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 ?
