Traditional Zone OCR vs. Dynamic OCR - SimpleIndex - Document ...
Zone OCR is used to read document indexes or tags from text on the page. It is a great way to automate the data entry associated with scanning documents.

The problem is that although the Add() method can return an Integer with the value 60,000 (as this fits within the range of an Integer), the value cannot be stored in a Short (as it overflows the bounds of this data type). In this case, the CLR attempts to apply a narrowing operation, which resulted in a runtime error. As you can guess, narrowing is the logical opposite of widening, in that a larger value is stored within a smaller variable.

In other languages (especially C-based languages such as C#, C++, and Java) narrowing is termed an explicit cast.

Note At the time of this writing, Silverlight has a bug that affects how it deals with the Back button when using navigation. If you click the Back button to return to the initial page, you may receive a cryptic No XAML found at the location error message. Fortunately, it s easy to work around this problem by using the UriMapper to set the initial content of the frame, as described in the next section.

If n is not specified, all characters from position m to the end of the string are returned The first character in the string is position 1 For example, fn:substring("Money", 2, 3) returns "one" Returns the sum of the sequence of numbers in x For example, fn:sum( (1, 4, 9, 16, 25) ) returns 55 Returns the xs:boolean value true For example, fn:true() returns true..

Not all narrowing conversions result in a System.OverflowException of course. For example, consider the following code: ' This narrowing conversion is a-OK. Dim myByte As Byte Dim myInt As Integer = 200 myByte = myInt Console.WriteLine("Value of myByte: {0}", myByte) Here, the value contained within the Integer variable myInt is safely within the range of a Byte, therefore the narrowing operation does not result in a runtime error. Although it is true that many narrowing conversions are safe and nondramatic in nature, you may agree that it would be ideal to trap narrowing conversions at compile time rather than runtime. Thankfully there is such a way, using the VB 2005 Option Strict directive.

Sometimes you ll want to rotate a shape around a different point. RotateTransform, like many other transform classes, provides a CenterX property and a CenterY property. You can use these properties to indicate the center point around which the rotation should be performed. Here s a rectangle that uses this approach to rotate itself 25 degrees around its center point: <Rectangle Width="80" Height="10" Stroke="Blue" Fill="Yellow" Canvas.Left="100" Canvas.Top="100"> <Rectangle.RenderTransform> <RotateTransform Angle="25" CenterX="45" CenterY="5" /> </Rectangle.RenderTransform> </Rectangle> Figure 9-10 shows the result of performing the same sequence of rotations featured in Figure 9-9, but around the designated center point.

Option Strict ensures compile-time (rather than runtime) notification of any narrowing conversion so it can be corrected in a timely fashion. If we are able to identify these narrowing conversions upfront, we can take a corrective course of action and decrease the possibility of nasty runtime errors. A Visual Basic 2005 project, as well as specific *.vb files within a given project, can elect to enable or disable implicit narrowing via the Option Strict directive. When turning this option On, you are informing the compiler to check for such possibilities during the compilation process. Thus, if you were to add the following to the very top of your current file: ' Option directives must be the very first code statements in a *.vb file! Option Strict On you would now find a compile-time error for each implicit narrowing conversion, as shown in Figure 3-12.

fn:last()

Here, we have enabled Option Strict on a single file within our project. This approach can be useful when you wish to selectively allow narrowing conversions within specific *.vb files. However, if you wish to enable Option Strict for each and every file in your project, you can do so using the Compile tab of the My Project dialog box, as shown in Figure 3-13.
