.NET Programming

Boxing is the process of converting a value type to the type object or to any interface type implemented by this value type. When the CLR boxes a value type, it wraps the value inside a System.Object and stores it on the managed heap. Unboxing extracts the value type from the object. Boxing is implicit; unboxing is explicit. The concept of boxing and unboxing underlies the C# unified view of the type system, in which a value of any type can be treated as an object.

Method overloading is when you have multiple methods in a class that have the same name but a different signature. Method overriding is similar to method overloading, with a small difference. In overriding, a method in a parent class is overridden in the child class. The method in the child class will have the same signature as that of the parent class. Since the method in the child class has the same signature & name as the method of its parent class, it is termed as overriding. In situations where you may have to explicitly call the parent class method you can use the "super" keyword and for explicitly calling the current objects method you can use the "this" keyword.

interface inheritance is a misleading term. Interface inheritance would be equivalent to the union of the method signatures of interfaces ( no typo here, an interface may implment multiple other interfaces)

Class inheritance - single hierarchy (in C#), and not only the methods are inherited, but also the data members. (interface in C# cannot define data members)

Java is always the best.

Java is great for Enterprise while desktop is the place for .Net

It is a collection of classes and services.It exists as a

layer between.NET applications and underlying operating

system.

ie it encapsulates the basic functionality that was

earlier built into programming languages such as debugging

and security services.

Tapuwa mubare is a multi millionaire young man from Mutare Zimbabwe who acquired most of his wealth through designing cutting edge planes and space crafts.His career started when he was only 17 by using CAD software to design crafts and new machinery. He managed to acquire a contract with Nasa and is being paid £20 million a year for new designs. The latest space jumbo airpeller 228 was masterminded by him and it will be ready for takeofff to space in a year's time. He racked contracts from China , Russia , Iran , UK and the United States for his work is now reported to be worth £145 million at the age of 21. His empire is expected to grow in an alarming rate, and he will be worth £500 million by the age of 26.

non-deterministic means not predicable, hence non-deterministic finalization means the finalization (removing objects from memory) cannot be determined when that will happen

The hugely simplistic version is that every time it garbage-collects, it starts by assuming everything to be garbage, then goes through and builds a list of everything reachable. Those become not-garbage, everything else doesn't, and gets thrown away. What makes it generational is that every time an object goes through this process and survives, it is noted as being a member of an older generation (up to 2, right now). When the garbage-collector is trying to free memory, it starts with the lowest generation (0) and only works up to higher ones if it can't free up enough space, on the grounds that shorter-lived objects are more likely to have been freed than longer-lived ones. Non-deterministic finalization implies that the destructor (if any) of an object will not necessarily be run (nor its memory cleaned up, but that's a relatively minor issue) immediately upon its going out of scope. Instead, it will wait until first the garbage collector gets around to finding it, and then the finalisation queue empties down to it; and if the process ends before this happens, it may not be finalised at all. (Although the operating system will usually clean up any process-external resources left open - note the usually there, especially as the exceptions tend to hurt a lot.)

If you are having the problem i think, you need to find the maching you logged into Source Safe with and open then close the database this will close the Login session that didn't close properly and you can return to normal use. FYI: Under normal use when you close the application it will log you out. Note: If the machine that you used is unavalible for any reason all you need is a machine with the same computer name. good luck If you are having the problem i think, you need to find the maching you logged into Source Safe with and open then close the database this will close the Login session that didn't close properly and you can return to normal use.

Microsoft's web services architecture, pronounced dot-net .NET is the brand name for a set of proprietary Microsoft frameworks and technologies founded on XML web services standards. Standards compliance means that applications written using .NET should interoperate with those written in rival architectures, such as J2EE, the distributed application infrastructure based on Sun's Java language. However, interoperability is not portability; .NET applications will only run on Microsoft platforms, such as Windows Server or Windows XP and later.

Ole DB is a mechanism that allows applications to connect to databases that support the Ole DB framework. This is a Windows technology. This technology allows application developers to write software that can target any database, making the code for database manupulation simpler and easier to implement. As an aside, Ole, which used to stand for Object Linking and Embedding, was dropped to "Ole" when Microsoft discovered you cant trademark an acronymn.

system analysis and design is a process in doing a program........ and there a step on how to do a program first you study the data , second is analyze the data or program, third is draw your data, fourth is coding the data, next is testing the data that you do,next is implication and the last is maintenance. :-) hehehe

By definition, all .NET Framework code is managed. You only have to worry about unmanaged code if you reference COM libraries or, of course, write any unmanaged code yourself.

There is no such thing as a .org file. .org is a top level domain extension like .com, .gov, .edu, and .net. It is used for website access and browsing the web, not saving files.

For providing context-sensitive help to VB5 and Vb6 applications, we can set the property called App.helpfile and hook-up the helpfile with the application.

For VB 5 and above one can use .hlp files as help files. For Vb6 and above one can use .chm files as application help files.

In VB.NET this property is not used for providing F1 help to the applications. Instead a control named - Helpprovider is dropped on the form and configured for associating help topics frm the .chm file to the form controls.

Not possible.

When we require some data frequently, that data can be stored into memory instead of database and it access from memory is called cashing.

i dont knoe can u explian it
