Hello All,
Has anyone on these forums ever written an Expression Parser and probably more to the point a simple expression parser.
I'm reasonably competent in VB6 and am now starting a project in VB.NET where I would like to have the ability for the users to define their own expressions/functions.
If I'm not describing this very well it's like the formula you can put into Excel.
My requirement is for both Math and String functions and I'm happy to code the individual functions but I'm not sure how to write the expression parser or where to start.
I've searched the web and really have conflicting examples so failing anyone doing it themselves can anyone point me at some useful info. they have.
Thanks & regards,
Brian
