Topic Source Code 114 .NET Assemblies, Security And AppDomains Bob Swart explains the problems caused by assemblies that include P/Invoke calls, and explains how to overcome them. He then moves on to demonstrate how to dynamically load assemblies and use Reflection to get class types, methods and fields from these assemblies, plus unloading assemblies using an AppDomain and a wrapper. const114.zip 46.644 bytes 113 .NET Command-Line Tools, Delphi 2005 IDE Support And Assembly Hell Bob Swart describes the use of some .NET command-line tools that can be helpful when integrated into the Delphi 2005 IDE. He also discusses some of the less visible gotchas in Delphi 2005 and the problems you will encounter using assemblies developed in one version of Delphi with a different version. const113.zip 1.336 bytes 112 Delphi 2005 Bob Swart reviews the latest version of Delphi, with both Win32 and .NET support in one IDE, plus C# as well as Delphi language compilation! Could this be the best ever Delphi? Check out Bob? review and find out! n/a 111 Big Brother Is Watching You Bob Swart describes how to take control over the running of an application; specifically, to control how frequently MSN Messenger is used and for how many minutes in each day: very handy if like Bob you have kids who are addicted to MSN, or perhaps to their favourite game. const111.zip 6.708 bytes 110 DataSnap and .NET Bob Swart shows how to use DataSnap with .NET: connecting to a DataSnap server for Win32, built using Delphi 7, from a .NET client in Delphi 8, and talking to Linux from .NET using a Win32 gateway DataSnap server to overcome the current lack of SOAP support on the .NET end! const110.zip 50.790 bytes 109 Webcam Publishing Bob Swart wanted to find an easy way to keep in touch with the family while he? away, so he developed some nifty applications to make use of a few webcams: capturing, publishing and retrieving images, using a variety of Win32 and .NET technologies. const109.zip 19.633 bytes 108 Delphi Language Enhancements Bob Swart outlines the additions to our beloved language that arrived with Delphi 8, and discusses which of these might make the transfer from .NET to Win32 in a future Delphi version. const108.zip 5.236 bytes 107 Delphi 7 Update 1 Bob Swart takes a good look at Update 1 for Delphi 7 to see what Borland has been doing to help the Win32 developers amongst us! Want to know if some annoying bug has been fixed ?read this article! n/a 106 Intraweb for .NET Bob Swart examines IntraWeb for .NET, providing an overview and comparing it to ASP.NET (with Delphi 8 for .NET). He focuses on login and authorisation/authentication, database support, session and state management, navigation, deployment, and finally custom components (including third-party components). n/a 105 ASP.NET User and Custom Components Bob Swart explains the two ways to implement custom ASP.NET controls: adding them to an existing ASP.NET web forms application (in which case they are called ASP.NET user controls), or creating a complete new package for them (which is called a Web Control Library) and thereby ending up with an ASP.NET custom control. In this month? column Bob describes and demonstrates both techniques. 105 ASP.NET Security Bob Swart shows how authorisation and authentication work in the .NET Framework, and puts the theory to good use to demonstrate how to limit access to areas of your website with some straightforward ASP.NET code, making use of ASP.NET forms authentication. const105.zip 29.550 bytes secur105.zip 16.280 bytes 104 MDA And Enterprise Core Objects Bob Swart explains MDA, which stands for Model Driven Applications, and how we can use the Architect edition of Delphi 8 for .NET to put MDA into action with Enterprise Core Objects (ECO). const104.zip 15.678 bytes 103 Delphi 8 For .NET And ASP.NET Web Services Bob Swart discusses ASP.NET web services, considered by many to be the best part of the .NET framework. He also explains how to migrate your existing Delphi web service engines to ASP.NET in such a way that the resulting project can be compiled with both Delphi 7 and Delphi 8 for .NET. const103.zip 64.266 bytes 102 Delphi 8 For .NET And Data Access Technologies Bob Swart discusses several solutions for data access on .NET, both for VCL applications and those