• C# Stream Reader adding \n to XML

  - by Terry

  I use the StreamReader class to obtain XML for my GeoCoding process from Google. StreamReader srGeoCode = new StreamReader(WebRequest.Create(Url).GetResponse().GetResponseStream()); String GeoCodeXml = srGeoCode.ReadToEnd(); XmlDocument XmlDoc = new XmlDocument(); GeoCode oGeoCode = new GeoCode(); XmlDoc.Load(GeoCodeXml); I get XML back but it adds \n and other extras to the XML <?xml version=\"1.0\" encoding=\"UTF-8\" ?>\n<kml xmlns=\"http://earth.google.com/kml/2.0\"><Response>\n <name> I have the same code in VB and it does not do this. I can successfully GeoCode my information using the VB version of this console app. Is there a reason the C# version adds this extra data to the XML that I retrieve back? I am trying my best to convert everything over to C#. I enjoy coding in it over VB.

• Java,Tomcat,Sessions - JSessionId disappears

  - by Bob

  Hi, I'm having a problem with java sessions. I'm developing a simple web app, where I have to use sessions and session attributes. Everything is fine until I close my browser. When I close my browser the JSessionId disappears. Here's my code: request.getSession().setMaxInactiveInterval(30*60); //it's 30 minutes request.getSession().setAttribute("someinteger", 10); It works great, but when I shut down the browser, and reopen it I can't find the jsessionId (before I closed the browser I could find it in the 'localhost' section). The strange thing is I can still find the "someinteger" cookie. What is the problem? What am I doing wrong? I'm using this, too: link text, and it shows that JSESSIONID cookie expires : "SESSION", and "someinteger" expires in 30 minutes Thanks in advance.

• Ajax Get Request works fine when requested in browser, but gets 302 in iframe. What could be the reason for this?

  - by Vlad Nicula

  I am working on a web app that makes several ajax requests at startup. The applications works fine when run individually. When running it into a iframe, one of the ajax requests returns a 302 Found HTTP status. I'm sure I'm hitting the same url with both the browser and the iframe. The application that creates the frame is on a different domain and port. What could be causing this? Out of 5 get requests to the same server, only one (the third) gets a 302.

• UINavigationController from UIViewController

  - by 4thSpace

  I currently have this workflow in a tab based app: Tab1 loads... ViewOne : UIViewController >> PickerView : UIViewController >> DetailView : UIViewController "" means loads based on user action. I'd like navigation bars on PickerView and DetailView. PickerView just needs a cancel button in the top left of its nav bar. DetailView needs the normal navbar back button. I already have PickerView's nav bar wired up through IB and working. I'm not sure what to do with PickerView's nav bar. PickerView is also loaded from Tab2, who's main view starts as a UINavigationController. PickerView's nav bar works fine in that case. ViewOne should not have a navigation bar. Any ideas?

• Mac OS : creating a background periodic simple script

  - by Julien

  Hi folks ! I have a friend who wants something quite easy : he has a mac, and he would like a very simple script/app that runs in the background. The goal is to replace a file every 5 minutes with one downloaded from the internet. I would also like a menu on the top bar (like the clock on Mac Os, the wifi, the sound, Dropbox,...) What would be the easiest way to do that ? Objective C ? AppleScript ? Do you guys have any inspiration for that ? Thanks a lot Julien

• Questions and considerations to ask client for designing a database

  - by Julia

  Hi guys! so as title says, I would like to hear your advices what are the most important questions to consider and ask end-users before designing database for their application. We are to make database-oriented app, with special attenion to pay on db security (access control, encryption, integrity, backups)... Database will also keep some personal information about people, which is considered sensitive by law regulations, so security must be good. I worked on school projects with databases, but this is first time working "in real world", where this db security has real implications. So I found some advices and questions to ask on internet, but here I always get best ones. All help appreciated! Thank you!

