  • Are there any nasty side affects if i lock the HttpContext.Current.Cache.Insert method

    - by Ekk
    Apart from blocking other threads reading from the cache what other problems should I be thinking about when locking the cache insert method for a public facing website. The actual data retrieval and insert into the cache should take no more than 1 second, which we can live with. More importantly i don't want multiple thread potentially all hitting the Insert method at the same time. The sample code looks something like: public static readonly object _syncRoot = new object(); if (HttpContext.Current.Cache["key"] == null) { lock (_syncRoot) { HttpContext.Current.Cache.Insert("key", "DATA", null, DateTime.Now.AddMinutes(5), Cache.NoSlidingExpiration, CacheItemPriority.Normal, null); } } Response.Write(HttpContext.Current.Cache["key"]);

  • Java's ThreadPoolExecutor equivalent for C#?

    - by chillitom
    Hi Guys, I used to make good use of Java's ThreadPoolExecutor class and have yet to find a good equivalent in C#. I know of ThreadPool.QueueUserWorkItem which is useful in many cases but no good if you want to control the number of threads assigned to a task or have multiple individual queues for different task types. For example I liked to use a ThreadPoolExecutor with a single thread to guarantee sequential execution of asynchronous calls.. Is there an easy way to do this in C#? Is there a non-static thread pool implementation? Thanks, T.

  • Workaround for richfaces combobox hotkey bug

    - by John
    Hi, Does anyone know a workaround for the bug https://jira.jboss.org/jira/browse/RF-8076 ? Just to clarify things, we have a form with multiple inputs, one of them being a combobox with auto complete features. We've setup a hotkey via <rich:hotKey key="return" ... /> It works great everywhere except in the combobox, and I would really like to get it working on the combobox as well. The behaviour I want when the ENTER key is pressed inside the combobox is: If the combobox context was modified by auto complete then do nothing Else action the event on ENTER key pressed We're running on seam/richfaces. I'm open to any workaround, but simplicity is much sought for. Thanks!

  • Restart Delphi Application Programmatically

    - by Smasher
    It should not be possible to run multiple instances of my application. Therefore the project source contains: CreateMutex (nil, False, PChar (ID)); if (GetLastError = ERROR_ALREADY_EXISTS) then Halt; Now I want to restart my application programmatically. The usual way would be: AppName := PChar(Application.ExeName) ; ShellExecute(Handle,'open', AppName, nil, nil, SW_SHOWNORMAL) ; Application.Terminate; But this won't work in my case because of the mutex. Even if I release the mutex before starting the second instace it won't work because shutdown takes some time and two instance cannot run in parallel (because of common resources and other effects). Is there a way to restart an application with such characteristics? (If possible without an additional executable) Thanks in advance.

  • Setting instance names on keyframes quickly in AS3

    - by Boon
    Right now in Flash CS3 and up (using Actionscript 3) if you have the same instance that is used in multiple keyframes in a layer, and you decide to assign or change the instance name later, you would have to go to each keyframe and set the instance name. This is a big nuisance. Is there a quicker or better way to do this? NOTE: In AS2, you can set the name by using name property of the MovieClip in your code in the onLoad handler of the MovieClip class so it's done once and for all. Unfortunately in AS3, you are not allowed to set the name property anymore.

  • Is it valid for Hibernate list() to return duplicates?

    - by skaffman
    Is anyone aware of the validity of Hibernate's Criteria.list() and Query.list() methods returning multiple occurrences of the same entity? Occasionally I find when using the Criteria API, that changing the default fetch strategy in my class mapping definition (from "select" to "join") can sometimes affect how many references to the same entity can appear in the resulting output of list(), and I'm unsure whether to treat this as a bug or not. The javadoc does not define it, it simply says "The list of matched query results." (thanks guys). If this is expected and normal behaviour, then I can de-dup the list myself, that's not a problem, but if it's a bug, then I would prefer to avoid it, rather than de-dup the results and try to ignore it. Anyone got any experience of this?

  • How do you write a consistent UI Automation for MS? MSAA & UI Automation don't seem to overlap.

