Access results from FQL statement using Facebook C Sharp SDK - dynamic

I have this FQL statement:
var fb = new FacebookClient(accessToken);
dynamic result = fb.Get("fql",
new { q = "SELECT post_id, actor_id, target_id, message FROM stream WHERE filter_key in (SELECT filter_key FROM stream_filter WHERE uid=me() AND type='newsfeed') AND is_hidden = 0" });
Now I am trying to access each individual column like this:
dynamic a = result.post_id;
However, it's returning null.
Any ideas?

FQL returns the data inside the property "data"... and that property is an array.... so... to get the whole collection you need:
var rows = result.data;
to get the 'post_id' of the first row:
var post_id = result.data[0].post_id;
So... If you want to show the list of 'post_id'... you could:
foreach (var item in result.data)
{
Response.Write(item.post_id);
}
Hope that helps!

Sitecore Lucene search - hit count differs from result count

I have the following method to return search results based on a supplied query
private List<Item> GetResults(QueryBase qBase)
{
using (IndexSearchContext sc = SearchManager.GetIndex("story").CreateSearchContext())
{
var hits = sc.Search(qBase, int.MaxValue);
var h1 = hits.FetchResults(0, 25);
var h2 = h1.Select(r => r.GetObject<Item>());
var h3 = h2.Where(item => item != null);
return h3.ToList();
}
}
The index being searched indexes web and master content. If I pass in a query that I know matches a single published item and break at the line beginning var h2 = then I see the variable hits has 2 items. This I expect because actually the items are both the same item, one from web and one from master.
However, the variable h1 only has a single result. The result from web has been omitted.
This is the case whether I'm debugging in the context of web or master. Can anyone explain?
When fetching the items using FetchResults method, Sitecore groups the items from lucene by the id of the item. First of the items becomes a SearchResult in the resulting SearchResultCollection object, and other items become Subresults for this results.
For example if you have a home item with id {110D559F-DEA5-42EA-9C1C-8A5DF7E70EF9} with one published version and 4 versions in different languages for the home item, what you'll get from lucene is a single result and 4 subresults for this result:
using (IndexSearchContext sc = SearchManager.GetIndex("story").CreateSearchContext())
{
var hits = sc.Search(qBase, int.MaxValue);
var h1 = hits.FetchResults(0, 25);
foreach (SearchResult result in h1)
{
var url = result.Url;
foreach (SearchResult subresult in result.Subresults)
{
var subUrl = subresult.Url; // other versions of this item
}
}
}
The urls for results and subresults in my case would be:
sitecore://web/{110D559F-DEA5-42EA-9C1C-8A5DF7E70EF9}?lang=en&ver=1
sitecore://master/{110D559F-DEA5-42EA-9C1C-8A5DF7E70EF9}?lang=en&ver=1 (subresult)
sitecore://master/{110D559F-DEA5-42EA-9C1C-8A5DF7E70EF9}?lang=ja-JP&ver=1 (subresult)
sitecore://master/{110D559F-DEA5-42EA-9C1C-8A5DF7E70EF9}?lang=de-DE&ver=1 (subresult)
sitecore://master/{110D559F-DEA5-42EA-9C1C-8A5DF7E70EF9}?lang=da&ver=1 (subresult)
so for retrieving the all the items with their versions you can use this code:
private List<Item> GetResults(QueryBase qBase)
{
using (IndexSearchContext sc = SearchManager.GetIndex("story").CreateSearchContext())
{
var hits = sc.Search(qBase, int.MaxValue);
var h1 = hits.FetchResults(0, 25);
var h2 = h1.Select(r => r.GetObject<Item>()).ToList();
// add other versions of item to the resulting list
foreach (IEnumerable<SearchResult> subresults in h1.Select(sr => sr.Subresults))
{
h2.AddRange(subresults.Select(r => r.GetObject<Item>()));
}
var h3 = h2.Where(item => item != null);
return h3.ToList();
}
}
You can not assume with item will be returned as the first one from the lucene and which items will be returned as subresults. If you want to get any specific item you need to pass version number, language and database to the query.

