• Question on SyndicationItem - ASP.NET

  - by bobsmith123

  I am trying to understand how to use SyndicationItem to display feed which is RSS 2.0 or Atom compliant. What property of SyndicationItem gives me the entire description of the post. It appears that there is a Summary property but per MSDN, it gives only the Summary. Also I have noticed that in my RSS feed reader, some RSS feeds show only a few lines of description and I have to click and go to the website for the full post. But in some feeds, I can see the full post within the Feed Reader. Can someone explain how all this comes together? PS: My web page lets user enter a RSS feed address and I need to validate if the feed exists. If it does, I need to grab the last x items and show the feed's title and full description

• Executing AJAX scripts within an AJAX response

  - by KcYxA

  Hi there, I'm having trouble using AJAX page updates along with other AJAX scripts. During a normal page load, the AJAX scripts (picture scrolling and picture thumbnails) work fine. But when I update a page with AJAX, these scripts (usually loaded in the header of the initial page load) stop working. I am wondering if this is specific to these scripts and I need to look into them deeper to resolve/re-write or if I am missing something more generic in combining AJAX page updates with AJAX scripts the returned code relies on. Embedded javascript runs fine. Thanks for your ideas! PS: The scripts I am using are from www.dynamicdrive.com are: 1) stepcarousel (http://www.dynamicdrive.com/dynamicindex4/stepcarousel.htm) and 23) thumbnailviewer (http://www.dynamicdrive.com/dynamicindex4/thumbnail.htm) from the

• Play framework 1.x on Tomcat - httpOnly cookies

  - by aishwarya

  I'm setting application.session.httpOnly=true in the application.conf and generating a war file and deploying on tomcat. I still see the cookie generated as HttpOnly=No and it is editable. This is an issue with play 1.x running on tomcat 6 (i.e. servlet api 2.x). Apparently, http only flag for cookies was only introduced in servlet 3.0 and so is only available in tomcat 7+ has anybody identified a workaround for this so far (so I could have http only cookies for play 1.x on tomcat 6.x ) ? the httpOnly flag on context in tomcat only works for tomcat's jsessionid cookie... also, can I run a play 1.x app on servlet 3.0 ? PS: This was also posted on the play framework's google groups but we did not receive a response and so posting on SO.

• Anyone using Moles / Pex in production?

  - by dferraro

  Hi all, I did search the forum and did not find a similar question. I'm looking to make a final decision on our mocking framework of choice moving forward as a best practice - I've decided on Moq... untill I just recently discovered MS has finally created a mocking framework called Moles which seems to work similar to TypeMock via the profiler API sexyness etc.. There's a million 'NMock vs Moq vs TypeMock vs Rhino....' threads on here. But I never see Moles involved.In fact, I did not even know if its existence until a short time ago. Anyone using it? In Production? Anyone dump their old mocking framework for it, and if so, which one? How did it compare to ther mocking frameworks you've used? thanks.. ps, we are using VS2008 and are moving to 2010 shortly.

• Virtual Mice in C#

  - by jameshong

  Hi guys, Is there anything that we could do for implementing VIRTUAL MICE? I mean, I want to have multiple mice within the whole OS, but they must be all VIRTUAL (I'm not talking about the applications that serve multiple mice driver for PS/2 or USB mice or Microsoft's MultiPoint Mouse SDK.) It is like creating two objects: Mouse mouse1, mouse2; and using them like: mouse1.mouse_event(...); mouse2.mouse_event(...); having a CURSOR on the screen is NOT IMPORTANT. I only need the action (MOUSE DOWN, MOVE, UP for each but separated) and the important thing is that these VIRTUAL MICE should work together, at the same time, click or down-move action with different coordinates(x,y).

  Hi folks, I have an Activity (A) and a Service (S) which gets started by A like this: Intent i = new Intent(); i.putExtra("updateInterval", 10); i.setClassName("com.blah", "com.blah.S"); startService(i); A have a function like this one in A: public void someInfoArrived(Info i){...} Now I want to call A.someInfoArrived(i) from within S.

