\par }\pard \sb120
\par \pard \sb120 The release of Visual Basic
3.0 coincides with the release of the third printing of this book. It won't surprise you to know that this printing has been revised for the new release of VB. However, since the book is essentially a Windows SDK for Visual Basic programmers, the chang
es for version 3.0 were quite minor (this would not be the case had we been dealing with a major release of Windows).
\par \pard \sb120 In fact, the changes are so minor that it makes no sense for you to go out and buy a new copy of the book. Instead, as a public service a
nd for the sake of good customer relations, this file contains a list of all of the changes and corrections that were incorporated into the third printing.
\par \pard \sb120
This file is based on the corrections as submitted to the publisher. I can't guarantee that they match the 3rd printing exactly (they will be proofing the text for grammer and spelling), but it should be close enough. On the other hand, because of lead t
imes in the publication process, this document contains corrections that are not present in the 3rd
printing (those corrections will also appear in the readme.txt file on the disk that comes with the second printing - so there is no need to pass this document on to people who have the 3rd printing).
\par \pard \sb120 This file may be distributed freely - please pass it around, post it on other BBS systems, etc.
\par \pard \sb120 Thanks to all of you who spotted errors in the book and forwarded them to me. Unfortunately, I did not keep track of who submitted suggestions and corrections, but off the top of my head I do remember Jonathan Zu
ck, Keith Pleas and Ted Young. To the others - I apologize for my forgetfulness (feel free to drop me a note and I'll be sure to mention you in the next set of changes).
\par \pard \sb120
Also, allow me to take this moment to encourage you to take a look at the SpyWorks-VB and CCF-Cursors demo program that comes on the book's disk. SpyWorks-VB is especially useful in conjunction with the book when it comes to taking advantage of advanced
Windows API techniques.
\par \pard \sb120

\par \pard\plain \s2\li360\sb120 \f5\fs20\lang1033 \tab
The orginal printing of this book was released for version 2.0 of Visual Basic. This edition has been revised as needed to be compatible with both Visual Basic 2.0 and Visual Basic 3.0. The changes were quite minor, owing to the fact that while Visual Ba
sic changed, the underlying Windows API has not. All of the sample files and listings have been tested with Visual Basic 3.0, however they are still presented in version 2.0 format in order to ensure compatibility with both versions.
\par \pard \s2\li360\sb120 \tab Some discussion of Visual Basic 1.0 has been left in this revision where appropriate. The listing for the RectPlay example in chapter 4 discusses how to interpret listings for version 1.0 if necessary.

\par }\pard \s2\li360\sb120 Subclassing is a technique which allows you to intercept Windows messages going to a form. This technique can be used to detect the WM_COMMAND Windo
ws message directly, eliminating the need to ensure compatibility with a Visual Basic menu structure when using menu API functions. It also allows you to intercept the WM_SYSCOMMAND message which makes it practical to customize an application's system men
u. Refer to the Message Handling section in chapter 17 for more information on subclassing and the tools required to use this powerful technique.

\par \pard \sb120 In each of these cases, the first line says: "Identifier of the menu entry to check or unch

\par \pard \sb120 {\b\ul GetObject}{\b
\par }\pard \sb120 Visual Basic 3.0 uses {\b GetObject} as a reserved word. In order to
accomodate this, the declaration for GetObject has been changed to GetObjectAPI which is aliased to GetObject. The new declaration of GetObject as seen in file apidecs.txt, apidecs.bas and in Appendix E page 933 is:
\par \pard \sb120 Declare Function GetObjectAPI% Lib "GDI" Alias "GetObject" (ByVal hObject%, ByVal nCount%, ByVal lpObject&)
\par \pard \sb120 The command {\b GetObject} must be changed to {\b GetObjectAPI} in the following files:
