• Network Differences

  - by Chris

  I am busy working on a java app to run on blackberries but on some devices i am testing on, the code does not seem to be working and im having a hard time pinpointing where the problem lies. My question is: Could the problem with some phones working and not working have t odo with the type of network they are running on such GSM vs CDMA and would the code that stops working on some devices be in one of the following areas: 1) Listeners - such as MessageListener and Phone Listener 2) UI Objects - simple test labels and buttons 3) Connection to a web service using ksoap2

• jquery .find to get the text in a <li>

  - by Chris

  So I have a series of 2 nested ul's. When you click on the text (which is in an a tag) in the li, my page makes that editable and adds a save button. clicking the save button needs to give me back the new text inside that li and the id of that li. The id is not a problem. I'm trying to use jQuery's .find to select that anchor tag (which is successful) but i can't seem to get the text from it. Here is an example of the first list and it's sublists. <ul class='lists'> <li class='list1'> <a class='a list' id='list1'> List 1 Name</a> <img id='savelist1id' onClick="SaveName(this.parentNode.id)" src='save.jpg'> <ul class='list1subs'> <li class='sub1'> <a class='a sub' id='sub1id'> Sub 1 Name</a> <img id='savesub1id' onClick="SaveName(this.parentNode.id)" src='save.jpg'> </li> <li class='sub3'> <a class='a sub' id='sub2id'> Sub 2 Name</a> <img id='savesub2id' onClick="SaveName(this.parentNode.id)" src='save.jpg'> </li> <li class='sub2'> <a class='a sub' id='sub3id'> Sub 3 Name</a> <img id='savesub3id' onClick="SaveName(this.parentNode.id)" src='save.jpg'> </li> </ul> </li> </ul> Here's the code for identifying which save button you clicked. function SaveName(parentid){ $('li').find('a').each(function(){ if (this.id == parentid){ alert(this.id+' '+this.text) } } }); I am wanting this.text to show me the text inside the anchor tags. Help, please?

• Yahoo Astra flash component error BaseScrollPane not found

  - by Chris

  I'm trying to use the Astra library from Yahoo but I'm getting an error saying the base class BaseScrollPane is not found. It appears to be imported from fl.containers.BaseScrollPane, which leads me to believe it should be a part of the base flash 10 library and therefore should be available, but it appears to be missing. Is this part of a separate package from somewhere? Update: For what it's worth, I found the actual class files in the Configuration/Component Source folder on my hard drive, but adding that to the class path (as well as the Components directory) did no good. I ended up fixing the issue by dragging a scroll pane component to the stage from the Components window and then deleting it, but I'm not sure what exactly that action changed that made it work, and would like to know for future reference.

• How to generate a PDF of dynamic HTML content?

  - by chris Frisina

  I am trying to be able to allow users to generate content dynamically, and have that information be in a , and then allow that specific to be exportable to a pdf. I have got Joomla up and running (with the appropriate mySQL and ANT) locally with the Web2PDF extension, but how would I get those running on my domain (hosted by Dreamhost). Are there any other approaches you might recommend. The content is generated by JS and JQuery, and formatted with CSS and HTML. Other considerations: Web2PDF generates a PDF on the entire content, (pulling the entire page's HTML, not just the specific <div>.

• PHP attempting to make JavaScript friendly timestamp, failing, returns 1.34899651119E+12

  - by chris

  Well, not sure whats going on. I have been trying to follow by examples I have found here on stack, on google, even an answer someone gave me a week+ ago, which unfortunately I wasn't able to test until today. Anyway I am attempting to generate a javascript friendly timestamp via php so I can get my times synced up. The best logic I could find overall was something dealing with microtime. However that doesn't seem to work as expected, not even in the slightest. Right now I am using microtime(true)*1000; and am getting 1.34899651119E+12 for the result. Did I some how manage to mess up that one tiny line of code, Im not sure.

• How to provide an API client with 1,000,000 database results?

  - by Chris Dutrow

  What is a good way to provide an API client with 1,000,000 database results? We are cureently using PostgreSQL. A few suggested methods: Paging using Cursors Paging using random numbers ( Add "GREATER THAN ORDER BY " to each query ) Save information to a file and let the client download it Iterate through results, then POST the data to the client server Return only keys to the client, then let the client request the objects from Cloud files like Amazon S3 (still may require paging just to get the file names ). What haven't I thought of that is stupidly simple and way better than any of these options?

