It comes with various option: On Error Goto label Once your code encounters this statement, it will jump to label: if an error occurs. It is useful if you need to do some error handling - especially if there are multiple places where things can go wrong but they always result in the same "need to fix something" routine. You can use Err.Number or Err.Description to find out what caused the error. On Error Resume Next Is useful when you have a single line that might cause an error - but if it does you want to ignore and keep going. This is most likely the right thing to do here. Don't forget to put On Error Goto 0 After you have passed the "danger", otherwise your code will (wit

Some of the results are "#N/A" and there will be a green triangle on the left top of the cell. I want to remove the green triangle (ignore the error) automatically, but the "#N/A" result should be vba on error remained, just remove the green triangle. Anyone knows how to do this? Thanks in advance. excel vba share|improve this question asked Mar 5 '14 at 9:08 user2774993 2717 add a comment| 4 Answers 4 active oldest votes up vote 1 down vote If you want the green triangle to go away you need to set the Error.Ignore property to true. For example, if you have a formula such as "=1/0" in cell A1, then in VBA you could do something like this: Dim r as Range Set r = Range("A1") r.Errors.Item(1).Ignore = True And the green triangle will go away. share|improve this answer answered Mar 5 '14 at 9:28 steveo40 781410 Thanks for your reply! I tried your method, but returned "Application not-defined" error...@steveo40 –user2774993 Mar 5 '14 at 9:38 If you copy the code exactly into a new sub and pop the dodgy formula into cell A1 it should work fine.

and the condition. Description: ignore-errors is used to prevent conditions of type error from causing entry into the debugger. Specifically, ignore-errors executes forms in a dynamic environment where a handler for conditions of type error has been established; if invoked, it handles such conditions by returning two values, nil and the condition that was signaled, from the ignore-errors form. If a normal return from the forms occurs, any values returned are returned by ignore-errors. Examples: (defun load-init-file (program) (let ((win nil)) (ignore-errors ;if this fails, don't enter debugger (load (merge-pathnames (make-pathname :name program :type :lisp) (user-homedir-pathname))) (setq win t)) (unless win (format t "~&Init file failed to load.~%")) win)) (load-init-file "no-such-program") >> Init file failed to load. NIL Affected By: None. Exceptional Situations: None. See Also: handler-case, Section 9.1 (Condition System Concepts) Notes: (ignore-errors . forms) is equivalent to: (handler-case (progn . forms) (error (condition) (values nil condition))) Because the second return value is a condition in the exceptional case, it is common (but not required) to arrange for the second return value in the normal case to be missing or nil so that the two situations can be distinguished.
