I am writing a C# program which captures signals from a external device, and sends keystrokes to another application. I am using SendKeys and it works fine.

SendKeys does ‘press’ a key by holding and releasing it immediately. I would like to make it push key and release it at will.

My question is : ‘is there a way to send a ‘push’ signal to a key, then a ‘release’ signal after a certain amount of time ?’

I am not sure SendKeys is able to do this. Any clue ?

  1. I don’t think it’s possible from .NET directly You could try using keybd_event native call by p/invoking the function as described here: http://pinvoke.net/default.aspx/user32.keybd_event

    The MSDN for keybd_event is here: http://msdn.microsoft.com/en-us/library/ms646304(VS.85).aspx

    Hope that helps!
