Hi there. Im new to programming and just installed the DirectX 9.0 SDK (October 2005). I opened up the samples in my version of Visual Studio c++ (2005 Express Edition Beta Version 8.0.50215.44) and tried to build them. But I found that i had missing include files, (such as windows.h). Where can I get these headers or is there a new version of Studio i need to install

Include files

Why are you still using the express edition beta The full/final version is freely available now (see the announcement from David Weller in these forums)
The missing file - windows.h - is one of the "Platform SDK" components. You can download it from here.
