2008/09/17 - Vote for SOAP v1.2 client support in QC
In case some of you haven't read the Delphi 2009 readme.htm yet (also in the Release Notes), it mentions the following:
SOAP Server Notes The Win32/native SOAP server is currently on the Deprecated list and is classified as "Other Consideration: Need alternative." If you want a document/literal server, you should build your SOAP server using Delphi for .NET (RAD Studio), which supports the SOAP specifications that are supported by the .NET framework.Although I can understand that (a bit) for the SOAP server side, I would really want some extended Win32 SOAP support for clients, specifically for SOAP v1.2, MTOM (Message Transmission Optimization Mechanism) and in the end also interoperability for WCF servers.
I blogged about it and opened a QC feature request report, and invite everyone who also cares about Win32 SOAP (client) support to vote for this report.
2008/08/04 - Delphi for Win32 SOAP Exceptions
In this article, I'll demonstrate how Delphi for Win32 Web Services can create and handle SOAP Exceptions (as well as custom SOAP Exceptions) - with a little fix from CodeGear's Jean-Marie (Bruneau) Babet. Thanks!
2007/09/12 - Introduction to WCF Programming in Delphi
The Introduction to WCF Programming in Delphi session starts from WCF object model basics, including message-based communication stack, service contracts, endpoints, transports, exchange patterns, and interoperability with Web Services.

Using a simple echo web service, I'll demonstrate how the Delphi and Kylix clients can connect to and interact with the C# web service.
In the second article, I'll show how web services written in Delphi can be consumed and used by C# on the .NET Framework. Extending the simple echo web service, I'll demonstrate how the C# client can connect to and interact with the Delphi web service.
2003/09/01 - ASP.NET Web Services and Sessions
My latest article in Hardcore Web Services is about ASP.NET Web Services and Sessions. By default, Web Services are stateless. However, that doesn't mean that they can't maintain state. Although you'll often be told that a stateful Web Service is a Bad Thing, it doesn't hurt to know that the possibility exists. In this article, I show how to add state management and session support to your Web Services, explaining what to do and what not to do, so you can decide for yourself whether, where, and when you want to use this ability.
2003/08/22 - C++Builder 6 meets C# ASP.NET Web Services

2003/05/09 - Dr.Bob Examines C# Web Services
In this article, I'll show how web services can be written and consumed in C# and using nothing but the .NET Framework SDK (i.e. without using a C# IDE at this time) to demonstrate the syntax and techniques using the C# language.
2003/05/05 - Hardcore Web Services
You know Web Services will cross tools and platforms, but have you actually done it? In this article for Hardcore Web Services, I show how Web Services written in C# can be consumed and used by Borland's Delphi (on Windows) or even Kylix (on Linux). Using a simple Echo Web Service, I show how the Delphi and Kylix clients can connect and interact with the C# Web Service.
2003/04/14 - Dr.Bob Examines ASP.NET Web Services
Two months ago, we explored the Delphi for .NET as scripting language for ASP.NET applications. This time, in my April 2003 Dr.Bob Examines column, I'll show that apart from producing server side scripted web pages, Delphi for .NET and ASP.NET can also play an important role when it comes to .NET web services.

2003/03/03 - RemObjects SDK in The Delphi Magazine
My Under Construction column in the March issue of The Delphi Magazine is about Distributed Apps On The Cheap, examining how to use the RemObjects SDK to build multi-tier applications in Delphi 7 Professional.
Important Note: In this article, I suggested that Delphi 7 Professional developers could purchase a DataSnap licence to be able to deploy the applications that make use of the ClientDataSet and DataSetProvider. Unfortunately, it turns out that it is not possible to purchase a DataSnap licence for Delphi 7 Professional. Technically, the presence of ClientDataSet and DataSetProvider in the product makes it possible to create a multi-tier application with Delphi 7 Professional (plus a third-party tool like RemObjects SDK) using these components, but it would not be legal to deploy such an application because the required runtime licence for DataSnap cannot be obtained without purchasing Delphi 7 Enterprise or Architect. I apologise for any confusion caused.
2003/01/29 - DSOAP discontinued and available for free
After the creation of the RemObjects SDK, further development on the DSOAP toolkit has been discontinued. For a better remoting solution that doesn't depend on the Microsoft SOAP Toolkit or COM, make sure to check out RemObjects SDK and my detailed review.
2003/01/15 - RemObjects SDK 1.0.7 and Trial Version
Version 1.0.7 of the RemObjects SDK is available for download, and contains - among other new features - Kylix 3 support, which was one of my wishes in the RemObjects SDK review I wrote for the UK-BUG Borland User Group Developer's Magazine.

2002/06/13 - Results of Borland Web Services Survey
Borland has released the results of the customer survey conducted at BorCon 2002 last month. No less than 80% of respondents are either currently using Web Services or are planning to use them in the very near future. Borland customers are using Web Services across many industries, but of those surveyed, a surprising 24% are in healthcare, 14% are in finance, and 14% are in government. These customers use Web Services for image retrieval, online tax preparation, e-filing for tax returns, 401K administration, medical record retrieval, e-learning, human resources facilitation, e-commerce, and financial aid, among others.
Contrary to what other reports have indicated; only 19% said that security was a main barrier to using Web Services. Of the survey respondents, 36% were from large enterprises, 24% were individual developers and 24% claimed "other." Small to medium enterprises and value added resellers comprised 10% and 7% respectively.