which do not use VCL for .NET, and explains when to use what, including an introduction to ADO.NET. const102.zip 9.292 bytes 101 Delphi For .NET, ASP.NET And DB Web Controls Bob Swart starts with the Borland Data Providers for .NET, an open layer on top of ADO.NET providing support for multiple databases, and then uses them in an ASP.NET web forms application, using the new DB Web controls. const101.zip 12,913 bytes 100 RSS With Delphi For .NET Bob Swart continue his coverage of RSS channels and feeds, but this time using Delphi 8 for .NET. He focuses on Delphi 8? XML and database support as it relates to this project, as well as the migration path for existing VCL applications. const100.zip 20,809 bytes 99 RSS Channels and Automatic Feeds Bob Swart focuses on RSS channels and automatic feeds. He explains what RSS is, how it can be of benefit to RSS readers as well as the publishers, and (specifically in this issue) how to automatically produce RSS XML documents from a database, resulting in a database-driven content generator with an RSS channel to publish a table of contents. constr99.zip 8,633 bytes 98 dbExpress And QualityCentral Bob Swart uses the normalised data model developed over the last few issues and implements it using dbExpress to talk o InterBase. Along the way a number of problems arise and Borland? QualityCentral resource proves useful in solving these to get a working end result. 98 Moving To Delphi For .NET Today! Bob Swart shows how to modify your Delphi projects to get them working with the Delphi for .NET preview compiler and so be ready for the full-blown Delphi for .NET when it arrives. constr98.zip 20,720 bytes 97 InterBase 7.1 and the Borland Data Providers for ADO.NET Bob Swart describes how to use the recently introduced Borland Data Providers For ADO.NET in the Delphi for .NET command-line preview compiler to access InterBase databases. 97 Effective ClientDataSets Bob Swart uses the ClientDataSet to implement the database design discussed last month, revealing some useful tips and showing how theoretical design sometimes needs to be tweaked to arrive at a practical solution. BDP97.zip 2,374 bytes constr97.zip 15,106 bytes 96 Database Normalisation Bob Swart provides some helpful database design rules, formally called database normalisation, but you can also call it common sense! Most developers have worked with databases in one way or another, maybe also designing databases and creating tables, but how many of us have taken the trouble to ensure our designs are efficient and effective? n/a 95 ASP.NET Web Services Bob Swart shows how to build, test and deploy a Delphi for .NET web service on the .NET framework, as well as how to import such web services with Delphi 7 in order to illustrate some potential compatibility issues between Delphi 7 (Win32) and Delphi for .NET. constr95.zip 9,766 bytes 94 Delphi For .NET, ODBC.NET, ADO.NET And MySQL Bob Swart shows how to use MySQL with the Delphi for .NET preview compiler, through both ODBC.NET and (for greater performance, but at a cost of some cash!) ADO.NET. constr94.zip 4,803 bytes 93 DCon Planning With Delphi (for .NET) And ASP.NET Bob Swart continues to work on his schedule-choosing web application for DCon 2003, but this time he? using Delphi as an ASP.NET scripting language, courtesy of the Delphi for .NET preview compiler (and a lot of head scratching to work round the problems which came to light...). constr93.zip 14,794 bytes 92 DCon Planning With IntraWeb 5.1 Bob Swart calculates that with over 40 technical sessions in two days, there are over 100,000 possible ways you can pick and follow the DCon 2003 sessions. Making sure you don急 miss that crucial session may not be easy, so in this column he builds a semi-intelligent planning application with IntraWeb 5.1. constr92.zip 19,161 bytes 91 Distributed Apps On The Cheap Bob Swart thinks it? unfair that developers should have to use the expensive Enterprise editions of Delphi to build distributed applications, so in this article he examines 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. constr91.zip 22,848 bytes 90 MySQL Data Access Libraries Bob Swart evaluates various third-party libraries you can use to get at your MySQL databases from Delphi apps: ZEOS Library, DirectMySQL and TmySQL (all