MenuRef GetControl32BitValue always return 0

Answer 1

You probably want to handle kEventClassCommand/kEventProcessCommand, and use the command id from the menu item.

HICommand           command;

GetEventParameter( inEvent, kEventParamDirectObject, typeHICommand, NULL,
            sizeof( HICommand ), NULL, &command );

switch (command.commandID) {
    case 1:
      ... etc ...

Note that the commandID is one of the parameters to AppendMenuItemTextWithCFString; that's how you can give each item a unique commandID as you generate the menu. commandID's are conventionally 4-char codes (like 'open' or 'save'), but there's no reason you couldn't use simple ints for your dynamically-generated commands.
