You really need to take more time to formulate your questions. Once I even thought overnight before posting, because I couldn't figure out a decent title.

So before you post any more of this, think about these, for example..

1. What are you doing now?
2. What do you want to do?
3. If you have code, post it.
4. If it's a design matter, try to be as specific as possible while explaining it.

People understand English is not everyone's first language, but if you can't figure out the answers to these questions in your own language, then you probably need to think a bit more about your problem.

With the time already wasted figuring out what you want, you would've probably written at least a half-decent start for a thread.
