Overview

• What is .NET?
• How do I get started?
• What about .NET and GeoMedia?
• Example Applications
• Q A

3
What is .NET?

• It is huge, It is software
• Provides an software environment to develop and
  execute modern applications
• Like E-Business, Grid Computing, Web Services,
  Utilility computing, Autonomic computing,

4
What is .NET?

• Competitive products include J2EE and IBM
  Websphere
• IBM has defined e-business on demand as an
  enterprise whose business processes -- integrated
  end-to-end across the company and with key
  partners, suppliers, and customers -- can respond
  with speed to any customer demand, market
  opportunity, or external threat.

5
What is .NET?

• This new software model integrates horizontally
  to link data, legacy systems, and custom
  applications, and this integration requires new
  levels of data integrity and transaction
  processing

6
What is .Net?

• It allows an enterprise to connect with other
  enterprises, other business processes, other
  applications, and billions of pervasive computing
  devices
• Open specifications and industry standards are
  the only realistic way that all of this can
  connect

7
What is .Net?

• Grid computing allows distributed computing
  resources to be shared and managed as if they
  were one, large, virtual computer like water,
  electricity, gas
• Think of the water supply its completely
  virtualized. Our interface is a water spigot!
• See Scientific American, March 2003

8
What is .Net?

• Autonomic computing
• Autonomic systems will self-manage, self-protect,
  balance workloads, install device drivers, and
  upgrade software
• See Scientific American, June 2003

9
What is .Net?

• Microsoft .NET comprises most of these concepts,
  and is built upon
• The .NET Framework
• Microsoft Visual Studio .NET
• Servers like Microsoft Windows Server 2003,
  Microsoft SQL Server, and Microsoft BizTalk
  Server

10
What is .NET

• Client software, such as Windows XP, Windows CE,
  and Microsoft Office XP
• The .NET Framework is an integral Windows
  component for building and running the next
  generation of software applications and Web
  services

11
.NET Framework
WindowsForms
XML Web Services
Web Forms
ASP.Net
Data and XML Classes
Base Framework Classes
Common Language Runtime
12
The .NET Framework

• 20 different programming languages
• Plumbing for developing software built in,
  enabling developers to focus on the core business
  logic code
• Easier to build, deploy, and administer secure,
  robust, high performance applications

13
The .NET Framework

• Common Language Runtime or CLR is the core of
  .NET
• Like an operating system running on another
  operating system
• Like Java Virtual Machine, or the VB runtime
• Abstracts the operating system even more
• Windows itself is to close to the hardware
• Is portable in theory (BSD Unix)

15
CLR

• The CLR is different
• A .NET compiler generates binary executable
  software in a p-code format called Common
  Intermediate Language or CIL
• At runtime the CLR re-compiles or JIT-compiles
  (Just In Time) the CIL into native code such as
  x86 machine language. 

16
CLR

• Managed code runs in the native machine
  language of the system on which it is launched
• The first invocation of an assembly is cached in
  its native machine code for subsequent
  invocations

17
Framework Class Library FCL

• Framework Class Library or FCL
• The FCL contains hundreds of classes
• Classes pervade every aspect of .NET

18
Framework Class Library FCL

• Framework Class Library reflects .NETs
  object-oriented nature.
• Most objects are extensible through class
  inheritance and other interesting .NET techniques
• The FCL is one of the most extensive class
  libraries

20
FCL - Base Classes

• Base classes provide standard functionality
• Input/output, string manipulation, security
  management, network
• Communications, thread management, text
  management
• User interface design features.

Data and XML Classes

22
FCL - Data and XML Classes

• ADO.NET classes enable developers to interact
  with data accessed in the form of XML through the
  OLE DB, ODBC, Oracle, and SQL Server interfaces
• XML classes enable XML manipulation, searching,
  and translations

24
FCL - ASP.NET classes

• The ASP.NET classes support the development of
  Web-based applications and Web services.
• Web Forms are analogous to Windows Forms and the
  design time and execution environments look and
  feel very much the same

25
FCL Windows Forms

• The Windows Forms classes support the development
  of desktop-based smart client applications

26
.NET Framework

• Class libraries provide a common, consistent
  development interface across all languages
  supported by the .NET Framework
• CLR and the .NET Frameworks allow the seamless
  reuse of code written in any supported language
• But also allows the components to be extended in
  another language

27
.NET Framework

• The .NET Framework is freely downloadable
• http//msdn.microsoft.com/netframework/downloads/d
  efault.aspxs
• Its about 23 MB
• Once installed, you can run any .NET application

28
Building .NET Applications

• The .NET Frameworks contains a collection of
  tools and compilers to generate .NET applications
• MicroSoft provides C, VB.NET, C, and J
• There are at least 20 other compilers from other
  sources.
• You can generate .NET apps with just the
  Framework.

29
Visual Studio .NET

• However, to be productive, most developers use
  Visual Studio .NET
• Comprises a single Integrated Development
  Environment for the Framework Classes and all
  .NET languages
• Many, many tools to develop apps
• Application delivery packaging

30
How do get started?

• Develop on Windows 2000 or Server, Windows XP
  Professional or Server
• Target these same platforms
• Make sure Internet Information Services are
  installed and functioning
• Buy and install Visual Studio .Net
• Install your GeoMedia products

31
How do get started?

• VB6 and C 6 will run just fine as well at the
  same time
• Utilize the many free or cheap MS local technical
  sessions
• Consult the many technical manuals available at
  your local book store
• Utilize the Microsoft .NET online areas, and
  other services like CodeProject
• MSDN Magazine

32
What language to use

• Probably currently easier to use VB.Net than C
  for GeoMedia apps
• More enterprise type apps and examples seem to be
  biased towards C. MSDN magazine seems to be
  more C oriented
• Most of the Framework and Visual Studio .NET
  written in C
• C apps are a little faster

33
What language to use

• If you are a C or C developer, C for sure
• If youve always wanted to learn C, use C. In
  many ways, C is a leaner easier C
• You can still write standard MFC and ATL C
  applications.

34
What about .NET and GeoMedia?

• Version 4 and 5 GeoMedia seem to work pretty well
  with .NET
• Version 4 GeoMediaWebMap will not
• Not all objects seem to work with .NET
• Customer requirements will probably dictate the
  time when all objects will work well with .NET

35
What about .NET and GeoMedia?

• In the mean time, I would recommend getting
  started on small scale apps
• Also applications, particularly Web Apps, in the
  portions were GeoMedia is not utilized
• A major focus in .NET is Internet oriented
  applications and WebServices

36
What about .NET and GeoMedia?

• COM versus .NET
• COM will not disappear, but .NET Framework is a
  bigger, better, faster COM
• But .NET provides many tools/classes for working
  with legacy COM object hierarchies like GeoMedia
• What is Intergraphs direction?

37
City View Example

• .Net truly is a Rapid Develop Environment
• CityView is a perfect example of the power of
  .NET to utilize Web Services to create
  interesting applications.
• Code

38
Web Services City View
39
GeoMedia Example

• A Water Company wants to maintain an atlas sheet
  approach for the maintenance crews
• Various interface mechanisms and plotting
  mechanisms are based on a standard tiling scheme
  ( 3000 X 2000 )
• Sheets are being added somewhat frequently.

40
GeoMedia Example

• Need a tool to generate all the
  interface/generation mechanisms from single

41
ASP.Net Example

• Our Web applications tend to have many interface
  mechanisms for map navigation
• ASP.NET provides a rich environment for extending
  existing controls
• And debugging ASP really works!