• Android Notepadv1 Tutorial - Persistent mNoteNumber?

  - by Chris L.

  So I did the Notepadv1 tutorial. It worked great. No problems. I would however like some explanation on why the mNoteNumber remembers the last number of the item I created. So the class starts as follows: public class Notepadv1 extends ListActivity { private int mNoteNumber = 1; That's fine, I understand that. The only other time the mNoteNumber variable is used is when you add an item it creates a note with that number and then increments it to the next number as follows: private void createNote() { String noteName = "Note " + mNoteNumber++; Those are the only two references to the variable mNoteNumber. When I press the Home button and then reopen the app, I add a new note but instead of adding a second "Note 1" it remembers that the last note I added as "Note 3" so it makes "Note 4". So I don't get it. Does Java/Android remember the last state of variables? If anyone could give me some explanation that would be great THANKS!

• HTML5 elements working in Chrome but not Safari or Firefox?

  - by Chris Armstrong

  Hi, I'm using the HTML5 elements and in a project i'm working on (see it here) and the css seems to be working fine in Chrome. However, it doesn't appear to be working in Safari or Firefox (I haven't tested IE, but I'd imagine it's the same), and the page layout is all over the place. Any ideas why this may be? I know Firefox and Safari both support these elements, and Safari is webkit-based like Chrome, so I can't figure out what the problem is.

Thanks. P.s. How would you get the box to update to those settings - is a refresh or the programming equivalent of ipconfig /renew required?

• Why do some .NET Framework classes not use Generics when they could?

  - by Chris Dwyer

  Example: System.Web.Security.MembershipCollection implements IEnumerable and not IEnumberable<T>. Why doesn't it implement the latter, when it seems that it would be better (e.g. use LINQ)? Or, is it not necessarily better?

• Conditional compilation hackery in C# - is there a way to pull this off?

  - by Chris

  I have an internal API that I would like others to reference in their projects as a compiled DLL. When it's a standalone project that's referenced, I use conditional compilation (#if statements) to switch behavior of a key web service class depending on compilation symbols. The problem is, once an assembly is generated, it appears that it's locked into whatever the compilation symbols were when it was originally compiled - for instance, if this assembly is compiled with DEBUG and is referenced by another project, even if the other project is built as RELEASE, the assembly still acts as if it was in DEBUG as it doesn't need recompilation. That makes sense, just giving some background. Now I'm trying to work around that so I can switch the assembly's behavior by some other means, such as scanning the app/web config file for a switch. The problem is, some of the assembly's code I was switching between are attributes on methods, for example: #if PRODUCTION [SoapDocumentMethodAttribute("https://prodServer/Service_Test", RequestNamespace = "https://prodServer", ResponseNamespace = "https://prodServer")] #else [SoapDocumentMethodAttribute("https://devServer/Service_Test", RequestNamespace = "https://devServer", ResponseNamespace = "https://devServer")] #endif public string Service_Test() { // test service } Though there might be some syntactical sugar that allows me to flip between two attributes of the same type in another fashion, I don't know it. Any ideas? The alternative method would be to reference the entire project instead of the assembly, but I'd rather stick with just referencing the compiled DLL if I can. I'm also completely open to a whole new approach to solve the problem if that's what it takes.

• Problems deploying Sinatra app to staging environment

  - by chris

  I have a small Sinatra app with both a staging and production environment on a single server with running Nginx. To deploy I am using Capistrano and capistrano-ext to easily deploy to different locations. The problem that the staging environment always runs with the production configuration specified within the app.rb file. configure :staging do # staging settings set :foo, "bar" end configure :production do # prod settings set :foo, "rab" end I have come to the conclusion that the capistrano :environment variable within the deploy.rb file doesn't config Sinatra in any way. I have also tried setting the ENV["RACK_ENV"] to "staging" to no avail. config/deploy/staging.rb server "10.10.100.16", :app, :web, :db, :primary => true set :deploy_to, "/var/www/staging.my_app" set :environment, "staging" set :env, "staging" ENV["RACK_ENV"] = "staging" Any ideas?

