You can use this control to display a Visio drawing and allow the user to edit it. See the MSDN article above for a tutorial of using the control. Note that this will bind to a specific version of Visio. The user must have that version installed to use your app. There is a way of bundling up a lite installer with your app, that the article talks about. I would assume the user still has to have a Visio license, but I'm not sure.
