specific self closing tags.

    - by Rachel
    I want to populate span tags for all text nodes between the self closing tags s1 and s2 having the same id. Eg. For the input: <a> <b>Some <s1 id="1" />text here</b> <c>Some <s2 id="1"/>more text <s1 id="2"/> here<c/> <d>More data</d> <e>Some <s2 id="2" />more data</e> </a> In the above input i want to enclose every text node between <s1 id="1"/> and <s2 id="1" /> with span tags. Also all the text node between <s1 id="2" /> and <s2 id="2" /> Expected Output: <a> <b>Some <span class="spanClass" id="1a">text here</span></b> <c><span class="spanClass" id="1b">Some </span>more text <span class="spanClass" id="2a"> here</span></c> <d><span class="spanClass" id="2b">More data</span></d> <e><span class="spanClass" id="2c">Some </span>more data</e> </a> I am not concened about the pattern of the id tag populated for the span as along it is unique. If the transformation of the input to the output form requires the list of ids of the s1 , s2 tag pairs say 1, 2 etc i can assume that it in place in any form if required. Hope i am clear. How can this be achieved using XSL? EDIT: The input can have any structure and not exactly the same as seen in the sample input. It can have any number of s1, s2 tag pairs but each pair will have a unique id.Adding another sample input and output pattern for more information. Input: <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>This is my title</title> </head> <body> <h1 align="center">This <s1 id="1" />is my <s2 id="1" />heading</h1> <p> Sample content <s1 id="2" />Some text here. Some content here. </p> <p> Here you <s2 id="2" />go. </p> </body> </html> Desired output: <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>This is my title</title> </head> <body> <h1 align="center">This <span id="1">is my </span>heading</h1> <p> Sample content <span id="2">Some text here.

  • Form loop db insertion + javascript altering

    - by MrStatic
    I basically need to check if there is an easier way to do this before I rewrite all the code. I have a fairly large form that I have each input named with []'s on the end so I can loop through via php for easy insertion. <input type="hidden" name="currentdate[]" value="<?php echo date('mdY'); ?>"> <td><input style="width: 50px" type="text" name="jackname[]" /></td> <td><input style="width: 20px" type="text" name="jackkey[]" /></td> <td><input style="width: 50px" type="text" name="jackbeg[]" /></td> <td><input style="width: 50px" type="text" name="jackend[]" /></td> <td><input style="width: 50px" type="text" name="jackbegveh" /></td> <td><input style="width: 50px" type="text" name="jackbegmon[]" /></td> <td><input style="width: 50px" type="text" name="jackendveh" /></td> <td><input style="width: 50px" type="text" name="jackendmon[]" /></td> <td><input style="width: 50px" type="text" name="jacktx" disabled /></td> There are quite a few more fields but you get the idea. I then use foreach ($_POST['jackname'] as $row=>$name) { $jackname = $name; $date = $_POST['currentdate'][$row]; $jackkey = $_POST['jackkey'][$row]; $jackbeg = $_POST['jackbeg'][$row]; $jackend = $_POST['jackend'][$row]; $jackbegveh = $_POST['jackbegveh'][$row]; $jackbegmon = $_POST['jackbegmon'][$row]; $jackendveh = $_POST['jackendveh'][$row]; $jackendmon = $_POST['jackendmon'][$row]; $jacktx = $_POST['jacktx'][$row]; if ($jacktx == '') { $jacktx = '0'; } if (empty($jackkey)) { echo 'Skipped empty! <br />'; } else { mysql_query("INSERT INTO `ticket_counts_jackson` VALUES('', '" . $date . "', '" . $jackname . "', '" . $jackkey . "', '" . $jackbeg . "', '" . $jackend . "', '" . $jackbegveh . "', '" . $jackbegmon . "', '" . $jackendveh . "', '" . $jackendmon . "', '" . $jacktx . "')", $mysql_link) or die(mysql_error()); echo 'Added the info the db! <br />'; } } I use the above to loop through the form and add it to the database. Now for my main question. I also want to add in some javascript to do a little math. Basically ($jackendveh - $jackbegveh) - ($jackendmon - $jackbegmon) and have that displayed in jacktx. Currently the only way I know of adding in the math calculations is to rename each input to a unique name and then rewrite my insert from 1 insert to 8 inserts.

