Visual c++ DirectX compilation error - visual-c++

Question

Can any one help me with this error ?
And I have Linked to d3d10.lib and d3dx10.lib.
I am new to directX stuff and I was following wendy jones DirectX 10 toturial

Answer 1

It's a problem of linkage, did you add the right library in your visual studio ?

Answer 2

Add D3D10.lib to the list of linker dependencies.

Answer 3

What about your include folder in your hard drive?
You need to go to that through your includes and also added in lib/86 to library dependances.
Follow the steps in this link: http://www.rastertek.com/dx10tut01.html
This will take you through the process of setting up DirectX. Worst happens and you do it and you still get the same problem, you know its not a linker issue. Which 4 people have now told you it is.
Also this site is great for taking you through DirectX as well. I highly advise.
