Device and SwapChain (ArmA III nosteam) topic

Hi guys! I tried to take Device and SwapChain this way http://www.unknowncheats.me/forum/ar...m-overlay.html . But I can not understand how to determine what the offset is on the Device and SwapChain (I'm a noob in reverse).

I found the screen resolution, and I think that Device and SwapChain to be here too ... (gameoverlayrenderer.dll+978FC)

Tell me how to find the offset for Device and SwapChain.
