Is there a way to list all the suggested Quick Actions for an open project in VS2017 (v15.3.3)?
I do not see any listed in the Error List window (even with "Build + IntelliSense" selected), though I do see other types of IntelliSense warnings such as CS warnings (e.g. CS1591).
(Quick Actions being the items that are marked in the gutter with a light bulb and accessed with either Alt +Enter or Ctrl+.)
Thanks to a response from the #VisualStudio twitter account, I've come across this MS Docs page that answers this question: https://learn.microsoft.com/en-us/visualstudio/ide/code-styles-and-quick-actions?utm_source=t.co&utm_medium=referral
It describes how to set code style preferences by opening the Tools > Options window and selecting Text Editor > C# / Basic > Code Style > General.
Here there are a list of the code style preferences. To see where they are suggested in one's own code the severity of each can be changed, say from "None" to "Suggestion" or "Warning". Then, during a build, the locations for the related style will be listed in the Build Output or Errors windows
This isn't exactly the same as what you're looking for, but could help you make changes much more quickly to the entire document, project, or solution:
When you try to apply a quick action (using Ctrl + .), you'll get a preview of the changes it will make. At the bottom of that preview is a button that says
"Apply to all occurrences in ..."
This will save you from having to go to every single occurrence in a certain scope and fixing it, which is what I've done for a couple of hours now :(

CLion 2016.2 helpfully detects potential errors in the file you're editing, which can be seen in the validation bar to the right of the code.
That's just a single file though, is there a way (like a tool window) to get a list of all such warnings in the whole project, or specific parts of it?
Bonus points if it also lists warnings and errors from the compiler, though that's less important, because the compiler output already includes any it found.
Yes, it is possible. The feature you are looking for is called the Inspector.
Do: Find Action... | Inspect Code. It will show a pop-up that will allow you to select the scope: file, whole project, custom, and the Inspection profile (you can choose the type of errors you want to see):
After clicking OK, this is an example of the output, that you can navigate with the mouse or with keyboard shortcuts:
In version 2017.2, I have it under Code | Inspect Code....
You can also right click a folder in Project view and select Inspect Code... there to be able to check only that folder.
I want to use code snippets in VSCode. But when I type, for example, for in javascript file, the Intellisense doesn't suggest snippet "for-loop" - I need to manually scroll the dropdown and select it. Is there any way to make VSCode to suggest snippets at first? Thank you!
UPD: I have found the person with same problem, but he has no answers - link
You need to use editor.snippetSuggestions config option with "top" value. Please, see Customizing IntelliSense article for more tips and tricks.
There is one more way to deal with this issue by setting
"editor.tabCompletion": true,
that way whenever there is a snnipet available it will use it automatically without even opening the list by using tab twice.
File > Preferences > Settings (Code > Preferences > Settings on Mac)
open "Editor" menu on the left
edit "editor.tabCompletion": true
more info: https://code.visualstudio.com/docs/editor/intellisense#_customizing-intellisense
Now that VS Code mostly abstracted away the settings.json file, you can do the instructions shown by Kavu, with this bonus tip:
go to Preferences > Settings
find the Search settings text input, at the top
type in "snippet"
The setting should be at the top of the result set:
Setting editor.snippetSuggestions to top only works for certain snippets: for but not foreach. With top, the snippet does appear higher in the completion list, but for some reason the keyword version is what is highlighted, with the snippet option scrolled out of view (and the scrollbar quickly fades, giving the impression there's nothing hidden)
The editor.tabCompletion to true approach works for both for and foreach.
Apologies upfront if this is a silly question, but it's annoying me to no end and I can't figure it out.
I'm using Visual Studio 2013 Professional, and I usually code in C# where when using the Intellisense, when I press Enter to select a method or something it adds my selection and I can continue typing on the same line.
But at the moment I'm working on a project which is in VB.NET, and when I use the Intellisense in the same way it puts my cursor in the next line, i.e. I press Enter to select whatever, it adds my selection and starts a new line, so I have to press the Backspace to go back to the previous line. It's so annoying!
Is there a way to change this behaviour so the cursor doesn't go to the next line? I've looked at the settings available in Tools > Options but can't figure it out, and searching Google for anything similar hasn't been successful.
