Lua ToString And Getlocalized text

[haku43]

Hi, i need some help with returning values from DoString, which works fine.

 public void DoString(string lua)
            {
                Synchronize();
                uint codeCave = _magic.AllocateMemory(0x2048);

               _magic.WriteBytes(codeCave + 0x1024, Encoding.UTF8  .GetBytes(lua));
                // _magic.WriteASCIIString(codeCave + 0x1024, lua);

                _magic.Asm.Clear();
                AsmUpdateCurrentManager();

                //_magic.Asm.AddLine("push {0}", State);
                _magic.Asm.AddLine("push {0}", 0);
                _magic.Asm.AddLine("mov eax, {0}", codeCave + 0x1024);
                _magic.Asm.AddLine("push eax");
                _magic.Asm.AddLine("push eax");
                _magic.Asm.AddLine("call {0}", (uint)Offsets.Lua.Lua_DoString);
                _magic.Asm.AddLine("add esp, 0xC");
                _magic.Asm.AddLine("retn");

                _magic.Asm.InjectAndExecute(codeCave);
                _magic.FreeMemory(codeCave);
                ResumeMainThread();
            }

This doesn't return anything, but doesn't crash.

Lua.DoString("result1251 = " & cmdstr)
result = Lua.GetLocalizedText("result1251")

public byte [] GetLocalizedText(string lua)
            {
                Synchronize();
                uint codeCave = _magic.AllocateMemory(0x256 );

               // _magic.WriteBytes(codeCave + 0x256, Encoding.UTF8.GetBytes(lua));

                _magic.Asm.Clear();
                 AsmUpdateCurrentManager();

                _magic.Asm.AddLine("mov ecx, {0}", BlackRain.Common.Objects.ObjectManager.Me.BaseAddress);// BlackRain.Common.Objects.ObjectManager.Me.BaseAddress);
                _magic.Asm.AddLine("push {0}", -1);
                _magic.Asm.AddLine("push {0}", codeCave + 0x128);
                _magic.Asm.AddLine("call {0}", (uint)Offsets.Lua.Lua_GetLocalizedText);
                _magic.Asm.AddLine("retn");



                     uint result = _magic.Asm.InjectAndExecute(codeCave);

                byte[] sResult = new byte [128]; 
                if (result != 0)
                {
                    sResult = _magic.ReadBytes(result, 128);
                }

                ResumeMainThread();
                return sResult;

            }

This one crashes.

 public string ToString(int argument, int length)
            {
             
                uint codeCave = _magic.AllocateMemory(0x1024);
                AsmUpdateCurrentManager();
                _magic.Asm.Clear();
                _magic.Asm.AddLine("push {0}",0);
                _magic.Asm.AddLine("push {0}", argument);
                _magic.Asm.AddLine("push {0}", State );
                _magic.Asm.AddLine("call {0}", (uint)Offsets.Lua .LuaToString);
                _magic.Asm.AddLine("add esp, 0xC");
                _magic.Asm.AddLine("retn");

                uint result = _magic.Asm.InjectAndExecute(codeCave);
                System.Console.WriteLine("ToString: {0:X}", result);

                _magic.FreeMemory(codeCave);
             
                try
                {
                    return _magic.ReadASCIIString(result, length);
                }
                catch (Exception e)
                {
                    return "";
                }
            }

           public override string ToString()
            {
                return ToString(GetArgument(), 100);
            }

  private int GetArgument()
            {
                if (LastArg < GetTop())
                {
                    LastArg++;
                }
                return LastArg;
            }



 public int GetTop()
            {
                uint codeCave = _magic.AllocateMemory(0x1048);
                _magic.Asm.Clear();
                _magic.Asm.AddLine("push {0}", State);
                _magic.Asm.AddLine("call {0}", (uint)Offsets.Lua.LuaGetTop);
                _magic.Asm.AddLine("add esp, 0x4");
                _magic.Asm.AddLine("retn");

                uint result = _magic.Asm.InjectAndExecute(codeCave);
                _magic.FreeMemory(codeCave);
                return (int)result;
            }

     public uint GetState()
            {
                uint codeCave = _magic.AllocateMemory(0x1048);

                _magic.Asm.Clear();
                _magic.Asm.AddLine("call {0}", (uint)Offsets.Lua.LuaGetState);
                _magic.Asm.AddLine("retn");

                uint result = _magic.Asm.InjectAndExecute(codeCave);
                _magic.FreeMemory(codeCave);
                return result;
            }
           private void ResumeMainThread()
            {

                SThread.ResumeThread(MainThread);
          
            }

            private void Synchronize()
            {
                SThread.SuspendThread(MainThread);             
            }

I want to write a simple bot, which will iteract with world using WoW API.
Is it rationally to use this aproach without callbacks to get the return values?

I dont think you will get a reply, this is a repost. A lot of people ask this question and it has been answered. Most likely and infraction will be the result of this.

Well i am actualy not asking "How to",there is something wrong with the code, i need help to make it work.

Look at GetLocalizedText in IDA. You'll see your mistake. One of them at least.
