Ok, im making a program that will inject a DLL into another program, by making a remote thread, and attaching the function from the DLL to the thread. But, when i inject, the program im trying it on (mIRC), crashes. My guesses are: 1) Im loading the library (DLL) in my memory space, and referencing to my memory space, which would crash it, but, i thought DLL where all in shared memory space. 2) mIRC counts it own thread numbers for injection, and crashes itself (very unlikely) Here is my source for injection, i already have a valid handle to the program:
			 // Validate we have the Handle.
				 MessageBox::Show("For some reason the hook was lost, please re-attach.","Error!", MessageBoxButtons::OK, MessageBoxIcon::Exclamation);

			 // Load the DLL into memory space
			 HMODULE DLL = LoadLibrary("../EnableConsole/EnableConsole.dll");
				 MessageBox::Show("Failed to load DLL! Please check that it exists.", "Error!", MessageBoxButtons::OK, MessageBoxIcon::Exclamation);

			 void* DLLFunctionAddress = GetProcAddress(DLL, "InjectionThread");
			 CreateRemoteThread(SWGHandle, NULL, NULL, (LPTHREAD_START_ROUTINE)DLLFunctionAddress, NULL, NULL, NULL); 

and here is my very simple DLL:
#include <windows.h>

extern "C" __declspec(dllexport) void InjectionThread()
