How to make Flowstone send PC keyboard key-press commands?

Postby keyjslider1 » Thu Apr 05, 2018 5:25 pm

Dear Sirs,

by default the Flowstone reacts to PC keybord key-press messages by means of standard prim "Is Key Pressed".
Is there the way to perform the opposite operation (like with MIDI Message prim) - to send (emulate) specific key-pressed messages out of Flowstone, in my case, to the DAW host?
My need is to emulate "Home" key pressure command to send out of Flowstone to activate/reset FL Studio mixer channel position.
I guess there might be neccessary to address to external API32 application?

Would very much appreciate someone to share ideas and possibly, the code examples.... Thanks in advance.

This belongs to "General", as it is not at all about DSP ;)

I never used it myself, so I don't have Ruby code for you, but what you need is from the Windows API

SendMessage (with the WM_KEYUP or WM_KEYDOWN message)
Windows Dev Center link

However, the function expects a handle to the window that will receive the message, which will require you to find out that handle. I'm a little lost on that topic, maybe somebody else can help with that?

Tulamide thank you, SendKey and SenMessage do not work out of Flowstone as a FLStudio plugin, but Postmessage works fine. For my purpose I used keybd_event command, I didn't need finding out the window handle because the target window was always on top when the desired code had to be applied. I used the following code to send "Home" key in order to reset the FL's mixer position^
require "Win32API"
g=Win32API.new("user32","keybd_event", ['i','i','p','i'])
g.call(36,0,0,0)
g.call(36,0,'KEYEVENTF_KEYUP',0)
