Me.Controls can get all the controls on the form, but i want to get all the
controls include non-from controls, for example ToolTip, ContextMenuStrip...
Thank you

I think because they don't inherit Control class, as a result they're
not identified as controls.
See which classes/interfaces they implement. For example ToolTip class
inherits Component class, not control:
http://msdn.microsoft.com/en-us/library/system.windows.forms.tooltip.aspx

So, you can loop Components to get them as follows:

For Each comp As System.ComponentModel.Component _
In Me.components.Components
' Tooltip and ContextMenuStrip will be found here
Next

Hope this helps,

Because the 'components' field in a form is Private, therefore it is
visible only from within the form.
 
You are a expert, thank you, but if this code is in moulde sub, for example:

Public sub AAA(Byval FormName as Form)
    For Each comp As System.ComponentModel.Component In
FormName.components.Components
        ' Tooltip and ContextMenuStrip will be found here
   Next
End Sub

The code above will not work if replace "Me" with "FormName", why?
Thank you

Thanks for the feedback,

For the problem, as Jack said, "components" variable supplied with
Private access modifier within that form. To call through other form,
you need to call the loop from other form using "Me".
