• Open source alternative to Sharepoint lists

  - by Thomas

  Sharepoint's lists functionality is powerful. Because I don't want all the other functionality of Sharepoint, I have been looking for an alternative (preferrable open source) without much success. Basically I want to have a platform or web application that: allows us to define custom datatypes (for different kinds of customer products) has the possibility to create views or forms to present to the user for reading, creating or updating the information of the items of a given datatype a ui to setup this configuration is not required but would be nice to have In an ideal scenario there is an API to get the data out afterwards for further processing.

• How to fetch, display Amazon Marketplace listings by item?

  - by Matt G.

  Hi all, My question pretty much says it all: I'm looking for a way to display Amazon Marketplace listings based on an item lookup. Example: If I do a call to ItemLookup with an ASIN of 0590353403 (Harry Potter and the Sorcerer's Stone), I'm looking for a result set of perhaps the top ten new or used Marketplace listings, preferably with seller information attached. I apologize if this is clearly documented somewhere, but I have been looking all through the Amazon API docs and on Google to no avail. StackOverflow doesn't seem to have any Related Questions that match what I'm asking, either. Thanks in advance!

• How do I alter the Epitwitter scripts to post to twitter from a web form?

  - by waterfallrain

  Hello, I am trying to update my twitter status with php and outh using the Epitwitter scripts. The following is the textarea of the web form I created to allow me to update twitter. <textarea name="updatestatus" cols="50" rows="4" id="updatestatus"> </textarea> Do I change this line in my confirm.php script from $status = 'Testing API'; To this $status=$_POST["updatestatus"]; I am wanting to know if I at least got that right so I can look at other possible problems with this form not being able to update twitter. As it stands now I am manually editing the status each time and it works that way perfectly but have not yet figured out how to get a webform to do this.

• Architecture for multiple web apps and databases.

  - by Matt

  We used to have only one web app, but now we are breaking it down into multiple ones. Each one will be packaged as separate product (web app) Some have things in common some do not. It was originally coded with php and using Postgresql 8.4 and CodeIgniter as the framework. I am looking for some good suggestions on how I should set up multiple web apps. They all have their own somewhat unique data. Some data in the databases can be common to some apps but not all. All the apps will be on one server and will have some kind of API to manipulate data. I want it to be structured such that one User account can access any product they purchase. (kinda like google accounts) I do not know if its a good idea to have multiple database, or just to have one big one. eventually we will be using S3 for some videos and other images. Your thoughts and suggestions are much appreciated.

• The ** idiom in C++ for object construction

  - by bobobobo

  In a lot of C++ API'S (COM-based ones spring to mind) that make something for you, the pointer to the object that is constructed is usually required as a ** pointer (and the function will construct and init it for you) You usually see signatures like: HRESULT createAnObject( int howbig, Object **objectYouWantMeToInitialize ) ; -- but you seldom see the new object being passed as a return value. Besides people wanting to see error codes, what is the reason for this? Is it better to use the ** pattern rather than a returned pointer for simpler operations such as: wchar_t* getUnicode( const char* src ) ; Or would this better be written as: void getUnicode( const char* src, wchar_t** dst ) ; The most important thing I can think of is to remember to free it, and the ** way, for some reason, tends to remind me that I have to deallocate it as well.

• Making Google Maps overlay draggable

  - by Rene Saarsoo

  I have extended GOverlay so that it draws small rectangular div at a specified location. But how to make it draggable using Maps API V2? First I tried to just listen the mousedown/up/move DOM events of the div itself. While I got this mostly working, I thought that there has to be a simpler way of doing that. I tried listening the "drag" event of the map itself, which didn't work as I expected. I also found GDraggableObject, which seemed like something to use exactly for that, but I didn't understand how to really use it. Any suggestions?

• Creating TCP network errors for unit testing

  - by Robert S. Barnes

  I'd like to create various network errors during testing. I'm using the Berkely sockets API directly in C++ on Linux. I'm running a mock server in another thread from within Boost.Test which listens on localhost. For instance, I'd like to create a timeout during connect. So far I've tried not calling accept in my mock server and setting the backlog to 1, then making multiple connections, but all seem to successfully connect. I would think that if there wasn't room in the backlog queue I would at least get a connection refused error if not a timeout. I'd like to do this all programatically if possible, but I'd consider using something external like IPchains to intentionally drop certain packets to certain ports during testing, but I'd need to automate creating and removing rules so I could do it from within my Boost.Test unit tests. I suppose I could mock the various system calls involved, but I'd rather go through a real TCP stack if possible. Ideas?

• Get a list of events owned by a facebook page

  - by Tom Wright

  Does anyone know how I can get a list of events owned (created) by a Facebook page? I seem to be able to use the "graph api" to generate a list of the events an entity is attending. I also looked at FQL, but it seems to require that the 'where' clause is an indexable field (and, naturally, the id is the only indexable field). For bonus points, we'd be able to do this without any authentication. (Though I'm resigned to the fact that I'm likely going to need at least a permanent access_token.) If anyone know how to do this I'd be eternally grateful.

