I wrote some functions myself, and want to add them to the compilation system, so that when programming, you can call them just like iostream etc. just by adding #include<header file>?
Put it in the include folder in the installation directory.
For example: ..\Program Files\Microsoft Visual Studio\VC98\Include
Or: ..\Program Files\Microsoft Visual Studio 8\VC\PlatformSDK\Include
Tools->Option->Directories->Show directory for->include files
Then add your own header file path below, you can use #include<> elsewhere to use your own defined header file
There are 3 methods
1) Aslklklksaid, the simplest and most commonly used one
2) Project->setting->c/c++->Preprocessor->additional include directories
3) Assjtwenzhousaid, but this method is generally not used
