[RESOLVED] vs2022, how to comment large blocks of code?. entire subs at once

[sdowney1]

I have 2 subs, like to just comment all without individually putting single quote on each line

Probably with #IF but I have never tried it.

Try selecting the code then press Ctrl-/ (hold the Ctrl key and press /) ... most IDEs use that for block (un)commenting... I know VSCode does it, so I assume Visual Studio will do the same.

In VS2022 select View > Toolbars > Text Editor.

This toolbar has a comment and uncomment button on it. You can highlight as much of your code as you want and then press the comment button and it will comment it all out at once, and vice versa for uncomment.

If you'd rather use keyboard shortcuts then it is CTRL+K Then CTRL+C to comment out your selected code, and CTRL+K Then CTRL+U to uncomment. You can press K then C or U while holding down control.

Thanks, CTRL+K Then CTRL+C worked

First highlight text then do that.

Useful to me when developing subs, to make changes but keep the old working code just in case.
Then also, I like to keep some code in comments in modules as examples of how to do things.

I use the buttons that themindgoblin showed. The shortcut keys are also pretty nice, but Ctrl+C is always a bit risky, because that's Copy. You aren't as likely to make a mistake with that as you are with Ctrl+P or Ctrl+X, but re-use of Ctrl+ in this fashion can be awkward if you care also copying and pasting.

Thanks, CTRL+K Then CTRL+C worked.

Note 1) Remember to uncomment the highlighted section by Ctrl + K then Ctrl + U.
Note 2) Layering comments by re-pressing shortcuts, helps priorized uncommenting and code engaging for dev purposes.
Note 3) Remember to close the thread once you get a proper answer.

You can collapse a sub, like so...





Then highlight the entire collapsed code stub, and click the comment button on your toolbar. There's also an uncomment button that you can use to uncomment a sub or a block of commented code...

Thanks, all very helpful.

So.

        Dim i As Integer
        Dim x As Integer

        x = 123

#If 0 Then
      
        i = 2

      
        x = 5
#End If

        x = 4
        i = 3

I'm testing this and it works better, you don't need to select oceans of code and quote them. Of course makes no sense for a line or two but for more it looks even better than C# /*

Unfortunately I'm more on C# at the company now so that is a really late find, still it simulates a region of commend out code better than quoting everything, you just have to get used to it.
