VS 2012 not highlighting Javascript code syntax errors - html

I'm a beginner to JavaScript and I am learning the fundamentals at the moment.
I have used visual studio before for code such as C# and VB and have a decent understand of how it highlights errors etc and shows build errors and what not.
Here is a small bit of code I've written in VS2012 in a HTML 5 file and the issue I have is it has 2 very obvious syntax errors however it does not highlight them and the page is allowed to run in both Firefox/Internet Explorer. The page obviously doesn't work and had I not known this syntax is wrong I wouldn't have been able to diagnose it.

Now I have looked at this topic : VS 2012 Syntax highlighting
I can't seem to make out from the above topic what exagtly I need to do to try that fix or even if that fix is relevant to my issue. The poster talks about what he's done but I don't understand how or what he's done.

Your code doesn't actually have any syntax errors.
Semicolons are optional, and variables do not need to be declared.
If you want to get errors for those, install Web Essentials and turn on JSHint.
(and add "use strict"; to your code)

How to Change Visual Studio Code Quick Fix Language?

I have a small problem with Visual Studio Code, I can't find place to change language of FIX tooltip(please check attached screen shot), I hate to use Polish lang in programs, a specialy when it's mixed with English UI. I can't find any solution online.
Configuration display language (after CTRL+Shift+P) is set to
{
// Defines VS Code's display language.
// See https://go.microsoft.com/fwlink/?LinkId=761051 for a list of supported languages.
"locale":"en" // Changes will not take effect until VS Code has been restarted.
Any suggestions?
The Quick Fix strings are part of the C# extension and not VS Code itself.
Assuming you're using ms-vscode.csharp, the issue you've described seems stuck in the issue tracker.
The workaround is to delete the OmniSharp localization files directory matching your Windows display language, in my case located here (your version will vary): C:\Users\%username%\.vscode\extensions\ms-vscode.csharp-1.19.1\.omnisharp\1.32.19\pl, after which the Quick Fix and debugging messages language will fall back to English.
Since I ran into the same problem with VS Code version 1.68.1, and the last answer by droopysinger is not applicable anymore, I dared to answer again.
I only used VS Code for C++ so the respective folder might change for your cases (see 'cpptools' in path).
However, navigate to folder
C:\Users\Username\ .vscode\extensions\ms-vscode.cpptools-1.10.7-win32-x64\bin\messages
and delete all folders for the different languages. From the next start of VS Code, the language for Quick Fix messages should fall back to English again.
Note: in my case there was no folder for english messages. After deleting said folders, the folder ...\messages was empty.

Devart LinqConnect for mysql A field initializer cannot reference the non-static field, method, or property

I couldn't solve this problem after linqConnect For Mysql generated entity of models for me. I thought devart is good software, without testing trial period, I purchased their license, but now I am facing this issue, I couldn't even get it working. please help
enter image description here
The the piece of code highlighted is "System.String.Empty", nothing is wrong here. A similar problem is discussed, for example, at Visual Studio 2015: Intellisense errors but solution compiles. Have you tried to build a project ignoring these fantom errors? Most likely, the build will succeed in this case. To avoid displaying such misleading "errors", choose "Build Only" droplist value (instead of "Build + IntelliSense") in the Error List window from your screenshot.

PHPStorm - show all errors on inspection

PHPStorm newbie question.
I'd installed PHPStorm yesterday and was very impressed. It identified countless small issues with my code, like referencing non-static classes statically - I loved that it highlighted the problems in my open PHP files. There was a bit long list in the "inspection results" section (I think) which identified errors in various groupings. Great!
Today I can't get it to identify any errors at all, other than "Typos". Same project.
Clearly I messed up a a configuration somewhere, but I'm pretty baffled as to where. I've been through the Preferences section for the last hour trying different things, but can't get it to work as before.
Any tips...?
Ben
Editor not doing proper code highlighting or not working inspections can be caused by the corrupted caches.
The solution is to do File | Invalidate Caches and restart the IDE.
Invalidating caches didn't worked for me.
In my case inspections were disabled because I had activated a wrong profile that wasn't checking PHP issues.
So be sure to check the used profile:

Set Start Program in Visual Studio Express

I want to run Nuint in Visual, so I set
<StartAction>Program</StartAction>
<StartProgram>$(NUNIT_PATH)\nunit.exe</StartProgram>
<StartArguments>Test.dll</StartArguments>
<StartWorkingDirectory>Test\bin\Debug</StartWorkingDirectory>
in my csproj file. But it stll does not work.
Those entries look correct for the project file. The most likely cause of the problem is that $(NUNIT_PATH) isn't properly set and hence gets evaluated to nothing. This would cause Visual Studio to look for nunit.exe in the Test\bin\Debug directory.
To test this try hard coding the full path to the nunit.exe binary into the file.
<StartProgram>C:\the\path\nunit.exe</StartProgram>
If this works then the NUNIT_PATH value isn't properly set.
Unfortunately the Express editions don't support the StartAction mechanism. See MSDN How to: Change the Start Action for Application Debugging.
I'm looking for alternatives though ;-)

What have you done to customize your IDE? [closed]

What tweaks / addins / themes do you have rigged up to make your IDE awesome? For example, in Visual Studio I color themes, CodeRush draws lines between braces, I always install and use the Consolas font and I have it setup to sync my settings across computers for when I change hotkeys and whatnot with the help of FolderShare.
Also, this isn't Visual Studio specific, please feel free to mention what you do with Emacs or Eclipse or whatnot as many of us use a few.
ReSharper 4.1 for Visual Studio 2008. It's a beautiful thing. It looks for all kinds of code errors, optimizations, etc. My code is cleaner thanks to this handy Visual Studio plugin.
Optimizing the IDE will be the first step. Resharper helps a lot but sometimes some simple macros are more than enough.
First things first. Change the font from the default crappy one. Then start fiddling with the 'Options' dialog box.
At the recommendation of a friend, I installed Visual Assist for Visual Studio 2008 -- it is awesome. I swear it can read my mind.
[Note: I have no affiliation with them -- just a very happy customer]
I've done a lot, but I really shouldn't have. So in the last few years, I've toned down the number of macros, custom key mappings, custom toolbars, etc. For the most part, I'm of the opinion that developers should get used to the default behavior and appearance of their IDE. Then when you need to work on your colleague's machine, you still know how to get around and manage to help them out. Not to mention that a whole slew of customizations will get broken or rearranged or otherwise reset when an update comes out.
That said, there are a few things that I still do every time I set up an IDE to work on... for example, setting the number of concurrent builds in Visual Studio to be 1, because that feature is so broken that nothing will compile correctly with any greater setting. Apart from that, being an ace with the default behavior will ultimately make you more efficient than spending hours tweaking the software to make it just a little more fluid.
I like CodeSmart VB6 and CodeSmart VS.NET from Axtools http://www.axtools.com/
for advanced syntax highlighting, drawing lines between parts of If..then..else..endif, Do While ... loop and all other constructs. It also has great code auditors and many add-in functions.
Vi plugin!!
I use Emacs. My .emacs file is only a few hundred lines long, but does customize settings based on my machine's hostname and operating system, so that I can use the same config file pretty much anywhere.
Colorization - Custom - White Text on GreyishBlack, Consolas Font
HotKeys - CTRL+SHIFT+ALT+Z (Attach to Process) probably some others too...
Addins - DPack, Coderush, GhostDoc.
Toolbars Off
All Windows set to collapsed
I am not doing presentations with this machine - If I was it would be barebones.
eclipse plugins make my ide exactly the way I want it of course.
eclipse plugin central
I kinda like the default setup of VS, I only make sure about Consolas as the editor font, and tabsize 2 (tabs to spaces), and change the color of numbers (red).
For Java development using Eclipse I have a few plugins that are indispensable. The MyEclipse Workbench adds a lot of functionality to most of the built-in modules. It makes it very easy to deploy an application to multiple application servers, and enhances a lot of the built-in editors. The PMD plugin is great for searching for potential code issues. As mentioned in a previous post today, the Ganymede plugin really helps to highlight log entries.
I dont care much for fancy visual addons, so I left my IDE (Visiual Studio) in the standard look (other than MS Reference Sans Serif font).
I usually change the color scheme to have a black background instead of white.
