Introduction Trapping Errors at Run-Time Building Error Handlers Raising Your Own vb6 runtime error -2147467259 Errors Summary Introduction The various functions, statements, properties and methods available in Visual Basic and the components used in Visual Basic expect to deal with certain types of data and behavior in your https://msdn.microsoft.com/en-us/library/5hsw66as.aspx applications. For example, the CDate() function can convert a value to a Date variable. The function is remarkably flexible in the type of information it can accept, but it expects to receive data that it can use to derive a date. If you provide input that it can't convert, it raises error number 13 - "Type mismatch" - essentially saying "I can't handle this input data." In http://www.vb6.us/tutorials/error-handling an application, this type of error may be a program logic error (you simply passed the wrong data) or it may be a data entry error on the part of the user (you asked for a date and the user typed a name). In the first case, you need to debug the program to fix the mistake. However, there is no way for you to anticipate the behavior of the end users of the application. If the user enters data you can't handle, you need to deal with the situation. Dealing with errors at run-time is a two step process: Trap the Error Before you can deal with an error, you need to know about it. You use VB's On Error statement to setup an error trap. Handle the Error Code in your error handler may correct an error, ignore it, inform the user of the problem, or deal with it in some other way. You can examine the properties of the Err object to determine the nature of the error. Once the error has been dealt with, you use the Resume statement to return control to the regular flow of the code in the application. In addition to dealin

EDIT: If I have output in an error-handler block that is showing an error number of 0, what does that indicate? vb6 error-handling share|improve this question edited Jun 22 '10 at 13:29 asked Jun 22 '10 at 5:31 CJ7 4,99232114220 add a comment| 3 Answers 3 active oldest votes on error goto up vote 3 down vote accepted No. The VB6 manual makes it clear that On Error Goto 0 only affects the current procedure: On Error Goto 0 disables any enabled error handler in the current procedure. EDIT There's now an addition to the question, which wasn't there when I posted this answer. The question is "If I have output in an error-handler block that is showing an error number of 0, what does that indicate?". For the answer, see Mike's answer. share|improve this answer edited Jun 22 '10 at 17:42 answered Jun 22 '10 at 9:12 MarkJ 24.9k34878 add a comment| Did you find this question interesting?

If so, control passes to that error handler. If no error handler is in effect, Visual Basic moves up the call stack to the calling routine to see if an error handler is currently installed there. If so, the system resumes execution at that error handler. If no e
