DataTransfer Error

Question

I have written following lines of code, but when TransferData() method is called, it generates error "Property LoginSecure cannot be changed or read after a connection string has been set."
 Can anybody help me? Thanks in advance....
Code:
//1. Create Transfer Object
Transfer transObj = new Transfer();
//transObj=new Transfer(server.Databases[fromdatabasename]);
transObj.DestinationLoginSecure = false;
transObj.DestinationLogin = "sa";
transObj.DestinationPassword = "test";
//Set Destination Server
//Build a "serverConnection" with the information of the "sqlConnection"
destSrvCon =
new ServerConnection(sqlCon);
//The serverConnection is used in the ctor of the Server.
destServer = new Server(destSrvCon);
transObj.DestinationServer = destServer.Name.ToString();
//2. Define Transfer Object's Properties
transObj.Database = server.Databases["Aworks"];
transObj.DestinationDatabase = "AWorksCopy";
transObj.Options.WithDependencies =true;
transObj.Options.ContinueScriptingOnError = true;
transObj.CopySchema = true;
transObj.CopyData = true;
transObj.CopyAllTables = true;
//4. Finally Transfer Data
transObj.TransferData();
//transObj.ScriptTransfer();

Hi  ,
For Dan : thanks for the link you provided , but , maybe , you have done a little error with it as I am arriving on the page with the title "Preparing the Snapshot Folder".
For Ritesh , please , could you provide the full list of the exceptions which occurred for this error ?
One possibility could to display the stacktrace which is giving something something like that ( it is an example coming from another thread of this forum , which I am following ) ?
Message: An error occurred while transferring data. See the inner exception for details.
StackTrace:    at Microsoft.SqlServer.Management.Smo.Transfer.TransferData()
   at Microsoft.SqlServer.Dts.Tasks.TransferObjectsTask.TransferObjectsTask.TransferDatabasesUsingSMOTransfer()
InnerException-->Timeout expired.  The timeout period elapsed prior to completion of the operation or the server is not responding.
CREATE DATABASE failed. Some file names listed could not be created. Check related errors.

   at Microsoft.SqlServer.Management.Smo.Transfer.TransferData()
InnerException-->The wait operation timed out
It is always a good way to use a try / catch to catch at least the SqlException, SmoException and Exception  errors.
About your error message , I found this old thread :
http://social.msdn.microsoft.com/Forums/sqlserver/en-US/639011d5-c413-4d3c-acdf-d3480ad751b9/datatransfer-error?forum=sqlsmoanddmo
Maybe it could help you to solve your problem.
Don't forget that when you are using the Server class , all the methods of this class are relying on the SqlClient namespace including the classes SqlConnection , SqlException or SqlCommand ( it is why to trap the SqlException errors is always useful )
