    Moved.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    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.

    I have a list box as my main window, with also a File, Tools etc menu on it. I just open up a dialog as the main 'window' without all that extra window crap, then used Visual Studio to make a List Box... Easy enough?
