Design a notepad application in WPF.

Using disconnected architecture in ADO.NET perform crud operations on the Student Registration form

Write a program that does the following for 15 students:

• Reads in 3 marks for each student (marks must be between 0 and 100)

• Calculates and displays the highest mark for each student.

Update your solution to also read in the name of each student, and when displaying the overall highest mark, the name of the relevant student should also be displayed.

Update your solution to make use of the getMark method (written for task 3 of this prac, code copied to this solution).

You can also consider creating other user defined methods to update your solution.

Create a program whose Main() method prompts a user for length and width of a room in meter. Create a method that accepts the values and then computes the estimated cost of painting the room, assuming the room is rectangular and has four full walls and the walls are 2.6 meter high. The rate for the painting job is R20 per square meter.

Return the estimated cost to the Main() method, and display it.

Write a user defined method named getMark that can be used to get a valid mark from the user. Your method must continuously ask the user for a mark, until a valid mark is entered (valid marks are between 0 and 100). If a user enters an invalid mark, display an error message before asking for a valid mark to be entered. The method must return the valid value to the calling program.

Write a user defined method named isPass that can be used to determine whether a mark is a pass mark (greater or equal to 50). The method must take as input a mark, and return a boolean, indicating whether the mark was a pass mark.

Create a user defined method named calcCost() that accepts two values as input (length and width), and then computes the estimated cost of painting the room, assuming the room is rectangular and has four full walls and the walls are 2.6 meter high. The rate for the painting job is R20 per square meter. Your method should return the estimated cost to the calling method.

Create a program whose Main() method prompts a user for the length and the width of a room in meter, then calls calcCost to calculate the estimated cost. Once calculated, you should display the estimated cost.

Write a user defined method named displayDetails() that declared and assigns values to local variables for your nick name, your student number, and your favourite movie. The method should also contain 3 WriteLine statements to display your nick name, your student number, and your favourite movie. Write a program that displays the text Hello World and then calls the displayDetails() method to display your information

System Background

A company approached you to develop a Software Application to handle transactions performed by a user on their accounts. Each user has a balance that indicates the current amount of money in the account. The following transaction operations can be performed by a user:

• Deposit an amount into the account.
• Withdraw an amount from the account.
• View the current balance of the account.
• Cancel a transaction.

System Requirements

The company asked you to develop a C# Console Application prototype to simulate the transactions for one user.

This user should have an initial (hard-coded) balance of R 10 000.00

The user should be presented with the following options to choose a specific transaction that needs to be performed:
