Introduction
When you use the CrystalReportViewer object model to log on to a secure SQL Server
database, you must use classes from the CrystalDecisions.Shared namespace.
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. |
