  • Drupal vs ExpressionEngine for any kind of project from simple commercial site to complex ecommerce

    - by artmania
    Hi friends... So far I've been using custom cms. lately I developed own cms with CodeIgniter, and I'm actually happy. But recently I take more design and front-end development works than deep development projects. I actually also prefer so... I have many things to do with custom cms, also some security issues, etc. I'm kind of tired of doing everyhing custom, also I want to give more time to my family... Recently I'm seriously considering to go for a ready cms, and develop custom plugins when project need sth specific. This cms should be very flexible to implement any layout. also secured (since i had some hack problems with my custom cms!) I googled so much about this. As a result 2 options: Drupal Expression Engine opensource or licensed matter is not an issue for me at all. I just consider to go for a cms that I can use for any kind of project from simple 4-5 pages company sites to complicated projects like hotels directory, ecommerce portals, etc... As I found out; EE is more userfriendly and doesnt hassle about implementing custom layout as much as Drupal does. Also EE use CodeIgniter that I'm familiar. on the other hand I found out that Drupal is 10000% flexible, we can do anything with that (requires good php knowledge), extremely powerful and has many plugins... So I can't decide!! I want to go for a cms that I will use for looooong years from now on with no problems to implement any kind of project. So which one do you recommend? Appreciate your helps! thanks a lot... Edited: http://expressionengine.com/ee2_sneak_preview/#cost this Commercial License $299.95 is for 1 setup? So I need to purchase new licence for each project? Nothing like I pay once, and use the cms for as many project as I want?

  • CKEditor instance already exists

    - by jackboberg
    I am using jquery dialogs to present forms (fetched via AJAX). On some forms I am using a CKEditor for the textareas. The editor displays fine on the first load. When the user cancels the dialog, I am removing the contents so that they are loaded fresh on a later request. The issue is, once the dialog is reloaded, the CKEditor claims the editor already exists. uncaught exception: [CKEDITOR.editor] The instance "textarea_name" already exists. The API includes a method for destroying existing editors, and I have seen people claiming this is a solution: if (CKEDITOR.instances['textarea_name']) { CKEDITOR.instances['textarea_name'].destroy(); } CKEDITOR.replace('textarea_name'); This is not working for me, as I receive a new error instead: TypeError: Result of expression 'i.contentWindow' [null] is not an object. This error seems to occur on the "destroy()" rather than the "replace()". Has anyone experienced this and found a different solution? Is is possible to 're-render' the existing editor, rather than destroying and replacing it? UPDATED Here is another question dealing with the same problem, but he has provided a downloadable test case.

  • Spring 3 DI using generic DAO interface

    - by Peders
    I'm trying to use @Autowired annotation with my generic Dao interface like this: public interface DaoContainer<E extends DomainObject> { public int numberOfItems(); // Other methods omitted for brevity } I use this interface in my Controller in following fashion: @Configurable public class HelloWorld { @Autowired private DaoContainer<Notification> notificationContainer; @Autowired private DaoContainer<User> userContainer; // Implementation omitted for brevity } I've configured my application context with following configuration <context:spring-configured /> <context:component-scan base-package="com.organization.sample"> <context:exclude-filter expression="org.springframework.stereotype.Controller" type="annotation" /> </context:component-scan> <tx:annotation-driven /> This works only partially, since Spring creates and injects only one instance of my DaoContainer, namely DaoContainer. In other words, if I ask userContainer.numberOfItems(); I get the number of notificationContainer.numberOfItems() I've tried to use strongly typed interfaces to mark the correct implementation like this: public interface NotificationContainer extends DaoContainer<Notification> { } public interface UserContainer extends DaoContainer<User> { } And then used these interfaces like this: @Configurable public class HelloWorld { @Autowired private NotificationContainer notificationContainer; @Autowired private UserContainer userContainer; // Implementation omitted... } Sadly this fails to BeanCreationException: org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.organization.sample.dao.NotificationContainer com.organization.sample.HelloWorld.notificationContainer; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [com.organization.sample.NotificationContainer] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)} Now, I'm a little confused how should I proceed or is using multiple Dao's even possible. Any help would be greatly appreciated :)

  • What do you mean by the expressiveness in a programming language?

