On encountering a run-time error, an On Error statement enables or disables an error-handling routine within a procedure. A Resume statement can only be used in an error-handling vba error routine - it resumes execution at a sepcified point after the error-handline routine finishes. You can get information on the error from the properties of the Error object - this object is the Err Object. In this section, we cover: VBA Erros & Error Handling In vba programming you can have Syntax Errors or Run-time Errors. An error handler determines what action is to be taken within a procedure, on vba error handling the occurrence of a run-time error. A syntax error occurs when you enter a line of code which is not allowed or recognized by Visual Basic. You will encounter a syntax error on misspelling a keyword or a named argument, for incorrect punctuation (ex. not specifying a comma as a placeholder for the omitted argument), use an undefined procedure, and so on. These errors are easier to locate as the Code Editor points them out at the time you are writing your code. A run-time error occurs at the time during which your code is running, that is after you have created your macro. There could be an error in your programming due to incorrect logic used in your code that prevents it from doing what you intended and may stop code execution, for example, if your code attempts to divide a value by zero. Another reason for an error which may cause even a valid code to crash could be a condition not being met, say, a reference to a worksheet in your code which has been deleted by the user. Other examples when a run-time error can occur are: on using incorrect variable names or variable types; if your code goes into an infinite loop; using a value or reference outside the allowable range; and s
Error and Resume statements Finding how you can use an error to your advantage When working with VBA, you should be aware of two broad classes of errors: programming errors and run-time errors. (I cover programming errors, also known as bugs, in the next chapter.) A well-written program handles errors the way Fred Astaire danced: gracefully. Fortunately, VBA includes several tools to help you identify errors — and then handle them gracefully. Types of Errors If you've tried any of the examples in this topic, you have probably encountered one or more error messages. Some of these errors result from bad VBA code. For example, you may spell a keyword incorrectly or type a statement with the wrong syntax. If you make such an error, you won't even be able to execute the procedure until you correct it. This chapter does not deal with those types of errors. Instead, I discuss runtime errors — the errors that occur while Excel executes your VBA code. More specifically, this chapter covers the following: Identifying errors Doing something about the errors that occur Recovering from errors Creating intentional errors (Yes, sometimes an error can be a good thing.) The ultimate goal of error handling is to write code that avoids displaying Excel's error messages as much as possible. In other words, you want to anticipate potential errors and deal with them before Excel has a chance to rear its ugly head with a (usually) less-than-informative error message. An Erroneous Example To get things started, I developed a short VBA macro. Activate the VBE, insert a module, and enter the following code: As shown in Figure 12-1, this procedure asks the user for a value. It then enters the square root of that value into the active cell. Figure 12-1: The InputBox function displays a dialog box that asks the user for a v
