 
Fortran
for .NET Language System
|
|
Fortran for .NET allows you to create applications for the
Microsoft .NET Framework. Lahey and Fujitsu have combined advanced
compiler technology with support for Forms designers and Web
Services to enable Fortran organizations to develop .NET
applications with Fortran as easily as with other Microsoft .NET
languages. Fortran for .NET consists of a Fortran compiler and
associated tools designed to help you create applications that run
in the .NET Framework.
The Fortran for .NET language system is included in LF Fortran
v7.0 Enterprise, Developer, and Educational editions.
Fortran for .NET compiler
Th Fortran
for .NET compiler targets Microsoft's .NET Framework. The compiler
does not directly generate processor dependent object code; rather,
it generates Microsoft Intermediate Language (MSIL) code assemblies
and code modules. The code in an assembly can be executed on any
computer that supports an execution engine called the Common
Language Runtime (CLR), such as the .NET Framework.
The CLR does much more than provide the ability to operate on
different operating systems, it also provides the basis for
interoperability between different .NET languages, interlanguage
debugging, versioning, and application deployment, among other
things.
Applications that are targeted for the CLR are called managed
applications, or managed code. Managed applications are required to
be type safe and to present standardized interfaces, so that
interoperability and security requirements can be met. Because some
older Fortran features (such as COMMON and EQUIVALENCE) can violate
the CLRs rules for type safety and interfaces, certain restrictions
had to be placed on .NET applications that do not allow 100%
compatibility with Fortran standards. For details on restrictions,
see Restrictions
on Fortran for .NET Code.

Visual Studio .NET integration
Visual
Studio .NET 2003 is the industry standard in development
environments. Fortran for .NET Visual Studio integration includes
project management facilities, project/code templates, on-line
integrated help, Fortran-smart editing, and mixed-language
debugging.
Project Management
To efficiently manage the items that
are required by your development effort, such as references, data
connections, folders, and files, Visual Studio .NET provides two
containers: solutions and projects. An interface for viewing and
managing these containers and their associated items, Solution
Explorer, is provided as part of the integrated development
environment (IDE).
Project/Code Templates
Project/code templates
syntactically correct compilable source code shells and associated
project setting that help you create applications or services.
Fortran for .NET provides the following Visual Studio project types:
- The Empty Project template provides a solution and
project without any source files or references. You can add items
to this project by using the "Project/Add New Item" menu
selection.
- The Class Library template consists of a library
project and a skeletal Fortran class library containing a single
static method. When compiled, this project type creates a .NET DLL
file, which may be supplied as a reference to other .NET
applications.
- The Console Application consists of a console project,
and a skeletal main program. When compiled, this project type
creates a console application. If this application is invoked from
a console, it executes within the console. If the application is
invoked from an icon, the Run menu, or Windows Explorer, it
creates a console to run in, and destroys the console when the
program completes execution.
- The ASP Web Application template is a Web Forms
Designer project, which begins in design mode with a blank Web
form. Controls may be dragged from the toolbox onto the form, and
Fortran source code will be generated to implement the control.
The project consists of an HTML web page that uses Fortran for
.NET to provide the code behind.
- The ASP Web Service template is also a Web Forms
Designer project in which the Web Form provides a user interface
on the local machine, with Fortran for .NET powering the
application on the server side.
- The Windows Application template is a Windows Form
designer project, which begins in design mode with a blank form.
Controls may be dragged from the toolbox onto the form, and
Fortran source code will be generated to implement the control.
This project type compiles into an event driven Windows
application.
- The Setup and Deployment template allows the programmer
to create installation programs that can ease the task of
distributing .NET applications. A setup project packages the files
that make up an application, facilitates the creation of directory
structures, and provides a means of installing and registering
assemblies.
- The Database template provides a means of manipulating
databases and designing and executing SQL scripts and queries
without having to create an application.
On-line
Integrated Help
The on-line integrated help provides Fortran
for .NET installation and getting started instructions, a Fortran
for .NET Users Guide, and a Fortran for .NET language reference. It
also includes the MSDN Library and Visual Studio SDK help.
Fortran-Smart Editing
The Fortran for .NET language
system provides the Visual Studio editor with the smarts to
recognize and color-code Fortran language syntax.
