Hello,

I have problem with define external function with dll written in Visual Basic.

Declaration of function is

Declare Function Tsat_p Lib "c:\Xsteam_V2.6b.dll" Alias "Tsat_p@8" (ByVal p As Double) As Double


Well I tried these, but there is an error.

restart;
f:=define_external( 
     'Tsat_p', 
     LIB="d:/kohoutek/Xsteam_V2.6b.dll",
     'p'::float[8],
RETURN::float[8]):
Error, external lookup of Tsat_p: Uvedená procedura nebyla nalezena.
 

Could you help me please?

Thanks a lot.
