• Why Camera.setParameters(Camera.Parameters) has no effect on Sony-Ericsson X10 and Droid?

  - by mobilekid

  Has anyone come across a strange behaviour with the Camera API when used on Sony-Ericsson X10 or Droid? For example the following code doesn't work on those devices. As a result I'm getting a lot of negative feedback on the Market translating into many cancelled orders... mParameters.set("rotation", orientation); mParameters.set("jpeg-quality", img_quality); mParameters.set("picture-size", "1024x768"); mCamera.setParameters(mParameters); Could you suggest an alternative way of achieving the same? Thanks.

• C++ execution error: This application has requested the Runtime to terminate it in an unusual way.

  - by user1846547

  I am trying to run a C++ program and am getting the following error message when I try to run the program using - Codeblocks IDE and SQL API: "This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information. Process returned 3 (0x3) execution time : 7.547 s Press any key to continue." The program compiles fine but on execution throws this error. My current OS is Windows server 2003 - SP2 (32 bit). Also program compiles and executes fine on Windows XP (32 bit) without any hassles. I checked the services (services.msc) running on my XP machine and compared with Windows server 2003 and found the settings same. Can someone please have a look and help me resolve the issue? thanks, Dhruv

• Retrieve a cross domain RSS(xml) through Javascript

  - by Ajay

  I have seen server side proxy workarounds for retrieving rss (xmls) from cross-domains. In fact this very question addressess my same problem but gives out a different solution. I have a constraint of do not use a proxy to retrieve rss feeds. And hence the Google AJAX Feed API solution also goes out of picture. Is there a client-only workaround for this problem. JSONP is the solution for requests that respond with JSON output. But here, I have RSS feeds which can respond with pure xml . How do I solve the problem.

• Google App Engine, Java, and HTTP Performance

  - by polyclef

  A friend and I are currently working on a turn-based game with chat with both desktop browser and Android clients, with Google App Engine as the server. We're using the Java API for GAE and using HTTP for communication with the server. We've implemented simple chat functionality, and we're getting undesirable latencies 1-3 seconds from both the browser and Android clients while just posting simple one-word chat messages. My friend thought it would be best to use XMPP instead of HTTP, but we want to use a Google Accounts cookie for authentication from the Android client, and according to the GAE documentation, XMPP clients cannot use a Google Accounts cookie and must use the user's password. Does anyone have any suggestions as to where the latency might be coming from, how to troubleshoot it, and/or what to do about it? Also, is anyone aware of any opensource implementations of chat (or something similar) on GAE done in Java? Can't seem to find any.

• Access uploaded file in JSON encoded data

  - by okello

  I've encoded my form data into JSON. This has been achieved by the following ExtJS store configuration: Ext.define('XXX.store.Registration', { extend: 'Ext.data.Store', model: 'XXX.model.Registration', autoLoad: true, pageSize: 15, autoLoad: { start: 0, limit: 15 }, proxy: { type: 'ajax', api: { create: './server/registration/create.php', read: './server/registration/get.php', update: './server/registration/update.php', destroy: './server/registration/destroy.php' }, reader: { type: 'json', root: 'registrations', successProperty: 'success' }, writer: { type: 'json', writeAllFields: true, encode: true, root: 'registrations' } } }); My server side code has been implemented in PHP. I can access the encoded form fields by using the field name as a key, as exemplified below: $reg = $_REQUEST['registrations']; $data = json_decode(stripslashes($reg)); $registerNum = $data->registerNum; $folioNum = $data->folioNum; One of the fields in my form is a fileuploadfield. How can I access the uploaded file from the uploaded JSON. Any assistance will be highly appreciated.

• How can I print a text in two columns using Java Swing?

  - by Jonas

  I have a longer text saved in a String. I would like to print the text in two columns on a single page. How can I do this using Java Swing? I don't understand how I can wrap the text when it's time to use a new line. I have read Lesson: Printing in the Java tutorial, but I haven't found any useful methods for working with text or Strings except FontMetrics. Is there any good methods in the Java API for this or is there any good library I can use for this?

• fstream file I/O question

  - by Konrad

  Hi, I am trying to work out if I need to call close on a fstream object if the intial open failed. i.e. std::fstream strm; strm.open( "filename" ); if( ! strm.fail() ) { // Do something strm.close(); // [1] } strm.close(); // [2] Where should close be called here - should it always be called [2] or only if the open succeeds[1]? I may be going over the top here, but coming from the Windows API way of typically doing this I have CloseHandle( ... ); embedded in my mind :-)

• How do I create a create and execute an SQL command using OleDB directly?