• Loop not working when I try to traverse a Simple XML Object

  - by Ben Shelock

  I'm trying to loop through the results from the Last.fm API but it's not working. function get_url($url){ $ch = curl_init(); curl_setopt($ch,CURLOPT_URL,$url); curl_setopt($ch,CURLOPT_RETURNTRANSFER,1); curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,5); $content = curl_exec($ch); curl_close($ch); return $content; } $xml = get_url('http://ws.audioscrobbler.com/2.0/?method=album.search&album=kid%20a&api_key=b25b959554ed76058ac220b7b2e0a026'); $doc = new SimpleXMLElement($xml); $albums = $doc->results->albummatches; foreach($albums as $album){ echo $album->album->name; } This just shows the first album. If I change the code within the foreach loop to echo $album->name; it shows nothing at all. What am I doing wrong?

• What should I do to recompile my static library (originally written in VS6) in visual studio 2008?

  - by user370387

  There is a static library A with c++ classes wrapped by a C API in VS6. I developed a static library B in VS6 using callbacks from library A. The library B is used by the program C (commercial software) as a "user defined library" and linked to produce the program D. Questions: 1) When program C uses VS 6 it works, should it work fine with VS 2008? Because it doesn't. 2) When I tried to recompile library B in VS 2008 it gave me a .lib file with only 28KB, and the old one had more than 2MB. Is it ok? What Am I probably doing wrong? Thanks in advance

• Include a Class in another model / class / lib

  - by jaycode

  I need to use function "image_path" in my lib class. I tried this (and couple of other variations): class CustomHelpers::Base include ActionView::Helpers::AssetTagHelper def self.image_url(source) abs_path = image_path(source) unless abs_path =~ /^http/ abs_path = "#{request.protocol}#{request.host_with_port}#{abs_path}" end abs_path end end But it didn't work. Am I doing it right? Another question is, how do I find the right class to include? For example if I look at this module: http://api.rubyonrails.org/classes/ActionView/Helpers/AssetTagHelper.html is there a rule of thumb how to include that module in a model / library / class / anything else ?

• JavaScript, transform object into array

  - by Šime Vidas

  I've got an object: var obj = { "Mike": 24, "Peter": 23, "Simon": 33, "Tom": 12, "Frank": 31 }; I want to create an array that holds the values of the object. The keys (key names) can be disregarded: [24, 23, 33, 12, 31] The order of the values is NOT important! One solution (obviously) would be do have a function that takes the values and puts them into an array: var arr = valuesToArray(obj); I will accept such a function as the answer. However, I would be more pleased if there would be an API function (ECMAScript, jQuery, browser-specific, ...) that could do this. Is there such a thing?

• Is there a simple script to convert C++ enum to string?

  - by Edu Felipe

  Suppose we have some named enums: enum MyEnum { FOO, BAR = 0x50 }; What I googled for is a script (any language) that scans all the headers in my project and generates a header with one function per enum. char* enum_to_string(MyEnum t); And a implementation with something like this: char* enum_to_string(MyEnum t){ switch(t){ case FOO: return "FOO"; case BAR: return "BAR"; default: return "INVALID ENUM"; } } The gotcha is really with typedefed enums, and unnamed C style enums. Does anybody know something for this? EDIT: The solution should not modify my source, except for the generated functions. The enums are in an API, so using the solutions proposed until now is just not an option.

• SimpleXMLElement empty object

  - by Mike

  Hi, I am trying to parse an xml file using XmlReader but although I am getting a return from the xml file for the (commission) node for some reason I am getting an empty SimpleXMLElement Object returned as well. I don't know if its something to do with while loop,switch or something I missed in the parse setup. This is the xml file I am trying to read from, as you can see there is only 1 result returned: <?xml version="1.0" encoding="UTF-8"?> <cj-api> <commissions total-matched="1"> <commission> <action-status> new </action-status> <action-type> lead </action-type> <aid> 10730981 </aid> <commission-id> 1021015513 </commission-id> <country> </country> <event-date> 2010-05-08T08:08:55-0700 </event-date> <locking-date> 2010-06-10 </locking-date> <order-id> 345007 </order-id> <original> true </original> <original-action-id> 787692438 </original-action-id> <posting-date> 2010-05-08T10:01:22-0700 </posting-date> <website-id> 3201921 </website-id> <cid> 2815954 </cid> <advertiser-name> SPS EurosportBET </advertiser-name> <commission-amount> 0 </commission-amount> <order-discount> 0 </order-discount> <sid> 0 </sid> <sale-amount> 0 </sale-amount> </commission> </commissions> </cj-api> This is my parser: <?php // read $response (xml feed) $file = "datafeed.xml"; $xml = new XMLReader; $xml->open($file); // loop to read in data while ($xml->read()) { switch ($xml->name) { // find the parent node for each commission payment case 'commission': // initalise xml parser $dom = new DomDocument(); $dom_node = $xml ->expand(); $element = $dom->appendChild($dom_node); $dom_string = $dom->saveXML($element); $commission = new SimpleXMLElement($dom_string); // read in data $action_status = $commission->{'action-status'}; $action_type = $commission->{'action-type'}; $aid = $commission->{'aid'}; $commission_id = $commission->{'commission-id'}; $country = $commission->{'country'}; $event_date = $commission->{'event-date'}; $locking_date = $commission->{'locking-date'}; $order_id = $commission->{'order-id'}; $original = $commission->{'original'}; $original_action_id = $commission->{'original_action-id'}; $posting_date = $commission->{'posting-date'}; $website_id = $commission->{'website-id'}; $cid = $commission->{'cid'}; $advertiser_name = $commission->{'advertiser-name'}; $commission_amount = $commission->{'commission-amount'}; $order_discount = $commission->{'order-discount'}; $sid = $commission->{'sid'}; $sale_amount = $commission->{'sale-amount'}; print_r($aid); break; } } ?> The result is : SimpleXMLElement Object ( [0] => 10730981 ) SimpleXMLElement Object ( ) Why is it returning the second object: SimpleXMLElement Object ( ) and what do I need to do correct it?

