Not getting Twitter api statuses - c#

I am trying to use the following twitter API, but am unable to get user statuses. Tell me what is the error?
WebClient connectTwitter = new WebClient();
connectTwitter.DownloadStringCompleted += new
DownloadStringCompletedEventHandler(connectTwitter_DownloadStringCompleted);
connectTwitter.DownloadStringAsync(new
Uri("https://api.twitter.com/1.1/statuses/user_timeline.json?screen_name=BarackObama"));

You need to authenticate in order to access the Twitter API.
You'll probably want to start here: https://dev.twitter.com/docs/auth/tokens-devtwittercom, and you might want to consider using a C# wrapper for the API, like this: https://github.com/danielcrenna/tweetsharp.

How to Update Account in StripeApi using C#?

I am trying to update Account in Stripe Api using Stripe.netlibrary ,using StripeAccountService and storing it in StripeAccountclass which i made by myself to store the result returned by API :
var accountService = new StripeAccountService("secretKey in string");
StripeRequestOptions option = new StripeRequestOptions();
option.StripeConnectAccountId = "AccountId to update";
StripeAccount x = accountService.Get(option);
x.Email = "Local#local.com";
//Then i do not know how to save changes back to api now.
But StripeAccountService class has no Update method define. How I can perform update on the Account.
I am using this library. Stripe api does have an update method too here.
Stripe.net does not support managed accounts: "Managed Accounts are a valuable service as well, but they are not available in Stripe.net yet." https://github.com/jaymedavis/stripe.net#stripe-connect
Stripe.net doesnot support Managed account but it can be done using following approach it is for update account.
I won't be able to give code but can provide the correct approach, it is tested.
https://api.stripe.com/v1/account
is the Url for updating stripe account.
Now you need to add two header and a body you can try WebRequest or httpclient class.
The reason i am unable to provide code because i did not do any research in adding multiple headers and a body.
so it would look something like this
Header
Property value
Authorization bearer "SecretKey"
Stripe-Account "acct_16uR8kKN01245679"
Body
Property value
email "test#test.com"
support_phone "555-867-5309"
You can see complete property list here. i picked few for demonstration purpose only.
Then save the response in any variable and it is done.

OneDrive API with C#, get authentication code programmatic

I have to write an application, no matter what language (c#, Java, shell, python ...) that can connect to OneDrive and then uploads file.
Following the OneDrive API I found that i need in one step to go to the browser (manually and to post a url that combines client_id and client_security to get an authentication code so i can connect my client with it to get the access token. (oAuth2 protocol)
I need to get the access_token pragmatically, i don't need any manual step to be involved.
I tried in c# to use the WebBrowser component to navigate to the url and to get the access token, I found that the browser stays in the same url and not getting the final url that includes the auth_code!
My code looks like:
// Initialize a new Client (without an Access/Refresh tokens
var client = new Client(options);
// Get the OAuth Request Url
var authRequestUrl = client.GetAuthorizationRequestUrl(new[] { Scope.Basic, Scope.Signin, Scope.SkyDrive, Scope.SkyDriveUpdate });
// TODO: Navigate to authRequestUrl using the browser, and retrieve the Authorization Code from the response
WebBrowser wb = new WebBrowser();
wb.AllowNavigation = true;
wb.ScrollBarsEnabled = false;
wb.ScriptErrorsSuppressed = true;
wb.Navigate(authRequestUrl);
Console.WriteLine(wb.Version);
while (wb.ReadyState != WebBrowserReadyState.Complete)
{
Application.DoEvents();
}
wb.Document.InvokeScript("evt_Login_onload(event)");
Uri myUrl = wb.Url;
Anyone can help with fixing this, or maybe suggest other ideas please?
Thanks in Advance!
It looks like you're creating a Windows desktop app using C#. There's actually an example at https://msdn.microsoft.com/en-us/library/hh826529.aspx for using the WebBrowser class to get the authorization code, then the token, then make an API. In short, you'll first need to send a request to the following URL with your client_id and scopes.
https://login.live.com/oauth20_authorize.srf?client_id=YOUR_CLIENT_ID&scope=YOUR_SCOPE_STRING&response_type=code&redirect_uri=https://login.live.com/oauth20_desktop.srf
In the response, you'll get the authorization code which you'll need to use to send another request to with your client_id, client_secret, authorization code like the following.
https://login.live.com/oauth20_token.srf?client_id=YOUR_CLIENT_ID&client_secret=YOUR_CLIENT_SECRET&redirect_uri=https://login.live.com/oauth20_desktop.srf&code=AUTHORIZATION_CODE&grant_type=authorization_code
When you finally receive the access token, you can make requests to the API using your access token similar to the following.
"https://apis.live.net/v5.0/me?access_token=ACCESS_TOKEN". The "me" can be changed to any other folder or directory.
I hope that helps.
dont u think the scope u provided are wrong, they should be wl.basic, wl.signin, and if ur using new onedrive api then it should be onedrive.readonly or onedrive.readwrite
if ur using liveconnect api for the purpose of using onedrive then scope should be wl.skydrive or wl.contacts_skydrive or wl.skydrive_update
depending upon ur uses (refer https://msdn.microsoft.com/en-us/library/hh243646.aspx)
and can u more elaborate how ur trying to get the access_token, from above it is quite confusing to me
Have you solved you issue?
Have you tried to use the LiveSDK to authenticate?
Have a look at my question there, it might help you :
Onedrive API vs LiveSDK
I have used the following code, after installing both the LiveSDK and the OneDrive SDK, and this does not require any login after the first authorization. However it "may" have to be a RT app (windows store or windows phone store)
var authClient = new LiveAuthClient();
var authResult = await authClient.LoginAsync(new string[] {
"wl.signin", "onedrive.readwrite", "onedrive.appfolder"});
if (authResult.Session == null)
throw new InvalidOperationException("You need to sign in and give consent to the app.");
var Connection = new ODConnection("https://api.onedrive.com/v1.0",
new MicrosoftAccountAuthenticationInfo() { TokenType = "Bearer",
AccessToken = odArgs.Session.AccessToken });
Toan-Nguyen's answer almost helps me. On the step 2 (when I should send a request with authorization code) I get the response with error "Public clients can't send client secret". This answer said it's neccessary to remove the attribute client_secret from url.

