Child windows

Hi,

I'm a bit confuse on what child windows are.

I'm trying to find a sample code that can show me the basis of it, but I can find any.

Can some one provide me a simple example?

basically any windows application has to have a primary window ( even if tis now visible) in order to recieve and process windows messages. This is the Parent window. A child window is an additional window(s) that you create whose lifetime is dependant upon the parent window. This is of particular importance when making a multi-document interface style program, (MDI) where the child windows are bound within the parent window. This was more of an issue in 16 bit windows. In 32 and 64 bit windows programs are no longer created as child windows of some other window unless explicitly forced to do so.

thanks for the explanation
