What is JIT (just in time)? how it works?

Before Microsoft intermediate language (MSIL) can be executed, it must be converted by a .NET Framework just-in-time (JIT) compiler to native code, which is CPU-specific code that runs on the same computer architecture as the JIT compiler.
Rather than using time and memory to convert all the MSIL in a portable executable (PE) file to native code, it converts the MSIL as it is needed during execution and stores the resulting native code so that it is accessible for subsequent calls.
The runtime supplies another mode of compilation called install-time code generation. The install-time code generation mode converts MSIL to native code just as the regular JIT compiler does, but it converts larger units of code at a time, storing the resulting native code for use when the assembly is subsequently loaded and executed.
As part of compiling MSIL to native code, code must pass a verification process unless an administrator has established a security policy that allows code to bypass verification. Verification examines MSIL and metadata to find out whether the code can be determined to be type safe, which means that it is known to access only the memory locations it is authorized to access.

What is Set-at-a-time or Set-oriented?

The High level or Non-procedural DML can specify and retrieve many records in a single DML statement. This retrieve of a record is said to be Set-at-a-time or Set-oriented. (More...)

Which property needs to be set for script manager control to extend the time before throwing time out expection if no response is received from the server?

AsyncPostBackTimeout Property needs to set which gets or sets a value that indicates the time, in seconds, before asynchronous postback time out if no response is received from the server.

The default value of this property is 90 second. We can also set the user defined error message using asyncpostbackerrormessage property (as shown in above code) for time out. (More...)

Why does my Windows application pop up a console window every time I run it?

Make sure that the target type set in the project properties setting is set to Windows Application, and not Console Application. If you're using the command line, compile with /target:winexe, not /target:exe. (More...)

Are the actual permissions for the application defined at run-time or compile-time?

The CLR computes actual permissions at runtime based on code group membership and the calling chain of the code. (More...)

How can we Move to Next and Previous Record using BindingSource Class

bindingSource1.MovePrevious() to move to previous record. (More...)

Real software is developing a speech-based user interface for blind people. However, speech based interface are difficult to design and time given by the client is short. To develop a functional interface without any errors, the company wants to first evaluate the prototype. They used the storyboard technique to demonstrate the functionality of the application. However, this technique was unable to demonstrate the interactive feature of the application. Analyze and provide solution for the above scenario?

1, The design team of Real software should have used the Sketching technique because storyboard technique would only provide the flow and features of the interface.

2, The design team of Real software should have used the Horizontal Prototyping because storyboard technique would only provide the flow of the interface.

3, The design team of Real software should have used the Wizard of Oz technique because storyboard technique would only provide the flow and features of the interface

4, The design team of Real software should have used the Vertical Prototyping because storyboard technique would only provide the flow of the interface.

How to get @@ERROR and @@ROWCOUNT at the same time?

If you check @@Rowcount after Error checking statement it will give the result as 0 and if you check @@Recordcount before the error checking statement then @@Error will not return any value. To get @@error and @@rowcount at the same time, include both in a select query and store it in a local variable in a single query
