A VB.NET application uses Crystal Reports for Visual Studio .NET as the reporting development tool.
How do you pass database logon information to a Crystal Report at runtime in this VB.NET application?
Crystal Reports for Visual Studio
To pass logon information to a Crystal Report at runtime, use the following code sample:
Dim crtableLogoninfos As New TableLogOnInfos()
Dim crtableLogoninfo As New TableLogOnInfo()
Dim crConnectionInfo As New ConnectionInfo()
Dim CrTables As Tables
Dim CrTable As Table
'If you are using a Strongly Typed report (Imported in 'your project) named CrystalReport1.rpt use the 'following:
Dim crReportDocument As New CrystalReport1()
'If you are using a Non-Typed report, and loading a report outside of the project, use the following:
Dim crReportDocument As New ReportDocument()
'Set the ConnectionInfo properties for logging on to the Database If you are using ODBC, this should be the DSN name NOT the physical server name. If you are NOT using ODBC, this should be the physical server name
.ServerName = "DSN or Server Name"
'If you are connecting to Oracle there is no 'DatabaseName. Use an empty string.
.DatabaseName = ""
.DatabaseName = "DatabaseName"
.UserID = "Your User ID"
.Password = "Your Password"
'This code works for both user tables and stored procedures. Set the CrTables to the Tables collection of the report
CrTables = crReportDocument.Database.Tables
'Loop through each table in the report and apply the LogonInfo information
For Each CrTable in CrTables
CrTableLogonInfo = CrTable.LogonInfo
CrTableLogonInfo.ConnectionInfo = crConnectionInfo
'If your DatabaseName is changing at runtime, specify the table location.
'For example, when you are reporting off of a Northwind database on SQL server you should have the following line of code:
crTable.Location = "Northwind.dbo." & crTable.Location.Substring(crTable.Location.LastIndexOf(".") + 1)
'Set the viewer to the report object to be previewed.
CrystalReportViewer1.ReportSource = crReportDocument
private CrystalReport1 crReportDocument = new
private Database crDatabase;
private Tables crTables;
private Table crTable;
private TableLogOnInfo crTableLogOnInfo;
private ConnectionInfo crConnectionInfo = new ConnectionInfo ();
//Setup the connection information structure to log on to the data source for the report.
// If using ODBC, this should be the DSN. If using OLEDB, etc, this should be the physical server name
crConnectionInfo.ServerName = "DSN or Server Name";
// If you are connecting to Oracle there is no DatabaseName. Use an empty string i.e. crConnectionInfo.DatabaseName = "";
crConnectionInfo.DatabaseName = "DatabaseName";
crConnectionInfo.UserID = "Your UserID";
crConnectionInfo.Password = "Your Password";
// This code works for both user tables and stored procedures. Get the table information from the report
crDatabase = crReportDocument.Database;
crTables = crDatabase.Tables;
//Loop through all tables in the report and apply the connection information for each table.
for (int i = 0; i < crTables.Count; i++)
crTable = crTables [i];
crTableLogOnInfo = crTable.LogOnInfo;
crTableLogOnInfo.ConnectionInfo = crConnectionInfo;
//If your DatabaseName is changing at runtime, specify the table location. For example, when you are reporting off of a Northwind database on SQL server you should have the following line of code:
crTable.Location = "Northwind.dbo." + crTable.Location.Substring(crTable.Location.LastIndexOf(".") + 1)
//Set the viewer to the report object to be previewed.
crystalReportViewer1.ReportSource = crReportDocument;
" If you are using a web application make sure that you do not specify or call the DataBind in your code as this will nullify the code above.
" If the above code still results in a logon failure in a web application (ASP.NET), refer to knowledge base article c2010867 (For Windows 2000) or c2013758 (Windows 2003 Server (IIS6)), and ensure that the ASPNET account has sufficient access to the database, reports, and the application directories.
The additional knowledgebase articles referenced can be found at:
" If you are changing database at runtime, it is important that you specify the table location after you apply logon information (this is a case sensitive property). You can either specify the table name only or the fully qualified table name such as
crTable.location = "databaseName.dbo.tablename";
//Refer to knowledge base article c2010275 if you wish to change database logon information in the main and subreport.
" If you are reporting off an Access database, then specify either the 'ServerName' or 'DatabaseName' to the 'ConnectionInfo' Object depending on how you are connecting to Access.
For example, if you are connecting to Access through ODBC, then set the 'DatabaseName' for the 'ConnectionInfo' object as follows:
.DatabaseName = "C:\mydatabase\mydata.mdb"
If you are connecting to Access through OLE DB, then set set the 'ServerName':
.ServerName = "C:\mydatabase\mydata.mdb"
It is not possible to report of a secured Access database using a native connection. See knowledge base article C2010460 for more information.
" If you are using more than one database with different usernames and passwords, use a loop to pass in the different values.
