APPENDIX B HOW TO HOW TO: INSTALL, INVOKE, AND EXIT VISUAL BASIC A. Install the Working Model Edition of Visual Basic 1. Place the CD accompanying this book into your CD drive. 2. Wait about five seconds. You will most likely hear a whirring sound from the CD drive and then a large window with the words “Visual Basic 6.0 Working Model” will appear. If so, go to Step 5. 3. If nothing happens automatically after Step 1, double-click on My Computer in the Windows Desktop. 4. A window showing the different disk drives will appear. Double-click on the icon containing a picture of a CD (along with a drive) and having the drive letter below the label. A large window with the words “Visual Basic 6.0 Working Model” will appear. 5. The title bar of the large window says “Installation Wizard for Visual Basic 6.0 Working Model.” The installation wizard will guide you through the installation process. Click on Next to continue. 6. An End User License Agreement will appear. After reading the agreement, click on the the circle to the left of the sentence “I accept the agreement.” and then click on Next. 7. The next window to appear has spaces for an ID number, your name, and your company’s name. Ignore the ID number. Just type in your name and, optionally, a company name, and then click Next. 8. Visual Basic 6.0 requires that you have Internet Explorer 4.0 or later version on your computer. If a recent version is not present, the Installation Wizard will install it for you. If so, successive windows will guide you through the installation. At some point you will be required to restart your computer. We recommend doing the standard installation and using the recommended destination folder. 9. You will next be guided through the installation of DCOM98, which is also needed to Visual Basic 6.0. After installing DCOM98, the installation wizard will automatically restart your computer and then continue with the installation of VB6.0. Note: If another widow is covering the Installation Wizard window, then click on the Installation Wizard window. If you can’t find the Installation Wizard window, repeat Steps 1–5. You will now be guided through the installation of the Working Model Edition VB6.0. At the end of the installation, Visual Basic will be invoked. 10. The next window requests the name of the Common Install Folder. We recommend that you simply click on Next, which will accept the default folder and copy some files into it. 11. The next window to appear is the Visual Basic 6.0 Working Model Setup. Click on Continue. 12. The next screen shows your Product ID number. Enter your name and then click on OK. Appendix B 409
