Hello.
I have a *.rpt-file, created in the "SAP Crystal Reports" program with a ttx-file as data source description.
For example, the .ttx file is very simple:
str1 String 25 test1
I need show this report by a WPF-application, and I want to use an "Object Collection" for filling its data.
I try chahge a data source for the report like this:
namespace WPFTest
{ public class Filds3 { public string str1 { get; set; } } public partial class MainWindow : Window { public CrystalReportsViewer crystalReportsViewer1; public MainWindow() { InitializeComponent(); try { this.crystalReportsViewer1 = new CrystalReportsViewer() { Height = 500, Width = 800 }; ReportDocument doc = new ReportDocument(); doc.Load("Report4.rpt"); var testValues2 = new ArrayList() { new Filds3 { str1 = "sd133" }, new Filds3 { str1 = "sd222" }, new Filds3 { str1 = "sd344" }, new Filds3 { str1 = "sd4323" }, }; string modelClassName = "WPFTest.Filds3"; NameValuePairs2 connectionProperties = new NameValuePairs2 { new NameValuePair2 { Name = DbConnectionAttributes.CONNINFO_DATABASE_DLL, Value = DbConnectionAttributes.DATABASE_DLL_CRDB_ADOPLUS }, new NameValuePair2 { Name = DbConnectionAttributes.QE_DATABASE_NAME, Value = "" }, new NameValuePair2 { Name = "QE_DatabaseType", Value = "ADO.NET (XML)" }, new NameValuePair2 { Name = DbConnectionAttributes.QE_SERVER_DESCRIPTION, Value = modelClassName }, new NameValuePair2 { Name = "QE_SQLDB", Value = false }, new NameValuePair2 { Name = "SSO ENABLED", Value = false }, }; NameValuePairs2 logonProperties = new NameValuePairs2 { new NameValuePair2 { Name = "ClassName", Value = modelClassName }, new NameValuePair2 { Name = "Internal Connection ID", Value = Guid.NewGuid().ToString() } }; foreach (CrystalDecisions.Shared.IConnectionInfo connection in doc.DataSourceConnections) { connection.SetLogonProperties(logonProperties); } foreach (CrystalDecisions.CrystalReports.Engine.Table table in doc.Database.Tables) { //TableLogOnInfo info = table.LogOnInfo; TableLogOnInfo newInfo = new TableLogOnInfo(); newInfo.TableName = modelClassName; DbConnectionAttributes newAttributes = new DbConnectionAttributes(); newAttributes.Collection = connectionProperties; newInfo.ConnectionInfo.Attributes = newAttributes; newInfo.ConnectionInfo.LogonProperties = logonProperties; newInfo.ConnectionInfo.ServerName = modelClassName; newInfo.ConnectionInfo.Type = ConnectionInfoType.CRQE; newInfo.ConnectionInfo.UType = 5; table.ApplyLogOnInfo(newInfo); string location = table.Location; table.SetDataSource(testValues2); // table.Location = "WPFTest_Filds3"; // Exception here } this.crystalReportsViewer1.ViewerCore.ReportSource = doc; this.crystalReportsViewer1.Owner = this; this.Grid1.Children.Add(this.crystalReportsViewer1); } catch (Exception e) { MessageBox.Show(e.Message); } }
}
}But I getting an Exception like:
Failed to load database information.
Error in File Report4 10384_8240_{4CDE0A62-05A9-4CBA-8A41-B185B3A3946A}.rpt:
Failed to load database information.
Tell me please, how I can correct my code for success.
Thank you.
