Hello Pedro,

I have used netcdf with VB and got the same error message ("Bad
> DLL Calling Convention"). You can suppress this message with "On error
resume next". The netcdf functions then work fine for me.

In your call to the netcdf function nc_create you should however send string
variables ByVal and not ByRef!

Hope, this will help you

Best regards
H.J. Rieger
