>any idea how i can obfusicate my VFP code ?

No, it is useless. Any crypting of vfp can be hacked and anything can be re"compiled". So even the use of lala and IaIa (I hope you see the diff) is not of much help.

For fools there are some ways like the obvious play with l and I; O and 0 using of macro substitution, redefine commands via #DEFINE etc, but this is kids play.

OTOH the simple use of BINDEVENT() instead of coding inside an event, RAISEEVENT(oObject,cEventVar) etc makes a lot of fun for code analyzing. I have good results with a table based classfactory and instantiating objects on the fly. Adding CONTROLSOURCES on the fly.
IOW the place where something happens is not visible from the form, since the business object (DATAENVIRONMENT) and the CURSORADAPTERS are not declared in the form.

But again, this is all traceable. The idiots I deal with are simple to numb to understand the use of debugger and the properties of an object. :)
