Call Lua callback in DLL cause some Error

[rafaelcn]

I try to run BabBot ,but the code in this function cause some error like this:
System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.

the trouble line is
int n = Lua_GetTop(Lua_GetState());

public static int InputHandler(uint luaState)
        {
            lock (dataLock)
            {
                try
                {
                    Log("InputHandler() - Calling ...");

                    Values.Clear();

                    int n = Lua_GetTop(Lua_GetState());
                    Log("InputHandler() - Lua_GetTop(Lua_GetState() Done!");

                    Log(string.Format("InputHandler() - Passed LUA_State (ignored): {0:X}", luaState));
                    Log(string.Format("InputHandler() - Our own LUA_State: {0:X}", Lua_GetState()));
                    Log("InputHandler() - Vars num: " + n);

                    for (int i = 1; i <= n; i++)
                    {
                        string res = Lua_ToString(Lua_GetState(), i, 0);
                        Log(string.Format(
                                                "InputHandler() - Var[{0}] = {1}", i, res));
                        Values.Add(res);
                    }

                    Log("InputHandler() - Done");
                }
                catch (Exception e)
                {
                    Log("InputHandler() exception: " + e.ToString());                
                }

                ValueReceived = true;
            }
            return 0;
        }

Anyone have some idea for this ?

Are you starting Visual Studio as admin?
Are you using the correct offsets?

[rafaelcn]

the offset should be right, I found them in ollydbg by myself. but thx a lot. I'll try to use these offset to a console project to check them .

[rafaelcn]

Viano is right, my offsets have some problem. It work fine for me when I fixed these offsets.
