Microsoft Vs Code Cannot Edit In Read-only Editor

-->

  • Visual Studio Code vs. Visual Studio: How to choose Deciding between Visual Studio Code and Visual Studio may depend as much on your work style as on the language support and features you need.
  • Select install, and once it is installed VS code informs you that the PAC CLI is ready to be used within the Terminal window. To initiate the Power Platform CLI, go to the terminal window, and select a new terminal and the new extension is up and running. Now type in pac you will see the list of command that are now available.

I had the Cannot edit in read-only editor error when trying to edit code after stopping the debug mode (for 2-3 minutes after pressing Shift+F5). Turns out the default Node version (v9.11.1) wasn't exiting gracefully, leaving VScode stuck on read-only. Simply adding 'runtimeVersion': '12.4.0' to my launch.json file fixed it.

By changing these options, you can change the behavior related to IntelliSense and the browsing database when you're programming in C or C++.

To access this page, in the Options dialog box, in the left pane, expand Text Editor, expand C/C++, and then choose Advanced.

Note

Your computer might show different names or locations for some of the Visual Studio user interface elements in the following instructions. The Visual Studio edition that you have and the settings that you use determine these elements. See Personalize the Visual Studio IDE.

Browsing/Navigation

You should never choose these options except in the rare case where a solution is so large that the database activity consumes an unacceptable amount of system resources.

Disable Database

All use of the code browsing database (SDF), all other Browsing/Navigation options, and all IntelliSense features except for #include Auto Complete are disabled.

Disable Database Updates

The database will be opened read-only, and no updates will be performed as files are edited. Most features will still work. However, as edits are made, the data will become stale, and you'll get incorrect results.

Disable Database Auto Updates

The code browsing database won't be automatically updated when source files are modified. However, if you open Solution Explorer, open the shortcut menu for the project, and then choose Rescan Solution, all out-of-date files will be checked, and the database will be updated.

Disable Implicit Files

The code browsing database doesn't collect data for files that aren't specified in a project. A project contains source files and header files that are explicitly specified. Implicit files are included by explicit files (for example, afxwin.h, windows.h, and atlbase.h). Normally, the system finds these files and also indexes them for various browsing features (including Navigate To). If you choose this option, those files aren't indexed, and some features aren't available for them. If you choose this option, 'Disable Implicit Cleanup' and 'Disable External Dependencies' are also implicitly chosen.

Disable Implicit Cleanup

The code browsing database doesn't clean up implicit files that are no longer referenced. This option prevents implicit files from being removed from the database when they're no longer used. For example, if you add an #include directive that references mapi.h to one of your source files, mapi.h will be found and indexed. If you then remove the #include and the file isn't referenced elsewhere, information about it will eventually be removed unless you choose this option. (See the Rescan Solution Interval option.) This option is ignored when you explicitly rescan the solution.

Disable External Dependencies Folders

The External Dependencies folder for each project isn't created or updated. In Solution Explorer, each project contains an External Dependencies folder, which contains all implicit files for that project. If you choose this option, that folder doesn't appear.

Recreate Database

Recreate the code browsing database from nothing the next time that the solution loads. If you choose this option, the SDF database file is deleted the next time you load the solution, thus causing the database to be recreated and all files indexed.

Rescan Solution Interval

A 'Rescan Solution Now' job is scheduled for the interval that you specify. You must specify between 0 and 5000 minutes. The default value is 60 minutes. While the solution is rescanned, file timestamps are checked to determine whether a file was changed outside of the IDE. (Changes that are made in the IDE are automatically tracked, and files are updated.) Implicitly included files are checked to determine whether they're all still referenced.

Diagnostic Logging

These options are provided in case Microsoft asks you to collect advanced information to diagnose an issue. The logging information isn't useful for users, and we recommend that you leave it disabled.

Enable Logging

Enables diagnostic logging to the output window.

Logging Level

Set the log verbosity, from 0 to 5.

Logging Filter

Filters displayed event types by using a bitmask.

Set by using a sum of any of the following options:

  • 0 - None

  • 1 - General

  • 2 - Idle

  • 4 - WorkItem

  • 8 - IntelliSense

  • 16 - ACPerf

  • 32 - ClassView

Fallback Location

The fallback location is where the SDF and IntelliSense support files (for example, iPCH) are put when the primary location (same directory as solution) isn't used. This situation could occur the user doesn't have the permissions to write to the solution directory or the solution directory is on a slow device. The default fallback location is in the user's temp directory.

