1 Teaching an Introductory Programming Class
Using Visual Basic .NET

2 We are... Anita C. Millspaugh Professor, Computer Information Systems
Mt. San Antonio college Julia Case Bradley Professor Emeritus, Computer Information Systems Mt. San Antonio College Bradley/Millspaugh texts: VB 4, VB 5, VB 6, Advanced VB, Java and the new VB .NET Spring 2002

3 You… Teach Visual Basic 6? Are planning to teach Visual Basic .NET?
Have taught an OOP language such as Java, SmallTalk, or C++? Spring 2002

4 Our Goals for Today Help you transition from VB 6 to VB .NET
Look at the differences between Visual Basic 6: object based; event driven Visual Basic .NET: object oriented Introduce the new Visual Studio IDE (integrated development environment) Show the changes to the language and the new features Spring 2002

5 Our Approach This is an introductory programming course Main topics:
Program planning Programming logic Variables, constants, calculations, decisions, loops, data files Language syntax Coding standards Testing and debugging The VB .NET course still covers these topics, with OOP concepts embedded throughout. Spring 2002

6 What is the .NET Framework?
Platform for building and running applications Designed for cross-platform compatibility Common Language Runtime (CLR) Share methods and objects from different languages Many languages to choose from — VB, C#, COBOL, Fortran, J# … Spring 2002

7 The Biggest Change in VB .NET — OOP
A new mind set New keywords: Inherits Overrides Overloads Terminology introduced in Chapter 1 Concepts covered in Chapter 6 Spring 2002

8 The Second Biggest Change — Web Forms
Programming for the Web vs. Windows New set of controls Client side vs. server side Web page layout Very simple projects presented in Chapter 9 Spring 2002

9 The Third Biggest Change — Data File Handling
Database uses ADO .NET (Chapter 10) No Data control “Simple” program is more difficult Binding is more robust and likely to be used by “real programmers” Must write code for navigation Simple data files use streams (Chapter 11) Spring 2002

10 Chapter 1 — Introduction Topics Covered
Objects, Methods, and Properties The Visual Studio IDE Planning a Project Creating a Project Labels and Buttons Code Syntax and Logic Errors Help Spring 2002

11 Chapter 1 — Changes New IDE Spring 2002

12 Chapter 1 (continued) Terminology VS IDE Solution Explorer Form Designer Editor window Tabbed display is the default for the IDE AutoHide toolbox; can be “pinned” open Spring 2002

13 Chapter 1 (continued) Push Pin Tabbed Window Locked Control
Spring 2002

14 Chapter 1 (continued) A solution can contain multiple projects
Forms, classes, and code modules have a .vb extension The IDE automatically creates a folder for the project Spring 2002

15 Chapter 1 (continued) Form Designer Similar to VB 6
Double-Click a control in the toolbox: New default-sized control Appears on top of a selected control Top-left of the form if no control is selected Locked controls have a dark border when selected Command Buttons are now Buttons Use “btn” for prefix No more Caption property — now it is Text Spring 2002

16 Chapter 1 (continued) The Editor window (formerly the Code window)
Lots more IntelliSense help; can be confusing Declarations section replaces General Declarations Class List and Method List - Selecting the object and event is somewhat different Collapsible Regions in code Spring 2002

17 Chapter 1 (continued) Tabs Method List Class List Collapsed Region
Procedure Spring 2002

18 Chapter 1 (continued) Complications:
Changing the name of the form requires the project’s startup object to be changed PrintForm is no longer supported IDE Print does not offer Form Image or Form Text No edit-and-continue execution – Must restart (recompile) if edits are made during break time Spring 2002

19 Chapter 1 (continued) Form and controls no longer have Caption property Forms, buttons, labels all use the Text property The Alignment property becomes TextAlign The maximum length of identifiers is 16,383 All new Help — MSDN Redesigned Object Browser Me.Close() Spring 2002

20 Chapter 2 — More Controls Topics Covered
Check Boxes Radio Buttons Group Boxes Picture Boxes Designing an Interface Setting the Tab Order Setting up keyboard access keys (shortcuts) Spring 2002

21 Chapter 2 — Changes No more Image control, Line control, or Shape control Use PictureBox for graphics; Label for lines OptionButton becomes RadioButton Frame becomes GroupBox AcceptButton and CancelButton are properties of the form Set the form’s StartPosition property; no more Form Layout Window Spring 2002