I found enough info about how to do that.

• Flex Overwriting my .HTML wrapper

  - by brett

  When I make changes to a Flex project and rerun the project, it seems that FlashBuilder4 rewrites my html wrapper that embeds the SWF. But I have additional javascript code in the html wrapper and don't want to keep losing my code. I had to re-write the code once and it was a pain in the neck. How do I stop it from re-writing the html. And the related question: how do I stop it from deleting the html during a clean? I basically need to exclude the html from its processing once it's been created the first time. P.S. I'm using Flash Builder 4, but I suppose it's the same in Flex Builder 3.

• WinAPI C - RunAsUser from REDMON_USER and REDMON_SESSIONID

  - by scriptmaster

  I installed a PostScript printer driver and have setup REDMON (redmonnt.dll) for redirecting postscript output to my program. In my rather simple c program I capture the data from STDIN and I am able to successfully save it into a .ps file. The file looks OK. However, I want to start gsview.exe for viewing the file. If I call ShellExecute it fails in Windows 7 because of permission issues. It seems that my program is called under a different user account (LOCAL SERVICE). So I am looking for a way to run gsview.exe under a specific username (the user who initiated the print job is available to me in a variable as REDMON_USER along with the SESSIONID as well. I am stuck (and my stack is overflowing =) What are the minimum WinAPI call I need to use to launch a program given a username and a sessionid? Any code examples in C/C++, .NET would be very helpful

• Get a tableview insertRowsAtIndexPaths to accept indexOfObject?

  - by Emil

  Hey. I have a code snippet that looks like this: [tableView beginUpdates]; [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationLeft]; [tableView insertRowsAtIndexPaths:[NSArray arrayWithObject:[array indexOfObject:[array objectAtIndex:indexPath.row]]] withRowAnimation:UITableViewRowAnimationLeft]; [tableView endUpdates]; [tableView reloadData]; It gets executed when a user clicks on an accessory. The first part is only there to provide a smooth animation, and does not really matter, as the tableView is reloaded milliseconds later, but as I said, it's there to provide an animation. It is supposed to move a selected object from its current indexPath to the value from an array at the same indexPath. Obviously, this code does not work, so I just want to know what can be done to fix it? PS: I get a warning when compiling, too. The usual "passing argument 1 of 'arrayWithObject:' makes pointer from integer without a cast..." (line 3)

• Removing all CALayer's sublayers

  - by radex

  Hi. I have trouble with deleting all layer's sublayers. I do this manually, but it's unwanted code clutter. I found many topics about this in google, but no answer. I tried to do something like this: for(CALayer *layer in rootLayer.sublayers) { [layer removeFromSublayer]; } but it didn't work. Also, i tried to clone rootLayer.sublayers into separate NSArray, but result was the same. Any ideas? regards, radex PS. sorry for my English. Edit: I thought it works now, but I was wrong. It works good with CALayers, but it doesn't work with CATextLayers. Any ideas?

• Functional Programming - Lots of emphasis on recursion, why?

  - by peakit

  I am getting introduced to Functional Programming [FP] (using Scala). One thing that is coming out from my initial learnings is that FPs rely heavily on recursion. And also it seems like, in pure FPs the only way to do iterative stuff is by writing recursive functions. And because of the heavy usage of recursion seems the next thing that FPs had to worry about were StackoverflowExceptions typically due to long winding recursive calls. This was tackled by introducing some optimizations (tail recursion related optimizations in maintenance of stackframes and @tailrec annotation from Scala v2.8 onwards) Can someone please enlighten me why recursion is so important to functional programming paradigm? Is there something in the specifications of functional programming languages which gets "violated" if we do stuff iteratively? If yes, then I am keen to know that as well. PS: Note that I am newbie to functional programming so feel free to point me to existing resources if they explain/answer my question. Also I do understand that Scala in particular provides support for doing iterative stuff as well.

