Creating Visio add in from VS 2005

[irishjoe]

Hi, I am trying to create a simple addon for visio 2007 from visual studio 2005 but have hit a brick wall. When running code to create a new shape, the code runs until this point then just stops and jumps back into visio from VS.

I have followed this guide but when it gets to the adding a shape to the page, the code stops running.

I have checked the references that the guide says I need and they are in my project.

Has anyone had the same problem or know of a different guide I could follow to get started?

Cheers.
