Microsoft has everything of its own:
 - development tools: Visual Studio 6.0 (C++, J++, Basic, Interdev)
 - web server - IIS (Internet Information Server)
 - database server (MS SQL Server)
   etc. etc. etc.

msdn.microsoft.com/workshop/default.asp - excellent refs - HTML, JavaScript, etc.)
msdn.microsoft.com/workshop/c-frame.htm#/workshop/author/default.asp - same thing, but only can viewed using Internet Explorer
support.microsoft.com/support/kb/articles/Q234/0/67.ASP - caching in IE and how to turn if off

Microsoft recently produced some really good stuff.  Their Internet Explorer is the best browser on the market. xml/xslt/soap development is very good. Windows 2000 and Office 2000 are good and their use of xml is very exciting.  For example, you can save Excel document as HTML - and it creates an XML file which stores not only data, but also formulas.  You can create similar XML files on a unix server (in Java servlet or Perl CGI script) and serve them from your web server (with xls extension or simply print with proper MIME type).  Browsers will pick them up and pass to Excel-2000, which will open them WITH ALL THE FORMULAS WORKING !!!. Client now has much better way to play with his/her data and to print them in a convinient and flexible ways.

But the most exciting development is ".NET" - see below.

  .NET - in just few words home - top of the page - email

.NET  (pronounced "dot net") is a new Microsoft plan to take over the world by selling services instead of selling software.
.NET is also a response to the popularity of Java platform. The Microsoft's C# language is really similar to Java, although you will notice some minor differences, like using the word "using" instead of "import" :) .

msdn.microsoft.com/net/ - .NET on the Microsot MSDN site
java.oreilly.com/news/soap_0900.html - article comparing .NET with Java Enterprise
www.xmlmag.com/upload/free/features/xml/2000/04fal00/sj0004/sj0004.asp - The Future of COM+ Microsoft's .NET Revealed
www.xmlmag.com/upload/free/features/xml/2000/04fal00/sg0004/sg0004.asp - BizTalk includes a messaging component for integration and an Orchestration engine for modeling - and all the work is done in XLANG, an XML language for describing processes.

Microsoft  .NET's  main strategy is to deliver software as a service (with timeout when license expires).
"Web Services" also help Microsoft products to work better with other platforms by using open Internet standards, such as HTTP and XML.
    (The .NET Framework is entirely built on XML as a communications infrastructure)
Microsoft is funding and encouraging other languages to compile down to the MSIL  (for comparison Sun doesn't encourage compilation from other languages into JVM bytecode - although such tools exist for many languages and scripts - grunge.cs.tu-berlin.de/~tolk/vmlanguages.html)

Here is a close parallelism between Java and C# language:
Sun - Java Microsoft - .NET
Java language C# (C sharp) language 
(and other languages - as long as they
compile into MSIL and run in CLR - see below)
JVM - Java Virtual Machine CLR - Common Language Runtime engine
byte code (JVM instructions) MSIL (Microsoft Intermediate Language)
compile Java into bytecode compile C#, Visual Basic, C++, JScript, etc. 
(other languages such as Perl, COBOL, Python, Smalltalk, etc. are welcome)
into MSIL (thus integrating multiple languages into one system)
Classes written in different languages can inherit from each other and work as part of one application
(distributed objects)
SOAP (Simple Object Access Protocol), XML-RPC
(distributed services)

.NET encourages 3 main types of communication:
    - HTTP w/SOAP formatter
    - TCP channel w/binary formatter
    - SMTP channel w/SOAP formatter

Work with .NET using Perl:

Some buzz-words:
personal subscription servicews
Microsoft Office.NET
Microsoft Visuao Studio.NET
Microsfot bCentral for .NET

.NET Framework - consists of:
  - the CLR (Common Language Runtime engine),
  - the Framework classes

.NET Framework SDK - CD from Microsoft - or a >100 MB download
.NET Compact Framework - for cell phones and enchanced TVs

.NET uses DCOM and SOAP.

