No Intellisense but code completition?

[Culfa]

Hi I'm working now for WIN-API-Project. But it seems to be that there's no Intellisense. I searched for the code completition and I have it.
For Example I call the function TextOut();, the Intellisense does not appear. If i set a bracket, the bracket appears just then, when I tip a letter. (The <windows.h> is included). Furthermore the Intellisense does not work for point-operators. If I create a class, create an instance of it, call a function for the object, no Intellisense appears after the point-operator.

Are there any ideas?

PS: I have the nightly build from the 24.12.2007.
