Premetto che sono un principiante .
Vorrei usare delle funzioni all'interno di una DLL di Matlab.
Ho una DLL Libeng.dll la quale contiene i seguenti files.
engClose
engEvalString
engGetArray
ecc.
In un modulo .bas inserisco:
Private Declare Function Eval Lib "Libeng.dll" Alias "engEvalstring" (ByVal
x As String) As String
Quindi :
Private Sub Command1_Click()
Dim y As String

y = Eval(Text1.Text)
MsgBox y
End Sub

Ho il messaggio :' impossibile trovare il punto di ingresso della DLL
evalstring in libeng.'

Come posso risolvere il problema?
Tante grazie per l'aiuto.
