For now, you have to go through the issues individually.
There&#39;s an [existing request](http://youtrack.jetbrains.net/issue/RSRP-150247) to batch-apply fixes to all similar issues selected in the &quot;Inspection Results&quot; tool window.

Code Cleanup does batch-remove certain issues in any given scope but it&#39;s quite limited in the number of fixes it can apply, compared to the number of code issues that ReSharper is able to detect.

Click into a redundant qualifier, alt+enter, then choose from the context menu that lets you fix the issue however thoroughly you&#39;d like.

Yes, you can use ReSharper&#39;s &quot;[Cleanup Code][1]&quot; to remove redundant qualifiers (amongst other things). This is available from the context-menu when you right-click files, projects and folders in the Solution Explorer window. Code Cleanup will run over all the selected files, reformatting and fixing common issues - it is also customizable.

This is available (in part) in the latest build. If you go to a specific issue in the code editor, click the lightbulb the fix option now has a submenu for some issues that can be applied to the entire solution. Would be cooler if it was available from the Code Issues window, but still a great improvement.

How do you display the information from a database table in a table format on a webpage? Is there a simple way to do this in django or does it require a more complicated approach. More specifically, how do you pretty much port over the columns and rows in a database table to a visual table that can be seen from a url?

I just noticed that java.util.Observable is a concrete class. Since the purpose of Observable is to be extended, this seems rather odd to me. Is there a reason why it was implemented this way?

I found [this article][1] which says that 

&gt; The observable is a concrete class, so the class deriving from it must be determined upfront, as Java allows only single inheritance.

But that doesn&#39;t really explain it to me. In fact, if Observable were abstract, the user would be forced to determine the class deriving from it.

Why is java.util.Observable not an abstract class?

e.g.
alt enter -&gt; context menu -&gt; Find all &#39;Redundant name qualifier&#39; issues -&gt;
but now in the new window that lists all those issues in my project, is there a way to fix them all ? (rather than go through them individualy)

<p>e.g.
alt enter -> context menu -> Find all 'Redundant name qualifier' issues ->
but now in the new window that lists all those issues in my project, is there a way to fix them all ? (rather than go through them individualy)</p>
<p>ta.</p>


This is pretty simple but I&#39;m at a loss:
Given this type of data set:
 
    UserInfo(name, metric, day, other_metric)
and this sample data set:

    joe  1 01/01/2011 5
    jane 0 01/02/2011 9
    john 2 01/03/2011 0
    jim  3 01/04/2011 1
    jean 1 01/05/2011 3
    jill 2 01/06/2011 5
    jeb  0 01/07/2011 3
    jenn 0 01/08/2011 7

I&#39;d like to retrieve a table that lists metrics in order(0,1,2,3..) with the total number of times the count occurs. So from this set, you&#39;d end up with:

    0 3    
    1 2    
    2 2    
    3 1
   
I&#39;m grappling with the LINQ syntax but am stuck on where to put a groupby and count...
any help?

POST Edit: I was never able to get the posted answers to work as they always returned one record with the number of different counts. However, I was able to put together a LINQ to SQL example that did work:

```
var pl = from r in info
		 orderby r.metric    
		 group r by r.metric into grp
		 select new { key = grp.Key, cnt = grp.Count()};
```

This result gave me an ordered set of records with &#39;metrics&#39; and the number of users associated with each. I&#39;m clearly new to LINQ in general and to my untrained eye this approach seems very similar to the pure LINQ approach yet gave me a different answer.

LINQ with groupby and count

I have a test like this:

&lt;!-- language: lang-csharp --&gt;

        [TestCase(&quot;~/page/myaction&quot;)]
        public void Page_With_Custom_Action(string path) {
            // Arrange
            var pathData = new Mock&lt;IPathData&gt;();
            var pageModel = new Mock&lt;IPageModel&gt;();
            var repository = new Mock&lt;IPageRepository&gt;();
            var mapper = new Mock&lt;IControllerMapper&gt;();
            var container = new Mock&lt;IContainer&gt;();

            container.Setup(x =&gt; x.GetInstance&lt;IPageRepository&gt;()).Returns(repository.Object);

            repository.Setup(x =&gt; x.GetPageByUrl&lt;IPageModel&gt;(path)).Returns(() =&gt; pageModel.Object);

            pathData.Setup(x =&gt; x.Action).Returns(&quot;myaction&quot;);
            pathData.Setup(x =&gt; x.Controller).Returns(&quot;page&quot;);

            var resolver = new DashboardPathResolver(pathData.Object, repository.Object, mapper.Object, container.Object);

