Sometimes I have the need to try: A code example or a variant of it.
This is necessary to test a new functionality or to test its implementation or performance.
The code can be very long.
So I need some way to quickly comment on the code with
/*
* mi código
* …
* /
O con:
//
// mi código
// …
//
When the code is very long, it is cumbersome to do: Select all the code you do not want to run and discuss, Write or insert the code you want to try, Do tests or whatever...
Now...
Select and comment on the new block of code.
Search and select the previous code, and Uncomment.
Do tests or whatever...
And so I need to do it many times since I'm recycling, as I have been thirty years since I program almost nothing.
Is There any way or trick to do it quickly?
If you're in vs code just enter ctrl + /. For VS studio 2017 ctrl + k + u.
If you are using visual studio as your IDE you can use the following:
Ctrl+K+C to commment and Ctrl+K+U to uncomment.
If using pycharm or VS Code:
Use Cntrl+/ to comment and uncomment.
In Visual Studio 2019 Preview
Comment : Ctrl + k and Ctrl + c
Uncomment : Ctrl + k and Ctrl + u
You can select all lines in the code cell with Ctrl+A (Windows/Linux) or Cmd+A (Mac)
Then press Ctrl+/ (Windows/Linux) or Cmd+/ (Mac) to uncomment
Press / again to comment
Trick:
When We have a very long code and need to comment and uncomment quickly:
ADD at the beginning of the BLOCK:
/*//TODO: Comment or uncomment this block.
Remove an inclined bar at the beginning of the line to uncomment.
Add an inclined bar at the beginning of the line to comment. '
And add at the end of the block
/*/
The tag TODO: It shows you in tasks the message,
so you can locate it quickly.
In Addition the commented code can collapse in the [+] when it is commented.
Commented Code:
[+]/*//TODO: Add a "/" at startup to uncomment.
This block does something.
...
Code 100000.0 lines.
...
/*/
Uncommented Code:
//*//TODO: Remove a "/" at startup to comment.
This block does something.
[+] ...
Code 100000.0 lines.
...
/*/
I Didn't know how to tell everybody, like I do.
I Hope it's useful.

I'm using visual studio 2010 , (with resharper installed if it helps) :
is there any shortcut of commenting a code via /* lalala */ and not via //lalala ?
I already know that CTRL K C comment a code but it comments it with //
Is there anyway of commenting a code via /**/ ?
There is ReSharper | Edit | Comment with block comment which makes exactly what you need.
Default shortcut for this - Ctrl+Shift+/
If you would like to uncomment it, put the caret on any place in the comment and hit Ctrl+Shift+/ once again. The same behavior is available for ReSharper | Edit | Comment with line comment (Ctrl+Alt+/) as well.
If you only select lalala and then hit CTRL K + C, it will uncomment lalala with /* */ (for example when lalala is a parameter in a function, just double click it and hit CTRL K+C.
Found it in resharper :
you can add :
I couldn't find such feature in VS's shortcut list. Is there anyway?
If you want to copy a line, simply place cursor somewhere in that line and hit CTRL+C
To cut an entire line CTRL+X
#Sean found what I was looking for:
To disable this default behavior remove the checkmark (or check to re-enable)
Apply cut or copy commands to blank lines when there is no selection
Accessed from the menu bar: Tools | Options | Text Editor | All languages
You can also enter copy into the options search box for quicker access
[Tested in VS2008, 2010, 2017]
Clicking the line 3 times does the trick
If you have ReSharper you could use
Ctrl + W
- Extend Selection
Sidenote: You may have to use it multiple times depending on the context of your present text cursor position.
If you click once on the row number the entire row will be selected.
If you want to select a line or lines you can use the combination of ctrl + E then U. This combination also works for uncommenting a complete line or lines. This combination looks somewhat strange to work with, but it will get habituated very soon :)
You can also use Ctrl + X to cut an entire line. Similarly, you can use Ctrl + C to copy an entire line.
As long as you don't have anything selected, these commands will work on the entire line.