• 'NSInvalidArgumentException' UIButton IBAction Error

  - by Graeme

  Hi, I have a button in a view which refuses to work. I've got in working in a blank, default view application from X-Code, but in none of my applications will it work, instead it gives me the following error. Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '* -[UIViewController showVicInfo:]: unrecognized selector sent to instance 0x3c084f0' The debugger isn't any help either. I've made sure that I hook up the button to the file's owner (not the other way around) as well. Below is the code for the action. And I know it's not the alert view, because the breakpoint doesn't even reach there. about.h @interface about : UIViewController { } -(IBAction)showInfo:(id)sender; about.m -(IBAction)showVicInfo:(id)sender { UIAlertView *myAlert = [[UIAlertView alloc] initWithTitle:@"No Internet Connection" message:@"You require an internet connection via WiFi or cellular network for iFirelert to work." delegate:self cancelButtonTitle:@"OK, thanks" otherButtonTitles:nil]; [myAlert show]; [myAlert release]; }

• SMO missing dll on a clients

  - by Dale

  I've created an app that connects remotely to SQL Server 2008. SQL connections work and all traditional oCommand.ExecuteNonQuery(), work great! But my SMO class using server.ConnectionContext.ExecuteNonQuery(scriptfile); ERROR: missing batch parsing.dll . I can't install these independent utils on a client machines, and then take them all off when done: as suggested by: http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=228de03f-3b5a-428a-923f-58a033d316e1 Since my bulk-inserts are large memory hogs containing complete tables, I wrote the tables to a temptable.sql files and used SQLCMD Util and later switch too SMO and I have the same problem. Neither of these can be leveraged on the client's PCs . Any suggestion? thanks :-)

• OutOfMemoryException - out of ideas

  - by Captain Comic

  Hi I have a net Windows service that is constantly throwing OutOfMemoryException. The service has two builds for x86 and x64 Windows. However on x64 it consumes a lot more memory. I have tried profiling it with various memory profilers. But I cannot get a clue what the problem is. The diagnosis - service consumes lot of VMSize. Also I tried to look at performance counters (perfmon.exe). What I can see is that heap size is growing and %GC time is 19%. My application has threads and locking objects, DB connections and WCF interface. See first app in list The link to picture with performance counters view http://s006.radikal.ru/i215/1003/0b/ddb3d6c80809.jpg

• Ruby/Rails Audio Conversion Plugins?

  - by coneybeare

  I am looking for a good gem/plugin to convert user-uploaded audio files to different formats. One format in particular that I am interested in is converting to Apple .caf with ima4 compression for inclusion in an iPhone app. I have been using afconvert on my mac for this so far, but I need to do it on my linux box, server-side. Ideally, I would be able to work into paperclip. As an additional solution, ffmpeg could work, but I have not seen any .caf options for it. Anybody know of one?

• Monodevelop: `Waiting for debugger to connect...`

  - by Nicolas Raoul

  I am trying to debug this Mono desktop software in Monodevelop. I imported the SLN file, ran Build all with success, but when I press the Debug button I get this popup that stays waiting forever saying Waiting for debugger to connect...: The output says: User assembly '/home/nico/src/SparkleShare/SparkleShare/bin/SparkleShare.exe' is missing. Debugger will now debug all code, not just user code. Am I doing something wrong? Monodevelop 2.8.6.3 on Ubuntu 2012.04. Nothing special appears on the console with monodevelop -v -v -v. When I press Run instead of Debug, the app crashes immediately saying The application exited with code: 255, but I need Debug to find where the problem is. Note: It is not the same problem as this question, which is about MonoTouch waiting for a phone simulator... the suggestions over there are about the simulator or updating XCode... no simulator nor XCode here.

• Listening and firing events with Javascript and maybe jQuery

  - by at

  In my Javascript and Flex applications, users often perform actions that I want other Javascript code on the page to listen for. For example, if someone adds a friend. I want my Javascript app to then call something like triggerEvent("addedFriend", name);. Then any other code that was listening for the "addedFriend" event will get called along with the name. Is there a built-in Javascript mechanism for handling events? I'm ok with using jQuery for this too and I know jQuery makes extensive use of events. But with jQuery, it seems that its event mechanism is all based around elements. As I understand, you have to tie a custom event to an element. I guess I can do that to a dummy element, but my need has nothing to do with DOM elements on a webpage. Should I just implement this event mechanism myself?

