The solution is summarized initially in conjunction with the problem. It is also described in detail often using UML class and interaction diagrams. The pattern usually includes a code example. Although code may be presented, the solution is never cut and paste. The pattern describes an approach to a problem. There may be hundreds of nuances in implementation. Think about instructions for sowing a food crop. If you simply follow a set of steps blindly, you are likely to go hungry come harvest time. More useful would be a pattern-based approach that covers the various conditions that may apply. The basic solution to the problem (making your crop grow) will always be the same (plant seeds, irrigate, harvest crop), but the actual steps you take will depend on all sorts of factors such as your soil type, your location, the orientation of your land, local pests, and so on. Martin Fowler refers to solutions in patterns as half-baked. That is, the coder must take away the concept and finish it for himself.

If you forget what names you have already used or which cell or cell range they apply to, you can view a dialog box that shows all the defined names within the current workbook by clicking the Name Manager button. Figure 8-5 shows an example of the Name Manager.

int This = 10; int That = 16; int* IntPointer = &This; *IntPointer = That has the same effect as saying This = That. If you set IntPointer = &That, then *IntPointer = 47 has the same effect as saying That = 47. Pointer arithmetic is by element size, not by bytes: *(++Ptr) steps Ptr and dereferences the next element, whether that is a single byte, or a multibyte number or character, or a multibyte struct. *(FloatPtr+11) += 1 increments the twelfth float in an array (or, at least, the eleventh float ahead of the current FloatPtr).

Caution Pointer arithmetic is not range checked. It is fast, but it is unsafe. Errors in unsafe code can

C# tutorial: Add annotations to an existing PDF
To add the text annotation to the PDF document, you need to create an instance of PdfReader class to read pages from the PDF source file. Then create an instance of the PdfStamper class. Then use the AddAnnotation method of the PdfStamper class. This method has two arguments: the PdfAnnotation object and page number.

Figure 8-5. The Name Manager shows all named cells and ranges. You can also use the Name Manager to edit properties of a name or delete a name. You can even create a new name definition by clicking the New button. Ideally, you should define named cells that you want to use as parameters before you begin creating your spreadsheet. A good practice groups these parameter cells in a single place, perhaps at the top of the spreadsheet as shown in this example, or on a different worksheet dedicated to only prompting for parameters. Then as you lay out the rest of your spreadsheet, you can reference the named cells and named cell ranges in your formulas rather than using cryptic cell references.

Every design decision you make will have wider consequences. This should include the satisfactory resolution of the problem in question, of course. A solution, once deployed, may be ideally suited to work with other patterns. There may also be dangers to watch for.
