In my extension I use a custom tool window like its a document and open it multiple times with different content. This works great but the only problem is the save button on the main vs tool bar does not know anything about my custom tool window. When I have my custom tool window selected as the active window on the screen, the save button on the vs tool bar points to whatever the last document I was working on before I selected my custom tool window. How do I tell visual studio that I have a document open(my custom tool window) and when the save is click to send me that event so I can handle it?
I think this is possible because I see the TFS extension do it. When you add a new work item it displays a very custom window that has it's own save button but if you click save on the main vs tool bar it works too.
