// Input: nSwapOutID - The command ID of the menu item, defined in the menu resource,

// that should be replaced.

// nCommandID - The command ID to add to the menu.

// szName - The menu string to add.

// Summary: Call this method to set one or more swapout IDs, in the case where

// there is a dynamic menu item. An example of where this can be used is

// the MRU in a standard doc/view application. Add a single command

// to the menu resource that can be swapped out with the commands you

// set here. Call this method once for each command you want to replace.

// For example, if you had a command ID called IDC_MRUPLACEHOLDER, and

// you wanted to add four new items in place of this which are IDC_MRUFILE1,

// IDC_MRUFILE2, IDC_MRUFILE3, IDC_MRUFILE4 you should do the following: -

    //          <pre>

// kbsm.AddSwapoutCommand(IDC_MRUPLACEHOLDER, IDC_MRUFILE1, "File 1");

    //          kbsm.AddSwapoutCommand(IDC_MRUPLACEHOLDER, IDC_MRUFILE2, "File 2");

    //          kbsm.AddSwapoutCommand(IDC_MRUPLACEHOLDER, IDC_MRUFILE3, "File 3");

    //          kbsm.AddSwapoutCommand(IDC_MRUPLACEHOLDER, IDC_MRUFILE4, "File 4");</pre>

void AddSwapoutCommand(UINT nSwapOutID, UINT nCommandID, LPCTSTR szName);

I read the above but cannot see how to use it.
