The api call looks like this Declare Function ReadProcessMemory Lib "kernel32" (ByVal hProcess As Long, lpBaseAddress As Any, lpBuffer As Any, ByVal nSize As Long, lpNumberOfBytesWritten As Long) As Long My code looks like this dim str as string ReadProcessMemory pHandle, BaseAddress,str, 1, 0& Text1.text = str It is supposed to simply read the address of what is written in a notepad file, all of the declrations are correct to get the handle and the base address, I know this becuase I wrote a similar chunk of code using writememoryprocess and it WORKED. I think the problem exists somewhere in the lbuffer part of the call.

================================================================== The way you have it, it is declared as a statement rather than an assignment/function. Try it this way: ReadProcessMemory(pHandle, BaseAddress,str, 1, 0 & Text1.text)=str Also, pHandle is being passed to a variable reference byRef rather than byVal...you may want to check the rest of these and look for similar trouble. borelli35
