Edit Control Questions

I have two questions. The first is how would I make a set of Edit Controls with Scrollbars scroll simultaneously? I'd like to even have a scrollbar on each one and hve them scroll at the same time no matter which one I use. What message would I use?

Oh, and is it possible to create an edit box that is editable only by the program or should I just use a Listbox?

MSDN WM_VSCROLL .

Just intercept this message through your windowproc, use GetScrollPos to get where one control is at and use SetScrollPos to set the second scrollbar.

Code:

---

case WM_VSCROLL: {
    int nScrlPos;
    /*
          Get Scroll Bar Position
          lParam is the Handle of the control sending the position
    */
    nScrlPos = GetScrollPos(lParam, SB_VERT);

    /*
          Set the sister control scroll bar to the same position
          Remember, the positions are relative, the heights are
          not the same, the scroll bars will not look as if they are
          scrolling in sync
          g_hEditCtrl2 is the handle of the second edit control
    */
    SetScrollPos(g_hEditCtrl2, SB_VERT, nScrlPos, TRUE);

    /*
          The link above links to the GetScrollPos and SetScrollPos
          so you can get more in depth info
    */

    break;
}

Hope that helps...