  - by Pagis

  I want to use the OleDB interfaces directly to open a connection to a DB, create a command and executing it (for example using the ICommandText interface). The main thing I can't find is how to create the connection and the command object and how to connect the object that implements the ICommandText to the connection. In ADO I would just use the ActiveConnection property but I want to do this directly on the OleDB interfaces. Also, if anyone can recommend a tutorial to OleDB, ether online or a book, free or not that would be great (but a tutorial and not just a reference / API) I'm using C++ but any native code would be fine.

• Why are configuration arrays acceptible parameters in PHP and Javascript?

  - by RenderIn

  In most other OO languages it would be sacrilege to have each function receive a single associative array of Objects rather than enumerating each in the method signature. Why is it acceptable and commonly used in most popular frameworks for both of these languages to do this? Is there some justification beyond wishing to have concise method signatures? I do see a benefit in this -- that the API could remain unchanged as new, optional parameters are added. But Javascript and PHP already allow for optional parameters in their method signatures. If anything, it seems like Java or another OO language would benefit from this more... and yet I rarely see this pattern there. What gives?

• Preserve trailing whitespace Sybase

  - by AngryWhenHungry

  I have a big chunk of textual data which I split and write multiple rows of a varchar(255) column of a table. Sometimes, the last character happens to be a space. When I read back this row, the trailing space is chopped and I get only 254 characters. This messes up my data when I append the next row to the end of this one. My code sends the full 255 char (incl space) to the DB API. How can I check that the trailing space is actually written to the table? I am not in a position to rewrite/redesign legacy code. Is there any setting - either in the DB, DB interface, read/write calls etc - that I can use to preserve the trailing space?

• Why are Objective-C instance variables declared in an interface?

  - by Chase

  I'm just getting into Objective-C (Java is my primary OO language). Defining an object's instance variables in the interface instead of the class seems strange. I'm used to an interface being a public API definition with nothing besides method signatures (not counting constants here). Is there some reason that state is defined in an interface (even if it is private) and behaviour is defined in a class. It just seems odd that since objects are state+behavior that the definition would be split into two separate places. Is it a design benefit is some way? A pain in the rear issue that you are just forced to deal with in Objective-C? A non-issue, just different? Any background on why it's done this way? Or can you put object state in a class and I just haven't hit that part in my book yet?

• Limiting what a .net plugin can access

  - by David Hogue

  I have a web application that can load plugins through reflection. It currently uses Assembly.LoadFrom() and Activator.CreateInstance() to get this done. Right now plugins are loaded into the same AppDomain and have access to anything in my app and anything my app could access. What I'm looking for is a way to limit what classes and methods the plugin can access for security purposes. I want to have all of my classes and methods throw an exception when called unless they are whitelisted. I'd be whitelisting basically all the functions in an API class and a few data transfer objects. I also don't want the plugin to be able to access the filesystem or the database on it's own. I think I can do that with trust levels in a separate AppDomain though. Does anyone out there have any good ideas or resources? Is this something that could be done with Code Access Security or the new Security-Transparent Code features in .net 4?

• What weird encoding is movistar Venezuela sms on blackberry using?

  - by cjp

  Send an sms using the normal GSM TextMessage API on the BlackBerry, get back garbage. It's not unicode, phone is set to 7-bit send. Byte size is only off by one. Is there some default crypto thing, or some weird encoding they use? This code works most everywhere else in the world; this definitely seems like a movistar problem. The string that comes back is random 7-bit ascii except for a few high order bytes. Needless to say the source input text is totally 7 bit chars, which should work in sms, ISO-8859 and look the same in UTF charsets. Anybody seen this or got sms working in code on movistar VZ blackberries?

• In web project can we write core services layer without knowledge of UI ?

  - by Silent Warrior

  I am working on web project. We are using flex as UI layer. My question is often we are writing core service layer separately from web/UI layer so we can reuse same services for different UI layer/technology. So practically is it possible to reuse same core layer services without any changes/addition in API with different kind of UI technologies/layers. For e.g. same core service layer with UI technology which supports synchronized request response (e.g. jsp etc.) and non synchronize or event driven UI technology (e.g Ajax, Flex, GWT etc.) or with multiple devices like (computers, mobiles, pdas etc.). Personally I feel its very tough to write core service layer without any knowledge of UI. Looking for thoughts from other people.

