Documenting your scripts is always a very good idea After all, the script makes perfect sense now, but will you be able to figure out what it's doing a year, or even a couple of months, from now For example, examine the script in Listing 32 See if you can figure out what the various portions of the script are doing Listing 32 AddUsersFromXLSvbs This script auto-creates users from an Excel spreadsheet

Review
In this chapter, I tried to illustrate some of the different components of a good script You've seen what functions, statements, and subroutines look like, how a main script ties them all together, and how comments and documentation make them easier to read and maintain in the future Keep all these new concepts in mind as you move through the rest of the book Try to spot intrinsic functions and custom ones, and watch for comment lines and other types of code documentation Try to use these standards in your own scripts, and you'll find yourself becoming more efficient and more capable very quickly COMING UP You're almost ready to start learning VBScript, but you need to learn how to design your scripts first In the next chapter, I'll show you my simple methodology for designing scripts that will let you write powerful administrative scripts without becoming a career programmer < Day Day Up >

4 Designing a Script
IN THIS CHAPTER Believe it or not, the toughest part about scripting isn't the language or programming objects or anything technology related It's in how you design your scripts and get them to do what you want I'll share tips and techniques that'll make scripting easier and more approachable Suppose you want to do a tune-up on your car, and you don't want to hire a mechanic to do the job for you It's easy enough to run down to the hardware store and acquire the necessary tools, and you can even buy some books that explain how to use those tools If you're like me, though, none of that will help you get the tune-up done Where do you start What should it look like Which tools do you use, and when I've found that's how many administrators feel about scripting Sure, the VBScript documentation is available, and there are plenty of examples on the Web But where do you start when it comes time to write your own scripts Much of this book will be focused on the tools, like VBScript and programming objects, that you'll need to do the job In this chapter, I want to share some of the tips and techniques that I use to actually get started in designing a new script It'll be easier to see how my design process works with a meaningful example Because login scripts are a popular administrative use of VBScript, I'll use a login script as an example I want to write a login script that maps three network drives based on the users' group membership, and then maps a printer based on the user's DHCP-assigned IP address That way, I can assign a printer that's local to wherever the user logged on I also want to display a welcome message, and I want the script to run on Windows NT Workstation 40 (Service Pack 6a or later), Windows XP Professional (Service Pack 1 or later), and Windows 2000 Professional (Service Pack 3 or later) < Day Day Up >
