The MenuStrip control is essentially a ToolStrip control optimized for the display of ToolStripMenu items.
The MenuStrip control derives from ToolStrip and can host all the tool strip items described in the previous lesson. Its primary function, however, is to host ToolStripMenu items.
ToolStripMenuItem controls are the controls that provide the visual representation for items on a menu. They can appear as text, an image, or both and can execute code found in their ToolStripMenuItem
7
MainStrip is added to the form by dragging and dropping from.
8
The type here text allows new items to be added
When you click on type here a pull down appears letting you select◦ Menu item◦ ComboBox◦ Separator◦ TextBox

PROPERTY DESCRIPTION
AllowMerge Indicates whether this menu strip can be merged with another tool strip.
LayoutStyle Indicates how the controls on the tool strip are laid out
ShowItemToolTips Indicates whether tool tips for individual tool strip items are displayed.
TextDirection Indicates the direction of the text in controls hosted in the tool strip.
10
PROPERTY DESCRIPTION
AutoSize Determines whether the menu item is automatically sizedto fit the text.
Checked Determines whether the menu item appears as selected.
CheckOnClick Determines whether the menu item is automatically selected when clicked
CheckState Returns the CheckState value of the menu item. CheckState can be Checked, Unchecked, or Indeterminate.
DisplayStyle Determines how the tool strip menu item is displayed.
DoubleClickEnabled
Determines whether the DoubleClick event fires.
DropDownItems Contains a collection of tool strip items (usually, but notnecessarily, tool strip menu items) that appear in the

To add other shortcut keys (e.g., <Ctrl>-F9)
14
You can add a separator to any submenu at design time by choosing Separator from the drop-down box in the menu item design interface.
Using “-”
15
Click Generated when an item is clicked or a
shortcut key is used. This is the default event
when the menu is double clicked in the
designer
DropDownOpened Occurs when Dropdown hasoOpened
Slide 16
All controls that can display a context menu expose a ContextMenuStrip property that represents the context menu associated with that control
A context menu is invoked when the user right-clicks a control.
You can set this property at design time in the Properties window.

This course contains material that
demands intense mental work and an
unusual amount of time commitment.
Student dedication is advised.
37 38
Instructor’s expectations:◦ Homework. Read chapters prior to class from the textbook◦ Expect 2-4 hours outside classroom activities; Reading◦ Participate. Ask questions. Contribute. Actively participate
in the exercises. Consider the classroom to be a mental gymnasium where it’s ok to run, fall, and get up again
◦ Take notes. Why let any idea get away? Taking notes will help you concentrate and organize your
thoughts Notes allow you to take a refresher any time in the future.
◦ Enjoy yourself. Start relaxed and you’ll leave refreshed, inspired, and recharged Forget about what’s happening at home or at work This is your time. Get all you can out of this course and have a
good time◦ Excessive Late assignments: 10% penalty from the grade
assigned for each day ( maximum 2 days)

NOCHEATHING is allowed for all materials.
Given and taken person will be punished with less notes( 0)
◦ Attendance : 70% of Lectures
◦ Special attention for the class
Covers (most of) the C# language and some of the most useful .NET API’s.
Should not be your first programming class.◦ Assume you know C++ and basic object-oriented
programming.
Requires (lots of) practice / reading.◦ C# and .NET cannot be learned thoroughly in this
brief course.
40
Require◦ do all assignments
Assignments are ◦ You will not be given a detailed grade
◦ Show me that you understand the concepts, and can write C# code
Do a project that related with technical EEE by using C# ( It is important to apply your knowledge to oneproblem-Database projects are NOT accepted)
Note : Pls dont just directly copy the code from Internet or somewhere as your project- If we know that is copiedsomewhere we will penalty its grade as 0 (zero)

Computer programming: creating a sequence of instructions to enable the computer to do something
47
Programmers do not use machine language when creating computer programs. Instead, programmers tend to use high-level programming languagesEach high-level language has its own syntax and limited set of vocabulary that is translated into machine code by a compiler
Define a task/problem
Plan your solution◦ Find suitable algorithm to solve it
◦ Find suitable data structures to use
Write code
Fix program error (bugs)

Wikipedia.org definition for C#.◦ Object-oriented.
◦ Primarily imperative or procedural.
LINQ (Language Integrated Query) adds some functional programming language capabilities.
◦ Structured (as opposed to monolithic).
◦ Strongly typed.
◦ ISO(International Organization for Standardization)and ECMA(European Computer ManufacturersAssociation) standardized.

Sample C# Console Application program:
using System;
namespace ConsoleApplication;class HelloCSharp{
static void Main(string[] args){
Console.WriteLine("Hello, C#");}
}
51 52
using System;
class HelloCSharp{
static void Main(){
Console.WriteLine("Hello, C#");}
}
Include the standard
namespace "System"
Define a class called
"HelloCSharp"
Define the Main() method – the
program entry point
Print a text on the console by
calling the method "WriteLine" of the class "Console"
53
using System;
class HelloCSharp{
static void Main(){
Console.WriteLine("Hello, C#");}
}
The { symbol should be alone on a new line.
The block after the {symbol should be
indented by a TAB.The } symbol should
be under the
corresponding {.
Class names should useHelloCsharpand start with a CAPITAL letter.
54
using System
;
class HelloCSharp {static
void Main( ) { Console. WriteLine ("Hello, C#" ) ;Console.
WriteLine ( "Hello again") ;}}
Such formatting makes the source code
unreadable.

using
◦ like import in Java: bring in namespaces
namespace
◦ disambiguation of names◦ like Internet hierarchical names and C++ naming
class
◦ like in C++ or Java◦ single inheritance up to object
static void Main()◦ Defines the entry point for an assembly.◦ Four different overloads – taking string
arguments and returning int’s. Console.WriteLine(Write)◦ Takes a formatted string: “Composite
Format”◦ Indexed elements: e.g., {0}
can be used multiple times only evaluated once
◦ {index [,alignment][:formatting]}
