Printing pdf417 in visual C# Commonly Used Classes and Interfaces in Csla.Core

Since this is the first business class to be created, I ll walk through the code in complete detail. You can assume that subsequent classes follow a similar structure overall. The Project class will use a number of .NET and CSLA .NET features. To make this easier, a number of namespaces are imported at the project level (through the References tab in the My Project designer). These include: System.Data System.Data.SqlClient Csla Csla.Data These references are used to simplify the code in the class. For instance, the data access code will interact with SQL Server, so the project needs to import the System.Data.SqlClient namespace. And of course, CSLA .NET features are used, so namespaces are brought in for that as well. The class itself is contained within the default ProjectTracker.Library namespace and is declared as follows: <Serializable()> _ Public Class Project Inherits BusinessBase(Of Project)

Figure 8-4. Style overriding example In this example, we defined styles in Grid.Resources. However, it is best practice to define global styles at the application level by defining them in App.xaml. In that case, the code to reference such styles will look like this:

Summary

(Name)

Font normalFont = Resources.GetFont(Resources.FontResources.NinaB); Font smallFont = Resources.GetFont(Resources.FontResources.small); // Create a list box control and add text items ListBox listBox = new ListBox(); // set the width so that it fills the entire screen listBox.Child.Width = mainWindow.Width; // make the list box transparent listBox.Background = null; // make the enclosed scroll viewer transparent also // we get the scroll viewer via the child property but // need to cast it to Control in order to clear the background ((Control)listBox.Child).Background = null; // Add simple text items for (int i = 0; i < 2; ++i) { string str = "Simple text item"; Text text = new Text(normalFont, str); text.SetMargin(2); ListBoxItem item = new HighlightableListBoxItem(text); listBox.Items.Add(item); } // Add a separator listBox.Items.Add(new SeparatorListBoxItem()); // Add a text item with icon { // Create the stack panel to align the elements StackPanel stackPanel = new StackPanel(Orientation.Horizontal); // Icon Bitmap bmp = Resources.GetBitmap(Resources.BitmapResources.Clock); // Make the bitmap transparent using // the color of the top left corner pixel. // Therefore the image should not be in the Bitmap and Jpeg format // because that requires to create a copy in order to make it // transparent. Use Gif instead. bmp.MakeTransparent(bmp.GetPixel(0, 0)); Image image = new Image(bmp); image.SetMargin(2); // set a margin to separate the image // vertically center the icon within the item image.VerticalAlignment = VerticalAlignment.Center; stackPanel.Children.Add(image);

If you were to broadly characterize the source code of C and C++ programs, you might say that a C program is a set of functions and data types, and that a C++ program is a set of functions and classes. A C# program, however, is a set of type declarations. The source code of a C# program or DLL is a set of one or more type declarations. For an executable, one of the types declared must be a class that includes a method called Main. A namespace is a way of grouping a related set of type declarations and giving the group a name. Since your program is a related set of type declarations, you will generally declare your program inside a namespace you create. For example, the following code shows a program that consists of three type declarations. The three types are declared inside a new namespace called MyProgram. namespace MyProgram { DeclarationOfTypeA DeclarationOfTypeB class C { static void Main() { ... } } } Namespaces will be covered in more detail in 10. // Create a new namespace. // Declare a type. // Declare a type. // Declare a type.

WSE 3.0 allows developers to become early adopters of the next generation of service-oriented application technology. Every hour that you spend working with WSE 3.0 is an hour that you have contributed toward WCF. Applications that are built using WSE should migrate smoothly to the WCF framework, with only minor modifications required. If you choose to implement WSE today, then you should expect to accommodate changes to WSE between now and the release of WCF. It is unclear how many revisions WSE is expected to undergo prior to the release of WCF, but it is likely that we will only see service packs released, and they are not expected to negatively impact compatibility between WSE 3.0 and WCF. If anything, they should only make the compatibility tighter. Table 9-3 compares the feature set of WSE 3.0 with WCF, based on current information provided by Microsoft.

lthough you can create complex pivot tables without programming, some pivot table settings can only be changed by using programming. As a developer, you can use programming to limit the ways users can manipulate your pivot tables, or to simplify a complex set of tasks. For example, you can provide a button on the worksheet that users can click to format, refresh, and preview a pivot table before printing. This chapter addresses programming issues related to pivot tables and provides code examples for macros that can t be recorded. The chapter begins with a brief introduction to using Excel s macro recorder and the Visual Basic Editor (VBE), where you can view and edit the code stored in the workbook s modules. Many excellent books are available with instructions and examples for learning how to program in Excel. Also, extensive documentation is in the VBE help files and Excel s help files. For an overview of the Excel 2007 object model, see Excel Object Model Reference on the Microsoft web site at http://msdn2.microsoft.com/en-us/library/bb332345.aspx. Except where noted, the problems in this chapter are based on the Sales11.xlsm workbook. The code, in text format, is also available in the file named Code.txt. You can copy the code from the text file into your own workbooks, or experiment with the code in the sample workbooks.
