Send keys is broken in vbs/w10 and documented to be so when doing a google...so Im guessing that may be why input_event is broken ie api changes.
I have tried autoit and its send still works if I run it from the editor...however using pd 'system' to run the script or exe doesnt seem to work...so def stuck...and for anyone trying to send an undo to Live for looping...it really does present a shop stopper...
Any ideas?

Sendkeys seems to work in Microsoft Visual Studio Express 2015.
If that helps
I just did this to test it
However I found I needed to send System.Windows.Forms.SendKeys.Send("%+(E)+({ENTER})") to create an undo in Ableton Live Lite 8 which is equivalent to Alt+E+enter because "^(Z)" doesn't seem to work but "^(T)" works to insert a MIDI track but should insert an audio track.
System.Windows.Forms.SendKeys.Send("%(C)({DOWN}{DOWN}{ENTER})") equivalent to Alt+C+down+down+enter does insert an audio track

Hmm. Just read that it's been removed. Weird. Anyway...input_event def seems dead...anyone out who can fix the dll? Or at least confirm the problem?

@image_engine In case it helps.....
The download is still "out there"...... http://s184785159.onlinehome.fr/drupal/?q=node/171
and contains the .c file for the object [input_event]
David.

Cool...I'm not a c guy though...anyone else on the forum do a compile check? Does anyone have a w10 machine to confirm...maybe it's me???

Hi,
you can send a '/live/undo' to live via OSC using the liveOSC midi remote script.

Thanks @bang; that sounds like a great solution. I have taken the plunge and bought max 4 live as it removes a whole bunch of issues and makes the simpler extremely simple. Now Im just hoping everything that was programmed works in M4L without too much trouble :-\

@image_engine Good news that you are getting somewhere with resolving your problems. There is more and more discussion on the web currently, of the problems with SendKeys...... not removed from Widows10, but purposefully broken.
I repeat strongly that you must image your machine when you have everything working.
An OS that "evolves" on a daily basis is absolutely not useful to anybody using it in a critical situation (or anybody else ).
I rather like this........

hehe...too true. Windows 10 is hideous for updates...metered connection seems to be the only saviour.

Max for Live seems to be ok...most of the PD stuff can be copied verbatim...mostly.

Understanding the Object Model is a little tough but just bought a book on it...dont have the time to fumble so its worth it.

Your help has been amazing David!

I didnt realise you could make a vst out of pd...that would have probably stopped me going further ie Live max.

Cheers
Mark
