The properties of the ConnectionInfo class are used to connect to the database server or ODBC data sources. In this tutorial, you set the ServerName, DatabaseName, UserID and Password properties. If you choose only to set the DatabaseName, UserID, and Password properties, then you are logged on to the default server of the database that you have specified within the report. However, if you choose to assign an alternate ServerName property, you can redirect the report to a different server at runtime. You retrieve the TableLogOnInfos instance from the LogOnInfo property of the CrystalReportViewer control. Then, you assign the ConnectionInfo instance to each TableLogOnInfo object in the TableLogOnInfos instance. The logon code in this tutorial also works for subreports that are inserted into the main report. For the ReportDocument object model, you must modify the code to work for subreports. The ReportDocument object model is recommended over the CrystalReportViewer object model. Creating a Report Connected to a Secure SQL Server Database To begin, create a report that draws its information from the Northwind database. Note Northwind is a sample database provided with SQL Server. Some setup is required as a prerequisite to this tutorial. Prerequisite Database Setup 1. SQL Server configuration: If you have SQL Server (or the OEM version, MSDE) installed, it must be configured to require SQL Server Authentication. If you do not have SQL Server (or the OEM version, MSDE) installed, you must install MSDE with SQL Server Authentication set to "True." 2. The Northwind database provided with SQL Server must be installed and verified that it requires SQL Server Authentication. 3. A limited access account must be created for use within the Web site. To install MSDE with SQL Server Authentication, or the Northwind database, go to the following sections from Appendix: System Setup in this documentation: Appendix: MSDE Installation with Windows or SQL Server Authentication Appendix: Northwind Database Installation Appendix: Security: Creating a Limited Access Database Account Once you have configured SQL Server and the Northwind database according to the sections above, you are ready to create a report that draws its information securely from a Northwind database. Walkthroughs Copyright © 2004 Business Objects Page 9 To create a report with secure data from the Northwind database Note This procedure works only with a project that has been created from Appendix: Project Setup. Project Setup contains specific namespace references and code configuration that is required for this procedure, and you will be unable to complete the procedure without that configuration. Therefore, before you begin this procedure, you must first follow the steps in Appendix: Project Setup. 1. In Solution Explorer, right-click the project name that is in bold type, point to Add, and then click Add New Item. 2. In the Add New Item dialog box, in the Templates view, select the Crystal Report template. 3. In the Name field, enter the name "NorthwindCustomers.rpt", and then click Open. Note If you have not registered before, you may be asked to register. To find out how to register, see Appendix: Crystal Reports Registration and Keycode. 4. In the Create New Crystal Report Document panel of the Crystal Reports Gallery dialog box, select Using a Report Wizard. 5. In the Choose an Expert panel, select Standard. Click OK. The Standard Report Creation Wizard window appears. 6. In the Available Data Sources panel, expand the Create New Connection folder. 7. From the subfolder that opens, expand the OLE DB (ADO) folder. The OLE DB (ADO) window appears. 8. Select Microsoft OLE DB Provider for SQL Server, and then click Next. 9. Enter the values for your database server, user id and password into the Server, User ID and Password fields. 10. From the Database drop down list, select "Northwind." Leave the Integrated Security checkbox unchecked because you are using SQL Server authentication instead of NT authentication. 11. Click Finish. The OLE DB folder is now expanded, showing your database server, and within it, the Northwind database. 12. Expand the nodes Northwind, dbo, and Tables, and then select the Customers table. 13. Click the > symbol to move the table into the Selected Tables panel, and then click Next. 14. Expand the Customers table, and then hold down the Ctrl key while you click CompanyName, ContactName and City. 15. Click the > symbol to move these fields into the Fields to Display panel, then click Next. 16. In the Available Fields panel, under Report Fields, select Customer.City, then click the > symbol to move the field into the Group By panel, and then click Finish. The NorthwindCustomers report is created and loaded into the main window of Visual Studio. You are now ready to bind the report to the CrystalReportViewer control. Walkthroughs Copyright © 2004 Business Objects Page 10 Binding the Report Without Logon Code In Appendix: Project Setup, you have placed a CrystalReportViewer control on the Web or Windows Form. In the previous step, you have added a NorthwindCustomers report to the project. In this section, you bind the file directory path of the NorthwindCustomers report to the CrystalReportViewer control. Then you test whether the report displays correctly when the database logon code has not been set. To bind the file directory path of the NorthwindCustomers report to the CrystalReportViewer control 1. Open the Web or Windows Form. 2. From the View menu, click Code. 3. Locate the ConfigureCrystalReports() method (that you have created in Appendix: Project Setup). 