The document discusses exception handling in C# programs. It explains that exceptions are errors that occur during program execution. The C# try, catch, and finally keywords are used to handle exceptions. The try block contains code that might cause exceptions. The catch block handles specific exception types. The finally block contains cleanup code that always executes. Built-in exceptions like DivideByZeroException are part of the .NET Framework. Exception handling prevents program crashes and allows graceful handling of errors.
This is a little presentation for those interested in learning C#. I find it useful to present this to new clients to see where they are at in the the programming curve.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

TESDA TM1 REVIEWER FOR NATIONAL ASSESSMENT WRITTEN AND ORAL QUESTIONS WITH A...
Visula C# Programming Lecture 8
1. Get set property
class Thought
{
private int a;
public int xy {
get {
return a;
}
set {
a = value;
}
}
}
class Program
{
static void Main( string[] args ){
Thought t = new Thought();
t.xy = 23;
Console.WriteLine("value=“+t.xy);
Console.ReadLine();
}
}
2. Abstract Class
Motivation: if you think no object of a class should be
created, declare the class abstract
In general, an abstract class is a placeholder in a class
hierarchy that represents a generic concept
The use of abstract classes is a design decision; it helps us
establish common elements in a class that is too general to
instantiate
Vehicle
Car
Boat
Plane
2
3. Abstract Classes: Syntax
Use the modifier abstract on a class header to declare an
abstract class, e.g.,
abstract class Vehicle
{
// …
public abstract void Move();
}
class Car : Vehicle
{ //…
public void Move()
{
Console.WriteLine( “Car is moving!” );
}
}
abstract class StaffMember
{
// …
public abstract double Pay();
}
3
4. Abstract Class: Some Properties
An abstract class cannot be instantiated
but you can define a reference of an abstract class
Only abstract classes can contain abstract
methods
The child of an abstract class must override
the abstract methods of the parent, or it too
must be declared abstract
4
5. C# Contains Many Other Features to
Further Refine the Definition of a Class
Sealed class or method
if you declare a class or method sealed, then the
class or method cannot be extended
Operator overloading
you can define operators for a class so that
operations look more like a normal arithmetic
operation
5
6. Using Interface for Multiple Inheritance
Java/C# decision: single inheritance,
meaning that a derived class can have only
one parent class
To take the advantages of multiple
inheritance, Java/C# defines interfaces,
which give us the best aspects of multiple
inheritance without the complexity
6
7. C# Interface
A C# interface is a collection of methods, and properties
it can actually include other types of definitions
These methods and properties have no implementation
An interface is used to formally define a set of methods that a
class will implement
An interface captures one aspect of a class
If class D is derived from class B, then you should feel comfortable in
saying an object of D is also a B
If class D implements interface I, then you should feel comfortable in
saying an object of D has I perspective
7
8. Interfaces: Syntax
interface is a reserved word
public interface IComplexity
{
int
Level { get; set; }
}
public interface IDisplayAble
{
void Paint();
}
// inherits Question, implements two interfaces
class MultiChoice: Question, IComplexity, IDisplayAble
{
public void Paint() {...}
public int Level {...}
public string GetQuestionPart() {}
public string GetAnswerPart() {}
}
8
9. Interfaces
Methods in an interface have public visibility by default
An interface cannot be instantiated
A class implements an interface by
stating so in the class header after :
A class can implement multiple interfaces: the interfaces
are separated by commas
If a class asserts that it implements an interface, it must
define all methods in the interface or the compiler will
produce errors
A class that implements an interface can implement
other methods as well
9
10. Polymorphism via Interfaces
An interface name can be used as the type of
an object reference variable
IDoable obj;
The obj reference can be used to point to
any object of any class that implements the
IDoable interface
The version of doThis that the following line
invokes depends on the type of object that
obj is referring to:
obj.doThis();
10
11. An Example
ISpeak guest;
guest = new Professor();
guest.Speak();
guest = Dog();
guest.Speak();
ISpeak special;
special = new Professor();
special.Pontificate(); // compiler error
ISpeak special;
special = new Professor();
((Professor)special).Pontificate();
public interface ISpeak
{
public void Speak();
}
class Faculty {…}
class Professor: Faculty, ISpeak
{
//
public void Speak()
{…}
public void Pontificate()
{…}
}
class Animal {}
class Dog: Animal, ISpeak
{
//
public void Speak()
{
…
}
}

12. Exception Handing
Exception handling is an in built mechanism
in .NET framework to detect and handle run
time errors.
The .NET framework contains lots of standard
exceptions.
The exceptions are anomalies that occur
during the execution of a program.
They can be because of user, logic or system
errors.
12
13. Exception Handing
If a user (programmer) do not provide a
mechanism to handle these anomalies, the
.NET run time environment provide a default
mechanism, which terminates the program
execution.
13
14. Syntax
C# provides three keywords try, catch and
finally to do exception handling.
try
{
// Statement which can cause an exception.
}
catch(Type x)
{
// Statements for handling the exception
}
finally
{
//Any cleanup code
}
14
16. Exception handled
class MyClient
{
public static void Main()
{
int x = 0;
int div = 0;
try
{
div = 100/x;
Console.WriteLine("This line in not executed");
}
catch(DivideByZeroException de){
Console.WriteLine("Exception occured");
}
finally{
Console.WriteLine("Finally Block");
}
}}
Console.WriteLine("Result is {0}",div);
