Toggle it on/off with: Edit &gt; Advanced &gt; View white space

The default hotkey is usually &lt;kbd&gt;ctrl+E,S&lt;/kbd&gt; (I think this is for General or C# developer settings)

If you use Resharper, you may find you need to use &lt;kbd&gt;ctrl+R,ctrl+W&lt;/kbd&gt; (this may also apply for C++ developer settings)

_(**Note** that the hotkey may be **different** for different key binding schemes, and can be customised in Tools &gt; Options &gt; Keyboard. Also, Addins and Extensions (e.g. Resharper) may modify them or add their own equivalents. But the bound key will be displayed on the above menu so it&#39;s easy to determine what the hotkey is on your PC)_

This is a very useful feature as it allows you to quickly check longer code sections to see which logic branch that code belongs to.

To toggle this:

Edit-&gt;Advanced-&gt;View White Space or use short cut (&lt;kbd&gt;CTRL+E&lt;/kbd&gt; + &lt;kbd&gt;S&lt;/kbd&gt;)


I&#39;m looking for an algorithm that compares two RGB colors and generates a value of their similarity (where similarity means &quot;similar with respect to average human perception&quot;).

Any ideas?


**EDIT**:

Since I cannot answer anymore I decided to put my &quot;solution&quot; as an edit to the question.

I decided to go with a (very) small subset of true-color in my app, so that I can handle comparison of colors by my own. I work with about 30 colors and use hard-coded distances between them.

Since it was an iPhone app I worked with objective-C and the implementation is more or less a matrix representing the table below, which shows the distances between the colors.

I have extracted image uri, now I would like to open image with Android&#39;s default image viewer. Or even better, user could choose what program to use to open the image. Something like File Explorers offer you if you try to open a file.

see these dotted lines there on every indent...  
How do I turn it off?  
  
I must have accidentally hit some keyboard shortcut but I can&#39;t find this anywhere in the settings.  
  
Sorry, this is a really dumb question, but these lines really bother me and I didn&#39;t know where else to turn :)

I&#39;ve installed Visual Studio 2010 (fresh install), then applied the SP1. Now I&#39;ve tried to install the silverlight 4 tools, but i&#39;m getting a strange error message : 

&quot;Visual Studio 2010 or Visual Web Developer Express 2010 or Visual Phone Developer Express 2010 that matches the language version of Silverlight Tools 4 must be installed before installation of Silverlight Tools can continue.  Silverlight Tools is available in other languages at &lt;A HREF=&quot;http://go.microsoft.com/fwlink/?LinkId=177432&quot;&gt;http://go.microsoft.com/fwlink/?LinkId=177432&lt;/A&gt;. 

The Visual Web Developer feature for Visual Studio 2010 must be installed before installation can continue.&quot;

I&#39;ve triple checked and there&#39;s no language conflict. Browsing the web, some guys have the same error, but there are some MSDN posts that say that with SP1 you don&#39;t need to install silverlight tools because they&#39;re already bundled with SP1, but that&#39;s not the case here, I don&#39;t have any project templates in VS for silverlight, and the tools aren&#39;t installed. Any ideas??

I have javascript files that I need them to be saved in UTF-8 (without BOM), every time I convert them to the correct format in *Notepad++*, they are reverted back to UTF-8 with BOM when I open them in Visual Studio. How can I stop VS2010 from doing that?

Another question, is UTF-8 without signature in Visual Studio the same as UTF-8 without BOM?

I am developing a project in VS2010 and am able to view my site locally via IIS Express.  I would like to enable external access over the network.

All my research has sent me to this blog entry: &lt;http://blogs.iis.net/vaidyg/archive/2010/07/29/serving-external-traffic-with-webmatrix-beta.aspx&gt;, which is helpful but does not seem to show how to configure bindings for a project started in visual studio (I cannot find the screen in the screenshots, and I have edited binding info in applicationhost.config, but it does not seem to be reflected when I run the site from visual studio).

I have a WCF Data Service project built with Visual Studio 2010, which was working fine. All of a sudden, it didn&#39;t compile anymore. It was giving me messages like:

&gt; Error 7   The type or namespace name &#39;Services&#39; does not exist in the namespace &#39;System.Data&#39; (are you missing an assembly reference?)    C:\U...s\Visual Studio 2010\Projects\...\DataService.cs ...

&gt;
&gt;Error  12  The type or namespace name &#39;DataService&#39; could not be found (are you missing a using directive or an assembly reference?)

How can I fix it?

Why does Visual Studio 2005 generate the `.pdb` files when compiling in release?  I won&#39;t be debugging a release build, so why are they generated?

Release generating .pdb files, why?

What I want to do is very simple, yet can&#39;t find the way to do it.  
In my projects I have several .bat files (I know, I&#39;m old) the perform some tasks like running SqlMetal, etc. 

