Specification and Task
(Covering elements - ICTPRG418 - 1.1, 1.2, 1.3, 2.1, 2.2, 2.3, 2.4, 2.5, 3.1, 3.2, 4.1, 4.2, 4.3, 5.1, 5.2, 5.3, 6.1, 6.2, 6.3, 6.4, 6.5, 6.6)
Driving Knowledge Test Program contain 3 parts:
1) Login
2) Question
3) Test Knowledge and Result
User will login to the system to access the “Driving Knowledge Test” program. According to level, user will get access for 2nd and 3rd part of that. Admin user can Add/Update/Delete question and test their knowledge. Ordinary user only can test their knowledge and check the result.
Using Visual studio and VB.net create a windows application for the “Driving Knowledge Test “. Consider the following naming, layout and commenting conventions when coding:
i) Naming convention
• Begin each separate word in a name with a capital letter, as in FindLastRecord and RedrawMyForm.
• Begin function and method names with a verb, as in InitNameArray or CloseDialog.
• Begin class, structure, module, and property names with a noun, as in EmployeeName or CarAccessory.
• Begin interface names with the prefix -I-, followed by a noun or a noun phrase, like IComponent, or with an adjective describing the interface's behavior, like IPersistable. Do not use the underscore, and use abbreviations sparingly, because abbreviations can cause confusion.
• Begin event handler names with a noun describing the type of event followed by the -EventHandler- suffix, as in -MouseEventHandler-.
• In names of event argument classes, include the -EventArgs- suffix.
• If an event has a concept of -before- or -after,- use a suffix in present or past tense, as in -ControlAdd- or -ControlAdded-.
• For long or frequently used terms, use abbreviations to keep name lengths reasonable, for example, -HTML-, instead of -Hypertext Markup Language-. In general, variable names greater than 32 characters are difficult to read on a monitor set to a low resolution. Also, make sure your abbreviations are consistent throughout the entire application. Randomly switching in a project between -HTML- and -Hypertext Markup Language- can lead to confusion.
• Avoid using names in an inner scope that are the same as names in an outer scope. Errors can result if the wrong variable is accessed. If a conflict occurs between a variable and the keyword of the same name, you must identify the keyword by preceding it with the appropriate type library. For example, if you have a variable called Date, you can use the intrinsic Date function only by calling DateTime.Date.
ii) Layout Conventions
Good layout uses formatting to emphasize the structure of the code and makes code easier to read.
• Use the pretty listing feature to format code with the default settings (smart indenting, 4 character indents, save tabs as spaces).
• Use only one statement per line. Do not use the Visual Basic line continuation character (:).
• Use only one declaration per line.
• If pretty listing does not format continuation lines, indent continuation lines one tab stop.
• Add at least one blank line between method and property definitions.
ii) Commenting Conventions
• Do not use comments at the end of a line of code. Put comments on a separate line.
• Begin the comment text with an uppercase letter.
• End the comment with a period.
• Insert one space between the comment delimiter (') and the comment text.