    - by Greg
    Working on a general Automation tool, considering moving from Win32 Message hooks to .net UI Automation, however the feature set of UI Automation doesn't cover all we have in Win32 and still doesn't seem to support all the GUI on Windows. One such example is Windows Live Messenger. Windows Live messenger 2009 is still using the older DirectUIHwnd to draw the gui. This means that you can't use windows messages to send to the controls, because the controls don't have their own HWND. It also seems to defeat the new .net UI Automation framework though the documentation seems to make out as if it can be joined in the UI Automation and Microsoft Active Accessibility document. Looking at MS Accessibility pointed to Active Accessibility 2.0 SDK Tools which showed that MSAA can interact with the contents. Is there some trick to getting the older MSAA technology that UI Automation seems to be trying to replace to actually work with UI Automation? I'd rather not have multiple solutions trying to automate the same windows for windows unlike Windows Live Messenger where each of these techniques is valid and will work.

  • WPF: Turning off animations, data binding temporarly for invisible objects?;)

    - by TomTom
    I have a window that contains a tab control - basically multiple sheets with visualizations on them. The visualtizations are: possible very resource intensive during rendering relying on constant data updates to update their underlying models Obviously only one sheet can be visible every time ;) Anyone knows of a good way to turn off all visualization, animations, data binding for a control / panel and it's contained controls? If I would find a way to do that, I could simply turn off all the invisible sheets and reactivate them as needed. The models must be kept running - some of the visual stuff is pretty complex and really relies on constant data updates, and recalculating it when someone switches tabs would be too hard.

  • Free (as in beer) Reverse Image Search API/Library/Service

    - by Bauer
    TinEye provides a great way to "reverse" search by image (i.e. upload/transload an image and have multiple possible sources of that image returned as results.) Since screen-scraping is messy and unreliable, I'm looking for a free API/library/web-service that could offer the same (or similar) reverse-image search function. At present, TinEye offers a commercial API, but since I'll only be using the service for small personal projects, it's hard to justify the cost of the service (the lowest being 1,000 searches for $70 USD). Is anyone aware of such a free service? Or is there a simpler way to approach this (programmatic solution; any language)? I understand that this is a tall order, and submitting the question is really only a last resort in the hope that there is some solution. Example image search is 99designs' StackOverflow logo competition entry by wolv

  • How to make g++ search for header files in a specific directory?

    - by Bane
    I have a project that is subdivided into a few directories with code in them. I'd like to to have g++ search for header files in the project's root directory, so I can avoid different include paths for same header files across multiple source files. Mainly, the root/ directory has sub-directories A/, B/ and C/, all of which have .hpp and .cpp files inside. If some source file in A wanted to include file.hpp, which was in B, it would have to do it like this: #include "../B/file.hpp". Same for another source file that was in C. But, if A itself had sub-directories with files that needed file.hpp, then, it would be inconsistent and would cause errors if I decided to move files (because the include path would be "../../B/file.hpp"). Also, this would need to work from other projects as well, which reside outside of root/. I already know that there is an option to manually copy all my header files into a default-search directory, but I'd like to do this the way I described.

  • Trying to understand MVC Models, Advice?

    - by Tyler
    I am writing my own MVC for the purpose of learning it. I have pretty much everything "down-pat" and my main stuff written besides models due to some trouble understanding them and lack of viable examples. Now, I've been told a model should reprecent a single row, someone told me, your model class should on update/insert and delete rows, anything that involves fetching a single or multiple rows - a "finder" class should be used. So... a) what is a finder class, b) how do I implement it in a useage example, c) Is what I've been told about models correct or is there a better way than "finders"? Advice is much appricated :)

  • Maximum Possible File Name Length in Windows Kernel

    - by Lambert
    I was wondering, what is the longest possible name length allowed by the Windows kernel? E.g.: I know the kernel uses UNICODE_STRING structures to hold all object paths, and since the byte length of a wide-character string is stored inside a USHORT, that allows for a maximum path length of 2^15 - 1 characters. Is there a similar, hard restriction on a file name (rather than path)? (I don't care if NTFS or FAT32 imposes a particular restriction; I'm looking for the longest possible theoretically allowed name in the kernel, assuming no additional file system or shell restrictions.) (Edit: For those wondering why this even matters, consider that normally, traversing a directory is achieved by FindFirstFile/FindNextFile calls, one call per file. Given the function named NtQueryDirectoryFile, which is the underlying system call and which returns multiple file names per call, it's actually possible to take advantage of this maximum-length restriction on the path to make an extremely-fast directory traverser that uses solely the stack as a buffer. Now I'm trying to extend that concept, and I need to know the maximum size of a file name.)

