捕获代码时出错 [英] Error trapping code
问题描述
我广泛使用代码;我可能过度使用了它。但是我一直在使用
错误捕获错误，现在我被困在那里。
一个适用于我的表格我正在使用的系统，显然会在实际使用它的系统上遇到问题，而且由于我使用了很少的错误捕获，所以它很难消失非常好。
我当然会尝试修复导致错误的任何内容并添加
错误捕获到问题所在的函数，但是我
意识到我需要添加一个更宽松的错误捕获代码
手。
因此，我的问题应该是错误捕获代码书挡每个子
和函数？如果没有，我用什么标准决定是否添加
？
- 谢谢，thelma
是的，如果应用程序很重要，请在应用程序中的每个sub和
函数中使用错误捕获。

错误陷阱，现在我已被困在那里了。
在我正在使用的系统上对我有用的表格，显然在实际使用它的系统上会遇到问题，因为我使用了很少的错误捕获它会非常不合理地死掉。
我当然会尝试修复导致错误的任何问题，并将错误捕获添加到问题所在的函数中，但是我意识到我需要添加错误捕获代码以及更自由的手。
因此，我的问题是，错误捕获代码是否应该为每个子和功能提供支持？如果没有，我用什么标准决定是否添加它？

函数，将值返回给调用过程的方法，don '
必然需要错误处理，但调用代码肯定应该是b $ b b。对象（类模块）应该捕获错误并将其传递给客户端代码
。

之后，有一种简单的方法可以将基本错误捕获插入到所有潜艇中吗？只是基本的：msgbox err.number&错误的描述内容

I use code extensively; I probably overuse it. But I''ve been using
error trapping very sparingly, and now I''ve been trapped by that.
A form that works for me on the system I''m using, apparently runs into
problems on the system where it will actually be used, and since I
used so little error-trapping it dies very ungracefully.
I will of course try to fix whatever is causing the error and add
error-trapping to the functions where the problem surfaces, but I
realize that I need to add error-trapping code with a more liberal
hand.
My question is, therefore, should error-trapping code bookend every sub
and function? If not, what criteria do I use to decide whether to add
it or not?
--thanks, thelma
解决方案Yes, if the application matters, use error-trapping in every sub and
function in your application.

Functions, methods that return a value to a calling procedure, don''t
necessarily need error handling, but the calling code certainly should
have it. Objects(class modules) should trap an error and pass it on to
the client code.
Is there an easy way to insert basic error trapping into all subs after the
fact? Just the basic : msgbox err.number & err.description stuff
