Teach yourself how to build applications with Microsoft Visual C# 2012 and Visual Studio 2012—one step at a time. Ideal for those with fundamental programming skills, this tutorial provides practical, learn-by-doing exercises for mastering core C# language features and creating working applications and components for Windows.
Discover how to:
- Work with variables, non-reserved identifiers, statements, operators, and methods
- Use the new application models provided by Windows 8 and the Windows Runtime
- Create interfaces and define abstract classes
- Manage errors and exception handling
- Use collection classes
- Work with databases by using DataBinding with the Entity Framework
- Respond to user input and gestures; gather input from devices and other sources
- Handle events arising from multiple sources
- Develop your first Windows 8 apps

provides a more convenient way for you to modify the properties for items on a form, as well as other items in a project. The Properties window is context sensitive in that it displays the properties for the currently selected item. If you click the form displayed in the Design View window, outside of the TextBlock control, you can see that the Properties window displays the properties for a Grid element. If you look at the XAML pane, you should see that the TextBlock control is contained within
when the first date is earlier than the second date. 17. Test some other dates, and verify that the results are as you would expect. Return to Visual Studio 2012 and stop debugging (or close the application if you are using Windows 7) when you have finished. Comparing Dates in Real-World Applications Now that you have seen how to use a rather long and complicated series of if and else statements, I should mention that this is not the technique you would employ to compare dates in a real-world
and not part of an XML instruction. Similar rules apply to the right angle bracket (>), ampersand (&), single quotation mark ('),and double quotation mark (") characters. You will write a switch statement that tests the value of the character and traps the special XML characters as case labels. 110 PART I Introducing Microsoft Visual C# and Microsoft Visual Studio 2012 Write switch statements 1.

is on the while condition at the end of the do loop: while (amount != 0); As the value of amount is now 0, the expression amount != 0 evaluates to false, and the do loop should terminate. 22. Click Step Into. The debugger runs the statement while (amount != 0); As predicted, the do loop finishes, and the yellow arrow moves to the closing brace at the end of the showStepsClick method.

another way to handle this situation in Chapter 14, “Using Garbage Collection and Resource Management.” Summary In this chapter, you learned how to catch and handle exceptions by using the try and catch constructs. You saw how to enable and disable integer overflow checking by using the checked and unchecked keywords. You learned how to throw an exception if your code detects an exceptional situation, and you saw how to use a finally block to ensure that critical code always runs, even if an
