I'm currently programming a Discord RPC client, which shows a preview of the Presence.
I found out, that with "https://discordapp.com/api/oauth2/applications/[appid]/assets" you get the asset id from the application and with it the image using "https://cdn.discordapp.com/app-assets/[appid]/[assetid].png". But how do i get the application name with the client id?
I have this class, which sets AppName in customStatus class
class getAppName
{
static DiscordRpcClient client;
public getAppName(string AppId)
{
client = new DiscordRpcClient(AppId);
client.Initialize();
client.OnReady += OnClientReady;
client.OnPresenceUpdate += Client_OnPresenceUpdate;
}
private void Client_OnPresenceUpdate(object sender, PresenceMessage args)
{
customStatus.AppName = (args.Name);
client.ClearPresence();
client.Dispose();
}
private void OnClientReady(object sender, ReadyMessage args)
{
client.SetPresence(new RichPresence { });
}
}
And in customStatus class:
public static string AppName { get; set; }
And:
new getAppName("AppId");
var oldName = AppName;
//this is to wait until the new appname is set
while (oldName == AppName) {}
string newAppname = AppName;
Hope it works for you!

Can anyone please tell me if there is any way in apache spark to store a JavaRDD on mysql database? I am taking input from 2 csv files and then after doing join operations on their contents I need to save the output(the output JavaRDD) in the mysql database. I am already able to save the output successfully on hdfs but I am not finding any information related to apache Spark-MYSQL connection. Below I am posting the code for spark sql. This might serve as a reference to those who are looking for an example for spark-sql.

Here at the end I am saving the result successfully in HDFS. But now I want to save into MYSQL database. Kindly help me out. Thanks
There are two approaches you can use for writing your results back to the database. One is to use something like DBOutputFormat and configure that, and the other is to use foreachPartition on the RDD you want to save and pass in a function which creates a connection to MySQL and writes the result back.
Here is an example using DBOutputFormat.
Create a class that represents your table row -
public class TableRow implements DBWritable
{
public String column1;
public String column2;
#Override
public void write(PreparedStatement statement) throws SQLException
{
statement.setString(1, column1);
statement.setString(2, column2);
}
#Override
public void readFields(ResultSet resultSet) throws SQLException
{
throw new RuntimeException("readFields not implemented");
}
}
Then configure your job and write a mapToPair function. The value doesn't appear to be used. If anyone knows, please post a comment.
String tableName = "YourTableName";
String[] fields = new String[] { "column1", "column2" };
JobConf job = new JobConf();
DBConfiguration.configureDB(job, "com.mysql.jdbc.Driver", "jdbc:mysql://localhost/DatabaseNameHere", "username", "password");
DBOutputFormat.setOutput(job, tableName, fields);
// map your rdd into a table row
JavaPairRDD<TableRow, Object> rows = rdd.mapToPair(...);
rows.saveAsHadoopDataset(job);

