1 Change the message displayed It should be an easy matter to alter the message displayed in the label as the WinForms program (Activities 1 3) runs (simply change the text assigned to the label in the last line added to the event-handler) For example, try changing the word Hello to Good day You can also change the order in which the text is strung together For example, instead of adding the user s name after the word Hello, you could attach some other message after the user s name such as Alistair, welcome to Visual Basic NET Note that in order to do this, we need to change the order that the text assigned to the label appears in instead of <Message> & Name, we would use Name & <Message>, replacing <Message> with whatever text we wanted to add 2 Change the appearance of the form or controls While we design a WinForms form visually (before we add any code to it) we can make any of a wide range of alterations Try changing the sizes of the controls added to the form or the form itself, or alter other properties Experiment with the form in design mode, changing the font and colour properties of the controls or form 3 Add new controls You can add additional controls to a WinForms form, and can assign eventhandlers to these if required Try adding a second button to the form (call it btnGoodbye) and con guring it (change its Name and Text properties and make it a similar size to the rst button) You may wish to move the rst button or resize the form to make space for the new one Once you have done this, add an event-handler to this button (double-click on it) so that when the user clicks on it, they are again asked for their name and an appropriate Goodbye message is applied to the label Remember to save your work after making any signi cant change to the program, and especially before you try running the program

should be performed at every stage of the development process, but it is often considered to be speci cally a testing phase task Con guration management: implementation con guration management is an activity in which different versions of the components of a system are assigned to speci c versions of the system (eg the English Language version, the Small Business version, etc) and the changes in these versions are managed to ensure that incompatibilities and inconsistencies do not creep into a product Structure diagram: design a structure diagram shows how software components are assembled into sub-systems and systems Inde nite loop: implementation an inde nite loop is a software structure in which a sequence of program statements are repeated until some condition becomes true Regression test: testing and maintenance a regression test is a software test that is done to ensure that changes made to a system do not have any adverse side-effects on areas that have been successfully tested already Actor: requirements analysis an actor is a person or system that interacts with a software system in a use-case 2 A loose chronology of programming languages and styles is: Imperative programming the basic principle of programming by issuing instructions to a processor Assembly-language programming programming by writing symbolic instructions that are mnemonic names for speci c processor instructions Spaghetti programming a derogatory term used to describe the almost chaotic nature of imperative programs written in a high-level language in which repeated changes and maintenance had made the sequence of instructions confusing and error-prone Structured programming a form of programming introduced in the 1960s (after proposals by Edsgar Dijkstra) to eliminate the confusion and error-proneness of spaghetti programming Structured programming was the rst attempt to bring sound engineering principles into software development Object-oriented programming (not asked, but ) a method of programming characterized by the creation of new data types that encapsulate the attributes and behaviour of speci c components of a software system Visual programming either programming by creating diagrams that describe the structure and sequence of a task, or (more commonly) building software systems by creating parts of them using a graphical form of interaction that can remove some of the drudgery of developing user-interfaces
