Quản lý Breakpoints Theo thời gian, điểm dừng có thể được đặt trên nhiều địa điểm trong dự án của bạn. Bạn có thể quản lý tất cả các điểm dừng tại một vị trí trung tâm bằng cách chọn Debug | Windows | Breakpoints, mà sẽ hiển thị các cửa sổ trong hình 6-7. Phần lớn các chức năng của cửa sổ Breakpoints đã được giải thích đã có, ngoại trừ các tùy chọn thanh công cụ áp dụng cho tất cả các điểm ngắt hiện đang kiểm tra. | 158 Microsoft Visual Studio 2010 A Beginner s Guide Figure 6-7 The Breakpoints window Managing Breakpoints Over time breakpoints can be set across many locations in your project. You can manage all of these breakpoints in a central location by selecting Debug Windows Breakpoints which will show the window in Figure 6-7. Much of the functionality of the Breakpoints window has been explained already except that the toolbar options apply to all of the breakpoints that are currently checked. Clicking a column sorts the contents. The Search box helps you filter breakpoints and the In Columns box helps focus on what the search applies to. There are export and import buttons on the toolbar that allow you to respectively save and retrieve breakpoints to and from an XML file. Double-clicking any breakpoint takes you to the location in the editor where the breakpoint is set. Right-clicking a breakpoint shows a context menu with options that have already been discussed in this section. Once you set a breakpoint you can step through code to see what the execution flow of the program is as is discussed in the next section. Stepping Through Code Stepping through code is the process of executing one or more lines of code in a controlled manner. At the most granular level you can step through code line-by-line. While moving line-by-line is often necessary it could also be cumbersome so there are ways to step over multiple lines of code allowing them to silently and quickly execute. To step through code open a project set a breakpoint and run with debugging until the program hits the breakpoint. At that point in time you can perform various operations such as step step over and step out. Table 6-2 explains the stepping operations that are available. The explanations in the table assume that a breakpoint has been hit with your executing program now paused before performing the step operation.
