The `ScriptIgnoreAttribute` class is in the **System.Web.Extensions.dll** assembly (Located under Assemblies &gt; Framework in the VS Reference Manager). You have to add a reference to that assembly in your class library project.

You can find this information at top of the MSDN page for the [ScriptIgnoreAttribute class][1].

I&#39;m using Ubuntu 9.04 x64 and when I write:

    gnome-terminal --tab

At the terminal, I expect it to open a new tab in the same terminal window. But it opens a new window instead.

I found out that its intention is to open a new tab in a new window, i.e., if I write:

    gnome-terminal --tab --tab

It will open a new window with two tabs.

So, the question is, how can I open a new tab in the _current_ window using a command in `gnome-terminal`?

I have the following code:

    $DatabaseSettings = @();
    $NewDatabaseSetting = &quot;&quot; | select DatabaseName, DataFile, LogFile, LiveBackupPath;
    $NewDatabaseSetting.DatabaseName = &quot;LiveEmployees_PD&quot;;
    $NewDatabaseSetting.DataFile = &quot;LiveEmployees_PD_Data&quot;;
    $NewDatabaseSetting.LogFile = &quot;LiveEmployees_PD_Log&quot;;
    $NewDatabaseSetting.LiveBackupPath = &#39;\\LiveServer\LiveEmployeesBackups&#39;;
    $DatabaseSettings += $NewDatabaseSetting;

When I try to use one of the properties in a string execute command:

    &amp; &quot;$SQlBackupExePath\SQLBackupC.exe&quot; -I $InstanceName -SQL `
      &quot;RESTORE DATABASE $DatabaseSettings[0].DatabaseName FROM DISK = &#39;$tempPath\$LatestFullBackupFile&#39; WITH NORECOVERY, REPLACE, MOVE &#39;$DataFileName&#39; TO &#39;$DataFilegroupFolder\$DataFileName.mdf&#39;, MOVE &#39;$LogFileName&#39; TO &#39;$LogFilegroupFolder\$LogFileName.ldf&#39;&quot;

It tries to just use the value of `$DatabaseSettings` rather than the value of `$DatabaseSettings[0].DatabaseName`, which is not valid.  
My workaround is to have it copied into a new variable.

I am looking for a method to disable the browser cache for an **entire ASP.NET MVC Website**

I found the following method:

    Response.Cache.SetCacheability(System.Web.HttpCacheability.NoCache);
    Response.Cache.SetNoStore();

And also a meta tag method (it won&#39;t work for me, since some MVC actions send partial HTML/JSON through Ajax, without a head, meta tag).

    &lt;meta http-equiv=&quot;PRAGMA&quot; content=&quot;NO-CACHE&quot;&gt;

But I am looking for a simple method to disable the browser cache for an entire website.

If the controller action has the OutputCache attribute specified on an action, is there any way to clear the output cache without having to restart IIS?

    [OutputCache (Duration=3600,VaryByParam=&quot;param1;param2&quot;)]
    public string AjaxHtmlOutputMethod(string param1, string param2)
    {
      var someModel = SomeModel.Find( param1, param2 );

      //set up ViewData
      ...

      return RenderToString( &quot;ViewName&quot;, someModel );
    }

I&#39;m looking at using `HttpResponse.RemoveOutputCacheItem(string path)` to clear it, but I&#39;m having trouble figuring out what the path should be to map it to the action method. I&#39;m going to try again with the aspx page that is rendered by ViewName.

Possibly I&#39;ll just manually insert the output of `RenderToString` into the `HttpContext.Cache` instead if I can&#39;t figure this one out. 

&lt;b&gt;Update&lt;/b&gt;

Please note that the OutputCache is VaryByParam, and testing out a hardcoded path &quot;/controller/action&quot; does not actually clear the outputcache, so it looks like it has to match &quot;/controller/action/param1/param2&quot;.

That means I&#39;ll probably have to revert to object level caching and manually cache the output for `RenderToString()` :(

I have a strongly-typed Partial View that takes a ProductImage and when it is rendered I would also like to provide it with some additional ViewData which I create dynamically in the containing page. How can I pass both my strongly typed object and my custom ViewData to the partial view with the RenderPartial call?

    var index = 0;
    foreach (var image in Model.Images.OrderBy(p =&gt; p.Order))
    {
      Html.RenderPartial(&quot;ProductImageForm&quot;, image); // &lt; Pass &#39;index&#39; to partial
      index++;
    }

I have some basic code to determine errors in my MVC application. Currently in my project I have a controller called `Error` with action methods `HTTPError404()`, `HTTPError500()`, and `General()`.  They all accept a string parameter `error`. Using or modifying the code below.
What is the best/proper way to pass the data to the Error controller for processing? I would like to have a solution as robust as possible.

    protected void Application_Error(object sender, EventArgs e)
    {
        Exception exception = Server.GetLastError();
        Response.Clear();

        HttpException httpException = exception as HttpException;
        if (httpException != null)
        {
            RouteData routeData = new RouteData();
            routeData.Values.Add(&quot;controller&quot;, &quot;Error&quot;);
            switch (httpException.GetHttpCode())
            {
                case 404:
                    // page not found
                    routeData.Values.Add(&quot;action&quot;, &quot;HttpError404&quot;);
                    break;
                case 500:
                    // server error
                    routeData.Values.Add(&quot;action&quot;, &quot;HttpError500&quot;);
                    break;
                default:
                    routeData.Values.Add(&quot;action&quot;, &quot;General&quot;);
                    break;
            }
            routeData.Values.Add(&quot;error&quot;, exception);
            // clear error on server
            Server.ClearError();

There seem to be different views on using &#39;using&#39; with respect to the std namespace.

