Moved.

making the list box a child window

This is the preferred approach. Create the main, parent window in your WinMain function and create the child listbox control in its WM_CREATE handler.

i want it to resize to the parent window`s size always

Handle the parent's WM_SIZE message and use MoveWindow with the listbox control's handle - there's a description of a similar issue in this recent thread which should be of some help in this regard.