how to update a column in force.com explorer

SELECT Name, ProfileId, Id, Username FROM User this is the select query to retrive data in Force.com explorer
Now I wan't to update a column how can I do this? update key word it self not working here please give the solution for this.
thanks in advance
In Salesforce you not write to update query same as in SQL.
Please use update method to update column of an object.
More information and sample please read following documents.
https://www.salesforce.com/us/developer/docs/api/Content/sforce_api_calls_update.htm
I found Solution it's working fine now, If any one haveing doubts ask me for Create,Update,Get functionalities
private void UpdateProfileId(string Id)
{
SforceService sfs = new SforceService();
var login = sfs.login(ConfigurationManager.AppSettings["username"],ConfigurationManager.AppSettings["password"]);
sfs.Url = login.serverUrl;
sfs.SessionHeaderValue = new SessionHeader();
sfs.SessionHeaderValue.sessionId = login.sessionId;
var userinfo = login.userInfo;
QueryResult qr = null;
sfs.QueryOptionsValue = new salesforce.QueryOptions();
User[] UpdateUser = new User[1];
User objuser = new User();
objuser.Id = Id;
objuser.ProfileId = "00e90000001CcTnAAK";
UpdateUser[0] = objuser;
try
{
SaveResult[] saveResults = sfs.update(UpdateUser);
foreach (SaveResult saveResult in saveResults)
{
if (saveResult.success)
{
Console.WriteLine("Successfully updated Account ID: " +saveResult.id);
}
}
}
}

RavenDB : Use "Search" only if given within one query

I have a situation where my user is presented with a grid, and it, by default, will just get the first 15 results. However they may type in a name and search for an item across all pages.
Alone, either of these works fine, but I am trying to figure out how to make them work as a single query. This is basically what it looks like...
// find a filter if the user is searching
var filters = request.Filters.ToFilters();
// determine the name to search by
var name = filters.Count > 0 ? filters[0] : null;
// we need to be able to catch some query statistics to make sure that the
// grid view is complete and accurate
RavenQueryStatistics statistics;
// try to query the items listing as quickly as we can, getting only the
// page we want out of it
var items = RavenSession
.Query<Models.Items.Item>()
.Statistics(out statistics) // output our query statistics
.Search(n => n.Name, name)
.Skip((request.Page - 1) * request.PageSize)
.Take(request.PageSize)
.ToArray();
// we need to store the total results so that we can keep the grid up to date
var totalResults = statistics.TotalResults;
return Json(new { data = items, total = totalResults }, JsonRequestBehavior.AllowGet);
The problem is that if no name is given, it does not return anything; Which is not the desired result. (Searching by 'null' doesn't work, obviously.)
Do something like this:
var q= RavenSession
.Query<Models.Items.Item>()
.Statistics(out statistics); // output our query statistics
if(string.IsNullOrEmpty(name) == false)
q = q.Search(n => n.Name, name);
var items = q.Skip((request.Page - 1) * request.PageSize)
.Take(request.PageSize)
.ToArray();

Can I specify sorting for results from the Spotify Apps API?

I'm a novice Javascript programmer, so I apologize if this question makes no sense.
When I do a request for all the albums in a library, I get an array for every album. Is it possible to get these arrays sorted by artist name?
You can sort the array of albums yourself. This solution will place albums with no artist name, first.
var sp = getSpotifyApi(1);
var m = sp.require('sp://import/scripts/api/models')
var sortedAlbums = m.library.albums.sort(function(album1, album2) {
var name1 = album1.artist.name || "";
var name2 = album2.artist.name || "";
return name1.toLocaleLowerCase().localeCompare(name2.toLocaleLowerCase());
});

RuntimeBinderException on dynamic Linq with Facebook C# SDK

I am using the Facebook C# SDK in a canvas app.
When running this code...
public IEnumerable<string> GetFansIds(string pageId, IEnumerable<string> userIds)
{
if (userIds.Count() == 0)
return new List<string>();
var fb = new FacebookApp();
string query = String.Format("select uid from page_fan where uid IN ( {0} ) and page_id = {1}",
String.Join(",", userIds),
pageId
);
dynamic result = fb.Fql(query);
return result.Select((Func<dynamic, string>)(x => x.uid)).ToList();
}
I get the following Exception:
RuntimeBinderException: Cannot perform runtime binding on a null reference
The code does the following:
It performs a FQL query to get an JsonArray contaning JsonObject each with a uid Property (containing the uids of the users that are not fan of some fanpage.
The Select just converts all the dynamic objects into a List<string>
The FQL part just works correctly as i can see the results in the debugger.
The problem is with the Select that I can't make it work.
How can I fix the dynamic lambda ??? (Please don't just tell me to use a foreach, which is what I am currently doing right now)
The problem is that extension methods cannot be used on dynamic objects. Cast the result of the query to a JsonArray and then you can use linq expressions on the JsonArray.
var result = (JsonArray)fb.Fql(query);
return result.Select((Func<dynamic, string>)(x => x.uid)).ToList();
