Re: [Tutor] using while loop for read process memory

Sorry Alan, Steve, everyone Can you take a look of this please? Here is my question about the memory: So I have a base address of a chunk of memory from it's size, from VirtualQueryEx (if you dont use windows, it's ok, it's not about how u get these values, because I think the base concept is

Re: [Tutor] using while loop for read process memory

in fact, when I am using this: end = start + mbi.RegionSize I was getting error from the ReadProcessMemory function, and I couldn't figure it out why. Until I did this: end = current_address + mbi.RegionSize - 7 then it doesn't complain anymore. I think it's because I ran this

Re: [Tutor] using while loop for read process memory

I have no idea about ctypes or Windows, but it seems to me that you are creating a rod for your own back by using a while loop here. Why use a primitive, low-level looping construct when Python gives you much better tools? My *guess* is that somewhere you are miscalcuating when to stop, and

This is the red part index = current_address end = current_address + mbi.RegionSize while index < end: if ReadProcessMemory(Process, index, ctypes.byref(buffer), \ ctypes.sizeof(buffer), ctypes.byref(nread)): ## value

[Tutor] using while loop for read process memory

Hi all: I have the following code, and somehow I must have fed the read process Memory incorrectly. what the code does is to check a region of memory to see whether or not it can be scanned. mbi.Protect == PAGE_READWRITE and mbi.State == MEM_COMMIT If this is true,then it proceeds to scan the
