Using the Code Samples and CD

Using the Code Samples and CD

Throughout the text, we refer to code samples both in the book and on the companion CD. To get the most out of this book, make sure you try these samples out for yourself. To do this, we recommend that you use a computer with the following system configuration:

• Pentium III, 500 MHz or faster

• 256 MB of RAM or more

• CD-ROM or DVD drive

• Microsoft Windows NT 4, Windows 2000, or Windows XP

• Microsoft Visual Basic 6, with Service Pack 5 or later

• Microsoft Visual Basic .NET (Professional or Enterprise edition), or Visual Studio .NET. We recommend that you not use the standard edition of Visual Basic .NET, since it doesn t include the Upgrade Wizard.

Notice that we recommend installing both Visual Basic 6 Service Pack 5 and Visual Basic .NET on the same machine. This is actually a requirement for many upgrades, since the Upgrade Wizard needs to refer to your project s COM controls and type libraries during the upgrade. The simple rule of thumb is to make sure the program works in Visual Basic 6 on the same machine before upgrading.

This book presents before-and-after code samples in Visual Basic 6 and Visual Basic .NET. To help you tell the difference, they are formatted differently. Visual Basic 6 samples are in normal type:

MsgBox "Hello from Visual Basic 6"

Visual Basic .NET samples are in boldface type:

MsgBox "Hello from Visual Basic .NET"

The CD that accompanies the book also contains a searchable, electronic version of the text. Copy the e-book to your hard drive, and you ll have a complete upgrade guide at your fingertips.
