ReadProcessMemory

Hi,

When using read process memory, here is an example:

dim lngBaseAdd as long
dim lngResult as long
dim lngReadBytes as long

lngBaseAdd = &HF0129F 'or some arbitrary base address

When using the read process memory API you must pass the lngBaseAdd by value, why?

ReadProcessMemory hProcess, lngBaseAdd, lngResult, 4, lngReadBytes '<--- FAILS
ReadProcessMemory hProcess, byVal lngBaseAdd, lngResult, 4, lngReadBytes '<--- WORKS

I dont get why you must pass it by value.



Thanks.
Brian