I use the Zenburn color scheme with Proggy Clean for a font. It's like a comfy chair for my eyes.
Nothing. I hate dealing with all the breakages that inevitably result from updates, etc. So, I adapt myself to my IDE instead.
I've using a combination of ViEmu and ReSharper with a dark theme.
Oh, and I also hide most of the toolbars and turn off the animations to try to speed things up.
Silver background, 8pt Consolas, disable all toolbars and set tab spacing to 3 spaces. :)
For Visual Studio
Most important - Resharper - I bought my own copy so I don't have to badger my employer about it.
Change the colourisation/font - choose whatever suits you
Optimisation (vote up Gulzar's post with the link in it)
Don't try and make the IDE do everything, just because you can. (Kind of ironic seeing I use emacs as well). I personally really dislike integrated source code management.
Change some defaut file associations so double clicking certain file types doesn't kick off Visual Studio
Aside from Resharper I've actually found most other beneficial thing is not customising the IDE, but customising yourself to learn the keyboard shortcuts. Start with the big gains like Ctrl -, Ctrl Shift -, Ctrl Shift V, Ctrl Alt L etc. etc. and then gradually learn the rest of the shortcuts in order of how often you'd use them
Rather than customizing the IDE, I customized my error messages. I have a macro that expands to a #pragma warning statement that generates a compile-time message in the same format as MSVC++. Visual Studio can parse the resulting warning, so a double-click on the message opens the offending file in the IDE and takes me right to the line in question.
I've used the macro:
To "bookmark" a section of code, so developers will be nagged to fix it each time they build.
Within #if blocks to test for various compile-time conditions.
In headers, to see who #includes them, and where.
From vim you can set the makeprg (make program) variable to a command that will build your project, and the errorformat variable to a scanf-style string that describes the format of the build errors. From there:
:make will build your project
:cl lists all of the errors that match errorformat
:cc takes to you the current error
:cn takes you to the next error
:cp takes you to the previous error.
Out of the box, vim sets makeprg and errorformat to work with make and gcc, and all of the commands are documented within vim's built-in help.
I do Java development in Eclipse. Here are some of the plug ins I find useful:
Mylyn - hides project elements not relevant to the current context.
eUML2 - UML editor.
FindBugs - Static analysis tool to find common bugs in Java.
Crap4J - Another static analysis tool.
EclEmma - Code coverage plug-in for unit tests.
Edit: I forgot one:
Disable the spellchecker. :)
In visual studio 2005 I do these:
Bind F11 to fullscreen mode
Enable a vertical line at 80 characters: HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\8.0\Text Editor\Guides = "RGB(196,196,196) 80" (Guides won't be present in the registry.)
Add the "Start Debugging", "Break All" and "Stop Debugging" buttons after the "Help" menu.
I am using Vim Cscope plugin.
Cscope is like 'ctags' on steroids and makes traversing code much easier.
I usually use it along with tags to find where a function is declared and then go directly to whatever code is calling this function.
I also use Vim's Rgrep plugin (recursive search) to search for files in the code hierarchy.
Create some basic macro such as printing bug fix code comments:
Public Sub WriteBugFix()
Dim TS As TextSelection = DTE.ActiveDocument.Selection
TS.Text = "'Edited for Bug Fixed By JK - " & Date.Now.ToShortDateString
End Sub
(This answer assumes the workstation is a GNU/Linux computer.)
Emacs makes an excellent IDE specifically because it can be greatly customized.
You customize Emacs by editing the .emacs file in your home directory. My .emacs is a symbolic link:
$ ln -s /home/bzimmerly/bin/emacs/emacs24/wbz.emacs.el .emacs
Since Emacs offers a variety of specialized major modes for program development and debugging, you can easily "roll your own" IDE design that works best for you. For example, when I'm programming in C or assembler, I like to have the left side running GDB mode, with the right side displaying the source being traced.
A little bit of LISP skill goes a long way to turning Emacs into a very powerful IDE. It is well worth the investment of time to learn how to use this powerful tool!
Finally, tools like Youtube are valuable places for learning how to do this. Just entering "Emacs as an IDE" on the Youtube search form will show videos of how people have modified Emacs for just such a purpose. There are videos on editing Python code, Javascript, Java, C, etc.
