I done it!!!! I did so: 1) OnCreate i put this as you told me:
CMFCToolBar::AddToolBarForImageCollection(IDR_MAINFRAME_256);
in Contextmenu i add these lines:
CMFCPopupMenu* PopupMenuFolders = new CMFCPopupMenu();
//Mi serve controllare prima che esce il menu per eventualmente eliminare voci del menu non permesse.
CheckWhatCanIDo(ExtractFullTreePath(htSelectedTreeItem),MainComputerinfo.szSid,m_bUserAuthorizations);
PopupMenuFolders->InsertItem(CMFCToolBarMenuButton(ID_POPUP_FOLDERS_TREE_1, NULL, 0, _T("Item 1")));
PopupMenuFolders->InsertItem(CMFCToolBarMenuButton(ID_POPUP_FOLDERS_TREE_2, NULL, 1, _T("Item 2")));
PopupMenuFolders->InsertItem(CMFCToolBarMenuButton(ID_POPUP_FOLDERS_TREE_3, NULL, 2, _T("Item 3")));
PopupMenuFolders->Create(this, point.x, point.y, NULL);
So you use directly the Toolbar Images. Thanks all ;) Giovanni