I just want to right-click the file and select &quot;run&quot; or something so the bat is executed. **How do I do it?**

_Note: I know I can use Tools -&gt; External Tools, but it&#39;s not what I&#39;m looking for_


How to run a .bat from inside the IDE

I&#39;m not very familiar with post-build events, so I&#39;m a little confused as to what&#39;s going wrong with my program. When compiling in visual studio 2010, I get the following:

    The command &quot;xcopy C:\Users\Me\Path\Foo.bar\Library\dsoframer.ocx C:\Users\Me\Path\Foo.bar\bin\Debug\ /Y /E /D
    xcopy C:\Users\Me\Path\Foo.bar\ApplicationFiles C:\Users\Me\Path\Foo.bar\bin\Debug\ /Y /E /D
    xcopy C:\Users\Me\Path\url\ C:\Users\Me\Path\Foo.bar\bin\Debug\ /Y /E /D
    rmdir /S /Q C:\Users\Me\Path\Foo.bar\bin\Debug\.gwt-tmp&quot; exited with code 4.	

The program *appears* to run fine, despite this error, but I don&#39;t want to just ignore this issue and hope nothing bad happens. Strangely, this line started out as only a single command (the first xcopy) but as I continued to compile the project (fixing other problems, mostly references) the error message expanded larger and larger. Any idea what could be going on?

Edit: Here are the postbuild events that seem to be failing --

    xcopy $(ProjectDir)Library\dsoframer.ocx $(TargetDir) /Y /E /D
    xcopy $(ProjectDir)ApplicationFiles $(TargetDir) /Y /E /D
    xcopy $(SolutionDir)com.myUrl.gwt\www $(TargetDir) /Y /E /D
    rmdir /S /Q $(TargetDir).gwt-tmp

When I try to open my Visual Studio project I get the following error:

&gt;Asp.Net has not been registered on the webserver you need to manually configure your webserver for Asp.net 4.0.

**Update:**  
Nevermind I fixed it:
  
I just repaired .Net Framework 4.0 and the issue was resolved.

In my VS2010, when I build my solution, I have over 100 warnings in the file **Microsoft.Common.Targets**. When I try to build, publish or run my programs, I get just the warnings, but the moment I double click it to get more info, the Microsoft.Common.Targets pops up and then I get all on the warnings.

This file Microsoft.Common.Targets is part of the .net framework and has the MSBuild in-built targets, etc. And it has the approperiate schema associated in the properties window.

Some example warnings (2 out of 100) :

    Warning    2    The element &#39;PropertyGroup&#39; in namespace &#39;http://schemas.microsoft.com/developer/msbuild/2003&#39; has invalid child element &#39;CustomBeforeMicrosoftCommonTargets&#39; in namespace &#39;http://schemas.microsoft.com/developer/msbuild/2003&#39;. List of possible elements expected: &#39;Property&#39; in namespace &#39;http://schemas.microsoft.com/developer/msbuild/2003&#39;.    C:\WINDOWS\Microsoft.NET\Framework\v3.5\Microsoft.Common.targets    22    10    Miscellaneous Files
    Warning    3    The element &#39;PropertyGroup&#39; in namespace &#39;http://schemas.microsoft.com/developer/msbuild/2003&#39; has invalid child element &#39;_OriginalConfiguration&#39; in namespace &#39;http://schemas.microsoft.com/developer/msbuild/2003&#39;. List of possible elements expected: &#39;Property&#39; in namespace &#39;http://schemas.microsoft.com/developer/msbuild/2003&#39;.    C:\WINDOWS\Microsoft.NET\Framework\v3.5\Microsoft.Common.targets    60    10    Miscellaneous Files

Why is this file suddenly in my editor, when it is not part of my project, and how to tell visual studio to ignore this framework file while building.

I&#39;m reasonably new to OS X, but I&#39;m familiar with Vim from using it in various *nix systems. I&#39;ve seen many people recommend running MacVim over Vim in the terminal. Can anyone tell me what differences there are between MacVim and regular Vim?

What is the difference between MacVim and regular Vim?

I am a long time emacs user learning Vim. Emacs lets me navigate in the mini-buffer (where I issue commands like C-x C-s) using the same navigation keyboard shortcuts as in any other buffer. For example, I can navigate forward one character using C-f, even while in the mini-buffer. I could also use the arrow keys, but they are too far away. 

Is there any keyboard shortcut to navigate in Vim&#39;s command mode (:), without using the arrow keys -- equivalent to emacs C-f, C-b? Thanks.

I&#39;ve installed Sublime 2 on Ubuntu using a PPA repository and update it via this native Ubuntu mechanism, so it just annoys me to see &quot;A new version is available...&quot; every time I start Sublime. I&#39;ve found nothing searching for &quot;update&quot; in Sublime configuration file. Where can I disable the notification?
