use the

WS_CHILD style

in the

CreateWindowEx()

cast the

HMENU

param to an int ID number

(HMENU)IDC_MYCHILDCTRL,

I like to define them

#define IDC_MYCHILDCTRL 40001

the

hWndParent

defines the callback (wndproc) to which the controls messages will be sent.

Remember to

InitCommonControlsEx()

if using the more complex controls

You will have to code for different window sizes / resizes ect