Clicking anywhere on the line and (CRTL + C) will copy entire line.
Clicking three time in quick succession also selects entire line.
There is a simple way of doing it, simple use Home or End button to reach the start or end of line, and then use home + shift or end + Shift depending on where your cursor is. Hope it helps.
Use the following:
Shift + End If cursor is at beginning of line.
or
Shift + Home If cursor is at the end of the line.
Alternatively, if you use resharper, you can also use the following
Ctrl + w while the cursor is positioned on the line you want to select
This won't solve the problem for Visual Studio, but if you're using Visual Studio Code you can use CTRL+L to select the line your cursor is currently on.
(If you're using Visual Studio, this will cut the line you're currently on—which may also be useful, but wasn't the question.)
Other answers require either using a mouse or hitting more than one combination.
So I've created a macro for those who want a VSCode-like Ctrl+L behaviour. It can select multiple lines, and that's useful for moving blocks of code.
To use it, install Visual Commander extension for macros: https://marketplace.visualstudio.com/items?itemName=SergeyVlasov.VisualCommander
Then create a new command, select C# as a language and paste this code:
using EnvDTE;
using EnvDTE80;
public class C : VisualCommanderExt.ICommand
{
public void Run(EnvDTE80.DTE2 DTE, Microsoft.VisualStudio.Shell.Package package)
{
var ts = DTE.ActiveDocument.Selection as EnvDTE.TextSelection;
if (!ts.ActivePoint.AtStartOfLine)
ts.StartOfLine();
ts.LineDown(true, 1);
}
}
Now you can assign a desired shortcut in preferences:
Tested in VS 2022.
You can use CTRL + U . This shortcut is use also for uncomment.
You can change the shortcut on this feature. Go to Tools->Options->Environment->Keyboard->Edit.UncommentSelection and assign CTRL+W (same as Resharper) or you can use what shortcut do you want.
If you want to select full row Ctrl E + U
Just click in the left margin.
If you click in the margin just left of the Outline expansions [+][-]
it will select the row.
You can also just click and drag to select multiple lines.
Necvetanov eluded to this in his answer above about clicking on the line number.
This is right...but it just happens that the line number is in the margin.
Here is a whole list of the keyboard shortcuts Default keyboard shortcuts in Visual Studio
a work around for this:
ctrl+d = duplicate line
ctrl+l = copy line
ctrl+v = paste copied text
You can enter, home then shift + end as well. What it will do is take you to the beginning of line then select the whole line till end. Or alternatively first enter end then shift + home
You can set a bind to the Edit.ExpandSelection command:
In the options. Click the shortcut until it selects the whole line.
The screenshot above is from the Edit > Advanced menu in Visual Studio 2022. I set this Alt+E, E shortcut myself and I don't remember if it's originally set to something or not.
Simply by clicking on the line number that's being shown on the left in vs-code. just a single click and a line will get selected.
In Mac, it is ⌘+L.
But if you have some specific conflicting keybindings, this won't work. In my case the VSCode Live Server extension auto registered a couple of bindings for these keys. I removed them and it worked.
I assigned a shortcut key to the following functionality. I press the shortcut until it selects the whole current line:
Edit.SubwordExpandSelection
How can I automatically indent source code in Visual Studio 2010?
I have used Ctrl + K, Ctrl + F, but it does not work; is there any other way/plugin to do this?
Ctrl+E, D - Format whole doc
Ctrl+K, Ctrl+F - Format selection
Also available in the menu via Edit|Advanced.
Thomas
Edit-
Ctrl+K, Ctrl+D - Format whole doc in VS 2010
In 2010 it is Ctrl+k, Ctrl+d. See image below.
In Visual Studio 2010
Ctrl +k +d indent the complete page.
Ctrl +k +f indent the selected Code.
For more help visit : http://msdn.microsoft.com/en-us/library/da5kh0wa.aspx
every thing is there.
