Newbie, having a problem upgrading from VB6 to dotNet.
I am trying to call some subs from a NIST dll and I don't know how to
call them in Net.
I have used the Upgrade VB6 wizzard on my old source and got a Modual
and a form.
Module NIST_Module
Public Declare Sub SETUPdll Lib "Refprop" (ByRef i As Integer,
ByVal hfld As String, ByVal hfmix As String, ByVal hrf As String, ByRef
ierr As Integer, ByVal herr As String, ByRef ln1 As Integer, ByRef ln2
As Integer, ByRef ln3 As Integer, ByRef ln4 As Integer)
Public Const MaxComps As Integer = 20
Public herr, hfmix, htyp As String
Public hrf As String
Public htype, hmix, hcomp As String
Public hfld As String, nc As Long
Public ierr As Long
"more stuff"
End Module
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles Button1.Click
nc = 1
hfld = "C:\NIST\fluids\nitrogen.fld"
hfmix = "C:\NIST\fluids\hmx.bnc"
hrf = "DEF"
'setup for Nitrogen
Call SETUPdll(nc, hfld, hfmix, hrf, ierr, herr, 10000&, 255&,
3&, 255&)
Unable to load DLL 'Refprop': The specified module could not be found.
(Exception from HRESULT: 0x8007007E)
'Get molecular weight:
Call WMOLdll(x(1), wm)
End Sub
End Class
What else do I need or what order do I need to do it in?
