I have two tables with a parent child relationship between them

But in the child table I have to allow nulls for the child table as I am using the same table for another scenario.

 

Using LINQ it is not possible to make this situation possible,

 

So I am going to the old way by removing LINQ from my application

Currently I am working on a 3.5 project where I have to do lot of calculations and my methods should be wcf exposed.

 

But I used two dimensional arrays which are not helpful in wcf.. I think they cant deserialize.

I got help from Sendhil to identify this problem . Again  I have to revamp the calculation engine to jagged arrays. Why there is no support for multidimensinal arrays arr[,] in WCF?? Dont know ...

 

I am having a method in service interface

float[,] CalculateProgressPaymentsYearwise(float input_DirectProcurementCost, float []input_OtherEquipmentCosts)

I implemented it also

then in my client application when I am taking service reference ..it is giving error that multidimensional arrays are not supported

you can use a jagged array

file - new project - wcf -> wcf service library

It will create Iservice1.cs and service1.cs files

There is a warning here in Iservice1.cs file

 // NOTE: If you change the interface name "IService1" here, you must also update the reference to

"IService1" in App.config. (if u try to rename iservice1 file then u have to go app.config and u have

to manually do the changes .THats y i added a new service file as per my naming conventions which

automatically updates app.config file.

Please follow.

If u want ur own service file just delete this file and add another
right click on solution ->add new item .. select "wcf service" file and rename (MyWebservice) according

to ur needs.
It will automatically adds two files : IMyWebService.cs and MyWebservice.cs files.

In IMyWebService.cs file
I wrote

"
 [OperationContract]
        int AddTwoNumbers(int firstnumber, int secondnumber);

"

In MyWebService.cs file I added
 public int AddTwoNumbers(int first, int second)
        {
            return first + second;
        }

Thats it.
Press F5 it wil open a window which shows ur added method "AddTwoNumbers"
U can test ur webmethod by giving inputs and u can check the result. Fully flexible in 2008

Then develop a client application
===================================

webapplication:

File -> Add new website -> selcte asp.net website 3.5 c#

right click on project : Add new reference --> system.ServiceModel

right click on project : add service reference.. click on discover and ok

in default.aspx: add using system.servicemodel

and page_load

    ServiceReference1.Service1Client cl = new ServiceReference1.Service1Client();
       Response.Write(cl.AddTwoNumbers(1, 2).ToString());

Make this as startup project ..Press f5.thats it

=======
This procedure is same for windows,console (add code in program.cs file)

In my current project I am migrating an excel application into .net 3.5 project.

my client is using an excel sheet as their project.

After seeing that excel application I learned so much about Excel. we can do so many things in excel.

 1. Dynamic Data Web Site (to use LINQ to SQL)
-------------------------------------------------
 

Refer : http://msdn.microsoft.com/en-us/library/cc488469.aspx

File - new - website - Dynamic Data website template

Location : file system . Language : c#

It will have default.aspx

Open server explorer in vs editor from View tab

connect to a db in sqlserver

Then vs solution explorer .. right click add App_code  folder
Right click App_code folder and add new item and select "LINQ to SQL classes" and name it as northwind.dbml

Drag required tables from server explorer on to northwind.dbml file.

Go to web.config and
check for "  <dynamicData dataContextType="" enableTemplates="false">   "
change enableTemplates = true

Thats it
f5 shows u default.aspx with selected tables.

2. Dynamic Data Entities Web Site (to use the ADO.NET Entity Framework).
===========================================================================
Restful coding : Coding from the url ..

I mean like the below:

Fetch ProductID = 1 : http://localhost:1453/WebSite5/NorthwindDataService.svc/Products(1)

Fetch the Supplier for the Product : http://localhost:1453/WebSite5/NorthwindDataService.svc/Products(1)/Supplier

Fetch Products 11 - 20 : http://localhost:1453/WebSite5/NorthwindDataService.svc/Products?$skip=10&$top=10

File --> New - website -- asp.net website

location: file system  language : c#

Choose an ADO.NET Data Service and click Add (say fielname is WebDataService1.svc ..it will generate webDataService1.cs file too)
Choose an" LINQ to sqlclasses" and click Add (say filename is DataClasses1.dbml)

view tab --> server explorer .. create a connection with db
And drop required tables on DataClasses1 file

Copy the classname of DataClasses1.dbml file ..
And paste in webDataService1.cs  file  at the first line in between <  >

and copy this line "
config.SetResourceContainerAccessRule("*", ResourceContainerRights.AllRead);
"

in InitializeService method

If you could read patiently and understand, its a great knowledge  !

Once there was a little island country. The land of this country was the tiny island itself. The total money in circulation was 2 dollars as there were only two pieces of 1 dollar coins circulating around.

1) There were 3 citizens living on this island country.  A owned the land. B and C each owned 1 dollar.

2) B decided to purchase the land from A for 1 dollar. So, now A and C own 1 dollar each while B owned a piece of land that is worth 1 dollar.

* The net asset of the country now = 3 dollars.

3) Now C thought that since there is only one piece of land in the country, and land is non producible asset, its value must definitely go up. So, he borrowed 1 dollar from A, and together with his own 1 dollar, he bought the land from B for 2 dollars.

*A has a loan to C of 1 dollar, so his net asset is 1 dollar.
* B sold his land and got 2 dollars, so his net asset is 2 dollars.
* C owned the piece of land worth 2 dollars but with his 1 dollar debt to A, his net residual asset is 1 dollar.
* Thus, the net asset of the country = 4 dollars.

