Experience the Extensibility of Windows Forms

Overview of Part 3

Visual Studio .NET is a highly extensible development environment. Over 100 ISVs will be shipping new .NET versions of their tools and add-ons for Visual Studio .NET. You’ll find a special version of Crystal Reports integrated directly into the Visual Studio .NET IDE.

Crystal Reports fills an important role in the application development process by providing developers with a productive, integrated, and RAD experience for creating highly interactive relational data reports. These reports can be generated for the entire array of .NET application types, including XML Web services and Web-based solutions, as well as Windows-based applications running on desktop PCs and mobile devices.

Downhill Bikes management would like to enhance their application with a new reporting capability. The new report will enable them to drill into customer orders and look for trends in customer spending.

Proceeding with our tour, we will use Crystal Reports to extend our existing smart client with built-in reporting.




Part 3: Extend the Windows Form

Step 1 of 6: Add a new Visual Basic. NET Windows Form

We will add a second Windows Form to our project to contain the Crystal Report we build in the next step.

a. In the Solution Explorer, right-click WindowsApplication1, click Add, then click Add New Item… .

b. In the Templates pane, click the Windows Form icon and click Open (the default Name of Form2.vb is fine).

Step 2 of 6: Add a Crystal Report Viewer

The Crystal Report Viewer is integrated into Visual Studio .NET like the other rich controls in the toolbox. We will drag this report viewer to our form and use the new Windows Forms dock feature to automatically resize the report when we resize the form.

a. From the View menu, click Toolbox. CTRL+ALT+X

b. Click the Windows Forms tab in the toolbox.

c. Drag the Crystal Report Viewer (it’s at the bottom of the list) to the Windows Form designer surface. Make sure that the Crystal Report Viewer is selected in the designer.

d. From the View menu, click Properties Window. F4

e. From the Properties tool window, click Dock and press the letter F for Fill.

Step 4 of 6: Hook up the Report Viewer



In this step we will pass the data from the Web service to the Crystal Report. Crystal Reports was designed to integrate easily into Visual Studio .NET projects, so reports can reuse existing DataSets, relieving the developer from having to recreate their data access logic.

a. From the View menu, click Code. F7

b. Position the cursor on the empty line above End Class.

c. Double-click on the 3.4 Reporting code snippet in the Guided Tour toolbox.

b. Click Button2 to open the report.

c. Maximize the Form2 window.

Summary

In this step of the Guided Tour, you successfully incorporated a Crystal Reports viewer into the Downhill Bikes smart client application. This exercise illustrates the power of the Visual Studio .NET extensibility model by showing how third-party tool and language vendors can seamlessly integrate their products directly into Visual Studio .NET.

In the next step of the Guided Tour, we’ll delve into Web application development and the use of Application Center Test to analyze the load performance of our Web applications.
