    There is no pre-defined Logon Control for NCo, but it's terribly simple to create one on your own: If you only need some parameters, create a form, drop a Destination or SAPLogonDestination and some TextBoxes and databind the needed properties of the destination with the TextBoxes.

    If you need a full-featured Logon Control, you best use a CombinedDestination and a DataGrid control. This is what we use internally to add a new SAP server to Server Explorer.

    • Here is the sample Logon Control in VB (you could of cause have the same in C# as well):

      Public Class SAPLogonForm

      Inherits System.Windows.Forms.Form

      #Region " Windows Form Designer generated code "

      Public Sub New()

      MyBase.New()

      'This call is required by the Windows Form Designer.

      InitializeComponent()

      'Add any initialization after the InitializeComponent() call

      End Sub

      'Form overrides dispose to clean up the component list.

      Protected Overloads Overrides Sub Dispose(ByVal disposing As Boolean)

      If disposing Then

      If Not (components Is Nothing) Then

      components.Dispose()

      End If

      End If

      MyBase.Dispose(disposing)

      End Sub

      'Required by the Windows Form Designer

      Private components As System.ComponentModel.IContainer

      'NOTE: The following procedure is required by the Windows Form Designer

      'It can be modified using the Windows Form Designer.

      'Do not modify it using the code editor.