Found it here (paragraph List Members)
You have toggled to suggestion mode instead of completion mode.
You can also change to suggestion mode, in which only the text you type is inserted into the code. For example, if you enter an identifier that is not in the list and press TAB, in completion mode the entry would replace the typed identifier. To toggle between completion mode and suggestion mode, press CTRL+ALT+SPACEBAR or click Edit/IntelliSense/Toggle Completion Mode.
So, either use TAB/SPACEBAR (as I said in the comment) or press CTRL+ALT+SPACEBAR to switch back to completion mode.
EDIT: I've found out that whenever you type Stri (String will show highlighted in the list now) and you press . (dot) it will autocomplete and stay at the same line.
I think your way of doing this in C# isn't possible in Visual Basic.
I had the same problem and discovered that Auto list members was not enabled on my machine. It's under Tools > Options > Text Editor > Basic > General. This gave me the intellisense I was looking for.
Simple thing which can be used when you face this kind of issue is to press
tab key instead of Enter key when the IntelliSense provided me prediction list.
I hate to ask such simple questions, but nothing I found so far helped me...
So, I've recently started using IntelliJ instead of Eclipse and there are 2 things that really bothers me...
1.) size of javadoc popup window - ok, so I finally get this little guy to pop-up whenever I need it, but it's so small I have to use scroll every single time... and that's pretty anoying when I'm working with unknown libraries...
2.) tabs == spaces - maybe some of you like this, but I don't... Eclipse was treating tabs as tabs and not spaces... I tried to change settings but with no result... or is that maybe connected with project I'm working on? (meaning, if, at the start of a project, setting were such that tabs == spaces and now changes are not applied to it)
Sorry for stupid question but, as I said, nothing I found so far helped me...
1) Just resize the window with your mouse. It will retain the size the next time it opens. You can also click on the gear icon in the upper right corner and adjust the font size. Again, it will retain the size on subsequent use.
2) I'm assuming you make the change to the "Use Tab Character" option on the "Tabs and Indents" tab for all file types and saved the Code Style. After that, you need to run the Reformat Code action (Ctrl+Alt+L or Code > Reformat Code from the menu or Reformat Code from the context menu (i.e. right-click) in The Project Tool window or Navigation Bar). IDEA retains the previous formatting (so spaces in this case) until you run a reformat on the project (or a part of it).
If you have multiple projects already created, for each one, you will need to go into File > Settings > [Project Settings] > Code Style and set the Scheme (and then do a reformat). While the Scheme definition is saved IDE wide, the scheme to use is set per project (which makes sense since an Apache Open Source project you are working on may have different code style requirements than the projects you do at work vs the ones you do for fun).
Finally, you will also want to go into File > Other Settings > Default Settings > [Template Project Settings] > Code Style and make sure your saved code style scheme (with the use tab option) is set so that new projects use that scheme when they are created.
In our code base there are a few very long methods (several pages worth of code). When reading the code, it would sometimes be good to be able to see the name of the method the current line belongs to, without paging up to the beginning of the method. Is this possible in Intellij IDEA? I am using Intellij IDEA 7.0.3.
You can use View | Context Info (Alt+Q, Ctrl+Shift+Q on Macs). It will display a pop-up on the top of the editor with the current context information (class/method signature).
IntelliJ 2018
This is shown by default at the bottom.
Unfortunately, the method is shown only by name (not including the parameters). If a method is overloaded you won't know for sure where you are.
If you want to move it from bottom to top, go to File > Settings... > Editor > General > Breadcrumbs > check Top:
In the structure panel select the "Autoscroll from source" option.
This way when you place the cursor inside any method the structure panel will show which method you're in.
Intellij now has support for breadcrumbs. Go to settings > appearance and tick "Show breadcrumbs". In this way you can view class/method name without Alt+Q.
For some reason (Alt-Q) wasn't consistent in Android Studio for me. I find (Ctrl-F12) to be pretty satisfactory for this purpose (Navigate|File Structure) though it can be a little laggy in larger files. And by pressing the hotkey again it will populate the list with all the inherited methods as well.
