Alright, so what we are going to cover are some basic things,

Creating Threads,
WriteProcessMemory,
GetAsyncKeyState.

Alright lets get started,
go create an empty project in VC++ 2008.

Add a new file to the source folder called
Code:

Main.cpp


Now, Lets Get on to the real coding, Don't forget to include your header.

First we are going to get the
Code:
UL_Reason_for_call
.

The one we are going to use, is
Code:
DLL_PROCESS_ATTACH
,

That means, when the DLL is injected to the process.

So lets start. Include your header
Code:
#include <windows.h>


Now, lets get the simple API ENTRY Code,
Code:
BOOL APIENTRY DllMain( HMODULE hModule,DWORD  ul_reason_for_call,LPVOID lpReserved)
{


}


Now lets add our CALL reason.

Code:
if(ul_reason_for_call == DLL_PROCESS_ATTACH)
{

}


So it would look something like this.

Code:
BOOL APIENTRY DllMain( HMODULE hModule,DWORD  ul_reason_for_call,LPVOID lpReserved)
{
if(ul_reason_for_call == DLL_PROCESS_ATTACH)
{

}



}


Now lets create a simple Thread, Called Halo.

Code:

CreateThread(NULL, 0, (LPTHREAD_START_ROUTINE)&Halo, 0, 0, NULL);


So now it should look like this :
Code:
BOOL APIENTRY DllMain( HMODULE hModule,DWORD  ul_reason_for_call,LPVOID lpReserved)
{
if(ul_reason_for_call == DLL_PROCESS_ATTACH)
{
CreateThread(NULL, 0, (LPTHREAD_START_ROUTINE)&Halo, 0, 0, NULL);
}
}


Lets continue, lets add the code at the top..

Note the : &Halo, thats the name of our thread.
But Erase the & so it's : Halo

Let's continue on.

Add this above your code,
Code:

bool Halo(void)
{



}

Now here you can use a simple MessageBox, using the
Code:
MessageBoxA
Command.

But we're going to skip that.. Lets continue,

Lets add a loop for the hotkeys.
Code:

for(;;(Sleep(250)))
{

}


for(;Wink is our loop, but i added a Sleep to it,because it can be very laggy.

Now it should look somthing like :

Code:

bool halo(void)
{
for(;;(Sleep(250)));
{


}

}


Now, lets get this tutorial done, Lets use the
Code:
GetAsyncKeyState
Now.

add this inbetween the 2 brackets of the loop.
Code:

if(GetAsyncKeyState(VK_F1))
{

}


That means, if you press F1 then..etc

Now heres a simple hack for Halo CE Trial,

Code:


************************
* HUD *
************************
* Address = 0x4BAD03BC *
* On = 0x01 *
* Off = 0x00 *
************************

(Credits to HaloTrialHacking.com)

To toggle the HUD off,


So add this inbetween the two brackets of the GetAsyncKeyState

Code:

   BYTE One9[0xC] = {0x01};
   WriteProcessMemory(((HANDLE)-1), (void*)0x4BAD03BC, &One9,1, 0);


And inject it! that should be all

Final code :
Code:

#include <windows.h>




bool Halo(void)
{

for(;;(Sleep(250)))
{

if(GetAsyncKeyState(VK_F1))
{
      BYTE One9[0xC] = {0x01};
      WriteProcessMemory(((HANDLE)-1), (void*)0x4BAD03BC, &One9,1, 0);
}





}
return 0;
}





BOOL APIENTRY DllMain( HMODULE hModule,DWORD  ul_reason_for_call,LPVOID lpReserved)
{
if(ul_reason_for_call == DLL_PROCESS_ATTACH)
{
CreateThread(NULL, 0, (LPTHREAD_START_ROUTINE)&Halo, 0, 0, NULL);
}
}

Me : For tutorial.


EDIT : If i'm wrong can someone please correct me?

Your formatting is fucked.

WriteProcessMemory is pointless in a DLL, you already have direct access to the memory if you're injected.

that's what you should use. Something like this is imo the easiest way.

Code:
DWORD* blah = (DWORD*)0x00123456;
*blah = 0x01;


or you could just do this, which is probably what it'd compile into anyway.

Code:
mov dword ptr ds:[0x00123456], 0x01