In 2010 it is ctrl +k +d for indentation
Also, there's the handy little "increase indent" and "decrease indent" buttons. If you highlight a block of code and click those buttons the entire block will indent.
I have tried both ways, and from the Edit|Advanced menu, and they are not doing anything to my source code. Other options like line indent are working. What could be wrong? – Chucky Jul 12 '13 at 11:06
Sometimes if it doesnt work, try to select a couple lines above and below or the whole block of code (whole function, whole cycle, whole switch, etc.), so that it knows how to indent.
Like for example if you copy/paste something into a case statement of a switch and it has wrong indentation, you need to select the text + the line with the case statement above to get it to work.
It may be worth noting that auto-indent does not work if there are syntax errors in the document. Get rid of the red squigglies, and THEN try CTRL+K, CTRL+D, whatever...
Just wondering if anyone knows the keyboard shortcut to swap around two sides of a statement. For example:
I want to swap
firstNameTextbox.Text = myData.FirstName;
to
myData.FirstName = firstNameTextbox.Text;
Does anyone know the shortcut, if there is one? Obviously I would type them out, but there is a lot of statements I need to swap, and I think a shortcut like that would be useful!
Feel free to throw in any shortcuts you think are cool!
My contribution would be CTRL + E, D - this will format your code to Visual Studio standards! Pretty well known I'm guessing but I use it all the time! :)
UPDATE
Just to let everyone know, using a bit of snooping of the article that was posted, I managed to construct a regular expression, so here it is:
Find:
{.+\.Text = myData\..+};
And replace with:
\2 = \1;
Hopefully people can apply this to their own expressions they want to swap!
I think the following thread is a good place to begin with
Invert assignment direction in Visual Studio
Here's how I would go about doing that without a specific keyboard shortcut:
First, select the text you want to modify and replace
" = " with " = "
(the key here is to add a lot of spaces).
If you hold down Alt and use the mouse, you can select a "block" of code. Use this to select only the text on the right side of the equation (it's helpful to add extra white space here in your selection)
Use the same Alt + Left-Click combination to select the beginning of the left side (just select a blank area). You should be able to paste text into here.
If you added extra white space to the text you just added, just should be able to easily insert an = using the Alt + Click technique. Use the same trick to remove the equal sign that's dangling on the right side of your code block.
While this might not do exactly what you're looking for, I've found these tricks quite useful.
If you're using ReSharper, you can do this by pressing CtrlAltShift + ← or →
The feature is in Resharper. Select the code segment and click the content wizard, which is a pencil icon in the left corner reading View Actions List, then choose Reverse Assignment.
It is done.
swap-word is a VSCode extension which sounds like it would do what you want.
Quickly swap places two words or selections...
But I'm not sure if it is compatible with VS.
Since I was not happy with the answers where I need to enter complicated strings into the Visual Studio search/replace dialog, I wrote myself a little AutoHotkey script, that performs the swaps with only the need to press a keyboard shortcut. And this, no matter if you are in VS or in another IDE.
This hotkey (start it once simply from a textfile as script or compiled to exe) runs whenever Win+Ctrl-S is pressed
#^s Up::
clipboard := "" ; Empty the clipboard
Sendinput {Ctrl down}c{ctrl up}
Clipwait
Loop, Parse, clipboard, `n, `r ; iterates over seperates lines
{
array := StrSplit(RegExReplace(A_LoopField,";",""),"=") ; remove semicolon and split by '='
SendInput, % Trim(array[2]) . " = " . Trim(array[1]) . ";{Enter}"
}
return
Many more details are possible, e.g. also supporting code where lines end with a comma
...and I can put many more hotkeys and hotstrings into the same script, e.g. for my most mistyped words:
::esle::else ; this 1 line rewrites all my 'else' typos
I recommend using the find-replace option in Visual Studio. IMHO the REGEX string is not that complicated, and moreover, you don't need to understand the expression in order to use it.
The following regex string works for most programming languages:
([\w\.]+)\s*=\s*([\w\.]+)
For Visual Studio's you want to use $ argument in the replace text.
