Custom Functions in Crystal Reports 8.5?

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.

W开发者_如何转开发as there not a way to do this?

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.

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. :)

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?
