import a matlab com

[nishna]

hi to all.
i have a matlab project which i have to import to vb.net.
im using a comtool to create a dll to reference the project.

the code is as follows:

Imports MWComUtil
Imports try1

Public Class Form1
    Dim test As try1.try1class = New try1.try1class
    Dim mw As MWComUtil.MWUtil


    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        test.frmwel()
    End Sub
End Class

However i get errors like :

Error	1	Argument not specified for parameter 'nargout' of 'Public Sub frmwel(nargout As Integer, ByRef varargout As Object, varargin As Object)'.	C:\Documents and Settings\nishna\My Documents\Visual Studio 2005\Projects\try\comtry\comtry\Form1.vb

any idea how to correctly call the dll(project works fine in matlab).

thnks
regards, nishna
