• Delay after pressing a button

  - by KrLx_roller

  After I press a button, Android parse a JSON file and pick the info it needs. Until yesterday, I was using an external library created by a user and it worked perfectly. But now, I don't want to depend on him, so I've searching info about Google's GSON. I've implemented this library with no problem, but now, after pressing the button that opens a new activity there's a delay. This delay is due to the connection and parsing that are done before the activity shows. How can I force the app to wait the Internet connection until de Activity is shown? It's a lil bit uncomfortable because after pressing the button, it seems that the app has frozen, but after all data is loaded, the new activity appears. Thank you in advance!

• Switching to a VPS

  - by Damian

  Well, I know absolutely nothing about the subject, so I really need help. I currently have a website running on google app-engine (Java) and I can't get it to what I want because of app engine's limitations (no full text search mainly). The traffic is low, never reached 15% of the free quota (around 1500 daily pageviews). I also have 3 sites in drupal hosted in a shared hosting service, and this is giving me problems, because the server speed is awful. The sites are VERY low trafic, but load times are bad, and I might need to add more sites for some clients, so this will only get worse. So, i'm planning to move all that to VPS. The question is, can I have 2 http servers running in the same VPS? because I will need Apache-php-drupal server and a java server (tomcat?). I have really no idea on this, so any tip will be very helpful to me. Thanks!

• Adding controls dynamically at design time vb.net

  - by chris

  I have been developing some custom smart tags. I am using a DesignerActionMethodItem which gets me to a fired method in code. When I try to hit the controls.Add the control is added but it seems the designer is unaware of it. It is never serialized and it goes away when the form is refreshed in the designer. Any help would be greatly appreciated. I am sort of stuck and google hasn't helped me. Please don't send me anything about smart tags that has nothing to do with adding controls dynamically at design time, I have already read so many looking for this.

• Programmitically accessing internal storage (not SD card) on Verizon HTC Droid Incredible (Android)

  - by tliebeck

  Hello, I'm trying to find information on how to programmatically access the HTC Droid Incredible's supposed 8GB of internal storage. To determine the external storage (SD Card) location, I'm using android.os.Environment.getExternalStorageDirectory(). I've not been able to find any corollary for internal phone storage. In examining HTC/Google Nexus One, Motorola Droid, and HTC Dream/G1 phones, there (as would be expected) does not appear to be any mount point for such arbitrary internal storage. On these phones the internal storage is divided amongst /data, /system, and /cache partitions. The Incredible's internal storage is certainly not going to be located in /system. /cache is also unlikely given that it is globally non-readable/non-executable. I'd read in reviews that the phone will still be limited to 512MB or so for apps, suggesting that it is not simply a subdirectory of /data. Any suggestions would be greatly appreciated. I do not have access to a Droid Incredible unit myself, of course.

• Help with Event-Based Components

  - by Joel in Gö

  I have started to look at Event-Based Components (EBCs), a programming method currently being explored by Ralf Wesphal in Germany, in particular. This is a really interesting and promising way to architect a software solution, and gets close to the age-old idea of being able to stick software components together like Lego :) A good starting point is the Channel 9 video here, and there is a fair bit of discussion in German at the Google Group on EBCs. I am however looking for more concrete examples - while the ideas look great, I am finding it hard to translate them into real code for anything more than a trivial project. Does anyone know of any good code examples (in C# preferably), or any more good sites where EBCs are discussed?

• Flex 3: Embedding MovieClip Symbol to Image Control programmatically

  - by BlueDude

  I've reviewed all the documentation and Google results surrounding this and I think I have everything setup correctly. My problem is that the symbol is not appearing in my app. I have a MovieClip symbol that I've embedded to my Flex Component. I need to create a new Image control for each item from my dataProvider and assign this embedded symbol as the Image's source. I thought it was simple but apparently not. Here's a stub of the code: [Embed(source="../assets/assetLib.swf", symbol="StarMC")] private var StarClass:Class; protected function rebuildChildren():void { iterator.seek( CursorBookmark.FIRST ); while ( !iterator.afterLast ) { child = new Image(); var asset:MovieClipAsset = new StarClass() as MovieClipAsset; (child as Image).source = asset; } } I know the child is being created because I can draw a shape and and that appears. Am I doing something wrong? Thank you!

• Reading an Excel file in PHP

  - by Dinah

  I'm trying to read an Excel file (Office 2003). There is an Excel file that needs to be uploaded and its contents parsed. Via Google, I can only find answers to these related (and insufficient topics): generating Excel files, reading Excel XML files, reading Excel CSV files, or incomplete abandoned projects. I own Office 2003 so if I need any files from there, they are available. It's installed on my box but isn't and can't be installed on my shared host. Edit: so far all answers point to PHP-ExcelReader and/or this additional article about how to use it.

