I am guessing this post is related to your other post of not finding windows.h.
Express edition doesn't install the PSDK headers which windows.h is one of them.
You either need to install the PSDK seperately or install a pro, or TS version of VS2005.
Please see this related post for more info:

Also, see http://lab.msdn.microsoft.com/vs2005/get/ for information on the different editions of VS2005.

Hi Yanick,