  • Where should I create my DbCommand instances?

    - by Domenic
    I seemingly have two choices: Make my class implement IDisposable. Create my DbCommand instances as private readonly fields, and in the constructor, add the parameters that they use. Whenever I want to write to the database, bind to these parameters (reusing the same command instances), set the Connection and Transaction properties, then call ExecuteNonQuery. In the Dispose method, call Dispose on each of these fields. Each time I want to write to the database, write using(var cmd = new DbCommand("...", connection, transaction)) around the usage of the command, and add parameters and bind to them every time as well, before calling ExecuteNonQuery. I assume I don't need a new command for each query, just a new command for each time I open the database (right?). Both of these seem somewhat inelegant and possibly incorrect. For #1, it is annoying for my users that I this class is now IDisposable just because I have used a few DbCommands (which should be an implementation detail that they don't care about). I also am somewhat suspicious that keeping a DbCommand instance around might inadvertently lock the database or something? For #2, it feels like I'm doing a lot of work (in terms of .NET objects) each time I want to write to the database, especially with the parameter-adding. It seems like I create the same object every time, which just feels like bad practice. For reference, here is my current code, using #1: using System; using System.Net; using System.Data.SQLite; public class Class1 : IDisposable { private readonly SQLiteCommand updateCookie = new SQLiteCommand("UPDATE moz_cookies SET value = @value, expiry = @expiry, isSecure = @isSecure, isHttpOnly = @isHttpOnly WHERE name = @name AND host = @host AND path = @path"); public Class1() { this.updateCookie.Parameters.AddRange(new[] { new SQLiteParameter("@name"), new SQLiteParameter("@value"), new SQLiteParameter("@host"), new SQLiteParameter("@path"), new SQLiteParameter("@expiry"), new SQLiteParameter("@isSecure"), new SQLiteParameter("@isHttpOnly") }); } private static void BindDbCommandToMozillaCookie(DbCommand command, Cookie cookie) { long expiresSeconds = (long)cookie.Expires.TotalSeconds; command.Parameters["@name"].Value = cookie.Name; command.Parameters["@value"].Value = cookie.Value; command.Parameters["@host"].Value = cookie.Domain; command.Parameters["@path"].Value = cookie.Path; command.Parameters["@expiry"].Value = expiresSeconds; command.Parameters["@isSecure"].Value = cookie.Secure; command.Parameters["@isHttpOnly"].Value = cookie.HttpOnly; } public void WriteCurrentCookiesToMozillaBasedBrowserSqlite(string databaseFilename) { using (SQLiteConnection connection = new SQLiteConnection("Data Source=" + databaseFilename)) { connection.Open(); using (SQLiteTransaction transaction = connection.BeginTransaction()) { this.updateCookie.Connection = connection; this.updateCookie.Transaction = transaction; foreach (Cookie cookie in SomeOtherClass.GetCookieArray()) { Class1.BindDbCommandToMozillaCookie(this.updateCookie, cookie); this.updateCookie.ExecuteNonQuery(); } transaction.Commit(); } } } #region IDisposable implementation protected virtual void Dispose(bool disposing) { if (!this.disposed && disposing) { this.updateCookie.Dispose(); } this.disposed = true; } public void Dispose() { this.Dispose(true); GC.SuppressFinalize(this); } ~Class1() { this.Dispose(false); } private bool disposed; #endregion }

  • How to scale rotated objects properly in Actionscript 3?

