I could have avoided the exception in Listing 14-1 by checking whether the local variable was null. Although such checks are good practice, they are rarely applied consistently throughout a program, and not all exceptions are as easily avoided. There comes a point where you need to know how to deal with exceptions when they arise, and you do this using a try statement. Listing 14-2 demonstrates a simple use of a try statement. Listing 14-2. A Simple try Statement try { // try to so something with the local variable Console.WriteLine("First letter: {0}", myLocalVar[0]); } catch (NullReferenceException ex) { Console.WriteLine("Exception: {0}", ex.Message); } There are six parts to a basic try statement: the try keyword, the code statements, the catch keyword, the exception type, the exception identifier, and the handler statements. These six parts are illustrated in Figure 14-1.

How to protect PDF with password using C# , VB.NET | WinForms ...
12 Oct 2018 ... Steps to protect PDF with password programmatically: Create a new C# console application project. Install the Syncfusion. Pdf .WinForms NuGet package as reference to your .NET Framework application from NuGet.org. Include the following namespaces in the Program.cs file .

<validationErrorLabel targetElement="validator1" associatedControl="value1TextBox" /> <label targetElement="value1Label"> <bindings> <binding dataContext="value1TextBox" dataPath="text" property="text" /> </bindings> </label> </components> </page> </script> Most of this will look familiar, but you haven t seen a couple of new elements in here. First, a <textBox> control points to value1TextBox, which as you will see from the HTML is the <input> control. A new child element called <validators> is attached to this element. The <validators> tag can contain a number of validators that can be rangeValidator, requiredFieldValidator, typeValidator, rangeValidator, or regexValidator, among others. In this case, you are using a requiredFieldValidator, which fires an error if the field on which the validator is configured is empty. You specify the error message using the errorMessage attribute. A validation error needs to have a source on the page that it uses to represent the error to the user, or it will not be seen. In this example, you have a <span> that contains an asterisk that appears when an error occurs. To achieve this, you use the <validationErrorLabel> tag and associate it with this span. The span is called validator1, so the validationErrorLabel is given this as its targetElement. Finally, this validationErrorLabel needs to be tied to the control that it is the error message destination for, and you achieve this with the associatedControl attribute. Figure 5-11 shows this page after a validation error has been hit. You can see the red asterisk and the tooltip that appears when the user hovers over it. Note that you didn t have to write any code to make this asterisk appear or disappear, and you don t have to write explicit code for the tooltip. The Atlas framework handles all of this for you!

---Group Key - FirstChar: p, LengthGt5: True Item: persimmon Item: pineapple ---Group Key - FirstChar: l, LengthGt5: False Item: lemon Item: lime Press enter to finish You can see from the results that there are three groups in the results. Only groups that contain items are included in results. The fourth group that might exist in the results is omitted because there are no items that meet the group criteria (names that begin with l and have more than five characters).
