Thanks very much for ur reading.
OK, let me give out more description, the situation is:
there are some buttons in the MainForm, and the numbers of these buttons will be changed if needed.
While the numbers of buttons change, there will leave a blank area in the button place which should be hided according to my demand(the blank problem appears just a flash then the backgroud return to normal).

if u have any doubt about my explanation pls tell me, thanks a lot in advance for ur answer and suggestion

It's still not clear what's the problem and what do you want. Help us to help you. Could you show us screenshots or something? Maybe you want something like this: [wiki]Expanding dialog[/wiki]?
