  • Rails HTML editor to create forms

    - by Ignace
    Hey all, I'm looking for a HTML editor which can be (easiliy) integrated in a RoR app that has the possibility to create forms. Not forms per se, but I need the possibility to add radiobuttons, input fields, checkboxes and so on. I loved the smoothness of TinyMCE, but apparently this doesn't take me far enough. Does there exists such a gem/plugin? Thanks!

  • Performance - FunctionCall vs Event vs Action vs Delegate

    - by hwcverwe
    Currently I am using Microsoft Sync Framework to synchronize databases. I need to gather information per record which is inserted/updated/deleted by Microsoft Sync Framework and do something with this information. The sync speed can go over 50.000 records per minute. So that means my additional code need to be very lightweight otherwise it will be a huge performance penalty. Microsoft Sync Framework raises an SyncProgress event for each record. I am subscribed to that code like this: // Assembly1 SyncProvider.SyncProgress += OnSyncProgress; // .... private void OnSyncProgress(object sender, DbSyncProgressEventArgs e) { switch (args.Stage) { case DbSyncStage.ApplyingInserts: // MethodCall/Delegate/Action<>/EventHandler<> => HandleInsertedRecordInformation // Do something with inserted record info break; case DbSyncStage.ApplyingUpdates: // MethodCall/Delegate/Action<>/EventHandler<> => HandleUpdatedRecordInformation // Do something with updated record info break; case DbSyncStage.ApplyingDeletes: // MethodCall/Delegate/Action<>/EventHandler<> => HandleDeletedRecordInformation // Do something with deleted record info break; } } Somewhere else in another assembly I have three methods: // Assembly2 public class SyncInformation { public void HandleInsertedRecordInformation(...) {...} public void HandleUpdatedRecordInformation(...) {...} public void HandleInsertedRecordInformation(...) {...} } Assembly2 has a reference to Assembly1. So Assembly1 does not know anything about the existence of the SyncInformation class which need to handle the gathered information. So I have the following options to trigger this code: use events and subscribe on it in Assembly2 1.1. EventHandler< 1.2. Action< 1.3. Delegates using dependency injection: public class Assembly2.SyncInformation : Assembly1.ISyncInformation Other? I know the performance depends on: OnSyncProgress switch using a method call, delegate, Action< or EventHandler< Implementation of SyncInformation class I currently don't care about the implementation of the SyncInformation class. I am mainly focused on the OnSyncProgress method and how to call the SyncInformation methods. So my questions are: What is the most efficient approach? What is the most in-efficient approach? Is there a better way than using a switch in OnSyncProgress?

    I'm trying to write a query to give me the total number of users for each customer per day. Here is what I have so far, which for each customer/day combination is giving the total number of user dimension entries without splitting them up by customer/day. WITH MEMBER [Measures].[MyUserCount] AS COUNT(Descendants([User].CurrentMember, [User].[User Name]), INCLUDEEMPTY) SELECT NON EMPTY CrossJoin([Date].[Date].Members, [Customer].[Customer Name].Members) ON ROWS, {[Measures].[MyUserCount]} on COLUMNS FROM [Users]

  • Finding all CLASSPATH resources matching a pattern

    - by binil
    I want to read a bunch of text files, by loading them as resources using the context classloader. URL url = Thread.currentThread() .getContextClassloader() .getResource("folder/foo.txt"); Is there some way to get a list of resources whose names match a given pattern? For eg: URL[] matchingUrls = someLibrary.getMatchingResources("folder/*.txt"); Libraries like Spring can scan the classpath to find classes with a given annotation, so I am wondering if there something similar to load a bunch of resources.

  • Is there a way to listen for changes in an MySQL database table using Java and JDBC?

    - by adrian7
    I have a number of users which are logged in at a time in my desktop application. They are working on the same table (create, read, update, delete data) so I have to update their views, to reflect changes, every few seconds - currently I am thinking to use a different thread to do that. I am using the MySQL database engine. Is there a way, using JDBC, to listen for changes on a specific table in the database and triggering a Java method only when changes are made?

    I have a forum whereby links to a thread looks like http://www.website.com/comments.php?topic_id=1 How can I make it look like this http://www.website.com/1046302/some-link-desc#12154109 so that when such links are given out, the user is taken directly to that particular comment. I'm particular about the #12154109 . The other part of the URL /1046302/some-link-desc is achieved through .htaccess configuration.

