For handling application errors which throw outside the controller logic (global.asax, routes, filters etc) you should provide static html error page, otherwise asp.net default error page will be displayed.

Been looking for this for a long time for our build server without finding any good solution. Thank you very much!

This is really helpful,thank you so much. Only thing that I did was change Response.StatusCode = (int)HttpStatusCode.NotFound; took it from view and added it to error controller berfore returning views.

Why not do the following instead:

Using context = New NewProData_RC3Entities

Dim Ids As New List(Of Integer)
Ids.Add(1)
Ids.Add(2)
Dim query = context.Addresses.Where(Function(x) Ids.Contains(x.Address_PK))
Dim result1 = query.ToList()
End Using

I think the blog post needs a revisit as many things have changed now.

I would suggest you to have a look at
JSF 2 (You get the master page and more from this)
Primfaces 3 (http://primefaces.org)
Pretty Faces (http://ocpsoft.com/prettyfaces/)

This fixes most of all what you need. Most of the other things are already explained by Others in previous comments.

We have both .Net team and Java Team, while the JSF team with primefaces delivers faster than the .net team in most scenarios. The widgets in primefaces are amazing, the xhtml file is clean and makes developers comfortable in implementing AJAX too, no javascript code is required except any 3rd party usage comes to the game.

Hi, I am writing a serial transaction and had some troubles.
If I only execute one thread, it executes fast, no waiting.
If I execute two or more threads, the first thread that complete takes too much time but subsequent threads are fast, why?

If I run two process concurrently of this program, each process's first thread takes too much time to complete but subsequent are fast, is this normal?

I am using sql express 2008

tanks.

class Program
{
int numero;

Program(int numero)
{
this.numero = numero;
}

static void Main(string[] args)
{
Console.WriteLine("Puede presionar una tecla para salir en cualquier momento");

for (int i = 0; i < 10; i++)
{
Program p = new Program(i + 1);
Thread t = new Thread(p.Ejecutar);
t.Start();
}

Console.ReadKey();
}

public void Ejecutar()
{
bool esPosibleProseguir = true;
while (esPosibleProseguir)
{
Database1Entities cx = new Database1Entities();
TransactionOptions opts = new TransactionOptions();
opts.IsolationLevel = System.Transactions.IsolationLevel.Serializable;
System.Transactions.TransactionScope scope = new System.Transactions.TransactionScope(TransactionScopeOption.Required, opts);

try
{
//var mayor = cx.Numeracion.First();
//int nuevo = mayor.Numero + 1;
cx.Connection.Open();

int nuevo = cx.VistaNumero.First().Actual;

var per = new Persona();
per.Nombre = string.Format("Persona-{0}", nuevo);
per.Ci = (1000 + nuevo).ToString();
per.Numero = nuevo;
cx.Persona.AddObject(per);

//mayor.Numero = nuevo;

cx.SaveChanges();
scope.Complete();

Console.WriteLine("Hilo: {0}, Crea persona: {1}", this.numero, nuevo);
break;
}
catch (UpdateException ex1)
{
esPosibleProseguir = true;
}
catch (TransactionAbortedException ex2)
{
esPosibleProseguir = true;
}
catch (Exception ex)
{
Console.WriteLine("Hilo: {0}, Excepción: {1}, Mensaje: {2}", this.numero, ex.GetType().Name, ex.Message);
esPosibleProseguir = false;
}
finally
{
DisponerObjeto(scope);
DisponerObjeto(cx);
}
}
}

private void DisponerObjeto(IDisposable obj)
{
try
{
obj.Dispose();
}
catch (Exception ex)

Console.WriteLine("Hilo: {0}, Excepción: {1}, Mensaje: {2}", this.numero, ex.GetType().Name, ex.Message);

Hi,

I encountered the following error when used the above publish to filesystem method

MSB3021 unable to copy because a file or directory with the same name already exists.

Any ideas?

Hi, interesting to read your comparison. There are a few things not entirely correct, let me explain:

>All of this goes into the one XML file.

This is not true and never had been true. From the beginning one could use the javax.faces.CONFIG_FILES parameter to specify multiple different files. You could have one xml for your managed beans, one for your navigation rules etc.

In JSF 2.x the faces-config.xml files are largely redundant. In JSF 2.1 (current version) there isn't any kind of XML configuration file required if you are satisfied with the defaults (not even web.xml). See e.g. http://jdevelopment.nl/minimal-3tier-java-ee-app-xml-config/

Validators, managed beans, and a lot more are now recommended to be declared using a simple annotation (metadata) on the class in question. Navigation can make use of implicit rules, which means you don't define any rule but use the page (view) name directly.