4) A saw that the land he once owned has risen in value. He regretted having sold it. Luckily, he has a 1 dollar loan to C. He then borrowed 2 dollars from B and acquired the land back from C for 3 dollars. The payment is by 2 dollars cash (which he borrowed) and cancellation of the 1 dollar loan to C. As a result, A now owned a piece of land that is worth 3 dollars. But since he owed B 2 dollars, his net asset is 1 dollar.

* B loaned 2 dollars to A. So his net asset is 2 dollars.
* C now has the 2 coins. His net asset is also 2 dollars.
* The net asset of the country = 5 dollars. A bubble is building up.

(5) B saw that the value of land kept rising. He also wanted to own the land. So he bought the land from A for 4 dollars. The payment is by borrowing 2 dollars from C, and cancellation of his 2 dollars loan to A.

* As a result, A has got his debt cleared and he got the 2 coins. His net asset is 2 dollars..
* B owned a piece of land that is worth 4 dollars, but since he has a debt of 2 dollars with C, his net Asset is 2 dollars.
* C loaned 2 dollars to B, so his net asset is 2 dollars.

* The net asset of the country = 6 dollars; even though, the country has only one piece of land and 2 Dollars in circulation.

(6) Everybody has made money and everybody felt happy and prosperous.

(7) One day an evil wind blew, and an evil thought came to C's mind. "Hey, what if the land price stop going up, how could B repay my loan. There is only 2 dollars in circulation, and, I think after all the land that B owns is worth at most only 1 dollar, and no more."

(8) A also thought the same way.

(9) Nobody wanted to buy land anymore.

* So, in the end, A owns the 2 dollar coins, his net asset is 2 dollars.
* B owed C 2 dollars and the land he owned which he thought worth 4 dollars is now 1 dollar. So his net asset is only 1 dollar.
* C has a loan of 2 dollars to B. But it is a bad debt. Although his net asset is still 2 dollars, his Heart is palpitating.
* The net asset of the country = 3 dollars again.

(10) So, who has stolen the 3 dollars from the country ? Of course, before the bubble burst B thought his land was worth 4 dollars. Actually, right before the collapse, the net asset of the country was 6 dollars on paper. B's net asset is still 2 dollars, his heart is palpitating.

(11) B had no choice but to declare bankruptcy. C as to relinquish his 2 dollars bad debt to B, but in return he acquired the land which is worth 1 dollar now.

* A owns the 2 coins, his net asset is 2 dollars.
* B is bankrupt, his net asset is 0 dollar. ( he lost everything )
* C got no choice but end up with a land worth only 1 dollar

* The net asset of the country = 3 dollars.

**************End of the story; BUT ***************************

There is however a redistribution of wealth.
A is the winner, B is the loser, C is lucky that he is spared.
A few points worth noting -

(1) When a bubble is building up, the debt of individuals to one another in a country is also building up.
(2) This story of the island is a closed system whereby there is no other country and hence no foreign debt. The worth of the asset can only be calculated using the island's own currency. Hence, there is no net loss.
(3) An over-damped system is assumed when the bubble burst, meaning the land's value did not go down to below 1 dollar.
(4) When the bubble burst, the fellow with cash is the winner. The fellows having the land or extending loan to others are the losers. The asset could shrink or in worst case, they go bankrupt.
(5) If there is another citizen D either holding a dollar or another piece of land but refrains from taking part in the game,  he will neither win nor lose. But he will see the value of his money or land go up and down like a see saw.
(6) When the bubble was in the growing phase, everybody made money.
(7) If you are smart and know that you are living in a growing bubble, it is worthwhile to borrow money (like A ) and take part in the game. But you must know when you should change everything back to cash.
(8) As in the case of land, the above phenomenon applies to stocks as well.
(9) The actual worth of land or stocks depend largely on psychology.

Project Automation:

 

Concerned about your team’s performance? Looking for ways to enhance your team’s productivity and getting rid of all those mundane tasks? Years of consulting and building products have thought me that Automation is the key to improving team’s productivity and bringing joy back to software development.

If your team is seriously looking at automating as much as possible on their projects, you must consider some items like:

• Setting up an automated build for your project. You must explore tools like Ant, NAnt, Maven, GAnt, Rake, etc
• Creating automated unit, acceptance and UI tests for your project. Have a look at xUnit frameworks, FitNesse, Selenium, Watir, Abbot, etc
• Setting up a Continuous Integration (CI) process for your team. Configuring a CI server with Version Control System for your project
• Setting up developer work-stations with all the necessary tools and framework to be able to independently build the project from developer desk in a predictable and repeatable way
• Setting up an evolutionary database design and data migration process using tools like Migrations, Liquibase, etc
• Enabling the automated build to switch between Development, CI, Staging and Live environment using simple properties
• Setting up coding standards for the team and using tools like CheckStyle and other Static analysis tools to automatically validate code format and other aspects with each build
• Adding code coverage or test coverage frameworks like Cobertura, Jester, etc to your build
• Setting up an integrated project dashboard on CI server with various project metrics like BurnUp/BurnDown chart, test coverage trends, test counts, etc. This Dashboard is visible to everyone on the team and all the stakeholders
• Setting up a build promotion process
• Setting up a team wiki which is versioned along with the whole project
