• Access to Oracle Database with sqlapi C++

  - by Meloun

  Hi, I need to write some data in several database. I choose sqlapi.com I have made it for mysql and mssql. Now I have Problem with Oracle database. I have installed server and client on Ubuntu. In browser it works, but sqlapi says: libnnz10.so: cannot open shared object file: No such file or directory DBMS API Library 'libclntsh.so' loading fails This library is a part of DBMS client installation, not SQLAPI++ Make sure DBMS client is installed and this required library is available for dynamic loading Linux/Unix: 1) The directories in the user's LD_LIBRARY_PATH environment variable 2) The list of libraries cached in /etc/ld.so.cache 3) /usr/lib, followed by /lib There are both of these files depp inside /usr/lib. I have tried a lot of ways to say eclipse path to this folder, but nothing works. Thanks for help.

• How does LocationManager work

  - by user2511882

  I have been going through the google docs for the locationManager API and specifically over the method locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 60000, 10, this); In the above line, the manager will check for location updates after each minute and distance of 10 meters. My question is does it actually take both the parameters into consideration? For example if you are driving along how will the method work? Will it start looking for updated locations since you are over the minimum distance between the two updates or will it wait for a minute irrespective? If someone can tell me its behavior, it would be great. Thanks.!!

• Faster s3 bucket duplication

  - by Sean McCleary

  I have been trying to find a better command line tool for duplicating buckets than s3cmd. s3cmd can duplicate buckets without having to download and upload each file. The command I normally run to duplicate buckets using s3cmd is: s3cmd cp -r --acl-public s3://bucket1 s3://bucket2 This works, but it is very slow as copies each file via the API one at a time. If s3cmd could run in parallel mode, I'd be very happy. Are there other options available as a command line tools or code that people use to duplicate buckets that are faster than s3cmd?

• 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...

• How do I use python wx:Config to access the Windows registry?

  - by GreenAsJade

  I've read http://wxpython.org/docs/api/wx.ConfigBase-class.html I've done some basic things like the appended. What I can see is that Config.Create() returns me some sort of configuration object, which has information about python in it. But clearly that's not what I'm looking for: I seem to be missing the magic to say "give me a Config that is the Windows Registry"... Thanks! GaJ import wx from wx import Config app=wx.App(False) config=Config.Create() config.HasGroup("HKEY_CURRENT_USER") False config.GetFirstEntry() (0, u'', -1) config.GetFirstGroup() (1, u'PythonCore', 1) config.GetNextGroup(1) (0, u'', -1) config.GetNumberOfGroups() 1 config.GetPath() u'' config.HasEntry("PythonCore") False config.GetFirstGroup() (1, u'PythonCore', 1)

• C++, WCHAR[] to std::cout and comparision

  - by michal

  Hi, I need to put WCHAR[] to std::cout ... It is a part of PWLAN_CONNECTION_NOTIFICATION_DATA passed from Native Wifi API callback. I tried simply std::cout << var; but it prints out the numeric address of first char. the comparision (var == L"some text") doesn't work either. The debugger returns the expected value, however the comparision returns 0. How can I convert this array to a standard string(std::string)? Thanks in advance

• Doing a POST with cURL but server shows GET

  - by user1798818

  I am trying to do a simple POST. I am using the code below but when I look at the server log it shows it is doing a POST instead of a GET. Any idea why? Code below. THanks, Mark $url = 'http://www.mydomain.com/api.php'; $ch = curl_init(); $data = array('name' => 'Foo', 'file' => '@path\file.jpg'); $headers = array( 'Content-Type: image/jpeg' ); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_TIMEOUT, '3'); curl_setopt($ch, CURLOPT_HEADER ,1); curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); curl_setopt($ch, CURLOPT_POSTFIELDS, $data); $result = curl_exec( $ch );

• A non-blocking server with java.io

  - by Jon

  Everybody knows that java IO is blocking, and java NIO is non-blocking. In IO you will have to use the thread per client pattern, in NIO you can use one thread for all clients. Now my question follows: is it possible to make a non-blocking design using only the Java IO api. (not NIO) I was thinking about a pattern like this (obviously very simplified); List<Socket> li; for (Socket s : li) { InputStream in = s.getInputStream(); byte[] data = in.available(); in.read(data); // processData(data); (decoding packets, encoding outgoing packets } Also note that the client will always be ready for reading data. What are your opinions on this? Will this be suitable for a server that should at least hold a few hundred of clients without major performance issues?

