- If your error-handling routine corrected the error, returning to the line that generated the error might be the appropriate action.
- We keep our error code simple for now.
But, after all I agree with you :) –KazimierzJawor Mar 20 '13 at 18:35 Try-Catch-Finally wouldn't have been asking too much within VBA ! –whytheq Mar 21 '13 at It displays information about the error and exits the procedure. A solution that works for me to better handle complex iterations is separating setting of objects in their own functions, e.g. On Error Exit Sub The error hander is still active when the second error occurs, and therefore the second error is not trapped by the On Error statement.
If a run-time error occurs, control branches to the specified line, making the error handler active. Vba On Error Goto 0 In order to support the raising of exceptions of derived exception types, a Throw statement is supported in the language. Errors in general come in three flavors: compiler errors such as undeclared variables that prevent your code from compiling; user data entry error such as a user entering a negative value http://www.cpearson.com/excel/errorhandling.htm The same program as Square Root 1 but replace 'On Error Resume Next' with: On Error GoTo InvalidValue: Note: InvalidValue is randomly chosen here, you can use any name.
If you omit the ‘Exit Sub' statement then the Error handler code block will always execute even if no exception is encountered. On Error Goto 0 Share it with others Like this thread? We display a MsgBox with some text and the address of the cell where the error occurred. How can I guarantee that one set of error trapping has been "closed off" before the code moves on - does On Error Goto 0 reset the error trapping?

For instance: For example I have a simple macro as follows: Sub GetErr() On Error Resume Next N = 1 / 0 ' Line causing divide by zero exception For i But some people frown on this almost as much.

Easy enough to correct by setting the wb to Nothing before the next iteration. The line argument is any line label or line number.

During the development stage, this basic handler can be helpful (or not; see Tip #3).
