Why would you expect them to remain the same in a game that is running?
I have no idea what game you are trying to cheat, but you are reading the memory of a different process, so it will get run, stopped, loaded, unloaded, cached, paged to disk, and generally have a hard life - all at the whim of the operating system. Add in that the game itself will probably be moving stuff around as it runs to suit itself, and the chances of you finding exactly what you want without the source code to work form is very unlikely. And that is assuming that you have identified the actual linked list, rather than some stack based object that temporarily looked like an element that might be on a linked list, if the code actually used one.
So why would you expect everything to stay in the same place for your convenience?

Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...

If you have to ask this, then I doubt that the address you're reading is what you think it is. Not to mention what it points to. Every process uses it's own mapping from it's address space to the underlying physical addresses, and the system functions take care that each address used within a process is mapped accordingly: to some location within the momry space that is associated to this, and only this, process!
Consequently, a process can never access memory from another process, unless the two processes are set up specifically for that purpose: the only way I know to read memory from another process is setting up shared memory. And I doubt that your game allows this.
Take this with a grain of salt and a big AFAIK - I'm anything but a specialist on this topic
GOTOs are a bit like wire coat hangers: they tend to breed in the darkness, such that where there once were few, eventually there are many, and the program's architecture collapses beneath them. (Fran Poretto)
Anything you type into a text box is a string, whether letters, numbers or special characters. If you want to use numeric text as integer values then you need to convert them with one of the conversion methods. See Data Conversion | Microsoft Docs[^].
SQl is not greater than 1000. I wanted to create a simple application first. Like for example.. I have a table with ID(primary Key), Name, DOB...etc columns.
What I wanted to create is a search box in the dialog application. when I type the Name in the search box it will display the result in the listbox/list control box. Similarly when I enter the ID in the search box it will return the same.
Confidence that I have solved all strange errors here, I come back with some issue generated by a legacy C code for linux, code that I intend to use it in a MFC app in windows OS.
Ok. I have a simple code:
int nRespond = _open(device, 020);
UINT err = ::GetLastError();
where devide is const char* and has value C (or D:, or E: )
The nRespond is -1 and err has value 5, which is mean Access is denied. What could be the problem here ? I ran the test app as administrator mode (ran from VS2017 as admin mode).
The problem appears to be that you are expecting Linux code to work on Windows. The _open function opens a file - on unix systems you can open directories and devices as files, but not on Windows.
If you're lucky the code is actually expecting a normal file and you just passed in a device letter by mistake. Otherwise you will have to port the code, replacing the Linux system functions with code that does the same thing on Windows.