  • Linq2Sql Best Practices

    - by this. __curious_geek
    I'm recently migrating to Linq2Sql and all my future projects will be using Linq2Sql. Having said that, I researched a lot on how to properly plug-in Linq2Sql in application design. what to put at what layer ? How do you design your repositories and business layer services ? Should I use DTOs over Linq2Sql entities on interaction layer ? what things should I be careful about ? what problems did you face ? I did not find any rock-solid material that really talked about one single thing and everyone have their own opinions. I'm looking forward to your ideas on how to integrate/use Linq2Sql in projects. My priority is maintenance[it should be maintenable and when multiple people work on same project] and scalabilty [it should have scope of evolution]. Thanks.

  • How often to run getWritableDatabase() and getReadableDatabase()?

    - by jawonlee
    I'm writing a Service, a Content Provider, and one or more apps. The Service writes new data to the Content Provider's SQLite database every 5 minutes or so plus at user input, and is intended to run pretty much forever in the background. The app, when running, will display data pulled from the Content Provider, and will be refreshed whenever the Service puts more data into the Content Provider's database. Given that the Service only inserts into the database once every five minutes, when is the right time to call SQLiteOpenHelper's getWritableDatabase() / getReadableDatabase()? Is it on the onCreate() of the Content Provider, or should I run it every time there is an insert() and close it at the end of insert()? The data being inserted every 5 minutes will contain multiple inserts.

  • Online Image Slideshow Question. File Access Problems.

    - by msandbot
    Hi, I have a flash .swf file that I embed on my webpage. On my server I have the .swf file and multiple image folders. I would like to load every file in one of those folders into the flash slideshow. How should I go about doing this? I tried used Air but it doesn't work on my system as an application so I doubt it will work online. Eventually I plan on making a menu where you can select different folders to display and since they are of different sizes, a foreach loop would be optimal. Keeping a txt file with the number of images is also possible if theres a way to read that in, but I would prefer the more dynamic approach. I am working towards using php for the website if that helps find a solution. Thanks, -Mike Also my slideshow works great online currently but i have to hardcode in the number of files.

  • SVN Authorization

    - by Weslei
    I am trying to setup SVN authorization (authentication works fine already) and my AuthzSVNAccessFile looks like the following: [groups] todos = user1, user2 proj = user1 [/] @todos = r [/myproj] @proj = rw However, I can checkout the content of proj (as user1) but I can't commit to it... If i change the file changing to the following: [groups] todos = user1, user2 proj = user1 [/] @todos = rw [/myproj] @proj = rw I can successful commit... Anyone knows what's wrong with my access file? I am using SVN with SVNParentPath, to point to a folder containing multiple repositories. The errors it gives are: svn: Error: Server sent unexpected return value (403 Forbidden) in response to CHE CKOUT Thanks.

  • Need some clarification with Patterns (DAO x Gateway)

    - by Marcos Placona
    Me and my colleagues got into this discussion early this morning, and our opinions started to clash a bit, so I decided to get some impartial advice here. One of my colleagues reckons that the DAO should return an object (populated bean). I think it's completely fine when you're returning a recordset with only one line, but think it's overkill if you have to return 10 lines, and create 10 separate objects. I on the other see that the difference between DAO and Gateway pattern is that the gateway pattern will allow you to return a recordset to your business class, which will therefore deal with the recordset data and do whatever it needs to do. My questions here are: Which assumptions are correct? What should the return type be for a DAO (i.e. getContact() - for one record) Should getContacts() (for multiple records) even be on the DAO, if so, what's it's returntype? We seem to be having some sort of confusion about DAO and Gateway Patterns. Should they be used together? Thanks in advance

  • Is there a list of language only character regions for UTF-8 somewhere?

    - by Brehtt
    I'm trying to analyze some UTF-8 encoded documents in a way that recognizes different language characters. For my approach to work I need to ignore non-language characters, such as control characters, mathematical symbols etc. Just trying to dissect the basic Latin section of the UTF standard has resulted in multiple regions, with characters like the division symbol being right in the middle of a range of valid Latin characters. Is there a list somewhere that identifies these regions? Or better yet, a Regex that defines the regions or something in C# that can identify the different characters?

  • How do I branch an individual file in SVN?

