• The benefits and hassles of moving entirely to a WPF Project

  - by Ben

  Hi, I have a project that i started as a WinForms application as that was the format i was confortable with at the time. I have since started dabbling in WPF an introduced some WPF UserControls (mainly grids) into my project and absolutely love them. The question i have is, is there any real advantage to me changing the UI Project of my solution into a purely WPF project, and get rid of any WinForms? I am fully aware that each format suits a certain environment, and you wouldnt be able to give a definitive answer without knowing more of the details, but i would like to know peoples opinions, and if anyone has done a silimar thing of converting an existing WinForms App into a WPF frontend, and any observations they made in doing so. Thanks

• NHibernate Query object collection issue

  - by Mahesh

  Hi, I am new to NHibernate and need some information regarding the internal working of the engine: I have a table called Student and the design is as follows: RollNo Name City Postcode and there are 5 more columns like this. I have School class and mappings associated with it. I am querying RollNo and Name using session as given below: IQuery query = session.CreateQuery("SELECT RollNo,Name FROM Student); Executing query.List resulting in error because the query is returning object[][]. Now, I changed the query as given below: IQuery query = session.CreateQuery("FROM Student); Executing query.List on this query yeilds the desired results. But, the results contain more data than I want. Could you please let me know the query to which I can get RollNo and Name from Student and castable as Student collection. Thanks, Mahesh

• where to get a wordpress theme review

  - by Ayrton

  Hi I'm currently developing some Wordpress templates and I wanted to get a review by a (semi)professional. I already know quite a bit about Wordpress,CSS, & JS but I was always a lone wolf without any guidance that's why I was wondering where I could find someone (trustworthy) to do something like this and how much he should charge me. It's pure about the code (the PHP, JS & the CSS) I would like to have a review on about (nothing design related). A link to the Wordpress theme I'm talking about: http://demo.wpmonk.com Yours truthfully

• ASP.NET UserControl Inheritence

  - by Craig

  I have a UserControl that is working fine. It is declared like this. public partial class DynamicList : System.Web.UI.UserControl { protected static BaseListController m_GenericListController = null; public DynamicList() { m_GenericListController = new GenericListController(this); } } Now I want to override this control so I can change some of the properties. I have created a class like this. public partial class JobRunningList : DynamicList { public JobRunningList() { m_GenericListController = new JobListController(this); (m_GenericListController as GenericListController).ModuleId = 14; } } It appears that the controls in the DynamicList are not getting created though when I use the JobRunningList control now causing predictably bad results. The DynamicList UserControl has a ListView on it and a few other controls. It appears these are not created when using the JobRunningList. Is there any secret to this?

• Best jQuery/Prototype book for complex ajax?

  - by Burton Kent

  I've been working on a complex app with one main dashboard. I don't particularly like the design because it tries to do too much on one page. So the lead developer thought it would be a good idea to use ajax - because the page is so big. Refreshing part of it is far faster than loading it again. Problem is there's several ways data can be used. Adding items Editing rows Performing actions on selected rows (selected using a checkbox) Changing single items (like location, phone) My problem is making GENERALIZABLE ajax code that can operate on the data in a div, using class names to assemble the proper information for the ajax call. I did pretty well, but can't help but want to see if there's a better way to do it.

• Hide segment in URL but give code access to hidden segment

  - by Brandon Durham

  I'm using Structure and have a "Supernav" page with multiple children that will make up the supernav for the site. I thought this would be a nice way to have all pages on the site accessible to the client via one location: the Structure UI. If you visit any of the child pages in the "supernav" group the URL comes out like this: http://website.com/supernav/prospective-students I'd love to be able to remove the supernav segment of those URLs so that it ends up being: http://website.com/prospective-students I don't even want the supernav segment to appear in the status bar when you hover over these links on the page. Is this possible? With CodeIgniter this comes down to a simple routing rule, but I don't know if that's an option with EE. Appreciate any help I can get!

• debug jquery selector

  - by Fabian

  Hi, I am looking for a way to debug what a jquery selector returns/selected. I tried to use toString() but that only returns [object Object]. What I am actually trying to do is to attach a callback to radio buttons. And on click on one of the buttons I want to submit the enclosing form. Therefore I try to do something like this: $(".rating").stars({ cancelShow: false, callback: function(ui, type, value, event) { $(this).closest('form').ajaxSubmit(); } }); But unfortunately just nothing happens. Thanks a lot, Fabian

• How to organize Enterprise scale Composite Applications (CAG)

  - by David

  All QuickStarts and RI examples in the CAG documentation are good but I lack the more Enterprise scale examples. Let's say we have 40+ modules, each containing a Proxy,Facade,PresentationModel,Model and Views. Each module also makes calls to a Module-specific WCF service which is to be hosted in IIS or in a stand-alone console host. Our approach have been to include the UI-module, service-module and related tests into one solution so they can be developed and tested separately from other modules. My problem is how the hosting of the services should be done when the services are in separate modules and how to actually run the separate module together with the rest of the application-modules when I press F5. Is there a best practise for this? I guess it has been done before?