Just published in the UK-BUG Borland User Group Developer's Magazine, my latest Dr.Bob Examines article investigates the tools and techniques to use (consume) Web Services with JBuilder 6 Enterprise and the Borland Web Services Kit for Java. In this paper we'll consume a Web Service previously written in Delphi 6 (and also available in Kylix 2) to demonstrate the interoperability between JBuilder 6 and Delphi/Kylix (using SOAP).
2002/02/22 - Delphi 6 and Kylix 2 Web Services
When Borland shipped Delphi 6 in May of last year, one of its new features was support for SOAP - most notably in the form of Web Services. Kylix 2 is now also available with the same capabilities, and in an article for Web Services Journal, I demonstrate the ease of use of Delphi 6 and Kylix 2 by developing a Web service in a Delphi 6 server (running on Win32) and consuming it in a Kylix 2 client running on Linux. The example I'm using is the IRoman Web Service, converting roman numerals into integers and back.
2002/02/20 - Delphi 6 Update 2
Delphi 6 Update 2 has just been released. This is an important update, since it not only fixes a number of defects, but also makes sure that Delphi 6 and C++Builder 6 can co-exist on the same system! The Borland Community article contains the list of fixes.
A large number of SOAP issues have been resolved, and we can now write SOAP Clients with Delphi 6.02 Professional (but not SOAP Servers, for which you still need the Enterprise edition).
2002/02/13 - Borland's .NET Strategy
Borland has announced its .NET Strategy, which can also be read on the Borland Community website.

2002/01/24 - The Chess WebService is Back!
The Chess WebService IBorlandChess, implemented by Borland Software Engineer Dan Marinescu, is back in the new domain www.danmarinescu.com and listed on xmethods. The Chess WebService implements an extremely scalable SOAP interface to a fully featured, high performance (competition level) Chess Engine, which is completely stateless.
The Chess WebService is currently written in Delphi 6. Soon, we will have the very same WebService written in Kylix 2 & C++Builder 6 - very soon!.
I've check out the source code for the client and server, and played a few games with the client binary, and am (again) very impressed by this amazing WebService. Well done!
2002/01/18 - Kylix 2 IEuro Web Service
A small bug was fixed in the the Kylix 2 IEuro Web Service (converting 12 European currencies to € and back). The IEuro web services is implemented in Kylix 2 Enterprise and listed on both XMethods and Salcentral.

There is a nice SOAP resource available on CD-ROM from Borland and Referentia, called The Borland e-Learning Series, which has a new title for Web Services written by Lino Tadros (and with me as Technical Editor, so I know it's good :-).
2001/11/26 - Kylix 2 Enterprise "IEuro" Web Service
I've deployed my first Kylix 2 Enterprise web service: with the IEuro interface (converting 12 European currencies to Euro and back). The IEuro interface contains two methods: FromEuro and ToEuro, both having a WideString as first argument (the European currency - FIM, ITL, NLG, ESP, BEF, ATS, LUF, DEM, FRF, IEP, PTE, and GRO) and a "double" amount as second argument, returning the result as "double" as well.

2001/09/21: Kylix 2, C++Builder 6 & JBuilder 6
On Monday, at the opening keynote of the European Borland Conference in London, some interesting pre-announcements were made by Nigel Brown of Borland UK. Nigel Brown showed a time-line and mentioned the upcoming releases of Kylix 2 (Q4 2001) and JBuilder 6 (Q4 2001) and the Borland Enterprise Studio for Java version 3 (with JBuilder 6) and a new Borland Enterprise Studio for Windows (containing both Delphi and C++Builder), both for Q1 2002.
Nigel Brown called Delphi 6 the first development environment from Borland with SOAP and web services support, but made it clear that this [SOAP and web services] would be available in the next versions of JBuilder (6) and Kylix (2).
Also, when asked, Jason Vokes (from Borland UK) confirmed that the next release of C++Builder is also in the works, with SOAP and web services support, of course. There were no comments on C++Builder for Kylix (or Kylix for C++), however.
No press releases or further information had been made available, but the announcement itself came from a reliable source (Nigel Brown and Jason Vokes, Borland UK), and was made at a public conference.
2001/09/03 - Delphi Developers Guide to XML
Delphi Developers Guide to XML by Keith Wood, published by WordWare is designed for the Delphi developer who wants to learn about XML; covering all aspects of utilizing the power of XML with Delphi. This book provides a solid introduction to the technologies that make up XML and its related specifications. In-depth coverage of the Document Object Model (DOM) includes investigation of the basic specification and three implementations: Microsoft's DOM, CUESoft's DOM, and Open XML's DOM. Similarly, both Microsoft's version and a native Delphi implementation are described for the Simple API for XML (SAX). Generating XML documents is detailed using simple text, Delphi's Web modules and XMLBroker, each of the DOMs, and SAX. Developing applications that make use of XML is also covered, including XSLT and SOAP examples.

2001/04/08 - Dr.Bob Examines .NET and C#
In this Dr.Bob Examines column I'll share my first experiences with Microsoft Visual Studio.NET Beta 1, and especially C# (writing a classic demo).
2001/03/31 - Building Delphi 6 Applications
Available from Amazon.com (with a discount): the first book about Delphi 6 (or at least the first title that appears with Delphi 6 in the title - even before Delphi 6 itself is announced or available): Building Delphi 6 Applications by Paul Kimmel.
I have ordered this book myself, received it yesterday, and can only say one thing: There is no real Delphi 6 information (a few mentions of Delphi 6 Beta 2 features), and even for a "regular" Delphi 5 book, it never raises above the "intro" level. The topics of the chapters are interesting, but the content itself is very disappointing.
