Parameter Info

Parameter info appears when you type a method name followed by a left parenthesis. 

Parameter info becomes available for virtually all methods, functions and macros. Methods can originate in system libraries, ATL/WTL/STL, third-party libraries and your own code. Virtually everything declared in headers included by your source is available. You do not need to build before parameter info is available.

Visual Assist versus Visual Studio

With Visual Assist, parameter info appears more often and with more accurate results for C/C++.

Default Intellisense generates the parameter info for C#.

Controlling Parameter Info

You can configure Visual Assist so it applies enhanced syntax coloring to parameter info as in the above example. The coloring is applied to parameter info of Visual Assist and that of default IntelliSense.

If you return to the middle of a parameter list, press Ctrl+Shift+Space to make parameter info reappear.

Use Up Arrow and Down Arrow to scroll through info for overloaded methods.

Press ESC to clear info. Info reappears when you type a comma and begin a subsequent argument, or press Ctrl+Shift+Space.

The current argument in parameter info is bold.

Options in Microsoft Visual Studio

If you want to see parameter info, enable Tools|Options|Text Editor|C/C++|General|Parameter information. If not, disable the option and restart the IDE to prevent Visual Assist from displaying info when the IDE does not.

You can prevent Visual Assist from augmenting IDE parameter information through registry settings.

Options in Microsoft Visual C/C++

If you want to see parameter info only from Visual Assist, disable Tools|Options|Editor|Auto parameter info, and disable Text Editor|Completion|Prefer default Intellisense in the Visual Assist options dialog. Enable Text Editor|C/C++ 6.0|Auto parameter info in the Visual Assist options dialog.

If you want to see parameter info from Visual Assist only when the IDE is unable to provide it, enable Tools|Options|Editor|Auto parameter info, and enable Text Editor|Completion|Prefer default Intellisense in the Visual Assist options dialog. Enable Text Editor|C/C++ 6.0|Auto parameter info in the Visual Assist options dialog.

If you do not want to see parameter info, disable Tools|Options|Editor|Auto parameter info, and disable Text Editor|C/C++ 6.0|Auto parameter info in the Visual Assist options dialog.

Restart your IDE to make changes take complete effect.
