Simulating keyboard input

[jen2276]

Hi! I'm trying to write a background app that receives input from an external
device (through the comm port) and then sends that data to the active
foreground window that has focus. So far I have gotten this working using
the "keybd_event" function to send the data to the foreground window, but it
works for local apps only. When I RDP out to another machine and set focus
on a notepad session or command prompt window on the remote machine, the data
never makes it over. Any ideas?

You may want to take a look at SendInput().

Frankly, I have no idea if it works in the remote case but I think that it
exists to work around some of the limitations of keybd_event().

Thanks! SendInput combined with MapVirtualKey did the trick.
