In this video tutorial you will learn about debugging your application. At some point, most applications contain bugs (errors) that prevent the application from operating properly. In general, there are two types of errors: compile errors and runtime errors. Compile errors are syntax errors, such as misspelled keywords or the incorrect use of operators or punctuation. Visual Basic checks each line of code for compile errors as soon as you enter it. When a compile error is found, it is underlined with a jagged blue line. A description of the error is also displayed in the Error List window. You display it by clicking VIEW on the menu bar, and then selecting Error List.
