Hi Guillaume,

There's a bug in VFP6 that could cause this error. Try

lcClass = "Opendbf",
lcDll = "Opendll.dll")
... = newobject("Opendbf",lcClass, lcDll)

>Thanks Sergey, but when I use your syntax, I get a message saying the "Opendll.dll" does not exist?
>I used : newobject("Opendbf","Opendbf","Opendll.dll")
>If I try : ? file("Opendll.dll"), VFP returns true ???
>
>Any idea?
