Update:Data and Code in stack

I was testing how to implement code execution or storing data in stack I found that using forward pointer from esp e.g.: add esp,4 will not help for large size codes/data cause it result in Access violation ,so instead using a backward pointer from esp e.g sub esp,100h is better and I think it is more reliable .
Another thing regarding code execution in stack ,I heard vista will not let that happen ,as a protective way against shellcodes in exploits usage ,correct me if I am wrong .
