How to simulate keypress

Question

I know how to use SendKeys() but how do i go about it if i would like to simulate holding ESCAPE key for like 5 seconds?

Answer 1

You can PInvoke keybd_event and hold down Escape key for 5 seconds and then release it:

[DllImport("user32.dll")]
static extern void keybd_event(byte bVk, byte bScan, uint dwFlags, UIntPtr dwExtraInfo);


keybd_event(VK_ESCAPE, 0, 0, 0) // KEY_DOWN

System.Threading.Thread.Sleep(5000);

keybd_event(VK_ESCAPE, 0, KEYEVENTF_KEYUP, 0) // KEY_UP
