Question

My app will need to simulate a key being held down during some time. I don't know how many time. Can I use the sendinput API for this?

Was it helpful?

Solution

SendInput can trigger events with INPUT structures including KEYBDINPUT. A KEYBDINPUT can specify key up and key down events using virtual keys or scan codes. So you want to use SendInput twice: send a key down event at the beginning, and a key up event at the end.
