I am trying to build a clickbot in C#, but i have some problems.

The click works, but it keeps clicking at the location where the cursor currently is located and not at the x and y position.

I used the following code and inserted the x and y positions.

        mouseDownInput.mkhi.mi.dx = 1809;
        mouseDownInput.mkhi.mi.dy = 93;

I also tried adding 

            mouseDownInput.mkhi.mi.dwFlags = MouseEventFlags.MOUSEEVENTF_LEFTDOWN | MouseEventFlags.MOUSEEVENTF_ABSOLUTE;

How to programmatically mouse move,click,right click and keypress, etc. in winform and wpf?

public class MouseSimulator
{
    [DllImport("user32.dll", SetLastError = true)]
    static extern uint SendInput(uint nInputs, ref INPUT pInputs, int cbSize);

    [StructLayout(LayoutKind.Sequential)]
    struct INPUT
    {
        public SendInputEventType type;
        public MouseKeybdhardwareInputUnion mkhi;
    }
    [StructLayout(LayoutKind.Explicit)]
    struct MouseKeybdhardwareInputUnion
    {
        [FieldOffset(0)]
        public MouseInputData mi;

        [FieldOffset(0)]
        public KEYBDINPUT ki;

        [FieldOffset(0)]
        public HARDWAREINPUT hi;
    }
    [StructLayout(LayoutKind.Sequential)]
    struct KEYBDINPUT
    {
        public ushort wVk;

    }
    enum SendInputEventType : int
    {

    }

    public static void ClickLeftMouseButton()
    {
        INPUT mouseDownInput = new INPUT();
        mouseDownInput.type = SendInputEventType.InputMouse;
        mouseDownInput.mkhi.mi.dx = 1809;
        mouseDownInput.mkhi.mi.dy = 93;
        mouseDownInput.mkhi.mi.dwFlags = MouseEventFlags.MOUSEEVENTF_LEFTDOWN;
        SendInput(1, ref mouseDownInput, Marshal.SizeOf(new INPUT()));

        INPUT mouseUpInput = new INPUT();
        mouseUpInput.type = SendInputEventType.InputMouse;
        mouseUpInput.mkhi.mi.dx = 1809;
        mouseUpInput.mkhi.mi.dy = 93;
        mouseUpInput.mkhi.mi.dwFlags = MouseEventFlags.MOUSEEVENTF_LEFTUP;
        SendInput(1, ref mouseUpInput, Marshal.SizeOf(new INPUT()));
    }
    public static void ClickRightMouseButton()
    {

        mouseDownInput.type = SendInputEventType.InputMouse;

    It won't work as you think it would - meaning, you can't have 2 cursors - where you have one moving freely and another one clicking where you please. You can ofcourse send click event with a pos to a window, but not in desktop in general. – JTinkers Mar 01 '19 at 08:27
  • How can i send a click at a specific position or a button input to a program? Do you have a keyword which i can use for further research? – fipps omat Mar 01 '19 at 08:41
  • Yes, search for `C++ window send mouse event` You can also just check here: https://stackoverflow.com/questions/25245607/windows-send-mouse-keyboard-event-to-background-window – JTinkers Mar 01 '19 at 15:02
  • Go to codeproject.com and search for global mouse keyboard library. – Chris Dunaway Mar 01 '19 at 16:45
