The information in this article applies to:

- Microsoft Visual Basic Professional Edition for Windows, version 6.0 
- Microsoft Terminal Services Advanced Client, version 1.0 
-------------------------------------------------------------------------------

SUMMARY
=======

The Terminal Services ActiveX client control does not expose the
ImsTscNonScriptable interface. However, this interface can be used to configure
automatic log on for a Terminal Services Session programmatically, which enables
the programmer to log a user on to a Terminal Services Session without receiving
the Windows Logon prompt. This is demonstrated in the sample in the "More
Information" section.

MORE INFORMATION
================

To run this program, configure your Terminal Server computer as follows:

1. Log on to the Terminal Server locally as an administrator.

2. On the Start button, click Programs, click Administrative Tools, and then
  click Terminal Services Configuration.

3. Click on Connections.

4. In the right pane, right-click RDP-Tcp, and then choose Properties.

5. Click on the Logon Settings tab.

6. Deselect Always prompt for password, and then click OK.

NOTE: For security reasons, Microsoft recommends that you do not implement this
scenario without extreme care and a clear understanding of Microsoft Windows
security.

Sample Code
-----------

1. Start a new Standard EXE project. Form1 is created by default.

2. On the Project menu, click to select Components, select Microsoft Terminal
  Services Control(redist), and then click OK. If this control is not
  available, see the "References" section of this article for information on
  how to download and install it.

3. Add one Terminal Services Control to Form1, making sure it is big enough to
  handle the display of the session.

4. Add three Label controls, three TextBox controls, and one CommandButton
  control to Form1. Make sure that Lable1 and Text1 are on the same line, and
  that Label2, Text2, Label3, and Text3 are on the same line.

5. Paste the following code into the General Declarations of Form1:

  ' This code only works when you set the configuration on the Server-side.
  ' Log on to the Terminal Server as an administrator
  ' Start\Programs\Administrative Tools\Terminal Services Configuration
  ' Click on Connections
  ' On the Right Pane, right-click on RDP-Tcp and choose Properties
  ' Click on the "Logon Settings" Tab
  ' Uncheck "Always prompt for password" and click OK

  Option Explicit

  Private Obj As IMsTscNonScriptable

  Private Sub Form_Load()
    Text1.Text = ""
    Text2.Text = ""
    Text3.Text = ""
    Label1.Caption = "Server"
    Label2.Caption = "UserName"
    Label3.Caption = "Password"
    Command1.Caption = "Connect"
    Text3.PasswordChar = "*"
  End Sub

  Private Sub Command1_Click()
    Set Obj = MsTscAx1.Object
    MsTscAx1.Server = Text1.Text
    MsTscAx1.UserName = Text2.Text
    Obj.ClearTextPassword = Text3.Text
    MsTscAx1.Connect
  End Sub

6. Save the project, press the F5 key to run it, and note that after you supply
  your username, password, and server name, you are not prompted for a logon
  screen at the server. Microsoft recommends that you enlarge the Terminal
  Server .ocx file so that you are able to manipulate the Shut Down dialog box.
