How to lock file in Windows so that this file can be opened/read/wrote only by one process?

I found out that file can be locked with CreateFile by giving 0 to dwShareMode flag. It works but only the returned handle can be used to work with file. But I want to be able to lock the file to other processes and at the same time to create multiple handles in my process.

Please help me to solve this issue or give some tips...