>JSF is a POST->Redirect, GET->Response.

Well, there always has been the h:outputLink, and you could of course use the plain html a href. The downside of these were that you had to specify the full URL. In JSF 2.0 there's the h:link and h:button that support GET based navigation. There's also first-class support available to process GET based requests.

>No Page Templating Support

Also not entirely true. Facelets solves this and has been doing it for quite some time. Three years prior to writing your article, this one appeared: http://www.ibm.com/developerworks/java/library/j-facelets/

It was a separate download back then, but there was very little reason not to use it. Nowadays in JSF 2.0 JSP has been completely deprecated and Facelets is the default templating language.

>In JSF, it is awkward and difficult to communicate data between pages.

For communication between requests to the same page, there is now the view scope. For communication between different pages there are various tools, like The Flash (inspired by RoR, like TempData), GET requests and because JSF can easily piggyback on CDI (new in Java EE 6), the conversation scope. Various extension projects (Seam 3, Apache CODI) allow you to very easily add additional scopes for communication between pages.

>JSF doesn't really support URL query string parameters (since every link is a POST)

As explained above, you could always use plain links or output links. The GET support in JSF 2.0 has first class support for query parameters and the redirect mechanism also allows one to use query parameters.

Please see the updated version of the page you linked wrt communication between beans: http://balusc.blogspot.com/2011/09/communication-in-jsf-20.html

>JSF doesn't come with any of this stuff [AJAX/JS]ready and out of the box and due to its awkward page navigation system, makes it difficult to incorporate one of the existing technologies into it.

Again not entirely true. Among others the a4j (ajax4jsf) library demonstrated very early on how AJAX could be used with JSF. This was actually quite easy. You just put the a4j:ajax tag around any existing non-ajax-aware component and it was ajaxified. This approach has been incorporated into the JSF standard in 2.0.

You could also always use javascript on your JSF views. There was no specific restriction that prevented this.

Hope this helped to clear up things a little ;)

This example is fantastic. Congratulations!!!

I have a doubt. In this example, you put only Equal condition.

In my scenario, I'd like put the LIKE Command. For example, tag.Name Like "abc".

Again, congratulations!!!

Note that this won't work if you have any mixed mode assemblies.

Stefan commented on "Removing a Windows System Certificate Store"

Stefan — Tue, 30 Aug 2011 06:29:17 GMT

I'm sorry to say, but I'm definitely tired :-(

I had to run my little utility at an elevated administrative level in order to delete certificate stores from local machine.

Arghhh... I should have been aware of this (not the first time it happens).

Thanks for this wonderful blog and useful information.

Stefan commented on "Removing a Windows System Certificate Store"

Stefan — Tue, 30 Aug 2011 06:09:46 GMT

Thank you for pointing some of us in the right direction.

I have a question: Have you ever tried to remove/delete a certificate store from the local machine instead of current user?

I managed to delete certificate stores from the current user but never from the local machine. Curiously enough, the CertUnregisterSystemStore() call with (CERT_STORE_DELETE_FLAG | CERT_SYSTEM_STORE_LOCAL_MACHINE) ends up successfully every single time but without any effect!

Michel I. Gallant (http://www.jensign.com/JavaScience/www/deletesystemstore/index.html) has a Java implementation where he seems to suggest that "Only deletion of CERT_SYSTEM_STORE_CURRENT_USER stores is enabled". I wonder if he refers to Windows or to his own program. MSDN does not state anything clearly in this matter.

Any comments are welcome.

I have been using this successfully on 32 bit Win 7 and Win XP Pro. On 64 bit Win 7, this fails for release builds. However, if you decorate you Program.Main with [MethodImpl(MethodImplOptions.NoOptimization)] it magically works. You can also create a static constructor for your Program class and add the AssemblyResolve event handler there without having to use MethodImpl attribute.

This is curious.

I created a test web app with VS2010 and this method worked perfectly. However, I tried it on our actual application and it fails with a bunch of errors.

To figure out what was wrong, I set up a new test scenario with my initial test web app by creating a new class library project and then referencing this project (not its DLL) by my web app (I also made sure to put some code in my web app that actually referenced code in the class library). When I tried your command line method, it failed with the same errors that I got when I tried this on our production app. I then removed the reference to the class library project and instead referenced its DLL directly. The build worked just fine after that.

How is one supposed to deal with this situation?

Wow, that is really cool! Worked for me.

Tried ILMerge as well, did not work. This is really Cool. I will link to this! (So i can remember it for the next time ;))
All those paid solutions have nothing on this one.