are freeware or GPL), plus Core Lab MyDAC for Windows and finally the microOLAP MySQLDAC components (commercial products). n/a 89 Delphi, dbExpress And MySQL, On The Web Bob Swart takes the MySQL knowledge gained in last month? column and applies it to web app development. constr89.zip 15,200 bytes 88 Delphi, dbExpress And MySQL (free) The BDE has had its day, but some of the alternatives seem very costly (SQL Server at ?,612 for a 10-client version of the tandard product, anyone?). So Bob Swart has been checking out MySQL to see how easy it is to use with Delphi. Oh, and it? either free or very cheap, depending on the licence you choose! constr88.zip 3,219 bytes 87 Delphi 7 SOAP And UDDI Bob Swart describes the changes and enhancements to SOAP in Delphi 7, most notably the UDDI browser, as well as a workaround for an ISAPI SOAP problem. constr87.zip 17,727 bytes 86 Encrypted ClientDataSets Bob Swart shows how to encrypt ClientDataSet files for greater security and also how to use on-the-fly compression and decompression to speed them up as well. constr86.zip 5,056 bytes 85 Transactional Data Modules (2) Bob Swart continues his coverage of MTS/COM , discussing various security issues, as well as debugging techniques and deployment features. constr85.zip 10,900 bytes 84 Transactional Data Modules Bob Swart describes the transactional data module: how to use it to create DataSnap servers, how to connect to it from DataSnap clients, and some of the differences (and benefits) it has compared to using a normal remote data module. constr84.zip 10,364 bytes 83 Real-World WebSnap Techniques Bob Swart continues examining some real-world WebSnap techniques, this month creating localisation options: the ability to dynamically switch display languages within your WebSnap applications. constr83.zip 16,408 bytes 82 Real-World WebSnap Techniques Bob Swart discusses some real-world WebSnap techniques he has discovered in his web application development, including user logins, DataSetAdapter naming conventions, BDE hints and using Amazon's XML support. constr82.zip 24,960 bytes 81 Delphi 6.02 Web Services Bob Swart tells us what's new with SOAP and Web Services in the recent Delphi 6 Update 2 (which is quite a lot, as it turns out!). constr81.zip 15,944 bytes 80 ISAPI Filters, Part 2 Bob Swart continues his 2-part article on writing ISAPI filter DLLs: a really powerful way to do lots of clever stuff on your website. This month, he goes into more details on authentication (password-protected directories to you and me!) and also implements a little page-changing script framework. constr80.zip 10,436 bytes 79 WebSnap Session Management For CGI (free) WebSnap session management using TSessionsService is not available for CGI applications or Kylix web apps, but Bob Swart explains what the problem is, what to do about it, and how he solved it to provide full session management for all web app targets. 79 ISAPI Filters, Part 1 Bob Swart starts a two-parter on writing ISAPI filter DLLs: a really powerful way to do lots of clever stuff on your website, that takes us down to the metal, doing things the (actually not so) hard way without any Snap, Broker or Express tools to help! cgisnap.zip 8,633 bytes constr79.zip 5,914 bytes 78 DataSnap Sockets And Interceptions Bob Swart checks out socket interceptions: peeking into what's happening between the client and the server when you use the SocketConnection component. Bob makes use of the IDataIntercept interface and the TPacketIntercept class. constr78.zip 14,466 bytes 77 Delphi 6 DataSnap and SOAP Bob Swart explains how to build cross-platform (Windows and Linux) and cross-language (Delphi and Kylix) multi-tier applications using DataSnap and SOAP. constr77.zip 14,308 bytes 76 Delphi 6 DataSnap Connections Bob Swart checks out DataSnap connections. There are three new components in Delphi 6 especially written for DataSnap connections (or providers of data), namely the ConnectionBroker, SharedConnection and LocalConnection. Bob explains what they are, plus when and how to use them. constr76.zip 14,308 bytes 75 Delphi 6 WebSnap (3) Bob Swart concludes his discussion of Delphi 6's WebSnap technology (well, for now at least) with various helpful techniques, including details of how persistent sessions work and