In most cases you will get a Windows Server that is configured with .NET 3.0, so you will first have to install .NET 3.5 on it in order to use WCF. This is not so difficult, but you need to have the right configuration. From 3.0. .NET 3.5 does not install automatically. You have to make sure that you have Windows Installer 4.5 installed, which you can find here http://www.microsoft.com/DOWNLOADS/details.aspx?displaylang=en&FamilyID=5a58b56f-60b6-4412-95b9-54d056d6f9f4

.NET 3.5 can (redistributable package) be found here http://download.microsoft.com/download/6/0/f/60fc5854-3cb8-4892-b6db-bd4f42510f28/dotnetfx35.exe

Configure ASP.NET and WCF for IIS 6.0

Next, open a command line window and go to the Microsoft.NET directory (typically C:\Windows\Microsoft.Net\Framework or C:\Windows\Microsoft.Net\Framework64).

• Go to the v2.0.50727 dir and run aspnet_regiis -i
• Go to the v3.0\Windows Communication Foundation dir and run ServiceModelReg -i
• Make sure that ASP.NET 2 Web Service extensions are allowed, otherwise you will get a 404 error when opening an svc file.  In the IIS management console, click [Web Server Extensions] and make sure that ASP.NET v2.0.507272 is set to [Allowed]

Configure the host header in order to publish the correct host on the svc web page: open the IIS management console, right-click your website, select [Properties] and on the [Web Site] tab click the [Advanced ...] button.

Web Site Properties

This brings up a new dialog. Click the ip-address for wgich you want to change the identification from localhost to the web site’s ip-address and click the [Edit ...] button.

Advanced Web Site Identification

Now you can edit the [Host Header value] field. Click [OK] to accept the changes.

Edit Web Site Identification

Configuring Postgres to allow your website to access your databases

If you followed the described procedure, you change your website’s id for some applications from “localhost” to whichever ip-address you are using. It took me some time to figure out what was going on, but apparently Postgres complains about access rights, not configured in pg_hba.conf. So if you want to do this, make sure you add an entry in pg_hba.conf, for example:

host all all 192.168.1.1/32 password

this will allow the host with the IP-address 192.168.1.1 to access postgres using password credentials.

The solution to this problem can be found here:

http://www.velocityreviews.com/forums/t29443-cannot-access-internet-while-connected-thru-vpn.html

1. Bring up the properties of your VPN connection and select the [Networking] tab.
2. Select the Internet Protocol Version 4 or 6 Properties and click the [Advanced] button.
3. Make sure that [Use default gateway on remote network] is not checked.
4. Click the [OK] button to save your settings.

Here’s a list of issues:

1. R requires Administrator rights when you install it (as described in the R Administration guide). This also applies when you want to install add-ons. R itself does not have these permissions, so if you install an add-on from within R, you will get an “access denied” error (to install an add-on, you can use the R gui,  Packages->Install package(s) …). A workaround is to make the R program directory writable to everyone. Maybe you can also try to run R itself as administrator when you need to install a package, but I haven’t tried this yet. This would probably be a better solution.
2. Anyway, on windows, the install procedure is not actually an install procedure. You only get a zip file in a temporary directory. So to really install an add-on, you need to copy the extracted add-on folder and copy it to the Rlibrary. Note that this also requires write access to the R installtion folder.

Here’s a summary of what you need to do to get R working:

1. Download the rscproxy package http://www.freestatistics.org/cran/bin/windows/contrib/r-release/rscproxy_1.2-0.zip, unzip it and install the rscproxy directory in your Rlibrary directory.
2. Download R_Scilab_DCOM3.0-1B5.exe from http://www.freestatistics.org/cran/contrib/extra/dcom/R_Scilab_DCOM3.0-1B5.exe (you coulds also use another mirror), and install it.
3. To use R, add a reference to your C# project to STATCONNECTORCLNTLib, StatConnectorCommonLib, and STATCONNECTORSRVLib (this is to get full functionality, for the client to work, you only need STATCONNECTORSRVLib).
4. Use the STATCONNECTORSRVLib.StatConnectorClass to interface with R.

Here’s some example code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using NUnit.Framework;

//COM references
using STATCONNECTORCLNTLib;
using StatConnectorCommonLib;
using STATCONNECTORSRVLib;
using System.IO;

namespace RConnector.Tests.Integration
{
    [TestFixture]
    public class TestConnectivityWithR
    {

        [Test]
        public void Open_Close()
        {
            StatConnectorClass RConnector = new StatConnectorClass();
            RConnector.Init(“R”);
            RConnector.Close();
        }

        [Test]
        public void Send_Receive_Data_()
        {
            StatConnectorClass RConnector = new StatConnectorClass();
            RConnector.Init(“R”); 
           // Data we are going to pass
            int n = 20;
            // Cast C# type to R type
            RConnector.SetSymbol(“n1″, n); 
            // The cast value n to n1 is now being used in R
            RConnector.Evaluate(“x1 <- rnorm(n1)”); 
            // We get back the value of x1, but it needs to be cast
            // to an array of doubles
            object o = RConnector.GetSymbol(“x1″);
            double[] random = (double[])o;
            foreach (double d in random)
            {
                Console.WriteLine(d);
            }
        }

StatConnectorClass RConnector = new StatConnectorClass();
RConnector.Init(“R”);
double[] input = new double[3][];filling the array and then doing:RConnector.SetSymbol(“input”, input);

will throw an error, even if all the double[] arrays in input have the same length. Instead, you need to use the Array class.

