Read screen without injecting?

Basically, I want to create a program in c++/C# that can read data off screen without injecting any DLL. I want to read for example a timer in a windowed game (As far as I know it won't work on full screen) without injecting anything, the game is hack protected. I am not trying to hack it, just to build an addon :)

Thx for your time,

There are probably 3 ways of getting information about what another process is doing:
- by injecting code/dlls
- by using [Only registered and activated users can see links. Click Here To Register...] or
- by getting some pixels of the screen with [Only registered and activated users can see links. Click Here To Register...]

With you know-how it is impossible.

Cheers!

GetPixel is often blocked, because this is a typical way for a Pixel-Bot.

But there are other ways that are used from the screen video software that normaly works. ( So people can create ingame videos )

Take a look into this thread:
[Only registered and activated users can see links. Click Here To Register...]

It contais the Source-Code for a C# Pixel Bot.
The Kernal Driver is blocked in the meantime , but huge parts of the code shoud still work.
