The TBSTATE_WRAP flag is not supported by MMC. The MMCBUTTON structure should not have its fsType member set to include the TBSTATE_WRAP flag. The IToolbar::AddButtons, IToolbar::InsertButton, and IToolbar::SetButtonState methods use the caller's fsType value when managing a toolbar button. In MMC 2.0, setting the TBSTATE_WRAP flag is ignored; in earlier versions of MMC, setting the TBSTATE_WRAP flag for a button causes the next toolbar button to appear in the next line.
