What's new in Genero Business Development Language, v 2.00

This topic lists features added for the 2.00 release of the Genero Business Development Language.

Table 1. What's new in Genero Business Development Language, Version 2.00
Overview	Reference
The runtime system (fglrun) now uses shared libraries for database drivers; there is no need to link anymore.	See Database driver specification (driver).
The `TYPE` instruction allows to define your own data type structures.	See Types.
New form item types (i.e. widgets): `SLIDER`, `SPINEDIT`, `TIMEEDIT`.	See ATTRIBUTES section.
Database schema files have been extended to centralize form field definition with the new `FIELD` item type.	See FIELD item type.
File management function library provided as loadable extension.	See The Path class.
Mathematical function library provided as loadable extension.	See The Math class.
Call database stored procedures with output parameters with the new `IN`/`OUT` keywords.	See EXECUTE (SQL statement), Stored procedures.
C extension support has been extended with Informix-like C API functions.	See C API functions.
The runtime system now shares several static elements among all processes, reducing the memory usage. The shared elements are: Data type definitions, string constants and debug information. For example, when a program defines a string containing a long SQL statement, all fglrun processes will share the same string, which is allocated only once.	See Runtime system basics.
The `IMPORT` instruction allows to declare a C extension module.	See IMPORT C-Extension.
The `WIDTH` and `HEIGHT` attributes can be used for `IMAGE` form items, as a replacement for `PIXELWIDTH`/`PIXELHEIGHT`.	See HEIGHT attribute, WIDTH attribute.
New debugger commands (`call`, `ignore`).	See Debugger commands.
Presentation styles support now pseudo selectors such as `focus`, `active`, `inactive`, `input`, `display` for fields and `odd` / `even` states for table rows.	See Pseudo selectors.
New presentation style attributes were added: `'errorMessagePosition`' can be used for windows to define how the ERROR message must be displayed; `'highlightTextColor`' for tables allows you to change the color of the selected line; `'border`' allows you to remove the border of some widgets like button, images; `'firstDayOfWeek`' can be used for DateEdit widget to specify the first day of the week in the calendar; The auto-selection behavior for ComboBoxes and RadioGroup can be changed using '`autoSelectionStart'`.	See Style attributes reference.
Primary key, foreign key and check constraints can be specified in static SQL CREATE TABLE statements: CREATE TABLE t1 ( col1 INTEGER PRIMARY KEY, col2 CHAR(2), col3 DATE, FOREIGN KEY (col2) REFERENCES t2(col1) )	See CREATE TABLE.
With X11 or Windows™ TSE environments, you can now automatically start up the front-end with FGLPROFILE entries.	See Automatic front end startup.
The `base.Channel` class now has an `isEof()` method to detect end of file.	See Read and write simple lines.
Ignoring the CTRL_LOGOFF_EVENT events on Microsoft™ Windows platforms.	See Responding to CTRL_LOGOFF_EVENT.
Up to fourth accelerators can now be defined for an action in actions defaults files or in the `ACTION DEFAULTS` section of form files.	See Defining keyboard accelerators.
Specify TTY attributes (`COLOR`, `REVERSE`) and conditional TTY attributes (`COLOR WHERE`) for all type of fields.	See COLOR attribute, REVERSE attribute, COLOR WHERE Attribute.
New built-in function to set an environment variable: `FGL_SETENV()`.	See FGL_SETENV().
The XML reader and writer classes have been extended to properly support markup language entities (like HTML's ` ` ).	See The XmlReader class, The XmlWriter class.
The fgldbsch tool can now extract database tables with LVARCHAR columns. The LVARCHAR type is converted to VARCHAR2(n>255) in the .sch file.	See Data type conversion control.

Table 2. What's new in Genero Web Services (GWS), Version 2.00
Overview	Reference
You can now choose to use Document Style Service (Doc/Literal) or RPC Literal Style Service (RPC/Literal) with Genero Web Services (GWS), for .NET compatibility and WS-I compatibility (standards defined by the Web Services Interoperability organization). Document Style Service allows you to exchange complex data structures, such as database tables or word processing documents (MS.Net default) RPC Literal Style Service is usually used to execute a function, such as a service that returns a stock option Note: RPC/Encoded Style Service (Traditional SOAP section 5) is available for backwards compatibility.	See Choosing a web services style and Writing a Web server application.
Genero Web Services now provides a tool, fglwsdl, to allow a Genero application that is accessing a Web Service to obtain the WSDL information for the service. It does not matter what language the Web Service is written in. The fglwsdl tool is installed in Genero as part of the Genero Web Services package.	See fglwsdl.
You no longer need to create a runner that includes the Genero Web Services package. Instead, your applications import the Genero Web Services library named `com`. This library provides classes and methods that allow you to perform tasks associated with creating GWS Servers and Clients, and managing the Web Services.	See The com package.
GWS now supports SOAP header management through the `CreateHeader` method in the Web Service class that is part of the Web Services library (`com`).	See The WebService class.
HTTPS support has been added on the client side. GWS supports secure communications through the use of encryption and standard X.509 certificates. Based on the OpenSSL engine, new security features allow a Web Services client to communicate with any secured server over HTTP or HTTPS. A new tool is provided, fglpass, allowing you to encrypt a password from a standard X.509 certificate, and to decrypt a password you previously encrypted with a certificate. Entries in the `FGLPROFILE` file are used to define the configuration for client security.	See fglpass, Encryption, base64 and password agent with fglpass tool, and The FGLPROFILE file.
You can configure a GWS Client to connect via an HTTP proxy by adding an entry in the `FGLPROFILE` file.	See Configure a client to connect via an HTTP Proxy.
You can define multiple Web Services in a single Genero DVM. When you start the Web Services engine, all registered Web Services are started.	See The WebServiceEngine class.
You can remap the location of Genero Web Services using entries in the `FGLPROFILE` file, depending on the network configuration and the access rights management of the deployment site.	See Using logical names for service locations.
Serializing Genero data types: you can add optional attributes to the definition of data types. You can use these attributes to map the BDL data types in a Genero Web Services Client or Server application to their corresponding XML data types.	See Attributes to customize XML serialization.
The WSHelper.42m library file contains internal 4GL functions to handle SOAP requests and errors. The file is provided in the $FGLDIR/lib directory of the Genero Web Services package, and should be linked into every Genero Web Services Server or Client program.	See Compiling the client application and Compiling GWS server applications.
