As an aside, figure 1.6 exposes a problem with our application that will need to be fixed. Since the image scales along with our PictureBox control, the aspect ratio changes as well. The aspect ratio is the ratio of the height of an image to its width. A standard 4-inch by 6-inch photograph, for example, has an aspect ratio of two-thirds (4 divided by 6). As the form is resized the image is distorted to fit the control, which affects the aspect ratio. We will fix this in chapter 7. In the meantime, keep in mind that our program exhibits what can only be called a bug. While we have only added three lines here, they lead us to some interesting discussion points. 1.4.1 Desktop layout properties The first change in our program sets the MinimumSize property to define the minimum possible size for the form. This ensures that the form never becomes so small that the PictureBox disappears and our image cannot be seen. The MinimumSize property is a Size structure representing the minimum width and height of the form. As you may recall, structures are value types and store their data directly, either on the stack or as part of the containing type. As we discussed in section 1.1.3, the new keyword is used to create a new value type. When one value type is assigned to another, as we do here, the contents of the original type are copied into the target type. As a result, the fact that the newly allocated Size structure is destroyed when the MyForm constructor is finished has no effect on the value stored within the MyForm class.

Here s a sample development schedule for a hypothetical 18-month project Let s say that we re going to make a console game with a license of some kind Pro Linebacker Barbie , or something of the sort We ll have to include extra time in the schedule for the license holder and console manufacturer to check over and approve the product We ll also assume that this is an English-only game, so it doesn t require localization This example does not include the marketing or sales effort, which is, of course, going on in parallel with development Suppose we pick a ship date of November 15, 2005 in other words, in time for the holiday shopping season We ll want to leave a month of lead time for the console company to manufacture the games for us, because a lot of other publishers are having their games manufactured around then, too (Cartridge games for machines like the Game Boy Advance actually require longer than this; for disc-based games it s often less, especially at other times of the year) That sets our actual gold master date at October 15, 2005 Therefore, for an 18-month project, we ll need to start on April 15, 2004 April 15, 2004: Pre-production begins A small team is doing concept design, technical research, and prototyping work They re also building the tools they will use during full production July 15, 2004: Conceptual design complete; partially playable prototype Three months into the project, the designers will have written a thorough design script The programmers will use it as a requirements document to create a technical design for the final product October 15, 2004: Full production begins Technical design complete; tools complete; playable prototype Using the prototype, the designers can see how the game s mechanics are working and fine-tune as necessary The team staffs up to full strength During full production, there will be numerous milestones to make sure the project is on track Since these vary with the actual nature of the code and content, I haven t included them here April 15, 2005: Formal testing begins Although the game isn t complete yet, the producers have been testing parts of it all along Now, a testing manager assembles a test plan and assigns a limited number of testers to begin work on the parts of the game that are finished.
