Project and Analysis

A WinDev project is a set of windows, controls, classes, components, and so on whosepurpose is to create a Windows application.

A WinDev analysis contains the description of the data files.

In most cases, a project is associated with an analysis.An analysis can be associated with one or more projects.

To create the "lovelyeyes" application, create the "lovelyeyes" project.

Source Code Manager (SCM)OverviewTo simplify teamwork, a Source Code Manager is available in WinDev. This Source CodeManager allows several developers to work together on the same project at the sametime and to share elements among several projects.

The elements found in the SCM can be shared:• via a network• via Internet• in offline mode. In this case, the elements requiring specific attention will be chec-

ked out from the SCM when the laptop is connected to the main system for instance.

Operating mode of the Source Code ManagerThe following example presents the Source Code Manager:

If a project element (window, report, and so on) is checked out, this element cannot bechecked out twice.Once the checked-out elements are modified, these elements must be checked in so thatthe modifications can be taken into account by the source project. Indeed, the SCM da-tabase stores a history of all the project elements since their creation.

Whenever an element is checked in, the version number of the source project is incre-mented by 1.

The Control CentersTo optimize the management of your development projects, WinDev gives you the abilityto use the Control Centers. The different Control Centers allow you to:• Manage the requirements of a project, page 17.• Manage the monitoring of a project, page 18.• Manage the bugs and the evolutions requested by the users on a project, page 19.• Manage the business rules, page 20.

The Control Centers use a database (HyperFileSQL Classic or Client/Server). This databa-se is shared among the different tools available in WinDev:

When installing WinDev, the setup program proposes:• to create the database of Control Centers. This database will be automatically crea-

ted in HyperFileSQL Classic format in the specified directory.• to share an existing database of Control Centers.

Project Monitoring CenterThe Project Monitoring Center allows the different contributors of a project to managetheir task schedule. These tasks can be linked to requirements and they can correspondto several projects.

Operating mode of the Project Monitoring CenterOnce all the project tasks have been defined, the Project Monitoring Center takes care ofeverything. Entering the time spent on a task is almost automatic, it requires no specificaction and it generates no particular constraint.When the relevant project is opened, the Project Monitoring Center requests or indicatesthe current task. As soon as a task is completed, all you have to do is indicate that thistask is over and specify the new task.A task can be linked to a project element (window, report, and so on). Whenever the re-levant element is opened, the time spent on this element is counted and stored in themonitoring center. Conversely, the element corresponding to the task you want to per-form can be automatically opened from the task list.Each developer can also view his own task list in the "Project Monitoring Center" pane.

Managing the business rulesWinDev enables you to manage the business rules. A business rule is used to define aspecific operating mode or a specific process. For example: the calculation of a specificVAT rate, the rules for changing the status of a customer, the formula for calculating ship-ping costs, a commercial commission, a discount rate, a decay coefficient, and so on.A business rule can be simple or complex.The business rules can come from:• the specifications (corresponding to the requirements).• the suggestions made by the users of the application.

Dashboard of the projectThe project dashboard is a main element for managing the WinDev projects. The projectdashboard gives an overall view of the progress status of a project.

The dashboard proposes two modes for viewing the project:• The Developer mode.• The Project Manager mode.

In Developer mode, the dashboard is made of:• lights: Everything is OK when the lights are green. The red lights indicate a possible

problem.• lists of elements, giving quick access to the main options of the project.• counters, used to manage the new features, the requests, and so on.

In Project Manager mode, the dashboard is used to get graphic information about the sta-tus progress of the project and about the quality of the project. This mode is recommen-ded when using the Project Monitoring with a management of requirements.

WinDev, WebDev, WinDev Mobile: same projectThe projects are often multi-target projects.For instance, for an ERP system intended for Windows, it is very likely that beside themain application, which will be the backbone of the solution, there will be sales peopleequipped with PDAs or Smartphones, shops that will use mobile terminals to manage in-ventory and that Intranet and Internet sites will be implemented.

Now, this information is grouped in a global project.

Regardless of the product used to create a project, it can be opened by the other pro-ducts.

When a project is opened in a product other than theone where it was created, a wizard is displayed, al-lowing you to create a project configuration specificto the product used.

For instance, if a WinDev project is opened by Web-Dev, you will have the ability to create a project con-figuration named "WEBSite" used to group all theelements required by the WebDev site.

You have now the ability to view the elements ofeach target from each environment. A project in Win-Dev displays the thumbnails of the WebDev pagesand the WinDev Mobile windows for instance. Clic-king a WebDev page from the project editor of Win-Dev opens the WebDev page (WebDev must beinstalled on the computer).

The following elements are also shared: the docu-ments, the modeling descriptions, the components,the classes, and so on.

Project configurationThe project configurations are used to create several different "targets" from the sameproject.From the same project, you have the ability to create:• 2 or 3 executables that do not contain the same elements, with different names, and

so on.• 3 or 4 components• 2 Web services• 1 .Net assemblyYou can work on a specific configuration at any time: the elements that do not belong tothis configuration are grayed in the project graph.

