Store a String Along With a String in Delphis ListBox

Delphis TListBox and TComboBox display a list of items - strings in a selectable list. TListBox displays a scrollable list, the TComboBox displays a drop-down list. A common property to all the above controls is the Items property. Items define a list of strings that will appear in the control to the user. At design-time, when you double-click the Items property, the String List Editor lets you specify string items. The Items property is actually a TStrings type descendant. Two Strings Per Item in a ListBox? There are situations when you want to display a list of strings to the user, for example in the list box control, but also have a way to store one more additional string along the one displayed to the user. Whats more, you might want to store/attach more than just a plain string to the string, you might want to attach an object to the item (string). ListBox.Items - TStrings Knows Objects! Give the TStrings object one more look in the Help system. Theres the Objects property which represents a set of objects that are associated with each of the strings in the Strings property - where the Strings property references the actual strings in the list. If you want to assign a second string (or an object) to every string in the list box, you need to populate the Items property at run-time. While you can use the ListBox.Items.Add method to add strings to the list, to associate an object with each string, you will need to use another approach. The ListBox.Items.AddObject method accepts two parameters. The first parameter, Item is the text of the item. The second parameter, AObject is the object associated with the item. Note that list box exposes the AddItem method which does the same as Items.AddObject. Two Strings for One String Since both Items.AddObject and AddItem accept a variable of type TObject for their second parameter, a line like: //compile error! ListBox1.Items.AddObject(zarko, gajic); will result in a compile error: E2010 Incompatible types: TObject and string. You cannot simply supply a string for the object since in Delphi for Win32 string values are not objects. To assign a second string to the list box item, you need to transform a string variable into an object - you need a custom TString object. An Integer for a String If the second value you need to store along with the string item is an integer value, you actually do not need a custom TInteger class. ListBox1.AddItem(Zarko Gajic, TObject(1973)) ; The line above stores the integer number 1973 along with the added Zarko Gajic string. A direct typecast from an integer to an object is made above. The AObject parameter is actually the 4-byte pointer (address) of the object added. Since in Win32 an integer occupies 4 bytes - such a hard cast is possible. To get back the integer associated with the string, you need to cast the object back to the integer value: //year 1973 year : Integer(ListBox1.Items.Objects[ListBox1.Items.IndexOf(Zarko Gajic)]) ; A Delphi Control for a String Why stop here? Assigning strings and integers to a string in a list box is, as you just experienced, a piece of cake. Since Delphi controls are actually objects, you can attach a control to every string displayed in the list box. The following code adds to the ListBox1 (list box) captions of all the TButton controls on a form (place this in the forms OnCreate event handler) along with the reference to each button. var   Ã‚  idx : integer; begin   Ã‚  for idx : 0 to -1 ComponentCount do   Ã‚  begin   Ã‚  Ã‚  Ã‚  if Components[idx] is TButton then ListBox1.AddObject(TButton(Components[idx]).Caption, Components[idx]) ;   Ã‚  end; end; To programmatically click the second button, you can use the next statement: TButton(ListBox1.Items.Objects[1]).Click; I Want to Assign My Custom Objects to the String Item In a more generic situation you would add instances (objects) of your own custom classes: type   Ã‚  TStudent class   Ã‚  private   Ã‚  Ã‚  Ã‚  fName: string;   Ã‚  Ã‚  Ã‚  fYear: integer;   Ã‚  public   Ã‚  Ã‚  Ã‚  property Name : string read fName;   Ã‚  Ã‚  Ã‚  property Year : integer read fYear;   Ã‚  Ã‚  Ã‚  constructor Create(const name : string; const year : integer) ;   Ã‚  end; ........ constructor TStudent.Create(const name : string; const year : integer) ; begin   Ã‚  fName : name;   Ã‚  fYear : year; end; -------- begin   Ã‚  //add two string/objects - students to the list   Ã‚  ListBox1.AddItem(John, TStudent.Create(John, 1970)) ;   Ã‚  ListBox1.AddItem(Jack, TStudent.Create(Jack, 1982)) ;   Ã‚  //grab the first student - John   Ã‚  student : ListBox1.Items.Objects[0] as TStudent;   Ã‚  //display Johns year   Ã‚  ShowMessage(IntToStr(student.Year)) ; end; What You Create You Must Free Heres what the Help has to say about objects in TStrings descendants: the TStrings object does not own the objects you add this way. Objects added to the TStrings object still exist even if the TStrings instance is destroyed. They must be explicitly destroyed by the application. When you add objects to strings - objects that you create - you must make sure you free the memory occupied, or youll have a memory leak A generic custom procedure FreeObjects accepts a variable of type TStrings as its only parameter. FreeObjects will free any objects associated with an item in the string list In the above example, students (TStudent class) are attached to a string in a list box, when the application is about to be closed (main form OnDestroy event, for example), you need to free the memory occupied: FreeObjects(ListBox1.Items) ; Note: You only call this procedure when objects assigned to string items were created by you.