I have an idea what this may be but you can stop reading this now (and I apologize for wasting your time in advance) if the answer to the following is no:
Is one (or more) of Request, Response, or MyDemoService in the same namespace as IServiceProtoType?
I suspect that Windsor is getting confused about those, since you are doing...
Types
.FromAssemblyContaining<IServiceProtoType>()
.InSameNamespaceAs<IServiceProtoType>()
... and then configuring everything which that returns as a WCF client proxy. This means that it will be trying to create proxies for things that should not be and hence a Sequence Contains no Elements exception (not the most useful message IMHO but crushing on).
The simple fix would be just to put your IServiceProtoType into its own namespace (I often have a namespace like XXXX.Services for my service contracts).
If that is not acceptable to you then you need to work out another way to identify just the service contracts - take a look at the If method for example or just a good ol' Component.For perhaps.
How to force WCF Rest client to use Json deserializer regardless of content-type?
I am invoking a REST based web service through WCF.
The service returns JSON body, but has content-type "Application/xml". The WCF framework is now giving me the XmlException.
public class MessageFormatter : IClientMessageFormatter
{
private readonly IClientMessageFormatter _formatter;
public MessageFormatter(IClientMessageFormatter formatter)
{
_formatter = formatter;
}
public object DeserializeReply(System.ServiceModel.Channels.Message message, object[] parameters)
{
return _formatter.DeserializeReply(message, parameters);
}
}
that _formatter.DeserializeReply is throwing XmlException. I can't find any example anywhere to force json deserialization on reply.
Edit - The "message" object when moused over is throwing "{... Error reading body: System.Xml.XmlException: The data at the root level is invalid. Line 1, position 1. ...}"
That same object in another one of my project that communicate with a different REST service (Picasa web services) has a what seems like a xml serialised version of JSON object?? So the problem seems further up the stream. I need to find where this object is originating from. I'll go play around with MessageEncoder class.
Edit - (Adding more info)
public class MyBinding : WebHttpBinding
{
public MyBinding(WebHttpSecurityMode mode)
: base(mode)
{
}
public override BindingElementCollection CreateBindingElements()
{
var result = base.CreateBindingElements();
var replacements = result.OfType<MessageEncodingBindingElement>().ToList();
foreach (var messageEncodingBindingElement in replacements)
{
var index = result.IndexOf(messageEncodingBindingElement);
result.Remove(messageEncodingBindingElement);
result.Insert(index, new MyMessageEncodingBindingElement(messageEncodingBindingElement));
}
return result;
}
}
public class MyMessageEncodingBindingElement : MessageEncodingBindingElement
{
private readonly MessageEncodingBindingElement _element;
public MyMessageEncodingBindingElement(MessageEncodingBindingElement element)
{
_element = element;
}
public override BindingElement Clone()
{
var result = _element.Clone();
if (result is MessageEncodingBindingElement)
return new MyMessageEncodingBindingElement(result as MessageEncodingBindingElement);
return result;
}
public override MessageEncoderFactory CreateMessageEncoderFactory()
{
return new MyMessageEncoderFactory(_element.CreateMessageEncoderFactory());
}
}
The method CreateMessageEncoderFactory() is never called even when the constructor and Clone method are hit when breakpoints are set. Any help? I'm trying to set a custom MessageEncoder and MessageEncoderFactory class to modify the instantiation process of the Message object.
You can use a WebContentTypeMapper for that. That's a property of the WebHttpBinding, and you can customize how the deserialization will be done by the encoder from that binding, including forcing it to always use the JSON deserializer, regardless of the incoming message's Content-Type. The code below shows how this can be done.
public class StackOverflow_13225272

[DataContract]
public class Person
{

public string Name { get; set; }

return string.Format("Person[Name={0},Age={1}]", Name, Age);
}
}
[ServiceContract]
public interface ITest
{
[WebGet(ResponseFormat = WebMessageFormat.Json)]
Person GetPerson(string responseContentType);
}
public class Service : ITest
{
public Person GetPerson(string responseContentType)
{
WebOperationContext.Current.OutgoingResponse.ContentType = responseContentType;
return new Person { Name = "John Doe", Age = 29 };
}
}
class AllJsonContentTypeMapper : WebContentTypeMapper
{
public override WebContentFormat GetMessageFormatForContentType(string contentType)
{
return WebContentFormat.Json;
}
}
public static void Test()
{
string baseAddress = "http://" + Environment.MachineName + ":8000/Service";
WebServiceHost host = new WebServiceHost(typeof(Service), new Uri(baseAddress));
host.Open();
Console.WriteLine("Host opened");
#if USE_NETFX4
// This works on .NET 4.0 and beyond
WebHttpBinding binding = new WebHttpBinding();
binding.ContentTypeMapper = new AllJsonContentTypeMapper();
#else
// This works on .NET 3.5
CustomBinding binding = new CustomBinding(new WebHttpBinding());
binding.Elements.Find<WebMessageEncodingBindingElement>().ContentTypeMapper = new AllJsonContentTypeMapper();
ChannelFactory<ITest> factory = new ChannelFactory<ITest>(binding, new EndpointAddress(baseAddress));
#endif
ChannelFactory<ITest> factory = new ChannelFactory<ITest>(binding, new EndpointAddress(baseAddress));
factory.Endpoint.Behaviors.Add(new WebHttpBehavior());
ITest proxy = factory.CreateChannel();
Console.WriteLine("With JSON: {0}", proxy.GetPerson("application/json"));
Console.WriteLine("With XML: {0}", proxy.GetPerson("application/xml"));
Console.Write("Press ENTER to close the host");
Console.ReadLine();
host.Close();
}
}
This might work.

