Automatically getting the X coordinates of a screen?

[merp.]

As the title states, how would I be able to get the X coordinates of a screen? (When it resizes?)

Ex: when I am at the login screen, my Screensize is 1366x768 (Black bars at both sides, so my screen is affected).
but when I am in game, my screensize goes back to my default, 1600x900. I would like to be able to get the X coordinate when the screen resizes so that I when I a draw a box using DrawBox, it'll stay in the same place.

ex1:
DrawBox(400, 20);// just the x + y coords. (random coords)
If I were to draw this box in 1366 x768 size, it would be where I want it.

However, if I were to use this once again in 1600 x900 size, the box would be in the wrong place.


How would I be able to get the X coordinates automatically, so that if the screen resizes, it would be in the same place, no matter what?
I got the width of the box to automatically fit the size using the cScreenInfo class @Flengo uploaded. (Thank you!)

D3DVIEWPORT9 Viewport;
pDevice->GetViewport(&Viewport);
DWORD ScreenX = Viewport.Width / 2;
DWORD ScreenY = Viewport.Height / 2;

A.scale_x = ScreenX / bmap_width(A.bmap);
A.scale_y = ScreenY / bmap_height(A.bmap);

Not that hard

My example for ReClass wasn't really something "useful" to be used. The method posted above is actually what I use to get screen resolution.

My tutorial was just an example to get used to ReClass.

I have my X-hairs calibrating from the screen resizing, I'm not exactly sure how I did it >.< it was like from 2 years ago and I haven't touched it since.

or cursor center?

#define ADDR_CURSORCENTER 0x00805D2C //Found at: 0x00505D23 ( Engine.exe[0x00460000] + 0x000A5D23 )

Or am I thinking of a completely wrong thing here?

This address is a byte or boolean (1byte of size)
If its 1, cursor is locked in middle of screen, else its free moveable
