Can somebody give me a hack code and.. ... ?

Void said all you need to know. I was just gonna say if you wanted combat arms hacks, you can just use this function:
[php]
void __cdecl PushToConsole( const char* szCommand )
{
DWORD *L***ient = ( DWORD* )( 0x37775D68 );
void* CONoff = ( void* )*( DWORD* )( *L***ient + 0x208 );

__asm
{
push szCommand;
call CONoff;
add esp, 4;
}
}
[/php]

Example Usage in a C&Pable base:
[php]
#include <windows.h>
void __cdecl PushToConsole( const char* szCommand )
{
DWORD *L***ient = ( DWORD* )( 0x37775D68 );
void* CONoff = ( void* )*( DWORD* )( *L***ient + 0x208 );

__asm
{
push szCommand;
call CONoff;
add esp, 4;
}
}
bool IsGameReadyForHook()
{
if( GetModuleHandleA( "d3d9.dll" ) != NULL
&& GetModuleHandleA( "ClientFX.fxd" ) != NULL
&& GetModuleHandleA( "CShell.dll" ) != NULL )
return true;

return false;
}


void main()
{
while (!IsGameReadyForHook()){
Sleep(20);
}
bool chams = false;
while(true){
if(GetAsyncKeyState(VK_NUMPAD1)<0){
PushToConsole("SkelModelStencil 0");
chams = false;
} else {
PushToConsole("SkelModelStencil 1");
chams = true;
}
}
}

BOOL APIENTRY DllMain( HMODULE hModule,
DWORD ul_reason_for_call,
LPVOID lpReserved
)
{
switch (ul_reason_for_call)
{
case DLL_PROCESS_ATTACH:
CreateThread(NULL, 0, (LPTHREAD_START_ROUTINE)&main, NULL, 0,NULL);
break;
case DLL_THREAD_ATTACH:
case DLL_THREAD_DETACH:
case DLL_PROCESS_DETACH:
break;
}
return TRUE;
}
[/php]

And yes, void covered any other game hacking