• PHP + SQL Server or VB.NET + MySQL

  - by Muhammad Mussnoon

  Can someone suggest that out of the two mentioned (odd?) combinations, which is less odd, or in other words, is less trouble to work with + maintain. If it helps, the system is going to have two front-ends - one web application and one desktop application. The desktop application is going to be coded using VB.NET, and the web application in PHP. There's really no reason why the desktop application can't be replaced by a web application as well - except that one of the programmers seem to really want to code it in VB.... However, none of us have experience working with either of these pairs (you could easily call us n00bs), so we are a bit apprehensive to start. P.S. hosting service will be gotten from some provider and not be on the client's own server.

• Last byte missing when casting from varbinary to varchar

  - by xaxie

  I got the last byte losing when converting varbinary to varchar in some case. For example: DECLARE @binary varbinary(8000), @char varchar(8000) set @binary = 0x000082 set @char = CAST(@binary as varchar(8000)) select BinaryLength=DATALENGTH(@binary), CharLength=DATALENGTH(@char) The result is BinaryLength CharLength 3 2 The affected byte value is from 0x81 - 0xFE. The stranger thing is that if I use varchar(MAX) instead varchar(8000) when casting, there is no any problem. Could someone tell me the root cause of the issue? PS: I run the sql in MS SQL server 2008. Thanks!

• How to scale MySQL with multiple machines?

  - by erotsppa

  I have a web app running LAMP. We recently have an increase in load and is now looking at solutions to scale. Scaling apache is pretty easy we are just going to have multiple multiple machines hosting it and round robin the incoming traffic. However, each instance of apache will talk with MySQL and eventually MySQL will be overloaded. How to scale MySQL across multiple machines in this setup? I have already looked at this but specifically we need the updates from the DB available immediately so I don't think replication is a good strategy here? Also hopefully this can be done with minimal code change. PS. We have around a 1:1 read-write ratio.

• Searching for cluster computation framework

  - by petkov_d

  I have a library, written in C#, containing one method: Response CalculateSomething(Request); The execution time of this method is relatively large, and there are a lot of responses that should be processed. I want to use a "cluster", spread this DLL to different machines (nodes) in this "cluster" and write some controller that will distribute responses to the nodes. There should be mechanism that perevent losing task because of node crush, load balancing. Can someone suggest framework that addresses this issue? P.S. There is a framework Qizmt written in C# but I think MapReduce is not good for the above scenario

• Situations to prefer Apache Lucene over Solr?

  - by Karussell

  There are several advantages to use Solr (out-of-the-box facetting search, grouping, replication, http administration vs. luke, ...). Even if I embed a search-functionality in my Java application I could use SolrJ to avoid the HTTP trade-off when using Solr. So, when would you recommend to use "pure-Lucene"? Does it have a better performance or requires less RAM? Is it better unit-testable? PS: I am aware of this question.

• continuous music on website

  - by Patrick

  Hi all, I'm against it as I'm sure ALL of you are, but my client wants background music on their website. I'm very new to this, so was wondering how should I do that? I know I should use iframes, but what's the actual way of using them? eg: do I just create the home page with 2 frames (one for the music, one for the rest of the website), and then every time the user clicks on a link I can load the usual destination page - or should I update all pages in some way to make sure they are 'frames enabled'? Also, I do I style the frame to make sure it's hidden? thanks, Patrick ps please don't reopen the discussion about why background music is not good - I do know that and personally hate it. But the client is adamant and paying for it so... ;)

• Microsoft T-SQL to Oracle PL/SQL translation

  - by Michael Prewecki

  I've worked with T-SQL for years but i've just moved to an organisation that is going to require writing some Oracle stuff, probably just simple CRUD operations at least until I find my feet. I'm not going to be migrating databases from one to the other simply interacting with existing Oracle databases from an Application Development perspective. Is there are tool or utility available to easily translate T-SQL into PL/SQL, a keyword mapper is the sort of thing I'm looking for. P.S. I'm too lazy to RTFM, besides it's not going to be a big part of my role so I just want something to get me up to speed a little faster.

