Set a form global variable in the form's declaration section (above the load
event):

Public closetest As Boolean = True

If you have a close button that you want to allow you to get out of the
form, change the status of closetest to false.  Then, in the closing event
of the form:

If closetest = True Then

e.Cancel = True

End If

HTH,

Bernie Yaeger

add this to the form:

Protected Overrides ReadOnly Property CreateParams() _
           As System.Windows.Forms.CreateParams
   Get
       Const CS_NOCLOSE As Integer = &H200
       Dim Params As CreateParams = MyBase.CreateParams
       Params.ClassStyle = Params.ClassStyle Or CS_NOCLOSE
       Return Params
   End Get
End Property

CAUTION: You wont be able to close the form from anywhere except the task
manager (or if you are in debug mode, using the stop button in the IDE).

hope that helps..
Imran.

Add this to your form:

\\\
Protected Overrides ReadOnly Property CreateParams() As CreateParams
   Get
       Dim cp As CreateParams = MyBase.CreateParams
       Const CS_DBLCLKS As Int32 = &H8
       Const CS_NOCLOSE As Int32 = &H200
       cp.ClassStyle = CS_DBLCLKS Or CS_NOCLOSE
       Return cp
   End Get
End Property
///

Alternatively you can remove the according menu items from the system
menu using p/invoke.
