• The Tab1.java from API Demo has exception.

  - by Kooper

  I don't know why.All my Tab programs have exception.Even from API Demo. Here is the code: package com.example.android.apis.view; import android.app.TabActivity; import android.os.Bundle; import android.widget.TabHost; import android.widget.TabHost.TabSpec; import android.view.LayoutInflater; import android.view.View; public class Tab1 extends TabActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); TabHost tabHost = getTabHost(); LayoutInflater.from(this).inflate(R.layout.main,tabHost.getTabContentView(), true); tabHost.addTab(tabHost.newTabSpec("tab1") .setIndicator("tab1") .setContent(R.id.view1)); tabHost.addTab(tabHost.newTabSpec("tab2") .setIndicator("tab2") .setContent(R.id.view2)); tabHost.addTab(tabHost.newTabSpec("tab3") .setIndicator("tab3") .setContent(R.id.view3));

• Loading Youtube Iframe API with RequireJS

  - by davidgnin

  I'm trying to use the Youtube Iframe API inside a module definded with Require JS. As this API is loaded async and calls a function once is loaded, I used a requireJS plugin called "async", that worked before with google maps api. However, this time something isn't working. My module starts this way: define(['text!fmwk/widgets/video/video.html','fmwk/utils/browser','async!http://www.youtube.com/iframe_api'], function (videoTpl,root) { ... }); and chrome console fires this error: Uncaught Error: Load timeout for modules: async!http://www.youtube.com/iframe_api_unnormalized3,async!http://www.youtube.com/iframe_api http://requirejs.org/docs/errors.html#timeout If I don't use async plugin the object YT or its functions are undefinded, and the same happens if I download the API code. The API is loaded sometimes if I put an script tag in the head tag of the html file. All this is expected, but I don't understand because async plugin fails. Thank you for your attention and help :)

• Multiple key/value pairs in HTTP POST where key is the same name

  - by randombits

  I'm working on an API that accepts data from remote clients, some of which where the key in an HTTP POST almost functions as an array. In english what this means is say I have a resource on my server called "class". A class in this sense, is the type a student sits in and a teacher educates in. When the user submits an HTTP POST to create a new class for their application, a lot of the key value pairs look like: student_name: Bob Smith student_name: Jane Smith student_name: Chris Smith What's the best way to handle this on both the client side (let's say the client is cURL or ActiveResource, whatever..) and what's a decent way of handling this on the server-side if my server is a Ruby on Rails app? Need a way to allow for multiple keys with the same name and without any namespace clashing or loss of data.

• sql server 2005 reporting services-- how to use multiple datasets in report

  - by larryq

  Hi everyone, I'm new to SQL Server reporting services, and am trying to decipher an existing report. It's nothing too bad, but I notice it does have two report datasets defined. (They are generated via separate stored procedures) I'm trying to figure out where and how the report datasets are linked together so the Fields collection has both sets of columns available and the report has a single rowset to traverse. Is there a section in the report layout where a joining of datasets is defined? I'm using Visual Studio 2005 to design and preview the report fwiw. Thanks for your help!

• WebSphere MQ/MQSeries - Possible to send a message to multiple queues with single call?

  - by Jeffrey White

  I'm queuing messages to a WebSphere MQ queue (NB: A point-to-point queue -- not a topic) using a stored procedure in my Oracle database. Is there a way to publish each message to multiple queues with a single call? What I would like is to find a solution that would incur zero additional latency on my database compared to sending the message to a single queue. Solutions that involve changing my WebSphere MQ settings are certainly welcome! What I had in mind was somehow creating a "clone" queue that got all the same messages as the original one, but I've been unable to locate anything like this in the documentation. Thanks, Jeff

• Jquery Widget Performance

  - by jamie-wilson

  I am working on an interface which involves ALOT of javascript. There is a calendar and blocks drawn on the calendar. The calendar is a jQuery widget, which works beautifully. The blocks drawn on top are also jQuery widgets. While it works - I am wondering, every time I create another block, is the widget fully duplicating, or is it referencing the widget? If I end up with 200 blocks on the screen, do I have 200 copies of the widget? Because if so i'm sure this will impact the performance quite heavily. Also it would determine whether I have functions inside the widget, or have them external to the widget looking in if that makes sense. Just putting some feelers out there for thoughts. I couldn't find anything by searching online.