• Private JQuery instance

  - by Nir Levy

  We are writing a SaaS like solution that requires our customers to SCRIPT SRC some javascript code we are building (think Google Analytics scenario). We would like to use JQuery. However, since our customers might already have conflicting JQuery versions or other conflicting frameworks (prototype.js for one) we cannot tell them to source jquery.js. We were thinking of coping the jquery source as to create a 'private' jquery instance and simple search/replace the JQuery and $ functions with myJQuery and $J Is there any reason for this not to work? has anyone tried something like this? What can we do about plugins?

• Question about tracking user in a map application using cellid

  - by subh

  I am trying to understand the concept of cellid (http://www.opencellid.org/api) As per that, if we send a request http://www.opencellid.org/cell/get?key=myapikey&mnc=1&mcc=2&lac=200&cellid=234 it will respond with the latitude and longitude. I was wondering if this can be used from within a google map application for tracking a user or it needs to be used from within a mobile device? If it can be used from within a web app, what parameters should it use for mcc: mobile country code (decimal) mnc: mobile network code (decimal) lac: locale area code (decimal) cellid: value of the cell id E.g., will it work if we know the cell number of the person(e.g., 281 222 6700)

• .NET Remoting Client's Problem when running on the machine with Multi NICs

  - by cui chun

  I built a .NET Remoting Client which works quite fine on the machine of single NIC, and lots of testing messages received via remoting event. But when additional NIC was added, the Client seemed to be able to connect the remoting Server, but the testing messages cannot arrive anymore. From debugging, the server end did trigger the event but the client didn't get that. Checking from google and find that a similar problem report: http://www.eggheadcafe.com/community/aspnet/2/10061570/reply.aspx I just wonder if any solutions? Thanks in advance!

• REXML Formatting issues

  - by dagda1

  Hi, I am using REXML to edit an xml file but have ran into difficulties with formatting. My original code looked like this: file = File.new( destination) doc = REXML::Document.new file doc.elements.each("configuration/continuity2") do |element| element.attributes["islive"] = "true" element.attributes["pagetitle"] = "#{@client.page_title}" element.attributes["clientname"] = "#{@client.name}" end doc.elements.each("configuration/continuity2/plans") do |element| element.attributes["storebasedir"] = "#{@client.store_dir}" end I first of all had to add the following code as REXML was adding single quotes instead of double quotes. I found the following via google: REXML::Attribute.class_eval( %q^ def to_string %Q[#@expanded_name="#{to_s().gsub(/"/, '&quot;')}"] end ^ ) I also have a problem in that REXML is reformatting the document. are there ways to stop this? Cheers Paul

• PHP - Loop thru recordset and fire event each n rows

  - by Luciano

  I'm looking for the right logic to loop thru a recordset and fire an event each n times. Searching on Google i've found some discussion on similar situations, but it seems that solutions don't fits my needs. Let's say i have a recordset of 22 rows. I want to loop thru each row and launch a function on the 4th, the 8th, the 12th and so on... Using the modulus operator as shown in this answer, if($i % 4 == 0), i get the event fired each 4 rows, but 22 its not a multiple of 4 so the event is fired till the 20th row and then nothing. Maybe i need to make a division counting rows in 'excess'? Since the recordset will be between 50 and 200 rows i think its not necessary run multiple query of 4 rows, am I wrong? Thanks in advance!

• How to preserve whitespace indentation of text enclosed in HTML <pre> tags excluding the current indentation level of the <pre> tag in the document?

  - by Michael Barton

  I'm trying to display my code on a website but I'm having problems preserving the whitespace indentation correctly. For instance given the following snippet: <html> <body> Here is my code: <pre> def some_funtion return 'Hello, World!' end </pre> <body> </html> This is displayed in the browser as: Here is my code: def some_funtion return 'Hello, World!' end When I would like it displayed as: Here is my code: def some_funtion return 'Hello, World!' end The difference is that that current indentation level of the HTML pre tag is being added to the indentation of the code. I'm using nanoc as a static website generator and I'm using google prettify to also add syntax highlighting. Can anyone offer any suggestions?

• Encode/compress sequence of repeating integers

  - by Alex

  Hey there! I have very long integer sequences that look like this (arbitrary length!): 0000000001110002220033333 Now I need some algorithm to convert this string into something compressed like a9b3a3c3a2d5 Which means "a 9 times, then b 3 times, then a 3 times" and so on, where "a" stands for 0, "b" for 1, "c" for 2 and "d" for 3. How would you do that? So far nothing suitable came to my mind, and I had no luck with google because I didn't really know what to search for. What is this kind of encoding / compression called? PS: I am going to do the encoding with PHP, and the decoding in JavaScript.

