No it's not

I don't really know much about C++ and how memory addresses work ( never studied C++ "hard", I'll start soon ) but here's the memory address & some info that I got from GTAModding:

0xBA6820 - [byte] Resolution values: 
  
    11 = 640x480 
    12 = 800x400 
    13 = 800x600 
    15 = 1024x768  

If you know C++ and how to manage with memory addresses, then it should be easy for you to get resolution with this.

You could read the XML values of the config file.