Mixed-Language Debugging
Fortran for .NET code can be
debugged in the Visual Studio debugger. If your application includes
procedures written with other .NET languages, the Visual Studio
debugger can seamless step from Fortran for .NET code to the other
language code and back again.
Windows Forms
Windows Forms is the new
platform for Microsoft Windows application development, based on the
.NET Framework. This framework provides a clear, object-oriented,
extensible set of classes that enables you to develop rich Windows
applications.
A form is a bit of screen real estate, usually rectangular, that
you can use to present information to the user and to accept input
from the user. Forms can be standard windows, multiple document
interface (MDI) windows, dialog boxes, or display surfaces for
graphical routines. The easiest way to define the user interface for
a form is to place controls on its surface.
Within a Windows Forms project, the form is the primary vehicle
for user interaction. By combining different sets of controls and
writing code, you can elicit information from the user and respond
to it, work with existing stores of data, and query and write back
to the file system on the user's local computer.
Although the form can be created entirely within the editor, it
is easier to use the Windows Forms Designer to create and modify
forms. Fortran for .NET's support for the Windows Forms Designer
makes it easy for you to create Windows applications with Fortran.
ASP.NET Web Forms
Web Forms are an
ASP.NET technology that you use to create programmable Web pages.
Web Forms render themselves as browser-compatible HTML and script,
which allows any browser on any platform to view the pages. Using
Web Forms, you create Web pages by dragging and dropping controls
onto the designer and then adding code, similar to the way that you
create Windows Applications with the Windows Forms Designer.
ADO.NET
ADO.NET provides consistent
access to data sources such as Microsoft SQL Server, as well as data
sources exposed through OLE DB and XML. Data-sharing applications
can use ADO.NET to connect to these data sources and retrieve,
manipulate, and update data.
ADO.NET cleanly factors data access from data manipulation into
discrete components that can be used separately or in tandem.
ADO.NET includes .NET Framework data providers for connecting to a
database, executing commands, and retrieving results. Those results
are either processed directly, or placed in an ADO.NET DataSet
object in order to be exposed to the user in an ad-hoc manner,
combined with data from multiple sources, or remoted between tiers.
The ADO.NET DataSet object can also be used independently of a .NET
Framework data provider to manage data local to the application or
sourced from XML.

What can you do with Fortran for .NET and why would
you want to?
|
What? |
Why? |
|
Mix Fortran and other .NET languages in the same
application. |
Libraries written in other languages exist. Use the right
language for the right task. |
|
Create Windows user interfaces by dragging and dropping
buttons, data entry fields, check boxes, and
more. |
Reduce development costs. You want more than a command-line
interface. |
|
Create web forms using the same technique. |
You want to make your application and its professional user
interface available to the world over the
Internet. |
|
Create reusable custom controls, with Fortran, that anyone
can use in their Visual Studio environment. |
You know Fortran, you've created custom controls for one
application, why not reuse those controls? Reduce development
costs. |
|
Create procedures that access or collect data that exist
somewhere over the Internet. (XML Web service.) |
Somebody else already did the work of collecting the
information. Make it available, accessible. Offer a
service. |
|
Create applications that call procedures that access or
collect that data. |
Use the data that's available. You can reduce the time to
obtain answers. |
|
Create COM objects with Fortran. |
You know Fortran. Use your Fortran procedures from other,
non- .NET language programs. |
|
Call, from Fortran, COM objects written in other
languages. |
You have access to any COM object that's ever been
written. |
|
Create applications that run wherever .NET has been
implemented. |
Microsoft's .NET Framework is based on open standards and
will be implemented on other platforms. |
|
Create libraries of useful functionality with Fortran
(i.e., class libraries) that can be used and extended by any
.NET language. |
Don't limit your users to only those who know
Fortran. |
|
Easily call Windows APIs from Fortran. |
You know Fortran and want to use the building blocks of
Windows. |
|
Code functionality into your web pages using
Fortran. |
You know Fortran. It's a way to add smarts to a web
page. |
|
Easily read from and write to databases. (ADO.NET - drag
and drop database access.) |
It's where you keep your data.