• Record AVAudioPlayer output using AVAudioRecorder

  - by Kieran

  In my app the user plays a sound by pressing a button. There are several buttons which can be played simultaneously. The sounds are played using AVAudioPlayer instances. I want to record the output of these instances using AVAudioRecorder. I have set it all up and a file is created and records but when I play it back it does not play any sound. It is just a silent file the length of the recording. Does anyone know if there is a setting I am missing with AVAudioPlayer or AVAudioRecorder? Thanks

• jquery json null when using localhost

  - by Eeyore

  I am trying to load json generated by my django app. It works when I save the json output and load it from a static file. However, when I make a call to a server it returns null. JSON {"users": [ { "id": 1, "name": "arnold" }, { "id": 2, "name": "frankie" } ]} Ajax call $.ajax({ url: "http://localhost:8000/json", //vs. json.js dataType: 'json', type: 'get', timeout: 20000, error: function() { alert("error"); }, beforeSend: function() { alert("beforeSend"); }, complete: function() { alert("complete"); }, success: function(data) { alert(data.users[0].name); } }); view.py return HttpResponse(simplejson.dumps(data), content_type = 'application/json; charset=utf8')

• Adding a header view to a UIWebView similar to Safari and Articles

  - by MrMage

  I'd like to add a header view to an UIWebView similar to the address/search bar in MobileSafari and the excellent Articles.app by Sophia Teutschler. More precisely, I'd like to create a "pull to fix orientation" view above a UIWebView, just like in Articles. Articles does use a UIWebView, so it seems to be possible. Is there a way to accomplish this without having to embed the UIWebView into a UIScrollView and updating its size all the time, as described in this article? Apparently, I do need the scrolling events to have the "pull to fix orientation" behave accordingly.

• Send failed from rails server to download in the browser

  - by Markus

  Hi everybody, I have a web application which has some multimedia files stored in a user protected area. To make this files available to logged in customers, I consider using the x-sendfile plugin. x_send_file(path, :type => 'application/pdf') It is just strange that every time I run this function a empty file gets sent to the browser download. I checked the path which is correct (app fails if I change it to a inexistent file). Actually if I use the rails internal send_file method, the same error occurs... Any help is appreciated! Markus

• Python questions from beginner

  - by ChrisC

  I'm thinking about rewriting an MS Access db I wrote years ago into a stand-alone Python app. Other than a college class called "Intro to C++" (console only, with OOP concepts) and the Access db itself, I have no experience, so I need to ask if the basis for my decision to go with Python is correct. Is it true that: 1) Python is relatively easy to pick up? 2) Python apps can run as "portable" (ie from one directory, no registry needs, nothing needs to be pre-installed on a Windows PC) as long as I use an embedded db?

• Is it an MD5 digest in this Python script?

  - by brilliant

  Hello, I am trying to understand this simple hashlib code in Python that has been given to me the other day on "Stackoverflow": import hashlib m = hashlib.md5() m.update("Nobody inspects") m.update(" the spammish repetition here") m.digest() '\xbbd\x9c\x83\xdd\x1e\xa5\xc9\xd9\xde\xc9\xa1\x8d\xf0\xff\xe9' m.digest_size 16 m.block_size 64 print m I thought that "print m" would show me the MD5 digest of the phrase: "Nobody inspects the spammish repetition here", but as a result I got this line on my local host: <md5 HASH object @ 01806220> Strange, when I refreshed the page, I got another line: <md5 HASH object @ 018062E0> and every time when I refresh it, I get another value: md5 HASH object @ 017F8AE0 md5 HASH object @ 01806220 md5 HASH object @ 01806360 md5 HASH object @ 01806400 md5 HASH object @ 01806220 Why is it so? I guess, what I have in each line flowing "@" is not really a digest. Then, what is it? And how can I display MD5 digest here in this code? My python version is Python 2.5 and the framework I am currently using is webapp (I have downloaded it together with SDK from "Google App Engine")

• C# SqlBulkCopy and Data Entities

  - by KP

  Guys, My current project consists of 3 standard layers: data, business, and presentation. I would like to use data entities for all my data access needs. Part of the functionality of the app will that it will need to copy all data within a flat file into a database. The file is not so big so I can use SqlBulkCopy. I have found several articles regarding the usage of SqlBulkCopy class in .NET. However, all the articles are using DataTables to move data back and forth. Is there a way to use data entities along with SqlBulkCopy or will I have to use DataTables?

