Architecture :: How To Log Dal Exception And Showing Alert To User / Exception Occurs
Aug 3, 2010I am working on a 3-tier asp.net application. Currently I'm stuck up in a situation where I need to handle a specific type of exception (User Defined) in DAL and Show alert to the user if that exception occurs in DAL.
I tried following things:
1) I raised that exception from the DAL and catch it in BLL and throw a new BLL exception to for that DAL exception and finally catch it in the UI layer to show the alert to the user. I've successfully implement this in my project. But there are some issues in this approach. First of all I feel this is not right way to do this as it may lead to performance related issues. Secondly, the application contains more than 500 pages and classes. so I need to attach additional catch block in every method to catch the BLL exception. which is the last option i'd like to take.
2) in second approach I logged the the DAL exception into a text file. but problem in this approach is that how could the UI layer know that exception has occurred and show the alert to the user. Is there any event in asp.net where i could handle all this activities?
my question is what is the best approach to handle this type of situation? Will Exception handling block help me in this?
I've tried reading many articles on this but i couldn't get an answer for my question? I might not be using right keywords for my search.

Jul 2, 2010i have this application structure:
1. Presentation Layer which calls
2. Business Logic Layer which in turn calls
3. Data Access Layer to do the dealing with the database.
Now i have a Contacts page from where i can add a new contact to the database.So to add a New Contact i fill in all the required details and then call a Add Method (residing in the BLL) from the page, which in turn call a Add Method residing in the DAL.this method in the DAL returns the Current Identity of the record which is then return back to the BLL method and finally delivered on the page.this is fine. but what if a get an exception how do i handle it properly because the method in DAL has a return type of int and i dont want to throw another error!! coz other wise i will have to write try catch in almost all the methods.
//something like this
public int AddMethod(ContactClass contactObj)
{
int result = 0;[code]...
rather i want to show the user a user-friendly message which they can easily understand and in the mean while i will send a mail to myself documenting the Error that just occurred.how can i implement my custom exception classes.
Ways To Identify A Particular Exception From Exception Class?

WCF / ASMX :: Accessing A Published Web Service Gives Null Ref Exception?
Sep 2, 2010I have an Asp.net web service that I created using Visual Studio 2005. I can acess the web service in my test environment, call methods and return data as expected. If this web service is published to the outside world (Outside of the company firewall), it will return a null why this might be happening? The same code is being used,against the same database. The only difference is that the published website is giving back the null reference exception. If I type in the URL for the web service "https://secure.theSiteGeist.com/wsIndigo.asmx" a list of methods for the web service is displayed in my browser. Yet if I try and call any methods on the web service I get back the null reference exception. Note that the URL I posted above is not the real name of my web service, but is just used for reference sake.

View 1 RepliesConsole Application Calling Datalayer Throws An Exception "The Type Initializer For Threw An Exception."
Aug 17, 2010I have simple 3 tier web application and have mostly CRUDE functionalities. Recently I required to add new console application to the existing solution in which I call data layer methods for retrieving data from DB but I get an exception "The type initializer for threw an exception."When I debugged I found that the exception is thrown at datalayer on first line of class where I get connectionstring from
web.config, the code is public static readonly string CONNECT_STRING =
ConfigurationManager.ConnectionStrings["DbConnectString"].ConnectionString;
Now if I hardcode the connection string value like public static readonly string CONNECT_STRING = "Data Source=XYZ;uid=sa;password=XXX;initial catalog=ABC;"
it works fine.I don't understand what is the issue here as web application works fine with this datalayer.

View 1 RepliesWCF / ASMX :: Security Fault / Getting A FaultedState Error
Jun 10, 2010I have a Client Application calling a WCF service. I was getting a faultedState error on the client, after looking around I discovered this was because the client proxy was in a using statement and was actually hiding a security error. I have not been able to fix this fault and have not been able to find much online about it. I have undone the changes that caused this error to happen and the error continued, I have even went back to a different version of the solution and still encountered this error. I later set up my solution on another machine and pretty much encountered the same problem after working for a couple of hours.
I have the service and client running in my local solution. I'm using visual studio 2008. The error I get is "An unsecured or incorrectly secured fault was received from the other party. See the inner FaultException for the fault code and detail." and inner exception is "An error occurred when verifying security for the message."

WCF / ASMX :: "decryption Operation Failed" Exception When Calling Web Service
Dec 20, 2010These types of exceptions always irritate me because they are almost impossible to reproduce consistently and have almost no documentation other than the cryptic error itself to have any idea on how to fix the problem. So I have a Windows Service that makes a call to a .asmx web service over https on a polled interval every 20 minutes. Once in a great while the following exception message is returned:
Message: The underlying connection was closed: An unexpected error occurred on a receive.
Inner Message: System.IO.IOException: The decryption operation failed, see inner exception. ---> System.ComponentModel.Win32Exception:
The specified data could not be decrypted --- End of inner exception stack trace --- at
System.Net.Security._SslStream.ProcessReadErrorCode(SecurityStatus
errorCode, Byte[] buffer, Int32 offset, Int32 count, AsyncProtocolRequest asyncRequest, Byte[] extraBuffer) at System.Net.Security._SslStream.ProcessFrameBody(Int32 readBytes, Byte[] buffer, Int32 offset, Int32 count, AsyncProtocolRequest asyncRequest) at
System.Net.Security._SslStream.StartFrameBody(Int32 readBytes, Byte[] buffer, Int32 offset, Int32 count, AsyncProtocolRequest asyncRequest) at System.Net.Security._SslStream.StartFrameHeader(Byte[] buffer, Int32 offset, Int32 count, AsyncProtocolRequest asyncRequest)

buffer, Int32 offset, Int32 size) at System.Net.PooledStream.Read(Byte[] buffer, Int32 offset, Int32 size) at System.Net.Connection.SyncRead(HttpWebRequest request, Boolean userRetrievedStream, Boolean probeRead)
So from reading the above message there was an error on receive and the data could not be decrypted. The does not occur consistently, so I don't have a good way of reproducing it. I also lack at low level messaging knowledge and I feel that this is the answer behind this exception; i.e. dropped packets and an incomplete message not appearing to be the same message as sent from the service or something. Any .asmx gurus out there that can give insight and possibly prevention suggestions for the above issue?

i had scenario where i had to fill list of object class without knowing its type see code:
Added contract

{
try

}
method at DAL(ReferenceTableDAL):
public static dynamic GetReferenceTableData(string tableName)
{
Database db = DatabaseFactory.CreateDatabase(Flags.ConnectionStringKey);
DbCommand dbCommand = db.GetStoredProcCommand("USP_GETTABLEDATA");
dynamic objDynamic = null;
if (tableName.ToLower() == "a")
{
objDynamic = new List<A>();
}
else if (tableName.ToLower() == "b")
{
objDynamic = new List<B>();
}
else if (tableName.ToLower() == "c")

}
try

objDynamic.Add((C)dataRow);
}
}
}
catch (Exception ex)
{
throw;
}
return objDynamic;
}
@ Aspx
try
{
using (DataServiceRef.DataServiceClient petService = new DataServiceRef.DataServiceClient())
{
dynamic tableData = petService.GetReferenceTableData(tableName);
//tableData is null ,exception
}
}
catch (Exception ex)
{
throw;
}
There is no exception at dal or service end when i debug list gets filled ok but when returns to aspx error at aspx(no exception gets caught at @ service) but exception at aspx i.e:
Message:The underlying connection was closed: The connection was closed unexpectedly.
