Is there some way that I can send multimedia control commands like next song, pause, play, vol up, etc. to the operating system?
Commands that are sent when pressing Fn + some mapped ..key.
I am making a remote control for PC and sending those commands is essential.
你可以使用keybd_event来模拟按键，你必须模拟按键按下然后按键按下才能正确识别
[DllImport("user32.dll", SetLastError = true)]
public static extern void keybd_event(byte virtualKey, byte scanCode, uint flags, IntPtr extraInfo);
public const int VK_MEDIA_NEXT_TRACK = 0xB0;
public const int VK_MEDIA_PLAY_PAUSE = 0xB3;
public const int VK_MEDIA_PREV_TRACK = 0xB1;
public const int KEYEVENTF_EXTENDEDKEY = 0x0001; //Key down flag
public const int KEYEVENTF_KEYUP = 0x0002; //Key up flag
private void ButtonClick(object sender, EventArgs e)
keybd_event(VK_MEDIA_PREV_TRACK, 0, KEYEVENTF_EXTENDEDKEY, IntPtr.Zero);
keybd_event(VK_MEDIA_PREV_TRACK, 0, KEYEVENTF_KEYUP, IntPtr.Zero);
}`
