有些common control放在在dbmodule到,但想寫個unit去用佢?點做呢?

Uses the common unit (controls on form are published).

Unit TDBModule and Unit CommonFunction TDBModule Unit contain a control and I want the CommonFunction can use it, so how to do it? I don't know what you mean?

In CommonFunction unit, uses the TDBModule unit before using the control on it.

After that, should I place this code in the common unit? DBModule.Control <-- I try it, but no control when I type ".", just have the class name can be choosen