}
I haven't tried it, but I think this will work. You can create a custom IClientMessageFormatter which overwrites the message format to Json, wrap that in a behavior, and then apply that behavior to your client endpoint configuration.
public class ForceJsonClientMessageFormatterDecorator : IClientMessageFormatter
{
private readonly IClientMessageFormatter _decoratedFormatter;
public ForceJsonClientMessageFormatterDecorator(IClientMessageFormatter decoratedFormatter)
{
_decoratedFormatter = decoratedFormatter;
}
public object DeserializeReply(Message message, object[] parameters)
{
message.Properties[WebBodyFormatMessageProperty.Name] = new WebBodyFormatMessageProperty(WebContentFormat.Json);
return _decoratedFormatter.DeserializeReply(message, parameters);
}
public Message SerializeRequest(MessageVersion messageVersion, object[] parameters)
{
return _decoratedFormatter.SerializeRequest(messageVersion, parameters);
}
}
public class ForceJsonWebHttpBehavior : WebHttpBehavior
{
protected override IClientMessageFormatter GetReplyClientFormatter(OperationDescription operationDescription, ServiceEndpoint endpoint)
{
IClientMessageFormatter decoratedFormatter = base.GetReplyClientFormatter(operationDescription, endpoint);
return new ForceJsonClientMessageFormatterDecorator(decoratedFormatter);
}
}
Hi I start learn Fluent NHibernate. I am using this tutorial http://www.d80.co.uk/post/2011/02/20/Linq-to-NHibernate-Tutorial.aspx.

public virtual string Nick { get; set; }
public virtual string Password { get; set; }
}
public class AccountMap:ClassMap<Account>
{
public AccountMap()
{
Id(x => x.Id);
Map(x => x.Nick);
Map(x => x.Password);
}
}
public class NHiberanteHelper

{
if (_sessionFactory == null)
InitializeSessionFactory();
return _sessionFactory;
}
}
private static void InitializeSessionFactory()
{
_sessionFactory = Fluently.Configure()
//NHibernate bude pouzivat ovladace pre MS SQL 2008
.Database(MsSqlConfiguration.MsSql2008

)
//urci NHibernatu kde ma hladat mapovacie subory
.Mappings(m=>m.FluentMappings.AddFromAssemblyOf<Account>())
//ak tabs nie su v DB vytvori
.ExposeConfiguration(cfg => new SchemaExport(cfg).Create(true, true))
//vytvori jeden session pre cely life-time apps
.BuildSessionFactory();
}
public static ISession OpenSession()
{
return SessionFactory.OpenSession();
}
}
class Program
{
static void Main(string[] args)
{
using (var session = NHiberanteHelper.OpenSession())
{
using (var trans = session.BeginTransaction())
{
var account = new Account
{
Nick = "dfdwf",
Password = "xxx"
};
session.Save(account);
trans.Commit();
}
}
Console.ReadKey();
}
}
Problem is that this Fluent configuration always drop table in database.
I need only check if table doesnt exist so create table not always when code run drop table.
Your call to new SchemaExport(cfg).Create(true, true) is exporting the configuration to the database. This will drop and re-create it (it's not clever enough to work out the differences and just execute them.
You could use SchemaUpdate, which will update the schema instead. Here's a blog post about it: http://geekswithblogs.net/dotnetnomad/archive/2010/02/22/138094.aspx
I would always prefer to update tables myself or use something like Redgate's SQLCompare to update a schema whilst preserving data.