StatConnectorClass RConnector = new StatConnectorClass();
RConnector.Init(“R”);
Array mySafeArray = Array.CreateInstance(typeof(double), 5, 2);for (int i = 0; i < 5; i ++)
{
     for (int j = 0; j < 2; j++)
    {
        mySafeArray.SetValue(i * j, i, j);
     }
}
RConnector.SetSymbol(“input”, mySafeArray);

SQL Server (Express Edition) is not configured by default to accept remote connections, so you need some configuration changes.

Here’s how to do it:

Unfortunately, aspnet_regsql kept complaining. The cause was something really trivial (the database instance name was missing in the GUI). Just fill out the database name + instance and all will work well, as described here:

http://blog.krisvandermast.com/ProblemsWithAspnetregsqlASPNETSQLServerSetupWizard.aspx

It took me quite some time to figure this out until I added an empty <prop/> element and Trados 6.5 complained about an illegal token.

So this is the code to create an empty Tmx file – note that I have all my element names and attribute names in separate classes in order to not make typo mistakes:

XDocument m_XDocument;

m_XDocument = new XDocument();
m_XDocument.Declaration =
new XDeclaration(“1.0″, “utf-8″, “yes”);
m_XDocument.Add(
     new XElement(TmxElements.Tmx, 
          new XAttribute(TmxAttributes.Version, “1.4″), 
               new XElement(TmxElements.Header, 
                    new XAttribute(TmxAttributes.CreationTool, “Your.Tool.Name”), 
                    new XAttribute(TmxAttributes.CreationToolVersion, “1.0″), 
                    new XAttribute(TmxAttributes.SegType, TmxSegmentTypes.Sentence), 
                    new XAttribute(TmxAttributes.O_Tmf, “TW4Win 2.0 Format”), 
                    new XAttribute(TmxAttributes.AdminLang, CultureInfo.GetCultureInfoByIetfLanguageTag(“EN-US”).IetfLanguageTag), 
                    new XAttribute(TmxAttributes.SrcLang, sourceCultureInfo.IetfLanguageTag), 
                    new XAttribute(TmxAttributes.DataType, “rtf”), 
                    new XAttribute(TmxAttributes.CreationDate, DateTime.Now.ToString(“yyyyMMddTHHmmssZ”)), 
                    // Here is the empty element!
                    new XAttribute(TmxAttributes.CreationId, Environment.UserName), string.Empty), 
                    new XElement(TmxElements.Body)));

I followed the example from the documentation, set up a POCO class and wrote my mapping file correctly, but as it turned out. I kept receiving error 42P01 which states that relation “n” does not exist.

The error had nothing to do with a non-existent table, but with a configuration file example on:

http://www.hibernate.org/361.html#A6

The solution to the problem is on the same page (if you look well enough, that is):

http://www.hibernate.org/361.927.html

The connection string should read “database=” instead of “initial catalog=”
Unfortunately the example has not been updated at the time of writing.

So here is a corrected version

<?xml version=”1.0″ encoding=”utf-8″?>
<hibernate-configuration  xmlns=”urn:nhibernate-configuration-2.2″ >
    <session-factory name=”NHibernate.Test”>
        <property name=”connection.provider”>NHibernate.Connection.DriverConnectionProvider</property>
        <property name=”connection.driver_class”>NHibernate.Driver.NpgsqlDriver</property>
        <property name=”connection.connection_string”>
            Server=localhost;database=nhibernate;User ID=nhibernate;Password=********;
        </property>
        <property name=”dialect”>NHibernate.Dialect.PostgreSQLDialect</property>
    </session-factory>
</hibernate-configuration>

The following pages provide a solution:

Here’s a description of the problem:

http://www.vistax64.com/vista-performance-maintenance/142155-start-menu-office-2007-shortcuts-have-stopped-working.html

and here’s how to get things working correctly again by using an Application, called ShellExView:

http://windowsxp.mvps.org/slowrightclick.htm

In my case the KDiff3 shell extension seemed to cause the problem. By disabling the extension I got my shortcuts back. I notified the development team.

I stumbled upon it by looking for a “final” keyword (as in Java). Having read the article it is clear why there is no such thing in C#.