The multiple generation allows you to generate all the project configurations (or some ofthem) in a single operation.

Custom-folders: Organize your projectThe project editor of WinDev is used to represent the entire diagram of the project via theproject graph.With large projects, this representation may be difficult to read. The "custom-folders" areused to improve this representation.A "custom-folder" contains the elements stored by yourself, part of the application for ins-tance: management of customers, management of suppliers, and so on.Some elements can be common to several "custom-folders".It makes it easier to work on part of the application.

Note: The internal components of WinDev can also be used to arrange and organize yourprojects and to share a set of elements among different projects (see ’Internal compo-nent’, page 26).

MDI applicationsIn an MDI application, all the application windows are displayed in the same main win-dow. Two types of windows can be found in the MDI applications:

Non-MDI applicationsIn a non-MDI application, the windows are displayed one after another and they are over-laid. The user can handle the last window displayed. The previous windows are not acces-sible.

MDI parent window: All the other windowsof the application are displayed in this win-dow. This window allows the user to han-dle the main menu of the application.

Window templatesWinDev enables you to create window templates. These templates contain all the graphicelements common to all the windows of your application.The modifications made to a window template are automatically applied to all the win-dows that use this template.A window template enables you to comply with the style book defined for an application.

A window template can be created:• directly ("File .. New .. Window .. Window template").• from the current window ("File .. Save as template").To create a window based on a template, select the template that will be used when crea-ting the window.

Note: The template elements can be programmed in the template itself.

The characteristics of the elements can be dissociated from the template. For example,the position of a control can be dissociated from the template so that the control can belocated somewhere else while it still benefits from the other features (code, style, and soon). We talk of control inheritance. In this case, the elements are identified by a bluesquare.

UMC: User Macro-Code

The UMC mode allows the end user to enter WLanguage code and to graft it onto an exis-ting application.

Let’s consider the following case:An edit window of a customer form requires the presence of an email address but it doesnot check its format. The user wants to check the presence of the "@" character in theaddress.

To enable this feature, specify:• that the project accepts the management of UMC (in the project description).• that this executable accepts the management of UMC (when creating the executa-

ble).

An icon found at the top of the window allows theuser to customize the processes.

The window for configuring the UMC is dis-played. A new action can be added by the userfor this window. In this case, the email addressis checked.

The user enters the WLanguage code. The F1 keyis used to display the help for WLanguage.

Analysis: Structure of the databaseWhen a WinDev, WebDev or WinDev Mobile project uses data files, this project must beassociated with an analysis. An analysis enables you to describe the structures of thedata (files, items, and so on) used in your project.The data model editor enables you to easily create an analysis.

The analysis of a WinDev project corresponds to the LDM (Logical Data Model). The entirestructure and data organization are described: the data is grouped by file. Each file con-tains various pieces of data named item.In the analysis, the description of a file can be linked to a type of file (HyperFileSQL, Ora-cle, and so on).

ble in the database.• variables found in the code of the application (variables global to the window or to

the project or parameters passed to the window).To display this information in a window, the controls of this window must be linked to:• the different items of the database.• the different available WLanguage variables.

The method for displaying and retrieving information is straightforward:• The link between a control and an item or a variable is defined in the window editor,

when describing the control ("Link" tab).• ScreenToFile is used to update the record or the variable with the data displayed on

the screen.• FileToScreen is used to update the data displayed on the screen with the information

saved in the file or with the information saved in the variable.

Browsing table with direct accessA browsing table with direct access is used to directly display the data coming from a datafile or from a query. The structure of the file was described in the data model editor andthe data was entered in the application.Browsing the file is used to display the data in the table. The file is read for each row dis-played: the record read is displayed in a table row.

The data displayed not linked to the file is not kept when displaying the row (value of acheck box column for instance).The WLanguage functions starting with "Table" are used to handle the browsing tableswith direct access. The addition or the deletion of a table row involves the addition or thedeletion of the record in the linked file.

Memory tableA memory table is used to directly display the data loaded in memory. The data is addedto the table by programming (with TableAddLine for instance)

Since the data is found in memory, the table allows you to perform all the operations onthe data (sort on any column, search performed in the columns, and so on).

Browsing table loaded in memoryThe browsing tables loaded in memory combine the benefits of the browsing tables withdirect access and the benefits of the memory tables.The table is linked to the data file but the content of the file is entirely loaded in memory.Sorting and searching are available on all the columns.The data not linked to the file is kept when handling the scrollbar (Check box column forinstance).Since the file’s records are loaded in memory, this type of table is recommended for filescontaining less than 100,000 records (to avoid saturating the memory).

Note: the different fill modes (memory, browsing, browsing loaded in memory) are availa-ble for the list boxes, combo boxes, tables, loopers, and so on.

