In addition to what cathy said, there is a VBCommenter addin that is available for download on gotdotnet - including the VB source. You can even join the workspace and the virtual team that updates it. The workspace and the download (on the lower right of the page) is at:

>Hi All,
>
>How do I insert parameter descriptions in a custom sub and/or function so whenever I use the sub/function a tooltip appears indicating the required parameters and a brief description of what the parameter is for? Similar to built-in subs and functions in VB.NET. Currently, the only text in the tooltip for custom subs and functions are the parameters required (if any) and no descriptions for the parameters.
