at the time the application is being used. Some other problems could be caused by the computer on which the application is being used. While developing your application, you should anticipate http://www.functionx.com/visualbasic/exceptions/errorhandling.htm as many problems as possible as take appropriate actions. Error Categories There are three main types of errors that could occur while your application is being used: Syntax Errors: A syntax error comes from your mistyping a word or forming a bad expression in your code. It could be that you misspelled a keyword such as ByVel instead of ByVal. It could also be a bad expression. Examples are: 524+ error handling + 62.55 if Number == 2 Number = 6 If you use the Microsoft Visual Basic IDE to write your code, it would point out the errors while you are writing your code, giving up time to fix them. There are other syntax errors that the IDE may not detect. This could come from using a data type or class that doesn't exist. When you compile your application, the compiler can error handling vb let you know about other syntax errors. Those types of errors are those the compiler cannot execute. It this case, the compiler intercepts, stops, and lets you know. For this reason, syntax errors are almost the easiest to fix. Most of the time, the compiler would point out where the problem is so you can fix it. Run-Time Errors: After all syntax errors have been fixed, the program may be ready for the user. The time period a person is using an application is called run-time. There are different types of problems that a user may face when interacting with your program. For example, imagine that, in your code, you indicate that a picture would be loaded and displayed to the user but you forget to ship the picture or the directory of the picture indicated in your code becomes different when a user opens your application. In this case, when you compiled and executed the application in your machine, everything was fine. This is a type of run-time error. Run-time errors are mostly easy to fix because you will know what the problem is occurring and why. Logic Errors: These are errors that don't fit in any of the above categories. They could be caused by the user misusing your applicatio
