Crystal Reports 8.5 中的自定义函数？
我可以发誓有一种方法可以做到这一点（无需 DLL），但是浏览 google 的前几页，我找不到它。也许我在想别的事情。
我必须在 Crystal Reports 8.5 中进行一些开发。我认为有一种方法可以编写自定义函数。比如创建一个自定义公式，然后在公式代码中编写一个函数，并将公式字段放在报告的顶部，使其可供其他任何需要它的人使用。
难道就没有办法做到这一点吗？
I could've sworn there was a way to do this (without DLLs), but going through the first several pages of google, I can't find it. Maybe I'm thinking of something else.
I'm having to do some development in Crystal Reports 8.5. I thought there was a way to write custom functions. Something like creating a custom formula then writing a function in the code of the formula and putting the formula field at the top of your report, making it then available to anything else needing it.
Was there not a way to do this?

不确定 8.5，但我猜它会在公式编辑器中的某个地方，就像在 11.5 设计器中一样。报告自定义函数位于该树视图中存储库自定义函数的正上方。
Not sure about 8.5, but I'd guess it'd be somewhere in the formula editor like it is in 11.5 designer. Report Custom Functions is right above the Repository Custom Functions in that treeview.
也许您正在考虑我认为所谓的自定义功能存储库，我认为它只能与 Crystal Enterprise 一起使用。说实话，我对此没有任何经验，我只是想我会为你扔掉这个术语，让你可以查找一些东西。
另外，我知道您可以使用全局或共享变量在整个报告（子报告等）中共享公式值，但我不确定公式本身。
希望这有帮助。 :)
Maybe you are thinking of what I believe is called the Custom Function Repository, which I think can only be used with Crystal Enterprise. Truthfully I do not have any experience with it I just figured I'd throw out the term for you for something that you could look up.
Also, I know that you can share formula values across the report (to sub reports and such) with the use of global or shared variables, but I'm not sure about formulas themselves.
Hope this helps. :)
公式可以引用其他公式，从而允许您细分和重用工作，就像函数可以在编程语言中调用其他函数一样。你需要一些特别的东西吗？
Formulas can reference other formulas, allowing you to subdivide and reuse work, the same way that functions can call other functions in a programming language. Are you needing something special?
