Disabling autocompletion from anything else than Tab in VS 2022

Coco_l_asticot 20 Reputation points

Although I set "Default IntelliSense completion mode" to Tab-only in Text Editor/Advanced, Visual Studio keeps replacing text as I type with its first suggestion when I press e.g. space or dot. I do not want the editor to ever autocomplete unless I press Tab, apart maybe from closing parentheses, braces etc.

I thought this could possibly be due to a language-specific setting, so I also went into the C++ text editor settings and deleted all characters under "Text Editor/C/C++/Advanced/IntelliSense/Member List Commit Characters. But that didn't seem to solve the issue either. Any help is welcome...

    Hi @Coco_l_asticot

    Welcome to Microsoft Q&A! 

    Please re-run your VS as administrator. 

    You can use the option to change the IntelliSense completion mode: Edit > IntelliSense > Switch between automatic and tab-only IntelliSense completion or shortcut: Ctrl+Alt+Space. In suggestion mode, only the text you type is inserted into the code. 


    To disable autocomplete behavior when pressing space in a C++ project, you can go to Tools > Options > Text Editor > C/C++ > Advanced > IntelliSense > set “Use Aggressive Member List for Auto Member List” to “True”.

    This suggestion I received in the corresponding Developer Community thread solved the issue for me: In “Tools>Options>Text Editor>C/C++>Advanced”, under “IntelliSense”, set “Use Aggressive Member List for Auto Member List” to “True”