• Creating files on a time (hourly) basis

  - by Yaniv

  Hi there, I experimenting with twitter streaming API, I use Phirehose to connect to twitter and fetch the data but having problems storing it in files for further processing. Basically what I want to do is to create a file named date("YmdH")."."txt" for every hour of connection. Here is how my code looks like right now (not handling the hourly change of files) public function enqueueStatus($status) $data = json_decode($status,true); if(isset($data['text'])/*more conditions here*/) { $fp = fopen("/tmp/$time.txt"); fwirte ($status,$fp); fclose($fp); } Help is as always much appreciated :)

• So I dynamically load a jar at runtime how do I use it?

  - by justinhj

  So question 194698 shows how to load a jar file at runtime and you can load individual named classes and get a Class object. Now my problem is I want to be able to cast those Classes to the types they really are, but I can't because I can't use an import since the whole point is to load it at runtime rather than compile time. It seems like the way to go is to use reflection to discover the functions and field names, but that seems brittle since the API in the jar files could change and the code won't break until it is run. Is there a better way?

• How do I find out which process is locking a file using .NET?

  I've seen several of answers about using Handle or Process Monitor, but I would like to be able to find out in my own code (C#) which process is locking a file. I have a nasty feeling that I'm going to have to spelunk around in the win32 API, but if anyone has already done this and can put me on the right track, I'd really appreciate the help.

• How to determine the best "framerate" (setInterval delay) to use in a JavaScript animation loop?

  - by Ricket

  When writing a JavaScript animation, you of course make a loop using setInterval (or repeated setTimeout). But what is the best delay to use in the setInterval/setTimeout call(s)? In the jQuery API page for the .animate() function, the user "fbogner" says: Just if anyone is interested: Animations are "rendered" using a setInterval with a time out of 13ms. This is quite fast! Chrome's fastest possible interval is about 10ms. All other browsers "sample" at about 20-30ms. Any idea how jQuery determined to use this specific number?

• Can I put google map functions into a closure?

  - by Joe

  I am trying to write some google map functionlity and playing around with javascript closures with an aim to try organise and structure my code better. I have the following code: var gmapFn ={ init : function(){ if (GBrowserIsCompatible()) { this.mapObj = new GMap2($("#map_canvas")); this.mapObj.setCenter(new google.maps.LatLng(51.512880,-0.134334),16); } } } Then I call it later in a jquery doc ready: $(document).ready(function() { gmapFn.init(); }) I have set up the google map keys and but I get an error on the main.js : uncaught exception: [Exception... "Component returned failure code: 0x80004005 (NS_ERROR_FAILURE)" nsresult: "0x80004005 (NS_ERROR_FAILURE)" location: "JS frame :: http://maps.gstatic.com/intl/en_ALL/mapfiles/193c/maps2.api/main.js :: ig :: line 170" data: no] QO() THe error seems to be thrown at the GBrowserIsCompatible() test which I beieve is down to me using this closure, is there a way to keep it in an closure and get init() working?

• Mysterious logging.basicConfig problem (Python)

  - by Max

  I'm writing a Python script to retrieve data from Flickr. For logging purposes, I have the following setup function: def init_log(logfile): format = '%(asctime)s - %(levelname)s - %(message)s' logging.basicConfig(filename=logfile,level=logging.DEBUG,format=format) I've tested this using the python shell and it works as expected, creating a file if one doesn't already exist. But calling it from within my program is where it stops working. The function is definitely being called, and the logfile parameter is working properly – logging.basicConfig just isn't creating any file. I'm not even getting any errors or warnings. My use of the Python Flickr API may be the culprit, but I doubt it. Any ideas?

• How Android 2.2 interacting with Flash 10.1 (how to use flash from my app)?

  - by zxcat

  Hi! I'm searched adobe and android developers sites, but can't find any details on this. Is it possible to use Flash as a part of my app? E.g. like a widget/GUI element? Or it's integrated in browser only and can't be simple accessible? I know, Adobe AIR apps are supported as standalone .apk. So it must be some API/SDK (from Google) to connect with Flash player. Is there any details, how to program it (more clear: launch swf from my app and interact with it)? Thank you!

• Should member variables of global objects be made global as well?

  - by David Wong

  I'm developing plugins in Eclipse which mandates the use of singleton pattern for the Plugin class in order to access the runtime plugin. The class holds references to objects such as Configuration and Resources. In Eclipse 3.0 plug-in runtime objects are not globally managed and so are not generically accessible. Rather, each plug-in is free to declare API which exposes the plug-in runtime object (e.g., MyPlugin.getInstance() In order for the other components of my system to access these objects, I have to do the following: MyPlugin.getInstance().getConfig().getValue(MyPlugin.CONFIGKEY_SOMEPARAMETER); , which is overly verbose IMO. Since MyPlugin provides global access, wouldn't it be easier for me to just provide global access to the objects it manages as well? MyConfig.getValue(MyPlugin.CONFIGKEY_SOMEPARAMETER); Any thoughts? (I'm actually asking because I was reading about the whole "Global variable access and singletons are evil" debates)

• Android App: Proximity

  - by Eclipser

  Is there an API for Android that will find other people nearby running the same app? For instance, if you were to perform a "scan" it tries to find other people running the same app nearby. Would it be possible to perform the same task across multiple OS (Android, iPhone, Windows, etc.)? Or would the best way be to just have the app communicate to a server your location and have a server-side app that pushes a list of others nearby??? My goal is to find an easy way to eventually transmit data between two devices contigent on those that are nearby.

