I am playing around with DisqusSharp:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using WWB.DisqusSharp.Model.DisqusService;
using WWB.DisqusSharp.Infrastructure.Hammock;
namespace DisqusSharpTest
{
class Program
{
static void Main(string[] args)
{
Console.Out.WriteLine("foo");
Console.In.ReadLine();
IDisqusService disqus = new HammockDisqusService("myKey");
IEnumerable<string> names = disqus.GetThreadList("myForumId", new StartLimitArgs { Start = 0, Limit = 5 })
.Payload.Select(disqusThread => disqusThread.Title);
foreach (string name in names)
{
Console.WriteLine(name);
}
}
}
}
After I add references to WWB.DisqusSharp.dll, as well as Hammock.dll and Newtonsoft.Json.dll, this appears to work fine. I use Visual Studio's autocorrect feature and it adds using statements for the WWB classes.
However, when I click "start debugging" or "start without debugging", it complains of a build error, saying that the namespace WWB cannot be found. I then re-add the reference, and it works again, until I hit "start debugging" again.
What am I doing wrong?
I'd be WWB, guess I should add disqussharp to the watch list. Anyhow, I'm not sure the problem you are having, but I'd suggest using the nuget package as a test to make sure things get wired up correctly.

I have tried to search for this but every example I find has a problem like them actually having the same namespace as their class or something.
I am simply trying to start using Linq. When I add new item Host is localhost. I have my database in Visualstudio and my project name is different than the DataContext name but I can't get it initialized. I get error:
'LinkedContext' is a namespace but is used like a type'
here is code...
namespace TryAgain
{
class Program
{
static void Main(string[] args)
{
LinkedContext db = new LinkedContext();
}
}
}
LinkedContext doesn't work? In settings of the Database Diagram it says the Entity Namespace is 'LinkedContext' So what am I missing. I thought I saw you could run that one line of code to connect your database that is already in VisualStudio due to adding a new item and then start playing with it? I just want to be able to practice with a database! Do stuff like:
var example = from x in example.Table
orderby x.field
select x;
you need using LinkedContext at the top of your file. the error you’re getting is telling you LinkedContext is a namespace but you’re treating like a type, ie a class. once you define it at the top you can then use the type that you need within that namespace.
added "using LinkedContext" to the top of code then also had to use LinkedDataContext not just LinkedContext:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using LinkedContext;
namespace TryAgain
{
class Program
{
static void Main(string[] args)
{
LinkedDataContext db = new LinkedDataContext();
var example = from x in db.employees
orderby x.employee_id
select x;
foreach (var whatever in example)
{
Console.WriteLine(whatever.name);
}
I am trying to debug an existing application in VS2010, 4.0 framework. I get this compile-time error:
"The name 'b_resources' does not exist in the current context" .
I cannot see anything wrong in the code below:
using System;
using System.Collections.Generic;
using System.Text;
using System.ComponentModel;
using System.Data;
using System.Drawing;
#if TR
using b_resources = Common.Resources.TResources;
#endif
#if EN
using b_resources = Common.Resources.EnResources;
#endif
namespace Common
{
public static class BResources
{
public static string caption { get { return b_resources.ProductName; } }
public static string company_name { get { return b_resources.CompanyName; } }
}
}
TResources and EnResources are resource files (.resx)
Am I missing some references related to .Net ?
The most obvious question is: do you define the TR or EN compilation symbol in your current build? If not, both #IF statements will be false and the using statement won't be included. In other words, if you do not define those symbols, the following code will be compiled:
using System;
using System.Collections.Generic;
using System.Text;
using System.ComponentModel;
using System.Data;
using System.Drawing;
// Note: missing using statements
namespace Common
{
public static class BResources
{
public static string caption { get { return b_resources.ProductName; } }
public static string company_name{ get { return b_resources.CompanyName; } }
}
}
To check or set compilation symbols, go to your project's properties. Then on the Build tab you see as textbox named Conditional compilation symbols. Check if the symbols are defined there. If not, add one of them there.