    - by prosseek
    I see a lot of the word 'expressiveness' when people want to stress one language is better than the other. But I don't see exactly what they mean by it. Is it the verboseness/succinctness? I mean, if one language can write down something shorter than the other, does that mean expressiveness? Please refer to my other question - http://stackoverflow.com/questions/2411772/article-about-code-density-as-a-measure-of-programming-language-power Is it the power of the language? Paul Graham says that one language is more powerful than the other language in a sense that one language can do that the other language can't do (for example, LISP can do something with macro that the other language can't do). Is it just something that makes life easier? Regular expression can be one of the examples. Is it a different way of solving the same problem: something like SQL to solve the search problem? What do you think about the expressiveness of a programming language? Can you show the expressiveness using some code? What's the relationship with the expressiveness and DSL? Do people come up with DSL to get the expressiveness?

  • Java conditional operator ?: result type

    - by Wangnick
    I'm a bit puzzled about the conditional operator. Consider the following two lines: Float f1 = false? 1.0f: null; Float f2 = false? 1.0f: false? 1.0f: null; Why does f1 become null and the second statement throws a NullPointerException? Langspec-3.0 para 15.25 sais: Otherwise, the second and third operands are of types S1 and S2 respectively. Let T1 be the type that results from applying boxing conversion to S1, and let T2 be the type that results from applying boxing conversion to S2. The type of the conditional expression is the result of applying capture conversion (§5.1.10) to lub(T1, T2) (§15.12.2.7). So for false?1.0f:null T1 is Float and T2 is the null type. But what is the result of lub(T1,T2)? This para 15.12.2.7 is just a bit too much ... BTW, I'm using 1.6.0_18 on Windows. PS: I know that Float f2 = false? (Float) 1.0f: false? (Float) 1.0f: null; doesn't throw NPE.

  • Need help regarding one LALR(1) parsing.

    - by AppleGrew
    I am trying to parse a context-free language, called Context Free Art. I have created its parser in Javascript using a YACC-like JS LALR(1) parser generator JSCC. Take the example of following CFA (Context Free Art) code. This code is a valid CFA. startshape A rule A { CIRCLE { s 1} } Notice the A and s in above. s is a command to scale the CIRCLE, but A is just a name of this rule. In the language's grammar I have set s as token SCALE and A comes under token STRING (I have a regular expression to match string and it is at the bottom of of all tokens). This works fine, but in the below case it breaks. startshape s rule s { CIRCLE { s 1} } This too is a perfectly valid code, but since my parser marks s after rule as SCALE token so it errors out saying that it was expecting STRING. Now my question is, if there is any way to re-write the production rules of the parser to account for this? The related production rule is:- rule: RULE STRING '{' buncha_replacements '}' [* rule(%2, 1) *] | RULE STRING RATIONAL '{' buncha_replacements '}' [* rule(%2, 1*%3) *] ; One simple solution I can think of is create a copy of above rule with STRING replaced by SCALE, but this is just one of the many similar rules which would need such fixing. Furthermore there are many other terminals which can get matched to STRING. So that means way too many rules!

  • Async.Parallel or Array.Parallel.Map ?

    - by gurteen2
    Hello- I'm trying to implement a pattern I read from Don Syme's blog (http://blogs.msdn.com/dsyme/archive/2010/01/09/async-and-parallel-design-patterns-in-f-parallelizing-cpu-and-i-o-computations.aspx) which suggests that there are opportunities for massive performance improvements from leveraging asynchronous I/O. I am currently trying to take a piece of code that "works" one way, using Array.Parallel.Map, and see if I can somehow achieve the same result using Async.Parallel, but I really don't understand Async.Parallel, and cannot get anything to work. I have a piece of code (simplified below to illustrate the point) that successfully retrieves an array of data for one cusip. (A price series, for example) let getStockData cusip = let D = DataProvider() let arr = D.GetPriceSeries(cusip) return arr let data = Array.Parallel.map (fun x -> getStockData x) stockCusips So this approach contructs an array of arrays, by making a connection over the internet to my data vendor for each stock (which could be as many as 3000) and returns me an array of arrays (1 per stock, with a price series for each one). I admittedly don't understand what goes on underneath Array.Parallel.map, but am wondering if this is a scenario where there are resources wasted under the hood, and it actually could be faster using asynchronous I/O? So to test this out, I have attempted to make this function using asyncs, and I think that the function below follows the pattern in Don Syme's article using the URLs, but it won't compile with "let!". let getStockDataAsync cusip = async { let D = DataProvider() let! arr = D.GetData(cusip) return arr } The error I get is: This expression was expected to have type Async<'a but here has type obj It compiles fine with "let" instead of "let!", but I had thought the whole point was that you need the exclamation point in order for the command to run without blocking a thread. So the first question really is, what's wrong with my syntax above, in getStockDataAsync, and then at a higher level, can anyone offer some additional insight about asychronous I/O and whether the scenario I have presented would benefit from it, making it potentially much, much faster than Array.Parallel.map? Thanks so much.

