• Is there a good Open Source xml ide?

  - by Paul Butcher

  I've looked around, and I'm surprised that I can't find an Open Source equivalent to Oxygen or XMLSpy. i.e. A rich XML editor with support for diverse types of validation, XSLT debugging and profiling, and all the other extra bits that make it more than just a text editor with syntax highlighting. I've seen a few (like Jaxe), that that offer different ways to edit xml documents, but nothing that rolls it all up into an IDE-like application. I'm sure this means I've missed some very worthy project. Can anyone point me towards such a thing?

• Routing WCF Traffic Based on URI Domain Requested

  - by Ian Patrick Hughes

  Is there a way to route traffic to a target WCF service file based on the URL domain requested? Basically, I have a single WCF RESTful services project with 3 service files offering different endpoints. It's hosted on a single IIS6 site looking for multiple host header values on port 80. I want to route traffic to different services files whether the requester is asking for www.site1.com, www.site2.com, or www.site3.com. Seems like the sort of thing I would use a global.asax or HTTP Handler for, but I am not sure since this is a regular WCF Service Application. Even though I am on IIS6 for this project, I don't mind using a URL re-writer and wildcard mapping, if I have to. I have admin rights on the balanced servers where this will reside, I just want to know if there is a common/best practice before I start hacking my way around this.

• What is the difference between remote procedure call and web service

  - by xiao

  Is there any clear definition about RPC and Web Service? A quick wikipedia search shows: RPC: Remote procedure call (RPC) is an Inter-process communication technology that allows a computer program to cause a subroutine or procedure to execute in another address space (commonly on another computer on a shared network) without the programmer explicitly coding the details for this remote interaction. Web Service: Web services are typically application programming interfaces (API) or web APIs that are accessed via Hypertext Transfer Protocol and executed on a remote system hosting the requested services. Web services tend to fall into one of two camps: Big Web Services[1] and RESTful Web Services. I am not quite clear what the real difference between the two things. It seems that one thing could belongs to RPC and is kind of web service at the same time. Is Web Service a higher level representation of RPC?

• Compile Qt Project To Run On A Linux System

  - by ForgiveMeI'mAN00b

  I have a Qt project. It uses the cross platform libraries SDL, OpenGL and FLTK. I want to be able to compile the project so that it can run on a Linux computer. I'm looking at a bunch of articles I have seen so far two ways to do this. Use a cross compiler, which seems to me a rather complicated thing to setup and compile with, or, the other options, is to compile the project simply on a Linux computer, simply the Linux version of Qt creator/SDK. My question is, If I have a Qt project that uses only cross platform libraries, then is creating a Windows version easy as compiling it in Qt/Windows, and creating the Linux version as easy as doing it in Qt/Linux? PS. Please don't ask/complain about why I didn't just try to see if it works myself, I don't have any Linux OS's installed on my computer right now, and I don't want to risk going into the trouble of installing a whole new OS just to have it not work in the end.

• 400 bad request when calling a WCF service via jQuery/Ajax in a IIS7 server

  This is what the IIS log says: 2012-12-12 16:35:44 W3SVC1 server001 76.229.32.109 POST /Dashboard/svc/RunJob.svc/RunJob/ExecuteJob - 80 - 76.229.32.109 HTTP/1.1 Mozilla/4.0+(compatible;+MSIE+8.0;+Windows+NT+6.0;+WOW64;+Trident/4.0;+SLCC1;+.NET+CLR+2.0.50727;+.NET+CLR+3.0.30729;+.NET+CLR+3.5.30729) ASP.NET_SessionId=poxpqp45rv2m3tuflzckix45 http ://server001/Dashboard/RunJob.aspx server001 400 0 0 2444 1423 1934 I have maxReceivedMessageSize set to a very high number.