• "The left hand side of an assignment must be a variable" due to extra parentheses

  - by polygenelubricants

  I know why the following code doesn't compile: public class Main { public static void main(String args[]) { main((null)); // this is fine! (main(null)); // this is NOT! } } What I'm wondering is why my compiler (javac 1.6.0_17, Windows version) is complaining "The left hand side of an assignment must be a variable". I'd expect something like "Don't put parentheses around a method invokation, dummy!", instead. So why is the compiler making a totally unhelpful complaint about something that is blatantly irrelevant? Is this the result of an ambiguity in the grammar? A bug in the compiler? If it's the former, could you design a language such that a compiler would never be so off-base about a syntax error like this?

• Python Framework for small website

  - by mvid

  I am planning a small, simple website to showcase myself as an engineer. My preferred language is Python and I hope to use it to create my website. My pages will be mostly static, with some database stored posts/links. The site will be simple, but I would like to have freedom in how it operates. I plan on using CSS/JS for the design, so I really just need an easy way to throw a small amount of content around. Some frameworks I have come across: Flask cherry.py Pinax Are there any suggestions? Does anyone have any experience with Python on small/hobby websites?

• WPF Dragging causes renderer to stop

  - by Cameron MacFarland

  I'm having a problem with my WPF app, where any sort of drag operation stops the UI from updating. The issue seems periodic, as in, the item drags, stops, drags again, stops, etc. in 2 second intervals. It's affecting all controls, including scroll bars. If checked this question as well as this one, and it doesn't seem to be caused by window transparencies. I'm running Win7 x64 with .NET 3.5sp1. Does anyone know what might be causing this, or a way of figuring out what might be causing this?

• Figuring out if overflow:auto would have been triggered on a div

  - by jerrygarciuh

  Hi folks, // Major edit, sorry in bed with back pain, screwed up post One of the ad agencies I code for had me set up an alternate scrolling solution because you know how designers hate things that just work but aren't beautiful. The scrolling solution is applied to divs with overflow:hidden and uses jQuery's scrollTo(). So, this is married in places to their CMS. What I have not been able to sort yet is how to hide the scrolling UI when overflow:auto would not have been triggered by the CMS content. The divs have set heights and widths. Can i detect hidden content? Or measure the div contents' height? Any ideas? TIA JG

• Java, filling arrays, and inheritance

  - by Arvanem

  Hi folks, I think I'm running into an inheritance conceptual wall with my Java arrays. I'm kind of new to Java so please tell me if I have things upside down. In essence, I want to do three things: Create a runnersArray with the attributes of my Runners class. Fill my runnersArray using my GenerateObjects method of my GenerateObjects class. Access the contents of my filled runnersArray in my Evaluating method of my Evaluating class. The problem seems to be that runnersArray is not visible to the methods in steps 2 and 3 above, but their classes (due to design reasons) cannot inherit or extend Runners class. Thanks in advance for any suggestions. Here are some code snippets showing what I'm trying to do: public class Runners extends Party { Runners[] runnersArray = new Runners[5]; } and public class GenerateObject extends /* certain parent class */ { public GenerateObject (int arrayNum) { runnersArray[arrayNum] = /* certain Runners attributes */; } } and public class Evaluating extends /*certain parent class*/ { public Evaluating (int arrayNum) { System.out.println(/* String cast attribute of runnersArray[arrayNum]*/; } }

• How should I manage data in an 2D vector based animation program?

  - by shadow

  I've been trying to design a program that makes 2D animations and then uses the ffmpeg library to create the video for possible use in tv and movies. The problem is when I think about how to manage the data in the application I can only think of two ways, I don't think either of them will work out very well. One is to use an SQlite database, but it seems like it will be difficult to save, especially if an artist puts 1000 things on screen. The other is to use something like linked lists, which would duplicate many features of the database and get complicated when dealing with things like points on a bezier curve and jumping to a frame and collecting all the objects that need to be drawn on that frame. Should I use one of these solutions, or is there something else that would be better? Currently planning to use C# for code.

• server side Adobe AIR apps

  - by Robbie

  This might sound like a really stupid question, but is there anyway to run an Adobe AIR application in a headless server side mode on a non-UI server (i.e. Linux)? I'm trying to build server side bots to interact with an API (grapevinetalk.com) and I want to use existing code to do that without having to re-write all the data munging etc for a new application. The application I'm trying to port is essentially a jQuery based AIR desktop app that I want to reuse for server side interactions. I've tried Rhino with envjs.com, but am having some issues so am looking at alternatives. Thanks Robbie

• Reverse engineer an ORM

  - by Oren Mazor

  Given a [mysql] database with a given schema, is it possible to generate an ORM interface for it? doesn't matter if its php, python or perl. in other words, I have a database and I have to ask it a few questions. while I could just craft a bunch of SQL queries (okay, several dozen), this is way more interesting to think about. is this a valid question, even? I have no design background with ORMs, but I've used a few (django's, symfony's, etc).

