/*
 *  BUTTON LISTBOX CONTROL
 *
 *  The Button Listbox control creates an array of buttons that behaves
 *  similar to both a button and a listbox: the array may be scrollable
 *  like a listbox and each listbox item is behaves like a pushbutton
 *  control
 *
 *
 *  SPECIFYING A BUTTONLISTBOX IN THE DIALOG TEMPLATE
 *
 *  The CONTROL statement in the dialog template specifies the
 *  dimensions of each individual button in the x, y, width and height
 *  parameters. The low order byte in the style field specifies the
 *  number of buttons that will be displayed; the actual size of the
 *  displayed control is determined by the number of buttons specified.
 *
 *  For a standard control--no other style bits set--the width of the
 *  control in dialog base units will be
 *      CX = cx * (n + 2/3) + 2
 *  where cx is the width of the button and n is number of buttons
 *  specified. (The 2/3 is for displaying partially visible buttons for
 *  scrolling plus 2 for the control borders.) The control will also be
 *  augmented in the cy direction by the height of the horizontal scroll
 *  bar.
 *
 *  If the BLS_NOSCROLL style is set, no scroll bar will appear and the
 *  button listbox will be limited to displaying the number of buttons
 *  specified and no more. In this case, the width of the control will
 *  be
 *      CX = cx * n + 2
 *
 *  If the BLS_VERTICAL style is set, the entire control goes vertical
 *  and cy should be substituted in the above calculations to determine
 *  CY, the actual height of the displayed control.
 *
 *  The statement
 *
 *  CONTROL  "", IDD_BUTTONLIST, "buttonlistbox", 0x0005 | WS_TABSTOP,
 *           4, 128, 34, 24
 *
 *  creates a scrollable horizontal list of 5 buttons at the position
 *  (4,128) with each button having dimensions (34,24). The entire control
 *  has the tabstop style.
 *
 *
 *  ADDING BUTTONS TO A BUTTONLISTBOX CONTROL
 *
 *  Buttons are added to the listbox in the same manner that items are
 *  added to a standard listbox; however, the messages BL_ADDBUTTON and
 *  BL_INSERTBUTTON must be passed a pointer to a CREATELISTBUTTON
 *  structure in the lParam.
 *
 *  Example:
 *
 *  {
 *      CREATELISTBUTTON clb;
 *      const int numColors = 1;
 *      COLORMAP colorMap;
 *
 *      colorMap.from = BUTTON_MAP_COLOR;   // your background color
 *      colorMap.to   = GetSysColor(COLOR_BTNFACE);
 *
 *      clb.cbSize = sizeof(clb);
 *      clb.dwItemData = BUTTON_1;
 *      clb.hBitmap = CreateMappedBitmap(hInst,BMP_BUTTON,FALSE,
 *                      &colorMap,numColors);
 *      clb.lpszText = "Button 1";
 *      SendMessage(GetDlgItem(hDlg,IDD_BUTTONLIST),
 *                  BL_ADDBUTTON, 0,
 *                  (LPARAM)(CREATELISTBUTTON FAR*)&clb);
 *      DeleteObject(clb.hBitmap);
 *  }
 *
 *  Note that the caller must delete any memory for objects passed in
 *  the CREATELISTBUTTON structure. Also, the CreateMappedBitmap API is
 *  useful for mapping the background color of the button bitmap to the
 *  system color COLOR_BTNFACE for a cleaner visual appearance.
 *
 *  The BL_ADDBUTTON message causes the listbox to be sorted by the
 *  button text whereas the BL_INSERTBUTTON does not cause the list to
 *  be sorted.
 *
 *  The button listbox sends a WM_DELETEITEM message to the control parent
 *  when a button is deleted so that any item data can be cleaned up.

/*
// OVERVIEW:
//
// The UpDown control is a simple pair of buttons which increment or
// decrement an integer value.  The operation is similar to a vertical
// scrollbar; except that the control only has line-up and line-down
// functionality, and changes the current position automatically.
//
// The control also can be linked with a companion control, usually an
// "edit" control, to simplify dialog-box management.  This companion is
// termed a "buddy" in this documentation.  Any sibling HWND may be
// assigned as the control's buddy, or the control may be allowed to
// choose one automatically.  Once chosen, the UpDown can size itself to
// match the buddy's right or left border, and/or automatically set the
// text of the buddy control to make the current position visible.
//
// ADDITIONAL NOTES:
//
// The "upper" and "lower" limits must not cover a range larger than 32,767
// positions.  It is acceptable to have the range inverted, i.e., to have
// (lower > upper).  The upper button always moves the current position
// towards the "upper" number, and the lower button always moves towards the
// "lower" number.  If the range is zero (lower == upper), or the control
// is disabled (EnableWindow(hCtrl, FALSE)), the control draws grayed
// arrows in both buttons.  The UDS_WRAP style makes the range cyclic; that
// is, the numbers will wrap once one end of the range is reached.
//
// The buddy window must have the same parent as the UpDown control.
//
// If the buddy window resizes, and the UDS_ALIGN* styles are used, it
// is necessary to send the UDM_SETBUDDY message to re-anchor the UpDown
// control on the appropriate border of the buddy window.
//
// The UDS_AUTOBUDDY style uses GetWindow(hCtrl, GW_HWNDPREV) to pick
// the best buddy window.  In the case of a DIALOG resource, this will
// choose the previous control listed in the resource script.  If the
// windows will change in Z-order, sending UDM_SETBUDDY with a NULL handle
// will pick a new buddy; otherwise the original auto-buddy choice is
// maintained.
//
// The UDS_SETBUDDYINT style uses its own SetDlgItemInt-style
// functionality to set the caption text of the buddy.  All WIN.INI [Intl]
// values are honored by this routine.
//
// The UDS_ARROWKEYS style will subclass the buddy window, in order to steal
// the VK_UP and VK_DOWN arrow key messages.
