Update Config file settings Automatically using Windows Application

Hi Friends,
Sometimes we need to search for the application or the code snippet which
will work as per our requirements- Like update the configuration file 
automatically. Because this is the tedious task to update the config file
 manually and we want there should be a simple application where I can 
enter the server name, database name, user id and password and click on 
update should update our configuration file automatically.
So now nothing to worry and this article is all about that. This article will 
describe mainly about the updation of Configuration file 
(App.Config or Web.Config) settings by using the Windows Application. 
This windows application will take the inputs from the user like Database
 server name, user name, password etc and will update the configuration 
file settings automatically without opening the config file.
This article will describe each and every steps of creating the windows 
application and then code snippet so that we can use as is or can also 
modify as per our requirements.

18 most common validation scripts to validate the Controls in ASP.Net

Hai Friends,

Many times, we search in the Google to get the correct validations expression to validate our textboxes. And its true that we get various links where others have given their own validations expressions and controls using some scripts, regular expressions etc.

Then we implement those expressions and at the end, we found that it’s not working and again we start our search for the next link. It becomes very complicated whenever we have to fix the validation issue in a very small time and then we didn’t get the correct expression.

So dear folks, now nothing to worry as I have created a CommonScript.js file which contains the validation expression and they all are tested and in my project.

Like you, I also did the same and finally got this file which contains all the general use validation expressions to validate our controls. This CommonScript.js file can be modified as per your requirements like changing the message, modifying the scripts etc.

You can go through the below link for the detailed description:

How to write the connection string and place it on to web.config file

Hai Friends,

Today I was thinking that many times, we are having doubt in writing the connection string in the web.config file. Whether the connection string is correct or not? Is it case sensitive? Is the User Id or userid is correct? Can we write pwd in place of password or Password?

As we can't check it in compile time, so all the error we get at the run time and then we try to replace the attributes of confile file by making the cap-locks to small or vice versa.

So I though to write an article which will be useful for we all who are working in Microsoft Technologies with the database.

As it will help to create all type of connection strings for their respective providers, so we need not to worry that it is applicable only to SQL Server.

You can go through the below link for the details with the screenshots where i have explained that how you can create and test your connection string before putting in the configuration file.

Hope it will help to all the members...

Creating Code Snippet with the Shortcut in Visual Studio 2010

Hai friends,

Today i was thinking that lot many times we gets fed-up with writing lot of duplicate code so can't we create such type of shortcut so that no need to write the whole code and we can do it with a small shortcut. Then I created a Code snippet for the header of the files which will write the below stuff for me by just writing a small shortcut FHC and there are few place holders which we need to write it and its done:

/==================================================
//                       CTSInvoiceBO.cs
//
//       This file is the code for Business Objects of CTS invoice.
//------------------------------------------------------------------------
//
//               Modification Control Log
//
// Date           By  Version  Description
// 03/18/2012  PA  1.0       Business Objects of CTS invoice
//
//
//==================================================

Then i created a snippet file and added to my visual studio IDE and now i don't need to write all this code manually. There are few place holders which we need to update and rest all code and other format will be done automatically.

Guys you can follow the below link where you can get the detailed description of how we can create this Code snippet and how can we attach it with our Visual Studio IDE and also how to create the shortcut's for it.

Visual Studio Light Switch

Hai Friends,

This post will talk about the latest version of visual studio named as "Light Switch". 

This resource will describe about the new development tool which is the extension of Visual Studio 2011 with lot of features as inbuilt so that the developer only need to think about the application business logic rather than thinking about the whole application architecture and design.

The Light switch application contains many default functionality which are required for every business applications like 

• Search capabilities: – the business application will have the search feature to search the contents inside the business applications.
• Sort capabilities: - The business application will also have the sorting and rearranging capabilities in the grid where the data is displayed
• Export: – this is also a generic requirement where the export feature is also built-in. Means all the business application created by using LightSwitch will have default export functionality of the data.
• Addition to all the above features, the LightSwitch application will also have the default features to add, update, save and delete features. 
• The data validation logic is also built-in in the LightSwitch business applications. It means the data which is inserted/updated or deleted can be controlled by using the validations. 
• Extended features: - With the above all features, there are few extended features like appearance of the application, we can use custom controls. Also we can format the UI by writing the custom business types.

3 small things in C# code

1. Null Coalescing Operator (??)

A new operator can be used which can be shortcut of ternary operator to check the null value:

Ternary operator (?:):
string empName = (value != null) ? value : string.Empty;
we can write it using null-coalescing operator (??):
string empName = value ?? string.Empty;

2. The As Cast
we might have seen the code something like:
if (customer is DeluxCustomer)
{
var dCust = (DeluxCustomer)customer
// ...
}
This is redundant because we are checking the type twice. Once in the is check and once in the cast.
We can use as operator in place. This will cast the type if the types are compatible, or return null if not:
var dCust = customer as DeluxCustomer;
// ... we can write if condition to check for null
}
we can avoid double-checking the type.
3. Auto-Properties
This is the new concept to define the properties in C#: we can define the auto-property without much code:
public class Employee
{
public int ID { get; set; }
public string name { get; set; }
}
