The problems with multiple Undo are not due to its behavior as much as they are due to its manifest model. Most Undo facilities are constructed in an unrelentingly function-centric manner. They remember what a user does function by function and separate her actions by individual function. In the time-honored way of creating manifest models that follow implementation models, Undo systems tend to model code and data structures instead of user goals. Each click of the Undo button reverses precisely one function-sized bite of behavior. Reversing on a functionby-function basis is a very appropriate mental model for solving most simple problems that arise when a user makes an erroneous entry. The mistake is noticed right away and the user takes action to fix it right away, usually by the time he s taken two or three actions. However, when the problem grows more convoluted, the incremental, multiple-step Undo model doesn t scale very well.

When a user goes down a logical dead end (rather than merely mistyping data), he can often proceed several complex steps into the unknown before realizing that he is lost and needs to get a bearing on known territory. At this point, however, he may have performed several interlaced functions, only some of which are undesirable. He may well want to keep some actions and nullify others, not necessarily in strict reverse order. What if he entered some text, edited it, and then decided to Undo the entry of that text but not Undo the editing of it Such an operation is problematic to implement and explain. Neil Rubenking offers this pernicious example: Suppose that a user did a global replace changing tragedy to catastrophe and then another changing cat to dog. To Undo the first without undoing the second, can the program reliably fix all the dogastrophes In this more complex situation, the simplistic representation of the Undo as a single, straight-line, LIFO stack doesn t satisfy the way it does in simpler situations. The user may be interested in studying his actions as a menu and choosing a discontinuous subset of them for reversion, while keeping some others. This demands an explanatory Undo with a more robust presentation than might otherwise be necessary for a normal, blind, multiple Undo. Additionally, the means for selecting from that presentation must be more sophisticated. Representing the operation in the queue to show the user what he is actually undoing is a more difficult problem.

Observation angle (deg)

The Redo function came into being as the result of the implementation model for Undo, wherein operations must be undone in reverse sequence, and in which no

operation may be undone without first undoing all of the valid intervening operations. Redo essentially undoes the Undo and is easy to implement if the programmer has already gone to the effort to implement Undo. Redo prevents a diabolical situation in multiple Undo. If a user wants to back out of a half-dozen or so operations, he clicks the Undo control a few times, waiting to see things return to the desired state. It is very easy in this situation to press Undo one time too many. He immediately sees that he has undone something desirable. Redo solves this problem by allowing him to Undo the Undo, putting back the last good action. Many programs that implement single Undo treat the last undone action as an undoable action. In effect, this makes a second invocation of the Undo function a minimal Redo function.

The Main method is the entry point for any NET application In Visual StudioNET 2003, this was always placed in the first Form class added to a project In Visual Studio 2005, the Program class is added to the project as a separate code file so that the Main method doesn't get lost if the first form is deleted from the project We will mirror that approach here, but just put it in the same file for simplicity The STAThread attribute is needed if the application will use any ActiveX controls, the Clipboard, or any single-threaded apartment COM objects, so it is added by default to any Visual Studio Windows application projects, and in general, you always need it there You need to bring in the System namespace with a using statement to make that attribute type available