  • Explicit Type Conversion and Multiple Simple Type Specifiers

    - by James McNellis
    To value initialize an object of type T, one would do something along the lines of one of the following: T x = T(); T x((T())); My question concerns types specified by a combination of simple type specifiers, e.g., unsigned int: unsigned int x = unsigned int(); unsigned int x((unsigned int())); Visual C++ 2008 and Intel C++ Compiler 11.1 accept both of these without warnings; Comeau 4.3.10.1b2 and g++ 3.4.5 (which is, admittedly, not particularly recent) do not. According to the C++ standard (C++03 5.2.3/2, expr.type.conv): The expression T(), where T is a simple-type-specifier (7.1.5.2) for a non-array complete object type or the (possibly cv-qualified) void type, creates an rvalue of the specified type, which is value-initialized 7.1.5.2 says, "the simple type specifiers are," and follows with a list that includes unsigned and int. Therefore, given that in 5.2.3/2, "simple-type-specifier" is singular, and unsigned and int are two type specifiers, are the examples above that use unsigned int invalid? (and, if so, the followup is, is it incorrect for Microsoft and Intel to support said expressions?) This question is more out of curiosity than anything else; for all of the types specified by a combination of multiple simple type specifiers, value initialization is equivalent to zero initialization. (This question was prompted by comments in response to this answer to a question about initialization).

  • How do I get Visual Studio build process to pass condition to library(external) project

    - by Billy Talented
    I have tried several solutions for this problem. Enough to know I do not know enough about MSBuild to do this elegantly but I feel like there should be a method. I have a set of libraries for working with .net projects. A few of the projects utilize System.Web.Mvc - which recently released Version 2 - and we are looking forward to the upgrade. Currently sites which reference this library reference it directly by the project(csproj) on the developer's computer - not a built version of the library so that changes and source code case easily be viewed when dealing code from this library. This works quite well and would prefer to not have to switch to binary references (but will if this is the only solution). The problem I have is that because of some of the functionality that was added onto the MVC1 based library (view engines, model binders etc) several of the sites reliant on these libraries need to stay on MVC1 until we have full evaluated and tested them on MVC2. I would prefer to not have to fork or have two copies on each dev machine. So what I would like to be able to do is set a property group value in the referencing web application and have this read by the above mentions library with the caviat that when working directly on the library via its containing solution I would like to be able to control this via Configuration Manager by selecting a build type and that property overriding the build behavior of the solution (i.e. 'Debug - MVC1' vs 'Debug -MVC2') - I have this working via: <Choose> <When Condition=" '$(Configuration)|$(Platform)' == 'Release - MVC2|AnyCPU' Or '$(Configuration)|$(Platform)' == 'Debug - MVC2|AnyCPU'"> <ItemGroup> <Reference Include="System.Web.Mvc, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL"> </Reference> <Reference Include="Microsoft.Web.Mvc, Version=1.0.0.0, Culture=neutral, processorArchitecture=MSIL"> <SpecificVersion>False</SpecificVersion> <HintPath>..\Dependancies\Web\MVC2\Microsoft.Web.Mvc.dll</HintPath> </Reference> </ItemGroup> </When> <Otherwise> <ItemGroup> <Reference Include="System.Web.Mvc, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL"> <SpecificVersion>False</SpecificVersion> <HintPath>..\Dependancies\Web\MVC\System.Web.Mvc.dll</HintPath> </Reference> </ItemGroup> </Otherwise> The item that I am struggling with is the cross solution issue(solution TheWebsite references this project and needs to control which build property to use) that I have not found a way to work with that I think is a solid solution that enabled the build within visual studio to work as it has to date. Other bits: we are using VS2008, Resharper, TeamCity for CI, SVN for source control.