• How can I pass in specific parameters to mstest in Visual Studio

  - by Eric Langland

  I'm trying to modify my test projuect to allow for remote invocation of an api we're building. Right now the tests are hard coded to run locally(against localhost), but I would like to be able to point the tests at any endpoint (even remote ones in production). Ideally there would be a place in the .testsettings for config values to be stored. Sadly this isn't the case. Or, being able to pass parameters to MSTest that the test would read...? Any ideas? Thanks in advance.

• XCode iPhone OS Deployment Target Tool

  - by Trah Divad

  Problem I'm currently stuck trying to figure out what "iPhone OS Deployment Target" setting to use. I do not want to write conditional code right now, so I'd like the lowest version that runs my application fine. At first I thought it would be 2.0 as I wasn't using any 3.0 features, but then i realized that AVAudioRecorder is a 3.0 API. I don't want to be manually checking EVERY function I use in the documentation. Question Is there a tool that will check the OS availability of each functions you call in your code to figure out what the Deployment Target should be? That tool could be a good old compiler, but the latest version of the iPhone SDK does not come with the PRE-3.0 SDKs.

• Programatically determining file "size on disk" in advance

  - by porkchop

  I need to know how big a given in-memory buffer will be as an on-disk (usb stick) file before I write it. I know that unless the size falls on the block size boundary, its likely to get rounded up, e.g. a 1 byte file takes up 4096 bytes on-disk. I'm currently doing this using GetDiskFreeSpace() to work out the disk block size, then using this to calculate the on-disk size like this: GetDiskFreeSpace(szDrive, &dwSectorsPerCluster, &dwBytesPerSector, NULL, NULL); dwBlockSize = dwSectorsPerCuster * dwBytesPerSector; if (dwInMemorySize % dwBlockSize != 0) { dwSizeOnDisk = ((dwInMemorySize / dwBlockSize) * dwBlockSize) + dwBlockSize; } else { dwSizeOnDisk = dwInMemorySize; } Which seems to work fine, BUT GetDiskFreeSpace() only works on disks up to 2GB according to MSDN. GetDiskFreeSpaceEx() doesn't return the same information, so my question is, how else can I calculate this information for drives 2GB? Is there an API call I've missed? Can I assume some hard values depending on the overall disk size?

• Create Class objects based on type signature

  - by Andreas_D

  Class.forName(boolean.class.getName()); This doesn't work in Java - the virtual machine slaps you with a ClassNotFoundException. I was in need for something like that because I wanted to reflect methods based on Strings that included the method signatures, like public void doSomething(boolean yesWeCan, java.lang.String[] presidents); At the end I came up with a custom 'ClassFactory' which translates the type Strings to class objects. This factory includes a lot of handlers for primitive and array type values. The handler for array type objects is something like: if (isArrayOfObjects) { return Class.forName("L["+typeName.replace("[]", "")+";"); } My question is - have I missed something in the Java 1.5+ API that might do the trick?

• 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 :)

• Getting content of a Facebook page in Adobe Flex

  - by cuneyt

  Hi guys, I wrote a Flex application that sends a UrlRequest to Facebook and gets the content of page as a string. The application user clicks a button, and the application connects to Facebook. And no I do not mean using Facebook API. It is like a screen scraper. This application worked locally, but when deployed to server it gives a sandbox security error. I have my crossdomain.xml on the root, but I think the problem is not that. Not only Facebook, but I cannot get any web site when the application is deployed on server. What should I do to get the content of a remote web page?

• 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 to optimize indexing of large number of DB records using Zend_Lucene and Zend_Paginator

  - by jdichev

  So I have this cron script that is deployed and ran using Cron on a host and indexes all the records in a database table - the index is later used both for the front end of the site and the backed operations as well. After the operation, the index is about 3-4 MB. The problem is it takes a lot of resources (CPU: 30+ and a good chunk of memory) and slows the machine down. My question is about how to optimize the operation described below: First there is a select query built using the Zend Framework API, this query is then passed to a Paginator factory that returns a paginator which I am using to balance the current number of items being indexed and not iterate over too much items. The script is iterating over the current items in the paginator object using a foreach loop until reaching the end and then it starts from the beginning after getting items for the next page. I am suspecting this overhead is caused by the Zend_Lucene but no idea how this could be improved.