• ColdFusion code parser?

  - by Kip

  I'm trying to create an app to search my company's ColdFusion codebase. I'd like to be able to do intelligent searches, for example: find where a function is defined (and not hit everywhere the function is called). In order to do this, I'd need to parse the ColdFusion code to identify things like function declarations, function calls, database queries, etc. I've looked into using lex and yacc, but I've never used them before and the learning curve seems very steep. I'm hoping there is something already out there that I could use. My other option is a mess of difficult-to-maintain regex-spaghetti code, which I want to avoid.

• How to casue a CppUnit test to fail - from C?

  - by mawg

  I'd like to have an equivalent to CPPUNIT_ASSERT, CPPUNIT_ASSERT_MESSAGE or `CPPUNIT_FAIL' which I can call from some common C code. Our code is a mix of C and C++. Some older apps and those with specific requirements are coded in C and most, especially newer, are coded in C++. However, a lot of project-agnostic, common code, such as memory buffer pools, debug tracing, etc are coded in C. When testing a C++ app in CppUnit, I'd to be able to sprinkle some ASSSERT()s which would cause any running CppUnit test to fail. Maye something like: if testing if running in debugger (Eclipse) then asm("int3"); // stop the debugger, even if no breakpoint at this line else if running CppUnit test - fail the test and move on to next else trace to log file Most of that can be run by wrapping a macro around a few #ifdefs, but I am not sure how I would cause a CppUni test to fail from C code. Can it be done?

• Can't read from aspnet_client folder for crystal reports

  - by Hank Allen

  I created a little ASP .Net app to run Crystal Reports. It runs fine from VS 2008 but not when deployed to IIS on Windows 7. The toolbar images are not rendered. The problem seems to be I can't read from the aspnet_client folder even though I've made into a virtual directory. I can't even read images I put in there just to see if the folder can be read from an ASP page. I also made sure the IIS user can read from there. I'm stumped.

• NSURLConnection still calls delegate AFTER cancel method has been called

  - by Shizam

  Hi All, Having a problem with NSURLConnection, if I create a NSURLConnection and call [connection connectionWithRequest] let it load a little then call [connection cancel] most of the time that works fine. However occasionally even after I call [connection cancel] the connection's delegate still gets called (which crashes the app). Googling around it looks like the problem here is a race condition in the runloop, I cancel the connection and release the delegate but before the runloop cycles it calls the delegate functions - crash. Is there a way for me to, after I call [connection cancel] confirm the connection has actually canceled? Even a crappy while() loop will do :(

• Amazon S3 Change file download name

  - by Daveo

  I have files stored on S3 with a GUID as the key name. I am using a pre signed URL to download as per S3 REST API I store the original file name in my own Database. When a user clicks to download a file from my web application I want to return their original file name, but currently all they get is a GUID. How can I achieve this? My web app is in salesforce so I do not have much control to do response.redirects all download the file to the web server then rename it due to governor limitations. Is there some HTML redirect, meta refresh, Javascript I can use? Is there some way to change the download file name for S3 (the only thing I can think of is coping the object to a new name, downloading it, then deleting it). I want to avoid creating a bucket per user as we will have a lot of users and still no guarantee each file with in each bucket will have a unique name Any other solutions?

• Thin, Sinatra, and intercepting static file request to do CAS authentication

  - by Kenny Peng

  I'm using the casrack-the-authenticator gem for CAS authentication. My server is running Thin on top of Sinatra. I've gotten the CAS authentication bit working, but I'm not sure how to tell Rack to intercept "/index.html" requests to confirm the CAS login, and if the user is not allowed to view the page, return a HTTP 403 response instead of serving the actual page. Does anyone have experience with this? Thanks. My app: class Foo < Sinatra::Base enable :sessions set :public, "public" use CasrackTheAuthenticator::Simple, :cas_server => "https://my.cas_server.com" use CasrackTheAuthenticator::RequireCAS end My rackup file: require 'foo' use Rack::CommonLogger use Rack::Lint run Foo