Some say use &#39; `using namespace std`&#39;, other say don&#39;t but rather prefix std functions that are to be used with &#39; `std::`&#39; whilst others say use something like this:

    using std::string;
    using std::cout;
    using std::cin;
    using std::endl;
    using std::vector;

for all the std functions that are to be used.

What are the pros and cons of each?

Using std Namespace

I&#39;m working on an MVVM project, so I have folders in my project like Models, ViewModels, Windows, etc. Whenever I create a new class, Visual Studio automatically adds the folder name to the namespace designation instead of just keeping the project-level namespace. So, adding a new class to the ViewModels folder would result in the namespace, `MyProject.ViewModels` instead of just `MyProject`.

When I first encountered this, it annoyed me. My class names are pretty clear, sometimes even containing the name of the folder in them (e.g., `ContactViewModel`). I quickly found myself manually removing the folder name on the namespaces. I even tried at one point to create a custom class template (see [this question][1]), but I couldn&#39;t get that to work, so continued doing it manually.

I&#39;ve begun to wonder, though, if this convention exists for a good reason that I&#39;m just not seeing. I could see it being useful if you for some reason had lots of sets of identical class names organized into folders, but that doesn&#39;t seem like a particularly common scenario.

**Questions:**

 - Why is it common convention for namespace names to reflect folder structure?
 - Do you abide by this convention? Why?

Should I stop fighting Visual Studio&#39;s default namespace naming convention?

In my webproject I&#39;m using 4 resources files in my `App_GlobalResources` folder. One of them (`lang.resx`) has been created before my arrival on the project. It has the correct namespace (`WebApplication.App_GlobalResources`) and access modifier : `public`.

On the other hand, the three others Resource files that I just created have a different namespace (`Resources`) and `internal` access modifier, and I can&#39;t change it on the Resource File Form from Visual Studio because it&#39;s disabled. If I try to change it directly in the designer.cs file, the modifications are cancelled on the next save of the file.

It&#39;s not a critical bug but it can be misleading for the others developers on the project to find different namespaces and access modifiers for the resources files they will use.

Changing Resource files (resx) namespace and access modifier

I have an XML document with a default namespace indicated at the root.
Something like this:

    &lt;MyRoot xmlns=&quot;http://www.mysite.com&quot;&gt;
       &lt;MyChild1&gt;
           &lt;MyData&gt;1234&lt;/MyData&gt; 
       &lt;/MyChild1&gt; 
    &lt;/MyRoot&gt;

The XSLT to parse the XML does not work as expected because of the
default namespace, i.e. when I remove the namespace, everything works as
expected.

Here is my XSLT:

    &lt;xsl:stylesheet version=&quot;1.0&quot; xmlns:xsl=&quot;http://www.w3.org/1999/XSL/Transform&quot;
				xmlns:xs=&quot;http://www.w3.org/2001/XMLSchema&quot;&gt;
     &lt;xsl:template match=&quot;/&quot; &gt;
      &lt;soap:Envelope xsl:version=&quot;1.0&quot; xmlns:xsi=&quot;http://www.w3.org/2001/XMLSchema-instance&quot;  xmlns:xsd=&quot;http://www.w3.org/2001/XMLSchema&quot; xmlns:soap=&quot;http://schemas.xmlsoap.org/soap/envelope/&quot;&gt;
       &lt;soap:Body&gt;
         &lt;NewRoot xmlns=&quot;http://wherever.com&quot;&gt;
           &lt;NewChild&gt;
             &lt;ChildID&gt;ABCD&lt;/ChildID&gt;
             &lt;ChildData&gt;
                &lt;xsl:value-of select=&quot;/MyRoot/MyChild1/MyData&quot;/&gt;
             &lt;/ChildData&gt;
           &lt;/NewChild&gt;
         &lt;/NewRoot&gt;
       &lt;/soap:Body&gt;
      &lt;/soap:Envelope&gt;
     &lt;/xsl:template&gt;
    &lt;/xsl:stylesheet&gt;

I have created an Android project and added an external JAR (hessian-4.0.1.jar) to my project. I then added the JAR to the build path and checked it off in Order and Export.

Order and Export is ignored it seems, and all classes from the external JAR are missing at runtime.

Is there a trick to properly include the needed classes from an external JAR when building an Android application using the Eclipse plugin? I do not want to use ant or Maven.

I lost the solution of class-library, can I open `.dll` file which is created by `class-library`.  

How to open .dll files to see what is written inside?

In Visual Studio, there are at least three different types of class libraries you can create:

* Class Library (.NET Framework)
* Class Library (.NET Standard)
* Class Library (.NET Core)

While the first is what we&#39;ve been using for years, a major point of confusion I&#39;ve been having is when to use the .NET Standard and .NET Core class library types. I&#39;ve been bitten by this recently when attempting to [multi-target different framework versions][1], and [creating a unit test project][2].

So, what is the difference between *Class Library (.NET Standard)* and *Class Library (.NET Core)*, why do both exist, and when should we use one over the other?