    - by Tom
    This is unfortunately a quite complex issue to explain, so please don't get discouraged by the wall of text - it's there for a reason. ;) I'm working on a transformation manager for flash, written with Actionscript 3. Users can place objects on the screen, for example a rectangle. This rectangle can then be selected and transformed: move, scale or rotate. Because flash by default rotates around the top left point of the object, and I want it to rotate around the center, I created a wrapper setup for each display object (eg. a rectangle). This is how the wrappers are setup: //the position wrapper makes sure that we do get the top left position when we access x and y var positionWrapper:Sprite = new Sprite(); positionWrapper.x = renderObject.x; positionWrapper.y = renderObject.y; //set the render objects location to center at the rotation wrappers top left renderObject.x = 0 - renderObject.width / 2; renderObject.y = 0 - renderObject.height / 2; //now create a rotation wrapper, at the center of the display object var rotationWrapper:Sprite = new Sprite(); rotationWrapper.x = renderObject.width / 2; rotationWrapper.y = renderObject.height / 2; //put the rotation wrapper inside the position wrapper and the render object inside the rotation wrapper positionWrapper.addChild(rotationWrapper); rotationWrapper.addChild(renderObject); Now, the x and y of the object can be accessed and set directly: mainWrapper.x or mainWrapper.y. The rotation can be set and accessed from the child of this main wrapper: mainWrapper.getChildAt(0).rotation. Finally, the width and height of the display object can be retreived and set by getting the child of the rotation wrapper and accessing the display object directly. An example on how I access them: //get wrappers and render object var positionWrapper:Sprite = currentSelection["render"]; var rotationWrapper:Sprite = positionWrapper.getChildAt(0) as Sprite; var renderObject:DisplayObject = rotationWrapper.getChildAt(0); This works perfectly for all initial transformations: moving, scaling and rotating. However, the problem arises when you first rotate an object (eg. 45 degrees) and then scale it. The scaled object is getting out of shape and doesn't scale as it should. This for example happens when you scale to the left. Scaling left is basically adding n width to the object and then reduce the x coord of the position wrapper by n too: renderObject.width -= diffX; positionWrapper.x += diffX; This works when the object is not rotated. However, when it is, the position wrapper won't be rotated as it is a parent of the rotation wrapper. This will make the position wrapper move left horizontally while the width of the object is increased diagonally. I hope this makes any sense, if not, please tell me and I'll try to elaborate more. Now, to the question: should I use a different kind of setup, system or structure? Should I maybe use matrixes, if so, how would you keep a static width/height after rotation? Or how do I fix my current wrapper system for scaling after rotation? Any help is appreciated.

  • Flex XMLListCollection sort on nested tags

    - by gauravgr8
    Hi all, I have a requirement of sorting the <ename> in the XML with in the branch. The XML goes like this: <company> <branch> <name>finance</name> <emp> <ename>rahul</ename> <phno>123456</phno> </emp> <emp> <ename>sunil</ename> <phno>123456</phno> </emp> <emp> <ename>akash</ename> <phno>123456</phno> </emp> <emp> <ename>alok</ename> <phno>123456</phno> </emp> </branch> <branch> <name>finance</name> <emp> <ename>sameer</ename> <phno>123456</phno> </emp> <emp> <ename>rahul</ename> <phno>123456</phno> </emp> <emp> <ename>anand</ename> <phno>123456</phno> </emp> <emp> <ename>sandeep</ename> <phno>123456</phno> </emp> </branch> </company> I tried it with taking XML in XMLList: var xl:XMLList = new XMLList(branch.ename) var xlc:XMLListCollection = new XMLListCollection(xl); then applied sort to the <ename>. I am able to get the sorted but XMLListCollection but the problem is I got the <ename> collection sorted but I need the sorted <ename> in the XML. I tried with deleting the the item in Collection then adding the sorted list but in that case the <name> is lost. Please help me out in sorting <ename> or is there any way to specify nested tags in SortField name? Thanks in advance.

  • Text not Being Placed Correctly In the Center

    - by ThatMacLad
    This is another noobish mistake from me but I've placed some text in my page but after adding some padding to my div tag it's impossible for me to place my Text in the vertical center. Here is a preview of my problem: The CSS: body { background-image: url(../images/body-bg.jpg); font-family: arial; } .cms-head { background-image: url(../images/cms-head.png); background-repeat: no-repeat; width: 850px; height: 50px; padding: 5px; margin-bottom: -10px; } .posts-list { background-image: url(../images/new-post-b.png);; width: 840px; height: 500px; padding: 5px; border-bottom: 1px solid #000000; } .content { width: 850px; height: 500px; margin-left: auto; margin-right: auto; } .edit-post-but { background-image: url(../images/new-button.png); background-repeat: no-repeat; width: 60px; height: 40px; } .post-title { width: 834px; height: 40px; background-image: url(../images/post-head.png); background-repeat: no-repeat; -moz-border-radius: 5px; -webkit-border-radius: 5px; margin-left: auto; margin-right: auto; padding: 5px; font-size: 20px; color: #ffffff; } .bottom { width: 850px; height: 50px; background-image: url(../images/cms-bot.png); background-repeat: no-repeat; } a:active, a:link, a:visited{ color: #ffffff; } a:hover{ text-decoration:none; } The HTML/PHP: <html> <head> <title>Blog Name | Edit Post</title> <link rel="stylesheet" href="css/cms.css" type="text/css" /> </head> <body> <div class="content"> <div class="cms-head"> <a href="newpost.php"><img src="images/new-button.png" /></a> <a href="#"><img src="images/rss-button.png" /></a> </div> <div class="posts-list"> <?php mysql_connect ('localhost', 'root', 'root') ; mysql_select_db ('tmlblog'); $result = mysql_query("SELECT timestamp, id, title FROM php_blog ORDER BY id DESC"); while($row = mysql_fetch_array($result)) { $date = date("l F d Y",$row['timestamp']); $id = $row['id']; $title = strip_tags(stripslashes($row['title'])); if (mb_strlen($title) >= 50) { $title = substr($title, 0, 50); $title = $title .

