WinAPI: No WM_COMMAND Message?

[aldente]

Hello!

I'm trying to remote control an application using SendMessage. When you send ALT+P to that application, it does what it should do, but I want to control it directly by sending a message. So I do NOT want to send KEYDOWN and KEYUP messages, but the message that invokes the proper function (normally WM_COMMAND). Instead, there are hundreds of strange other messages within less than one second.

The problem with this app is: There are no WM_COMMAND messages, like in 'normal' applications, so I'm a bit confused Maybe some API-expert can help me?

This is what happens after lifting the last key (press ALT, press P, lift P, lift ALT):
