About Me

• Contact DetailsMark [email protected] 232556Portland SquareRoom B316

• AvailabilityMonday, Tuesday, Wednesday, Thursday – School of Computing Communications and Electronics (main campus)Friday – other work (usually off-campus)


Module Aims

• This module aims to teach you:– How to learn (self-directed)

• surface learning (memorisation of isolated facts)• deep learning (interrelated concepts)

– How to develop software:• fundamental programming concepts (e.g. events,

procedures)• how to combine these to solve problems

– How to use Visual BASIC


Module Admin• Lectures and tutorials:

– start at 5 minutes past the hour, and– aim to end at 5 minutes to the hour– if no lecturer - wait until 15 minutes past the hour then you

may leave– Turn mobile phones off.

– Ask questions or comment at any time– Feel free to talk quietly amongst yourselves

– Material (slides, handouts, etc.) available 1 hour before session, on: Soft136 web-site (mdixon.soc.plymouth.ac.uk)

• Lectures:– Don’t come in after 15 minutes past the hour.


Module FormatThe module is delivered as follows:

• Lecture: 1 hr per week, all groups, Thursdays 13:05 – 13:55

• Tutorials / Practical Session: 2 hr per weekThursdays 14:05 – 15:55

• Private study (as much as it takes – typically 3 hours/week)

• Teaching Evaluation (timely and specific)– Student Perception Questionnaire– Continuous Informal Feedback (talk to me)

Session Aims & Objectives• Aims

– introduce you to fundamental event drive programming concepts

• Objectives, by end of this week’s sessions, you should be able to:

– Add controls to a form– Create Event Handler Procedures to do things in

response to an event of a object– Put Assignment instructions in the event handler


Example: Colour Change v1Trigger (when) Actions (what)Click event of Red button

Change background to Red

Click event of Blue button

Change background to Blue

Double Click event of Result label

Change background to White

• Events:– Click: user releases

left mouse button on object

– Double Click: mouse clicked twice


VB Environment

Toolbox

PropertiesWindow

FormWindow

ProjectExplorer


Controls - ToolBox

• Design screens (forms) usingcontrols from the Toolbox:– Picture box: display diagrams & images– Label: display text that user cannot change– Textbox: allow user to enter text– Command button: allow user to initiate

actions


Properties

• Label– Name: used to identify control (not visible to user)– Caption: the text displayed on the label– BackColor: the label's background colour

• Command Button– Name: used to identify control (not visible to user)– Caption: the text displayed on the button

• Text Box– Name: used to identify control (not visible to user)– Text: the text typed in by the user


Event Handler Procedures

Option Explicit

Private Sub btnBlue_Click() Me.BackColor = vbBlueEnd Sub

Private Sub btnRed_Click() Me.BackColor = vbRedEnd Sub

Private Sub lblResult_DblClick() Me.BackColor = vbWhiteEnd Sub

Event Handler Procedure

How many Event Handler Procedures are there?

3


Option Explicit




Objects & Events

Object

Events


Assignment Instructions

• Assignment:Object.Property = Value

Me.BackColor = vbRed

Option Explicit





Example: Colour Change v2Trigger (when) Actions (what)Click event of Hello button

Put word 'Hello' in lblResult Label

Click event of Bye button

Put word 'Bye' in lblResult Label

Click event of Red button

Change background to Red

Click event of Blue button

Change background to Blue

Click event of Move button

Move text and background colour to Result2

Double Click event of Result label

Change background to White


Tutorial Exercise: Colour Change• LEARNING OBJECTIVE:

to understand objects, events, properties, and event handler procedures,

• TASK 1: Get the Colour Change v1 example (from the lecture) working. (the code is provided)

• TASK 2: Add another button (you choose the colour). (You will need to work out what code to use. Use the code provided as inspiration please ask for advice/guidance if you need it)

• Task 3: Get the Colour Change v2 example (from the lecture) working. (You work out the code)
