Introduction to Visual Basic 6.0

What is Visual Basic?

Creates Graphic User Interface (GUI) Creates applications for the Microsoft Windows OS Major components:

1. Forms

2. Controls

3. Commands

4. Objects


History of Visual Basic

• Alan Cooper developed Visual Basic in 1988 and sold to Microsoft

• VB1 Debuts at Windows World in March 20,1991

• VB2 Debuts in November 1992

• VB3 Debuts in June 1993

• VB4 Debuts in October 1996

• VB5 Debuts in April 1997

• VB6 Debuts in October 1998



What programming language is Visual Basic based on?

BASIC (stands for Beginner’s All Purpose Symbolic Introduction Code)


Starting Visual Basic 6.0

• Click on Start • Select Programs • Select Microsoft Visual Studio 6.0 • Click on Microsoft Visual Basic 6.0 • Click on Open


Visual Basic 6.0 Programming Window



What is a Form Window?

The form window holds the application’s

form background and all its user controls,

such as command buttons.

What is a Toolbox?

The toolbox contains the controls that you

place on the Form Window. All the controls

appear on the toolbox.


Creating Your First Application

• Design your form as below:

Text Box Command Button

Command Button

Label Text Box


Writing the program

• Double click on the command button

ADD


• Enter the following code

Label5= val(text1) + val(text2)

To display answer Number 2

Number 1

Value

Writing the program


• Enter number 1 (any number) • Enter number 2 (any number)

Click on ADD

Running the program


• Click on ADD Command button

Running the program


Calculator


Controls in the Toolbox

• Label – A label control is used to display text that a user can’t

change directly.

• Textbox – A textbox control is used to input data from the user at run

time.

• Command button – A command button is used to perform an event at run time.


Addition of three numbers


Area of a Triangle


Code

• Double click on AREA • Type, Private Sub Command2_Click() Text 3 = 0.5 * val(Text1) * Val(Text2) End Sub


Area of Circle


Code

• Double click on AREA • Type, Private Sub Command2_Click() Text2 = 3.14 * (Val(Text1) ^2) End Sub


Discount


Code

• Double click on Discount • Type, Private Sub Command2_Click() Text3 = Val (Text1) * (Val(text2) / 100) End Sub


Code

• Double click on Total • Type, Private Sub Command3_Click() Text4 = Val(Text1) - Val(Text3) End Sub


Exercise


IF …..Then…..Else Statement

• If...Then...Else statement is used for controlling the program flow.

• To control the VB program flow, we can use various conditional operators

and logical operators.


Conditional Operators

Operator Meaning

= Equal to

> Greater than

< Less Than

< > Not Equal to • The conditional operators compares data

values and then decide what action to take.


Examples

A=10, B=15 Operations Result Is A=B ? FALSE / NO Is A>B ? FALSE / NO Is A<B ? TRUE / YES Is A< >B ? TRUE / YES


Logical Operators

AND: Both sides must be true Side A Side B Result TRUE TRUE ? TRUE TRUE FALSE ? FALSE


Logical Operators

OR: One side or other must be true Side A Side B Result TRUE TRUE ? TRUE FALSE TRUE ? TRUE FALSE FALSE ? FALSE


The general format for the if...then...else statement is

If conditions Then

VB expressions

Else

VB expressions

End If


Program for next class.. Design Mode

Text Box Command Button


Run Mode

• When the program is Run, if the user enters value greater than 8.


Run Mode

• When the program is Run, if the user enters value less than 8.


Coding..