Get Facebook objects information with C#

I'm new to facebook development. I'm using C# on Windows Form and I'm searching for a way to get information about a post on facebook.
I've read documentation and see that I can use FQL to query facebook object.
My questions:
is using FQL it a good way in WindowsForm solutions ?
I need to get the count on how many 'like' are done on an object (link or photo). Can I do this with like Table ?
I need to know who is sharing my facebook objects (link or photo). Where is the relative Table I can use ?
Thanks for your help.
I haven't had a lot of luck with FQL and prefer to use the graph api
Using this in combination with the facebook SDK dll you can quickly retrieve information about a post as a json object using the following code.
var client = new FacebookClient(accessToken);
var jsonPost = (JsonObject) client.Get(postId);
As for seeing who has shared your objects I'm not sure if that can be done using the graphAPI, you would be able to see likes and comments of a object by using
var client = new FacebookClient(accessToken);
var jsonLikes = (JsonObject) client.Get(postId + "/likes");
var jsonComents = (JsonObject) client.Get(postId + "/comments");

How do I get Google Calendar feed from user's access token?

Using OAuth I do get access token from Google. The sample that comes with Google and even this one:
http://code.google.com/p/google-api-dotnet-client/source/browse/Tasks.SimpleOAuth2/Program.cs?repo=samples
show how to use Tasks API. However, I want to use Calendar API. I want to get access to user's calendar. Can anybody tell me how do I do that?
Take a look at the samples:
Getting Started with the .NET Client Library
On the right side of the page linked above there is a screen shot showing the sample projects contained in the Google Data API solution. They proofed to be very helpful (I used them to start my own Google Calendar application).
I recommend keeping both your own solution and the sample solution open. This way you can switch between the examples and your own implementation.
I also recommend to use the NuGet packages:
Google.GData.AccessControl
Google.GData.Calendar
Google.GData.Client
Google.GData.Extensions
and more ...
This way you easily stay up to date.
Sample to get the users calendars:
public void LoadCalendars()
{
// Prepare service
CalendarService service = new CalendarService("Your app name");
service.setUserCredentials("username", "password");
CalendarQuery query = new CalendarQuery();
query.Uri = new Uri("https://www.google.com/calendar/feeds/default/allcalendars/full");
CalendarFeed calendarFeed = (CalendarFeed)service.Query(query);
Console.WriteLine("Your calendars:\n");
foreach(CalendarEntry entry in calendarFeed.Entries)
{
Console.WriteLine(entry.Title.Text + "\n");
}
}

facebook C# sdk- comparing from id and userid

using feed dialogue i m posting some data to wall using my app..
but when my friend go to view this feed , its shows the app for itself only..
the reason is i am checking the from id parameter in request.params bt since i m using access token to access user info in graph api, it overlaps the previous params and only code with access token is dere in request..
how to resolve it..??
Well, i dont get what you're asking about exactly , but if you post anything to any user's wall, you should get authorized first, and i think you know that already as you mentioning.
So after you get the access token, you can do that to post anything to the user's wall, assuming that you're using Facebook C# SDK as mentioned in the title:
FacebookClient fbClient = new FacebookClient("AccessToken"); //replace your access token with that..
dynamic me = fbClient.Get("/me");
Dictionary data = new Dictionary();
data.Add("message", txtStatusContent.InnerText.Trim());
fbClient.Post("/me/feed", data);
And that's it.
