How to include a .h file correctly in VC++?
I have a very simple window form program which is 100% working alright.

Since I want to add call internet explorer when I click a button on my window form, I add "ONE LINE of code" for testing purpose.

I add **#include "Shellapi.h"** under **#pragma once**. After that, VS gives me 500 lines of error message.

My question is that I am only adding a .h file into my program. Why there will cause any problem? Do I miss something?
