hi i want to get follower list via tweetsharp but i have a exception this = Unable to cast object of type 'System.Collections.Generic.List1[TweetSharp.TwitterUser]' to type 'TweetSharp.TwitterCursorList1[TweetSharp.TwitterUser]'.
help me please HOW CAN I GET FOLLOWERLIST?
my code like this
string aranan = "anilsarii";
var AramaAyari = new SearchForUserOptions { Q = aranan, Count = 25 };
var users = ts.SearchForUser(AramaAyari); //Get list of users by query
//...
//var asd=ts.FollowList(new FollowListOptions{ OwnerId= 2603023494});
var followers = ts.ListFollowers(new ListFollowersOptions { Cursor = -1 });
while (followers.NextCursor != null)
{
followers = ts.ListFollowers(new ListFollowersOptions { followers.NextCursor });
}
You may just need to change this line;
followers = ts.ListFollowers(new ListFollowersOptions { followers.NextCursor });
to
followers = ts.ListFollowers(new ListFollowersOptions { Cursor = followers.NextCursor });
If that doesn't work, it's likely a problem in TweetSharp itself. TweetSharp has been abandoned by the original authors and is no longer maintained. As a result, there are a number of problems using it with the current Twitter API, due to changes on Twitter's end in the last few years. However there are several forks of TweetSharp that are current.
I tried your code with the one line modified above using TweetMoaSharp (a fork, available on Nuget, or on github here; https://github.com/Yortw/tweetmoasharp) and it worked fine.
Full disclosure: TweetMoaSharp is a fork primarily maintained by me. If you search Nuget for 'TweetSharp' you should find several others.

When Indexing the items, it fails sometimes and it gives,
The remote server returned an error: (504) Gateway Timeout. [The remote server returned an error: (504) Gateway Timeout.]
The Indexing logic is here as below,
var client = EPiServer.Find.Framework.SearchClient.Instance;
List<ItemModel> items = getItems(); // Get more than 1000 items
List<ItemModel> tempItems = new List<ItemModel>();
//Index 50 items at a time
foreach(var item in items)
{
tempItems.Add(item);
if (tempItems.Count == 50)
{
client.Index(tempItems);
tempItems.Clear();
}
}
What causes this to happen ?
Note: The above mentioned ItemModel is a custom model which is not implemented interfaces (such as IContent). And the items is a list of ItemModel objects.
Additional info:
EPiServer.Find.Framework version 13.0.1
EPiServer.CMS.Core version 11.9.2
I always figured the SearchClient to be a bit sketchy when manipulating data in Find, as far as I figured (but I have to check this) the SearchClient obey under the request limitation of Episerver Find and when doing bigger operations in loops it tends to time out.
Instead, use the ContentIndexer, i.e.
// Use this or injected parameter
var loader = ServiceLocator.Current.GetInstance<IContentLoader>();
// Remove all children or not
var cascade = true;
ContentReference entryPoint = ...where you want to start
// Get all indexable languages from Find
Languages languages = SearchClient.Instance.Settings.Languages;
// Remove all current instances of all languages below the selected content node
//languages.ForEach(x => ContentIndexer.Instance.RemoveFromIndex(entryPoint, cascade.Checked, x.FieldSuffix));
foreach (var lang in languages)
{
if (cascade)
{
var descendents = loader.GetDescendents(entryPoint);
foreach (ContentReference descendent in descendents)
{
ContentIndexer.Instance.RemoveFromIndex(descendent, false, lang.FieldSuffix);
}
}
// Try delete the entrypoint
var entryTest = loader.Get<IContent>(entryPoint, new CultureInfo(lang.FieldSuffix));
if (entryTest != null)
{
var delRes = ContentIndexer.Instance.Delete(entryTest);
}
}
This is the most bulletproof way to delete stuff from the index as far as I figured.
I'm trying to create a basic following algorithm using Swift and Firebase. My current implementation is the following:
static func follow(user: FIRUser, userToFollow: FIRUser) {
database.child("users").child(user.uid).observeSingleEventOfType(.Value, withBlock: { (snapshot) in
var dbFollowing: NSMutableArray! = snapshot.value!["Following"] as! NSMutableArray!
dbFollowing?.addObject(userToFollow.uid)
self.database.child("users/"+(user.uid)+"/").updateChildValues(["Following":dbFollowing!])
