I'm assuming that you are using WinForms? What do you mean by "make a macro"?

You really need to give details about exactly what you want to test: a fixed area of the screen ?; a user selected area of the screen ?; a certain Control on a Form ? ... and so forth ...

Does your code trigger the test, or does some user-action trigger the test ?

Yes, of course. One of the ways to do it is using System.Drawing.Graphics.Graphics.CopyFromScreen:
