错误捕捉:
例子一:
On Error Resume Next ‘如果遇到错误,不管错误,继续往下执行,但如果嵌套了其他错误处理语句,这些错误处理语句还是会按照自己规则运行
语句xxxx
On Error GoTo 0 ’结束错误捕捉
例子二:
Sub 例子过程()
On Error GoTo Err_Handle ‘之后语句出错则跳转至 Err_Handle 标签处
处理语句1 ‘若出错,则跳转到 Err_Handle
On Error GoTo 0 ‘跳出错误捕捉,之后语句若出错,自动弹出出错框
处理语句2 ‘若出错则弹出错误,可调试或结束
Exit Sub ‘如果没有这个退出过程语句,会一直执行下去
Err_Handle:
MsgBox ("不存在该数字")
End Sub
