Developing Web Applications

Avoiding Common Mistakes

Studies show that developers tend to make the same types of mistakes no matter what programming language they are using. Rather than spending a lot of time tracking down bugs, it is always easier to avoid creating them in the first place. Here are some common scripting mistakes that lead to bugs, as well as ways to avoid them:

• Misspelling Variables
• Using an Object or Variable Out of Scope
• Not Using the Web Server to View ASP Pages
• Using the Scripting Language Inefficiently
• Mixing Data Types
• Misusing the Equal Sign
• Using Procedures Incorrectly
• Not Handling Errors
• Making Off-by-One Errors with Collections
• Forgetting Ending Braces, Delimiters, and Statements