If you are using Visual Studio, you can in fact immediately see if this is the case. If a symbol is not defined for the current build, the code within the #IF block will be greyed out. If the symbol is defined, it will display jsut like normal code.
You have no default case so if neither TR or EN is defined you get no definition of b_resources. You need to have some else cases in there so it can always compile. For example, if you wanted your EN resource as default:
#if TR
using b_resources = Common.Resources.TResources;
#elif EN
using b_resources = Common.Resources.EnResources;
#else
using b_resources = Common.Resources.EnResources; // or whatever you want as default
#endif
If neither TR or EN are defined the final else will be included.
For your code to compile, you need to define either TR or EN in the Build settings of your Project properties. Currently neither are defined, so b_resources never gets defined.
I am trying to connect to R from c# using the following code. It looks like C# is not reading the R dll files. My R installation directory is this:
C:\Users\R-2-13\R-2.13.0\bin\i386
and I also downloaded and put the R.NET.dll in the same directory. In Visual Studio, I set the reference to R.NET.dll file. When I run the following code, the code goes the the catch section "unable to find the R Installation". Any ideas? Has anybody got this working?
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using RDotNet;
namespace RNet_Calculator
{
public partial class Form1 : Form
{
// set up basics and create RDotNet instance
// if anticipated install of R is not found, ask the user to find it.
public Form1()
{
InitializeComponent();
bool r_located = false;
while (r_located == false)
{
try
{
REngine.SetDllDirectory(#"C:\Users\R-2-13\R-2.13.0\bin\i386");
REngine.CreateInstance("RDotNet");
r_located = true;
}
catch { MessageBox.Show(#"Unable to find R installation's \bin\i386 folder. Press OK to attempt to locate it.");
MessageBox.Show("error");
}
}
}
private void Form1_Load(object sender, EventArgs e)
{
}
}
}
This is http://rdotnet.codeplex.com/ (RDotNet) to develop Winform applications. While I know Shiny and all the other Web-like R-tools quite well, the combination of c# and R still is my preferred end-user combinations. Try simple things like disabling buttons with Shiny...
Too bad rdotnet is quite buggy; in the current version, it crashes on R exeptions, even in try-catched ones.
This said: please make absolutely sure that you use version 1.5, not the stupidly called "stable" (=early beta) version on the page. Best download it via NuGet. Also check if you did not mix 32bit R with 64 bit c#.
Using the Helper-functions of 1.5, initialization is:
Helper.SetEnvironmentVariables();
engine = REngine.CreateInstance(EngineName);
engine.Initialize();
# Assuming you want to catch the graphic window, use my RGraphAppHook
# on the rdotnet site http://rdotnet.codeplex.com/workitem/7
cbt = new RGraphAppHook { GraphControl = GraphPanelControl };
I added as reference 3 dll's: Google.Apis , Google.Apis.Translate.v2 , System.Runtime.Serialization
In Form1 i have one line:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
Translator.translate(new TranslateInput());
}
private void Form1_Load(object sender, EventArgs e)
{
}
}
}
Now the error the exception is on the first line in the class Translator:
The line that throw the error is: var service = new TranslateService { Key = GetApiKey() };
The class code is:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Net;
using System.IO;
using System.Web;
using System.Runtime.Serialization;
using System.Runtime.Serialization.Json;
using Google.Apis.Util;
using Google.Apis.Translate.v2;
using Google.Apis.Translate.v2.Data;
using TranslationsResource = Google.Apis.Translate.v2.Data.TranslationsResource;
public class Translator
{
public static string translate(TranslateInput input)
{
// Create the service.
var service = new TranslateService { Key = GetApiKey() };
string translationResult = "";
// Execute the first translation request.
