Oh, I know this all.

I said you can't call this function directly as showed at the following code:

to build DLL from VFP and then:

********* at the VFP *************************************
declare dummer in "LibraryName" STRING

or
'********* at the VB (VBA) *************************************
declare sub dummer lib "LibraryName" (msg as String)

and call this function (without getting the error message)

dummer( "Hello from dummer!!!")

**********************************************

Alex.