  • organizing unit test

    - by soulmerge
    I have found several conventions to housekeeping unit tests in a project and I'm not sure which approach would be suitable for our next PHP project. I am trying to find the best convention to encourage easy development and accessibility of the tests when reviewing the source code. I would be very interested in your experience/opinion regarding each: One folder for productive code, another for unit tests: This separates unit tests from the logic files of the project. This separation of concerns is as much a nuisance as it is an advantage: Someone looking into the source code of the project will - so I suppose - either browse the implementation or the unit tests (or more commonly: the implementation only). The advantage of unit tests being another viewpoint to your classes is lost - those two viewpoints are just too far apart IMO. Annotated test methods: Any modern unit testing framework I know allows developers to create dedicated test methods, annotating them (@test) and embedding them in the project code. The big drawback I see here is that the project files get cluttered. Even if these methods are separated using a comment header (like UNIT TESTS below this line) it just bloats the class unnecessarily. Test files within the same folders as the implementation files: Our file naming convention dictates that PHP files containing classes (one class per file) should end with .class.php. I could imagine that putting unit tests regarding a class file into another one ending on .test.php would render the tests much more present to other developers without tainting the class. Although it bloats the project folders, instead of the implementation files, this is my favorite so far, but I have my doubts: I would think others have come up with this already, and discarded this option for some reason (i.e. I have not seen a java project with the files Foo.java and FooTest.java within the same folder.) Maybe it's because java developers make heavier use of IDEs that allow them easier access to the tests, whereas in PHP no big editors have emerged (like eclipse for java) - many devs I know use vim/emacs or similar editors with little support for PHP development per se. What is your experience with any of these unit test placements? Do you have another convention I haven't listed here? Or am I just overrating unit test accessibility to reviewing developers?

  • Swing and handling threads

    - by James P.
    There's a couple questions here on StackOverflow on the subject of threading with the Swing api but things still aren't clear. What is the issue with the EDT, what is the proper way to initiate a Thread with Swing and in what cases should it be used? P.S: Any sources in terms of good practises would be appreciated.

  • background worker in asp.net

    - by vbNewbie
    I migrate my winforms crawler app to a asp.net web app and would like to know how to implement the background worker thread that I use for very long searches? Another posting mentioned asynchronous pages but I am not sure if this would work or how to apply it. The search function that would run can sometimes run for a few days and I would like the user to have the option to perform other functions still. Can this happen?

  • Delphi component you can't live without?

    - by Warren P
    Most delphi developers have a list of delphi components they wouldn't live without. Not including anything that ships with Delphi (standard VCL or included third-party software like Rave or Indy), what are the components you can't live without, be they commercial or open-source? I will refrain from adding my own answers unless this becomes a community wiki. One component name, or product name, per answer please. Please vote up on components and do not post duplicates.

  • How to get a stable, snappy UI using threads?

    - by Thomas Ahle
    I recently watching this video on Google Chrome with great interest. It explains that Google Chrome uses one thread for IO, one for opening files and one for intermodule communication. I think I may be able to use something similar for my own - currently quite messy - application. I wondered if there were any good articles on best-practices or patterns for such threaded divisions of tasks?

  • Why is my BeginInvoke method not async?

    - by Petr
    Hi, In order to avoid freezing of GUI, I wanted to run method connecting to DB asynchronously. Therefore I have written this: DelegatLoginu dl = ConnectDB; IAsyncResult ar=dl.BeginInvoke(null, null); bool result = (bool)dl.EndInvoke(ar); But it is still freezing and I do not understand why - I though BeginInvoke assures that method it references is run in another thread. Thank you!

  • STL container to pop() by priority?

    - by Pirate for Profit
    I'm writing a thread-pool for Qt as QRunnable doesn't handle event loops in new threads. Not too familiar with STL, what would be the best way to pop() something by priority? Priority should probably be a property of MyRunnable imo, but I can always give that info to an STL container when adding the runnable to the queue.

  • Replace Entity Framework object

    - by majkinetor
    In MVC app, I am having this big object that is used in classic view/edit/create pattern. When user edits the object I save it as: public bool SetMyObject(MyObject newObject) { MyObject current = GetObjectById(newObject.Id); current.Prop1 = newObject.Prop1 ... current.PropN = newObject.PropN db.SaveChanges(); } MyObject is pretty big so I am wondering is there any better way to do this, not involving per-property assignments. For instance something along the lines db.MyObject.UpdateObject(current, tnew). Ty.

    I am aware of this question, but it is a bit old now, and some of the answers seem outdated. Question: please write one answer per GUI you have used, including pros and cons (for example, as far as I can tell, with git gui, you can't manage the stash).