Console.WriteLine("Translating to '" + input.TargetLanguage + "' ...");
TranslationsListResponse response = service.Translations.List(input.SourceText, input.TargetLanguage).Fetch();
var translations = new List<string>();
foreach (TranslationsResource translation in response.Translations)
{
translationResult = translation.TranslatedText;
}
return translationResult;
}
private static string GetApiKey()
{
return "AIzaSyCjxMe6RKHZzd7xSfSh2pEsBqUdXYm5tA8"; // Enter Your Key
}
}
/// <summary>

/// </summary>
[Description("input")]
public class TranslateInput
{
[Description("text to translate")]
public string SourceText = "Who ate my candy?";
[Description("target language")]
public string TargetLanguage = "fr";
}
The error is:
Could not load type 'Google.Apis.Discovery.FactoryParameterV1_0' from assembly 'Google.Apis, Version=1.1.4497.35846, Culture=neutral, PublicKeyToken=null'.
Tried to google for help and also tried to change the project type to x64 platform but it didnt help. So i put it back on x86
I have windows 7 64bit visual studio c# 2010 pro .net 4.0 profile client.
Cant figure out what is the error ?
This error as reported in the above-posted messages is due to a local copy in the bin\Debug folder of your solution or project. Even though you attempt to clean your solution, such copies will persist to exist.
In order to avoid this to happen, you have to force Visual Studio to refer to the correct DLL by adding reference paths within a project properties. Unfortunately, if you got several projects within your solutions, you will have to set the reference paths for the projects one after another until completed.
Should you wish to know how to setup reference paths follow these simple instructions:
1.Select your project, right-click, then click "Properties";
2.In the project properties, click "Reference Paths";
3.Folder, type or browse to the right location of your DLL, click [Add Folder].
You will need to perform these steps for as many different locations you may have for each of your DLLs. Consider setting an output path under the Build tab of the same project properties, so that you may output your DLLs in the same directory for each of them, thus assuring you to find all the latest builds under the same location, simplifying forward your referencing.
Note this can only be one reason for this error. But it is sure that is has to do something with a wrong copy of the mentioned assembly.
I'm new to code and most things work, but I can't get this code to run. Can someone help?
I tried using System.Forms but it showed as missing a namespace. When I used using System.Windows.Forms that message went away. It does not let me use both.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
using System.Windows.Forms;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
StreamReader sr = new StreamReader(#"file.csv");
// for set encoding
// StreamReader sr = new StreamReader(#"file.csv", Encoding.GetEncoding(1250));
string strline = "";
String[] _values = null;
int x = 0;
while(!sr.EndOfStream)
{
strline = sr.ReadLine();
_values = strline.Split(',');
if (_values.Length >= 6 && _values[0].Trim().Length > 0)
{
MessageBox.show(_values[1]);
}
}
sr.Close();
}
}
}
There is no such namespace System.Forms, the class you were trying to use (MessageBox) is in System.Windows.Forms. By correcting your using statement, the error went away.
Remember, you must have a reference to System.Windows.Forms.dll in your console app to use this class.
You need to reference System.Windows.Forms.dll in your project. Here is a detailed instruction how to do that.
There is no such namespace as System.Forms there is only a namespace called System.Windows.Forms, wich has the MessageBox class you are talking about. To be able to use it, you need to add a reference to the System.Windows.Forms.dll to to your project (find it in the .NET Tab in the "Add Reference ..." dialog) and it will work. Also note that MessageBox.Show() requires a capital 'S'. Please see below an optimized and fully working version of your code.
using System.IO;
using System.Windows.Forms;
namespace ConsoleApplication7
{
class Program
{
static void Main(string[] args)
{
using (StreamReader sr = new StreamReader(#"file.csv"))
{
while (sr.Peek() >= 0)
{
string strline = sr.ReadLine();
string[] values = strline.Split(',');
if (values.Length >= 6 && values[0].Trim().Length > 0)
{
MessageBox.Show(values[1]);
}
}
}
}
}
}
You try use it in Console application first you should add System.Windows.Forms dll in your references (from .Net reference tab) then use it by adding it's namespace.
I'm a bit confused here. there is no namespace called System.Forms. It's always System.Windows.Forms. And the MessageBox class is defined in System.Windows.Forms
You need to manually ADD a reference to your project for System.Windows.Forms as you are on a console application and not a Windows Application. Just add the reference.
