How to delete Server Objects saved in the QVW.shared File

[#1]

Hello everybody,

i create buttons as a server object with the following code:
set button = ActiveDocument.Sheets("Start").CreateButton

When i look at the server after creating this button, i see a server object called BU01.
So far so good.

If i want to delete this created button, i use the following code:
objs=s.GetButtons
for b=lbound(objs) to ubound(objs)
objs(b).Close
next

When i have a look at the server now, i see the server object BU01 is still existing there.
My question: How to remove a created Button from the server?

Thanks for your help!

I found another thread handling the same problem:
http://community.qlik.com/forums/t/39478.aspx

The solution there was, to use the drop-down icon on the IE Plugin toolbar --> Server Objects --> Remove. This way works, but there must exist a possibility, to remove these server objects with a macro, too!

Any suggestions?