• Membership systems for MVC4 that support RavenDB

  - by brad oyler

  I create a lot of quick "proof of concept" MVC apps and I actually found the SimpleMembership provider that shipped with the MVC4 templates to be very handy since it gets me up and running with user registration & OAuth in a matter of minutes. But...I've started to use RavenDb (on RavenHQ for a lot for my projects). So, I starting trying to implement my own "custom membership provider" based on the ExtendedMembershipProvider and while doing that I realized that didn't make much sense. I later stumbled upon 2 interesting projects that try to solve this exact problem: WorldDomination.Web.Auth: https://github.com/PureKrome/WorldDomination.Web.Authentication MemFlex: https://github.com/OdeToCode/Memflex Both are pretty interesting recent efforts and was wondering if these are the only ones being built right now. I'm essentially looking for nuget pkg that I can drop into a MVC4 app, connect to my RavenDb and be done. I'm willing to build this thing but don't want to duplicate any efforts that are already in motion. Thx!

• Why do I get HTTP Code 414 on one network but not another?

  - by Stephen Darlington

  I have an otherwise working iPhone program. A recent change means that it generates some very long URLs (over 4000 characters sometimes) which I know isn't a great idea and I know how to fix -- that's not what I'm asking here. The curious thing is that when I make the connection using a 3G network (Vodafone UK) I get this HTTP "414 Request-URI Too Long" error but when I connect using my local WiFi connection it works just fine. Why would I get different results using different types of network? Could they be routing requests to different servers depending on where the connection originates? Or is there something else at stake here? The corollary questions relate to how common this is. Is it likely to happen whenever I use a cell network or just some networks?

• Displaying "broken" sprites?

  - by Roman

  I'm quite new to the world of 2D-Engines. I figured out how to load images and display those as sprites and stuff, but theres one question that bugs me. For instance, when a "rocket" hits an object it will deal damage to it and leave a crater behind. I'd like to have the crater shown on that object. That would require "skipping" some of the pixels of that image when rendering, doesn't it? My question is, how would you do such a thing? What data strcture would you use to save this? How to display a "broken" sprite?

• Rendering "partial" pages in ASP.Net? (without the <html> and such)

  - by Earlz

  Hello, I am trying to make use of jQueryUI AJAX tabs in my ASP.Net Webforms project. I have come up against a wall though. For AJAX, you must render only a partial page(no <html> and such elements) by an external URL. How would you best do this in ASP.Net? aspx files require things like a <html> and <head> tag so those wouldn't work so the only thing that comes to mind is using cumbersome ashx files. Am I just over thinking this? Is there an easier way?

• Where to handle fatal exceptions

  - by Stephen Swensen

  I am considering a design where all fatal exceptions will be handled using a custom UncaughtExceptionHandler in a Swing application. This will include unanticipated RuntimeExceptions but also custom exceptions which are thrown when critical resources are unavailable or otherwise fail (e.g. a settings file not found, or a server communication error). The UncaughtExceptionHandler will do different things depending on the specific custom exception (and one thing for all the unanticipated), but in all cases the application will show the user an error message and exit. The alternative would be to keep the UncaughtExceptionHandler for all unanticipated exceptions, but handle all other fatal scenarios close to their origin. Is the design I'm considering sound, or should I use the alternative?

• Anonymous functions in C#

  - by Maxim Gershkovich

  The following syntax is valid VB.NET code Dim myCollection As New List(Of Stock) myCollection.Add(New Stock(Guid.NewGuid, "Item1")) myCollection.Add(New Stock(Guid.NewGuid, "Item2")) Dim res As List(Of Stock) = myCollection.FindAll(Function(stock As Stock) As Boolean If stock.Description = "Item2" Then Return True End If Return False End Function) How can I accomplish the same thing in C#? I have tried... myCollection.FindAll(bool delegate(Stock stock) { if (blah blah) { } }); But it appears I have somehow structured it incorrectly as I get the following error. "Error 1 Invalid expression term 'bool'"

• Multiple Payment options within the same order

  - by Rob Y

  I have a requirement to be able to accept different forms of payment within the same order - ie not just the usual credit card or paypal for the whole thing, but perhaps paypal for one item, cheque for another. I know this sounds quite crazy, but there is a good business reason for the requirement so I can't just push back. The best way I can think of implementing it at the moment is to have kind of a hub page, where you can "launch off" into multiple flows for each of the payments by opening new windows. I can't figure out a way of doing this in a linear flow as for example you can't guarantee that a user will come back from paypal, so you'd then lose the user completely. Is there a neater way of doing this that anyone can think of, or can anyone point me to an example of a site that does somethign similar for inspiration?