Always Use Fallback Location

Indicates that the code browsing database and IntelliSense files should always be stored in a folder that you specify as your 'Fallback Location', not next to the .sln file. The IDE will never try to put the SDF or iPCH files next to the solution directory and will always use the fallback location.

Do Not Warn If Fallback Location Used

You aren't informed or prompted if a 'Fallback Location' is used. Normally, the IDE will tell you if it had to use the fallback location. This option turns off that warning.

Fallback Location

This value is used as a secondary location to store the code browsing database or IntelliSense files. By default, your temporary directory is your fallback location. The IDE will create a subdirectory under the specified path (or the temp directory) that includes the name of the solution along with a hash of the full path to the solution, which avoids issues with solution names being identical.

IntelliSense

Auto Quick Info

Enables QuickInfo tooltips when you move the pointer over text.

Disable IntelliSense

Disables all IntelliSense features. The IDE does not create VCPkgSrv.exe processes to service IntelliSense requests, and no IntelliSense features will work (QuickInfo, Member List, Auto Complete, Param Help). Semantic colorization and reference highlighting are also disabled. This option doesn't disable browsing features that rely solely on the database (including Navigation Bar, ClassView, and Property window).

Disable Auto Updating

IntelliSense updating is delayed until an actual request for IntelliSense is made. This delay can result in a longer execution time of the first IntelliSense operation on a file, but it may be helpful to set this option on very slow or resource-constrained machines. If you choose this option, you also implicitly choose the 'Disable Error Reporting' and 'Disable Squiggles' options.

Disable Error Reporting

Disables reporting of IntelliSense errors through squiggles and the Error List window. Also disables the background parsing that's associated with error reporting. If you choose this option, you also implicitly choose the 'Disable Squiggles' option.

Disable Squiggles

Disables IntelliSense error squiggles. The red 'squiggles' don't show in the editor window, but the error will still appear in the Error List window.

Online

Auto Tune Max Cached Translation Units

The maximum number of translation units that will be kept active at any one time for IntelliSense requests. You must specify a value between 2 and 15. This number directly relates to the maximum number of VCPkgSrv.exe processes that will run (for a given instance of Visual Studio). The default value is 2, but if you have available memory, you can increase this value and possibly achieve slightly better performance on IntelliSense.

For more information about translation units, see Phases of Translation.

Disable #include Auto Complete

Disables auto-completion of #include statements.

Use Forward Slash in #include Auto Complete

Triggers auto-completion of #include statements when '/' is used. The default delimiter is backslash '. The compiler can accept either, so use this option to specify what your code base uses.

Disable Aggressive Member List

The member list doesn't appear while you type the name of a type or variable. The list appears only after you type one of the commit characters, as defined in the Member List Commit Characters option.

Disable Member List Keywords

Language keywords such as void, class, switch don't appear in member list suggestions.

Disable Member List Code Snippets

Code snippets don't appear in member list suggestions.

Member List Filter Mode

Sets the type of matching algorithm. Fuzzy finds the most possible matches because it uses an algorithm that's similar to a spell-checker to find matches that are similar but not identical. Smart filtering matches substrings even if they're not at the start of a word. Prefix only matches on identical substrings that start at the beginning of the word.

Disable Semantic Colorization

Turns off all code colorization except for language keywords, strings, and comments.

Member List Commit Characters

Specifies the characters that cause the currently highlighted Member List suggestion to be committed. You can add or remove characters from this list.

Smart Member List Commit

Adds a line when you choose the Enter key at the end of a fully typed word.

Enable Member List Dot-To-Arrow

Replaces '.' with '->' when applicable for Member List.

References

Disable Resolving

For performance reasons, 'Find All References' displays raw textual search results by default instead of using IntelliSense to verify each candidate. You can clear this check box for more accurate results on all find operations. To filter on a per-search basis, open the shortcut menu for the result list, and then choose 'Resolve Results.'

Hide Unconfirmed

Hide unconfirmed items in the 'Find All References' results. If you unset the 'Disable Resolving' option, you can use this option to hide unconfirmed items in the results.

Disable Reference Highlighting

By default, when you select some text, all instances of the same text are automatically highlighted in the current document. You can disable this feature by setting Disable Reference Highlighting to True.