  • Beginner question: ArrayList can't seem to get it right! Pls help

    - by elementz
    I have been staring at this code all day now, but just can't get it right. ATM I am just pushing codeblocks around without being able to concentrate anymore, with the due time being within almost an hour... So you guys are my last resort here. I am supposed to create a few random balls on a canvas, those balls being stored within an ArrayList (I hope an ArrayList is suitable here: the alternative options to choose from were HashSet and HashMap). Now, whatever I do, I get the differently colored balls at the top of my canvas, but they just get stuck there and refuse to move at all. Apart from that I now get a ConcurrentModificationException, when running the code: java.util.ConcurrentModificationException at java.util.AbstractList$Itr.checkForComodification(AbstractList.java:372) at java.util.AbstractList$Itr.next(AbstractList.java:343) at BallDemo.bounce(BallDemo.java:109) Reading up on that exception, I found out that one can make sure ArrayList is accessed in a threadsafe manner by somehow synchronizing access. But since I have remember fellow students doing without synchronizing, my guess is, that it would actually be the wrong path to go. Maybe you guys could help me get this to work, I at least need those stupid balls to move ;-) /** * Simulate random bouncing balls */ public void bounce(int count) { int ground = 400; // position of the ground line System.out.println(count); myCanvas.setVisible(true); // draw the ground myCanvas.drawLine(50, ground, 550, ground); // Create an ArrayList of type BouncingBalls ArrayList<BouncingBall>balls = new ArrayList<BouncingBall>(); for (int i = 0; i < count; i++){ Random numGen = new Random(); // Creating a random color. Color col = new Color(numGen.nextInt(256), numGen.nextInt(256), numGen.nextInt(256)); // creating a random x-coordinate for the balls int ballXpos = numGen.nextInt(550); BouncingBall bBall = new BouncingBall(ballXpos, 80, 20, col, ground, myCanvas); // adding balls to the ArrayList balls.add(bBall); bBall.draw(); boolean finished = false; } for (BouncingBall bBall : balls){ bBall.move(); } } This would be the original unmodified method we got from our teacher, which only creates two balls: /** * Simulate two bouncing balls */ public void bounce() { int ground = 400; // position of the ground line myCanvas.setVisible(true); myCanvas.drawLine(50, ground, 550, ground); // draw the ground // crate and show the balls BouncingBall ball = new BouncingBall(50, 50, 16, Color.blue, ground, myCanvas); ball.draw(); BouncingBall ball2 = new BouncingBall(70, 80, 20, Color.red, ground, myCanvas); ball2.draw(); // make them bounce boolean finished = false; while(!finished) { myCanvas.wait(50); // small delay ball.move(); ball2.move(); // stop once ball has travelled a certain distance on x axis if(ball.getXPosition() >= 550 && ball2.getXPosition() >= 550) { finished = true; } } ball.erase(); ball2.erase(); } }

