I included a exe file as a resource in my c++ application and i need to run it, but i need to restrict it’s access alot so the user can’t copy it.
I need to keep it’s handle opened so external programs can’t access it, and because i used FILE_FLAG_DELETE_ON_CLOSE as a flag, so it will delete if my application gets killed.

But because of that i can’t run it with CreateProcess() or WinExec().
I know it sounds weird, but i have a good reason.I need those to protect the executable of a game from a dll-injection cheat, and i don’t have the code of that exe.

    Since you can’t lock the entire file, lock a very small part with LockFile. You’ll need to find a byte range that Windows doesn’t use. You might achieve this by adding a dummy resource to the EXE. (This does not require source code).