Universal replicationThe universal replication is used to update databases of same format or databases ofdifferent formats (HyperFileSQL Classic, Oracle, SQL Server, and so on). You can for ins-tance perform a synchronization between a HyperFileSQL database and an Oracle data-base.

The universal replication uses a centralized model: all the databases are synchronizedwith a master database. Then, the master database carries over the modifications to theother databases.

The synchronization can be adapted to special cases. For instance, you have the abilityto retrieve the records concerning a specified product or the records created at a givendate, manage the conflicts, display a setting window, and so on.These changes must be done by programming via HRplFilterProcedure.

3-tier architectureThe 3-tier architecture is designed to separate the 3 "tiers" of an application: UI, proces-ses and data.An application will be made of 3 separate tiers:• a presentation tier,• a process tier,• a tier for accessing the data.

The reason for separating them is to facilitate maintenance and future upgrades of theapplication. This ensures higher security because the access to the database is allowedvia the process tier only. It also optimizes teamwork and multi-target development.

Using an LDAP directoryLDAP (Lightweight Directory Access Protocol) is increasingly used in the business world.The protocol is mainly used to manage the network directories. This protocol defines theoperations for accessing and searching the data, making incompatible systems compa-tible.WinDev provides access to this data.Depending on the information stored in the LDAP directory, you can for instance identifya user when he connects to an application, check the user rights for the application, andso on.

Several LDAP functions are used to process this type of connection and the informationfound in the LDAP directories.

An LDAP directory can also be used by the user groupware available in WinDev.

Transferring files by FTPThe FTP (File Transfer Protocol) is a protocol used to transfer files from a site to anotherremote site. This protocol is used to exchange files via TCP/IP or Internet.

PrincipleTo handle the files found on an FTP server from a WinDev application, you must:

1. Connect to an FTP server (FTPConnect).

2. Transmit and retrieve files (according to the connection mode). For a passive connec-tion, the WinDev application must request the authorization from the FTP server beforeany operation is performed on the server files. You can also:• find out the characteristics of the files found on an FTP server: attributes, size, and

so on.• handle the files found on an FTP server: creation, deletion, and so on.• list the files of a directory found on the FTP server by running a procedure used to

perform a process for each file found.

Managing socketsWinDev provides several functions for advanced socket management.A socket is a communication resource used by the applications to communicate betweencomputers regardless of the type of network.This communication mode can be used, for instance, to communicate between compu-ters connected via Internet.

Different possibilitiesA WinDev application can manage sockets according to different modes:

• Client WinDev application: the application connects to any server and exchanges data via a socket.

• "Simplified server" WinDev application: the WinDev application is a server, exchan-ging information via a socket with a single client computer (WinDev socket recom-mended on the client computer but not mandatory).

• "Standard server" WinDev application: the WinDev application is a server, exchan-ging information via sockets with several client computers.

Principle of a client applicationA client application of a socket server connects to a standard server in order to exchangeinformation via a socket.

Example: A WinDev client application can connect to a standard news server on Inter-net.

Step 1: Connection to the serverTo connect to a server socket, use SocketConnect. This function is used to request a con-nection to the server. The socket is identified by its port and by its address.

Step 2: Exchange of dataOnce two computers have connected their socket, a communication stream is esta-blished between these two computers. These two computers can read and write charac-ter strings on the socket.To read and write on the server socket, the WinDev client application must use Socke-tRead and SocketWrite.

Step 3: End of communicationTo end the communication, close the socket from the client computer with SocketClose.

Managing streams (video-conferencing)To handle the communication streams, WinDev provides:• the Conference control.• the WLanguage STREAM functions.

This enables two users to communicate between themselves. The image and the voiceof each user are transmitted in real time on each connected computer.

Examples of applications that use streams:• video-conferencing• broadcasting a live press conference• and so on.

Caution:

• The current computer and the connected computers must be equipped with a web camera and/or a microphone. If one of the computers is not equipped with a web camera or a microphone, the corresponding image or voice will not be broadcasted.

• Only the video sequences currently broadcasted by the web cameras installed on the connected computers can be viewed. No video file can be viewed.

• Only the sounds currently broadcasted by the microphones installed on the connec-ted computers can be listened to. No sound file can be listened to.

TelephonyWinDev allows you to easily manage the incoming and outgoing phone calls via the tele-phony functions. These functions are used to manage a voice box, an answering machi-ne, and so on in a WinDev application directly.

Required configuration:To be able to use the telephony features, you must have:• a modem.

To save and play back recordings, this modem must have voice support.To identify the caller, the modem must support "Caller ID" (caller ID).

• the Tapi 2.0 protocol. This technology can be used on all the systems; however, you must:- install service pack 4 (or later) if the system used is Windows NT4- upgrade the system if the system used is Windows 95 (can be downloaded from ftp://ftp.microsoft.com/developr/tapi/tapi2195.zip).