  • Using AJAX to display error message Ruby on Rails

    - by bgadoci
    I have built a blog using Ruby on Rails. New to both. I am implementing AJAX pretty effectively until I get to the error handling portion. I allow for comments on posts and do this by rendering a comment partial and remote form in the /views/posts/show.html.erb page. Upon successful save of a comment the show page is updated using views/comments/create.js.rjs and displays a flash notice. I am simply trying to flash a notice when it doesn't save. Searched around and worked this a bit on my own. Can't get it to fly. Here is my code: /views/posts/show.html.erb <div id="comments"> <%= render :partial => @post.comments %> <div id="notice"><%= flash[:notice] %></div> </div> <% remote_form_for [@post, Comment.new] do |f| %> <p> <%= f.label :body, "New Comment" %><br/> <%= f.text_area (:body, :class => "textarea") %> </p> <p> <%= f.label :name, "Name" %><br/> <%= f.text_field (:name, :class => "textfield") %> </p> <p> <%= f.label :email, "Email" %><br/> <%= f.text_field (:email, :class => "textfield") %> </p> <p><%= f.submit "Add Comment" %></p> <% end %> /views/comments/_comment.html.erb <% div_for comment do %> <div id="comment-wrapper"> <% if admin? %> <div id="comment-destroy"><%=link_to_remote "X", :url => [@post, comment], :method => :delete %></div> <% end %> <%= h(comment.body) %><br/><br/> <div class="small">Posted <%= time_ago_in_words(comment.created_at) %> ago by <%= h(comment.name) %> <% if admin? %> | <%= h(comment.email) %> <% end %></div> </div> <% end %> /views/comments/create.js.rjs page.insert_html :bottom, :comments, :partial => @comment page[@comment].visual_effect :highlight page[:new_comment].reset page.replace_html :notice, flash[:notice] flash.discard CommentsController#create def create @post = Post.find(params[:post_id]) @comment = @post.comments.create!(params[:comment]) respond_to do |format| if @comment.save flash[:notice] = "Thanks for adding this comment" format.html { redirect_to @post } format.js else flash[:notice] = "Make sure you include your name and a valid email address" format.html { redirect_to @post } format.js end end end

  • Trouble with Code First DatabaseGenerated Composite Primary Key

    - by Nick Fleetwood
    This is a tad complicated, and please, I know all the arguments against natural PK's, so we don't need to have that discussion. using VS2012/MVC4/C#/CodeFirst So, the PK is based on the date and a corresponding digit together. So, a few rows created today would be like this: 20131019 1 20131019 2 And one created tomorrow: 20131020 1 This has to be automatically generated using C# or as a trigger or whatever. The user wouldn't input this. I did come up with a solution, but I'm having problems with it, and I'm a little stuck, hence the question. So, I have a model: public class MainOne { //[Key] //public int ID { get; set; } [Key][Column(Order=1)] [DatabaseGenerated(DatabaseGeneratedOption.None)] public string DocketDate { get; set; } [Key][Column(Order=2)] [DatabaseGenerated(DatabaseGeneratedOption.None)] public string DocketNumber { get; set; } [StringLength(3, ErrorMessage = "Corp Code must be three letters")] public string CorpCode { get; set; } [StringLength(4, ErrorMessage = "Corp Code must be four letters")] public string DocketStatus { get; set; } } After I finish the model, I create a new controller and views using VS2012 scaffolding. Then, what I'm doing is debugging to create the database, then adding the following instead of trigger after Code First creates the DB [I don't know if this is correct procedure]: CREATE TRIGGER AutoIncrement_Trigger ON [dbo].[MainOnes] instead OF INSERT AS BEGIN DECLARE @number INT SELECT @number=COUNT(*) FROM [dbo].[MainOnes] WHERE [DocketDate] = CONVERT(DATE, GETDATE()) INSERT INTO [dbo].[MainOnes] (DocketDate,DocketNumber,CorpCode,DocketStatus) SELECT (CONVERT(DATE, GETDATE ())),(@number+1),inserted.CorpCode,inserted.DocketStatus FROM inserted END And when I try to create a record, this is the error I'm getting: The changes to the database were committed successfully, but an error occurred while updating the object context. The ObjectContext might be in an inconsistent state. Inner exception message: The object state cannot be changed. This exception may result from one or more of the primary key properties being set to null. Non-Added objects cannot have null primary key values. See inner exception for details. Now, what's interesting to me, is that after I stop debugging and I start again, everything is perfect. The trigger fired perfectly, so the composite PK is unique and perfect, and the data in other columns is intact. My guess is that EF is confused by the fact that there is seemingly no value for the PK until AFTER an insert command is given. Also, appearing to back this theory, is that when I try to edit on of the rows, in debug, I get the following error: The number of primary key values passed must match number of primary key values defined on the entity. Same error occurs if I try to pull the 'Details' or 'Delete' function. Any solution or ideas on how to pull this off? I'm pretty open to anything, even creating a hidden int PK. But it would seem redundant. EDIT 21OCT13 [HttpPost] public ActionResult Create(MainOne mainone) { if (ModelState.IsValid) { var countId = db.MainOnes.Count(d => d.DocketDate == mainone.DocketNumber); //assuming that the date field already has a value mainone.DocketNumber = countId + 1; //Cannot implicitly convert type int to string db.MainOnes.Add(mainone); db.SaveChanges(); return RedirectToAction("Index"); } return View(mainone); } EDIT 21OCT2013 FINAL CODE SOLUTION For anyone like me, who is constantly searching for clear and complete solutions. if (ModelState.IsValid) { String udate = DateTime.UtcNow.ToString("yyyy-MM-dd"); mainone.DocketDate = udate; var ddate = db.MainOnes.Count(d => d.DocketDate == mainone.DocketDate); //assuming that the date field already has a value mainone.DocketNumber = ddate + 1; db.MainOnes.Add(mainone); db.SaveChanges(); return RedirectToAction("Index"); }

