If I load a menu to CExtButton mButton:
    CMenu _menu;
    _menu.LoadMenu(menuID)
... do something to modify/add menu items
    mButton->m_menu.Attach(_menu.Detach());

The menu works fine except the ownerdraw code doesn’t draw the menu check marks. is there a way to make the menu checks visible?

What the ownerdrawn code you mean? The CPagePopupMenus::OnDrawPopupMenuItem() method of the ProfUIS_Controls sample handles the CExtPopupMenuWnd::g_nMsgPopupDrawItem registered windows message and repaints the command item identified with ID_OWNERDRAW_ITEM in the context menu on the "Popup Menus" dialog. If this is not what you mean please, please clarify the issue.

I mean that if I create a menu resource with checked items and then load it to CExtButton m_menu member the ProfUUIS ownerdraw code doesnot draw the checkmarks! I need to be able to draw check marks at run-time and as far as I can see from you samples there is no code for this.

Each menu/toolbar item controls its status (enabled/disabled, checked/unchecked) via MFC command updating mechanism. So, you can make a menu item checked by providing an update handler for the command ID (simply add the ON_UPDATE_COMMAND_UI handler for this command):

afx_msg void OnUpdateYourCommand(CCmdUI* pCmdUI);

...
 
ON_UPDATE_COMMAND_UI(ID_YOUR_COMMAND, OnUpdateYourCommand)
 
...
 
void CMainFrame::OnUpdateYourCommand( CCmdUI * pCmdUI ) 
{
 pCmdUI->SetCheck( m_bChecked ? 1 : 0 );
}