• How to unit test configs

  - by ForeverDebugging

  We're working with some very large config files which contain lots of Unity and WCF configuration. When we open some of these configs in the SVC config editor or even try to open a web application using these configs, we recieve errors showing any typos or errors. E.g. a WCF binding is invalid or does not exist etc, or a configuration section does not exist, two endding tags, etc. Is there some way to "valid" a config through a unit test? So there's one less thing which could go wrong when the application is moved into a new environment.

• How to Map a table with another lookup table using JPA?

  - by Sameer Malhotra

  Hi, I have two tables: 1) Application(int appid, int statusid, String appname, String appcity with getter and Setter methods) 2) App_Status(int statusid,String statusDescription with setter and getter methods) I want to map Application table with App_Status so that I don't have to query separately App_Status table in order to get the statusDescription. One thing I have to careful is that no matter what (Insert,update or delete) to the Application table the App_Status table should be unaffected means its a read only table which is maintained by the DBA internally and used only for lookup table. I am using JPA annotations so please suggest how to handle this.

• Online webcam chat. Free server and easy-to-implement client?

  - by Oskar Kjellin

  I have a client requesting that his users can use their webcams to talk to each other. From what I've understood the main thing to use for this is Flash. However as I have not written flash I would like to have something really easy to implement. Of course preferrably free (or trial). The idea of this is that everything but the chat alone is in .net. So the users will not use flash until they are actaully going to talk to each other. So there is no use for rooms here. I've been looking into silverlight some as well. But it seems like silverlight does not offer streaming between users..? I know this question has been asked many times here. But I could not find a suitable answer which is why I post a new question.

• Good IM/Chat solution for pasting code

  - by Matt Miller

  We've got several distributed developers working together on a couple of projects. We've been using Skype to host chats with all the developers, and it works okay except for one thing: It REALLY mangles any code we copy and paste into the chats -- especially the whitespace in Python. This question has tons of opinions about chat clients & servers, but no one has much to say about pasting in code. (http://stackoverflow.com/questions/36415/best-chat-im-tool-for-developers) Is anybody out there using a chat or im client that handles source code really well?

• Magento - Programmatically added products don't show up

  - by Lucasmus

  I am trying to import products using a custom made import profile. Here I set some values on the product and then save it, like this: $product = Mage::getModel('catalog/product'); $data = array(); // Inbetween I fill $data with some values $product->addData($data); $product->save(); However, the products do show up in the admin, but do not show up on the frontend (I did add them to categories). The odd thing is, they do appear on the frontend once I open them in the admin and save them again (without modifying anything). Am I forgetting something, or some value that is somehow set by that action? I tried to rebuild all indices in the backend and to clear the cache, but this does not work, contrary to Magento API: Rebuild Indexes after adding new products.

• Android and PHP - Do I need to use sessions?

  - by jtnire

  I have created an Android App that communicates with a PHP web server. They both send JSON to each other. My App is almost finished, however there is one thing left to do: authentication. Since the user's username and password will be stored in Android SharedPreferences, is there any need to use PHP sessions, given that the user won't need to enter the username/password at every request? Since I can just send the username and password in the HTTP POST header for every request, and that I will be using SSL, is this sufficient? I guess I could add an extra field in the header called 'random' that just adds a random value, just to use as a salt so that the encrypted SSL payload will be different everytime. The reason why I don't want to use sessions is that my Android App would either have to handle cookies, or managed the storage of the session ID. If there are some serious cons to using my method above, then I'm more than happy to use sessions, however all advice is appreciated. Thanks

• Referencing surrogate key

  - by Arman

  I have a table that has an autoincrement surrogate key. I want to use it as a foreign key of my other table. The thing is, I cant figure out how I can reference it to that table, because it is nearly impossible to determine what I have to reference(the actual value of the surrogate key). Please be noted that what I am trying to do is adding a tuple/record through my program(outside the dbms). The process is: Add a new record in Table1 and generate an autoincrement key. Update Add a new record in Table2 and reference its foreign key to the primary key of Table1. Update My question is : HOW do I store the foreign key if I didnt know what is it?