• google maps export driving directions to kml file - java geogoogle

  - by maiky

  Hi Sorry at first for my poor grammar. I am writing a program in Java using geogoogle (Google Geocoder Java API) http://geo-google.sourceforge.net/ I need from two specific points to get the walking directions between these points and also these info to be exported in a KML file. Do you know how can I do it from Java? Is there an API that I can use? Perhaps making a call from the java program to google and handle the result - but how can it be done? Thanks in advance. PS. Google gives this functionality as i saw here http://www.gringod.com/2008/02/26/save-google-maps-driving-directions/ but I need all these to be called from Java.

• Asp.Net 3.5 Routing to Webservice?

  - by Maushu

  I was looking for a way to route http://www.example.com/WebService.asmx to http://www.example.com/service/ using only the ASP.NET 3.5 Routing framework without needing to configure the IIS server. Until now I have done what most tutorials told me, added a reference to the routing assembly, configured stuff in the web.config, added this to the Global.asax: protected void Application_Start(object sender, EventArgs e) { RouteCollection routes = RouteTable.Routes; routes.Add( "WebService", new Route("service/{*Action}", new WebServiceRouteHandler()) ); } ...created this class: public class WebServiceRouteHandler : IRouteHandler { public IHttpHandler GetHttpHandler(RequestContext requestContext) { // What now? } } ...and the problem is right there, I don't know what to do. The tutorials and guides I've read use routing for pages, not webservices. Is this even possible? Ps: The route handler is working, I can visit /service/ and it throws the NotImplementedException I left in the GetHttpHandler method.

• [JS] XMLHttpRequest problem

  - by mcco

  I am trying to do "POST" with XMLHttpRequest in a firefox extension, and after that I try to get the "Location" header and open it in a new tab. For some reason, the XMLHttpRequest doesn't contain a location header. My code function web(url,request) { var http = new XMLHttpRequest(); http.open('POST',url,true); http.setRequestHeader('Content-Type','application/x-www-form-urlencoded'); http.onreadystatechange=function() { if(http.readyState == 2) { alert(http.getResponseHeader("Location")); } } http.send(request); } Also, if I change the alert to getAllResponseHeaders() to see all headers, I just don't see the location header there. If I try to spy on the request of the original site with Firebug, it does show me the location header in the response. Please help me resolve my issues. Thanks :) P.S. I'm also unable to open a link in new tab using window.open(url, this.window.title);, but as that's not directly related to the rest of this I'll post a separate question to ask about it.

• How can I use Moose with Test::Class?

  - by rassie

  I'm currently refactoring a test suite built up by a colleague and would like to use Test::Class[::Most] while doing so. As I started I figured out I could really use a couple of Moose roles to decouple code a little bit. However, it seems it's not quite possible -- I'm getting error messages like this one: Prototype mismatch: sub My::Test::Class::Base::blessed: none vs ($) at /usr/lib/perl5/vendor_perl/5.8.8/Sub/Exporter.pm line 896 So the question is: can I use Moose together with Test::Class and if so, how? PS: The code goes like this: package My::Test::Class::Base; use Moose; use Test::Class::Most; with 'My::Cool::Role'; has attr => ( ... );

• Regular expression in BASH

  - by Ryan

  Hello everyone, I was hoping someone could answer my quick question as I am going nuts! I have recently started learning regular expressions in my Java programming however am a little confused how to get certain features to work correctly directly in BASH. For example, the following code is not working as I think it should. echo 2222 | grep '2\{2\}' I am expecting it to return: 22 I have tried variations of it including: echo 2222 | grep '2{2}' echo 2222 | grep -P '2\{2\}' echo 2222 | grep -E '2\{2\}' However I am completely out of ideas. I'm sure this is a simple parameter / syntax fix and would love some help! P.S I've done tons of googling and every reference I find does not work in BASH; regex's can run on so many different platforms and engines =/
