Description
This tutorial is about writing a dynamic web application using THttpAppSrv component you can find in ICS version 7.
A dynamic web application is one which not only deliver static pages and files, but also dynamic web page.
Source code
Dynamic Pages
A dynamic web page is build on a template html file having special tags such as "<#MyTagName>" which are replaced at runtime by content provided by the application. Usually the content is fetched from a database but can comes from any source. The only limit is the developper imagination !
The component has also special tags to handle tables. Not only html tables, but anything which need to be repeated such as a list content. Using those tags, the developer describe one table row in the template and at runtime, as many rows as needed are created. The developper has full control on the data in each row and of course the number of generated rows.
The tutorial
The tutorial is divided in lessons and each lessons in steps. You must do the lesson in the correct order since most lessons depends on the previous one. In other words, lessons are simply miles stones toward the final
The steps belows correspond to Delphi 2009. You'll have to adapt somewhat the steps according to the IDE you use. The tutorial is OK with all Delphi versions supported by ICS-V7. There could also be some minor differences according to the settings you use for your ide. I'm using undocked layout with floating VCL designer. I'm using a french localized version so the menu items and button captions I give are translated from french to english and could be slightly different than the original english one.
Obvioulsy, you must have ICS-V7 installed within the IDE. When you install ICS, you usually add <ics installdir>\Delphi\VC32 to the compiler search path. If don't do that, you must add that path to every project.