• How can I show SQL Server LOGS (2005)

  - by Marcin Rybacki

  Hello, I'm trying to track the error thrown by SQL Server 2005. The problem is SQL Server reports it in my native language so it's hard for me to google it. I think that the core issue would be avialable in English in SQL Server LOGS. I'm running SQL Server Management Studio Express, going to "Management" node, and then SQL Server Logs. I can see the list of logs but I cannot enter them, the only available option in context menu is Refresh. Could you help me to show the contents of those logs?

• SVG drawing application with vector export

  - by Bram Jetten

  I want to create a drawing application where I can place text and images on a canvas. Those elements also need to be interactively manipulated. Eventually the resulting canvas has to be exported to a vector based PDF. An excellent contender for this functionality would be SVG. However, this application also needs to be crossbrowser compatible. I've been browsing around for some time now and have seen a couple of solutions available. I found among others RaphaelJS and Google's SVGWeb for working with SVG. Now for converting those SVG files to a PDF I'm not sure if for instance Batik will offer me what I am looking for. Also, how would bitmap images be handled when converting the SVG to PDF?

• Android on Eclipse - Adding jar files to an Eclipse Android Project

  - by Shalini

  I am developing an Android App that uses the Google APIs Client Library for Java version 1.12.0. I have added the jar files to the /libs folder (and not to a new /lib folder). I get the following error: Dx trouble processing "javax/xml/namespace/QName.class": Ill-advised or mistaken usage of a core class (java.* or javax.*) when not building a core library. I am NOT using Maven though, and all the answers by others seem to make use of Maven. Android version - 4.1.2 API level 16 Eclipse - Java EE Juno Any suggestions on how I can solve this?

• Launching desired version of XCode from Finder

  - by Andy J Buchanan

  My google-fu has failed me, and I guess this may be basic OS X/Xcode knowledge but.... When I double click .xcodeproj files, I'm getting the Beta I have installed launching instead of the stable release - which is the one I actually want. I have tried changing the launch program in the finder info window, but it always displays as "Xcode" and doesn't seem to accept that there are different versions - even though it offers them to me in the drop down list. Is there an xcode setting for this? Thanks.

• Filter user input (paragraph) for links + smileys

  - by Alec Smart

  Hello, I am looking at some sort of existing filter which can sanitize the user input to avoid XSS. Probably I can use htmlspecialchars for that. But at the same time I want to be able to parse all links (should match a.com, www.a.com and http://www.a.com and if it is http://www.aaaaaaaaaaaaaaaaaaaaaaaaaa.com then it should display it as aaa..a.com), e-mails and smileys. I am wondering what is the best way to go about it. I am currently using a php function with some regex, but many times the regex simply fails (because of link recognition is incorrect etc.). I want something very similar to the parser used during Google Chat (even a.com works). Thank you for your time.

• Finding an open and closing tag in Regexp

  - by Rixius

  Is there a way to find custom tags in regexp I.e. match {a}sometext{/a} As well as {c=#fff}sometext{/c} So that it finds the entire block of inner content? The problem is the sometext could have another tag as in: {a=http://www.google.com}{b}Hello, world{/b}{/a} The only solutions I can come up with would match from {a... to .../b} when I want {a... to .../a} is there a single regexp solution, or would it be best to match the start, and then use another method to find the end from the back up, and grab it out that way? I'm using PHP 5.2 so I have all the options that entails.

• Quaere - Anyone using it yet? (LINQ to Objects for Java)

  - by Marty Pitt

  Hi there I'm a .NET guy originally, working in Java recently, and finding I'm really missing LINQ to Objects, specifically for performing filtering against collections. A few people here on Stack Overflow have answered the "LINQ for Java?" question with a single word : Quaere However, on the site it clearly states "Pre-Beta", and there's been no commits to their code for over a year, so I'm guessing the project is pretty much dead. Is anyone actually using this, and / or have any experience with it? The second most common answer appears to be "use Google Collections". Is this the most appropriate Java way? Cheers Marty

• Longest keyword chain?

  - by pg-robban

  As I was typing some constants in Java I noticed I had used 4 keywords in a row, which Eclipse highlighted for me: public static final int. I then took a break from my regular coding and asked myself (and google with no relevant results) what the longest chain of keywords I can use and still have valid code. After a while, the best I could come up with was this method definition: public synchronized static final strictfp int a() { ... which is 6 keywords in Java. Is it possible to go 7, or even higher? What about other languages?

• Want to build simple SQL admin interface to change a few values in a table.

  - by Adam McC

  i am currently building a system in MSSQL 2K5. i have a table that holds information about certain insurance schemes such as overheads and other things. these values will change occasionally and currently i administer the database straight through the management Studio. i would like to build a simple interface that will allow my colleagues to change these values by selecting the company in a dropdown and the current values will populate. they can then edit these values and submit them to the database. is this possible in the current Visual Studio supplied with MSSQL server 2K5 or do i need to get another product. i am confident that with the help of stack overflow and google i can build this myself, but i need pointed in the right direction as to which environment would be easiest and best to start building it. Many thanks, adam
