When using HTML Help Workshop, only Toolbar is executed, there is no Menu (MSDN has Menu), after I have a painstaking work, I finally discovered the method:
Use the user-defined window to edit the HHP files as follows: [Windows] wzht = "Learn Notes", "Notes. HHC", "Notes. HHK", "Home.htm", "Home.htm" ,,,,, 0x31520,, 0x70307E, [60, 73, 556, 376], 0x1000000, 0x0,, 0,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, 1, 3, 5, 7, 9, b, d, f (odd) can guarantee the menu.
