Making the hack

So , few days ago i was learning how to make some simple hacks [a hotkey] and like i use microsoft visual studio 2010 after i create the hack put the code in , i find no dll , only a c++ file and im wondering which one is the hack to put into the injector ?

ugh ur name looks good but it should say leeching4life147. just saying... if you can code im pretty sure you will be able to find the .dll file.
on topic the .dll file is in Documents\Visual Studio 2010\Projects\ur project name\Release if you just learned a few days ago you will prob crash just sayin