  • Regex query: how can I search PDFs for a phrase where words in that phrase appear on more than one l

    - by Alison
    I am trying to set up an index page for the weekly magazine I work on. It is to show readers the names of companies mentioned in that weeks' issue, plus the page numbers they are appear on. I want to search all the PDF files for the week, where one PDF = one magazine page (originally made in Adobe InDesign CS3 and Adobe InCopy CS3). I have set up a list of companies I want to search for and, using PowerGREP and using delimited regular expressions, I am able to find most page numbers where a company is mentioned. However, where a company name contains two or more words, the search I am running will not pick up instances where the name appears over more than one line. For example, when looking for "CB Richard Ellis" and "Cushman & Wakefield", I got no result when the text appeared like this: DTZ beat BNP PRE, CB [line break here] Richard Ellis and Cushman & [line break here] Wakefield to secure the contract. [line end here] Could someone advise me on how to write a regular expression that will ignore white space between words and ignore line endings OR one that will look for the words including all types of white space (ie uneven spaces between words; spaces at the end of lines or line endings; and tabs (I am guessing that this info is imbedded somehow in PDF files). Here is a sample of the set of terms I have asked PowerGREP to search for: \bCB Richard Ellis\b \bCB Richard Ellis Hotels\b \bCentaur Services\b \bChapman Herbert\b \bCharities Property Fund\b \bChetwoods Architects\b \bChurch Commissioners\b \bClive Emson\b \bClothworkers’ Company\b \bColliers CRE\b \bCombined English Stores Group\b \bCommercial Estates Group\b \bConnells\b \bCooke & Powell\b \bCordea Savills\b \bCrown Estate\b \bCushman & Wakefield\b \bCWM Retail Property Advisors\b [Note that there is a delimited hard return between each \b at the end of each phrase and beginnong of the next phrase.] By the way, I am a production journalist and not usually involved in finding IT-type solutions and am finding it difficult to get to grips with the technical language on the PowerGREP site.

  • jQuery document.ready + Asp.Net ContentPlaceholder cause Visual Studio intellisence problems

    - by Konstantin
    Hi! I want to execute JavaScript when document is ready without much syntax overhead. The idea is to use Site.Master and ContentPlaceholder: <script type="text/javascript"> $(document).ready(function () { <asp:ContentPlaceHolder ID="OnReadyScript" runat="server" /> }); </script> and in inherited pages just write plain code: <asp:Content ID="Content3" ContentPlaceHolderID="OnReadyScript" runat="server"> $("#Login").focus(); </asp:Content> It works fine but Visual Studio complains and gives warnings. Warning in master page is Expected expression at the line <asp:ContentPlaceHolder. In inherited pages warning is Could not find 'OnReadyScript' in the current master page or pages. I tried using Writer.Write in master page to render script tag and wrapping code: <% Writer.Write(@"<script type=""text/javascript"">$(document).ready(function () {"); %> <asp:ContentPlaceHolder ID="OnReadyScrit" runat="server" /> <% Writer.Write(@"});"); %> but page rendering terminates after opening script tag is rendered. Html basically ends with <script type="text/javascript"> How can I make it work?

  • CSS div/overflow Question: Why does the first HTML file work but not the second?

    - by kidvid
    Notice how the first HTML/CSS works when you re-size the browser horizontally. It will shrink no further than around 800 pixels, but it will expand as far as you drag the right edge of the browser. It will also correctly overflow the table at the top and scroll it horizontally. The thing I don't like about the first code snippet is where the scrollbar is. I want it to show up within the borders of the fieldset, so even if I narrow the browser down to 800 pixels wide, I can see both the left and right sides of the fieldset's border. The second code snippet is exactly the same as the first except I add another div tag to the mix, inside of the field set and around the grid. Notice how the top fieldset's width won't correctly shrink when you make the viewport of your browser narrower. Any ideas on why it doesn't work, what I can do to get it to work like the first code snippet? I don't think I'm describing this clearly, but if you run the two side by side, and expand and contract the horizontal edge of your browser windows, you'll see the differences between the two. I'm pretty new to CSS and HTML layout, so my understanding of why CSS handles sizing the way it does in some situations is still really confusing to me.

  • Can someone please explain this lazy evaluation code?

    - by Tejs
    So, this question was just asked on SO: http://stackoverflow.com/questions/2740001/how-to-handle-an-infinite-ienumerable My sample code: public static void Main(string[] args) { foreach (var item in Numbers().Take(10)) Console.WriteLine(item); Console.ReadKey(); } public static IEnumerable<int> Numbers() { int x = 0; while (true) yield return x++; } Can someone please explain why this is lazy evaluated? I've looked up this code in Reflector, and I'm more confused than when I began. Reflector outputs: public static IEnumerable<int> Numbers() { return new <Numbers>d__0(-2); } For the numbers method, and looks to have generated a new type for that expression: [DebuggerHidden] public <Numbers>d__0(int <>1__state) { this.<>1__state = <>1__state; this.<>l__initialThreadId = Thread.CurrentThread.ManagedThreadId; } This makes no sense to me. I would have assumed it was an infinite loop until I put that code together and executed it myself.

