I am trying to make a macro engine for a personal project, and it would work fine, except that the form won't show when I debug it. Take it for granted that I am using the LuaInterface DLL please.

using System.Collections.Generic;

using System.Text;
using System.Windows.Forms;
using LuaInterface;
using System.Runtime.InteropServices;

namespace Lua_Macroez
    public partial class Form1 : Form
        public Form1()

            lua.RegisterFunction("MoveMouse", formStuff, formStuff.GetType().
                GetMethod("MoveMouse")); //Registers the mouse moving event
            lua.RegisterFunction("LeftCLick", formStuff, formStuff.GetType().

        [DllImport("User32.dll", SetLastError = true)]
        public static extern int SendInput(int nInputs, ref INPUT pInputs,
                                           int cbSize);

        //mouse event constants
        const int MOUSEEVENTF_LEFTDOWN = 2;
        const int MOUSEEVENTF_LEFTUP = 4;
        //input type constant
        const int INPUT_MOUSE = 0;

        Lua lua = new Lua(); //creates a new lua interpereter
        Form1 formStuff = new Form1(); 

        //This makes the functions that the lua executes later
        public void MoveMouse(int xval, int yval)
            Cursor.Position = new Point(xval, yval);

        public void LeftClick()
            //set up the INPUT struct and fill it for the mouse down
            INPUT i = new INPUT();
            i.type = INPUT_MOUSE;
            i.mi.dx = 0;
            i.mi.dy = 0;
            i.mi.dwFlags = MOUSEEVENTF_LEFTDOWN;
            i.mi.dwExtraInfo = IntPtr.Zero;
            i.mi.mouseData = 0;
            i.mi.time = 0;
            //send the input 
            SendInput(1, ref i, Marshal.SizeOf(i));
            //set the INPUT for mouse up and send it
            i.mi.dwFlags = MOUSEEVENTF_LEFTUP;
            SendInput(1, ref i, Marshal.SizeOf(i));

        //Function creation ends
        //struct that contains data for stuff
        public struct MOUSEINPUT
            public int dx;
            public int dy;
            public int mouseData;
            public int dwFlags;
            public int time;
            public IntPtr dwExtraInfo;

        public struct INPUT
            public uint type;
            public MOUSEINPUT mi;

        //structs end

        private void buttonExecute_Click(object sender, EventArgs e)

        private void Form1_Load(object sender, EventArgs e)



Edited 6 Years Ago by LuaMan: bad title

You do realize that formStuff is not the currently active form and is never shown in this code and it is the form you tie lua to?

Sheeeeit I figured out the problem.

lua.RegisterFunction("MoveMouse", this, this.GetType(). //<-- problem fixed
                GetMethod("MoveMouse")); //Registers the mouse moving event
            lua.RegisterFunction("LeftCLick", this, this.GetType().