22 Chapter 2 (continued) PictureBox controls
Use Image property to hold a graphic Set SizeMode property to StretchImage — replaces Stretch property of Images CheckBox controls Value property becomes the Checked property (Boolean) It’s event is CheckChanged Great new method for setting tab order Spring 2002

23 Chapter 2 (continued) View / Tab Order Spring 2002

24 Chapter 2 (continued) New component tray holds non-visible controls
To add ToolTips, add a ToolTip control to the component tray New ToolTip on ToolTip1 property is added to the form and all controls Text boxes have a Clear method txtName.Clear() txtName.Text = “” Focus method replaces SetFocus txtName.Focus() Spring 2002

25 Chapter 2 (continued) Many colors available through the Color class
lblMessage.ForeColor = Color.Blue Color.Red Color.Yellow Color.Aquamarine Color.Bisque Color.Chocolate Color.Cadetblue … and dozens more Spring 2002

26 Chapter 3 — Variables, Constants and Calculations Topics Covered
Variables, constants, calculations Data types Converting text input to numeric Formatting output Error Handling (Exceptions) Message Boxes Spring 2002

27 Chapter 3 — Changes Strongly Typed Data Option Strict On
– Enforces strong data typing Data Types Short (old Integer) Integer (old Long) Decimal (Currency is gone) Object ( Variant is gone) Date (replaces DateTime) Spring 2002

28 Chapter 3 (continued) Initialize a variable at declaration Dim intMax As Integer = 100I Dim decRate As Decimal = 0.08D Declare multiple variables at once Dim intCount, intNumber As Integer Convert all input to correct data type (Do not use Val function) decSale = CDec(txtSale.Text) CDec and CInt — Can parse: $ , () + - CInt rounds to nearest EVEN number Spring 2002

29 Chapter 3 (continued) New assignment Operators += –= *= /= &=
decTotal += decSale Structured Exception Handling Try (Code that could cause an exception) Catch [excName As excType] (Code to handle the exception) Finally (Code to execute in any case) End Try We can catch input errors before covering If statements! Spring 2002

30 Chapter 3 (continued) MessageBox class MessageBox.Show(Arguments)
Several choices for argument list Introduces concept of Overloaded functions Multiple signatures to choose from MessageBox.Show(TextMessage) MessageBox.Show(TextMessage, TitlebarText) MessageBox.Show(TextMessage, TitlebarText, _ MessageBoxButtons) MessageBox.Show(TextMessage, TitlebarText, _ MessageBoxButtons, MessageBoxIcon) Spring 2002

31 Chapter 3 (continued) MessageBox Icons and buttons
Enumeration of constants Spring 2002

32 Chapter 4 — Decisions and Conditions Topics Covered
Conditions / Relational Operators Block Ifs Compound Conditions Validation Message Boxes that return the user response Debugging Spring 2002

33 Chapter 4 — Changes Block IF unchanged
Conditions — always compare like data types If CInt(txtInput.Text) > 10I Then String ToUpper and ToLower methods (replace UCase and LCase functions) If txtInput.Text.ToUpper = “YES” Spring 2002

34 Chapter 4 (continued) MessageBox.Show method returns an object of type DialogResult Dim dgrResponse As DialogResult dgrResponse = MessageBox.Show(”Shall we?", _ "The Question", MessageBoxButtons.YesNo, _ MessageBoxIcon.Question) If dgrResponse = DialogResult.Yes Then MessageBox.Show("You said Yes!") Else MessageBox.Show("You said No!") End If Spring 2002

35 Chapter 4 (continued) Replace vbCrLf, vbCr, vbLf with constants in the ControlChars class ControlChars.NewLine Dim strMultilineMessage As String strMultilineMessage = “Line 1” & _ ControlChars.NewLine & “Line 2” Spring 2002

36 Chapter 4 (continued) Calling a procedure requires parentheses
VB 6 Way: ClearControls or Call ClearControls() VB .NET Way: [Call] ClearControls() Calling an event procedure requires two arguments Private Sub btnExit_Click(ByVal sender _ As System.Object, ByVal e _ As System.EventArgs) Handles btnExit.Click Call the event procedure: [Call] btnExit_Click(sender, e) Spring 2002

37 Chapter 4 (continued) Debug.WriteLine (Replaces Debug.Print)
Debug.WriteLine(“I got this far”) Clear the Output Window: Right-click / Clear All New Autos window — shows current value of variables and objects within approx. 6 statements Immediate window only valid at run time Keyboard shortcut for Step Into — F11 Spring 2002

