I am planning an application in Delphi 7 and for argument's sake, let's say that it has a TPageControl in it. I would like each individual TTabSheet to be dynamically loaded because we will be adding to the application over time. The actual application I am writing right now will just be a container for presentation and to give it presence in the system tray.
For instance, one may be a status page, one may be a form to fill out for help, a couple might be for admin access to some system, etc. Each sheet is loaded as a different module (both form and executable code to support it). We will be adding these sheets over time so I need to be able to load these items dynamically and conditionally. Also, being able to add these over time will mean that every time I need to add to or change the application I don't need to redeploy the whole thing, the application can pull in modules as they're added and put on an app server or distribution share -- we have almost 15,000 machines now, and project about 22,000 in a couple years, so deployment is always a problem around here. I know that this can be accomplished with packages and they will share a TApplication object, but using packages assumes I'll be writing all these items in the same language and compiler version so the RTTI will match. In theory, I'd like to be able to use Delphi 2007 instead of Delphi 7, or even VC++ or something else to load into the app. I might not be the only one writing items for this, so I can't enforce a development environment on other teams. So... what are my choices? Ideally I'd like to define a spec for .DLLs so they can be written in any language, but is that even possible to link them in in that way? Would it be clean, anyway? How can I handle intercommunication between items using .DLLs? Or should I just stick to packages written under one version of Delphi? Perhaps there is a solution using some sort of scripting component like Python4Delphi so I can just drop in scripts? Has anybody done anything like this before?
