Private Sub CommandButton1_Click()
        Dim test As BIOVALIDATEUSER_INFOA
        Dim lResult As Long
        lResult = BioInit(0)
 
        test.lpstrUsername = "opleynet"
        test.lpstrDomain = "domaine"
        test.dwAuthProvider = 1
        test.dwStructSize = Len(test)
        'Call BioValidateUser Function
        '
        lResult = BioValidateUser(test)
End Sub
 
et mon.bas
