It makes the code much more readable and is a new standard for VB programmers that is consistent with the standard that nearly all other languages adopted long ago. 153_VBnet_TOC 8/16/01 1:12 PM Page xvii xviii Contents Chapter 5 .NET Programming Fundamentals 171 Introduction 172 Variables 173 Constants 175 Structures 176 Program Flow Control 178 If…Then…Else 178 Select Case 182 While Loops 184 For Loops 186 Arrays 187 Declaring an Array 188 Multidimensional Arrays 189 Dynamic Arrays 191 Functions 192 Object Oriented Programming 196 Inheritance 196 Polymorphism 197 Encapsulation 197 Classes 198 Adding Properties 198 Adding Methods 200 System.Object 201 Constructors 201 Overloading 202 Overriding 203 Shared Members 205 String Handling 206 Error Handling 210 Summary 213 Solutions Fast Track 214 Frequently Asked Questions 217 NOTE When porting Visual Basic applications to Visual Basic .NET, be careful of the lower bounds of arrays. If you are using a for loop to iterate through the array, and it is hard-coded to initialize the counter at 1, the first element will be skipped.

Collectionsare groups of like objects. Collections are similar to arrays, but they don’t have to be redimensioned. You can use the Addmethod to add objects to a collection. Collections take a little more code to create than arrays do, and sometimes accessing a collection can be a bit slower than an array, but they offer significant advantages because a collection is a group of objects whereby an array is a data type. 153_VBnet_TOC 8/16/01 1:12 PM Page xix xx Contents Displaying Modal Forms 288 Displaying Modeless Forms 289 Displaying Top-Most Forms 289 Changing the Borders of a Form 289 Resizing Forms 291 Setting Location of Forms 292 Form Events 294 Creating Multiple Document Interface Applications 297 Creating an MDI Parent Form 297 Creating MDI Child Forms 298 Exercise 7.1 Creating an MDI Child Form 298 Determining the Active MDI Child Form 299 Arranging MDI Child Forms 299 Adding Controls to Forms 300 Anchoring Controls on Forms 301 Docking Controls on Forms 303 Layering Objects on Forms 304 Positioning Controls on Forms 304 Dialog Boxes 305 Displaying Message Boxes 306 Common Dialog Boxes 306 The OpenFileDialog Control 306 The SaveFileDialog Control 309 The FontDialog Control 311 The ColorDialog Control 313 The PrintDialog Control 315 The PrintPreviewDialog Control 316 The PageSetupDialog Control 321 Creating Dialog Boxes 322 Creating and Working with Menus 323 Adding Menus to a Form 323 Exercise 7.2 Adding a Menu to a Form at Design Time 323 Creating Dialog Boxes 1.Create a form. 2.Set the BorderStyle property of the form to FixedDialog. 3.Set the ControlBox, MinimizeBox, and MaximizeBox properties of the form to False. 4.Customize the appearance of the form appropriately. 5.Customize event handlers in the Code window appropriately. 153_VBnet_TOC 8/16/01 1:12 PM Page xx Contents xxi Dynamically Creating Menus 326 Exercise 7.3 Adding a Menu to a Form at Design Time 326 Adding Status Bars to Forms 328 Adding Toolbars to Forms 330 Data Binding 332 Simple Data Binding 332 Complex Data Binding 333 Data Sources for Data Binding 333 Using the Data Form Wizard 334 Using the Windows Forms Class Viewer 338 Using the Windows Forms ActiveX Control Importer 338 Summary 340 Solutions Fast Track 340 Frequently Asked Questions 344 Chapter 8 Windows Forms Components and Controls 347 Introduction 348 Built-In Controls 348 Label Control 351 LinkLabel Control 354 TextBox Control 357 Button Control 361 CheckBox Control 364 RadioButton Control 365 RichTextBox Control 367 TreeView Control 369 ListBox Control 371 CheckedListBox Control 374 ListView Control 376 ComboBox Control 381 DomainUpDown Control 384 NumericUpDown Control 386 PictureBox Control 388 TrackBar Control 389 Adding Items to a Combo Box at Design-Time 1.Select the ComboBox control on the form. 2.If necessary, use the Viewmenu to open the Properties window. 3.In the Properties window, click the Itemsproperty, then click the ellipsis. 4.In String Collection Editor, type the first item, then press Enter. 5.Type the next items, pressing Enterafter each item. 6.Click OK. 153_VBnet_TOC 8/16/01 1:13 PM Page xxi xxii Contents DateTimePicker Control 391 Panel Control 394 GroupBox Control 396 TabControl Control 397 Creating Custom Windows Components 399 Exercise 8.1:Creating a Custom Windows Component 399 Creating Custom Windows Controls 403 Exercise 8.2:Creating a Custom Windows Control 404 Summary 407 Solutions Fast Track 407 Frequently Asked Questions 408 Chapter 9 Using ADO.NET 409 Introduction 410 Overview of XML 411 XML Documents 411 XSL 411 XDR 412 XPath 412 Understanding ADO.NET Architecture 412 Differences between ADO and ADO.NET 414 XML Support 414 ADO.NET Configuration 415 Remoting in ADO.NET 415 Maintaining State 415 Using the XML Schema Definition Tool 416 Connected Layer 417 DataProviders 418 Connection Strings 418 Exercise 9.1 Creating a Connection String 419 Command Objects 421 DataReader 425 DataSet 426 XML Documents XML documents are the heart of the XML standard.