• generate Grid from template

  - by theXs

  Howdy, I've got another question regarding phone 7... I want to generate a couple of Grids in a stackpanel - since they all have the same layout I thought it would be a great idea to use DataTemplates ... But then I found that the GRID Object has no "DataTemplate" Property and now I'm kinda stuck ... the template which I use is the following: <DataTemplate x:Key="Speise"> <Grid> <TextBlock Height="36" Margin="8,43,104,0" TextWrapping="Wrap" Text="TextBlock" VerticalAlignment="Top"/> <TextBlock HorizontalAlignment="Right" Height="36" Margin="0,44,8,0" TextWrapping="Wrap" Text="TextBlock" VerticalAlignment="Top" Width="92"/> </Grid> </DataTemplate> The way I now thought of creating my objects is: Grid blubber = (Grid)this.Resources["Speise"]; But that is not working ... I think it's again a really short thing, but I have no clue of how to google for it :(

• Handle Enter Key on Website (ASP and VB)

  - by Andrew

  So I have a website with multiple asp controls. When I press enter inside by login form, the search function runs because it's the first thing found on the page. How would I handle the enter button so that when the active textbox is for the login form, the loginbutton code actually runs rather than the searchbutton. One last problem is that the login controls are inside a loginview so the hierarchy shows that the asp:textbox and asp:button for logging in are inside 3 tags like so: <loginview> <login> <logintemplate> //controls are here. </logintemplate> </login> Just a note that all controls are asp and that all code is prefered in VB. Thanks

• TextMate/Macfusion combo for mounting projects over SSH

  - by Sam Lee

  Here is my workflow: I use Macfusion to mount a server over SSH, and then edit the root directory of the project in TextMate (using mate /Volumes/server/projectdir). I have a plug in installed that disables refreshing on refresh. This works ALMOST perfectly--the only thing I have problems with is "Find in Project": it's REALLY slow. Has anyone run into this problem before and been able to find any solutions? Currently I go to terminal when I have to do a search, but it would be great to be able to do it in TextMate. Thanks!

• What are some useful SQL statements that should be known by all developers who may touch the Back en

  - by Jian Lin

  What are some useful SQL statements that should be known by all developers who may touch the Back end side of the project? (Update: just like in algorithm, we know there are sorting problems, shuffling problems, and we know some solutions to them. This question is aiming at the same thing). For example, ones I can think of are: Get a list of Employees and their boss. Or one with the employee's salary greater than the boss. (Self-join) Get a list of the most popular Classes registered by students, from the greatest number to the smallest. (Count, group by, order by) Get a list of Classes that are not registered by any students. (Outer join and check whether the match is NULL, or by Get from Classes table, all ClassIDs which are NOT IN (a subquery to get all ClassIDs from the Registrations table)) Are there some SQL statements that should be under the sleeve of all developers that might touch back end data?

• How can I show the "Upload" tab in CKEditor?

  - by Hermet

  Hi guys, I've checked the CKEditor developer documentation and also some solved questions in here about this editor but couldn't find one which helped me. The thing is, I have set up CKEditor and when I get into the images dialog I can't see any "Upload" tab. I am trying to set up a custom file uploader, and according to the documentation is something like this: <script type="text/javascript"> CKEDITOR.replace( 'cuerpo', { filebrowserBrowseUrl : '/imgs/explorador.php', filebrowserUploadUrl : '/imgs/subirImagenes.php' }); </script> Thank you, and apologies for my English.

• How can I by using the FormHelper ,or some other method, render an image link that runs javascript w

  Background: I want to render this: <a href="javascript:myfunction('Somevar')"><img src="some.png" width="20" height="20" border="0" /></a> in a cakephp app. Note: this link is not associated with a model at all, it's just part of a form going off-site. I'm unsure of how to proceed: I've seen this on the cakephp site, but with all that goes on in cake, I'm not sure about the whole javascript calling business. What's the best way to create such a thing?