Case Study Of Strategic Hiring- A Case Of Emirate Airlines Cabin Crew

Question: Discuss about the Case Study Of Strategic Hiring- A Case Of Emirate Airlines Cabin Crew Recruitment. Answer: Introduction Emirate is a luxury airline based in Dubai. It is known for its extravagance and graciousness in treating its customers across the world. It flies to over 150 destinations in Europe, Asia, Australia, Africa, New Zealand and the Middle East (Emirates, 2018). The report is based on the presented case study of Strategic hiring- A case of emirate airlines cabin crew recruitment. It will highlight various discussions supporting emirates talent philosophy where the recruitment drive of Emirate is highly professional in managing the situations and extracting effective people out of various candidates. The emirates recruitment strategies were aligned according to the short availability of time, in additional several challenges were faced by the recruiting team which was overcome by them. However, this relatively enabled them to achieve success by selecting the appropriate and best candidates. The report also highlights recommendation and assessment tools to assess value inventory. Discussion Emirates talent philosophy depended on its recruitment team which performed outstandingly. It handled the critical situations where working continuously three days to recruit over 1650 candidates was an immense contribution. The team members were only 15 that need to handle such crowd. The sudden situation they faced where the recruiting team focused not to disregard the companys status and the value of the shortlisted candidates and the open candidates which might affect the future reputation of the company. The recruitment team also designed the schedule to interview all the candidates in a short span of time and achieve the goal to hire the most appropriate crew for board. After such long and difficult interview session only 45 of the suitable candidates were selected. The Emirates scheduled its recruitment process in two specific categories which were presented to the candidates as open days interview and days by interview where it enabled the candidates to forward their resume through online to the company. The other open interview widens the recruitment process to all the candidates as a simple walk in interview. After the screening process the candidates will be hired on the basis of their quality perspective shown while in the interview. However, in the last moment where only 200 candidates were invited it was seen that more 1450 candidates were extra who came up to give an interview. This condition was later accepted by the recruitment drive to interview the whole crowd of candidates freshly. The recruitment team during its planned process of hiring which later extended to a bit difficult task to arrange the hiring process for a vast number of candidates over both open and invitation recruitment option. The initial challenge that was faced by the recruitment drive was invitation of the candidates which were sorted from the online recruitment process. In brief the invited candidates were the selected candidates from the first round of interview after viewing the resumes of all the individual candidate which were to be taken with the second interview in the hotel lobby of the place. The situation became awkward when along with the 200 invited candidates; more 1400 candidates joined the interview process. On top of these huge figuring candidates the time that was allotted by the recruitment team to interview the rest 200 invited candidates was only limited to 1 day which was further extended to extra 2 more days. Still it was seen as one of the biggest challenge by the team as rounding up to 1650 candidates that were to be interviewed by 15 members of the recruitment drive in 3 days. Human resource team is known to evaluate, manage and do the best for the organization keeping in mind the cost effectiveness but in the case of Emirate the turning of the plans into quick actions to respect both the company and candidates value in recruiting process. The extension of the banquet hall of the hotel to interview all the candidates in 3 continuous days made the process costly. It also results in the problem in the accommodation of all the team members as it was planned to stay in Bucharest for 1 day. A further challenge that was waiting for the recruitment drive to be answerable during the recruitment process was being questioned by the candidates on the modification of the selection process. After the modification done by the recruitment drive, the initial step that should be taken by the recruiting team was to manage firmly the invited candidates as they had to face the major challenge as they again had to fight for the selection in Emirate which mean again they had to give their interview from the beginning to achieve their dream to work with Emirate boards. For this purpose the recruitment head Krishna arranged the manger of the hotel to offer tea/coffee to the candidate with local snacks made by their chef in two snack time specifically at first at 11 am and the other at 4:30 pm. The Emirate handled to provide the candidates with the souvenir to retain the interest of the candidates and select the effective one among them. Then it needs to be decided that while in the interview period the self introduction of the Emirate to each of the interviewee will consume more time instead of at first interacting with all the interviewee. This will cut the time being wasted in the interview process ad rather