1 Santa Monica College Course Outline For COMPUTER SCIENCE 19, Advanced Visual Basic Programming Course Title: Advanced Visual Basic Programming Units: 3.00 Total Instructional Hours (usually 18 per unit): 54 Hours per week (full semester equivalent) in 3.00 In-Class Lab: 0 Arranged: Lecture: Date Submitted: May 2011 Date Updated: Transferability: Transfers to UC (pending review) IGETC Area: CSU GE Area: SMC GE Area: Degree Applicability: Prerequisite(s): CS 15 Pre/Corequisite(s): None Corequisite(s): None Skills Advisory(s): None I. Catalog Description This course covers advanced programming techniques using Visual Basic.NET. Topics include Structures, Classes, Events, Inheritance, and Polymorphism, Overloading, Dynamic Binding, Multiple Document Interface, Windows API, Collections, and Exception Handling. Students also learn how to interface to Databases and build Web forms. Examples of Appropriate Text or Other Required Reading: (include all publication II. dates; for transferable courses at least one text should have been published within the last five years) 1. Murach's Visual Basic 2008, Anne Boehm, Murach publishing 2009, ISBN: MSDN Website: III. Course Objectives Upon completion of this course, the student will be able to: 1. Identify the basic structures of Object Oriented Design Methodologies. 2. Apply OO Design Methodologies to develop applications in VB.NET. 3. Write Exception Handling code using centralized and distributed methods. 4. Develop Class Libraries for client use.

2 5. Use optimizations techniques to improve medium to large scale applications performance. IV. Methods of Presentation: Discussion, Lecture and Discussion, Other (Specify) Other Methods: Lecture and Discussion: Logical analysis of problems. Code analysis. V.

Methods of Evaluation: (Actual point distribution will vary from instructor to instructor but approximate values are shown.) Percentage Evaluation Method 40 % Exams/Tests - Two exams, each 20%

3 30 % Homework - Homework (Programming assignments on a weekly basis) 30 % Final exam 100 % Total VII. Sample Assignments: 1. Start a new windows forms application: Add a class module, and create a class named Car with the following 1. Properties, VIN (string), Mileage (Integer), GasLevel (Single), MaxGasLevel (Single). VIN, Mileage and MaxGasLevel are ReadOnly properties that get assigned at creation time. Write a constructor that takes a String (representing the VIN), and an Integer that stands for Mileage, and a Single value that stands for MaxGasLevel. Assign those values to the appropriate variables that represent the VIN, Mileage and MaxGasLevel properties. 10 Points 2. Events: GasLow, which has no arguments, updatedisplay which has 1 Single argument, and 1 String argument. 10 Points 3. When assigning the GasLevel, if the level is < 0, display an error message and reject the assignment. If the level is < 2.0, then Fire the GasLow event, and accept the assignment. If the new level is > the MaxGasLevel then 'fill up the tank' and display an error message showing the amount that was not used. Otherwise, just accept the new assignment. 10 Points (hint: if the current gaslevel is x and the user wants to add y gallons, check if x + y > maxgaslevel. If so, then max out the gaslevel (make it equal to maxgaslevel) and the rest is x + y - maxgaslevel). 4. Write a procedure, PumpGas that takes one argument (a number that represents the number of Gallons) and increase the gas level by that amount. 10 Points 5. Write another method Drive that takes one argument representing miles. The method increases the mileage by that argument and decrease the gas level by 10% of the miles driven (you may assume any MPG-miles per gallon). You can not drive a car with no gas, so before you change the gaslevel and mileage, check if the miles to be driven will empty the gas tank (or go beyond) and if so, drive by only the amount of miles till the tank gets empty, then the rest of the miles amount should be shown in an error message. 10 Points (hint: If the user wants to drive x miles, check how many gallons of gas x requires (x * MPG). If x*mpg > gaslevel then add gaslevel * MPG to Mileage, and then empty the gas tank, and the rest undriven miles is x - gaslevel*mpg). 6. When any property changes its value, fire the updatedisplay event

4 with the new value (all properties have a Single type), and a string representing the property name. For example, when the gaslevel changes, fire updatedisplay(newvalue,"gas Level"). 10 Points On the form add the following features (this is called the client code): 7. Textboxes where the user types in values for a car and clicks Create. 8. When the user Clicks Create, the values in the textboxes are assigned to a new object based on the Car Class. Make sure that at creation you pass values for VIN and Mileage as typed in textboxes and that you allow the object created to handle events. 10 Points 9. Another button, and a textbox are to be used where the user types a miles driven amount and clicks the button, then the Drive method of the class is called with the given value in the textbox. 10 Points 10. Write an event handler for the GasLow event that asks the user for a number of gallons to pump then activates the Pump method. 10 Points 11. All of the above buttons, use Static Event handling (using the WithEvents and Handles) 12. Write another handler for the updatedisplay event that displays, via labels, the current car dashboard data: Mileage and gas level. 10 Points 2. Using your previous hw file, add one more component. 1. Add a combo box, that shows each new car's (car or better car) VIN number. 5 points 2. Add a button, MakeCurrent which cause the car whose VIN is shown in the above combo to be current "driven" car. Note this means when you pick a car and click MakeCurrent then when you drive and or pump gas, then its done on that chosen car. 15 points 3. To complete the design, make sure you add each car you create to a collection. Implement the collection using the CollectionBase approach. When doing that, make sure you all the user to add, delete, and make current (Item method). Warning: If you do not use the CollectionBase approach you will loose all the points for this step. 60 points 4. Use buttons so that the user can choose a car and then deletes it (delete from collection and combo), add (part of step1 above). 5 points 5. When adding a new car, make sure the user is forced to pass a VIN number (no argument-less constructor in Car or BetterCar classes). Using the Collection Add method, make sure the VIN is not duplicated. If so, throw an exception. 15 points VIII. - Student Learning Outcomes 1. Using the principles of Object Oriented Programming students will develop applications that use Classes, Objects and Collections in Visual Basic. As assessed by: projects, and exams. 2. Using the tools of the Visual Basic compiler, students will develop medium

5 scale applications with multiple screens capable of error capturing. As assessed by: projects, and exams.
