DLL Parameters

[prustie]

Hi

I am trying to use a Post Code look up application using a DLL.

I have managed to get the functions declared correctly and the data file opened.

However when I try to match a Post Code the function is returning an internal error and so unfortunately is the error function.

I think that it is down to one of the parameters which is defined in the documentation as:

char hits If >0 hits are found during the search, will contain a string representation (decimal) of the number of hits (suitable for conversion via atoi()). Cannot be NULL. Should point to an array of at least 8 characters.

Can anyone tell me how I define this parameter?

Thanks

Malcolm,
From VFP, I'd try:
DECLARE mydll ..., string @, ...

lcHits = Space(10)
=mydll(..., @lcHits, ...)
