I have been looking to make an MS Project add-in tool for myself, and came across one by Structured Solutions Inc. This add in has what seems to be a dockable window custom made by them and I was wondering what they did to make something like that. My current plan is to use VSTO, but I can't find any documentation showing that this is even possible.
