Elementary PzlStudio

Автор: Виктор Юхтенко

Elementary PzlStudio is the the Development Environment supporting the elementary operations related to the pzl-technology. The Elementary PzlStudio gives the possibility to include the pzl-system to the applicaions, created by the Visual Prolog programming system and to gerister pzl-components.

Elementary PzlStudio is not fully autonomous tool. The functionality of the Elementary PzlStudio is coordinated with the IDE of the Visual Prolog system. So the generating and the updating of the source code files and projects is done by the Elementary PzlStudio and the compilation of projects and debugging must be done by the IDE of the Visual Prolog Programming system.

Important! Elementary PzlStudio manipulates by components considering them as the combined packages, representing original components and their proxies same time. Elementary PzlStudio modifies the projects files in the following cases: while adding the Pzl-system to the existing applicaion while creation the pzl-container while adding and removing the component to(from) the pzl-container Before the execution of the operations listed above and after they complete it is recommended to build the project using the IDE. While the building (compiling) the proect after you have added any package (class), which is expected to make a call to any Pzl-component, you must refuse' the proposal of the IDE to include the pzl-component to the given project. The inclusion of these new pzl-components must be done using Elementary PzlStudio only. Adding and removing the pzl-components to(from) the pzl-containers makes the coordinated changes in several parts of the Project. It is not recommended to perform these operations using the IDE. It is possible to perform these operation manually using the IDE, but it needs to know all details of the coordinated updates.

Elementary PzlStudio Overview

Elementary PzlStudio is the application whritten using the Visual Prolog programming language and PzlStudio based on the Pzl-technology.

The operation calls are made using the menu and the Tollbar. The list of the operations, which can be preformed using the Elementary PzlStudio and short comments are placed below.

Most of tools of the PzlStudio are represented as forms, where the options and properties may be set and operations may be called to the execution.

The Message Window is the output stream and all tools may send the messages to the Message Window. The Message Window may be closed. To open the Message Winodw again the menu Item View/Messages must be used.

Usually the latest layout of the form is stored in the Windows registry. All current properties of the PzlStudio tools are stored there also.

The example of the status of the Elementary PzlStudio is shown below.

Setting Basic Options

Before you will start to use the Elementary PzlStudio it is recommended to make some settings, which relate to the further operations. The options are: the company name, the author's name, directories etc. These settings will be stored on your computer when you will end the use of the program. You may change the settings at any time you wish

Adding the PzlPort to the application

Elementary PzlStudio has no feature to create new executable applications projects, which contain the pzl-system embedded. But Elementary PzlStudio gives the possibility to include the pzl-system into any application project created before.

If your project exists, then it is ready to include the pzl-system to that project. Just compile it and save before(Ctrl-S).

There is no need to close the project in the IDE before you are going to add the pzl-system to it – it is enough to save it (Ctrl-S).

When you have the applicaion wich is expected to run using the pzl-technology, then you need run Elementary PzlStudio and make adding the pzl-system to that application. This operation adds all needed parts of the pzl-system to the project.

Coming back to the IDE you may compile the application.

Creation of the Pzl-Container

The pzl-container is the place, where pzl-components are stored. In that sense the main application and the DLL are pzl-containers.

The pzl-technology supposes that the main executable application gets the features of the pzl-container, when it gets the features of the pzl-Port. Thus performing the operation of adding the pzlPort to the executable application, we create the pzl-container of the executable application.

That is why the Elementary PzlStudio has no operations to create the pzl-container at the main executable application. The operation creation of the pzl-container means the creation of the DLL, which is the pzl-container.

It is possible to create the project, which corresponds to the dll-container, manually using the IDE. This is not recommended, because of it needs the knowledge of the details of the pzl-container structure. Instead the Elementary PzlStudio proposes the very easy operation to create such a project.

After invoking the operation it needs to fill the form with the basic features of the pzl-container and by one clicking the button you get the pzl-container. This container you must open using the Visual Prolog IDE and build it.
