C# Simulate Key Press

I was looking for a way to simulate pressing the right Ctrl key in C#, it must be the right one. I know this can be done for the left one but I couldn't find anything on the right one. It is so I can simulate the key press for the manually triggered bsod.

Thanks

Solution

  • You can use keybd_event event to simulate right Ctrl key press. 

    [DllImport("user32.dll", SetLastError = true)]
static extern void keybd_event(byte bVk, byte bScan, int dwFlags, int dwExtraInfo); 

public const int KEYEVENTF_EXTENDEDKEY = 0x0001; //Key down flag
public const int KEYEVENTF_KEYUP = 0x0002; //Key up flag
public const int VK_RCONTROL = 0xA3; //Right Control key code

    Usage:

    keybd_event(VK_RCONTROL, 0, KEYEVENTF_EXTENDEDKEY, 0);
keybd_event(VK_RCONTROL, 0, KEYEVENTF_KEYUP, 0);
