WCF error: "This collection already contains an address with scheme http"

WCF error: "This collection already contains an address with scheme http".

The explanation is that "WCF services hosted in IIS can have only one Base Address".

Easy fix:

Just add the following lines in the system.serviceModel section:

<serviceHostingEnvironment>

<baseAddressPrefixFilters>

<add prefix="http://www.example.com"/>

</baseAddressPrefixFilters>

</serviceHostingEnvironment>

Redirect a page URL in javascript

The following code will redirect a page from index.aspx to the root URL in javascript:

var u = 'http://www.mysite.com/';
if (self.parent.frames.length != 0) self.parent.location=u;
if (self.location != u) self.location=u;//

301 Redirect in ASP.NET / C# Code

If you want to redirect a URL on a permanent basis using ASP.NET and C# code as an alternative to using IIS 6 or IIS 7, you can append the code to the old ASP.NET page.


Response.Clear();
Response.Status = "301 Moved Permanently";
Response.AddHeader("Location", "http://www.newpagelocation.com/");
Response.End();

Hope this helps!

File Access Error .IPX IPIX 360 FILES

If you encounter an error with the message "file access error" when serving IPIX files via a windows server and IIS it is likely that:

1) Your browser has no java support (in this case you will NOT see the IPIX logo)

2) Your IIS Server is not configured to serve these files:

i) Right click the website in IIS > Properties

ii) Select the HTTP headers button

iii) Add a new MIME type with a .IPX extension and MIME type of application/x-ipx

Hope this helps someone - it drove me mad for 2 hours!

Convert Object Array To Dataset

Bind an Object Array to a dataset using the following code.

Code Snippet

using System;
using System.Data;
using System.IO;
using System.Xml;
using System.Xml.Serialization;

namespace BusinessObject.Util
{
///

/// Utility Class for Object Arrays.
///

public class ObjectArray
{
private Object[] _objectArray;

public ObjectArray(Object[] objectArray)
{
this._objectArray = objectArray;
}

public DataSet ToDataSet()
{
DataSet ds = new DataSet();

XmlSerializer xmlSerializer =
new XmlSerializer(_objectArray.GetType());
StringWriter writer = new StringWriter();
xmlSerializer.Serialize(writer, _objectArray);
StringReader reader =
new StringReader(writer.ToString());

ds.ReadXml(reader);
return ds;
}
}
}

How to use the code:

Person[] personList;

personList = Course.GetPersonList();

ObjectArray objectArray = new ObjectArray(personList);Create a DataSet and convert your ObjectArray to a DataSet using the method:

DataSet ds = new DataSet();
ds = objectArray.ToDataSet();