//add user uid to userToFollows followers array in similar way
}) { (error) in
print("follow - data could not be retrieved - EXCEPTION: " + error.localizedDescription)
}
}
This retrieves the array of from Firebase node Following, adds the uid of userToFollow, and posts the new array to node Following. This has a few problems:
It is not synchronized so if it is called at the same time on two devices one array will overwrite the other and followers will not be saved.
If there are no followers it cannot deal with a nil array, the program will crash (not the main concern, I can probably address with optionals).
I was wondering what the best practice might be to created a synchronized array of uid/tokens for user followers or post likes. I found the following links, but none seem to directly address my problem and seem to carry other problems with it. I figured it would be wise to ask the community with experience instead of Frankensteining a bunch of solutions together.
https://firebase.googleblog.com/2014/05/handling-synchronized-arrays-with-real.html
https://firebase.google.com/docs/database/ios/save-data (the save data as transaction section)
Thanks for your help!
Thanks to Frank, I figured out a solution using runTransactionBlock. Here it is:
static func follow(user: FIRUser, userToFollow: FIRUser) {
self.database.child("users/"+(user.uid)+"/Following").runTransactionBlock({ (currentData: FIRMutableData!) -> FIRTransactionResult in
var value = currentData?.value as? Array<String>
if (value == nil) {
value = [userToFollow.uid]
} else {
if !(value!.contains(userToFollow.uid)) {
value!.append(userToFollow.uid)
}
}
currentData.value = value!
return FIRTransactionResult.successWithValue(currentData)
}) { (error, committed, snapshot) in
if let error = error {
print("follow - update following transaction - EXCEPTION: " + error.localizedDescription)
}
}
}
This adds the uid of userToFollow to the array Following of user. It can handle nil values and will initialize accordingly, as well as will disregard the request if the user is already following the uid of userToFollow. Let me know if you have any questions!

I'm using the ListFriends() method of TweetSharp library to get all friends of my user (My user has 500 friends).
TwitterCursorList<TwitterUser> friendsList = service.ListFriends(new ListFriendsOptions { Cursor=-1,SkipStatus=true});
while (friendsList.NextCursor != null)
{
foreach (var item in friendsList)
{
count++;
}
TwitterCursorList<TwitterUser> friendsList = service.ListFriends(new ListFriendsOptions { Cursor = friendsList.NextCursor, SkipStatus = true });
}
The above code is working well but it gives me only 300 friends because ListFriends() method has rate limit of 15 per 15 mins and when I'm trying to get more friends its rate limits get over.
How to get all friends in one attempt coz my requirement is to show all friends.
friends/ids will give you the id's of your friends (5.000 max/request). After that you can do a users/show to get the details for the userid's. I don't know what TweetSharp methods you need to use, but I think you can find that in the documentation.
You have one mistake in your code. You cant define friendsList again inside your loop. Thus the last line of code should looks like:
friendsList = service.ListFriends(new ListFriendsOptions { Cursor = friendsList.NextCursor, SkipStatus = true });
You can get the child count via
firebase_node.once('value', function(snapshot) { alert('Count: ' + snapshot.numChildren()); });
But I believe this fetches the entire sub-tree of that node from the server. For huge lists, that seems RAM and latency intensive. Is there a way of getting the count (and/or a list of child names) without fetching the whole thing?
The code snippet you gave does indeed load the entire set of data and then counts it client-side, which can be very slow for large amounts of data.
Firebase doesn't currently have a way to count children without loading data, but we do plan to add it.
For now, one solution would be to maintain a counter of the number of children and update it every time you add a new child. You could use a transaction to count items, like in this code tracking upvodes:
var upvotesRef = new Firebase('https://docs-examples.firebaseio.com/android/saving-data/fireblog/posts/-JRHTHaIs-jNPLXOQivY/upvotes');
upvotesRef.transaction(function (current_value) {
return (current_value || 0) + 1;
});
For more info, see https://www.firebase.com/docs/transactions.html
UPDATE:
Firebase recently released Cloud Functions. With Cloud Functions, you don't need to create your own Server. You can simply write JavaScript functions and upload it to Firebase. Firebase will be responsible for triggering functions whenever an event occurs.