• Mysql: Convert DB from local time to UTC

  - by Joernsn

  I need to convert an existing (datetime fields) db from local time ut UTC. The values are stored ad datetimes on a server with time zone CET (+1) (with summertime +2). When selecting data I use UNIX_TIMESTAMP(), which magically compensates for everything, ie, time zone shift and dst (if i've read the docs right). I'm moving the db to a new server with UTC as system time. Simply subtracting -1 H won't work, as summer time is +2. Any ideas for a clever way to do this? (using sql or some script lang)

• The cost of nested methods

  - by Palimondo

  In Scala one might define methods inside other methods. This limits their scope of use to inside of definition block. I use them to improve readability of code that uses several higher-order functions. In contrast to anonymous function literals, this allows me to give them meaningful names before passing them on. For example: class AggregatedPerson extends HashSet[PersonRecord] { def mostFrequentName: String = { type NameCount = (String, Int) def moreFirst(a: NameCount, b: NameCount) = a._2 > b._2 def countOccurrences(nameGroup: (String, List[PersonRecord])) = (nameGroup._1, nameGroup._2.size) iterator.toList.groupBy(_.fullName). map(countOccurrences).iterator.toList. sortWith(moreFirst).head._1 } } Is there any runtime cost because of the nested method definition I should be aware of? Does the answer differ for closures?

• Importing large datasets on iPhone using CoreData

  - by Matthes

  Hi there, I'm facing very annoying problem. My iPhone app is loading it's data from a network server. Data are sent as plist and when parsed, it neeeds to be stored to SQLite db using CoreData. Issue is that in some cases those datasets are too big (5000+ records) and import takes way too long. More on that, when iPhone tries to suspend the screen, Watchdog kills the app because it's still processing the import and does not respond up to 5 seconds, so import is never finished. I used all recommended techniques according to article "Efficiently Importing Data" http://developer.apple.com/mac/library/DOCUMENTATION/Cocoa/Conceptual/CoreData/Articles/cdImporting.html and other docs concerning this, but it's still awfully slow. Solution I'm looking for is to let app suspend, but let import run in behind (better one) or to prevent attempts to suspend the app at all. Or any better idea is welcomed too. Any tips on how to overcome these issues are highly appreciated! Thanks

• How to add Transactions with a DataSet created using the Add Connection Wizard?

  - by RoguePlanetoid

  I have a DataSet that I have added to my project where I can Insert and Add records using the Add Query function in Visual Studio 2010, however I want to add transactions to this, I have found a few examples but cannot seem to find one that works with these. I know I need to use the SQLClient.SQLTransaction Class somehow. I used the Add New Data Source Wizard and added the Tables/View/Functions I need, I just need an example using this process such as How to get the DataConnection my DataSet has used. Assuming all options have been set in the wizard and I am only using the pre-defined adapters and options asked for in this wizard, how to I add the Transaction logic to my Database. For example I have a DataSet called ProductDataSet with the XSD created for this, I have then added my Stock table as a Datasource and Added an AddStock method with a wizard, this also if a new item calls an AddItem method, if either of these fails I want to rollback the AddItem and AddStock in this case.

• Why dont Android applications provide an "Exit" option?

  - by Howiecamp

  Is there something in the Android developer guidelines that disuadea developers from providing the option to "exit" (stop running) an application from within the application itself? I love multitasking and all but it's not clear to me why: the vast majority of apps don't have their own Exit functions and hence just keep running forever don't give you a choice about running when you turn on the phone - they just do by default Both of these things lead to memory usage constantly increasing and your device running with this performance burden all of the time despite the fact that you may only want certain apps to run some of the time. Am I missing something?

  Hi My ASP.Net app is periodically getting the error 'Cannot find the object dbo."XXXX" because it does not exist or you do not have permissions' when it tries to execute a specific stored procedure that writes to the database. I have seen a few forum posts about this issue but the strange thing is that the method works fine almost all of the time, just every now and then I see it in my error logs. Can anyone tell me why this might works Ok most of the time but occassionally fire the error? Application is C# using Enterprise Library 4.1 Data Access. Database is SQL Server 2005 Cheers

• Permanent remove of logo in Windows Scripting Host (WSH() scripts.

  - by antonio

  I know two ways to remove the logo permanently. The "official" one: cscript //Nologo //S Will save current command line options for current user. A ftype approach with admin privileges: ftype wsffile="%SystemRoot%\System32\CScript.exe" //nologo "%%1" %%* ftype jsfile="%SystemRoot%\System32\CScript.exe" //nologo "%%1" %%* ftype vbsfile="%SystemRoot%\System32\CScript.exe" //nologo "%%1" %%* Double-%'s are needed only if you use the lines in a batch file. The latter will all users via affect the reg key HKEY_CLASSES_ROOT\<file>\Shell\Open\Command, where <file> can be wsffile, jsfile or vbsfile. Do you know where are stored the cscript //Nologo //S settings?