  • Sorting Anonymous Types

    - by strobaek
    I have a question of how to sort an anonymous type. Using Linq2SQL I have the following query, which returns a list of submissions: var submissions = EventSubmissions .Where(s => s.EventId.Equals(eventId)); Consider the following interface (somewhat simplyfied): public interface IQuerySorter { IOrderedQueryable Sort(IQueryable query); IOrderedQueryable<T> Sort<T, U>(IQueryable<T> query, Expression<Func<T,U>> selector); ... } Using this interface allows me to implement a number of 'sorters', e.g. on Date, Rating or whether or not a submission has been nominated (for voting). sortedQuery = sorter.Sort(submissions) So far so good. A submission can be made "votable". I get the number of votes a nominated submission may have using the following query: var withVoteCount = submissions .Select(s => new {NumberOfVotes = s.Votes.Count(), Submission = s}); I would like to sort this new query by NumberOfVotes using my "general" sorter class, but run into the problem that the anonymous type/member does not seem to live outside the repository-method, hence I am unable to sort on it. Any input would be greatly appreciated.

  • Results Delphi users who wish to use HID USB in windows

    - by Lex Dean
    Results Delphi users who wish to use HID USB in windows HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB Contain a list if keys containing vender ID and Producer ID numbers that co inside with the USB web sites data base. These numbers and the GUID held within the key gives important information to execute the HID.dll that is otherwise imposable to execute. The Control Panel/System/Hardware/Device manager/USB Serial Bus Controllers/Mass Storage Devices/details simply lists the registry data. The access to the programmer has been documented through the API32.dll with a number of procedures that accesses the registry. But that is not the problem yet it looks like the problem!!!!!!!!! The key is info about the registry and how to use it. These keys are viewed in RegEdit.exe it’s self. Some parts of the registry like the USB have been given a windows security system type of protection with a Aurthz.dll to give the USB read and right protection. Even the api32.dll. Now only Microsoft give out these details and we all know Microsoft hate Delphi. Now C users have enjoyed this access for over 10 years now. Now some will make out that you should never give out such information because some idiot may make a stupid virus (true), but the argument is also do Delphi users need to be denied USB access for another ten years!!!!!!!!!!!!. What I do not have is the skill in is assembly code. I’m seeking for some one that can trace how regedit.exe gets its access through Aurthz.dll to access the USB data. So I’m asking all who reads this:- to partition any friend they have that has this skill to get the Aurthz.dll info needed. I find communicating with USB.org they reply when they have a positive email reply but do not bother should their email be a slightly negative policy. For all simple reasoning, all that USB had to do was to have a secure key as they have done, and to update the same data into a unsecured key every time the data is changed for USB developer to access. And not bother developers access to Aurthz.dll. Authz.dll with these functions for USB:- AuthzFreeResourceManager AuthzFreeContext AuthzAccessCheck(Flags: DWORD; AuthzClientContext: AUTHZ_CLIENT_CONTEXT_HANDLE; pRequest: PAUTHZ_ACCESS_REQUEST; AuditInfo: AUTHZ_AUDIT_INFO_HANDLE; pSecurityDescriptor: PSECURITY_DESCRIPTOR; OptionalSecurityDescriptorArray: PSECURITY_DESCRIPTOR; OptionalSecurityDescriptorCount: DWORD; //OPTIONAL, Var pReply: AUTHZ_ACCESS_REPLY; pAuthzHandle: PAUTHZ_ACCESS_CHECK_RESULTS_HANDLE): BOOl; AuthzInitializeContextFromSid(Flags: DWORD; UserSid: PSID; AuthzResourceManager: AUTHZ_RESOURCE_MANAGER_HANDLE; pExpirationTime: int64; Identifier: LUID; DynamicGroupArgs: PVOID; pAuthzClientContext: PAUTHZ_CLIENT_CONTEXT_HANDLE): BOOL; AuthzInitializeResourceManager(flags: DWORD; pfnAccessCheck: PFN_AUTHZ_DYNAMIC_ACCESS_CHECK; pfnComputeDynamicGroups: PFN_AUTHZ_COMPUTE_DYNAMIC_GROUPS; pfnFreeDynamicGroups: PFN_AUTHZ_FREE_DYNAMIC_GROUPS; ResourceManagerName: PWideChar; pAuthzResourceManager: PAUTHZ_RESOURCE_MANAGER_HANDLE): BOOL; further in Authz.h on kolers.com J Lex Dean.

