Hi Guys
We have written a program that uses SAP Crystal Reports. The machine and database that we wrote the report against, the system works perfectly, but when we change the database, we are having a few issues where the system says "Error in File Report_###.rpt: Failed to load database information."
We then proceeded to debug this and picked up something strange.
Here is our code:
TableLogOnInfo tableLogOnInfo = GetSQLTableLogOnInfo(server, DataUtility.DatabaseName, integratedLogin, userID, password);
for (int i = 0; i < report.Database.Tables.Count; i++)
{
Table table = report.Database.Tables[i];
table.ApplyLogOnInfo(tableLogOnInfo);
}
private static TableLogOnInfo GetSQLTableLogOnInfo(string serverName, string databaseName, bool integratedLogin, string userID, string password)
{
CrystalDecisions.ReportAppServer.DataDefModel.PropertyBag connectionAttributes = new CrystalDecisions.ReportAppServer.DataDefModel.PropertyBag();
connectionAttributes.Add("Initial Catalog", databaseName);
connectionAttributes.Add("Data Source", serverName);
connectionAttributes.Add("Initial Catalog", databaseName);
connectionAttributes.Add("User ID", userID);
connectionAttributes.Add("Integrated Security", integratedLogin);
DbConnectionAttributes attributes = new DbConnectionAttributes();
attributes.Collection.Add(new NameValuePair2("QE_DatabaseName", databaseName));
attributes.Collection.Add(new NameValuePair2("QE_LogonProperties", connectionAttributes));
attributes.Collection.Add(new NameValuePair2("QE_ServerDescription", serverName));
attributes.Collection.Add(new NameValuePair2("SSO Enabled", integratedLogin));
ConnectionInfo connectionInfo = GetConnectionInfo(serverName, databaseName, integratedLogin, userID, password);
connectionInfo.Attributes = attributes;
connectionInfo.Type = ConnectionInfoType.SQL;
TableLogOnInfo tableLogOnInfo = new TableLogOnInfo();
tableLogOnInfo.ConnectionInfo = connectionInfo;
return tableLogOnInfo;
}
public static ConnectionInfo GetConnectionInfo(string serverName, string databasename, bool integratedLogin, string UserID, string passWord)
{
ConnectionInfo connectionInfo = new ConnectionInfo();
connectionInfo.AllowCustomConnection = true;
connectionInfo.ServerName = serverName;
connectionInfo.DatabaseName = databasename;
connectionInfo.IntegratedSecurity = integratedLogin;
if (!integratedLogin)
{
connectionInfo.UserID = UserID;
connectionInfo.Password = passWord;
}
return connectionInfo;
}
Now, when this code runs, it shows that the integrated login on "tableLogOnInfo" = true but when "ApplyLogOnInfo" to the table, the reportdocument shows the integrated login to false. We also tried to use a SQL user, but using the SA user, and again, the tableLogOnInfo shows a password for the SA user, but the ApplyLogOnInfo shows no password, so we can never change the database on the report.
Please help, as we don't know what more to try.
Thanks in advance

Request clarification before answering.
See if it works in my test app, you will need to modify the code so run in debug and look for the commented lines to the parameters:
