DM_RESETSCROLL

  • Article

The DM_RESETSCROLL message is sent by a dialog box to reset scroll information when the dialog box redoes the re-layout of child controls after the Windows CE WM_INITDIALOG message is sent. A dialog box does not need to send this message if it does all layout of child controls at or before the WM_INITDIALOG message is sent.

The DM_RESETSCROLL message is supported only if the dialog box has the WS_VSCROLL style.
