◆ MSG_COMMAND

#define MSG_COMMAND 0x0120

The command message, indicates a notification message from child window, or the user has selected a menu item.

This message sent to the window when the user has selected a menu item, or a child window has sent a notification message to the parent.

MSG_COMMAND
int id = LOWORD(wParam);
int code = HIWORD(wParam);
HWND hwnd = (HWND)lParam;

Parameters

id	The identifier of the menu item or the child window.
code	The notification code.
hwnd	The handle to the control.

Note: If you use MSG_COMMAND message to handle the notification sent from other windows, you should make sure the identifier value and the notification code do not exceed half of the maximal value of a DWORD (32-bit on 64-bit platform, and 16-bit on 32-bit platform). If you use a pointer as the identifier, the code above will not work.

Instead, we recommend strongly that you use a NOTIFYPOROC callback to handle the notification generated by a window.
