Well i never was the one who said it would be fast smile
Also didnt realize you were after realtime tracking of soemthng small,
I thought it was more a need to pull the pixel colors of another screen off, like u wanted to build the whole picture (or part of) up in something else, then it would have been fine, just screen cap, drop the whole bmp in a picwin and cut out the chunk u want.

Im sure some of the dll writers around could bang up soemthing that well access the screen x,y direct and return a pixel color, but im not one of them,

(/me is to lazy to sort out why .net wouldnt work with mirc when i tried, and never tried again)
