Send packet ,No response to the game

DWORD g_55F8A6 = 0x55F8A6;
void __declspec (naked) Old55F8A0(char *arg)
{
__asm
{
push ebp;
mov ebp,esp;
push esi;
mov esi,ecx;
jmp g_55F8A6;
}
}
void sendpkt()
{
//build packet

PARAM Param = BuildParam((DWORD)&myPacket);

DWORD dwClassPt = GetClassPointer();

__asm
{
mov ecx,dwClassPt;
lea eax,Param;
push eax;
call Old55F8A0;
}



}
No response to the game,why?
how to fix it.

You seems to not be using the right function and you aren't even encrypting your packet before sending it.

What the hell? You're calling the wrong function.

void SendPacket( CDataStore* pDataStore )
{
    __asm
    {
        MOV EDX, pDataStore
        PUSH EDX

        MOV EAX, CurrentConnection__GetConnection
        CALL EAX
        MOV ECX, EAX

        MOV EAX, CurrentConnection__SendPacket
        CALL EAX
    }
}

#define CurrentConnection__SendPacket        0x0055F8A0
#define CurrentConnection__ReceivePacket    0x0055F440
#define CurrentConnection__GetConnection    0x005B3B80

void SendPacket( CDataStore* pDataStore )

i use this code
also Send packet ,No response to the game

Then you're sending the wrong packet. What are you trying to send exactly?
