I need to be able to set a Data Source for both Access and xBase types in an RPT file I've loaded in a .NET Application.
I've tried this.
CrystalDecisions.CrystalReports.Engine.ReportDocument reportDocument1 = new CrystalDecisions.CrystalReports.Engine.ReportDocument();
reportDocument1.Load(@"C:\MyCrystal.rpt", CrystalDecisions.Shared开发者_如何学Python.OpenReportMethod.OpenReportByTempCopy);
string Constr = "MyConnectionString";
// initialize an object to pull out the needed pieces for the login information.
SqlConnectionStringBuilder sb = new SqlConnectionStringBuilder(ConStr);
// Turn off integrated Security
foreach (IConnectionInfo i in reportDocument1.DataSourceConnections)
{
i.IntegratedSecurity = false;
}
// Set the LogonInfo for each Data Source
foreach (CrystalDecisions.CrystalReports.Engine.Table CrTable in reportDocument1.Database.Tables)
{
TableLogOnInfo logOnInfo = CrTable.LogOnInfo;
String dbtype = logOnInfo.ConnectionInfo.Attributes.Collection.LookupNameValuePair("QE_DatabaseType").Value.ToString().Trim();
if (dbtype.Equals("xBase"))
{
NameValuePairs2 lp = logOnInfo.ConnectionInfo.LogonProperties;
foreach (NameValuePair2 nvp in lp)
{
if (nvp.Name.ToString().Trim().Equals("Data File"))
nvp.Value = @"C:\MyDbaseFile.dbf";
}
CrTable.ApplyLogOnInfo(logOnInfo);
}
else if (dbtype.Equals("OLE DB (ADO)"))
{
bool sql = true;
NameValuePairs2 lp = logOnInfo.ConnectionInfo.LogonProperties;
NameValuePair2 prov = lp.LookupNameValuePair("Provider");
if (!prov.Value.ToString().ToUpper().Equals("SQLOLEDB"))
{
sql = false;
NameValuePair2 ds = lp.LookupNameValuePair("Data Source");
ds.Value = @"C:\MyAccess.mdb";
}
if (sql)
{
// Set the connection information for the table in the report.
logOnInfo.ConnectionInfo.UserID = sb.UserID;
logOnInfo.ConnectionInfo.Password = sb.Password;
logOnInfo.ConnectionInfo.ServerName = sb.DataSource;
logOnInfo.ConnectionInfo.DatabaseName = sb.InitialCatalog;
}
CrTable.ApplyLogOnInfo(logOnInfo);
}
}
reportDocument1.VerifyDatabase();
reportDocument1.ExportToDisk(CrystalDecisions.Shared.ExportFormatType.PortableDocFormat, @"C:\MyTest.pdf");
I get a LogOnException on the VerifyDatabase() (or if it's not there the ExportToDisk) I've dumped out the values before and after and I see the change... but I must be doing something wrong. Please help!
Got some code from an SAP support person for this.
