.Net Training Updates

When I am working with MVC project I had a requirement like to clear all the errors and text entered inside a bootstrap modal. So that when I opened the modal again I could see a plain binding.

        $("#guest_form input[type='text'],input[type='password']").val('');  
        $("#guest_form input[type='text'],input[type='password']").each(function () {  
            $(this).removeClass('form-control input-validation-error');  
            $(this).addClass("form-control");  
        });  
        $(".field-validation-error").text('');  
    }); 

Initially my modal looks as follows

On submitting the modal without entering any data here my modal looks as follows

On closing the modal and opening it again I am still seeing the errors on my modal

What I need is I would like to clear all the validations and the classes which got applied using MVC validations so that it should again show me the original screen as follows

ExecuteNonQuery

ExecuteNonQuery method will return number of rows effected with INSERT, DELETE or UPDATE operations. This ExecuteNonQuery method will be used only for insert, update and delete, Create, and SET statements. 

ExecuteReader

Execute Reader will be used to return the set of rows, on execution of SQL Query or Stored procedure using command object. This one is forward only retrieval of records and it is used to read the table values from first to last. MOSTLY HELPFUL WHEN SEARCHNG FOR EXISTANCE OF PARTICULAR DATABASE RECORDS.since its only for searching and retrieval of records here as well INSERT, DELETE or UPDATE queries for its operations tobe performed is not applicable.

Execute Scalar

Execute Scalar will return single row single column value i.e. single value, on execution of SQL Query or Stored procedure using command object. It’s very fast to retrieve single values from database. as comapred to executeNonquery its not depended on INSERT, DELETE or UPDATE queries for its operations tobe performed.

What to choose between WCF or WEB API..?

1. Choose WCF when you want to create a service that should support special scenarios such as one way messaging, message queues, duplex communication etc. while we need to choose web API. When you want to create a resource-oriented service over HTTP that can use the full features of HTTP (like URIs, request/response headers, caching, versioning, various content formats)

2. Choose WCF whenever you want to create a service that can use fast transport channels when available, such as TCP, Named Pipes, or maybe even UDP (in WCF 4.5), and you also want to support HTTP when all other transport channels are unavailable. While we need to choose Web API when you want to expose your service to a broad range of clients including browsers,  iPhone, mobiles and tablets.

Hello Kirit,

The application which were devloped about 2 decades back was mostly coded in java and so you will see so many of the application (in several company and outside) written in java. .Net(collectively C#) on the other hand is a new entrant in the ring and there have been several devlopment on that too..

A good programmer needs strong logics, algorithm building and problem solving ability. The languages (java or anything else) gives you the syntax to code what you have thought. Of course each programming langauge has its own pro n cons (depends on what you are looking in the language). As mentioned above there are great frameworks designed in java. Java might give you an edge but a career is what you make out of it.

Cheers!

Thanks,

Control to validate an error message. Are common feature in all the controls.

Various validators are requiredfeild validator ,compare validator ,regular expression validator,custom validator,range validator  and validation summary.

1. Required field validator asks for the missing field in server side controls like textboxes dropdowlistot list box or checkboxlist and tells to populate in the form of error message.

2. Compare validator asks for two textboxes or familiar controls to have the exact match of the data types ore expressions.

3. Regular expression validator asks for correct format of email passwords and phone numbers or website address.

4. The custom validator does the same what regular expression validator does additionally it can customize its own features of validation by language coding means.

5.Validation summary. Display list of error messages in the form of bullet list on the top of the registration page etc.

6. Range validator checks whether the data types entered is falling in the correct ranges. Example values between two integer or dates or strings or float currencies etc..

1. Optimization of performance in receiving messages between client and server.

2. Optimised display features.

Explanation

1. Earlier versions of Asp.net had lack of performance of message transfer between client-server communication as server response time was lagging behind .this problem was rectified by the concept of angular js.  a new version of HTML framework. where WEB API was the server side.

2. HTML display features had optimised level in Angular JS both in terms of fastest and accuracy in message transferring performance and display characteristics in the WEB BROWSERS. WHICH EARLIER VERSIONS OF HTML LACKED.
