[Help] As an end hook is created?

I need to learn to create and update private hooks, as public hooks are detected faster. I do not intend to ever leave atualizandos hooks, leave it to learn more forward. but the least we need is to learn how to create, how it is made, of which extract data. I do not understand much when I see those parts of hooks DIP, as they are created. for example:

Code:
__declspec(naked) DWORD __stdcall pDrawIndexedPrimitive(LPDIRECT3DDEVICE9 pDevice, D3DPRIMITIVETYPE Type, INT BaseVertexIndex, UINT MinIndex,UINT NumVertices, UINT StartIndex, UINT PrimitiveCount)
{
__asm
{
MOV EDI,EDI
PUSH EBP
MOV EBP,ESP
jmp jump_DrawIndexedPrimitive
}
}

HRESULT _stdcall my_DrawIndexedPrimitive(LPDIRECT3DDEVICE9 pDevice, D3DPRIMITIVETYPE Type, INT BaseVertexIndex, UINT MinIndex,UINT NumVertices, UINT StartIndex, UINT PrimitiveCount)
{

return pDrawIndexedPrimitive(pDevice, Type, BaseVertexIndex, MinIndex, NumVertices, StartIndex, PrimitiveCount);
font of the code: playerup.com/forum/showthread.php?t=1175113


how this can be undetectable, where retreat this information? It seems to be extracted by OllyDbg, but how it's done. I could just buy a ready hook, but really want to learn to create from scratch. I try to learn how to create the months, and did not think anything about it. I doubt the type: one hook end is for any form of menu (tab or select)? I did not want to ask for something for free, but do not know what to do to learn, no one teaches only say it is difficult, but if others can do I can also create. please, help-me.

sorry for my bad english =[