If you want to count upvotes for example, you should create a structure similar to this one:
{
"posts" : {
"-JRHTHaIs-jNPLXOQivY" : {
"upvotes_count":5,
"upvotes" : {
"userX" : true,
"userY" : true,
"userZ" : true,
...
}
}
}
}
And then write a javascript function to increase the upvotes_count when there is a new write to the upvotes node.
const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp(functions.config().firebase);
exports.countlikes = functions.database.ref('/posts/$postid/upvotes').onWrite(event => {
return event.data.ref.parent.child('upvotes_count').set(event.data.numChildren());
});
You can read the Documentation to know how to Get Started with Cloud Functions.
Also, another example of counting posts is here:
https://github.com/firebase/functions-samples/blob/master/child-count/functions/index.js
Update January 2018
The firebase docs have changed so instead of event we now have change and context.
The given example throws an error complaining that event.data is undefined. This pattern seems to work better:
exports.countPrescriptions = functions.database.ref(`/prescriptions`).onWrite((change, context) => {
const data = change.after.val();
const count = Object.keys(data).length;
return change.after.ref.child('_count').set(count);
});
```
This is a little late in the game as several others have already answered nicely, but I'll share how I might implement it.
This hinges on the fact that the Firebase REST API offers a shallow=true parameter.
Assume you have a post object and each one can have a number of comments:
{
"posts": {
"$postKey": {
"comments": {
...
}
}
}
}
You obviously don't want to fetch all of the comments, just the number of comments.
Assuming you have the key for a post, you can send a GET request to
https://yourapp.firebaseio.com/posts/[the post key]/comments?shallow=true.
This will return an object of key-value pairs, where each key is the key of a comment and its value is true:
{
"comment1key": true,
"comment2key": true,
...,
"comment9999key": true
}
The size of this response is much smaller than requesting the equivalent data, and now you can calculate the number of keys in the response to find your value (e.g. commentCount = Object.keys(result).length).
This may not completely solve your problem, as you are still calculating the number of keys returned, and you can't necessarily subscribe to the value as it changes, but it does greatly reduce the size of the returned data without requiring any changes to your schema.
Save the count as you go - and use validation to enforce it. I hacked this together - for keeping a count of unique votes and counts which keeps coming up!. But this time I have tested my suggestion! (notwithstanding cut/paste errors!).
The 'trick' here is to use the node priority to as the vote count...
The data is:
vote/$issueBeingVotedOn/user/$uniqueIdOfVoter = thisVotesCount, priority=thisVotesCount
vote/$issueBeingVotedOn/count = 'user/'+$idOfLastVoter, priority=CountofLastVote
,"vote": {
".read" : true
,".write" : true
,"$issue" : {
"user" : {
"$user" : {
".validate" : "!data.exists() &&
newData.val()==data.parent().parent().child('count').getPriority()+1 &&
newData.val()==newData.GetPriority()"
user can only vote once && count must be one higher than current count && data value must be same as priority.
}
}
,"count" : {
".validate" : "data.parent().child(newData.val()).val()==newData.getPriority() &&
newData.getPriority()==data.getPriority()+1 "
}
count (last voter really) - vote must exist and its count equal newcount, && newcount (priority) can only go up by one.
}
}
Test script to add 10 votes by different users (for this example, id's faked, should user auth.uid in production). Count down by (i--) 10 to see validation fail.
<script src='https://cdn.firebase.com/v0/firebase.js'></script>
<script>
window.fb = new Firebase('https:...vote/iss1/');
window.fb.child('count').once('value', function (dss) {
votes = dss.getPriority();
for (var i=1;i<10;i++) vote(dss,i+votes);
} );
function vote(dss,count)
{
var user='user/zz' + count; // replace with auth.id or whatever
window.fb.child(user).setWithPriority(count,count);
window.fb.child('count').setWithPriority(user,count);
}
</script>
The 'risk' here is that a vote is cast, but the count not updated (haking or script failure). This is why the votes have a unique 'priority' - the script should really start by ensuring that there is no vote with priority higher than the current count, if there is it should complete that transaction before doing its own - get your clients to clean up for you :)
The count needs to be initialised with a priority before you start - forge doesn't let you do this, so a stub script is needed (before the validation is active!).
write a cloud function to and update the node count.
