silly memory question ...

hi all,

i'm looking to do something stupid. can anyone tell me why it won't work? (is there some kind of special protection on EXE memory pages?)

i have an application, App1, that has a 64KB function (64KB of NOP) "void funcX(void)". App1 opens a socket to another application, App2, which is going to feed code to App1 to stick in funcX.

that is, i've got some other set of functions i plan on feeding to App1 and they're all going to look like "funcX" to App1. those functions are coming from App2, which is chewing on a bunch of var-things to spit out just the right code for App1.

now, when i try to do this, i get Random Stuff. sometimes, i just get a segfault. sometimes, it seems to work, but the memory at funcX is hosed if i do a hex-dump compared to what i received from App2. either way, it isn't doing what i want...

is there some trick here to make this work? or am i SOL?

[is there a better place to ask this question?]

thanks,

josh
