+/*
+ *@@ dlghFormatDlg:
+ *      similar to dlghCreateDlg in that this can
+ *      dynamically format dialog items.
+ *
+ *      The differences however are the following:
+ *
+ *      --  This assumes that hwndDlg already points
+ *          to a valid dialog frame and that this
+ *          dialog should be modified according to
+ *          flFlags.
+ *
+ *      flFlags can be any combination of the following:
+ *
+ *      --  DFFL_CREATECONTROLS: paDlgItems points to
+ *          an array of cDlgItems DLGHITEM structures
+ *          (see dlghCreateDlg) which is used for creating
+ *          subwindows in hwndDlg. By using this flag, the
+ *          function will essentially work like dlghCreateDlg,
+ *          except that the frame is already created.
+ *
+ *      --  DFFL_RESIZEFRAME: hwndDlg should be resized so
+ *          that it will properly surround the controls.
+ *
+ *          This can only be used in conjunction with
+ *          DFFL_RESIZEFRAME.
+ *
+ *@@added V0.9.16 (2001-09-29) [umoeller]