  • Starter question of declarative style SQLAlchemy relation()

    - by jfding
    I am quite new to SQLAlchemy, or even database programming, maybe my question is too simple. Now I have two class/table: class User(Base): __tablename__ = 'users' id = Column(Integer, primary_key=True) name = Column(String(40)) ... class Computer(Base): __tablename__ = 'comps' id = Column(Integer, primary_key=True) buyer_id = Column(None, ForeignKey('users.id')) user_id = Column(None, ForeignKey('users.id')) buyer = relation(User, backref=backref('buys', order_by=id)) user = relation(User, backref=backref('usings', order_by=id)) Of course, it cannot run.

  • jQuery DatePicker - 'fake' click on page load

    - by Danny
    Hey! I've got a quick question about the jQuery UI DatePicker. When I load the page, defaultDate: 0 will work fine with selecting the current day's date. I would like to create a 'fake' click on the date so it will execute my JavaScript function and retrieve information from the database. I tried calling the function when the page loads but that doesn't work. $(document).ready(function(){ $("#datepicker").datepicker({ gotoCurrent: false, onSelect: function(date, inst) { ajaxFunction(date); }, dateFormat: 'dd-mm-yy', defaultDate: 0, changeMonth: true, changeYear: true }); }); //Browser Support Code function ajaxFunction(date){ var ajaxRequest; // The variable that makes Ajax possible! try{ // Opera 8.0+, Firefox, Safari ajaxRequest = new XMLHttpRequest(); } catch (e){ // Internet Explorer Browsers try{ ajaxRequest = new ActiveXObject("Msxml2.XMLHTTP"); } catch (e) { try{ ajaxRequest = new ActiveXObject("Microsoft.XMLHTTP"); } catch (e){ // Something went wrong alert("Your browser broke!"); return false; } } } // Create a function that will receive data sent from the server ajaxRequest.onreadystatechange = function(){ if(ajaxRequest.readyState == 4){ var ajaxDisplay = document.getElementById('ajaxDiv'); ajaxDisplay.innerHTML = ajaxRequest.responseText; } } var queryString = "?date=" + date; ajaxRequest.open("GET", "getDiary.php" + queryString, true); ajaxRequest.send(null); } function ajaxAdd(){ var ajaxRequest; // The variable that makes Ajax possible! try{ // Opera 8.0+, Firefox, Safari ajaxRequest = new XMLHttpRequest(); } catch (e){ // Internet Explorer Browsers try{ ajaxRequest = new ActiveXObject("Msxml2.XMLHTTP"); } catch (e) { try{ ajaxRequest = new ActiveXObject("Microsoft.XMLHTTP"); } catch (e){ // Something went wrong alert("Your browser broke!"); return false; } } } var day1 = $("#datepicker").datepicker('getDate').getDate(); var day2 = (day1 < 10) ? '0' + day1 : day1; var month1 = $("#datepicker").datepicker('getDate').getMonth() + 1; var month2 = (month1 < 10) ? '0' + month1 : month1; var year1 = $("#datepicker").datepicker('getDate').getFullYear(); var year2 = (year1 < 1000) ? year1 + 1900 : year1; var fullDate = day2 + "-" + month2 + "-" + year2; var queryString = "?breakfast=" + diary1.breakfast.value; queryString = queryString + "&lunch=" + diary1.lunch.value; queryString = queryString + "&dinner=" + diary1.dinner.value; queryString = queryString + "&date=" + fullDate; ajaxRequest.open("GET", "addDiary.php" + queryString, true); ajaxRequest.send(null); alert("Added value to database!"); diary1.breakfast.value = ""; diary1.lunch.value = ""; diary1.dinner.value = ""; ajaxFunction(fullDate); } I have pasted my DatePicker class, and the two functions that are used (one to retrieve information from the database, and one to store). Basically I want to mirror the onSelect: function on the DatePicker, but when the page first loads. Thanks!

