• Probem With Cross-Domain Silverlight Calls

  Posted: 28 Nov 2008 at 20:54

  I've just been trying to get a Silverlight control to make a cross-domain HTTP POST call using an experimental Silverlight build of XML-RPC.NET. I placed a client access policy file on the root of the server but I was still getting a System.Security.SecurityException when I tried to make the call. I

• XML-RPC From F#

  Posted: 02 Nov 2008 at 20:09

  I recently downloaded the F# September CTP from the F# Developer Center and experimented with some code to make an XML-RPC call using XML-RPC.NET. #light open CookComputing.XmlRpc type Request = { state1 : int; state2 : int; state3 : int; } &

• Code Line Length

  Posted: 06 Oct 2008 at 10:11

  Coding Horror has a piece on Text Columns: How Long is Too Long? The post quotes some research results which probably aren't really all that applicable to code because its not ordinary text and might look a bit strange if right-justified. Still, its a topic worth thinking about. Is there an optimum

• Interdental Brushes

  Posted: 06 Oct 2008 at 10:11

  I've been meaning to mention TePe interdental brushes for a while, to do my bit for the dental hygene of the developer geek world which is not renowned for personal cleanliness. I've never got on with flossing. For me its a bit too fiddly to do every day. As a result I was not cleaning the gaps bet

• Free Wifi on Skye

  Posted: 06 Oct 2008 at 10:11

  Following my recent Skye post Mark Smith at Information Patterns emailed me: You can also get free wifi at the An Tuireann arts centre. They also do good soup which the library doesn't. :-)

• Operation could destabilize the runtime

  Posted: 06 Oct 2008 at 10:11

  I've just come across mention of an XML-RPC.NET problem on the clyx development blog. They have a Community Server installation and were seeing exceptions with this message: Operation could destabilize the runtime. What the? Sorry, could you repeat that? I am so learning to hate that message. A hai

• Outsourcing Lowers Expectations?

  Posted: 06 Oct 2008 at 10:10

  James Robertson discusses a rather provocatively titled piece by James McGovern which describes an anecdote about how outsourcing lowers expectations for individual consultant productivity Perhaps this lowering of expectations applies to in-house developers and not just consultants. After all what

• Postel's Robustness Principle Revisited

  Posted: 06 Oct 2008 at 10:10

  Right now I'm fixing some code, originally written by someone long departed from our development group, which decodes encoded words in email message headers. Encoded words makes it possible to include non-ASCII text in headers. This sample contains two encoded words: Subject: =?ISO-8859-1?B?SWYgeW9

• New Release of XML-RPC.NET

  Posted: 06 Oct 2008 at 10:10

  FYI there is a new release of XML-RPC.NET available. This release fixes the problem I mentioned a couple of weeks ago whereby ASP.NET applications running under medium trust were experiencing VerificationExceptions ("Operation could destabilize the runtime") when using XML-RPC.NET. I build a versio

• The requested FTP command is not supported when using HTTP proxy

  Posted: 06 Oct 2008 at 10:10

  I was using the FtpUpload task from the MSBuild Community Tasks Project and after moving to a different machine started catching an InvalidOperationException with the message "The requested FTP command is not supported when using HTTP proxy". It turns out that only the RETR, LIST, and NLST methods

• Adding a File to the Compile ItemGroup

  Posted: 06 Oct 2008 at 10:10

  I've finally got round to switching from NAnt to MSBuild for building XML-RPC.NET so I'm tentatively finding my way around MSBuild at the moment. One thing I wanted to do was to ensure that builds of the XML-RPC.NET assembly do not have a valid version number when built from within the Visual Studi

• The server committed a protocol violation

  Posted: 06 Oct 2008 at 10:10

  One of the issues involving XML-RPC.NET that turns up fairly frequently is when the library throws an instance of System.Net.WebException with the message ""The server committed a protocol violation". This usually occurs because from .NET 1.1 SP1 onwards the parsing of HTTP responses became much mo

• DeveloperDeveloperDeveloper 4

  Posted: 06 Oct 2008 at 10:10

  I've registered for DeveloperDeveloperDeveloper 4 on Saturday 2nd December. I missed DDD3 because I was on vacation but I found the first two were well worth attending. From the DDD site: This FREE one day event builds on the success of the previous DeveloperDeveloperDeveloper Days. As before it is

• Functional Style Regex Engine in C#

  Posted: 06 Oct 2008 at 10:10

  Wesner Moise's recent post Hard Problems, Simple Solutions speculates about implementing regular expression matching using a functional style. He points to a regular expression engine in 14 lines of Python and suggests this could be ported to C# using iterators and anonymous functions. Wesner write

• XML-RPC Server Using HttpListener

  Posted: 06 Oct 2008 at 10:10

  I've had a handful of requests from people who want to use the .Net System.Net.HttpListener class as the basis for an XML-RPC server implemented using XML-RPC.NET. Acquiring the request synchronously via the HttpListener GetContext method, the top level code could look like this: using System; usin

• Contract Name Not Found In List Of Contracts

  Posted: 06 Oct 2008 at 10:10

  I have just started to dive into ">Windows Communication Foundation. Long overdue I know. One beginner's tip is that if an instance of InvalidOperationException is thrown when you try to create your service host and the exception's message is something like this: The contract name 'TestContract' co

• imeem, Mono, and Mac OS X

  Posted: 12 Feb 2006 at 12:19

  Yesterday I installed a Mac client - imeem - which uses Mono. The snapshot here is from Kevin Lim's blog where he posted about the imeem Mac beta a few weeks ago. I came across imeem via a post by Miguel de Icaza in which he links to an interview with imeem founders Jan Jannink and Dalton Caldwell

• Width-based layout

  Posted: 10 Feb 2006 at 07:03

  I moved my sidebar to a separate page to make enough room for wide blog posts without requiring a very wide browser window. Colly Logic uses a width-based layout which positions the third column according to the width of the browser window.

• Blog on windbg and SOS

  Posted: 10 Feb 2006 at 05:47

  John Robbins points to Tess Fernandez' blog If broken it is, fix it you should. To quote Tess: This blog is intended to help people that develop applications with the .net framework resolve issues on production system, mainly using Windbg.exe from http://www.microsoft.com/whdc/devtools/debugging/de