// below function to get the given node count.
const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp(functions.config().firebase);
exports.userscount = functions.database.ref('/users/')
.onWrite(event => {
console.log('users number : ', event.data.numChildren());
return event.data.ref.parent.child('count/users').set(event.data.numChildren());
});

|-count
|-userscount :

I am new to SalesForce (3 months).
Thus far I have been able to create an application in C# that I can use to preform Inserts and Updates to the SalesForce database. These transactions are one at a time.
No I have the need to preform large scale transactions. For example updating thousands of records at a time. Doing them one by one would quickly put us over our allotted API calls per 24 hour period.
I want to utilize the available bulk transactions process to cut down on the number of API calls. Thus far I have not had much luck coding this nor have I found any such documentation.
If anyone could either provide some generic examples or steer me to reliable documentation on the subject I would greatly appreciate it.
FYI, the data I need to use to do the updates and inserts comes from an IBM Unidata database sitting on an AIX machine. So direct web services communication is not realy possible. Getting the data from Unidata has been my headache. I have that worked out. Now the bulk api to SalesForce is my new headache.
Thanks in advance.
Jeff
You don't mention which API you're currently using, but using the soap partner or enterprise APIs you can write records to salesforce 200 at a time. (the create/update/upsert calls all take an array of SObjects).
Using the bulk API you can send data in chunks of thousands of rows at a time.
You can find the documentation for both sets of APIs here
The answers already given are a good start; however, are you sure you need to actually write a custom app that uses the bulk API? The salesforce data loader is a pretty robust tool, includes a command line interface, and can use either the "normal" or bulk data API's. Unless you are needing to do fancy logic as part of your insert/updates, or some sort of more real-time / on-demand loading, the data loader is going to be a better option than a custom app.
(this is the SOAP code though, not the Salesforce "Bulk API" ; careful not to confuse the two)
Mighy be below code provide clear insight on how to do bulk insertion.
/// Demonstrates how to create one or more Account records via the API
public void CreateAccountSample()
{
Account account1 = new Account();
Account account2 = new Account();
// Set some fields on the account1 object. Name field is not set
// so this record should fail as it is a required field.
account1.BillingCity = "Wichita";
account1.BillingCountry = "US";
account1.BillingState = "KA";
account1.BillingStreet = "4322 Haystack Boulevard";
account1.BillingPostalCode = "87901";
// Set some fields on the account2 object
account2.Name = "Golden Straw";
account2.BillingCity = "Oakland";
account2.BillingCountry = "US";
account2.BillingState = "CA";
account2.BillingStreet = "666 Raiders Boulevard";
account2.BillingPostalCode = "97502";
// Create an array of SObjects to hold the accounts
sObject[] accounts = new sObject[2];
// Add the accounts to the SObject array
accounts[0] = account1;
accounts[1] = account2;
// Invoke the create() call
try
{
SaveResult[] saveResults = binding.create(accounts);
// Handle the results
for (int i = 0; i < saveResults.Length; i++)
{
// Determine whether create() succeeded or had errors
if (saveResults[i].success)
{
// No errors, so retrieve the Id created for this record
Console.WriteLine("An Account was created with Id: {0}",
saveResults[i].id);
}
else
{
Console.WriteLine("Item {0} had an error updating", i);
// Handle the errors
foreach (Error error in saveResults[i].errors)
{
Console.WriteLine("Error code is: {0}",
error.statusCode.ToString());
Console.WriteLine("Error message: {0}", error.message);
}
}
}
}
catch (SoapException e)
{
Console.WriteLine(e.Code);
Console.WriteLine(e.Message);
}
}
Please find the small code which may help you to insert the data into salesforce objects using c# and WSDL APIs. I stuck to much to write code in c#. I assigned using direct index after spiting you can use your ways.
I split the column using | (pipe sign). You may change this and also <br>, \n, etc. (row and column breaking)
Means you can enter N rows which are in your HTML/text file. I wrote the program to add order by my designers who put the order on other website and fetch the data from e-commerce website and who has no interface for the salesforce to add/view the order records. I created one object for the same. and add following columns in the object.
Your suggestions are welcome.
