EZTW32.DLL scanner TWAIN with vb.net

I have found an example of code for VB5 using tawin.

I have try to translate it in vb.net but some object changed.

Does anyone has an idea about the correct code ?

Thanks :p

VB Code:

Option Strict Off
Option Explicit On
Module Module1
    ' 32-bit EZTWAIN functions for Visual Basic 5.0
    Declare Function TWAIN_AcquireToClipboard Lib "EZTW32.DLL" (ByVal hwndApp As Integer, ByVal wPixTypes As Integer) As Integer
    Declare Function TWAIN_SelectImageSource Lib "EZTW32.DLL" (ByVal hwndApp As Integer) As Integer
End Module
 
 
 
 
    Private Sub Command1_Click(ByVal eventSender As System.Object, ByVal eventArgs As System.EventArgs) Handles Command1.Click
        Dim r As Object
 
        r = TWAIN_SelectImageSource(Me.Handle.ToInt32)
    End Sub
    
    Private Sub Command2_Click(ByVal eventSender As System.Object, ByVal eventArgs As System.EventArgs) Handles Command2.Click
        Dim r As Object
        Dim t As Short
 
        r = TWAIN_AcquireToClipboard(Me.Handle.ToInt32, t)
 
        Dim iData As IDataObject = Clipboard.GetDataObject
        Picture1.Image = iData.GetData
        
    End Sub
