Hi,
been working all night on this without getting it to work. Need some help if anyone knows what might be wrong.

It's quite big main source so I dont want to paste it all right now.
After use OpenProcess(...)
i do ReadProcessMemory(hProcess, &baseaddr, buffer, PAGESIZE, 0)..

i try this on a simple notepad.exe process. what i want to do is to read the bytes (or text if you prefer) from that process.

PID: 3104, Handle: 0000000000000040
i know pid's and handles change each time one runs or restarts computer or applications in background. i try the correct pid in my example, but i get error message each time. LastError shows this:

Error: Only part of a ReadProcessMemory or WriteProcessMemory request was completed.
I tried to change the UAC to HighestPossible in the Visual C++ Express properties for the Linker->Manifest properties.

The compiler and linker is set to 64-bit. And notepad runs in 64-bit after looking it in the Task Manager.

Also i want to know where in memory to search for the program's virtual address space.

Code:
HANDLE hProcess = OpenProcess(PROCESS_VM_READ, FALSE, entry.th32ProcessID);
i've tried PROCESS_ALL_ACCESS too, even though i dont think its necessary. it gives the same error anyway.

the process is open while doing this:

Code:
                    if (ReadProcessMemory(hProcess, &baseaddr, buffer, PAGESIZE, 0) != 0)
                    {
                        //success!
                    }
                    else
                    {
                        //fails
                        //here i do LastError routine..
                    }
what might be causing this?
Error: Only part of a ReadProcessMemory or WriteProcessMemory request was completed.
what else should I do?
anyone have any suggestions?
