• Android: Send arbitrary objects within Activities?

  - by Sebastian

  I have read some question here but I didn't find a solution. I have read about Parcelable, Intents, and sharing specific data within Activities from the android dev docs (both dev guide and reference). Here's the scenario: I have one ListActivity that fills in an object parsing an xml file, it shows a list of values, and when clicked I want to return the object that represents the item clicked to the activity that has called it, for then, call another activity with this object. I read on how to implement Parcelable but seems not being the way. Implementing Parcelable receives a Parcel for the constructor and then reads the values from it (or at least that was what I understood). This makes no sense for me and I can't see how to implement basing on that issue. I build the object parsing the xml file, not having a Parcel. I appreciate some clarifications on this, regards.

• Which collation should I use to store these country names in MySQL?

  - by morpheous

  I am trying to store a list of countries in a mySQL database. I am having problems storing (non English) names like these: São Tomé and Príncipe República de El Salvador They are stored with strange characters in the db, (and therefore output strangely in my HTML pages). I have tried using different combinations of collations for the database and the MySQL connection collation: The "obvious" setting was to use utf8_unicode_ci for both the databse and the connection information. To my utter surprise, that did not solve the problem. Does anyone know how to resolve this issue?

• Getting sourcecontrol on stored procedures

  - by Steffen

  First off the technical stuff: We're using VS 2008 pro and running a MS SQL 2008 server. For sourcecontrol we use Subversion. We'd really like to keep our stored procedures in subversion, so we can tell what was changed, when and so forth. However in order for this to work, it has to be seamless, otherwise the developers are just going to forget getting the procedures included in their commits. So are there any good solutions for this ? I'm certain we can't be the only company with this issue :-)

• Matching First Alphanumeric Character skipping (The |An? )

  - by TheLizardKing

  I have a list of artists, albums and tracks that I want to sort using the first letter of their respective name. The issue arrives when I want to ignore "The ", "A ", "An " and other various non-alphanumeric characters (Talking to you "Weird Al" Yankovic and [dialog]). Django has a nice start '^(An?|The) +' but I want to ignore those and a few others of my choice. I am doing this in Django, using a MySQL db with utf8_bin collation. EDIT Well my fault for not mentioning this but the database I am accessing is pretty much ready only. It's created and maintained by Amarok and I can't alter it without a whole mess of issues. That being said the artist table has The Chemical Brothers listed as The Chemical Brothers so I think I am stuck here. It probably will be slow but that's not so much of a concern for me as it's a personal project.

  Hi, I have an issue when reading properties from a dependent project. I have a core project, and my application has a dependency on it. under classpath of core, it has file core.properties. and my application need to read this property file, but it couldn't. It requires the core.properties in my classpath of my application, instead of core. Is there an solution for that? One solution in my mind is that when I build my application.war, can I explictly declare that I want the core dependency be exploded? Thanks for help!

• Faking user interaction on CMS

  - by Leocer

  I'm working with a CMS and need to import data to it using typical html forms. The data itself is in csv files with one page per row. Such is the CMS that importing directly to db isn't possible due to the complexity of the design. It's pretty important that i "fake" usual user interaction because the CMS does a lot of background work that's crucial for the import. Basically, for each row in the csv file, I need to copy a csv column to a html textfield, or select a checkbox, or click a certain button. One major issue is mapping the data in the csv to actions in the CMS. So if one column contains the string 'foobar' is really means "set the firstName dropdown widget to 'foobar'". Is there a tool to automate this? I´ve been looking at AutoHotKey, Selendium, Web-Harvester and many other tools but I'm not convinced they are the correct tools. The main problem is being able to interact with the html pages in a easy way.

  There is 20px margin/padding below the catmenuconatiner (second navigation bar). This is only showing in firefox and chrome not in IE 6+ Here is the page: www.fish-and-web.blogspot.com Another problem related to the same issue is between the comments.

Again, this is only showing in Firefox and Chrome not in IE6+ Here is the comment page: http://fish-and-web.blogspot.com/2010/05/alfa-romeo-9c_24.html It'd be great if someone comes along and guide me in the right direction. I have been working on this for hours and I just cannot get it to work. Just so you know that the page is hosted on blogger. Thank you.