            // Act
            var data = resolver.ResolvePath(path);

            // Assert
            Assert.NotNull(data);
            Assert.AreEqual(&quot;myaction&quot;, data.Action);
            Assert.AreEqual(&quot;page&quot;, data.Controller);
        }

`GetPageByUrl` runs twice in my `DashboardPathResolver`, how can I tell Moq to return `null` the first time and `pageModel.Object` the second?

I have a field in my database that holds a DateTime?. I would like to sort the results so that the NULLs show up at the top, then descending by DateTime, e.g.,

    null
    null
    2012-04-01
    2012-01-01
    2011-09-04

The reason is that I am looking at expiration dates, though some entries do not expire.


Linq OrderByDescending, null first

In this query:

    public static IEnumerable&lt;IServerOnlineCharacter&gt; GetUpdated()
    {
        var context = DataContext.GetDataContext();
        return context.ServerOnlineCharacters
            .OrderBy(p =&gt; p.ServerStatus.ServerDateTime)
            .GroupBy(p =&gt; p.RawName)
            .Select(p =&gt; p.Last());
    }

I had to switch it to this for it to work

    public static IEnumerable&lt;IServerOnlineCharacter&gt; GetUpdated()
    {
        var context = DataContext.GetDataContext();
        return context.ServerOnlineCharacters
            .OrderByDescending(p =&gt; p.ServerStatus.ServerDateTime)
            .GroupBy(p =&gt; p.RawName)
            .Select(p =&gt; p.FirstOrDefault());
    }

I couldn&#39;t even use `p.First()`, to mirror the first query.

Why are there such basic limitations in what&#39;s otherwise such a robust ORM system?

LINQ To Entities does not recognize the method Last. Really?

I use: Visual Studio 2010 Ultimate, Resharer 6.

In ReSharper&#39;s options i choose Visual Studio keyboard sheme and click Apply Sheme:

After that some shortcuts are not assigned, such as: Go to Declaration, Go to implementation, Find Usages, Complete symbol, etc:

Try 

 - Tools -&gt; Options, Environment -&gt; Keyboard -&gt; Reset
 - Import and Export Settings, re-import C# developer settings
 - devenv /reset

Nothing helped.

Configure shortcuts manually is not desirable.

Is there a way to define regions in CSS file just like regions in C#? 

Like in C# you define regions as follows

    #region My Region
    //your code here
    #endregion

My problem is I don&#39;t want to use separate CSS files for my asp.net project but I also want to organinze so I can define specific sections like one for Master Page CSS and one for FormUser and so forth so it is easy to troubleshoot when needed. Is it possible?

While I was trying to Update my Project I was making - I got an error for the first time I&#39;ve seen:

&gt; &#39;An error occurred while signing: SignTool.exe not found.&#39;

I&#39;ve never seen this before, So I looked up that SignTool.exe is what signs my project for ClickOnce Deployment.

I also read that is it a part of Windows SDK - but when I looked to find where SignTool.exe is - I saw it right there!

      C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Bin

I saw no problem, and I&#39;ve always published my Project all the time - I&#39;m on Version 68. But this is the first time I&#39;ve seen this - I didn&#39;t touch any options that would do this.

Any help?

In VS2010 there is an option to generate debug info for exes/dlls under _linker_ but no such option under _librarian_ for libs. Is the debug info embedded in the static library?

There is an option in the _C/C++_ properties for _Program Database File Name_ for libs, exes, and dlls. By default it goes into my intermediate directory and is named the project name for libs, but is named _vc$(PlatformToolsetVersion).pdb_ for exes/dlls. What&#39;s the pdb from this option and how does it differ from the pdb in the linker option?

