[Help] Program freeze on injection

[=manzarek=]

Hi,
I use ihook for my injections, but it freeze when executing:

bool ManagedFasm::Inject(DWORD dwAddress)
{
return this->Inject(m_hProcess, dwAddress);
}

From fasmdll_managed

My Code:

 string command = "DoEmote(\"Dance\")";
            uint Frame_Execute_Offset = (uint)Offsets.EndScene.FrameScript_ExecuteBuffer + (uint)wowBase; // Lua_DoString
            Memory.OpenProcess(MyPid);
            //uint ret = Memory.VirtualAllocEx(Memory.ProcessHandle, 0, 1024, Memory.MemoryAllocType.MEM_COMMIT | Memory.MemoryAllocType.MEM_RESERVE, Memory.MemoryProtectType.PAGE_EXECUTE_READWRITE);
            uint ret = Memory.AllocateMemory(Encoding.UTF8.GetBytes(command).Length + 1);
            Memory.WriteBytes(ret, Encoding.UTF8.GetBytes(command));
            String[] asm = new String[] 
            {
                "mov eax, " + ret,
                "push 0",
                "push eax",
                "push eax",
                "mov eax, " + Frame_Execute_Offset,
                "call eax",
                "add esp, 0xC",
                "retn",    
            };
            Hook.InjectAndExecute(asm);
            Hook.Restore();

Local variables on BP:

Before calling InjectAndExecute:


VS i running with administrator right fasm is compiled with .net 4.0.

What did i make wrong?

+Bonus noob question: is IHook detected by Warden.

Thank you

Use the internal Lua library functions rather than these FrameScript functions. Being completely documented, they're much easier to understand how you should call them.

Use these functions instead:
luaL_loadbuffer: Lua: Functions and Types: luaL_loadbuffer - 0x0011EBA0 in 5.0.5 (rebased).
lua_pcall: Lua: Functions and Types: lua_pcall - 0x0011DF50 in 5.0.5 (rebased).

Thank you for the advise i'll take a look.
I should not ask question after midnight when i'am tired,

This is working:

string command = "DoEmote(\"Dance\")";
uint Frame_Execute_Offset = (uint)Offsets.EndScene.FrameScript_ExecuteBuffer + (uint)wowBase; // Lua_DoString
Memory.OpenProcess(MyPid);
//uint ret = Memory.VirtualAllocEx(Memory.ProcessHandle, 0, 1024, Memory.MemoryAllocType.MEM_COMMIT | Memory.MemoryAllocType.MEM_RESERVE, Memory.MemoryProtectType.PAGE_EXECUTE_READWRITE);
uint ret = Memory.AllocateMemory(Encoding.UTF8.GetBytes(command).Length + 1);
Memory.WriteBytes(ret, Encoding.UTF8.GetBytes(command));
String[] asm = new String[]
{
"mov eax, " + ret,
"push 0",
"push eax",
"push eax",
"mov eax, " + Frame_Execute_Offset,
"call eax",
"add esp, 0xC",
"retn",
};
uint D3D9_Device;
D3D9_Device = Memory.Read<uint>((uint)Memory.BaseAddress + (uint)Offsets.EndScene.Direct3D9__Device);
D3D9_Device = Memory.Read<uint>(D3D9_Device + (uint)Offsets.EndScene.Direct3D9__Device__OffsetA);
D3D9_Device = Memory.Read<uint>(D3D9_Device);
D3D9_Device = Memory.Read<uint>(D3D9_Device + (uint)Offsets.EndScene.Direct3D9__Device__OffsetB);
Hook.Apply(D3D9_Device, (uint)Offsets.EndScene.ClntObjMgrGetActivePlayerObj, (uint)Offsets.EndScene.FrameScript_ExecuteBuffer, (uint)Offsets.EndScene.FrameScript__GetLocalizedText);
Hook.InjectAndExecute(asm);
Hook.Restore();

I forgot to initialize Hook, i go kill myself now.

Thank you anyway Jadd