  • Strange issues with view switcher after object animator animations

    - by Barry Irvine
    I have two LinearLayout views that contain a number of edit texts and checkboxes for entering user information (name, email address etc). When a validation fails on one of these fields a gone textview is displayed showing the validation error. I have enclosed the two layouts within a ViewSwitcher and I animate between the two views using the ObjectAnimator class. (Since the code needs to support older versions of Android I am actually using the nineoldandroids backwards compatibility library for this). The bulk of the work is performed in my switchToChild method. If I flip the views more than twice then I start to run into strange errors. Firstly although the correct child view of the view animator is displayed it seems that the other view has focus and I can click on the views beneath the current one. I resolved this issue by adding a viewSwitcher.bringChildToFront at the end of the first animation. When I do this however and perform a validation on the 2nd view the "gone" view that I have now set to visible is not displayed (as if the linearlayout is never being re-measured). Here is a subset of the XML file: <ScrollView android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_below="@+id/TitleBar" android:scrollbarAlwaysDrawVerticalTrack="true" android:scrollbarStyle="outsideOverlay" android:scrollbars="vertical" > <ViewSwitcher android:id="@+id/switcher" android:layout_width="fill_parent" android:layout_height="wrap_content" > <LinearLayout android:id="@+id/page_1" android:layout_width="fill_parent" android:layout_height="wrap_content" android:orientation="vertical" > <!-- Lots of subviews here --> <LinearLayout android:id="@+id/page_2" android:layout_width="fill_parent" android:layout_height="wrap_content" android:orientation="vertical" > And this is the main method for flipping between the views: private void switchToChild(final int child) { final ViewSwitcher viewSwitcher = (ViewSwitcher) findViewById(R.id.switcher); if (viewSwitcher.getDisplayedChild() != child) { final Interpolator accelerator = new AccelerateInterpolator(); final Interpolator decelerator = new DecelerateInterpolator(); final View visibleView; final View invisibleView; switch (child) { case 0: visibleView = findViewById(R.id.page_2); invisibleView = findViewById(R.id.page_1); findViewById(R.id.next).setVisibility(View.VISIBLE); findViewById(R.id.back).setVisibility(View.GONE); break; case 1: default: visibleView = findViewById(R.id.page_1); invisibleView = findViewById(R.id.page_2); findViewById(R.id.back).setVisibility(View.VISIBLE); findViewById(R.id.next).setVisibility(View.GONE); break; } final ObjectAnimator visToInvis = ObjectAnimator.ofFloat(visibleView, "rotationY", 0f, 90f).setDuration(250); visToInvis.setInterpolator(accelerator); final ObjectAnimator invisToVis = ObjectAnimator.ofFloat(invisibleView, "rotationY", -90f, 0f).setDuration(250); invisToVis.setInterpolator(decelerator); visToInvis.addListener(new AnimatorListenerAdapter() { @Override public void onAnimationEnd(Animator anim) { viewSwitcher.showNext(); invisToVis.start(); viewSwitcher.bringChildToFront(invisibleView); // If I don't do this the old view can have focus } }); visToInvis.start(); } } Does anyone have any ideas? This is really confusing me!
