  1. Chapter 1 Getting Started with VB .NET and Crystal Reports Debbie St. GeorgeWonder Ranch Publishing DBA/ProgrammerCovington Visual Studio.Net User Group

  2. Objectives • Create a simple Crystal Report in Visual Studio.NET • Display a Crystal Report in a Windows Forms Application • Display a crystal Report in a Web Forms Application • Publish a Crystal Report as an XML Report Web Service • Deploy Crystal Reports to the Web

  3. Crystal Report Advantages • Some of the major advantages of using Crystal Report for Visual Studio .NET are : • - Rapid report development • - Can extend it to complicated reports with interactive charts • - Exposes a report object model using which it can interact with other controls on the web form • - Can programmatically export the reports into widely used formats like .pdf, .doc, .xls, .html and .rtf

  4. Information Delivery Infrastructure is the Key

  5. Architecture in Detail… Based on Standards Supports Existing Data Sources Accessible by All Users Delivered the Way User’s Want to Use Data

  6. Crystal Reports Walkthrough - using the Pull Model Add a New Project to the Solution.Project… Add Item… Crystal Decisions Window App

  7. Add a Crystal Report:Go to Project.. Add New Item..Web Project Items..Crystal Report Keep the CrystalReport1.rpt as the default name for this report. Click Open and you will get the Crystal Report Gallery Dialog.

  8. Select standard report

  9. Select OLE DB (ADO) Microsoft Jet 4.0 OLE DB Provider

  10. Adding data and fields

  11. Group and Total

  12. Top N and Chart Data

  13. Standard Report Design

  14. Crystal Report

  15. Add Crystal Report Viewer to Form1.vb

  16. Right-click on Form1 and View code. type Text in yellow areas.

  17. Build and then run the report

  18. Add Project.. new project…ASP.net web application

  19. Right-click and set form as startup form. Project as startup project.

  20. From an existing report

  21. Add previously created CrystalReport1

  22. Add code behind webformBuild..Build SolutionDebug.. Start without debugging

  23. Run from the web.

  24. As an Asp.Net Web Service

  25. Add crystalreport1

  26. Testing CrystalReport1Service

  27. Right-click on Crystal Report and set as Startup

  28. Right-Click on Form1.vb and Select View Code

  29. Change ReportSource to our Web Service .asmx

  30. Web Form hosted in Windows Environment

  31. Add CR Deployment Project Crystal Reports Deployment Steps:* Create a Web Setup Package * Defining required runtime components

  32. Web Setup Project(Note: Setup is the same for a Win Project)

  33. From WebSetup (add Merge Modules)

  34. Deploy Crystal Reports Report files (.RPT) need to be distributed when a .NET application is deployed. Merge Modules CR for VS .NET provides merge modules in setup projects to make deployment a simple task. The merge modules are installed to the following folder, by default: C:\Program Files\Common Files\Merge Modules\ There are four merge modules that need to be included in a setup project to deploy reports. • Managed.MSM • Database_Access.MSM • Database_Access_enu.MSM • REGWIZ.MSM

  35. RegWiz.msm Needs Lic Key

  36. Registering Crystal Report ProductHttp://www.crystaldecisions.com/register.Content.asp

  37. Resources • Crystal Decisions Websitehttp://www.crystaldecisions.com/products/dev_zone/default.asp • Free ASP.NET Web Matrix http://www.asp.net/webmatrix/default.aspx?tabindex=4&tabid=46 • The XML for ASP.NET Developers Website Video Tutorialshttp://www.xmlforasp.net/ • http://www.aspfree.com/authors/jitajay/crystalreport.aspx

  38. Passing a Stored Procedure to a Report NOTE: This sample Windows application uses the Windows Forms viewer. The sample has one form (Form1) that contains the viewer. The report code is run from the form's constructor (Public Sub New( )). ==================== Imports CrystalDecisions.CrystalReports.Engine Imports CrystalDecisions.Shared Public Class Form1 Inherits System.Windows.Forms.Form 'Crystal Reports Variables Dim oRpt As New CRStoredParam() Dim crTables As Tables Dim crTable As Table Dim crTableLogOnInfo As TableLogOnInfo Dim crConnectionInfo As New ConnectionInfo() Dim crParameterValues As ParameterValues Dim crParameterDiscreteValue As ParameterDiscreteValue Dim crParameterFieldDefinitions As ParameterFieldDefinitions Dim crParameterFieldDefinition As ParameterFieldDefinition

