Created Issue: ValidationProvider and Validation of NumericUpDown Decimal Value

szymonk — Sun, 05 Jul 2009 13:15:27 GMT

As we now NumericUpDown.Value is Decimal type. If You will want boun it with object field which type is Int it will go on. Then if you will set attribute of ValidationApplication block RangeValidator[1,100] and then if You connect to this NumericUpDown ValidationProvider when Validation event occur You will get error of conversion. Validator will check what is type of field in our object it will get that is Int for that he will get convert class it will be Int32Converter. Then it will take the NumericUpDown.Value which is Decimal at this moment we will get Error that the value should be of specified Int type. I had modified my enterprise entlib src and repair it I check if value.GetType() is decimal then i convert it to string and it works. For me it's ok because for this NumericUpDown I hawe set it has no thousand separator.

New Post: Database.cs method GetSqlStringCommand is not marked virtual

leonard_h — Fri, 03 Jul 2009 20:45:58 GMT

Hi,

is there a reason why in class Database.cs the method "GetSqlStringCommand" is not marked virtual ?
In a proyect i'm working we're creating a spring proxy of the Database class, and while exposing the original interface, the method "GetSqlStringCommand" cant be proxied ,but all the other "execute*" methods do work and the only difference is that the other methods are virtual.

So is there a design decison for this? could it be changed in the future?

Thanks!

Database.cs

/// <summary>
/// <para>Creates a <see cref="DbCommand"/> for a SQL query.</para>
/// </summary>
/// <param name="query"><para>The text of the query.</para></param>
/// <returns><para>The <see cref="DbCommand"/> for the SQL query.</para></returns>
public virtual DbCommand GetSqlStringCommand(string query)
{
if (string.IsNullOrEmpty(query)) throw new ArgumentException(Resources.ExceptionNullOrEmptyString, "query");

return CreateCommandByCommandType(CommandType.Text, query);
}

New Post: The located assembly's manifest definition does not match the assembly reference.

Hi,

First thing to verify, make sure that the referenced assemblies are the custom ent lib dlls. Can you please remove the reference and add again? then have a rebuild. You've said that it worked for you, then what did you change before it started showing errors?

New Post: Wierd PIAB bug

peterjavornik — Fri, 03 Jul 2009 12:54:37 GMT

Hi we are using PIAB for security interception on our business objects. The current configuration uses a custom matching rule that matches all interface methods that derive for our base business logic interface and it worked perfectly until for some weird reason interception got called on Dispose method that is not a part of any of business interfaces that our rule matches. IDisposable is defined on our objects but the object needs to be cast to IDisposable before you can call dispose.

I checked the handler’s pipeline and it contained 6 instead of 5 (no. of methods in the interface) handler pipelines and the metadata key used to match for one was the same as the dispose method one. So interception is working as it should the weird thing is that the handler pipeline with dispose methods metadata key shouldn’t even be there and that this extra handler is not deterministic - it always at the same spot on a particular computer, but no 2 computers have the problem with the same business object and one computer even has handlers attached to GetType method that is not a part of any interface.

We also checked if all interfaces in our classes get handled but that’s not the case since most of our business classes implement at least 5-6 interfaces and only methods from our interface that derives from the for mentioned base interface get handled plus one extra method that causes problems.

Anyone else had this problem?

Hi,

The dll'd refered are Customized entLib dll's.So i have given public has null in web.config.The same settings worked for me but now i am getting this error when i have taken only Data(DAAB),ExceptionHandling(EHAB),Logging(project of Exception Handling Block), Logging.Database of Logging Application block projects and added them to my solution.Even this worked initiallly but suddenly not working.What is the reason.Please let me know.Thanks,

New Post: Asynchronous Application Block

AvanadeSupport — Fri, 03 Jul 2009 03:16:17 GMT

I've read somewhere that there was no strong demand for both Asynchronous and Aggregation Application block that's why they decided to leave them out.

