Hi all:

I want to read memory from a process...the code is as below:

   BYTE buf[4];
   DWORD addr;
   STARTUPINFO si;
   PROCESS_INFORMATION pi;

   ZeroMemory(&si, sizeof(STARTUPINFO));
   si.cb=sizeof(STARTUPINFO);
   if(!CreateProcess("c:\\winnt\\notepad.exe", 0, 0, 0, 0,
CREATE_NEW_CONSOLE, 0, 0, &si, &pi))
   {
      ShowMessage("could not create process - "+IntToStr(GetLastError()));
   }
   WaitForInputIdle(pi.hProcess, INFINITE);
   addr=0;
   DWORD dummy;

   if(!ReadProcessMemory(pi.hProcess, 0, buf, 4, &dummy))
   {
      ShowMessage("could not read process memory -
"+IntToStr(GetLastError()));
      ShowMessage("dummy = "+IntToStr(dummy));
   }
   CloseHandle(pi.hProcess);
   CloseHandle(pi.hThread);

But, this line "ReadProcessMemory" occurs error at runtime.
And the error code is 299 (Only part of a ReadProcessMemory or
WriteProcessMemory request was completed. ).
Is there something wrong what I do? I have no idea...Please help me.

Thanks.
RaynorPao.

According to the documentation:

    "The entire area to be read must be accessible, or the operation fails."

What exactly are you trying to accomplish?

Hi Remy:

Thanks for your reply.
I just want to read memory block from the process which I created.
Is there something wrong what I do? Please help me.

Thanks.

But, what KIND of memory block exactly?  You didn't answer my question
fully - what EXACTLY are you trying to accomplish with this?