  39. Passing a Stored Procedure to a Report (cont) #Region " Windows Form Designer generated code “ Public Sub New() MyBase.New() 'This call is required by the Windows Form Designer. InitializeComponent() 'Add any initialization after the InitializeComponent() call ' Set the Connection parameters ' Using an OLEDB connection to a SQL Sever DB (Database: Pubs) With crConnectionInfo .DatabaseName = "DBName“ .ServerName = "ServerNameOrODBCName“ .UserID = "UserID“ .Password = "Password“ End With crTables = oRpt.Database.Tables 'Set the logon information for each table. For Each crTable In crTables crTableLogOnInfo = crTable.LogOnInfo crTableLogOnInfo.ConnectionInfo = crConnectionInfo crTable.ApplyLogOnInfo(crTableLogOnInfo) Next

  40. Passing a Stored Procedure to a Report (cont) ' Pass the Stored Procedure parameter to the report 'Get the collection of parameters from the report crParameterFieldDefinitions = oRpt.DataDefinition.ParameterFields 'Access the specified parameter from the collection crParameterFieldDefinition = rParameterFieldDefinitions.Item("@percentage") 'Get the current values from the parameter field. At this point 'there are zero values set. crParameterValues = crParameterFieldDefinition.CurrentValues 'Set the current values for the numeric parameter field crParameterDiscreteValue = New ParameterDiscreteValue() crParameterDiscreteValue.Value = "50" 'Add the current value for the parameter field crParameterValues.Add(crParameterDiscreteValue) 'The current parameter values must be applied for the parameter field. crParameterFieldDefinition.ApplyCurrentValues(crParameterValues) CrystalReportViewer1.ReportSource = oRpt End Sub #End Region End Class

  41. 1. Create a Dataset during design time. 2. Create the .rpt file (from scratch) and make it point to the Dataset that we created in the previous step. 3. Place a CrystalReportViewer control on the .aspx page and set its properties to point to the .rpt file that we created in the previous step. 4. In your code behind page, write the subroutine to make the connections to the database and populate the dataset that we created previously in step one. 5. Call the Databind method from your code behind page. CRYSTAL REPORTS WALKTHROUGH – USING THE PUSH MODEL(Objectives)

  42. Creating a Dataset during Design Time to Define the Fields of the Reports1. Right click on "Solution Explorer", select "Add" --> select "Add New Item--> Select "DataSet"

  43. 2) Drag and drop the "Stores" table (within the PUBS database) from the "SQL Server" Item under "Server Explorer".

  44. 3) This should create a definition of the "Stores" table within the DatasetNote:The .xsd file created this way contains only the field definitions without any data in it. It is up to the developer to create the connection to the database, populate the dataset and feed it to the Crystal Report .

  45. Creating the .rpt File : • 4) Create the report file using the steps mentioned previously. The only difference here is that instead of connecting to the Database thru Crystal Report to get to the Table, we would be using our DataSet that we just created. • 5)After creating the .rpt file, right click on the "Details" section of the Report file, select "Add/Remove Database" • 6) In the "Database Expert" window, expand "Project Data" (instead of "OLE DB" that was selected in the case of the PULL Model), expand "ADO.NET DataSet", "DataSet1", and select the "Stores" table.

  46. 7) Include the "Stores" table into the "Selected Tables" section by clicking on ">" and then Click "ok"

  47. 8) Follow the remaining steps to create the report layout as mentioned previously in the PULL Model to complete the .rpt Report file creation Creating a CrystalReportViewer Control 9) Follow the steps mentioned previously in the PULL Model to create a Crystal Report Viewer control and set its properties.

  48. 48Code Behind Page Modifications : • 10) Call this subroutine in your page load - • Sub BindReport() • Dim myConnection As New SqlClient.SqlConnection() • myConnection.ConnectionString= "server= (local)\NetSDK;database=pubs;Trusted_Connection=yes" • Dim MyCommand As New SqlClient.SqlCommand() • MyCommand.Connection = myConnection • MyCommand.CommandText = "Select * from Stores" • MyCommand.CommandType = CommandType.Text • Dim MyDA As New SqlClient.SqlDataAdapter() • MyDA.SelectCommand = MyCommand • Dim myDS As New Dataset1() •    'This is our DataSet created at Design Time       • MyDA.Fill(myDS, "Stores") •        'You have to use the same name as that of your Dataset that you created during design time • Dim oRpt As New CrystalReport1() •         ' This is the Crystal Report file created at Design Time • oRpt.SetDataSource(myDS) •         ' Set the SetDataSource property of the Report to the Dataset • CrystalReportViewer1.ReportSource = oRpt •         ' Set the Crystal Report Viewer's property to the oRpt Report object that we created • End Sub
