thanks, that makes it much clearer. I added the following lines right before
calling GetCommandString():

hMenu = CreatePopupMenu();
Win32Check(hMenu != NULL);

OleCheck(menu->QueryContextMenu(hMenu, 0, 0, 2, CMF_NORMAL));


however, now the call to GetCommandString() throws 'Not implemented'.

What could be wrong? Also QueryContextMenu() requires parameters
for first and last command. What should I specify when I don't know the
number of available commands ahead?

thanks for your help!
