字符串出现次数 [英] String occurence count

问题描述

你好，


我需要一个函数来返回另一个中已定义字符串的出现次数;

即如果搜索字符串是''预订''和主要字符串''康沃尔 - 预订，德文 - 预订，威尔斯预订''然后该功能应返回数值3.

是否有内置功能实现这个？


非常感谢提前

解决方案

我知道没有内置功能可以做到这一点但是以下应该涵盖它。我没有测试过这个，所以请告诉我是否有任何错误。

展开 | 选择 | Wrap | 行号

嗯。给出了一个无效的程序错误，并且pos变量永远不会超过1！

你能否确认这是代码停止的行...

Hello,

I need a function to return the number of occurences of a defined string within another;
ie if the search string is ''booked'' and the main string is ''Cornwall - booked, devon - booked, wales booked'' then the function should return the numeric value of 3.
Is there a built-in function to achieve this?

Many thanks in advance

解决方案

There is no built in feature that I know of to do this but the following should cover it. I haven''t tested this so let me know if there are any errors.

Expand|Select|Wrap|Line Numbers

Hmmm. gives an invalid procedure error and the pos variable never goes above 1!

Can you confirm this is the line the code is stopping at ...