• Double Click on OK Private Sub Command1_Click() If Text1 > 8 Then MsgBox (“You are late !!”) Else MsgBox (“You are not late !!”) End If End Sub


Form Color

Option1 Option3 Option5

Option2 Option4 Option6


Code

• Double click on Option1

Private Sub Option1_Click() If Option1.Enabled = True Then Form1.BackColor = vbRed End If End Sub


Code • Double click on Option2

Private Sub Option2_Click() If Option2.Enabled = True Then Form1.BackColor = vbBlue End If End Sub



Private Sub Option3_Click() If Option3.Enabled = True Then Form1.BackColor = vbWhite End If End Sub


Code


Private Sub Option4_Click() If Option4.Enabled = True Then Form1.BackColor = vbBlack End If End Sub


Code


Private Sub Option5_Click() If Option5.Enabled = True Then Form1.BackColor = vbYellow End If End Sub


Code


Private Sub Option6_Click() If Option6.Enabled = True Then Form1.BackColor = vbGreen End If End Sub


Form Font

Label1

Option 2

Option 3

Option 4

Option 5

Option 6

Option 1


Code


Private Sub Option1_Click() If Option1.Enabled = True Then Label1.FontBold = True End If End Sub


Code


Private Sub Option2_Click() If Option2.Enabled = True Then Label1.FontItalic = True End If End Sub



Private Sub Option3_Click() If Option3.Enabled = True Then Label1.FontUnderline = True End If End Sub



Private Sub Option4_Click() If Option4.Enabled = True Then Label1.FontSize = 10 End If End Sub


Code




Visual Basic Fundamentals

• Numeric constants: integer, long integers, single -

precision real (or floating point), double-precision real (or

floating point)

• String constants

• Variables

– Name must begin with a letter, letters and numbers can be included, as well as underline character ( _ )

– Data-typing characters ( %, &, !, #, $) are not permitted

– Maximum length of name = 255characters


Data types and data declaration

• Data types supported: Integer, Long, Single, Double, String, Boolean, Byte, Currency, Date

• Data declaration uses the Dim statement Dim variable_name_1 As data_type_1,

variable_name_2 As data_type_2, etc.

Example:

Dim firstname as string


Branching and Looping

• Relational operators and logical expressions

– Relational operators: = , < > , < , <= , > , >=

– Logical expressions, e.g., a > b, c = d + 2, x >= y,

can be either true or false


If ..Then..Else..Endif Statement

vbExclamation, “Access Granted”) Else password = MsgBox (“Incorrect Password!!”, vbRetryCancel +

vbCritical, “Access Denied”) If password = vbRetry Then Text1 = "" Text1.SetFocus End If End If End Sub


Select Case • The Select Case structure tests whether the value

of an expression falls within predetermined ranges. • Syntax Select Case expression Case testlist {instructions} Case testlist {instructions} :

Case else {instructions} End Select


Example: Program to enter your age

Text Box


• Double click on

Dim age as Integer age=text1 Select case age case 1 to 12 Msgbox (“Child”) case 13 to 19 Msgbox (“Teenager”) case is > 19 Msgbox (“Adult”) case else Msgbox (“Impossible”) End select

OK


Example: Program to insert any string


Program Explanation

• Use Select Case to do the program • When the user enters blank string

– Display Message box “Null / Blank String”

• When the user enters a or e or I or o or u – Display Message box “Vowel”

• When the user enters a to z – Display Message box “Consonant”

• When the user enters 0 to 9 – Display Message box “Numeric Digit”

• When the user enters any other characters such as $ or @ or * – Display Message box “Special Character”


• Double click on Dim str As String str = Text1 Select Case Left(str, 1) Case “” MsgBox (“Null String”) Case “A”, “E”, “I”, “O”, “U”, “a”, “e”, “i”, “o”, “u” MsgBox (“Vowel”) Case “A” To “Z”, “a” To “z” MsgBox “Consonant” Case “0” To “9” MsgBox “Numeric Digit” Case Else MsgBox “Special Character” End Select

OK


Hotel Example


Private Sub Command1_Click()

Select Case Combo1 Case “Single” Text1 = (Val(Text2) * 500) & “ Baht ” Case “Single A/C” Text1 = (Val(Text2) * 1000) & “ Baht ” Case “Double” Text1 = (Val(Text2) * 800) & “ Baht ” Case “Double A/C” Text1 = (Val(Text2) * 1500) & “ Baht ” Case “HoneyMoon Suite” Text1 = (Val(Text2) * 2000) & “ Baht ” End Select End Sub
