Good suggestions; we have considered most of them already, and we surely will do something in this area. When we do we will take your suggestions into account.

Very interesting. But I have two suggestions. 1. I can see that you set border=false in the about dialog, but I don't ever think that a button should have a border. So I would set the border false inside the button itself: clauses new():- userControlSupport::new(), generatedInitialize(), localInitia...

I don't think that "version difference" will give this kind of problem. Normally, never versions of "something" implements the "old" components (maybe plus some new ones). Otherwise, upgrading "something" would break other applications. The other applications may of course change behavior anyway whe...

In general PFC code is zero-based. There are however exceptions: Existing code will not change base, because that would break otherwise correct programs When interfacing to external software (mainly Win32 API) the base used in this software will be carried into PFC I.e. where practical possible code...

There are two ways to deal with images in HTML. Either the HTML can link to an image on the Internet. Or the Image can be attached to the mail and the link should then go to the attachment. The first method is often used when sending out news letters etc, because the news letter (and hence the image...

IDE Variables

In the IDE you can define so called IDE variables. Here I will describe one good place to use such a variable. Over time most programmers, teams, companies, etc build up a set of software packages, which are used in many projects. Sometimes these packages are simply copied fro one project to another...

ODBC

Visual Prolog (Commercial Edition) have an ODBC package, which gives access to databases that have an ODBC driver. See also A Simple ODBC Example . Here is a little background information about ODBC. ODBC is an abstraction layer. (There are many abstraction layers in Windows, and the general princip...

Preventing two instances of a program to run simultaneously

You can use this code to prevent a program from being started again when it already runs: class facts okToRunMutex : mutex := erroneous. class predicates okToRun : () determ. clauses okToRun() :- okToRunMutex := mutex::createNamed("SomeStrangeName", false()), not(multiThread_native::wait_timeout = o...

Obviously, I was not clear. I think it is a fine diagram.

I just meant to say, that there is no reason to be scared by its complexity. Because you do not need to grasp it all for any single task. Each task is solved by grasping some fragment of the diagram.

In all its simplicity ;-). Fortunately, you do not have to understand this complete picture in order to use the OO GUI. For certain things you will need one fragment of it for other things another. But you never need to consider it all at the same time. (I have not even tried to validate its correct...