• Embedded analog of CouchDB, same as sqlite for SQL Server

  - by Mike Chaliy

  I like an idea of document oriented databases like CouchDB. I am looking for simple analog. My requirements is just: persistance storage for schema less data; some simple in-proc quering; good to have transactions and versioning; ruby API; map/reduce is aslo good to have; should work on shared hosting What I do not need is REST/HTTP interfaces (I will use it in-proc). Also I do not need all scalability stuff.

• How to update (append to) an href in jquery?

  - by John Isaacks

  I have a list of links that all go to a google maps api. the links already have the daddr (destination) parameter in them as static. I am using Geo-Location to find the users position and I want to add the saddr (source address) to the links once I get the data. so basically I will need to add something like &saddr=50.1234567,-50.03452 at the tail end of all the links pointing to google maps All the links have a class called directions-link and from this page I have figured out how to change them: $("a.directions-link").attr("href", "http://www.google.com/"); However I only want to append my value to the end of the href without changing what the href already is. How can I do that? Thanks!!

• Offline navigation software for Android - what is out there?

  - by Ted

  Im looking for navigation software for the Android platform and I have a few requirements: Offline maps. The maps should be stored on the device/memory card so no Internet-connection is required There should be some way to interact with the application "through code"; sending route requests, getting current location perhaps, bringing app to foreground/background, etc. An API so it can be controlled from another application. No monthly fees The only one I found so far to match the above is Sygic Navigation. However, I havent yet been able to communication with the app even though they say that it can be done. Still investigating that...

• UnicodeDecodeError from a GET-parameter in webapp2

  - by Aneon

  I'm getting a UnicodeDecodeError when recieving a GET-parameter from webapp2 that contains unicode characters, and then using it to do a NDB query. I get the same error message when manually running a unicode() on the parameter in the handler, so there either seems to be a problem in webapp2's URL routing or I've missed something. Preferably, all GET-parameters should be converted to unicode before getting passed into the handler so I don't need to do manual conversions in all of my handlers. I actually think it's worked before in an earlier version. The full error message read: UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 1: ordinal not in range(128) The GET-parameter contains the following string: göteborg. It looks fine when I raise an Exception on it, but gives me an error when I (or NDB) use unicode() on it. EDIT: In NDB, it fails on the following code: File "C:\Program Files (x86)\Google\google_appengine\google\appengine\api\datastore_types.py", line 1562, in PackString pbvalue.set_stringvalue(unicode(value).encode('utf-8')) Thanks.

• Android Contact Picker

  - by user1066398

  I was wondering: Is it possible to customize the Android Contact Picker so that it can also allow adding a new contact as a menu option in the default contact list? At the moment, if I invoke the contact picker from my activity, it only displays the default contact list. I would also like the user to be able to create a new contact if it did not exist already. I have searched this quite a lot but do not find appropriate API to do this. There is nothing in ContactContract as far as I can see.

• How to Create a Virtual Windows Drive

  - by HyLian

  Hello, I'm trying to create a Windows Virtual Drive ( like c:\ ) to map a remote storage. The main purpose is to do it in a clear way to the user. Therefore the user wouldn't know that he is writing/reading from another site. I was searching for available products, and i find that FUSE is not an option in Windows and WebDAV maps directly the drive, and i would like to build a middle layer between windows and remote storage to implement some kind of services. Another alternatives exists, such as Dokan, that is very expensive, and System.IO.IsolatedStorage Namespace, that doesn't seem to explicity create a new Windows Drive. Probably pismo ( http://www.pismotechnic.com/ ) is the thing that mostly matches my requirements but I would know if there is another alternative, including some Windows ( C++ or .NET ) native API to do that. Thanks for reading :)

• How could a share a Google map mashup with my own datapoints and links back to my site?

  - by rball

  I currently have a map mashup that has locations that I'm populating from my own database. A few users would like to also show that map on their site(s). I'd like to give them the ability to do that, but would like to retain the actual functionality of the map on my own site: like add "stuff" to places on the map through my a web form on my site. I could open the entire API to allow them to create their own form along with the data points, but most of the people wanting to put up the map aren't developers, they are just enthusiasts that have put together a personal page that they want to spice up. I was thinking I could just provide a JavaScript of some kind that they could then take to place on their site, or maybe an IFRAME of some type, or...any ideas? Anyone implemented this? TIA.