guidelines for putting them to use in your web applications. constr75.zip 8,704 bytes 74 Delphi 6 WebSnap (2) Bob Swart continues his discussion of Delphi 6's WebSnap technology, covering master-detail relationships and creating user login functionality. constr74.zip 23,529 bytes 73 Delphi 6 WebSnap (1) Bob Swart begins an overview of this new web application development framework introduced in Delphi 6: what it's all about and how to use it. This month Bob shows how to get started and how to use the Web App Debugger application type for debugging. cdebug73.zip 8,692 bytes constr73.zip 180,934 bytes 72 Delphi 6 Web Services (free) Bob Swart checks out Delphi 6's WebSnap, covering WebBroker and InternetExpress, with lots of new features, such as Web Services. constr72.zip 8,097 bytes 71 Kylix Desktop Does CGI Too Bob Swart shows how to create web server applications using just the Desktop version of Kylix (which has just been dramatically reduced in price!), including using dbExpress to develop database web applications. constr71.zip 3,510 bytes 70 WebBroker for Linux Bob Swart shows how we can use Kylix to create web server applications for the Apache web server running on Linux, with the built-in Web Broker technology found in the Kylix Server Developer Edition. constr70.zip 3,072 bytes 69 DataCLX and dbExpress Bob Swart introduces DataCLX and dbExpress: the cornerstone of database access in Kylix and Delphi 6. constr69.zip 545 bytes 68 Data-Awareness and Interfaces Bob Swart discusses data-aware components, using an IDataAware interface to conveniently and easily manage data-aware components. constr68.zip 4,664 bytes 67 VisiBroker 3.3 for Delphi 5 Bob Swart continues his discussion of the new version of VisiBroker for Delphi, this month covering support for special type constructs and CORBA callbacks. constr67.zip 12,061 bytes 66 VisiBroker 3.3 for Delphi 5 Bob Swart explains the goodies available in the latest version of Borland's tool for making CORBA applications easier for Delphi developers, including a new and much improved IDL2Pas. constr66.zip 13,531 bytes 65 Wireless Application Protocol (2) Bob Swart continues his explanation of writing applications that your WAP phone can access, covering the use of WAP images in the WBMP format. constr65.zip 8,723 bytes 64 Wireless Application Protocol (1) Bob Swart has been pushing the envelope of new technology: he explains what WAP is all about and how to create applications for generating the WML XML-like code that WAP phones use. constr64.zip 3,775 bytes 63 Local ClientDataSets (2) Bob Swart continues his examination of TClientDataSet as a small, fast local DBMS, showing how to use XML files as input for ClientDataSets, creating true thin-client applications which can communicate with a server using sockets. constr63.zip 16,354 bytes 62 Local ClientDataSets (1) MIDAS isn't just for multi-tier apps, says Bob Swart, but we can use it as a handy, compact and very fast local database engine, with just one DLL to ship (and no licence fees either!). Bob goes on to show how to use XML to get data into and out of a local ClientDataSet. constr62.zip 7,844 bytes 61 Strings Strings: we use them all the time and know everything there is to know about them, right? Wrong! Bob Swart delves under the hood to explain the various character and string types available in Delphi, how they work and which ones are appropriate to which use. n/a 60 Pooling And Brokering Bob Swart returns to MIDAS 3 to explain Object Pooling and Object Brokering. If your web applications are feeling the strain and you need to share the software load over multiple servers, these technologies could provide just what you need. n/a 59 Delphi 5 Active Server Objects (2) Bob Swart completes his coverage of developing Active Server Objects by looking at the way in which WebBroker and InternetExpress can be used by an Active Server Object. constr59.zip 9,542 bytes 58 Delphi 5 Active Server Objects Bob Swart describes how easy it is to create and use Active Server Objects in Delphi 5 that can be used in web (or intranet) pages created using Microsoft's Active Server Pages scripting language. constr58.zip 5,081 bytes 57 Delphi 5 And MIDAS 3 Bob Swart discusses the new things to be found in MIDAS 3, including stateless remote data modules.