• How to run Javascript code before document is completely loaded (using jQuery)

  - by eliza sahoo

  Hi all, I am sahring atip with you all.Please add on to this discussion. JQuery helps faster page load than javascript. JQuery functions are fired when the related elements are loaded, instead of complete pageload. This is a common practice to call a javascript function when page is loaded like window.onload = function(){ alert("Mindfire") } or Inside of which is the code that we want to run right when the page is loaded. Problematically, however, the Javascript code isn't run until all images are finished downloading (this includes banner ads). The reason for using window.onload in the first place is due to the fact that the HTML 'document' isn't finished loading yet, when you first try to run your code. To circumvent both problems, jQuery has a simple statement that checks the document and waits until it's ready to be manipulated, known as the ready event $(document).ready(function() { // Your code here });

• Auto deployment of PHP applications

  - by Christopher McCann

  My team currently has a development web/database server and a live deployment web server and a live database server. We use SVN with the repository stored on the development server but the problem is our deployment process. Currently when we need to deploy an update to the live application we simply use SFTP to transfer from the repository to the live web server and then amend the database on the live server to reflect the development database. This is a really slow process as we also minify all javascript and CSS files. I have used Capistrano for Ruby and Cruise Control for java but I have never used anything for PHP. I'd rather not have to build our own if something already existed. Does anyone know of anything?

• Getting data from function loaded after current function

  I have 2 functions, 1 loaded before another. Some value are determine by the other function data, but since one of it has to load before the other 1, how should I get the data that is loaded after current function? private function wMessage():void { Message.width=Name.width+20; } private function wName():void { Name.x=(Message.x+Message.textWidth)-Name.textWidth; Name.y=Message.y+Message.height; } I've taken out some other unnecessary codes, but as you can see Name position is set according by the position + width of Message, but I want Message's width to be not smaller than Name

Now by looking at the source, I know that the code is under the pagelet_tab_content, but not all of it. I have copied that part and pasted it into my own fan page. The layout looks identical but the functions does not work. Obviously something is missing. For instance, I cant find the in the source which is strange, as I know for definate that it is being used. I have been working with this all day without any result. Maybe there is someone more intelligent and experienced that could help me out?

• What needs checking in for a Grails app?

  - by Bill James

  What parts of a Grails application need to be stored in source-control? Some obvious parts that are needed: grails-app directory test directory web-app directory Now we reach questions like: If we use a Grails plug-in (like gldapo), do we need to check in that plugin? Do Grails plugins install in the Grails directory, or your project? I'm not looking to start a religious war about .project, so please ignore that, but are there any "hidden" project files I need to worry about, along with the plugin issues? Converted to a community wiki, as new versions of Grails have changed some of these solutions, especially as regards plugins.

• PostgreSQL - CREATE INDEX

  - by mocopera

  Hi! I'm working with PostgreSQL to create some data types written in C. For example, I have: typedef struct Point3D { char id[50]; double x; double y; double z; } Point3D; The input and output functions are working properly. But the problem is the following: Every id of Point3D must be unique (and can be NULL), so I have decided to create an unique index on this field id, but is that possible? I'm thinking in something like this: create unique index test_point3d_idx on test_point3d (( getID(columname) )); where getID returns the field ID of columname. But I need to implement getID and I am really blocked. Any advice?

• Assignments failing

  - by Andrei Krotkov

  I'm debugging part of a large project in Visual Studio 2005, and stepping through the code line by line. int speed = this->values.speed; int ref = this->values.ref_speed; After stepping past the first line, values.speed has a value of 61, but for some reason, speed is getting assigned the value 58. After the second line, values.ref_speed has a value of 58, but ref gets assigned the value 30. When paused, you can see that the original values are in fact 61 and 58 respectively, but the values getting stored are different. What is causing this behaviour?

• Iterating Oracle collections of objects with out exploding them

  - by Scott Bailey

  I'm using Oracle object data types to represent a timespan or period. And I've got to do a bunch of operations that involve working with collections of periods. Iterating over collections in SQL is significantly faster than in PL/SQL. CREATE TYPE PERIOD AS OBJECT ( beginning DATE, ending DATE, ... some member functions...); CREATE TYPE PERIOD_TABLE AS TABLE OF PERIOD; -- sample usage SELECT <<period object>>.contains(period2) FROM TABLE(period_table1) t The problem is that the TABLE() function explodes the objects into scalar values, and I really need the objects instead. I could use the scalar values to recreate the objects but this would incur the overhead of re-instantiating the objects. And the period is designed to be subclassed so there would be additional difficulty trying to figure out what to initialize it as. Is there another way to do this that doesn't destroy my objects?

• JavaScript data formatting/pretty printer

  - by Dan

  I'm trying to find a way to 'pretty print' a JavaScript data structure in a human-readable form for debugging. I have a rather big and complicated data structure being stored in JS and I need to write some code to manipulate it. In order to work out what I'm doing and where I'm going wrong, what I really need is to be able to see the data structure in its entirety, and update it whenever I make changes through the UI. All of this stuff I can handle myself, apart from finding a nice way to dump a JavaScript data structure to a human-readable string. JSON would do, but it really needs to be nicely formatted and indented. I'd usually use Firebug's excellent DOM dumping stuff for this, but I really need to be able to see the entire structure at once, which doesn't seem to be possible in Firebug. Any suggestions welcome, thanks in advance.
