Visual Studio 2005 Team Edition for Database Professional

 

Reason behind Microsoft provided this plugin:

Usually in any project developers or db guys will work on sample data.

On when it comes to production db all the woes comes into picture.

And it is tedious at that point to change the sps and tables ,columns ,datatypes and the null values.

 

So db changes should be tracked like code in VSS (here it is VS Team Suite) using Team Foundation Server.

Creating tables and generating with some sample valid data. ( u can put some regular expression on the data, max and min values ,etc etc conditions)

All the views ,triggers ,etc etc can be done here.

It will help in Database refactoring

We can unit test cases also.

After doing all the changes we can checkin the code.

All the object (tables,triggers, etc) will be generated as sql files

Finally DB person will review and run that sql file in production server.

It will help in Build/Deploy

 

Summary:

Integrate db professional job into vss and tracking his changes to improve overall performance.

This is a plugin in visual studio.Afer installing this you will get 4 templates in vs devenv

  Sqlserver 2000,Sqlserver 2000 wizard, Sqlserver 2005,Sqlserver 2005 wizard

Finally the output is a sql file which contains the script.

 Note: It wont do any changes in the developer code.

Second Topic:

Creating Simple Custom Activities in WF

 

Every application contains some sort of workflow.Earlier we are writing our custom logic to handle long running applications.Now Microsoft found this gap and came up with Workflows.

 

First point to understand workflows work in Asynchronous manner.

And it is nonpremptive (ie nobody can interrupt. When it completes then only others can take control).

 

Y we want custom activities?

If we want domain specific like graph like workflows (In WWF they provided sequential and State machine).

 

WF follows episodic execution means they are long standing processes.Thats why we cant block the other resources.We have to persist the state in a persisting store ( it may be db,filesystem or ur custom one)

 

The entire transaction will be performed in one thread.

There is no multithreading here.

 

 

Life Cycle:

                                       Method used

Initialize                             CreateWorkflow

Execute                              Start

Uninitialize

 

In Initialize state if you overrrided createworkflow method for a custom activity then it is called synchronously..

 

We can create  a.Custom properties

                           1.Dependent  (getting value for an activity from property of another activity)

                           2. Independent

            b. Custom Events

            c. Custom Methods

 

Use queueing services to understand the asynchronous behavior better.

 

Cancel State: It can done by parent activity and at that time child activity should be in execution state

Faulting state: Exception handling( unhandled errors) should be performed here.

 

Compensatable Activity:

When we have to think about compensation in workflows?

Parent is success in its work but down the line its subsequent child activities may fail.Then think for compensation.

Compensate method is there and it will be for only successful closed activities.

 

How to configure the UI of workflows?

We can customize the UI of workflow as per our requirements.

We can add an image etc etc.

Extend Activity Component Model

Note: Write separate classes for extending designer, validation, serialization, code generator (use codedom), toolbox items.

 

Summary:

 

First understand the workflow life cycle (they differ logically from asp.net life cycle)  

U can customize the look & feel of workflow UIs through Activity Component Model

 

We can expect creating composite activity in the next session.

RoadMap: Microsoft will extend this workflow into biztalk.

Now if u want internet based applications go for biztalk and if it is intranet then WWF.

 

Preffered book is Essential Workflow foundation by Dharma Sukla. This is meant for advanced  concepts in workflows.People should have basic knowledge in the WWF.

If a girl (lady) posts any query in any of the forums then the response will be given spontaneously and it will be a massive response.Even nonactive members also responds.

It wont happen when a boy(gent) posts a query.

Why is it so?

Dont trust ladies that much...

 

If we include Unit tests in our code and you dont want them anyway in production environment (means release ) then use conditional attributes

 

Unit tests makes assemblies larger and we dont them in production.

 

Simplest way provided in vs is this.

 

We define conditional attributes in debug (Project properties -> debug) and we wont define in release mode (select the same dropdown).

In my experience in this field I found some tough and intelligent guys in the management.

 

But still they will show favour (weekness) in case of ladies.

India won the world cup yesterday in T20 Cricket World Cup.

What a marvellous victory!!!
Even my neighbour (she is at age 55) watched the cricket match for the first time in his life.

She also enjoyed very much.May be she will become one of the big fan of Indian Cricket Team.

Tendulkar commented that we always considered seniors and juniors in the team.

But I think they should be some change in the Indian team.We are giving more importance to Seniors.

Just make a young team.

But its a lesson to the Indian Team as they exited from the World Cup( in early 2007) in the first round itself.

At that time lot of expectations are there.

Now with no expectations they went and got the cup.

They have to play at any place at any moment to their expectations.

 

For the first time in Bangalore after 1.8 yrs I found no traffic even at the peak time ie 8:30 PM

All roads are traffic free.

No vehicles and all shops are closed .

Crackers burned.

 

 

My sister has donated her 6 months salary for AnnaPrasadam scheme in Tirupati Venkateswara temple on 8th Sep 2007(Saturday).

 

We went to Tirupati on Friday and reach Tirupati on Saturday.

 

She donated 1 lakh for a scheme (serving the devotees with food) who visit Tirupati temple.

 

It will actually serve the poor people also.

 

May be that one lakh is very precious for my family at this moment.

 

But by seeing the poor and my sister (younger) beliefs we finally decided to donate money.

 

I like my sister very much becoz of this kind behaviour towards poor.

 

God please do all the favours for this world including my sister too.

From the last one and  half year I am suffering from severe headache.

Met so many doctors and taken so many medicines.

One doctor told me to take brain scan.Told me high bp.

Finally I was vexed with English medicines.

Went to Homeopathy doctor in Jayanagar.

Now I am cured.

Doctor told me to stop using medicines.

I felt very happy.

I am thankful to my team and the cab driver Jalal for supporting me in recovering my health.

Singularity is a research project in Microsoft Research that started with the question: what

would a software platform look like if it was designed from scratch with the primary goal of

answer this question by building on advances in programming languages and programming tools

to develop and build a new system architecture and operating system (named Singularity), with

the aim of producing a more robust and dependable software platform. Although dependability is

 

Singularity is a new operating system being developed as a basis for more dependable

system and application software [28]. Singularity exploits advances in programming languages

and tools to create an environment in which software is more likely to be built correctly, program

behavior is easier to verify, and run-time failures can be contained. 

Obfuscators

Obfuscators work by transforming a .NET assembly into an equivalent .NET assembly that is more difficult to understand when disassembled or decompiled. Some obfuscators use ILDASM to disassmble the assembly and operate on the disassembled MSIL, and then use ILASM to reassemble the result. Others operate directly on the assembly without any ILDASM/ILASM round trip. Obfuscators apply a variety of different techniques to make the disassembled source code more difficult to understand. Obfuscation in Visual Studio .NET

http://www.howtoselectguides.com/dotnet/obfuscators/#section-sub-cats

If your obfuscation needs are minimal, and you're a Visual Studio .NET user you may not need to purchase a product at all. That's because Visual Studio .NET includes a copy of the Community Edition of Dotfuscator for .NET, an obfuscator from PreEmptive Solutions. This obfuscator is targeted at students and freeware authors, and supports basic entity renaming and removal of unused metadata, but no advanced obfuscation features. You'll find a review of the Professional Edition of Dotfuscator later in this Guide, and PreEmptive has a comparison chart online showing what's in their various editions.
