Error Types (Visual Basic) Visual Studio 2015 Other Versions Visual Studio 2013 Visual Studio 2012 Visual Studio 2010 Visual Studio 2008 Visual Studio 2005 Visual Studio .NET 2003 In Visual Basic, errors (also called exceptions) fall into one of three categories:
Error C#
syntax errors, run-time errors, and logic errors.Syntax ErrorsSyntax errors are those that appear while you write code. Visual Basic checks your code as you type it in the Code Editor window and alerts you if you make a mistake, such as misspelling a word or using a language element improperly. Syntax errors are the most common type of errors. You can fix them easily in the coding environment as soon as they occur.Note The Option Explicit statement is one means of avoiding syntax errors. It forces you to declare, in advance, all the variables to be used in the application. Therefore, when those variables are used in the code, any typographic errors are caught immediately and can be fixed.Run-Time ErrorsRun-time errors are those that appear only after you compile and run your code. These involve code that may appear to be correct in that it has no syntax errors, but that will not execute. For example, you might correctly write a line of code to open a file. But if the file is corrupted, the application cannot carry out the Open function, and it stops running. You can fix most run-time errors by rewriting the faulty code, and then recompiling and rerunning it.Logic ErrorsLogic er

lifetime of your application. This seams to be an avoidable fact of life. The errors your program will encounter can be classified in three categories: runtime, syntax, and logic errors. Application: Introducing Errors Start Microsoft Visual Studio To create a new application, on the main menu, click File -> New Project... In the middle list, click Console Application Change the Name to WattsALoan1 Click OK On the main menu, click Project -> WattsALoan1 Properties Click the arrow of the Application Type box and select Windows Forms Application In the Solution Explorer, right-click Module1.vb and click Rename Type LoanEvaluation.vb and press Enter twice Change the document as follows: Module LoanEvaluation Public Function Main() As Integer Return 0 End Function End Module Syntax Errors A syntax error is due to a misuse of the Visual Basic language in your code. For example, the Visual Basic language has a set of keywords that you should (must) not use to name your variable. This rule is usually easy to respect if you are using a professional text editor such as the Code Editor of Microsoft Visual Basic. The Code Editor of Microsoft Visual Basic makes it easy to be aware of syntax errors as soon as they occur: When you start typing code, the IntelliSense starts building a list of words that match the first characters and those that include the characters already typed: If you see a word you need and it is highlighted, you can press Enter to select it. You can also double-click the word from the list. If the list is long and the word does not appear yet, you can keep typing (adding characters) until the word you want comes up If you mistype a word or a keyword, the Code Editor would indicate the error by underlining the word. If you place the mouse on it, a message would display the reason for the error: If you declare a variable, or once you have declared a variable, whenever you want to use it, as soon as you start typing its name, the IntelliSense would display a list thatincludes that variable The Visual Basic language is equipped with many operators and each operator has rules. If you misuse an operator, the section of your code would be underlined. You can position the mouse on it to see the resulting error message: As you can see, if you create your application in Microsoft Visual Studio, the Code Editor is fully eq