• How do I load the Oracle schema into memory instead of the hard drive?

  - by Andrew

  I have a certain web application that makes upwards of ~100 updates to an Oracle database in succession. This can take anywhere from 3-5 minutes, which sometimes causes the webpage to time out. A re-design of the application is scheduled soon but someone told me that there is a way to configure a "loader file" which loads the schema into memory and runs the transactions there instead of on the hard drive, supposedly improving speed by several orders of magnitude. I have tried to research this "loader file" but all I can find is information about the SQL* bulk data loader. Does anyone know what he's talking about? Is this really possible and is it a feasible quick fix or should I just wait until the application is re-designed?

• PHP Tag Cloud System

  - by deniz

  Hi, I am implementing a tag cloud system based on this recommendation. (However, I am not using foreign keys) I am allowing up to 25 tags. My question is, how can I handle editing on the items? I have this item adding/editing page: Title: Description: Tags: (example data) computer, book, web, design If someone edits an item details, do I need to delete all the tags from Item2Tag table first, then add the new elements? For instance, someone changed the data to this: Tags: (example data) computer, book, web, newspaper Do I need to delete all the tags from Item2Tag table, and then add these elements? It seems inefficient, but I could find a more efficient way. The other problem is with this way is, if someone edits description but does not change the tags box, I still need to delete all the elements from Item2Tag table and add the same element. I am not an experienced PHP coder, so could you suggest a better way to handle this? (pure PHP/MySQL solution is preferable) Thanks in advance,

• The type already contains a definition for 'Zehut'

• SubSonic: MySqlDataReader closes connection.

  - by SchlaWiener

  I am using SubSonic 2.1 and entcountered a problem while executing a Transaction with SharedDbConnectionScope and TransactionScope. The problem is that in the obj.Save() method I get an "The connection must be valid and open" exception I tracked down the problem to this line: // Loads a SubSonic ActiveRecord object User user = new User(User.Columns.Username, "John Doe"); in this Constructor of the User class a method "LoadParam" is called which eventually does if (rdr != null) rdr.Close(); It looks like the rdr.Close() implicitly closes my connection which is fine when using the AutomaticConnection. But during a transaction it is usally not a good idea to close the connection :-) My Question is if this is by design or if it's an error in the MySqlDataReader.

• How to improve my LDAP schema?

  - by asmaier

  Hello, I have a OpenLDAP Database and it holds some project objects that look like dn: cn=Proj1,ou=Project,ou=ua,dc=org cn: Proj1 objectClass: top objectClass: posixGroup member: 001ag member: 002ag System: ABEL System: PCx Budget: ABEL:1000000:0.3 Budget: PCx:300000:0.3 One can see that the Budget attribute is a ":"-separated string, where the first part holds the name of the system the budget is for, the second part holds some budget (which may change every month) and the last entry is a conversion factor for the budget of that system. Seeing this, I thought this is bad database design, since attribute values should always be atomic. But how can I improve that in LDAP, so that I can do a direct ldapsearch or a direct ldapmodify of the budget of System "ABEL" instead of writing a script, that will have to parse and split the ":"-separated string?

• WPF: Create a dialog / prompt

  - by stefan.at.wpf

  Hello, I need to create a Dialog / Prompt including TextBox for user input. My problem is, how to get the text after having confirmed the dialog? Usually I would make a class for this which would save the text in a property. However I want do design the Dialog using XAML. So I would somehow have to extent the XAML Code to save the content of the TextBox in a property - but I guess that's not possible with pure XAML. What would be the best way to realize what I'd like to do? How to build a dialog which can be defined from XAML but can still somehow return the input? Thanks for any hint!

• Wiki Database, is there one?

  - by Faiz

  I was searching the net for something like a wiki database, just like wikipedia but instead stores structured content, editable by users. What I was looking for was an online database accessible by everyone where people can design the schema and data with proper versioning of both schema and data. I couldn't find any such site. I am not sure if it is my search skills or if there really is no wiki database as of now. Does anyone out there know anything like this? I think there is a great potential for something like this. A possible example will be a website with a GUI for querying a MySQL DB where any website visitor can create DB objects and populate data.

• Displaying large file in JTextArea.

  - by Sathish Gopal

  Hi All, I'm currently working in Swing UI Assignment. This work involves showing large file content in JTextArea. The file size can be as large as 2 GB. My initial idea is to lazily load content from the file, say 1 MB of content will be shown to the user. As the user scrolls i will retrieve the next 1 MB of content to be shown. All these operation will be happening in background thread (Swing Worker). I looked at the JTextArea API, the method insert takes String and int(position of the insert) as the parameter. This will suffice, but i'm worried about performance, because the content (1 MB at a time) retrieved will have to be converted to String object. Is there any other work around or any other alternative/better solution for this.