$2 = $1
Make sure to enable regex.
To do this in one shot, you can select a section of the document, and click the replace-all option.
Before:
comboBoxAddOriginalSrcTextToComment.SelectedIndex = Settings.Default.comboBoxAddOriginalSrcTextToComment;
comboBoxDefaultLanguageSet.SelectedIndex = Settings.Default.comboBoxDefaultLanguageSet;
comboBoxItemsPerTransaltionRequest.SelectedIndex = Settings.Default.comboBoxItemsPerTransaltionRequest;
comboBoxLogFileVerbosityLevel.SelectedIndex = Settings.Default.comboBoxLogFileVerbosityLevel;
comboBoxScreenVerbosityLevel.SelectedIndex = Settings.Default.comboBoxScreenVerbosityLevel;
After:
Settings.Default.comboBoxAddOriginalSrcTextToComment = comboBoxAddOriginalSrcTextToComment.SelectedIndex;
Settings.Default.comboBoxDefaultLanguageSet = comboBoxDefaultLanguageSet.SelectedIndex;
Settings.Default.comboBoxItemsPerTransaltionRequest = comboBoxItemsPerTransaltionRequest.SelectedIndex;
Settings.Default.comboBoxLogFileVerbosityLevel = comboBoxLogFileVerbosityLevel.SelectedIndex;
Settings.Default.comboBoxScreenVerbosityLevel = comboBoxScreenVerbosityLevel.SelectedIndex;
IMHO: It's better for a developer to learn to use the IDE (Integrated Development Environment), then to create new tools to do the same thing the IDE can do.
I already know about Ctrl + L to delete an entire line...is there one to just select an entire line (which I can then copy and paste somewhere else...)
You can also use Ctrl + X to cut an entire line. Similarly, you can use Ctrl + C to copy an entire line.
As long as you don't have anything selected, the command will work on the entire line.
Hit
Home
Shift + End
You can do it with Shift + DownArrow.
Yes there is. If you are in the begining of the line press Shift+ End.
If you are in the end of the line press Shift+ Home.
Hope that helps
I believe, if you don't have any selection and press Ctrl + C, it would copy the line.
Shift + End = Select between cursor and the end of the line
It's Home+Home, then Shift+Down for me.
Or you change that setting which makes Ctrl+C with no selection copy the line. But I hate that, so I always turn it off. (Thanks to Bala for providing the link to that setting!)
To cut a line, Ctrl+L works in my keyboard settings.
There's also Alt-Up and Alt-Down to move whole lines. It's two fewer keystrokes than using Ctrl-X, and unlike Ctrl-X, it also moves multiple whole lines at a time if your selection covers multiple lines even partially. It's also nice because the feedback is instantaneous, unlike Ctrl-X where you can never remember whether the pasted line will go above or below your cursor.
I saw this and thought I'd never use the feature. But once I got used to it I use it all the time. There's no easier way to move a block of code than using Shift-Up/Down to select the lines, press Alt-Up/Down a few times to move them, and then use Tab to adjust the indentation.
Of course it only works within the same file though.
Visual Studio macros are another way to do these types of operations if you can't find an existing command. A simple way to create one is:
Use the Record TemporaryMacro option (under Tools/Macros).
Select the line however you prefer (e.g., home, shift, end).
Click Stop Recording (under Tools/Macros).
Choose Save TemporaryMacro (under Tools/Macros).
Then choose Tools/Customize/Keyboard and assign a shortcut to the macro.
It's not specifically a keyboard shortcut, but a triple-click will select a whole line of code.
This works in some other areas of Windows as well. In Chrome, for example, double-click selects a word, but triple-click selects a paragraph.
(This works in Visual Studio 2013 on Windows 7. Not sure about other versions/platforms.)
I use Ctrl + Insert to copy entire line, and Shift + Insert to paste entire line.
Other answers require either using a mouse or hitting more than one combination.
So I've created a macro for those who want a VSCode-like Ctrl+L behaviour. It can select multiple lines.
