Notice how the format specifier is passed directly to ToString( ) Unlike embedded format commands used by WriteLine( ) or Format( ), which supply an argument-number and fieldwidth component, ToString( ) requires only the format specifier, itself

2 mx = - mAw n cos(w n t + f ) = - kA cos(w n t + f )

TABLE 4-3

Part II:

Here is a rewrite of the previous format program that uses ToString( ) to obtain formatted strings It produces the same output as the earlier versions

.

(115)

// Use ToString() to format values using System; class ToStringDemo { static void Main() { double v = 1768865849; double v2 = 015; int x = 21; string str = vToString("F2"); ConsoleWriteLine(str); str = vToString("N5"); ConsoleWriteLine(str); str = vToString("e"); ConsoleWriteLine(str); str = vToString("r"); ConsoleWriteLine(str); str = v2ToString("p"); ConsoleWriteLine(str); str = xToString("X"); ConsoleWriteLine(str); str = xToString("D12"); ConsoleWriteLine(str); str = 18999ToString("C"); ConsoleWriteLine(str); } }

Although the predefined numeric format specifiers are quite useful, C# gives you the ability to define your own, custom format using a feature sometimes called picture format The term picture format comes from the fact that you create a custom format by specifying an example (that is, a picture) of how you want the output to look This approach was mentioned briefly in Part I Here it is examined in detail

Also, realize that in some circles and with some user segments, these individual product names may have meaning and recognition Many users, however, may have never heard of them In this respect, you will have to repeat, within your own organization, all the selling Business Objects, the company, had to go through to persuade you to buy their tool set As you do so, focus as much as possible on the benefits your implementation will deliver, not the technical features of the products Consider some of the products you buy as a consumer For example, Disney World emphasizes the magic and memories (the benefits), not the number of rides and attractions (the features) Particularly with business intelligence, a number of technical features will have little meaning to users, yet clearly, IT professionals are comfortable focusing on features Restating the features in terms of the benefits is one of the hardest language barriers for the project team to overcome Table 4-4 highlights some features that are better described to users in terms of the benefits they provide In a few instances, the feature and related benefit will be clear; but these instances are in the minority For example, if you emphasize the ability to create graphs, spreadsheet users who have used graphs in their analysis will recognize that graphs provide the benefit of visual analysis and a faster ability to spot trends, problems, and opportunities When you buy a car, you know that four-wheel or front-wheel drive (feature) will allow you to control your car better in snow (the benefit) When the benefit is not immediately clear, document it as part of your project plan Then have the project team practice articulating the benefits so that they (1) stay focused on why you are implementing BusinessObjects XI and (2) can more effectively promote your efforts in both formal and casual conversations with users A second aspect to the product component of the market mix is what to call the product Will you refer to it by the vendor-provided product names, or will you give it a different.

The frequency of oscillation, or natural frequency, is thus given by wn = k m (116)

When you create a custom format, you specify that format by creating an example (or picture) of what you want the data to look like To do this, you use the characters shown in Table 22-6 as placeholders Each is examined in turn

in units of radians/second Note that this formula works directly when the stiffness and mass are in SI units (N m and kg, respectively), but when English units of lbf/in and lbm are used a conversion is necessary w n = 322 12 k m (117)