If I am supplying a library with libs and headers how do I supply debug symbols to a user of my library?

I primarily use Visual Studio and ReSharper (R#) for development and have excellent working knowledge of R#. I want to leverage that knowledge in IntelliJ IDEA (with my personal Java adventures) without having to learn the IDEA keymap scheme. IDEA has a Visual Studio keymap but that mainly updates such key bindings as Find (Ctrl + F) and Replace (Ctrl + H) etc. Because Visual Studio doesn&#39;t have built-in capabilities like &quot;Inspect This...&quot; etc. (the kinda stuff provided by R#), those IntelliJ keybinding in Visual Studio keymap are merely a dump of IDEA&#39;s.

In VS.NET, ReSharper comes with two keymaps, IDEA and Visual Studio. I&#39;ve been using the Visual Studio keymap since R# 5 and really would like to have a keymap in IntelliJ idea that actually is a combination of the Visual Studio IDEA keymap and R# Visual Studio keymap. This combinational keymap is what I am calling Visual Studio ReSharper (R#) keymap for IntelliJ IDEA.

I&#39;d appreciate if someone can share thier keymap if they have created one that&#39;s close to the stated description. If JetBrains is hearing, how about bundling an additional keymap scheme with IntelliJ that&#39;s essentially a combination of Visual Studio scheme (in IntelliJ IDEA) and ReSharper Visual Studio scheme (in VS.NET)?

Visual Studio ReSharper Keymap for IntelliJ IDEA

In my code I need to use an `IEnumerable&lt;&gt;` several times, resulting in the ReSharper error of &quot;Possible multiple enumeration of `IEnumerable`&quot;.

Sample code:

    public List&lt;object&gt; Foo(IEnumerable&lt;object&gt; objects)
    {
        if (objects == null || !objects.Any())
            throw new ArgumentException();
            
        var firstObject = objects.First();
        var list = DoSomeThing(firstObject);        
        var secondList = DoSomeThingElse(objects);
        list.AddRange(secondList);
        
        return list;
    }

 - I can change the `objects` parameter to be `List` and then avoid the possible multiple enumeration but then I don&#39;t get the highest object that I can handle.  
 - Another thing that I can do is to convert the `IEnumerable` to `List` at the beginning of the method:   

--- 
     public List&lt;object&gt; Foo(IEnumerable&lt;object&gt; objects)
     {
        var objectList = objects.ToList();
        // ...
     }

But this is just **awkward**.

What would you do in this scenario?

Handling warning for possible multiple enumeration of IEnumerable

I&#39;ve been using [ReSharper][1] for a while now and sometimes it suggests that I invert the `if`. I guess an example would be a better explanation of my situation:

    public void myfunction(int exampleParam){
        if(exampleParam &gt; 0){
            //Do something with form controls for example.
        }
    }

Now ReSharper suggests that I invert the `if` to this:

    public void myfunction(int exampleParam){
        if(exampleParam &lt;= 0)
            return;
        //Do something with form controls for example
    }

Does this &quot;improve&quot; performance somehow? Or is it just aesthetic?

Does inverting the &quot;if&quot; improve performance?

I&#39;m running a beta version of ReSharper, and it&#39;s giving me warnings for the following code:

    int id;
    // ...
    DoSomethingWith(id.ToString());

The warning is on the `id.ToString()` call, and it&#39;s telling me &quot;Specify a culture in string conversion explicitly&quot;. I understand the warning, and I know how to fix it -- just change the code to the much more unwieldy `id.ToString(CultureInfo.InvariantCulture)`.

But my question is: is that necessary? I mean, obviously it&#39;s important to specify the culture when you&#39;re using types like `DateTime` (different cultures have different date formats) and `Double` (different characters used for the decimal point). But `Int32.ToString()`, at least in the en-US and invariant cultures, doesn&#39;t add any formatting at all. No commas, no decimal points, no dollar signs, nothing. So what would there be to vary by culture?

Are there some cultures that actually *add* some sort of formatting when you call the parameterless `Int32.ToString()`? Or is this a bug in the ReSharper beta, and this warning really isn&#39;t applicable to `Int32` (in which case I&#39;ll file a ReSharper bug report)?