• Any reason why I shouldn't use couchdb for message passing or realtime activity streams?

  - by Up

  While using ampq or xmpp (rabbitmq or ejabbered that could have couchdb as backends) seems like a good fit to deliver real time updates about friend state in a social gaming platform where updates are small but frequent, I can't help but think why wouldn't couchdb be a good platform to deliver such updates? The main advantage I could think of is its ability to filter updates based on friends and availability of changes api, which makes developing such an application and managing it (including replication) quite easy compared to ampq or xmpp where you have to think about how to manage the pubsub nodes and who is subscribed to them at any point in time. However, I can't help but think this is too good to be true, I can't find information on what couchdb's shortcomings are. Somehow, it feels like using MySQL for message passing which is why I am hesitant to using it. Anyone have any experience in using couchdb for such applications? would you recommend another platform to use?

• Check if a class is subclass of another class in Java

  - by craesh

  Hi! I'm playing around with Java's reflection API and trying to handle some fields. Now I'm stuck with identifying the type of my fields. Strings are easy, just do myField.getType().equals(String.class). The same applies for other non-derived classes. But how do I check derived classes? E.g. LinkedList as subclass of List. I can't find any isSubclassOf(...) or extends(...) method. Do I need to walk through all getSuperClass() and find my supeclass by my own? Thanks! craesh

• Address of instruction causing SIGSEGV in external program

  - by karramba

  I want to get address of instruction that causes external program to SIGSEGV. I tried using ptrace for this, but I'm getting EIP from kernel space (probably default signal handler?). How GDB is able to get the correct EIP? Is there a way to make GDB provide this information using some API? edit: I don't have sources of the program, only binary executable. I need automation, so I can't simply use "run", "info registers" in GDB. I want to implement "info registers" in my own mini-debugger :)

• How Android 2.2 interacting with Flash 10.1?

  - 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!

• Disable Drag&Drop of files in Richtextbox in .NET

  - by Jiri

  Hello, I use a .NET richtextbox and I want to have the EnableAutoDragDrop property set to True. This allows user to drag&drop text, rtf and images around etc. However, I need to process files dropped into the richtextbox myself - I do not want them to be embedded as OLE objects when they are dropped. How can I overcome this? Is there any way to delete embedded files from richtextbox? (I've found API DragAcceptFiles which doesn't work for some reason.) Thanks!

• Using Angularjs with server side templates

  - by codecollision

  For SEO purposes the server renders out the full html template for a given URL on initial load. The site uses angularjs which detects the URL route and renders a client template from the JSON API. For example, you navigate to: /blog/post-title Server responds with post-title content. Angular loads, detects route: /blog/:post_slug and begins to load JSON and render client side template from response. Obviously what Angular does is fine when links are followed after the initial load, but on first load it duplicates effort. My question is if there is a clean way to prevent this situation.

• Webhook data for Orders Paid

  - by David Lazar

  A client recently requested some fancy processing based off of the Gateway attribute registered with a Paid order. When I receive, validate and inspect the JSON of the order, I am logging the gateway attribute and finding it is nil at times. When I check the order using the API after the Webhook, the gateway attribute is present and matches the one rendered in the Shop admin. Is there an explanation for why the gateway can at times be nil? This prevents me from taking care of the client's requested processing.

• Can I use meteor for this?

  - by nitelord

  I'm looking for a way to create an app which has a realtime web interface as well as an API which can be called by a node.js client while sharing most of its code. I'd like to be able to manage data, monitor and execute tasks inside of my app via browser, but also have an automation/scheduling program which connects to my web app and tells it to run various tasks and get results of each task. Unfortunately it doesn't look like I can connect to Meteor from the server, so I'm wondering if there's another approach? Is what I described even possible using Meteor? I have done some testing using socket.io and I think I may be able to do it this way, but Meteor seems like it'd be really great for the realtime user interface.
