PGG311T_PGM216D Faculty: ICTDept Computer Systems Formative assessment 2 Question

Background

You have been appointed as an IT programmer to develop a system that can store and manage all employees, where the program must also be able to compute statistics and various requests.For Further understanding, there is a demo provided. 

Questions 1: Create a class named Employee

• Have the following private data members :staff number, names, gender, age, salary.
• Have a default constructor and initialize data members with your own values.
• Have a method called set values which must set all data with values sent to them.
• Have an access or method (getter) for each data member.

Question 2: Load from file into array of objects button click

Create an employee object array as a global object or under public access specifier. When this button is clicked, load data from the file(data.txt) using TStream Reader or TString list or List box and load it into the array of objects through a setter method. Thereafter disable this button and enableLoad from array of objects onto listbox.

Question 3:Load from array of objects into listbox button click

When this button is clicked, load the data from an array of objects into the listbox(data in the listbox is separated by tab). The format of data in the listbox is in the form of line number, staff no, names,gender, age, salary. Take note that line number in the listbox must be generated and the gender abbreviation must be in full name.

Status bars should be published with total employees, total salaries, total males/females, date and time (see format of the output at Figure 2 or demo).

Disabled Load from array of objects into listbox button, make sort by Agebutton and panel search button clickable.

Question 4: Sort by Age button click

When Sort by age button is clicked, the data in the list box must be sorted by age (in descending order). After sorting, make sure that line numbers (first column) are restored to the original order.Take a look at figure 3 or demo.

Question 5: Search button click

When the search button is clicked, a search happens based on the staff number entered (spaces may be left by the user on the left or right of the staff number in edit box must not be an obstacle for search).

If the staff number is found indicate the line number found in the listbox on the lbl results(the font color also changes to blue), if not found also show a message on the same lbl results(the font color also changes to red).Make sure that the user enters something in the textbox, if not show error message See sample output on the screenshots below or demo.

Question 6: On click of a list box (lst Company Employees)

Note: In this question you are only allowed to retrieve data from array of objects as you cannot substitute from lst Company Employees to retrieve data. However, you are allowed to use itemIndex property of lst Company Employees in order to retrieve relevant data from array of objects.

When lst Company Employees is clicked, a form called farm info is called and updated with necessary data, based on the current line clicked in the list box. 

The data must be updated in that form(farm info) in the string grid (stg info) and list box (selt Same).

The string grid is updated with Initials and surname, born year (see format on the demo) and salary.Note the heading and content of the string grid. List box is updated with employees earning the same salary as the employee on the selected line.Take a look at Figure 7 or demo