Yup, that was GetSection, not GetSource, my fault. Not sure why that change didn't worked for you though. Anyway, here's a thread relating to your second question - http://entlib.codeplex.com/Thread/View.aspx?ThreadId=16623

The class CrytographicOperationErrorEventArgs is missing a 'p' in its name.

New Post: Programatically enabling/disabling category filters

jesterbratt — Thu, 02 Jul 2009 17:51:06 GMT

Actually I think the syntax is this:

LoggingSettings loggingSettings = (LoggingSettings)configuration.Sections.Get(LoggingSettings.SectionName);

So all seams to be working, but can you tell me how to force the application reconsult the configuration file settings immediatly after I call

entlibConfig.Save();

Thanks

Jess

jesterbratt — Thu, 02 Jul 2009 17:03:25 GMT

Thanks, but I get a compile error on this line: LoggingSettings loggingSettings = (LoggingSettings)entlibconfig.GetSource("loggingConfiguration");

Error: "System.configuration.configuration does not contain a definition for 'GetSource' and no extension method 'GetSource' accepting a first argument of type Syste.Configuratin.Configuration coudl be found"

Does this compile for you?

I tried changing to GetSection but that gives an error as well:

Error Cannot convert type 'System.Configuration.ConfigurationSection to 'Microsoft.Practices.EnterpriseLIbrary.Logging.Configuration.LoggingSettings

New Comment on "How do I implement a conditional validation?"

How do I implement conditional validation that used by the PropertyProxyValidator? SelfValidation does not work with the PropertyProxyValidator.

New Post: Enterprise Library and .NET 4.0 beta 1 - it doesn't work

mdkowalski — Thu, 02 Jul 2009 14:31:08 GMT

Would you anticipate that this issue would be corrected by the time that beta2 is released?

Also, when I attempted to use some Entlib assemblies within a .NET 4.0 beta 1 project, I was presented with some errors during compilation related to indirect references to .NET 2.0 assemblies such as System.Management. Is this issue related to the one you mention above?

Commented Issue: Logging of Exceptions fails after a while

BMukund — Thu, 02 Jul 2009 14:06:16 GMT

We are using enterprise library 3.1 (Logging and Exception handling application blocks) in our ASP.NET Web application. Our application has the code and the required configuration to log the error messages to both flat file and event log when there is an exception. Logging is working fine, but intemittently it stops logging any messages even when there is an exception. Logging starts working normally as soon as we restart the IIS, but after a while it stops again. We are not able to find the pattern or root cause of when the logging is stopped. Has anyone faced similar issue? Anyone has any ideas or suggestions to debug or fix the issue?

Software / Server Environment:
Enterprise Library 3.1 (May 2007), .NET 2.0, ASP.NET 2.0, IIS 6.0, Windows 2003 Server
Comments: ** Comment from web user: BMukund **

We have the same issue. On one of our environments when you deploy application and restart IIS the logging works however it stops at some point and then never logs any error messages. Again if we restart IIS the logging starts again but can stop at any time,.

Any pointer in right direct will be really appreciated.

Thanks for your reply.

I am trying to encapsulate everything related to logging in the class library with custom trace listener, custom logger, custom logentry and related config file and I want Web App to just call custom logger class and its method.

New Post: Asynchronous Application Block

ronnared — Thu, 02 Jul 2009 10:36:20 GMT

Thank, I already found that but not already test yet. Another way is the code project http://www.codeproject.com/KB/cs/AsynchronousCodeBlocks.aspx.

Both are Net 2.0 and for the first one, it including in EntLib2.0, so I concern about version compatible becauese our team use Enterprise Lib 4.1

And I am just a stupid beginner in C# so want to look for the uptodate Code Block without any modified.

Asynchronous is very complicated topic, I think it should have a place in next version

AvanadeSupport — Thu, 02 Jul 2009 05:41:21 GMT

It was already deprecated way back, not sure exactly what version. You can download it now separately - http://msdn.microsoft.com/en-us/library/ms998466.aspx.
