It looks like the last time the person visited the board was six months ago.
In any case, take a look at the examples and articles at --
MapPoint Articles - MP2K Magazine
Also, I would recommend the book --
Programming MapPoint in .NET
I did not have too much trouble with VB.NET and MapPoint 2004/2006, but I remember when I did have trouble it was frustrating to troubleshoot.