• Using Property Builtin with GAE Datastore's Model

  - by ejel

  I want to make attributes of GAE Model properties. The reason is for cases like to turn the value into uppercase before storing it. For a plain Python class, I would do something like: Foo(db.Model): def get_attr(self): return self.something def set_attr(self, value): self.something = value.upper() if value != None else None attr = property(get_attr, set_attr) However, GAE Datastore have their own concept of Property class, I looked into the documentation and it seems that I could override get_value_for_datastore(model_instance) to achieve my goal. Nevertheless, I don't know what model_instance is and how to extract the corresponding field from it. Is overriding GAE Property classes the right way to provides getter/setter-like functionality? If so, how to do it? Added: One potential issue of overriding get_value_for_datastore that I think of is it might not get called before the object was put into datastore. Hence getting the attribute before storing the object would yield an incorrect value.

• how to retain one million of simultanous TCP connections?

  - by cow

  i am to design a server that needs to serve millions of clients that are simultaneously connected with the server via TCP. the data traffic between the server and the clients may be sparse. so bandwidth issue can be ignored. one important requirement is that whenever the server needs to send data to any client it can use the existing TCP connection instead of opening a new connection toward the client (because client can be behind a firewall). does anybody know how to do it and what hardware/software is needed (at the least cost)? thanks in advance for any suggestion.

• Visual Studio 2008 profiler analysis - missing time

  - by Scott Vercuski

  I ran the Visual Studio 2008 profiler against my ASP.NET application and came up with the following result set. CURRENT FUNCTION TIME (msec) ---------------------------------------------------|-------------- Data.GetItem(params) | 10,158.12 ---------------------------------------------------|-------------- Functions that were called by Data.GetItem(params) TIME (msec) ---------------------------------------------------|-------------- Model.GetSubItem(params) | 0.83 Model.GetSubItem2(params) | 0.77 Model.GetSubItem3(params) | 0.76 etc. The issue I'm facing is that the sum of the Functions called by Data.GetItem(params) do not sum up to the 10,158.12 msec total. This would lead me to believe that the bulk of the time is actually spent executing the code within that method. My question is ... does Visual Studio provide a way to analyze the method itself so I can see which sections of code are taking the longest? if it does not are there any recommended tools to do this? or should I start writing my own timing scripts? Thank you

• ProgrammingError: (1146, "Table 'test_<DB>.<TABLE>' doesn't exist") when running unit test for Djang

  - by abigblackman

  I'm running a unit test using the Django framework and get this error. Running the actual code does not have this problem, running the unit tests creates a test database on the fly so I suspect the issue lies there. The code that throws the error looks like this member = Member.objects.get(email=email_address) and the model looks like class Member(models.Model): member_id = models.IntegerField(primary_key=True) created_on = models.DateTimeField(editable=False, default=datetime.datetime.utcnow()) flags = models.IntegerField(default=0) email = models.CharField(max_length=150, blank=True) phone = models.CharField(max_length=150, blank=True) country_iso = models.CharField(max_length=6, blank=True) location_id = models.IntegerField(null=True, blank=True) facebook_uid = models.IntegerField(null=True, blank=True) utc_offset = models.IntegerField(null=True, blank=True) tokens = models.CharField(max_length=3000, blank=True) class Meta: db_table = u'member' there's nothing too odd there i can see. the user running the tests has the same permissions to the database server as the user that runs the website where else can I look to see what's going wrong, why is this table not being created?

• Counting distinct and duplicate attribute values in an array

  - by keruilin

  I have an array of users that's sorted in descending order based on total_points. I need to find the rank of each user in that array. The issue is that more than one user can have the same total points and, thus, the same rank. For example, three users could be in 3rd place with 200 Points. Here's my current code: class Leader < ActiveRecord::Base def self.points_leaders all_leaders = all_points_leaders # returns array of users sorted by total_points in desc order all_leaders_with_rank = [] all_leaders.each do |user| rank = all_leaders.index(user)+1 all_leaders_with_rank << Ldr.new(rank, user) # Ldr is a Struct end return all_leaders_with_rank end end How must I modify the code so that the correct rank is returned, and not just the value of the index position?

• debugging on bsd using gdb or similar tootls

  - by agent.smith

  I have started using freebsd lately and realized gdb does not support remote debugging on it. Whenever, I try to do remote debugging using gdbserver, I run into SIGSEGV crashes and error message says can’t find definition of “r_debug_state”. Has anyone ever experienced this and solved it? Statically compiled single threaded programs can be compiled using gdbserver. However, other than that it is mostly looking difficult to use. Let me know if anyone knows any other tools to do remote application debugging on bsd or how to fix the issue. (I am on x64 freebsd 9) Thanks

• .net example of using client certificates in web service call?