    - by Michael Carman
    The subversion concept of branching appears to be focused on creating an [un]stable fork of the entire repository on which to do development. Is there a mechanism for creating branches of individual files? For a use case, think of a common header (*.h) file that has multiple platform-specific source (*.c) implementations. This type of branch is a permanent one. All of these branches would see ongoing development with occasional cross-branch merging. This is in sharp contrast to unstable development/stable release branches which generally have a finite lifespan. I do not want to branch the entire repository (cheap or not) as it would create an unreasonable amount of maintenance to continuously merge between the trunk and all the branches. At present I'm using ClearCase, which has a different concept of branching that makes this easy. I've been asked to consider transitioning to SVN but this paradigm difference is important. I'm much more concerned about being able to easily create alternate versions for individual files than about things like cutting a stable release branch.

  • Data bind enum properties to grid and display description

    - by TrueWill
    This is a similar question to How to bind a custom Enum description to a DataGrid, but in my case I have multiple properties. public enum ExpectationResult { [Description("-")] NoExpectation, [Description("Passed")] Pass, [Description("FAILED")] Fail } public class TestResult { public string TestDescription { get; set; } public ExpectationResult RequiredExpectationResult { get; set; } public ExpectationResult NonRequiredExpectationResult { get; set; } } I'm binding a BindingList<TestResult> to a WinForms DataGridView (actually a DevExpress.XtraGrid.GridControl, but a generic solution would be more widely applicable). I want the descriptions to appear rather than the enum names. How can I accomplish this? (There are no constraints on the class/enum/attributes; I can change them at will.)

  • What should be the image resolution for Nexus One or Droid?

    - by sunil
    Hi, As Android supports multiple devices from different manufacturers there are different screen resolutions supported. The table that is available at http://developer.android.com/intl/fr/guide/practices/screens_support.... is not very clear to me. It shows WVGA and FWVGA in MDPI for Large Screens and HDPI for Normal screens. So, if the image is kept in drawable-mdpi and its resolution is 320 * 480 then which image will be taken by Large Screens device of MDPI. Moreover, there are two screen resolutions for HDPI i.e. 480 * 800 and 480 * 854. So, with what screen resolution the image should be built. I want to place the background image which looks distorted in WVGA emulator since its resolution is 320 * 480. I have read about nine patchable images but I think they are better for button images and edittext images so that they can stretch according to the data in it. Can someone please guide me in this? Regards Sunil

  • GUI system architecture?

    - by topright
    I'm designing GUI (graphical user interface) system for a game engine (C++). Idea is to create a heirarchy of GUI controllers like Focusable, Hoverable, Dragable etc. Every GUI component can attach multiple controllers, they modify component's behaviour. I think it gives flexible system and protects from code duplication. Different instances of the same GUI class can have different complex behaviours (may be, even change it dynamically), so this approach looks practical. The other choice is to add focused, hovered, dragged etc. flags in the base GUI component class. It looks like overhead and not that flexible. Another solution is to use Decorator pattern and wrap objects with FocusDecorator, HoverDecorator etc. Maintaining such system looks a bit harder. Question: What are pitfalls in my solution? May be you have seen a better approaches in GUI systems? What are the best ways of implementing such flexible complex system?

  • Html combo box to database record Id

    - by LanguaFlash
    I'm fairly sure there has to be a simple solution to my problem, but I am a new web developer and can't quite figure it out. On my page I have a combo box whose values are filled from my database. When the user submits the form, how to I go about converting those values back to the record numbers in the database? Up to now I have been just doing a sort of reversed lookup in my database to try to get the record's ID. This has quite a few obvious flaws and I am sure that there has to be a better way. I am used to MS Forms combo boxes where the record data and ID are never separated. But in the case of a web form, I have no way to do multiple columns in the combo box like I am used to. Thanks!

  • Need help using ThemeRoller

    - by Music Magi
    Hi - I'm using DataTables to dress up a table I'm using to display XML results based on an XSL transformation. I have everything working from a technical sense (paging, sorting, filtering), but I'm trying to figure out to use a ThemeRoller theme to make it look like they have on their website. So far, I have added the following file to my project with its reference: <link type="text/css" href="css/custom-theme/jquery-ui-1.8.7.custom.css" rel="stylesheet"/> and enabled ThemeRoller themes using the following as per the DataTables website: $(document).ready(function() { $('#mainTable').dataTable( { "bJQueryUI": true, "sPaginationType": "two_button" }); }); The table gets styled, but it doesn't look right with the header rows being too wide and things being on multiple lines that should be on one line. Any indication as to what I'm doing wrong? Thanks very much in advance.
