Sounds like a VFP web Service might be the way. You would compile your code into a vfp mtdll, have an iis web site at your local site or at an ISP that runs the vfp mtdll, and the client web site would use their existing scripting language to access the web service method that does the calculation. You'd need vfp 7 or above for this...

>My client is running an insurance sales website which invites users to complete a form which is then submitted, a premium calculated, and (hopefully) a sale made via a credit-card transaction. Up to now the premium calculation has been very straightforward (ie. a flat-rate monthly or annual fee), but the formula needs to be modified to take into account weighting factors such as age, health history, postcode, etc.. There is already a VFP function which takes these parameters and produces the required premium via. a complex set of remote views, but it is fast, and it works.

>The question is, how can this function be called by the site and return a number of values, which could be in the form of properties of a single object or values in a single row of a cursor (eg. monthly premium, annual premium, underwriter commission, product expiry date, etc.)? I have visions of a self-contained .exe or COM object that can take the parameters and return the results in the form of a comma-delimited string to a file (perhaps as a .csv file, where the first line can have field descriptors) which can then be accessed by the scripting language (or maybe a stored procedure) and the required data extracted. Is this possible? Is there an easier solution? - I bet there is.