using it for the effective short listing the employees required with suitable skills from the ocean of candidates. Assessment tools: In order to assess the candidates other significant value inventories there can be some suggested tools that the Emirates can use:- Grooming checking: This can be an important factor while in the profession of air hostess as they always need to look fit and perfect. The customers look to be welcomed by the attendants in the flight in an ethical and respectful manner in the same way the customer would like to be welcomed by a hostess who looks presentable and chic. Therefore, during an interview the overall presentable a candidate can represent in front of the interviewer is an observable factor. The more the person is presentable it will make the customer perceive things in an extravagance manner (Eklund, 2016). Small focus group interview: this is a type of interview that will engage a minimum number of candidates to be formed in a group and taken together for the interview process. This method is useful as it will help to recognize that to what extent the candidate is capable of standing and presenting own self in from of hundreds of customers. While taking such interview the interviewer can relocate the behavior of the other candidates sitting idle in the group interview process. It will show the skill regarding their attention, consciousness, alertness and body gestures that will be necessary when they will be hired for boarding. Scenario case interview: This is another type of interview where it can be observed that how much the candidate is depended on his skill and capability of handling a situation which might raise concerning the unplanned situation. In the interview the candidate can be offered a set of case studies where they need to pick one and quickly give their opinion and the action that can be implemented in the scene to manage the situation. It will give a quick understanding of the problem solving skill of the candidate. Recommendation to access value inventory: Professionalism- This factor needs to be evaluated at the initial stage of interview where the question to the candidate can be thrown as how did he come to know about Emirate? did the candidate had enough knowledge regarding the background of Emirate and the market new related to it and other factors that show the skill of the candidate with respect to professionalism. Emotional Quotient- The emotional quotient of individual can be different and can affect the attitude in the workplace. It is believed that higher emotional intelligence will result in high job performance. During interview asking the question relating to emotional intelligence can show the personal skill of developing strategies to overcome consequences. Cosmopolitan Outlook- the cosmopolitan outlook refers to people who are committed to variedness in their nature with the mixture of culture and different lifestyles that will help in the engagement of interacting and coping up with people in the flight. Cultural Assimilation- another essential value that drives the profession of the air hostess, as in the aviation industry it is important to be flexible in terms of travelling throughout the world with the flights schedule which requires cultural absorption skill to manipulate the needs and requirement accordingly. It also includes encountering people with variable mood such as anger, frustration and even cultural interfaces. Appreciation for diversity- During the interview this factor can be evaluated by framing questions as to get a quick answer on the diversity perspective of the individual. Aviation industry consist of operations where meeting new people from different cultural perspective is an everyday task. Conflict resolution skills- this skill again focuses on the solving of analytical skill that needs to be solved by the help of personal views and experiences that also influencing others welfare. This type of skill is useful fir the actions to be taken in the short period of time (Plant Stanton, 2016). Execution skills in stressful work situations- in this value the understanding and performing a various number of task altogether without hesitation and being any evidence for the faced difficulty is an attribute of a valuable employee. Performing multi task altogether effectively is a skill required to entry in aviation. Conclusion From the above disclosure, it can be concluded that Emirate is Dubai based airline operating in over more than 150 destinations and 140 countries. The above report shows that the customers care is the main motive that is being served by the Emirates. The skills and advancement to handle the critical situations were one of the human resource capital of Emirates. Out of 1650 candidates only 100 were selected as per the case study and finally only 45 effective candidates were short listed which were regard as the best appropriate candidates chosen after continuous 3 days of interview. The report also contains brief of 3 assessment tools specifically case study solving, grooming checking and small group interview which will help to hire the suitable employees. Emirates believe in hiring the best suitable employees after various strategic interviews in over various countries. Employing the right people is the motive. The recommendations in the end, states that the problem solving skill, c osmopolitan outlook, cultural assimilation execution skills, emotional intelligence and professionalism are the important values that one needs to consider while assessing value inventories.
