>1) I was wondering how secure are executables built by VFP. Can people get to my code inside the executable.

Yup. Hackers can. Check out refox .

>2) The size of my executable is growing by leaps and bounds as continue developing. I am half way through the project but the executable is already 5 MB. Is this normal and are there any disadvantages to the executable being so big (load time is a concern). Are there any remedies for this.

Mine is 3.7 meg. It still sounds reasonable.