• How do I serve a large file using Pylons?

  - by Chris R

  I am writing a Pylons-based download gateway. The gateway's client will address files by ID: /file_gw/download/1 Internally, the file itself is accessed via HTTP from an internal file server: http://internal-srv/path/to/file_1.content The files may be quite large, so I want to stream the content. I store metadata about the file in a StoredFile model object: class StoredFile(Base): id = Column(Integer, primary_key=True) name = Column(String) size = Column(Integer) content_type = Column(String) url = Column(String) Given this, what's the best (ie: most architecturally-sound, performant, et al) way to write my file_gw controller?

• javascript prototype problem

  - by Chris Tosswill

  So I have a rather basic javascript problem which I have been slamming my head into a wall over for awhile: <div class='alist'> <ul> <li class='group_1'> An Item </li> <li class='group_1'> An Item </li> <li class='group_2'> An Item </li> </ul> </div> <div class='alist'> <ul> <li class='group_1'> An Item </li> <li class='group_1'> An Item </li> <li class='group_2'> An Item </li> </ul> </div> <script> function toggle_item( num ){ $$( 'li.group_' + num ).invoke('toggle'); } </script> Basically, I need to create a sweeper that sets the div to display:none if all the li are display:none. I think it would start like: function sweep(){ $$('div.alist').each( function( s ) { ar = s.down().children }); } Any suggestions for good tutorials would be welcome as well

  - by Chris

  SSIS ignoramus needing help! the situation: a temp table is populated from an excel file, which has been known to change formats at random times, that is owned by a different group. a lookup need to be performed on the temp table, tableA, to populate tableB with valid data. if the lookup results in 0 rows being returned, an email should be sent and the existing data in tableB should remain untouched. If the lookup results in a number of valid rows 0, tableB should have all rows deleted and the new records from the lookup on tableA inserted. question: what would be the best way to check if there are any valid rows and perform the appropriate action(s), depending on my results? Thanks!

• Creating a Month Dropdown in C# ASP.NET MVC

  - by Chris M

  This method seems stupid and a bit heavy; is there a more optimal way of creating the same thing (its for an MVC View Dropdown) private List<KeyValuePair<int, string>> getMonthListDD { get { var dDur = new List<KeyValuePair<int, string>>(); dDur.Add(new KeyValuePair<int, string>(1, "January")); dDur.Add(new KeyValuePair<int, string>(2, "Febuary")); dDur.Add(new KeyValuePair<int, string>(3, "March")); dDur.Add(new KeyValuePair<int, string>(4, "April")); dDur.Add(new KeyValuePair<int, string>(5, "May")); dDur.Add(new KeyValuePair<int, string>(6, "June")); dDur.Add(new KeyValuePair<int, string>(7, "July")); dDur.Add(new KeyValuePair<int, string>(8, "August")); dDur.Add(new KeyValuePair<int, string>(9, "September")); dDur.Add(new KeyValuePair<int, string>(10, "October")); dDur.Add(new KeyValuePair<int, string>(11, "November")); dDur.Add(new KeyValuePair<int, string>(12, "December")); return dDur; } }

• Setting PATH in Makefile run by eclipse

  I have a Makefile which runs fine from a bash shell, but fails to run from Eclipse. This is because the path I am setting in my .bash_profile is not getting used. What is the best way of making this happen? Is there somewhere else I could put the path, to make sure it is invoked in non-interactive shells (which is I assume how eclipse is running make)?

• Is there a way to find TOP X records with grouped data?

  - by Chris Simmons

  I'm working with a Sybase 12.5 server and I have a table defined as such: CREATE TABLE SomeTable( [GroupID] [int] NOT NULL, [DateStamp] [datetime] NOT NULL, [SomeName] varchar(100), PRIMARY KEY CLUSTERED (GroupID,DateStamp) ) I want to be able to list, per [GroupID], only the latest X records by [DateStamp]. The kicker is X 1, so plain old MAX() won't cut it. I'm assuming there's a wonderfully nasty way to do this with cursors and what-not, but I'm wondering if there is a simpler way without that stuff. I know I'm missing something blatantly obvious and I'm gonna kick myself for not getting it, but .... I'm not getting it. Please help. Is there a way to find TOP X records, but with grouped data?
