Switching between different ribbons in an MDI application

I'd like to switch between different ribbons for different MDI child frames in my application. I know it's possible with the old style menus, but I can't get it working with the feature pack ribbons.

The code used when it's old style menus:

pDocTemplate = new CMultiDocTemplate(
    IDR_MAINFRAME,//Menu to load
    RUNTIME_CLASS(CModDoc),
    RUNTIME_CLASS(CModFrame), // custom MDI child frame
    RUNTIME_CLASS(CdotView));
if (!pDocTemplate)
    return FALSE;
AddDocTemplate(pDocTemplate);

pDocTemplate = new CMultiDocTemplate(
    IDR_RES_RNGACTIV,//Menu to load
    RUNTIME_CLASS(CModRangeDoc),
    RUNTIME_CLASS(CModRangeFrame), //custom MDI child frame
    RUNTIME_CLASS(CBlankView));
if (!pDocTemplate)
    return FALSE;
AddDocTemplate(pDocTemplate);

Another approach I'm thinking of is to unload the current Ribbon and load a new Ribbon from resources?

//Unload ribbon code?
m_wndRibbonBar.LoadFromResource(IDR_RIBBON);

Solution

there is no need to have multiple CMFCRibbonBar objects if you don't need to, you can just use the CMFCRibbonBar::LoadFromResource and then you will have to use the CMFCRibbonBar::RecalcLayout method to apply the changes to the User Interface. Remember to check the return value of CMFCRibbonBar::LoadFromResource to be sure that the load was successful, and it is really important that you call the CMFCRibbonBar::RecalcLayout otherwise you will not see the new ribbon.
