To simulate the click of a menu you do not send any message to the menu itself, you just send the same message that the menu does when clicked. That is, send WM_COMMAND to the owner window of the menu, with old good SendMessage.

When choosing an option from a menu, the parameters are:

  • wParam: the identifier (16 lower bits) of the command to be sent.
  • lParam: 0.

If you don't know the value of the identifier, you can use a monitor program such as Spy++ (included with most VS versions) to list the messages sent/received by your program.