  - by Rory

  I'd like to use client certificates to verify the identity of administrative callers to my web service. Then I can issue certificates only to the people I want to call my web service and be pretty sure noone else can call it. This is in a very controlled scenario where only one or two people will get the client certificate, so distribution isn't a hard problem. This article provides a good example of how to call a web service using a client certificate. But how can I check details of the client certificate from within my web service? This old article talks about configuring IIS to do it, but I'd like to do it programmatically within my app. I think? thanks for any suggestions!

• Issuing native system commands in Scala

  - by Tony

  I want to issue a native system command from a Scala program, and perhaps trap the output. ("ls" comes to mind. There may be other ways to get directory information without issuing the command, but that's beside the point of my question.) It would correspond to os.system(...) in Python. I've looked in "Programming in Scala". I've looked in O'Reilly's "Programming Scala". I've Googled several combinations of terms. No luck yet. Can someone out there give me an example, or point me at a resource where I can find an example?

• How to Schedule a Process.Start in WPF

  - by Chi Chan

  I am trying to restart an application in WPF.

• SSRS default renderer strips html tags

  - by stackoverflowuser

  For TFS task work item, I copy a table from ms word 2003/2007 document and paste it into the description field (supports rich text). When the task item is saved, correct formatting is saved in TFS database table. But when the same data is displayed in a SSRs report (through report manager) the formatting is lost. Probably the ssrs rendering engine is stripping off the tags. I have the "HTML-Interpret HTML tags as styles" enabled for the report field. It will be of great help if someone can provide more information on this issue and how it can be handled. Thanks.

• Avoid multiple autocomplete calls by wrapping it with SetTimeOut

  - by pixelboy

  Here's my issue : using an autocomplete jQuery plugin, I'd like to avoid multiple ajax requests when user strikes his keynoard by surrounding the $('#query1').autocomplete({ serviceUrl:'/actions/autocomplete?population=salon', minChars:3, maxHeight:300, width:200, clearCache:true, onSelect: function(suggestions,data){ $(".btn1").attr("href", "${pageContext.request.contextPath}/actions/espaceClients?participantId=" + data) } }); with something like var search = false; $('#query1, #query2, #query3').keyup(function(){ if (!search){ search = true; } if (search) { search = false; autocompleteThem(); } }); A you can see, above code is stupid, but it kinda shows what i'm trying to do. In simple words, if user dosen't type anything else in a certain period of time, then you can call autocomplete. I hope i'm being clear, as my brains are a mess...

• SQL Server Query Editors - any that warn of number of rows to be changed?

  - by ciaranarcher

  We're using SQL Server 2000 Query Analyser, and one issue we have is that very occasionally, when a user is updating our live database, they insert the incorrect/no(!) where clause. I know, not good, but it happens. Are there any editors that will warn of the number of rows that might be changed (if that is even possible) or even a way to configure an editor, if it is connected to a certain database, to prompt for confirmation before the query is run? We have a way to recover our data in the cases where we run an incorrect query, but it takes time, and I'm just seeing if there are any ways to catch the error, or at least give the user a second chance. Thanks in advance.

• Make XStream ignore one specific private variable

  - by Tigraine

  Hi guys, I have a little problem with a class I am currently writing a save function for. I'm using XStream (com.thoughtworks.xstream) to serialize a class to XML using the DOMDriver. The class looks like this: public class World { private Configuration config; public World(Configuration config) { this.config = config; } } So, the issue here is that I do not want to serialize Configuration when serializing world, rather I'd like to give XStream a preconstructed Configuration instance when calling fromXml(). Problem here is mainly class design, Configuration holds a private reference to the GUI classes and therefore serializing Configuration means serializing the whole application completely with GUI etc.. And that's kind of bad. Is there a way to instruct XStream to not serialize the private field config, and upon load supply XStream with a configuration instance to use? greetings Daniel

• Sending JSON(jQuery) to PHP and decoding it

  - by dscher

  I can't for the life of me figure out what I'm doing wrong. It seems like it should be simple because I can't find anyone else with this issue but I can't figure out to send basic data via javascript(jQuery) to PHP and decode it. For the sake of simplicity, this is what I have: JAVASCRIPT var json_data = { "name" : "john doe" }; $.ajax({ type: "POST", url: "../bin/process.php", dataType: "json", data: json_data }); and my PHP FILE $arr = json_decode("json_data", true); $fp = fopen('data.txt', "w"); fwrite($fp, $arr['name']); fclose($fp); The file I'm writing ends up with nothing in it. If I do an: fwrite($fp, 'test'); I get a file with the word test in it but no matter what I do I don't get the json data I sent. Can someone please share a thorough example of A to Z. Thanks for any help.
