Window without client area in WinAPI

Question

On these screenshots we can see unordinary window frame in different applications:

QIP logo on its login window frame (not client area) - http://postimage.org/image/2fdjg0h44/
Buttons (back/next) and address field on the Windows 7 explorer window frame - http://postimage.org/image/2fdrpp7l0/
In Google Chrome tabs take place on the window frame

In all these windows client area is resized or/and replaced. Of course, it works with Windows Aero theme only.

I want to resize and replace client area of my window or hide it at all if it is possible. (C/C++ and Win API). How can I do it?

Pretty tricky to get this right. Start here: http://delphihaven.wordpress.com/2010/04/19/setting-up-a-custom-titlebar/ — David Heffernan, Oct 12 '11 at 22:17

That effect is accomplished using the DwmExtendFrameIntoClientArea function.

You are looking to resize the nonclient area of the form: Controls and the Desktop Window Manager
