intellisense not showing properties in visual studio add-in

When i hit Ctrl+Space to invoke intellisense in a QHash object, Visual Studio 2008 says: "has a type that could not be resolved" and don't show the methods.
The problem appear to be in the include directories add-in plugin had created.
It is a simple problem with a simple solution:
Instead of "$(QTDIR)\include\qtmain like the instalation made it need to be:
$(QTDIR)\include\Qt

i did this and now intellisense is working perfectly.
Could someone mmake this change in the next add-in release?

thx
