In the real world, the most sensible use for the AdWords API is to integrate with systems that manage massive amounts of advertising. It makes sense to create custom
AdWords API web service code if you are managing thousands of campaigns, ads, and keywords—on your own account or as an ad agency on behalf of clients.
Complex inventory systems that automatically publish AdWords ads when inventory items meet certain criteria—and revise these ads when an item goes out of stock—are also good candidates for automated interaction with the AdWords API.
In either of these cases, or to program any application that interacts with existing
AdWords objects, you need to know how to navigate the hierarchy of existing
AdWords objects in code. Starting with the authentication information for an account, you can programmatically access campaigns, ads, and the elements that make up ads (such as keywords).
This chapter shows you how to work your way from account information to campaign to AdGroup level, getting as granular as you’d like, all using C# and Visual
“Mirrors should reflect a little before throwing back images.”
Freud's definition of the aim of reality-testing, as expressed in his paper on “Negation”, is well known: “… not to find an object in real perception which corresponds to the one presented, but to re-find such an object …” (1925h, p. 237).
This definition does not involve the “apparatus” the task of which is to differentiate between hallucination and perception, internal world and external world, corresponding to the principle of judgement of existence (which in itself is not without problems). It refers to the function of comparison between the perceived object and the object as presented, so that adjustments can be made if it proves to be distorted. This is “testing” in the true sense of the word, much more than in the first case described by Freud: something is being put to the test, and thanks to this, the work of mourning can proceed—the work of modifying the internal world to take account of a loss in reality.
Sure, you can sometimes get perfectly good results using your camera set on automatic exposure mode. But, of course, using auto exposure substitutes a calculation made by the processor inside your camera for your own creative judgement. Sometimes there’s no substitute for manually choosing your exposure components.
Purists will say that if you want to take those great photos you see in your mind’s eye, you’ve got to get your camera off automatic exposure. In part, this is because getting your camera off auto does mean understanding exposure. Great photos start with good exposures
(even if these exposures are later enhanced in the digital darkroom). These purists (and I) do want you to understand exposure.
Even the purists know that it sometimes makes sense to use one of the semi-automatic exposure modes that
I’ve already mentioned in passing.
As opposed to a fully automatic exposure mode, in a semi-automatic mode you choose one of the components of the exposure equation (such as shutter speed or aperture), and the camera makes the rest of the settings.