38 Chapter 5 — Menus, Sub Procedures, and Sub Functions Topics Covered

39 Chapter 5 — Changes Create a menu by adding a MainMenu control to the component tray Great new Menu Designer replaces the Menu Editor Spring 2002

40 Chapter 5 (continued) For Context menus, add a ContextMenu control
A ContextMenu uses the same Menu Designer as a MainMenu Attach a context menu by setting the ContextMenu property of a control or the form Spring 2002

41 Chapter 5 (continued) New ColorDialog and FontDialog controls
Added to the component tray Use the control’s Show method to display Can set and retrieve properties of the control With dlgColor .Color = frmMain.BackColor .ShowDialog() .frmMain.BackColor = .Color End With Spring 2002

42 Chapter 5 (continued) The FontDialog control With dlgFont
'Change the font for the total label With dlgFont .Font = lblTotal.Font .ShowDialog() lblTotal.Font = .Font End With Spring 2002

43 Chapter 5 (continued) Arguments are passed ByVal (by default)
The Editor adds ByVal if you leave it out New Return statement Can still set function name to value Better to use the Return statement Private Function CalculateSum( _ ByVal intNum1 As Integer, _ ByVal intNum2 As Integer) As Integer 'Calculate the sum of the numbers Return intNum1 + intNum2 End Function Spring 2002

44 Chapter 6 — OOP Topics Covered
Object-oriented terminology Multitier applications Class vs. Object Visibility — Public, Private, Protected Constructors Instantiation Inheritance Spring 2002

45 Chapter 6 — Changes Namespaces Organize class libraries
Provide unique naming region Can create your own namespace Specifying namespaces lblMessage.Font = New System.Drawing.Font( _ "Arial", 12) or Imports System.Drawing.Font ... lblMessage.Font = New Font("Arial", 12) Spring 2002

46 Chapter 6 (continued) Classes vs. Objects
Use New keyword to instantiate For exception handling, declare the name at the module level and instantiate in a Try/Catch block Encapsulation Classes hide implementation details Only the Public properties and methods can be seen by other classes Spring 2002

47 Chapter 6 (continued) Inheritance New class based on existing class
Spring 2002

48 Chapter 6 (continued) Inheritance (continued)
All public properties and methods are inherited Visual inheritance — can inherit a form New keywords to support inheritance Inherits Overrides Overridable Public Class StudentBookSale Inherits BookSale Spring 2002

49 Chapter 6 (continued) Inheritance (continued) In base class
Public Overridable Function _ ExtendedPrice() As Decimal In derived class Overrides Function ExtendedPrice() _ As Decimal Spring 2002

50 Chapter 6 (continued) Polymorphism
Consistent naming, so that many classes can have the identically-named methods that perform an action appropriate for the object Example: The Add method for collections, lists, arrays, database Identically named methods in a class, with different implementations based on the arguments Keyword: Overloads Example: MessageBox.Show method, which has many different argument lists (signatures) Spring 2002

51 Chapter 6 (continued) New Format for Property Procedures
Private mstrLastName As String Public Property LastName As String Get LastName = mstrLastName End Get Set (ByVal Value As String) mstrLastName = Value End Set End Property Spring 2002

52 Chapter 6 (continued) ReadOnly and WriteOnly keywords for properties
Private mdecTotalPay As Decimal ReadOnly Property SalesTotal() As Decimal Get TotalPay = mdecTotalPay End Get End Property Spring 2002

53 Chapter 6 (continued) Shared members — one variable for for all instances of the class Often used for totals and counts 'SalesTotal property Private Shared mdecSalesTotal As Decimal 'SalesCount property Private Shared mintSalesCount As Integer Spring 2002

54 Chapter 6 (continued) Constructors — New() method
Replaces ClassInitialize procedure Constructors are not inherited Must write your own New() procedure First statement should be MyBase.New() Constructors can be overloaded Parameterized Constructors mBookSale = New BookSale(txtTitle.Text, _ CInt(txtQuantity.Text), _ CDec(txtPrice.Text)) Spring 2002

55 Chapter 6 (continued) Visibility Private Public Protected

58 Chapter 7 (continued) lstSchools.Items.Add("Harvard")
cboMajors.Items.Insert(1, cboMajors.Text) intTotalItems = lstItem.Items.Count strSelectedFlavor = _ lstFlavor.Items(lstFlavor.SelectedIndex) cboCoffee.Items.RemoveAt( _ cboCoffee.SelectedIndex) cboCoffee.Items.Remove(cboCoffee.Text) Spring 2002

59 Chapter 7 (continued) New events SelectedIndexChanged
Event to use when the user makes a selection Click event no longer supported for lists TextChanged One event for each keystroke Enter and Leave replace GotFocus and LostFocus events FindString and FindStringExact methods Not covered in this text SelectAll method For text boxes or text portion of a combo box Spring 2002

60 Chapter 7 (continued) Printing is completely changed
No more Printer.Print, Form.Print, PictureBox.Print All text printing is performed with a DrawString method on a Graphics object Add a PrintDocument control to the component tray Write all printing logic in the control’s PrintPage event procedure The control fires the event once for each page to print The program responds in the PrintPage event procedure Spring 2002

61 Chapter 7 (continued) Begin a printing operation:
Private Sub btnPrint_Click(ByVal _ sender As System.Object, ByVal _ e As System.EventArgs) _ Handles btnPrint.Click 'Print output on the printer 'Start the print process prtDocument.Print() End Sub Spring 2002

62 Chapter 7 (continued) Set up print page in the control’s PrintPage event: Private Sub prtDocument_PrintPage( _ ByVal sender As Object, ByVal e As _ System.Drawing.Printing.PrintPageEventArgs)_ Handles prtDocument.PrintPage 'Set up actual output to print End Sub Spring 2002

63 Chapter 7 (continued) Use the DrawString method in the control’s PrintPage event: 'Declarations at the top of the procedure Dim fntPrintFont As New Font("Arial", 12) 'More declarations here 'Print a line e.Graphics.DrawString(strPrintLine, _ fntPrintFont, Brushes.Black, _ sngPrintX, sngPrintY) Spring 2002

64 Chapter 7 (continued) Graphics objects
Must define fonts and brushes to create text Set up print lines with the DrawString method Print Preview Add a PrintPreviewDialog control to the form Assign the PrintDocument control to the PrintPreviewDialog’s Document property The same PrintPage event procedure is used to set up the print output ppdPrintPreview.Document = prtDocument ppdPrintPreview.ShowDialog() Spring 2002

65 Chapter 7 (continued) The Good News:
Do Loops and For / Next Loops are unchanged Spring 2002

66 Chapter 8 — Arrays Topics Covered
Select Case structure Shared events Arrays Structures Table lookup Combining list controls and arrays Multi-dimensional arrays Spring 2002

67 Chapter 8 — Changes Shared events (no control arrays)

68 Chapter 8 (continued) In shared event procedure:
'Save the name of the selected button Dim radSelected As RadioButton radSelected = CType(sender, RadioButton) Select Case radSelected.Name Case "radBlue" mcolorNew = Color.Blue Case "radBlack" mcolorNew = Color.Black Case "radRed" '… rest of code End Select Spring 2002

69 Chapter 8 (continued) All arrays are zero based
No Dim Array(LowerBound To UpperBound) Declare upper subscript unless initializing values at declaration Dim mstrProduct(99) As String Dim mintValue() As Integer _ = {1, 5, 12, 18, 20} Spring 2002

79 Chapter 10 (continued) Use the Server Explorer Manage connections
View table structure Drag tables and/or fields to the form to set up connection and data adapter Spring 2002

80 Chapter 10 (continued) A Configure Data Adapter wizard steps through creating the dataset The dataset can be based on an SQL Select statement or a stored procedure The wizard presents a Query Builder for building SQL Select statements Similar to the Query Designer in Access Creates the Select statement Can also generate the Insert, Delete, and Update SQL statements for updating the dataset You can preview the data from the file Spring 2002

81 Chapter 10 (continued) Bind the data to individual controls with the DataBindings properties At Form_Load or Page_Load call the Fill method to generate the dataset DataAdapterName.Fill(DataSetName) Dataset is disconnected Windows Forms — Bound controls are filled automatically Web Forms — Must execute the BindData method Bound controls are filled when BindData executes Web Forms are static — Only current record is transferred Spring 2002

82 Chapter 10 (continued) All new Datagrid controls
One for Windows forms; another for Web forms Navigation requires code No MoveNext, MovePrevious methods Me.BindingContext(DsBooks1, “Books”).Position += 1 Microsoft recommends one dataset per table Save changes back to the original data source by executing the dataset’s Update method The automatically-generated SQL statements execute for any changed rows Insert, Delete, Update Spring 2002