CLR issues:
   CLR - Common Language Runtime (engine)
   CTS - Common Type System
   CLS - Common Language Specification
   MSIL - MicroSoft Intermediate Language
   managed code - code for CLR
   managed data - data allocated or garbage collected by CLR

  assembly - unit of files with a manifest (like jar file in Java ??)
  private assemblies
  shared assemblies - for security may use cryptographic keys (provate/public)
  name space
  assembly name

  Application Deployment - simply XCOPY files into a directory. No registration is required !!
  Applicaiton Isolation
  Application domain
  garbage collection
  ValueTypes - like classes, but allocated in stack rather than heap - thus reclaimed automatically on exit of the procedure.
    - HTTP w/SOAP formatter
    - TCP channel w/binary formatter
    - SMTP channel w/SOAP formatter

   Each object has a lease time, and when that time expires, the object is disconnected fro the remoting infrastructure of CLR.

RCW - Runtime Callable Wrapper - to access COM objects from .NET.
CCW - COM Callable Wrapper - to access .NET from COM.

COM, DCOM, COM+ home - top of the page - email

- COM (Component Object Model) started in late 1980s as an attempt to provide active links between applications running on the same desktop. The idea was that you could embed data from one application, say a graph from an Excel spreadsheet, in a PageMaker file. If the data changed in the spreadsheet, the graph would be updated in the Pagemaker file. We take this for granted today, but it was a revolutionary idea in 1989. Originally referred to as the Compound Document Protocol Specification (1989), it was soon renamed into OLE (Object Linking and Embedding). Problems:  link tracking and versioning.
- In 1996 "OLE objects" renamed into"ActiveX objects", to indicate that they were not simply static objects. DCOM (Distributed Component Object Model) was shiped in 1996 - designed to provide a remote procedure call capability on non-Microsoft platforms.

- 1997 - MSMQ (Microsoft Message Queue Server) - for handling asynchronous messaging, and MTS (Microsoft Transaction Server) for synchronous transaction processing - built on top of COM >> COM+ (first shipped as part of Windows 2000).

Windows DNA (Windows Distributed interNetworking Applications architecture) - death of client-server model and advent of truly distributed applications ("servers" have all been renamed  into "services").

Windows DNA 2000 include the .NET Framework and Visual Studio.NET, as well as Microsoft's BizTalk Server 2000, its XML-driven, Internet application integration engine, XML schemas, and tools.

BizTalk Server 2000 is designed to enable businesses to exchange documents based on XML or other EDI (Electronic Data Interchange) standards, with all the necessary routing, tracking, and transformation technologies needed to conduct business reliably. In addition, Microsoft is in the process of retooling all of its 2000-series server products to speak XML natively.

Microsoft is taking the aging COM+ component architecture and radically updating it to make it Web worthy.  XML is at the heart of virtually all of those changes.

DOS home - top of the page - email

In Windows 2000 command prompt window you can:
  - select text :  drag mouse
  - copy text :  right-click (or hit <ENTER>)
  - paste text :  right-click

DOS (Disk Operating System)
Here are some of the links found on google using search for "DOS commands list":
www.easydos.com/dosindex.html - www.csulb.edu/~murdock/dosindex.html

More DOS:

www.bookcase.com/library/software/msdos.util.batch.html - Batch Files
www.pressroom.com/~tglbatch/ - Batch File Applications

To make your life a little bit more convenient while working in DOS window you can use some DOS tips:
To activate autocomplete:
  run regedit 
  find  Command Processor: 
  MyComputer \ HKEY_CURRENT_USER \ Software \ Microsoft \ Command Processor

The CompletionChar should be changed to 9 (TAB) 
(right-click - modify on it)
Creating your own commands (*.bat or *.cmd file scripting):
arguments - %1  %2 ...
use @ to prevent echoing the commands themselves, for example:
@mkdir %2
@copy %1\%3 %2
@echo copied files from %1 to %2
to have ls command I usually make a short file C:\WINNT\ls.bat 
   dir %1 %2 %3 %4 %5 %6 
DOSKEY - very convenient program - adds functionality to your prompt so that you can conveniently edit the command line, recall previous commands and use help.
It is a good idea to have some utilites to zip / unzip the files (and whole directories):
  - zip.exe - unzip.exe
The registry entries for the POSIX subsystem are found under this path: 
   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\SubSystems
And may be set to :   %SystemRoot%\system32\psxss.exe

The Posix entry in this subkey describes the path to the executable file used to start the POSIX subsystem. The POSIX subsystem does not have any parameters or environmental variables that the user can set.
The POSIX subsystem starts whenever a user starts a POSIX application. 
POSIX utilities and their source code are available on the Windows NT Workstation Resource Kit compact disc. 
MKS Toolkit - many convenient tools (unix-like commands, etc)
