C# Windows Form Application .net
You are a Windows developer for a data analysis company. For one of your applications you need to create a keyword searching form that asks for a filename and a keyword from the user (as shown in below figure). The form should search for the keyword in the file and display the number of lines that contain the keyword in the results group box. Your form assumes that the entered keyword is a single word. If it is not a single word, you need to create and throw an exception for that case.
Include a header that is Your Name, Math Tables
Include an "Addition Table" button
Include a "Multiplication Table" button
Both tables should use the same window for the display of their information
In the secondary window, include the following:
A comment in the code that includes the assignment name, your name, and the date
Use the file name "MathTableDisplay.htm" for the secondary window file
The header for the secondary window is "Addition Table" when the addition table is displayed
The header for the secondary window is "Multiplication Table" when the multiplication table is displayed
Example web page displays and code for the addition table are included below

display a message that indicates whether the player’s guess is correct, too low, or too high; and
prompt the user to keep on guessing until the correct value is entered
Create a try-catch structure that will handle two (2) exceptions. These are when the user inputs the following:
a number that is out of range (1 – 50)
a letter or any non-numeric character
Prompt the user so that he can guess again if an exception is
Display the number of total
Note: An invalid input (when an exception is thrown) is not considered a valid guess or attempt.

- In this exercise, you modify the Grade Calculator application from this chapter’s Apply lesson. Use Windows to make a copy of the Grade Solution folder. Rename the copy Grade Solution-Intermediate. Open the Grade Solution.sln file contained in the Grade Solution-Intermediate folder. Open the CourseGrade.vb file. The DetermineGrade method should accept an integer that represents the total number of points that can be earned in the course. (Currently, the total number of points is 200: 100 points per test.) For an A grade, the student must earn at least 90% of the total points. For a B, C, and D grade, the student must earn at least 80%, 70%, and 60%, respectively. If the student earns less than 60% of the total points, the grade is F. Make the appropriate modifications to the DetermineGrade method and then save the solution. Unlock the controls on the form. Add a label control and a text box to the form. Change the label control’s Text property to “&Maximum points:” (without the quotation marks). Change the text box’s name to txtMax. Lock the controls and then reset the tab order. Open the form’s Code Editor window. The txtMax control should accept only numbers and the Backspace key. Code the appropriate procedure. The grade should be cleared when the user makes a change to the contents of the txtMax control. Code the appropriate procedure. Modify the frmMain_Load procedure so that each list box displays numbers from 0 through 200. Locate the btnDisplay_Click procedure. If the txtMax control does not contain a value, display an appropriate message. The maximum number allowed in the txtMax control should be 400; if the control contains a number that is more than 400, display an appropriate message. The statement that calculates the grade should pass the maximum number of points to the studentGrade object’s DetermineGrade method. Make the necessary modifications to the procedure. Save the solution and then start and test the application.arrow_forwardEach of the following files in the Chapter.04 folder of your downloadable student files has syntax and/or logical errors.

- Open the Calories Solution.sln file contained in the VB2017\Chap08\Calories Solution folder. Open the Code Editor window and locate the btnDisplay_Click procedure. The procedure declares and initializes a one-dimensional array named intCalories. The array stores the numbers of daily calories consumed. The procedure should calculate and display the average number of calories consumed; use the Math.Round method to round the average to an integer. (You learned about the Math.Round method in Chapter 6.) The procedure should also display the number of days in which the daily calories were greater than the average, the number of days in which the daily calories were the same as the average, and the number of days in which the daily calories were less than the average. Code the procedure. Save the solution and then start and test the application.arrow_forwardPendant Publishing edits multi-volume manuscripts for many authors. For each volume, they want a label that contains the author’s name, the title of the work, and a volume number in the form Volume 9 of 9. For example, a set of three volumes requires three labels: Volume 1 of 3, Volume 2 of 3, and Volume 3 of 3. Design an application that reads records that contain an author’s name, the title of the work, and the number of volumes. The application must read the records until eof is encountered and produce enough labels for each work.