  • wpf window refresh works at first, then stops

    - by mcl
    I've got a routine that grabs a list of all images in a directory, then runs an MD5 digest on all of them. Since this takes a while to do, I pop up a window with a progress bar. The progress bar is updated by a lambda that I pass in to the long-running routine. The first problem was that the progress window was never updated (which is normal in WPF I guess). Since WPF lacks a Refresh() command I fixed this with a call to Dispatcher.Invoke(). Now the progress bar is updated for a while, then the window stops being updated. The long-running work does eventually finish and the windows go back to normal. I have already tried a BackgroundWorker and quickly became frustrated by a threading issue related to an event triggered by the long-running process. So if that's really the best solution and I just need to learn the paradigm better, please say so. But I'd be really much happier with the approach I've got here, except that it stops updating after a bit (for example, in a folder with 1000 files, it might update for 50-100 files, then "hang"). The UI does not need to be responsive during this activity, except to report on progress. Anyway, here's the code. First the progress window itself: public partial class ProgressWindow : Window { public ProgressWindow(string title, string supertext, string subtext) { InitializeComponent(); this.Title = title; this.SuperText.Text = supertext; this.SubText.Text = subtext; } internal void UpdateProgress(int count, int total) { this.ProgressBar.Maximum = Convert.ToDouble(total); this.ProgressBar.Value = Convert.ToDouble(count); this.SubText.Text = String.Format("{0} of {1} finished", count, total); this.Dispatcher.Invoke(DispatcherPriority.Render, EmptyDelegate); } private static Action EmptyDelegate = delegate() { }; } <Window x:Class="Pixort.ProgressWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Pixort Progress" Height="128" Width="256" WindowStartupLocation="CenterOwner" WindowStyle="SingleBorderWindow" ResizeMode="NoResize"> <DockPanel> <TextBlock DockPanel.Dock="Top" x:Name="SuperText" TextAlignment="Left" Padding="6"></TextBlock> <TextBlock DockPanel.Dock="Bottom" x:Name="SubText" TextAlignment="Right" Padding="6"></TextBlock> <ProgressBar x:Name="ProgressBar" Height="24" Margin="6"/> </DockPanel> </Window> The long running method (in Gallery.cs): public void ImportFolder(string folderPath, Action<int, int> progressUpdate) { string[] files = this.FileIO.GetFiles(folderPath); for (int i = 0; i < files.Length; i++) { // do stuff with the file if (null != progressUpdate) { progressUpdate.Invoke(i + 1, files.Length); } } } Which is called thusly: ProgressWindow progress = new ProgressWindow("Import Folder Progress", String.Format("Importing {0}", folder), String.Empty); progress.Show(); this.Gallery.ImportFolder(folder, ((c, t) => progress.UpdateProgress(c, t))); progress.Close();

  • Help with JPQL query

    - by Robert
    I have to query a Message that is in a provided list of Groups and has not been Deactivated by the current user. Here is some pseudo code to illustrate the properties and entities: class Message { private int messageId; private String messageText; } class Group { private String groupId; private int messageId; } class Deactivated { private String userId; private int messageId; } Here is an idea of what I need to query for, it's the last AND clause that I don't know how to do (I made up the compound NOT IN expression). Filtering the deactivated messages by userId can result in multiple messageIds, how can I check if that subset of rows does not contain the messageId? SELECT msg FROM Message msg, Group group, Deactivated unactive WHERE group.messageId = msg.messageId AND (group.groupId = 'groupA' OR group.groupId = 'groupB' OR ...) AND ('someUserId', msg.messageId) NOT IN (unactive.userId, unactive.messageId) I don't know the number of groupIds ahead of time -- I receive them as a Collection<String> so I'll need to traverse them and add them to the JPQL dynamically.

  • Constant Memory Leak in SpeechSynthesizer

    - by DudeFX
    I have developed a project which I would like to release which uses c#, WPF and the System.Speech.Synthesizer object. The issue preventing the release of this project is that whenever SpeakAsync is called it leaves a memory leak that grows to the point of eventual failure. I believe I have cleaned up properly after using this object, but cannot find a cure. I have run the program through Ants Memory Profiler and it reports that WAVEHDR and WaveHeader is growing with each call. I have created a sample project to try to pinpoint the cause, but am still at a loss. Any help would be appreciated. The project uses VS2008 and is a c# WPF project that targets .NET 3.5 and Any CPU. You need to manually add a reference to System.Speech. Here is the Code: <Window x:Class="SpeechTest.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" Height="300" Width="300"> <Grid> <StackPanel Orientation="Vertical"> <Button Content="Start Speaking" Click="Start_Click" Margin="10" /> <Button Content="Stop Speaking" Click="Stop_Click" Margin="10" /> <Button Content="Exit" Click="Exit_Click" Margin="10"/> </StackPanel> </Grid> // Start of code behind using System; using System.Windows; using System.Speech.Synthesis; namespace SpeechTest { public partial class Window1 : Window { // speak setting private bool speakingOn = false; private int curLine = 0; private string [] speakLines = { "I am wondering", "Why whenever Speech is called", "A memory leak occurs", "If you run this long enough", "It will eventually crash", "Any help would be appreciated" }; public Window1() { InitializeComponent(); } private void Start_Click(object sender, RoutedEventArgs e) { speakingOn = true; SpeakLine(); } private void Stop_Click(object sender, RoutedEventArgs e) { speakingOn = false; } private void Exit_Click(object sender, RoutedEventArgs e) { App.Current.Shutdown(); } private void SpeakLine() { if (speakingOn) { // Create our speak object SpeechSynthesizer spk = new SpeechSynthesizer(); spk.SpeakCompleted += new EventHandler(spk_Completed); // Speak the line spk.SpeakAsync(speakLines[curLine]); } } public void spk_Completed(object sender, SpeakCompletedEventArgs e) { if (sender is SpeechSynthesizer) { // get access to our Speech object SpeechSynthesizer spk = (SpeechSynthesizer)sender; // Clean up after speaking (thinking the event handler is causing the memory leak) spk.SpeakCompleted -= new EventHandler(spk_Completed); // Dispose the speech object spk.Dispose(); // bump it curLine++; // check validity if (curLine = speakLines.Length) { // back to the beginning curLine = 0; } // Speak line SpeakLine(); } } } } I run this program on Windows 7 64 bit and it will run and eventually halt when attempting to create a new SpeechSynthesizer object. When run on Windows Vista 64 bit the memory will grow from a starting point of 34k to so far about 400k and growing. Can anyone see anything in the code that might be causing this, or is this an issue with the Speech object itself. Any help would be appreciated.

  • How do I escape a LIKE clause using NHibernate Criteria?

    - by Jon Seigel
    The code we're using is straight-forward in this part of the search query: myCriteria.Add( Expression.InsensitiveLike("Code", itemCode, MatchMode.Anywhere)); and this works fine in a production environment. The issue is that one of our clients has item codes that contain % symbols which this query needs to match. The resulting SQL output from this code is similar to: SELECT ... FROM ItemCodes WHERE ... AND Code LIKE '%ItemWith%Symbol%' which clearly explains why they're getting some odd results in item searches. Is there a way to enable escaping using the programmatic Criteria methods? Addendum: We're using a slightly old version of NHibernate, 2.1.0.4000 (current as of writing is 2.1.2.4853), but I checked the release notes, and there was no mention of a fix for this. I didn't find any open issue in their bugtracker either. We're using SQL Server, so I can escape the special characters (%, _, [, and ^) in code really easily, but the point of us using NHibernate was to make our application database-engine-independent as much as possible. Neither Restrictions.InsensitiveLike() nor HqlQueryUtil.GetLikeExpr() escape their inputs, and removing the MatchMode parameter makes no difference as far as escaping goes.

  • Shift-reduce: when to stop reducing?

    - by Joey Adams
    I'm trying to learn about shift-reduce parsing. Suppose we have the following grammar, using recursive rules that enforce order of operations, inspired by the ANSI C Yacc grammar: S: A; P : NUMBER | '(' S ')' ; M : P | M '*' P | M '/' P ; A : M | A '+' M | A '-' M ; And we want to parse 1+2 using shift-reduce parsing. First, the 1 is shifted as a NUMBER. My question is, is it then reduced to P, then M, then A, then finally S? How does it know where to stop? Suppose it does reduce all the way to S, then shifts '+'. We'd now have a stack containing: S '+' If we shift '2', the reductions might be: S '+' NUMBER S '+' P S '+' M S '+' A S '+' S Now, on either side of the last line, S could be P, M, A, or NUMBER, and it would still be valid in the sense that any combination would be a correct representation of the text. How does the parser "know" to make it A '+' M So that it can reduce the whole expression to A, then S? In other words, how does it know to stop reducing before shifting the next token? Is this a key difficulty in LR parser generation?