4. Declare a string variable, name it reportPath, and assign to it a runtime path to the local report. This path is determined differently for Web Sites and Windows projects: For a Web Site, pass the name of the local report file as a string parameter into the Server.MapPath() method. This maps the local report to the hard drive file directory path at runtime. [Visual Basic] Dim reportPath As String = Server.MapPath("NorthwindCustomers.rpt") [end] [C#] string reportPath = Server.MapPath("NorthwindCustomers.rpt"); [end] For a Windows project, concatenate the Application.StartupPath property with a backslash and the local report file name. This maps the report to the same directory as the Windows executable file. Note At compile time you will copy the report to the directory containing the executable file. [Visual Basic] Dim reportPath As String = Application.StartupPath & "\" & "NorthwindCustomers.rpt" [end] [C#] string reportPath = Application.StartupPath + "\\" + "NorthwindCustomers.rpt"; [end] 5. Assign the file directory path of the NorthwindCustomers report to the ReportSource property of the CrystalReportViewer control. [Visual Basic] myCrystalReportViewer.ReportSource = reportPath [end] Walkthroughs Copyright © 2004 Business Objects Page 11 [C#] crystalReportViewer.ReportSource = reportPath; [end] You are now ready to build and run your project. It is expected that the report loading will fail, because code has not yet been written to log onto the database. To test the loading of the NorthwindCustomers report 1. From the Build menu, select Build Solution. 2. If you have any build errors, go ahead and fix them now. 3. If you use a non-embedded report in a Windows project, locate the compiled Windows executable in the \bin\debug\ subdirectory, and then copy the report to that subdirectory. Note To have the non-embedded report loaded by the Windows executable at runtime, the report must be stored in the same directory as the Windows executable. 4. From the Debug menu, click Start. Note If you are developing a Web Site in Visual Studio 2005, and this is the first time you have started debugging, a dialog box appears and states that the Web.config file must be modified. Click the OK button to enable debugging. The NorthwindCustomers report will not display. It will display after you add the database logon code. Note Results may vary, depending on the version of Crystal Reports that you use. For example, if you have Crystal Reports 10 and up installed, you are prompted for database logon information for that report. This is a new feature of Crystal Reports Developer and Crystal Reports for Visual Studio 2005. If you are running a previous version of Crystal Reports, an exception is thrown. In either case, you must follow the next step procedure to create a fully functional application. 5. Return to Visual Studio and click Stop to exit from debug mode. Adding the Report Logon Code You are now ready to add the logon code to the code-behind class. You begin by creating a private helper method, SetDBLogonForReport() . To create and code the SetDBLogonForReport() method 1. Return to the code-behind class for this Web or Windows Form. 2. At the bottom of the class, create a new private method named SetDBLogonForReport() with ConnectionInfo passed into the method signature. [Visual Basic] Private Sub SetDBLogonForReport(ByVal myConnectionInfo As ConnectionInfo) End Sub [end] [C#] private void SetDBLogonForReport(ConnectionInfo connectionInfo) Walkthroughs Copyright © 2004 Business Objects Page 12 { } [end] 3. Within this method, retrieve the TableLogOnInfos instance from the LogOnInfo property of the CrystalReportViewer class. Note To make the TableLogOnInfos class accessible, include an "Imports" [Visual Basic] or "using" [C#] statement at the top of the code-behind class for the CrystalDecisions.Shared namespace. (You added this declaration in Appendix: Project Setup.) TableLogOnInfos is an indexed class that contains instances of the TableLogOnInfo class. [Visual Basic] Dim myTableLogOnInfos As TableLogOnInfos = myCrystalReportViewer.LogOnInfo [end] [C#] TableLogOnInfos tableLogOnInfos = crystalReportViewer.LogOnInfo; [end] 4. Create a foreach loop that loops through each TableLogOnInfo instance in the TableLogOnInfos indexed class instance. [Visual Basic] For Each myTableLogOnInfo As TableLogOnInfo In myTableLogOnInfos Next [end] [C#] foreach(TableLogOnInfo tableLogOnInfo in tableLogOnInfos) { } [end] 5. Within the foreach loop, set the ConnectionInfo property of TableLogOnInfo to the ConnectionInfo parameter. [Visual Basic] myTableLogOnInfo.ConnectionInfo = myConnectionInfo [end] [C#] tableLogOnInfo.ConnectionInfo = connectionInfo; [end] This step procedure has created a method to set the logon for the database. However, you must modify the ConfigureCrystalReports() method to address this method, for the report to be aware that it has database logon information.
